For those who can stomach it,working out before breakfast may be more beneficial for health than eating first,according to a study of meal timing and physical activity.

Athletes and scientists have long known that meal timing affects performance.However,far less has been known about how meal timing and exercise might affect general health.

To find out,British scientists conducted a study.They first found 10 overweight and inactive but otherwise healthy young men,whose lifestyles are,for better and worse,representative of those of most of us.They tested the men's fitness and resting metabolic (新陈代谢的) rates and took samples (样品) of their blood and fat tissue.

Then,on two separate morning visits to the scientists' lab,each man walked for an hour at an average speed that,in theory,should allow his body to rely mainly on fat for fuel. Before one of these workouts,the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast(禁食).On the other occasion,they ate a rich morning meal about two hours before they started walking.

Just before and an hour after each workout,the scientists took additional samples of the men's blood and fat tissue.

Then they compared the samples.There were considerable differences.Most obviously,the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten.As a result,they burned more fat during walks on an empty stomach than when they had eaten first.On the other hand,they burned slightly more calories(卡路里), on average,during the workout after breakfast than after fasting.

But it was the effects deep within the fat cells that may have been the most significant,the researchers found Multiple genes behaved differently,depending on whether someone had eaten or not before walking.Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin(胰岛素) levels throughout the body and so are associated with improved metabolic health.These genes were much more active when the men had fasted before exercise than when they had breakfasted.

The implication of these results is that to gain the greatest health benefits from exercise,it may be wise to skip eating first.

(1)The underlined expression "stomach it" in Paragraph 1 most probably means "    ".

A.

digest the meal easily

B.

manage without breakfast

C.

decide wisely what to eat

D.

eat whatever is offered

(2)Why were the 10 people chosen for the experiment?   

A.

Their lifestyles were typical of ordinary people.

B.

Their lack of exercise led to overweight.

C.

They could walk at an average speed.

D.

They had slow metabolic rates.

(3)What happened to those who ate breakfast before exercise?    

A.

They successfully lost weight.

B.

They consumed a bit more calories.

C.

They burned more fat on average.

D.

They displayed higher insulin levels.

(4)What could be learned from the research?   

A.

A workout after breakfast improves gene performances.

B.

Too much workout often slows metabolic rates.

C.

Lifestyle is not as important as morning exercise.

D.

Physical exercise before breakfast is better for health.

During a state of deep relaxation, several physiological changes take place in the body: the body’s oxygen consumption is reduced; the heart beat decreases; muscle tension and sweating ease, and there is decreased sympathetic (交感的) nervous system activity.This restful state not only allows the body to repair and restore itself, but it has a calming effect on the consciousness.
How to achieve this state of relaxation, however, is a matter of opinion, and in some medical circles, a matter of controversy.A recent report by Dr.David Holmes of the University of Kansas in the journal “American psychologist” said that simply sitting in an armchair has just as many beneficial characteristics for the body as meditation (冥想) does.Researchers of other relaxation techniques disagree.These experts believe that more structured techniques, such as meditation, lead to a condition of deep relaxation.
The debate goes on, but one thing appears to be clear: the relaxation response can be reached by a number of methods, and the methods themselves are not as important as getting there.One day, one method may work best; on another day, an alternative method may be more appropriate.Once you are aware of all the methods, you can find the one that works best on you.
Some of the relaxation techniques are meditation, auto analysis and progressive muscle relaxation response.More than just sitting quietly in a chair, they have the added benefit of structure and discipline, and for these reasons appear to be more effective for most individuals.
According to the passage, which of the following statements is NOT true when a person is in a state of deep relaxation?

A.The body takes in less oxygen.
B.The heart beats less frequently.
C.Muscles become tense and the body sweats easily.
D.The consciousness becomes more or less calmed.

People seem to agree that ____.

A.sitting in an armchair benefits a person as meditation does
B.structured relaxation techniques are more beneficial for a person
C.to achieve a state of deep relaxation is possible through various means
D.what people are all struggling for is a state of deep relaxation

In the third paragraph, the phrase “getting there” means _____.

A.arriving at one’s destination
B.getting what one wants most
C.finding out a suitable relaxation technique
D.reaching a state of deep relaxation

The author’s attitude toward relaxation discussed in the passage is best described as ______.

A.sceptical B.objective C.optimistic D.critical

Not so long ago almost any student who successfully completed a university degree could find a good career quite easily.Companies toured the academic institutions, competing with each other to select graduates.However, those days are gone, even in Hong Kong, and nowadays graduates often face strong competition in the search for jobs.
Most careers organizations highlight three stages for graduates to follow in the process of securing a suitable career:recognizing abilities, matching these to available jobs and presenting them well to possible employers.
Job seekers have to make a careful assessment of their own abilities.One area of assessment should be of their academic qualifications, which would include special skills within their subject area.Graduates should also consider their own personal values and attitudes.An honest assessment of personal interests and abilities such as creative skills, or skills acquired from work experience, should also be given careful thought.
The second stage is to study the opportunities available for employment and to think about how the general employment situation is likely to develop in the future.To do this, graduates can study job and position information in newspapers, or they can visit a careers office, write to possible employers for information or contact friends or relatives who may already be involved in a particular profession.After studying all the various options, they should be in a position to make informed comparisons between various careers.
Good personal presentation is essential in the search for a good career.Job application forms and letters should, of course, be filled in carefully and correctly, without grammar or spelling errors.Where additional information is asked for, job seekers should describe their abilities and work experience in more depth, with examples if possible.They should try to balance their own abilities with the employer’s needs, explain why they are interested in a career with the particular company and try to show that they already know something about the company and its activities.
When graduates go to an interview, they should prepare properly by finding out all they can about the possible employer.Dressing suitably and arriving for the interview on time are also important.Interviewees should try to give positive and helpful answers and should not be afraid to ask questions about anything they are unsure about.This is much better than pretending to understand a question and giving an unsuitable answer.
“Those days are gone, even in Hong Kong” in Paragraph 1 suggests that__________.

A.finding a good career used to be easier in Hong Kong than elsewhere
B.now everyone in Hong Kong has an equal chance of finding a good job
C.graduates now face stronger competition in Hong Kong than elsewhere
D.even in Hong Kong companies tour universities trying to select graduates

It is implied in Paragraph 3 that graduates should_____________.

A.aim to give a balanced account of what the employer needs
B.consider careers which suit their values, interests and abilities
C.stress their personal attitudes and values in job applications
D.recognize their own abilities regardless of what the employer looks for

According to Paragraph 4, graduates should______________.

A.find a good position and then compare it with other careers
B.ask friends or relatives to secure them a good job
C.get information about a number of careers before making comparisons
D.study the opportunities and the kinds of training that will be available

In the last paragraph, the writer seems to suggest that ________________.

A.interviewees should appear humble if they can’t give an answer
B.dressing properly is more important than being able to give an answer
C.it is better for interviewees to be honest than to pretend to understand
D.it is a good idea for interviewees to be boastful in their answers

One day in January, my uncle, my cousin and I decided to go hunting.We left by car in the afternoon.It was a Range Rover with four-wheel drive.It took us three hours to get there.After we arrived at 5:15 p.m., we fixed the tent, then made coffee and had a short rest.After that, we went hunting, using a falcon(猎鹰).We spent two hours without finding anything.On our way back to the camp, my cousin saw a rabbit.I removed the falcon’s bead cover and let go of the aggressive falcon.When the rabbit saw the falcon, it ran fast, but my falcon was a professional hunter.He flew up and came down to trick the rabbit.After two minutes, the rabbit was caught.We took it back to the camp to cook our dinner.We ate the delicious food, drank Arabic coffee, and sat around the fire talking until 10:30 p.m.
We left the camp the next day at 7 o’clock in the morning.We went north.However, around 10:00 a.m.our car got stuck in the sand! We spent about three hours trying to pull out the car without any progress.Finally, we decided to walk.As it was hard for an old man or a young boy to walk more than 40km in the desert, I decided to get help myself.I took a bottle of water with me and started to walk south alone.I knew the way well, but it was a long way in the sand.I walked more than four hours without stopping.When I felt so tired and thirsty, I stopped to rest.I drank all the water and slept for around two hours.
When I got up, it was dark.I continued to walk south.I was worried about my uncle and cousin.Suddenly, I met a Bedouin man who was riding his camel.He took me to his house.When I had had enough rest, I asked him to take me to the road where I found a car.It took me to the city to get help.I had one day to get back to my uncle and cousin.When I got back to them, they were so happy because I had gotten help and they were able to see me again.

I keep hammering this because I keep seeing people who don’t do it.
1.Look up English to Elvish.
2.Look up the Elvish word in the best Elvish dictionary you have, and, preferably, find out the context in Tolkien’s language dictionary.
3.Change the word to suit rules of grammar: singular or plural, mutations, verb tenses, etc.
You cannot leave out any of these steps.If you do, you’re almost certain to have errors.Why you have to do step 2:
Languages never match up one- to-one.English and Elvish are closer than usual, but there are still problems.And English has strange idioms: why are there no baths or beds in public bathrooms or restrooms? You can’t translate literally.You have to understand the meaning behind each word.
In Elvish this is even more true, since our dictionaries contain more or less questionable reconstructions, and words that Tolkien later threw away or replaced.Find the best one you can.
Consider the word “fair”.We tend to use it to mean “just”.Tolkien tends to use it to mean “beautiful”.In Elvish, these are two entirely different words.So when you look up “fair”, you’ll have to go to the Elvish dictionary to see that you’ve got the right one.
Consider the nightmare of He left the bar.Is “left” the opposite of “right” (which also has two meanings) ? Is “bar” extruded steel(型材钢), or something to do with law? You have to know what words mean in both languages.
And you’d be amazed at how many people ignore step 3, forgetting that language is more than a string of words, and there are rules about how to fit those words together.You can’t simply look up the word “I” and use it everywhere.Sometimes you need “me” or “my”.There’s a reason it takes a while to learn a language: you have to learn the rules.
It drives me completely mad when people give a questionable translation they insist is right because “it’s in the dictionary”.A dictionary is a tool, a resource.but its entries(词目)should not be mistaken for a finished product.They are raw materials.
The underlined word “this” in paragraph 1 refers to

A.consulting the dictionaries when translating between languages
B.finding out the true meaning in context
C.ignoring the rules of grammar
D.leaving out some of the three steps the author mentions

According to the author, you have to do step 2 because

A.you have to understand the meaning behind each word
B.Elvish and English are quite different in forms
C.there are no baths or beds in public bathrooms
D.Elvish has some words which are hard to find

Grammar is also very important because it

A.helps fit the words together B.takes a while to learn a language
C.is a rule to obey D.is often forgotten in translating

In the last paragraph, the author shows

A.his impatience to those who insist their wrong translation is right
B.his puzzle to the questionable translation
C.the importance of the correct use of dictionaries
D.the mistaken entries in the dictionaries

The passage is mainly about how to

A.learn a foreign language with a dictionary
B.avoid errors when looking up a dictionary
C.understand the meaning of a strange word
D.use a dictionary to translate between languages

What is the relationship between violence and sports? Psychologists say that there are many reasons for violence at sports events. One is alcohol. Many fans drink a lot at games. When people drink, they are more likely to do abnormal things. Psychologist Dennis Brock says, “Quiet people become loud. Normally nonviolent people become destructive. ”
David Sampson, a sports sociologist, says, “These are often celebratory riots— a large number of very happy people mixed in with large amounts of alcohol. They don’t often seem dangerous in the beginning, but things get violent quickly. ”
Another reason for violence at sports events is the crowd. When individuals are in a large group of people, they can lose their sense of personal responsibility. Edward Hirt, a social Psychologist, says that research shows that people do things in crowds that they would never do alone. People in crowds feel anonymous — no one knows who they are. Crowds also make people feel powerful. They stop making personal decisions. They just follow the crowd. Social psychologists call this a “mob mentality.”
Dave Zarifis, head of public safety says, “Some people don’t even come to celebrate. They want to drink hard and make trouble. Someone does something stupid, and it grows from there. You get a mob mentality. People think it’s OK to do almost anything. They think, ‘There are so many of us and not enough of them. ’ ”
Social psychologist Dr. Sharon Kennedy says that there are some things officials can do to prevent violence. Making sure that an area is not overcrowded is very important. Officials should also think of games as “big parties.” Then they will prepare differently. Kennedy says that in Great Britain they are controlling the problem with cameras in all the stadiums. “When you know someone is watching, you are much less likely to behave badly. ”
Which of the following best gives the main idea of the first two paragraphs?

A.There’s a connection between violence and sports
B.One cause of violence at sports events is alcohol.
C.There are many reasons for violence at sports events.
D.David Sampson and Dennis Brock have the same opinion.

Which of the following does NOT belong to a “mob mentality”?

A.“I must drink some alcohol to stop myself feeling shy. ”
B.“ It’s safe to do what many people are doing. ”
C.“There are so many of us and not enough of them. ”
D.“ No one knows I’m doing this. ”

How many experts are quoted by the writer of this passage?

A.Two. B.Four. C.Three. D.Five.

The last paragraph is mainly about ______.

A.how to turn games into big parties
B.why to install cameras in stadiums
C.how to prevent violence at sports events
D.how to avoid oneself behaving badly

What lesson can we learn from this passage?

A.Never drink any alcohol no matter where you are.
B.Whenever you are watching a game, you should keep quiet.
C.Never follow blindly no matter how many people are doing something.
D.Be careful when you are at a stadium because there are cameras there.
