Who hasn't found themselves reaching for the closest food available when they're tired and stressed? More and more research is proving that this isn't all in our mind. Some foods really do lead to a change in our moods (心情).
Carbohydrate (碳水化合物) for calm
This is how some people medicate(治疗) themselves with food — by reaching for cookies or pasta(意大利面食) whenever they're upset.  Unfortunately, it doesn't always work.  You must eat a meal consisting of 100% carbohydrate, on an empty stomach, to obtain the serotonin (血清素) increase so that you have a good mood.
To get the wishedfor effect, you must not eat anything for four hours and then eat at least 30 grams of straight carbohydrate. Dry cereal (谷类食品), a piece of bread with jam, or a potato should do_the_trick.
Protein (蛋白质) for power
Of course, sometimes we don't need to be calm and sleepy.Sometimes we need a great deal of mental concentration, so this is when it's important to mix protein and carbohydrate. The protein will prevent the tryptophan (色氨酸) from flooding your brain,and the rise in serotonin(血清素) won't occur.
Why dessert makes us happy
Fat and sugar cause the brain to let go endorphins (内啡肽), which send pleasure signals throughout the body. This would be fine, except humans are not particularly good at stopping at one cookie or cake.
You can also satisfy your sweet tooth by choosing fruit for dessert.
Timing your meals for energy
Blood sugar drops after four hours of going without food, causing a decrease(减少) in energy. Eating usually fixes this within 20 to 30 minutes, but don't suppose that eating more will cause a faster increase in energy.
When you eat has as much of an effect on your mood as what you eat.  If you regularly go for a long period of time between meals, rethink your schedule and plan ahead.
The underlined phrase“do_the_trick”in the third paragraph means ________.

A.be extremely smart
B.intend to cheat someone
C.bring about the desired result
D.do something to amuse people

The function of protein is ________.

A.to help you keep calm and sleepy
B.to make you feel energetic
C.to lead you to slowness
D.to increase serotonin in your brain

We can infer from the last two parts that ________.

A.fat and sugar can greatly help people feel happy
B.we humans tend to eat lots of cookies and cakes
C.the more we eat, the faster we will gain energy
D.what we eat is more important than when we eat

The main idea of the passage is ________.

A.eating for a better mood
B.eating to make you calm
C.eating for more protein
D.eating to make us strong

Meat and vegetables are measured in grams and kilograms. Milk and other liquid foods are measured in liters or milliliters. These units only measure quantity; they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie which is the amount of heat given off by food when it burns. This measurement tells how much energy a certain food has when it is completely used by the body.
Our bodies use varying amount of calories. The more exercise we take, the more calories we burn. If we eat food which contains more calories than we use up, then it is possible that we would increase in weight. In order to avoid becoming overweight, it is advisable to eat a balanced diet and not eat too many foods that have a high calorie rating. The table below gives you some idea of the number of calories in food.
A. Meats B. Fruits C. Sweets and Pastries D. Vegetables

Mark Twain was a great writer. He was from the USA. He was born in 1835. He was also a famous speaker. He was famous for his sense of humour. Many people liked to listen to him talk because he liked to tell some interesting stories to make people laugh all the time.
One day Mark Twain was going to a small town because of his writing. Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he’d better not go there. Mark Twain waved his hand and said, “It doesn’t matter. The mosquitoes are no relatives of mine. I don’t think they will come to visit me.”
After he arrived at the town, Mark Twain stayed in a small hotel near the station. He went into his room, but when he was just about to have a rest, quite a few mosquitoes flew about him. The waiters felt very sorry about that. “I’m very sorry, Mr Mark Twain. There are too many mosquitoes in our town.” One of them said to him.
Mark Twain, however, made a joke, saying to the waiter, “The mosquitoes are very clever. They know my room number. They didn’t come into the wrong room.” What he said made all the people present laugh heartily.

As bananas ripen, the green skin turns ye11ow gradually. Chemical changes occur in the flesh of the fruit as well:starch(淀粉)changes to sugar;pectin(果胶)breaks down,losing its stiffness; and the flesh softens.
Is ripening fruit a self-contained system, or is the rate of these changes affected by the environment? We designed the experiment below to see if different atmospheres, produced by different packaging, affected the rate of ripening. You will vary the atmosphere surrounding unripe bananas and observe the effect on the ripening process。
Now set up the bananas in their environments as follows:
1. Put two green bananas in a paper bag and fo1d the top over to seal out the air.
2.Put one green banana and the very ripe banana in the other paper bag and fold over the top.
3. Put two green bananas in a plastic bag and seal it.
4. Wrap(包)one green banana tightly in a plastic bag.
5. Leave one green banana exposed to the air.
Leave the fruit a1one for five days to ripen. Ripening fruit “breathes”. This means that it takes up oxygen and gives off C02. Oxygen is extremely important and necessary for the chemical reactions involved in ripening. In addition, ripening fruit gives off another gas, called ethylene(乙烯). Not only is ethylene a product of ripening fruit, it also promotes the further ripening of the fruit.
Paper bags tend to keep the ethylene in, but they allow oxygen and ethylene to pass through slowly. Plastic bags do not allow the free flow of oxygen or ethylene. In this experiment, the green banana in paper bag with the ripe banana should ripen most quickly. The green bananas in the paper bag should ripen faster than the bananas in the plastic bag. The banana left exposed to air has an unlimited supply of oxygen, so it will turn brown most quickly. You will notice that the side of this banana that rests on the counter will ripen more quickly than the other sides, because it has the closest contact(接触) with its own ethylene. The banana that is tightly wrapped in plastic has no oxygen supply and should ripen most slowly. Now can you see why bananas are sealed in plastic in many supermarkets?
57. What makes the green banana in Bag 2 ripen more quickly than the ones in Bag 1?
A. Ethylene from the very ripe banana. B. The free flow of oxygen or ethylene
C. C02 from the very ripe banana. D. The limitation of oxygen supply.
58. How can we slow down the ripening of bananas exposed to the air?
A. To rest them on the counter. B. To keep them in the basket.
C. To put them on the ground. D. To hang them up from the ceiling
59. It can be concluded from the passage that_______ .
A. the ripening banana is a self-contained system
B. the rate of ripening bananas is affected by the environment
C. wrapped bananas experience no chemical changes to ripen
D. ripening bananas give off oxygen, C0, and ethylene
60. Why are bananas sealed in plastic in many supermarkets?
A. To make them ripen more quickly. B. To make them ripen more slowly.
C. To make banana flesh soften. D. To turn green bananas yellow.

For the people living in the Nile Basin, the river is their life:. This 6,825 km waterway, whose watershed(流域) covers three million square kilometers, flows through mountains ,woodlands, lakes and deserts. Its potential for fishing, tourism and shipping is great—but so are its challenges.
Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well. Today, about 160 million people depend on the Nile River for their living. Within the next 25 yeas ,the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture. The frequent drought(干旱)adds to the urgency.
Water quality is also a problem. Precious soil is washed out to sea. Wastes from industry and agriculture create pollution. Higher concentrations of salt influence irrigated soils. Water-borne diseases continue unchecked. In areas where it's hot and damp, water hyacinths choke off(阻止) lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day. They’ve seen the river change course, and their only source(来源) of water thickened with mud. They’re very poor and have few choices.
But a new program, the Nile Basin Initiative (NBI), is offering very practical assistance. The program is more than just a water-management project. It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions(解决办法). Half the Nile Basin's countries are among the world's poorest nations;yet, somehow, they must find the resources, skills and political will to overcome these challenges.
53. What are the great challenges the Nile Basin faces?
A. The development of .shipping industry.
B. Overfishing of native people.
C. Water shortage and water quality.
D. Increasing population and tourism.
54. The underlined word “hyacinths” (in Paragraph 3) refer to “_______”.
A. animals B. plants C. rocks D. salts
55. The program NBI is mainly aimed at _______ .
A. preventing water pollution
B. changing the river course
C. improving living condition of the poor
D. preventing land from becoming desert
56. What would be the best title of this passage?
A. People's Life in Egypt and Sudan
B. Frequent Drought in Egypt and Sudan
C. The Poorest Countries in the Nile Basin
D. The Ecosystem Problems in the Nile Basin

Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time? When you select your career, there’s whole lot more to it than assessing your skills and matching them with a particular position. If you ignore your personality, it will hurt you long-term regardless of your skills or the job's pay. There are several areas of your personality that you need to consider to help you find a good job. Here are a few of those main areas:
1) Do you prefer working alone or with other people?
There are isolating(使孤立) jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy. Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.
2) How do you handle change?
Most jobs these days have some elements of change to them, but some are more than others. If you need stability in your life, you may need a job where the changes don't happen so often. Other people would be bored of the same daily routine.
3) Do you enjoy working with computers?
I do see this as a kind of personality characteristic. There are people who are happy to spend more than 40 hours a week on a computer, while there are others who need a lot of human interaction throughout the day. Again, these are extremes and you'll likely find a lot of positions somewhere in the middle as well.
4) What type of work environment do you enjoy?
This can range from being in a large building with a lot of people you won't know immediately to a smaller setting where you'll get to know almost all the people there fairly quickly.
5) How do you like to get paid?
Some people are motivated by the pay they get, while others feel too stressed to be like that. The variety of payment designs in the sales industry is a typical example for this.
Anyway, these are a great starting point for you. I've seen it over and over again with people that they make more money over time when they do something they love. It may take you a little longer, but making a move to do what you have a passion for can change the course of your life for the better.
49.This passage mainly talks about the importance of _______in jobs.
A.different payment B.personalities
C.personal skills D.job’s pay
50.Which of the following is TRUE according to the passage?
A.Isolating jobs usually drive people mad.
B.Interactive jobs make people shy easily.
C.Extreme people tend to work with others.
D.Almost everyone has a tendency in jobs.
51.What is the missing word about a job search in the following chart?
A.Design B.Skills C.Cooperation D.Hobbies


52.What is the best title for this passage?
A.Lifestyles and Job Pay B.Jobs and Environment
C.Job Skills and Abilities D.Personalities and Jobs
