Seven Health Facts about Coffee
When you’re considering your morning coffee, here are some health facts to keep in mind:
1. Coffee Reduces Your Risk of Diabetes (糖尿病)
In a 2005 review of nine studies, researchers found that for those that drank four to six cups of coffee per day, versus only two or fewer, their risk for Type 2 diabetes decreased by almost 30 percent. The number decreased by 35 percent when people drank more than six cups per day. And if you’re picturing yourself running around the office with your eyes bugging out of your head, no worries because caffeinated and decaffeinated coffees provided much the same results.
2. Coffee Fights Free Radicals (自由基)
We often forget that coffee is actually a plant and like all plant foods, the coffee bean contains more than 1,000 naturally occurring substances called phytochemicals, which may help prevent disease. Many of these phytochemicals are antioxidants which protect the cells from damage from free radicals.
3. Coffee Improves Memory and Cognition
Researchers reported that volunteers who drank caffeinated coffee in the morning performed better than nondrinkers on tests that involved learning new information. Coffee can also improve cognitive function as we age. One study found that combining coffee with a sweet treat had an even bigger impact.
4. Coffee Can Increase Osteoporosis (骨质疏松)
It’s true that coffee can cause the body to excrete calcium in urine. We don’t want the body to rid itself of calcium because this can lead to osteoporosis. According to The Diet Channel, about five milligrams of calcium is lost per every six ounces of coffee consumed. But these calcium losses can be counter balanced with two tablespoons of milk or yogurt per cup of coffee.
5. Coffee Causes Wrinkles
Even though coffee has antioxidants, if you drink too much of it, it can cause wrinkling of the skin. This is a result of dehydration (脱水) which is the worst thing for your skin. So when you’re drinking that morning cup or two, make sure that you’re pairing it with water. Even better, add one tablespoon of chia seeds to your water and let them sit for 30 minutes. The chia seeds keep you even more hydrated than regular water.
6. Coffee Can Actually Cause Weight Gain
The blood sugar changes that a caffeine high produces can contribute enormously to a strong desire for it, according to iVillage. Coffee is also socially connected to food. For example, we pair coffee with dessert or that morning powdered doughnut. Additionally, when we crash from our caffeine high that’s when we reach for all sorts of fatty snacks to keep us going.
7. Conventional Coffee Is Laden with Pesticides (杀虫剂)
The coffee plant is one of the most heavily sprayed crops. It’s coated with chemicals, pesticides, and herbicides, nothing you’d want to be swallowing. If you do drink coffee, make sure that it’s the organic variety, free from assorted chemicals that leech into our ground water and can make us sick down the road.
If you switch to decaffeinated coffee, make sure the caffeine (咖啡因) is removed in a natural way without the use of chemicals to do it. Often times, conventional decaffeinated coffee has more chemicals than regular. If you want to decrease the risk of diabetes by 35%, you need to take at least _____ cups of coffee every day.
| A．seven | B．six | C．five | D．four |
If you are a heavy drinker of coffee, a far better way to avoid wrinkling of your skin is to drink water _____.
| A．less than usual | B．regularly | C．with sugar | D．with chia seeds |

| A．Adding two spoons of milk to a cup of coffee can prevent calcium losses. |
| B．Decaffeinated coffee has different effects from caffeinated coffee as to diabetes. |
| C．Many phytochemicals protect the cells from damage from free radicals. |

A “blogger” is a person who writes on an Internet website called a “blog”. The word “blog” is a short way of saying “web log”, or “personal website”. Anyone can start a blog, and they can write about anything they like．
There are millions of blogs on the Internet today. They provide news, information and ideas to the people who read them．They contain links to other websites．And they provide a place for people to write their ideas and react to the ideas of others．
A research company called Perseus has studied more than 3,000 web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year．
However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products．
At thesame time, some long-standing blogs have ended. Last week, blogging leader Dave Winer closed his free blog service “weblogs.com”． He said the site became too costly to continue. He started the blog four years ago, and thousands of people had written on it. They are now upset because they did not know that the site was closed．
One blog that is still going strong is called Rebecca’s Pocket．Rebecca Blood created the website in 1999. She wrote about the history of blogs on the site．That article led to a book called The Weblog Handbook．It has been translated into four languages so far．
Miss Blood says Rebecca’s Pocket gets about thirty thousand visitors a month．She writes about anything and everything —— politics, culture and movies. She recently provided medical advice． And she wrote about how to prevent people from being stolen from online bank accounts．The text is mainly written to _______．
| A．introduce an Internet website called “blog” |
| B．introduce a short way of saying “web log” |
| C．tell readers about blogs |
| D．tell readers how to write blogs |
From the text we can learn that blogs cover almost everything except _______．
| A．different ideas | B．medical advice |
| C．advertisements | D．account passwords |
Which of the following statements is NOT true according to the text?
| A．Politicians don’t use blogs at all． |
| B．A lot of bloggers no longer write or read blogs． |
| C．Those who like to use blogs are mostly teenage girls． |
| D．Dave Winer closed his “weblogs.com” because of the money shortage． |
The reason why Rebecca’s Pocket is still going strong is that _______．
| A．it was created by a woman |
| B．it is about the history of blogs |
| C．it provides useful information and advice |
| D．it has editions in atleast four different languages |
Short people, studies have shown , are more likely to have a stroke , suffer from high blood pressures and heart disease and be bullied in school .
Now, researchers report that short people—at least in the past—were also more likely to die at a younger age than their taller peers.
Their study, published in the Journal of Epidemiology (流行病学) and Community Health , found that short bones have something to do with short life for more than 1,000 years. The conclusion was based on 490 sets of adult skeletal(骨架) remains from an archaeological(考古学的) site in northeastern England , YC dating from the 9th century to about 1850 .
About 55% of men and 73% of women died before the age of 45, and 39% of men and 56% of women died before age 30. The risk of death before age 30 declined as bone length increased.
“This study provides evidence from an archaeological sample that long bone length is connected with age at death—those with smaller bones tend to die younger,” according to Dr. D.J. Gunnell of the university of Bristol in the UK and colleagues .
While it is not clear why short stature(身材) might be linked to earlier death , the researchers point out that height is an indicator of childhood nutrition, which may have long-lasting effect on health .
“Mechanism (身体结构) for height-mortality(死亡) associations in the past may differ from those today , for example , short stature may have increased the risk of death in childbirth and this may explain the higher risk of premature(未成熟的) mortality in women,” Gunnell and colleagues write .
“However, short bones, it would appear, have always been a marker of a short life,” the authors conclude.The title of the passage should be.
| A．Short people and their taller peers |
| B．Men and women |
| C．Short stature and short life |
| D．Long life and short life |
“An indicator” in Paragraph 6 means.
| A．a study | B．a marker | C．a risk | D．an age |
Which of the following statements is Not true according to the passage?
| A．People with smaller bones were more likely to die younger. |
| B．Women were more likely to die at a young age. |
| C．Short-stature women bear higher risk of death in giving birth to babies. |
| D．Most people were more likely to die at the age of 30 in the past. |
Short stature may be caused by.
| A．less childhood nutrition | B．heart disease |
| C．some illnesses | D．high blood pressure |
The topic in this passage is probably connected with
| A．space medicine | B．sports medicine |
| C．social medicine | D．industrial medicine |
The blockbuster film Titanic has brought millions of dollars and thousands of people to the theaters and continues to touch people today in their homes. Why is this film so successful? It is a combination of many different things. Among these are many different elements. Looking at some of these elements will show how the director and others involved were able to create an emotionally charged movie that appealed to millions.
The film uses one thematic(主题的) element called - The Truth of Human Nature. The two main characters seem to represent noble people. Most of the other characters in the film are shown as non-tolerant, rude and cold-hearted people. The element of focusing on the two main characters' love and emotion seems symbolic of an ideal state.
There are also social problems addressed. This is done in a few different ways. The most noticeable way is that the lower class people remain locked in the basement as the ship goes down. Throughout Titanic, the lighting is very important. The poor, lower class people are always shown in very warm-coloured light that gives them a sense of life and happiness. On the other hand, the rich, upper class are always shown in a flat light portraying the feeling of hardness and coldness. By using these techniques, they show the issue of class segregation(种族隔离), and they create stereotypes. The main characters are able to break free of these stereotypes and be together. This is the solution to the segregation problem.
As you can see, Titanic took a lot of thinking and preparation to film in a manner that would create emotion and bring to the surface the issues and story of the great ship.The underlined word “blockbuster” in the first paragraph probably means “________”．
| A．something very successful |
| B．a highly explosive bomb |
| C．something worth a lot of money |
| D．a touching story |
In Titanic, the scene of the lower class people remaining locked in the basement as the ship goes down is used to ________.
| A．criticize non-tolerant and cold-hearted rich people |
| B．enlarge the scene of the film |
| C．make the film more attractive |
| D．emphasize the condition of the poor at that time |
Why were different colours of light used in the film Titanic? ________
| A．They were used to show the difference between the rich and the poor. |
| B．The director was determined to achieve good visual effect. |
| C．The social status was represented by the color of light in the past. |
| D．The use of light was the main technique the director made use of. |
What can we infer from the passage? _________
| A．The segregation problem in the society can be solved by using the light. |
| B．Though love is the main theme of Titanic, it also reflects some social problems. |
| C．Because of the director's talents, the film Titanic achieved great success. |
| D．In the film Titanic there are two characters altogether. |

Sir,
Just over six months ago, I saw an advertisement in the Morning Mail for a set of the complete works of William Shakespeare. Your company, Cosmo books Ltd., offered this set (eight books of plays and two books of poetry) at what was claimed to be a ‘remarkable’ price: fifteen pounds and fifty pence, including postage and packing. I had wanted a set of Shakespeare’s plays and poems for some time, and these books, in red imitation leather, looked particularly attractive; so I sent for them.
Two weeks later, the books arrived, together with a set of the complete works of Charles Dickens which I had not ordered. So I returned the Dickens books to you, with a cheque for fifteen pounds and fifty pence for the works of Shakespeare. Two more weeks passed. Then there arrived on my door step a second set of the works of Shakespeare, the same set of novels by Dickens and a six book set of the plays of Moliere, in French. Since I do not read French, these were of no use to me at all. However, I could not afford to post all these books back to you, so I wrote to you at the end of August of last year, instructing you to come and collect all the books that I did not want, and asking you not to send any other books until further notice.
You did not reply to that letter. Instead you sent me a bill for forty two pounds, and a set of the plays of Schiller, in German. Since then, a new set of books has arrived every two weeks, the works of Goethe, the poems of Milton, the plays of Strindberg; I hardly know what I have. The books are still all in their boxes, in the garage, and my car has to stand in the rain outside.
I have no room for any more books, and even if I read from now until the Last Judgment, I should not finish reading all the books that you have sent me.
Please send no more books, send no more bills, send no more angry letters demanding payment. Just send one large lorry and take all the books away, leaving me only with the one set of the complete works of Shakespeare for which I have paid.
Yours faithfully,
SIMON WALKERSimon Walker wrote the letter to ________

You’re rushing to work and a man ahead of you collapses on the sidewalk. Do you stop to help? In a study of by-standers, it was found that some people avert their gaze and keep on walking rather than stop and get involved.
“There is a tendency to decide that no action is needed.” says a psychologist. “The first thoughts that pop into your mind often keep you from offering help. In order to take action, you have to work against them.” Here are some common thoughts that might prevent you from helping.
● Why should I be the one? I’m probably not the most competent（有能力的） person in this crowd. You might think someone older or with more medical knowledge should offer assistance.
● What if he doesn’t really need my help? The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others.
● No one else looks concerned- this must not be a problem. We can follow the people around us, but most people tend to hold back their emotions in public.
“If you spot trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on,” says the psychologist. “Then retry to involve other people; you don’t have to take on the entire responsibility of being helpful. Sometimes it’s just a matter of turning to the person next to you and saying, ‘It looks like we should do something.’ Or asking someone if an ambulance has been called and, if not, to call for one. Once you take action, most people will follow you.”Which is NOT the common thought that stops you from helping others?
| A．I’m not the very person capable of setting the problem. |
| B．It looks like we should do something. |
| C．It must not be a problem as no one else is concerned. |
| D．He doesn’t really need my help. |
According to a study of by-standers, what will some people do when a man ahead falls down on the sidewalk?
| A．They will call for help and then walk away. |
| B．They will stop and offer help. |
| C．They will turn away their eyes and go on walking. |
| D．They will laugh at him. |
We learn from the last paragraph that if we spot trouble, ．
| A．we should call the ambulance as soon as we can. |
| B．we should take on the whole responsibility and do something alone. |
| C．we should stop and evaluate the situation and try to make other people follow. |
| D．we should turn to other people and ask them to take on the responsibility |
In order to offer others your timely help, you need to．
| A．ask others for help and call the police |
| B．get along well with the passers-by who spot the trouble |
| C．go directly to the police station |
| D．work against the first thoughts that prevent you offering help |
The main purpose of the text is to tell readers．
| A．to give others a hand |
| B．to be more competent |
| C．not to risk looking foolish |
| D．to stop and evaluate the situation |
