The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically（身体上）.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.From Paragraph 1, we learn that ________.
| A．diet products fail to bring out people’s potential |
| B．people are fed up with diet products |
| C．people have difficulty in choosing diet products |
| D．diet products are misleading people |
One psychological effect of diet products is that people tend to _____.
| A．hesitate before they enjoy diet foods |
| B．pay attention to their own eating habits |
| C．watch their weight rather than their diet |
| D．try out a variety of diet foods |
In Paragraph 3, “gain comes without pain” probably means ______.
| A．losing weight is effortless |
| B．diet products bring no pain |
| C．it costs a lot to lose weight |
| D．diet products are free from calories |
Diet products indirectly harm people physically because such products ______.
| A．lack basic nutrients | B．are over-consumed |
| C．are short of chemicals | D．provide too much energy |
A study involving 8,500 teenagers from all social backgrounds found that most of them are ignorant when it comes to money. The findings, the first in a series of reports from NatWest that has started a five-year research project into teenagers and money, arc particularly worrying as this generation of young people is likely to be burdened with greater debts man any before.
University tuition fees (学费) are currently capped at £3,000 annually, but this will be reviewed next year and the Government is under enormous pressure to raise the ceiling.
In the research, the teenagers were presented with die terms of four different loans but 76 per cent failed to identify the cheapest. The young people also predicted that they would be earning on average £ 31.000 by the age of 25, although the average salary for those aged 22 to 29 is just £ 17,815. The teenagers expected to be in debt when they finished university or training, although half said that they assumed the debts would be less than £ 10.000. Average debts for graduates are £ 12，363.
Stephen Moir, head of community investment at the Royal Bank of Scotland Group which owns NatWest, said. "The more exposed young people are to financial issues, and the younger they become aware of them, the more likely they arc to become responsible, forward-planning adults who manage their finances confidently and effectively."
Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs. They have just introduced new lessons in how to manage debts. Nikki Fairweathcr. aged 15. from St Helens, said that she had benefited from lessons on personal finance, but admitted that she still had a lot to learn about money.
1. Which of the following can be found from the five-year research project?
A. Students understand personal finances differently.
B. University tuition fees in England have been rising.

D. The students' payback ability has become a major issue.
2. The phrase "to raise the ceiling" in paragraph 2 probably means "______".
A. to raise the student loans B. to improve the school facilities
C. to increase the upper limit of the tuition D. to lift the school building roofs
3. According to Stephen Moir, students_______.
A. are too young 10 be exposed 10 financial issues
B. should learn 10 manage their finances well
C- should maintain a positive attitude when facing loans
D. benefit a lot from lessons on personal finance
4. What can we learn from the passage?
A. Many British teenagers do not know money matters well
B. Teenagers in Britain are heavily burdened with debts.
C. Financial planning is a required course at college.
D. Young people should become responsible adults.
This was no ordinary class. The students who came together were all science or engineering professors at Cornell University. They had interrupted their research to accept an invitation to take part in an unusual experiment: “an interesting week of poetry.” This class was part of a study to answer the questions: Why is science difficult for many non-science students? What can teachers learn about teaching if they take a class that is not in their field?
The students in the poetry class listened to lectures and took notes. They had reading tasks and had to write three short papers. All students noticed one thing – the importance of spoken words. In science and engineering classes, the instructors put tables and drawings on the blackboard. But in this poetry class, the instructors just talked. They didn’t write anything on the board.
The scientists and engineers noticed one similarity between science and poetry. In both subjects, students need to find layers (层次) of meaning . Some layers are simple, clean, and on the surface; other layers are deeper and more difficult. This search for different levels of meaning doesn’t happen much in undergraduate(本科) science classes, but it is important later, in graduate school. And it is always important in humanities(人文科学).
Both the poetry instructors and their students learned something about teaching from this experience. One poetry instructor, for example, now sees the importance of using informative as he teaches. Most of the scientists agreed on several points. First, humanities classes might help science students to see patterns and decide which information is important. Second, the poetry class was fun. One engineer decided, “We need to change the way we teach engineering to make to make it an enjoyable experience for students.”
But perhaps the most important result of the experience was this; All of the professors began to think about how they teach and how they cam teach better. What do we know about this unusual class?
| A．The teachers did lots of writing on the board |
| B．The teacher were invited to attend several lectures. |
| C．The student were professors from a university |
| D．The students were studying science and humanities. |
The experiment was designed to find out
| A．how to teach the students in the science class |
| B．whether poetry is difficult for science students |
| C．what to be taught in the humanities class |
| D．why many humanities students find science hard. |
Finding levels of meaning is .
| A．important for graduate students in humanities |
| B．difficult for graduate students in humanities |
| C．common for undergraduate students in science |
| D．easy for undergraduate students in science. |
What did the science professors learn after the experiment?
| A．They should change the way they teach |
| B．A poem could be explained in clear definitions. |
| C．A poetry class could be more informative. |
| D．Their teaching was an enjoyable experience. |
Do you know of anyone who uses the truth to deceive (欺骗)? When someone tells you something that is true, but leaves out important in formation that should be included, he can give you a false picture.
For example, some might say, “I just won a hundred dollars on the lottery (彩票). It was great. I took that dollar ticket back to the store and turned it in for on e hundred dollars!”
This guy’s a winner, right? Maybe, maybe not. We then discover that he bought $200 worth of tickets, and only on e was a winner. He’s really a big loser!
He didn’t say anything that was false, but he left out important information on purpose. That’s called a half-truth. Half-truths are not technically lies, but they are just as dishonest.
Some politicians often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents(对手) says, “During Governor Smith’s term, the state lost one million jobs!” that’s true. However, and honest statement would have been, “During Governor Smith’s term, the state had a net gain of two million jobs.”
Advertisers(广告商) will sometimes use half-truths. It’s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, “Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.
This kind of deception happens too of often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
How much did the lottery winner lose?
| A．One hundred dollars. | B．Two hundred dollars. |
| C．Three hundred dollars. | D．Four hundred dollars. |
We may infer that the author believes people should _______.
| A．buy lottery tickets |
| B．make use of half-truths |
| C．not take anything at face value |
| D．not trust the Yucky Company |
What do the underline words “net gain” in Paragraph 5 mean?
| A．final increase | B．big advantage |
| C．large share | D．total saving |
What can we know from the example of the Yucky Pill advertisement?
| A． False statements are easy to see through. |
| B． Half-truths are often used to mislead people. |
| C． Doctors like to act in advertisements. |
| D． Advertisements are based on facts. |
You’re sitting on the train home and the person opposite you yawns(打哈欠). Suddenly, you’re yawning with him, though you’re not tired.
This phenomenon confused scientists for years until a recent study found that people tend to sympathize with fellow humans. Supporting this claim was the discovery that those children who were unable to form normal emotional ties with others did not experience contagious(有感染力的) yawning, which showed that humans communicate regularly with out words.
Hugo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness and sadness can spread like the common cold. According to Critechley, our mind and body are in constant exchange about how we’re feeling. “Emotions are closely linked with states of internal(内部的) responses,” he explained. “ There are also more visible changes in our gestures and facial expression. When we’re in a group, these signals can spread to another person. For example, there’s the obvious tendency to smile when smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a change in our heart rate and blood pressure.
Hugo Critchley further explained, “Our bodies synchronies and when we like the other person, we ever copy his behavior. Next time you chat with a friend, take note of how you’re sitting— it’s pretty likely that you will be the same. Scientists believe it’s our way of telling each other that we’re partners. Through body language, humans give each other very subtle(微妙的) but clear signals that show emotions.”
So, what lessons can we learn from this? “ Spend time with happy people— otherwise your health could suffer,” said Critchley.” When we’re sad, our body goes into fight or flight mode. But when we’re happy, our body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and it affects everyone around us.” According to Hugo Critchley, ________.
| A．emotions are as visible as facial expressions |
| B．we yawn more frequently when we have a cold |
| C．emotions are connected with states of internal responses |
| D．the change of blood pressure is not linked with the change of emotions. |
The underlined word “synchronies” in Paragraph 4 means “_____”.
| A．move slowly | B．change rapidly | C．relax temporarily | D．respond accordingly |
From the passage we can learn ________.
| A．sadness is as contagious as happiness |
| B．anger is less contagious than friendliness |
| C．surprise is more contagious than smile |
| D．surprise is the most contagious among emotions |
Which of the following statements is true according to the passage?
| A．Emotions have delicate influence on fellow humans. |
| B．Children like copying the actions of the fellow humans. |
| C．Scientists are still confused about contagious yawning |
| D．People tend to communicate more with body language. |
Michael Fish may soon be replaced as a weather forecaster by something truly fishier---the shark(鲨鱼).
Research by a British biology student suggests that sharks could be used to predict storms.
Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure.
If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.
Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.
She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University.
Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks(黑边鳍真鲨) off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”
“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.”
It has been discovered that a shark senses pressure using hair cells in its balance system.
At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.
In Aberdeen, she was able to study the effects of tidal(潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic(模拟) oceanic pressure changes caused by weather fronts.
She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.
The passage is most probably taken from _____.
| A．a short-story collection |
