Fever has usually been regarded as a threat to health.However,no one has actually proved that fever is dangerous.This fact attracted the attention of Matthew J.Kluger.Imagining that fever might not be as harmful as it had been supposed,Kluger set up a series of experiments with lizards(蜥蜴).
What Kluger and his team did his team did in their first experiment was simple.They put some lizards in a sand-box,one end of which was heated to 44℃,while the other was at a room temperature.It was found that the lizards moved form one part of the box to the other in order to keep a constant temperature of about 38℃.Having shown that normal lizards regulate(调节) their own temperature,Kuger,in a second experiment,then set out to show that lizards,like most other animals,develop fever when infected.This was done by making lizards infected with bacteria (细菌) that were known to cause disease.As the team expected,the infected lizards remained longer in the heated part of the box,until they had raised their body temperatures to two or three degrees above normal.In other words,the sick lizards gave themselves fever.
In a third experiment,the team observed the effect of temperature on the survival of the lizards.One group of infected lizards was given a fever - suppressing(退烧) drug.The other group was given no drug and ran a fever,that is to say,they kept a highter temperature for four or five days before seeking a cooler environment.The results were impressive.Of those which raised their body temperature,all but one remained alive.Of those given the fever - suppressing drug,more than half died.Similar results have since been produced in other animals.For example,infeced fish swim to warmer water,and will die if not allowed to do so.
An important conclusion can be drawn from these experiments.As Kluger points out,lizards have been on earth for hundreds of millions of years.It is reasonable to suppose that a response that is so old has been kept by nature for some purpose.It would appear, therefore, that fever does not make disease worse.Rather it its part of the mechanism(机能) by which infection is controlled.

The day was Thankful Thursday. It's a weekly tradition that my two little girls and I began years ago. Thursday has become our day to go out and make a positive contribution. On this particular Thursday, we had no idea exactly what we were going to do. At noon, I drove to a McDonald’s with my daughters because they kept complaining that they hadn’t had enough to eat at breakfast. There we saw some homeless people in the street and we bought lunch for them.
We were about to complete when we found a small woman standing at the corner, asking for change. We handed her some food, and then started to head home. Suddenly from the mirror of the car, I saw the woman waving at us, so I had to turn around and stopped where the small woman stood. She walked to our car, and said, "Thank you, lady! No one has ever done anything like this for me before." I replied, "Well, I'm glad that we were the first." Feeling uneasy, and wanting to move the conversation along, I asked, "So, when do you think you'll eat your lunch?"
She just looked at me with her huge, tired brown eyes and said, "Oh honey, I'm not going to eat this lunch." I was confused, but before I could say anything, she continued. "You see, I have a little girl of my own at home and she just loves McDonald's, but I can never buy it for her because I just don't have the money. But you know what…tonight she is going to have McDonald's!"
I don't know if the kids noticed the tears in my eyes. So many times I had questioned whether our Acts of Kindness were too small to have effect on those poor people. Yet at that moment, I realized the truth of Mother Teresa's words: "We cannot do great things — only small things with great love."
According to this passage, the small woman was ______.
| A．too happy to stand at the corner |
| B．too eager to ask for more food |

| B．The author would stop doing her acts of kindness to the poor. |
| C．The author’s daughters found their mother cried at the end of the day. |
| D．The author’s daughters would make friends with the woman’s daughter. |
What would be the best title of the passage?
| A．No Pains No Gains |

In a book called Magnificent Obsession, by Lloyd C. Douglas, a description is given of people helping others but doing it secretly. When difficult problems worried an individual, friends nearby would meet to discuss possible solution without the individual knowing their actions. When a solution was agreed upon, one or two of the friends would carry out the plan and solve the problem secretly , to the great delight of the worried individual. The helpers would stand by privately, content with their success. No reward was given to the problem solvers, not even a sincere “thank you”, because they were never known.
This concept is popular today but in a different way. The phrase “pay it forward” is now used when one person helps another. However, the person helped may not be able to repay the person or group that helped them. So rather than return the favor to their helpers, they are supposed to help someone else in the future, which means they pay it forward. It is a sense of responsibility which makes us want to give back in equal measure to the one who has helped us. But , in this case, the responsibility turns to helping someone in the future.
Suppose your elderly grandmother pays part of your schooling. She may tell you there is no need to repay her because it is a gift from someone who loves you very much. Nothing would please her more than to have you use her money to get a good education.
You may never be able to repay her for such a gift. However, she not only gave you some money , but she provided you with an example that you should also help other people who need it.
People with serious needs are everywhere. Many are children who need better clothes, more books and even better schools. Some are elderly people who can’t afford their medicine or a doctor’s care. Consider how you can “pay it forward” rather than pay money back to your grandmother.
The underlined word “pay it forward” means ____________________.
| A．to repay someone who has helped you |
| B．to pay someone else who needs help |
| C．to help someone who has helped you |
| D．to help someone else who needs help |
What does the writer suggest with the example of “your elderly grandmother”?

It may help you to know that there is no such thing as a perfect speech．At some point in every speech, every speaker says something that is not understood exactly as he has planned．Fortunately, the moments are usually not obvious to the listeners. Why? Because the listeners do not know what the speaker plans to say. They hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser．When such moments occur, don’t worry about them, Just continue as if nothing happened．
Even if you do make an obvious mistake during a speech, that don’t really matter. If you have ever listened to Martin Luther King’s famous speech – “ I have a dream”, you may notice that he stumble（结巴）his words twice during the speech．Most likely, however, you don’t remember．Why? Because you were fixing your attention on is message rather than on his way of speech-making. People care a lot about making mistakes in a speech because they regard speech-making as a kind of performance rather than as an act of communication. They feel the listeners are like judges in an ice-skating competition．But, in fact, the listeners are not looking for a perfect performer. They are looking for a well-thought-out speech that express the speaker’s ideas clearly and directly．Sometimes a mistake or two can actually increase a speakers’ attractiveness by making him more human．
As you work on your speech, don’t worry about being imperfect．Once you free your mind of this, you will find it much easier to give your speech freely．
The underlined part in the first paragraph means that no one will ___________．
| A．be smarter than you | B．notice your mistakes |
| C．do better than you | D．know what you are talking about |

| A．your attention is on the content |
| B．you don’t fully understand the speech |
| C．you don’t know what the speaker plans to say |
| D．you find the way of speech-making more important |
It can be inferred from the passage that ___________．
| A．giving a speech is like giving a performance |
| B．one to two mistakes in a speech may not be bad |
| C．the listeners should pay more attention to how a speech is made |
| D．the more mistakes a speaker makes, the more attractive he will be |
What would be the best title of the passage?
| A．How to Be a Perfect Speaker |
| B．How to Make a Perfect Speech |
| C．Don’t Expect a Perfect Speech |
| D．Don’t Expect Mistakes in a Speech |
It is a matter of common observation that although incomes keep going up over the years，people never seem to become much better off! Prices are rising continuously．The condition is termed(称作) one kind 0f inflation, the money supply is becoming inflated so that each unit of it becomes less valuable．People have got used in recent years to higher and higher rates of inflation．
What could be bought ten years ago for one dollar now costs well over two dollars. It seems that this rate of inflation is tending to rise rather than to fall．If in the real world our money incomes go up at the same rate as prices，one might think that inflation does not matter．But it does when money is losing value，it lacks one of the qualities of a good money---stability (稳定) of value．It is no longer acceptable as a store of value；and it becomes an unsuitable standard of deferred(延期) payments．Nobody wants to hold a wasting possession，so people try to get rid of money as quickly as possible. Inflation therefore stimulates people spending，and prevents people from saving.
What does inflation mean?
| A．People’s money becomes more valuable |
| B．The problem of employment will be solved． |
| C．It’s easier for people to find better paying jobs． |
| D．Money keeps losing its value． |

| C．hold on to money as a dependable possession |
| D．spend money as soon as possible |
Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation（感觉） of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist John A. Bargh.
Psychologists have known that one person’s perception（感知） of another’s “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother” rather than one made of wire, even when the wire “mother” carried a food bottle. Harlow’s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.
Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.
To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses（假设）, handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.
“We are grounded in our physical experiences even when we think abstractly,” says Bargh.
According to Paragraph 1, a person’s emotion may be affected by ______.
| A．the visitors to his office | B．the psychology lessons he has |
| C．his physical feeling of coldness | D．the things he has bought online |
The author mentions Harlow’s experiment to show that ______.
| A．adults should develop social skills | B．babies need warm physical contact |
| C．caregivers should be healthy adults | D．monkeys have social relationships |
In Bargh’s experiment, the students were asked to ______.
| A．evaluate someone’s personality | B．write down their hypotheses |
| C．fill out a personal information form | |
| D．hold coffee and cold drink alternatively |
We can infer from the passage that ______.
| A．abstract thinking does not come from physical experiences |
| B．feelings of warmth and coldness are studied worldwide |
| C．physical temperature affects how we see others |
| D．capable persons are often cold to others |
What would be the best title for the passage?
| A．Drinking for Better Social Relationships |
| B．Experiments of Personality Evaluation |
| C．Developing Better Drinking Habits |
