Last summer, when Amanda R of Anaheim Hills, California, was running on a cross-country course with her team, she blacked out. “I got really dizzy,” she says. “I was out for a few minutes.” At first, Amanda thought she was just tired and didn’t think she had a health problem. She did go to the emergency room, where she was fine after tests, but she fainted (昏厥) again several days later as she was talking with her coach. Another doctor guessed that Amanda had blacked out “because we were in heat so much with not enough water and not enough of the right kind of foods”.
Teens often don’t want to stop and take a break or don’t notice when they start to feel bad, doctors say. However, paying attention if you’re not feeling well is important, as Amanda learned.
As a result, Amanda has changed her habits. “I drink a lot more water,” she says. “And put more salt in my diet. I’m eating more balanced meals.” Amanda advises teen athletes to trust their coaches and speak up when they’re not feeling well. “And recognize the difference between when you’re tired and when there’s something really wrong.”
Some people － up to 3 percent of the population － sweat too much, even in cold weather. The condition, called hyperhidrosis (多汗), can affect many parts and it often runs in families － hands down from generation to generation. Too much sweating over the whole body could be a symptom of another medical condition. Doctors aren’t sure what causes hyperhidrosis, but using special medications or other treatments can help.What caused the happening mentioned in the passage during Amanda’s running?
| A．She couldn’t breathe in enough air in the race. |
| B．She didn’t eat anything before the race. |
| C．She had been running all summer without a rest. |
| D．She neither drank enough water nor ate enough of the right kind of foods. |
What can we infer from Paragraph 4?
| A．There is no need to worry when sweating too much, even in cold weather. |
| B．Hyperhidrosis may have a bad effect on your health. |
| C．Doctors have discovered why people get hyperhidrosis. |
| D．Hyperhidrosis is a serious disease and no treatment can help. |
The purpose of writing this passage is to____________.
| A．tell teens the proper ways to take exercise in summer. |
| B．tell teens not to run in hot summer. |
| C．tell teens to pay attention to hyperhidrosis in the summer exercise |
| D．tell teens how to keep healthy. |
For all dinner tables, a glass of milk seems to be a must. At least it was when I was growing up. It is widely believed that milk is a must in building strong bones and teeth. There’s no doubt that dairy products, especially milk, are high in protein and calcium, and Vitamin D and Vitamin A are added to most milk products.
While it’s well known that our bones need calcium, some studies suggest that high calcium intake doesn’t necessarily lower a person’s risk for fractures（骨折）. A Harvard study found that people who drank two or more glasses of milk had no greater protection from breaking a bone than those who drank a glass or less a week.
There is no doubt that we need calcium. Some anti-dairy supporters claim dairy products can lead to heart disease. Much of this claim is based on high-fat dairy products, like cheese and cream, which may indeed lead to some health problems. Some studies have linked high milk intakes with a risk of prostate cancer; this seems also to be caused by high-fat dairy products, but not by dairy products in general.
Although milk has always been regarded as the most important thing we need for our bones, one of the most important things in strengthening bones and reducing the risk of osteoporosis（骨质疏松）is weight-bearing exercise, such as jogging, walking, and weight lifting.
Perhaps we should think of dairy products as less like a nutrient and more like a food. If you like it, eat it. If not, find something else to eat. Some claims may not be completely true. When I eat cream, I’m not thinking about calcium, protein, or any such thing. I’m thinking it is delicious.What is the best title for this passage?

One would have to be a fool to overlook (忽视)the importance of using positive(积极的) thinking for you rather than allowing negative thinking to work against you. In recent years, research in psychopharmacology (精神药理学) has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything. Researchers found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a decline of hormone (荷尔蒙) and shuts down the immune (免疫的) system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by literally forcing yourself to be positive (faking it, so to speak), it will become contagious (会传播的) and the positive thoughts will generate nice little chemicals and good feelings which will reinforce the positive thoughts.
For example, if you force yourself to smile or laugh, even when you don't feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate (导致)thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude.
It's often been said that in the land of the blind, the one-eyed man is king. And in the office of militant (好战) negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This vital key to success is totally within your control. Use it.We can infer from the passage that .
| A．positive thinking can cure you of your diseases |
| B．positive thinking can easily be generated by anyone |
| C．a decline of hormone may cause you to be depressed |
| D．a specific chemical reaction is the cause of negative thinking |
According to the passage, which of the following is true?
| A．Feeling and thoughts can generate each other. |
| B．It's easier to control thoughts than to control feelings. |

| A．control your feeling to what is happening to you |
| B．be king in your office |
| C．pay no attention to what is going on around you |
| D．take positive attitude in the office of militant negativism |
The best title to the passage is .

Few people realize that there is a big difference between formal English and informal English. Formal English is used for most writing, and often in public speaking and formal meetings. It pays close attention to grammar rules, because if we use proper grammar, our meaning is often more precise. Also, on important occasions, we do not want to appear uneducated or to offend (冒犯) others, so we are very careful about how we speak. Informal English is used in speaking or writing to our friends and family. It often does not pay such close attention to grammar rules, because when we speak or write to them, we want our words to flow quickly. Also, with our friends and family, we are usually not so worried about appearing uneducated or about offending them by how we write or speak.
A big difference between formal and informal English is the use of contractions. A contraction is where we make a word shorter or where we put two words together and take away some of the letters. For example, instead of saying “do not”, many people say “don’t”. Using contractions in our speech is fine because it sounds natural, especially when we speak to our friends. In formal writing, however, contractions are usually avoided because people might think that you have made a mistake, or that you do not know proper grammar.
In the same way we might make words shorter, in informal English we often make sentences shorter as well. For example, if someone asks you your name, you will likely answer with one word: your first name. However, in formal English we usually use complete sentences. For example, we might write “My name is John”. In most speaking, we may not need to use every word in a sentence because the person we are speaking to will probably still understand us. In most writing, however, every word in a sentence must be written out in order to make sure that we can be understood.When we use formal English, _______.
| A．we will offend others |
| B．we will appear educated on important occasions |
| C．we needn’t pay more attention to grammar rules |
| D．we can express ourselves more directly and more quickly |
What’s the meaning of the underlined word “precise”?
| A．clear | B．direct | C．puzzling | D．simple |
Contractions are best used when we are _______.
| A．speaking at a formal meeting | B．speaking in public |
| C．speaking to our friends | D．writing an application (申请) letter |
In speaking, we do not always use complete sentences because ______.
| A．we do not care about grammar | B．we do not want to sound stupid |
| C．we can still be understood | D．we don’t want to waste time |
Why do some people flush when they drink alcohol? This effect is a common reaction to alcohol among East Asians. It affects about 36 percent of Japanese, Chinese and Koreans.
For many, even a small amount of alcohol can cause unpleasant effects. Most commonly, their face, neck and sometimes their whole body turn red. People might also feel uncomfortable and sick to their stomach. They might experience a burning sensation, increased heart rate, shortness of breath and headaches.
The cause is a genetic difference that they are born with called an ALDH2 deficiency (缺乏). It prevents their bodies from treating alcohol the way other people do. But the effects might be more serious than just a red face. Researchers warn of a link between this condition and an increased risk of cancer of the esophagus (食道) from drinking alcohol.
The more alcohol people with this deficiency drink, the greater their risk is. In Japan and South Korea, for example, many people have the deficiency but still drink heavily. Researchers found that these drinkers develop a form of esophageal cancer six to ten times more often than those without the deficiency.
Esophageal cancer is one of the deadliest cancers. It can be treated when found early, but once it grows the chances of survival drop sharply. The researchers estimate that at least five hundred forty million people have the deficiency, about eight percent of the world’s population.
Philip Brooks is a researcher at the National Institute in the United States. He says it is important to educate people about the link between the alcohol flushing effect and esophageal cancer. He says doctors should ask East Asian patients about their experiences with facial flushing after drinking alcohol. Those with a history of it should be advised to limit their alcohol use. They should also be warned that cigarette smoking works with the alcohol in a way that further increases the risk of esophageal cancer.The underlined word “flush” in Paragraph 1 probably means “_________”.
| A．walk unsteadily | B．turn red in the face |
| C．appear unpleasant | D．talk more than usual |
The second paragraph is mainly about _________.
| A．the cause of the effects of alcohol |
| B．Asians and alcohol |

We can infer from the passage that _________.
| A．about 36 percent of Japanese, Chinese and Koreans are heavy drinkers |
| B．the ALDH2 deficiency may be passed on from generation to generation |
| C．unpleasant effects occur only when people with this deficiency drink a lot |
| D．only some East Asians have the ALDH2 deficiency |
Esophageal cancer is one of the deadliest cancers because _________.
| A．it can’t be treated at all |
| B．it is hard to be discovered early |
| C．it is hard to cure once it has developed |
