1. One of the greatest problems for those settlers in Nebraska in the last quarter of the previous century was fuel. Little of the state was forested when the first settlers arrived and it is probable that by 1880, only about one-third of the originally forested area remained, down to a mere 1 percent of the state’s 77,000 square miles. Some solution had to be found. Somewhat improbably, the buffalo provided the answer. Soon, collecting them became a way of life for the settlers’ children who would pick them up on their way to and from school, or take part in competitions designed to counteract their natural reluctance. Which of the following statements is NOT true ?
A. Nebraska was not a densely-forested state even before the settlers arrived B. The children enjoyed collecting the buffalo chips. C. The children spent some time collecting the chips D. Buffalo chips were satisfactory as a fuel.
2. Eating in space is different from eating on earth. The food that astronauts carry with them does not look like the food you eat. Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the spaceship the astronaut puts the water back. He “shoots” hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag. Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There are no crumbs. Crumbs would float around the spaceship and get in the way. Meat and cake often come in bite-sized pieces. Astronauts can’t drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth. Eating in space is not easy. Astronauts must learn to eat this way. The story does not say this, but from what we have read, we can tell that ___.
A. you get much hungrier in space than you do B. you can’t have water to drink in a spaceship C. astronauts must learn many new and different things D. you can’t eat anything in a spaceship
3. I wish I ___ ill yesterday; I could have gone with you. A. was not B. were not C. have not been D. had not been
4. I don’t know where ___ going.
A. will she B. she will C. is she D. she is
5. Last week a rare stamp ___at a price of 6,000 dollars.

6. In ancient times wealth was measured and exchanged in things that could be touched: food, tools, and precious metals and stones. Then the barter system was replaced by coins, which still had real value since they were pieces of rare metal. Coins were followed by fiat money, paper notes that have value only because everyone agrees to accept them.Today electronic monetary systems are gradually being introduced that will transform money into even less tangible forms, reducing it to a series of “bits and bytes”, or units of computerized information, going between machines at the speed of light. Already, electronic fund transfer allows money to be instantly sent and received by different banks, companies, and countries through computers and telecommunications devices. Which of the following statements about computerized monetary systems is NOT supported by the passage?
A. They promote international trade. B. They allow very rapid money transfers C. They are still limited to small transactions (交易) D. They are dependent on good telecommunications systems.
7. Researchers have found that REM (rapid eye movement) sleep is important to human beings. This type of sleep generally occurs four or five times during one night of sleep lasting five minutes to forty minutes for each occurrence. The deeper a person’s sleep becomes, the longer the periods of rapid eye movement. There are physical changes in the body to show that a person has changed from NREM (non-rapid eye movement) to REM sleep. Breathing becomes faster, the heart rate increases, and, as the name implies, the eyes begin to move quickly. Accompanying these physical changes in the body is a very important characteristic of REM sleep. It is during REM sleep that a person dreams. Which of the following is the best title of the article?
A. REM Sleep B. Two Types of Sleep C. Sleepers D. What Happens to Sleepers
8. Her dog ran out of the yard ___ the old lady opened the gate.

10. The water we drink and use is running short in the world. We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field. Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring. But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt. This process is called desalinization, and it is already in use in many parts of the world. The following tells us how to reuse the used water. What is the right title of the passage?
A. How to reuse the water B. put chemicals in the water C. Pipe the water to the users D. to pipe the used water to be purified to a factory
