Question 24 to 27 are based on the following passage.

Scientists can learn about man by studying animals, such as mice, rats and monkeys. The scientists in a laboratory areexperimenting on mice and they are studying the relationship between diet and health.

In this experiment, the scientists are studying the relationship between the amount of food the mice can eat and theirhealth. The mice are in three groups. All these groups are receiving the same healthy diet. But the amount of food that eachgroup is receiving is different. The first group is eating one cup of food each day, the second two cups, and the third threecups.

After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group arethinner than normal mice but they are more active. Most of the day, they are running, playing with one another, and using theequipment in their cages. Also, they are living longer. Mice usually live for two years, while most of the mice in this groupare still alive after three years.

The second group of mice is of normal weight. They are healthy, too. They are active, but not as active as the thinnermice. But they are only living about two years.

The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating orsleeping. They are not active. These mice are living longer than the scientists thought —about a year and a half, but they arenot healthy. The are sick more often than the other two groups.

24. The first group is the thinnest mainly because__________

A.they run and play all day long

B.they eat only one cup of food a day

D.they are bored with the kind of food in the cup

How long do normal mice live according to the passage？A.about one year

B.about a year and a half

D.about two years

E.about three years

What can we learn from the experiment？A.daily amount of food may influence our health

B.sleeping may have nothing to do with weight

This passage is mainly about the relationship between___________A.food and health

Passage Two

Questions 26 to 30 are based on the following passage.

Tides are created mainly by the pull of the moon on the earth. The moon's pull causes water in the oceans to be a little deeper at a point closest to the moon and also at a point farthest from the moon, on the opposite side of the earth. These two tidal “waves” follow the apparent movement of the moon around the earth and strike nearly every coast line at intervals of about twelve hours and twenty-five minutes. After reaching a high point, the water level goes down gradually for a little more than six hours and then begins to rise toward a new high point. Hence, most coast lines have two tides a day, and the tides occur fifty minutes later each day. Differences in the coast line and in channels in the ocean bottom may change the time that the tidal wave reaches different points along the same coast line. The difference in water level between high and low tide varies from day to day according to the relative positions of the sun and the moon. The sun also exerts a pull on the earth, although it is only about haft as strong as the pull of the tides arise higher and when they pull at right angles to one another. the tide is lower. The formation of the coast line and variations in the weather are additional factors which can affect the height of tides. Some sections of the coast are shaped in such a way as to cause much higher tides than are experienced in other areas. A strong wind blowing toward the shore may also cause tides to the higher.

Which of the following is right according to the passage？

A. Some coast lines do not have two tides each day.

B. Tides are not affected by the shape of coast line.

C. The sun has as much effect on tides as does the moon.

D. Tides usually rise to the same land day after day.

Passage Five

Jim was intelligent, but he hated hard work. He said, "You work hard, and make a lot of money, and then the government takes most of it. I want easy work that gives me lots of money and that the government doesn't know about".

It was evening, and when the man looked through one of the windows, he saw a young man and a girl playing on a piano.

Passage One

One of the well-known of American writers is Samuel Clemens, whose pen name is Mark Twain. Bom in 1835, Twain grew up in the Mississippi River town of Hannibal, Missouri. As did many other boys of his day,

Twain dreamed of traveling on river boats and of someday becoming a riverboat pilot. Twain used his memories of the life of a river town in his two most famous books, Huckleberry Finn and Torn Sawyer.

As a young man, Twain held many jobs. He was a printer, a good miner, and, for a time, he was a riverboat pilot. During his pilot days, he adopted the name Mark Twain. This was a term used by the boatmen to mean that the water measured two fathoms, or twelve feet, which was deep enough for safe passage.

Finally Twain became a successful writer. He traveled a great deal, writing and speaking, and became very popular both in the United States and in Europe.

Twain's style. of writing was simple and direct. Among the things he wrote about were superstitious (迷信的) people and people who were easily fooled. He used his unusual gift for humor to write about many things of importance.

36. Generally speaking, this article is about______.

A. a riverboat pilot

B. a printer

C. a gold miner

D. a famous writer

s. One reason is that out at sea, waves moving in one direction almost always run into waves moving in a different direction. The two sets of waves tend to cancel each other out. Another reason is that water is shallower near the shore. As a wave gets closer to land, the shallow bottom helps reduce its strength.

But the power of waves striking the shore can still be very great. During a winter gale, waves sometimes strike the shore with the force of 6,000 pounds for each square foot. That means a wave, 25 feet high and 500 feet along its face, may strike the shore with a force of 75 million pounds.

Yet the waves, no matter how big or how violent, affect only the surface of the sea. During the most raging storms, the water a hundred fathoms(600 feet) beneath the surface is just as calm as on a day without a breath of wind.

According to the passage, destruction caused by high waves occurs ______.

A．regularly

B．rarely

C．always

D．predictably

However, men quickly found more convenient and reliable ways of telling the time．

They learned to use the shadows cast by the sun．They marked the hours on candles, used sand in hour-glasses, and invented water-clocks．Indeed, any serious student of antiques should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past．

Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home． After all, if you are going to be ruled by the time, why not invest in air antique clock and perhaps make a future profit？
