題目列表(包括答案和解析)

Some mammals migrate(遷徒). One of these is the caribou(馴鹿). They travel to the tundra(苔原)every summer to eat the rich grasses that grow there. When the weather becomes cooler, they migrate to the warmer forests and spend the winter there. Another mammal that migrates is the humpback whale. They spend the winter in Hawaii, and the summer in the Arctic(北極的)waters. They travel to the Arctic to eat millions of small shrimp(蝦).

Anther habit that some animals have to survive the cold winter is called hibernation. Animals that hibernate, rest or sleep during the winter. While they are hibernating, their bodies use up the fat layer that they have put on by eating large amounts of food during the summer. Some animals that hibernate in the Arctic are small animals called lemmings(旅鼠), squirrels(松鼠)and bears.

There are two habit adaptations that animals in the Arctic have all year round. These are called herding and pack life. Caribou are example of animals that live in herds. A herd is a group of animals that lives together for most, or all of their lives. A herd of caribou can have a thousand or more animals in it. They live in herds for protection. It is easier for caribou to protect themselves when they are together than it is when they are alone. This is because the meat-eaters hunt in packs.

A pack is a small group of animals that lives together. It is usually controlled by a head male and a female. All the members of the pack must obey them. Packs have a very definite social structure. Each animal in a pack has a different position, or importance. Animals in a pack are usually meat-eaters. They live together for protection and hunting purposes.

According to the first paragraph, the humpback whale         .

A. travels to the Arctic for shrimp in summer

B. spends the winter in the Arctic

C. lives in Hawaii in summer

D. has the same living habits as the caribou

What kind of animal doesn’t hibernate in the Arctic?

A. The caribou.                    B. The bear.           C. The squirrel.             D. The lemming.

Caribou live in herds in order to         .

A. use up their fat layer        B. find food        C. protect themselves     D. hunt in packs

What do we know about pack life according to the last paragraph?

A. Animals in pack are usually grain-eaters.

B. All animals are in an equal position in a pack.

C. It is either controlled by a head mate or by a female.

D. Each animal has its own different role in a pack.

A father sat at his desk poring over his monthly bills when his young son rushed in and announced, "Dad, because this is your birthday and you're 40 years old, I'm going to give you 40 kisses, one for each year!" When the boy started making good on his word, the father cried out suddenly, "Oh, Andrew, don't do it now; I'm too busy!"

The youngster immediately fell silent as tears welled up in his big blue eyes.Apologicaliy the father said, "You can finish later."

The boy said nothing but quietly walked away, disappointment written over his face.That evening the father said, "Come and finish the kisses now, Andrew!" But the boy didn't respond.

Unfortunately, a few days later after this incident, the boy had an accident and was drowned.His heartbroken father wrote...

"If only I could tell him how much I regret my thoughtless words, and could be sure that he knows how much my heart is aching."

Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.

The ridge structure on a person’s fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.

Finger-prints can be made very easily with printer’s ink. They can by recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.

When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to “develop” them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

Notes:

unique  adj. 唯一的,獨(dú)特的

original  adj. 最初的,原始的

identification  n. 辯認(rèn),鑒定

A. using printer’s ink           B. injuring the inner skin

Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station(加油站)about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register(收款臺(tái)), I said hello to an older couple who were also paying for gas.

I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.

I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I'd left the lights on all day, and the battery(電池)was dead. Then I noticed that the Friendly Ford dealership - a shop selling cars - was right next door. I walked over and found two salesmen in the showroom.

"Just how friendly is Friendly Ford?" I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.

"Thank you" - two powerful words. They're easy to say and mean so much.

B. The couple sent him a business card.

D. He called his friend for help.

A. something went wrong with the lights

B. the meeting lasted a whole day
