Another eager beaver works as a salesman for a business. He   6   arrives at the office before anyone else, and is the    7   person to leave.

The man works hard, because he   8   his job. He is a true “eager beaver”.

The expression   9   the name of a hardworking animal, the beaver. Beavers are  10  creatures. They are like mice and rats, but much   11   . Some weigh more than twenty-five kilograms. Beavers have a large, black, flat tail to   12   them swim. They also have thick brown hair or fur to keep them warm in cold  13  .They have front teeth  14  enough to cut down large trees.

Beavers spend a lot of time in the water, building dams to form little   15   or pools. They work hard to cut down trees,   16   branches and put them across streams. They use their tails to pack mud on the branches to make the dams solid.  17   other animals work so hard.

In fact, for two hundred years or more, the beaver was the most valuable animal in North America. And thus most of the beavers were killed. For a time, they were in danger of  18  completely. But laws were passed to   19   the beaver, and today, the    20   is rising.

答案:B;A;D;A;C;C;B;D;A;C;B;D;C;D;A;C;D;B;D;B
解析:

1、instead of doing sth.,而不要做……。

2、此處填的詞應同于前句的“…h(huán)er students”,故用children取代。

3、此處所填的詞對應于complain一詞,后接賓語內容,所以選say。

4、這種學生就像勤勞的海貍,喜歡算數(shù)學題。

5、老師讓學生在家做的作業(yè)應為homework。

6、always表肯定,加強語氣符合句意。

7、既然是個eager beaver,理應最早上班,最遲下班。

8、因為是“…a true eager beaver”,所以他應該喜歡他的工作。

9、eager beaver這個詞語來源于一個動物的名字。

10、根據(jù)下文可知它有尾巴,排除A項,D項課文沒有涉及,另據(jù)后面內容,可知這一動物長相奇特。

11、根據(jù)后面,它有25公斤多重,所以理應比老鼠大得多。

12、海貍的尾巴很顯然是幫助它在水里游泳的。

13、據(jù)后面提示可知,海貍大多數(shù)時間都在水里度過,它身上的皮毛可以幫助它抵御寒冷,保持溫暖。

14、牙齒可以咬倒大樹,可見它的鋒利。

15、壩子圍起來的該是小池子或小湖,A項符合題意。

16、根據(jù)這一連串行為,先把樹咬倒。最后從溪流中把樹枝帶到對岸,所以中間所填的一詞應是remove(搬運、搬走)。

17、很少有其他的動物像海貍這樣勤勞。

18、因大部分海貍被殺,所以說,有一段時間,海貍處在滅絕的危險之中。

19、法律是為了保護海貍而被通過,這樣才能和前句構成轉折。

20、此處應指海貍的數(shù)量。

Entrants(參加者)were to tell an interesting story about their    39   . Winners would receive a phone call from Mrs. Santa Claus(女圣誕老人)! Mrs. Claus would award(獎勵) the lucky child free    40    of a local store.

     Well, the call came. My mother talked to Mrs. Claus and then    41    the phone to me. I didn’t    42    the fact that many people were listening to our conversation. However, the fact that this lady had a    43    connection to Santa, that was important.

I recently heard a story about a famous scientist who had made several very important medical breakthroughs. He was being interviewed by a reporter who asked him    36   he thought he was able to be so much more    37   than the average person.

He    38   that it all came from a(n)   39   with his mother that occurred when he was about 2. He had been trying to remove milk from the fridge when he    40   the slippery(光滑的) bottle, its contents running all over the kitchen floor.

When his mother came in,    41   shouting at him or giving him a lecture, she said, "Robert, what a great and wonderful    42   you have made! I have    43   seen such a huge pool of milk. Well, the damage has already been    44  . Would you like to get down and    45   in the milk for a few minutes before we clean it up?"

Indeed, he did. After a few minutes, his mother said, "Robert, whenever you make a mess like this, eventually you have to    46   everything to its proper order. So, how would you like to do that? We could use a sponge(海綿), a towel or a mop. Which do you prefer?" He chose the sponge.

His mother then said, "You know, what we have here is a    47   experiment in how to effectively carry a big milk bottle with two    48   hands. Let's go out in the back yard and fill the bottle with water and see if you can make it." The little boy learned that if he    49   the bottle at the top near the lip with both hands, he could carry it without dropping it. What a wonderful    50  !

This scientist then remarked that it was at that moment that he knew he didn't need to be    51  to make mistakes. Instead, he learned that mistakes were just    52   for learning something new, which is,    53  , what scientific experiments are all about. Even if the experiment "doesn't   54  ," we usually learn something    55   from it.

When I began my high school years, I was quite interested in biology. I read lots of books of my father’s about animals, and I was   36   much educated about such matters as a 16-year-old could be.

    One Sunday afternoon, I was   37  with friends about animals. I said the whale(鯨魚)was   __38  a mammal animal. They disagreed. Finally, I called a   39   over to help settle the matter. I knew I was  40  , so I was looking forward to the teacher  41   I was right. My friends were eager for an opposite answer. We asked her   42  the whale was a mammal. “No, the whale is a fish,” she said without a moment’s   43  .

You could have knocked me over with a feather. My   44   was hurt because I lost the argument, but that wasn’t the main reason I was too  45  to speak. I still knew I was right, which   __46  the teacher was wrong. Not only was she wrong,   47   she was completely ignorant(無知的) about something I thought was   48   knowledge. But she was a teacher who had taught a long time. Everyone   49   her and no one else thought she could be wrong.

__50  that, I hadn’t known grown-ups could be wrong. This   51  shaped the way I viewed people as I grew up.   52   I found anyone treated another person with too much respect and admiration, I thought——and still think——“   53   silly.” From that point on, I had no  54__ for authority(權威).
