Go originated in China more than 2,500 years ago. __【6】__ game involves two players who take turns putting markers on a checkerboard-like grid.

【2】alled

【3】its

【4】conducting

【5】games

【6】The

【7】by

【8】but

【9】has worked

【10】that

【解析】

【1】該空格前是一個定冠詞the，故空格中應該用名詞，故填development。

【2】分析句子，可知該空格處要用一個非謂語動詞；由于call與主語program之間是被動關系，故用過去分詞形式，故填called。

【3】分析句子，可知本句的意思是：開發(fā)者們說它們的學習能力可能某天會讓電腦幫助解決真實世界中的問題。故填its。

【4】and連接的是兩個并列動詞，根據(jù)該空格前的making可知，此處用現(xiàn)在分詞形式，故填conducting。

【5】分析句子，可知空格前是代詞other，故其后要用名詞復數(shù)，故填games。

【6】根據(jù)句意，可知空格后的game指代的是上文提過的，故在其前面要用定冠詞the。

【7】根據(jù)句意，可知此處表示的是一種方式，而且空格后是動名詞，故可知此處應該用介詞by。

【8】分析句子，可知本句中缺少連詞。根據(jù)句意，可知前后兩個句子之間是轉折的邏輯關系，故用but。

【9】分析句子，可知本句中有標志性時間狀語for 30 years，故本句要用現(xiàn)在完成時，故填has worked。

【10】分析句子，可知這是一個定語從句，從句中缺少了賓語，而先行詞是everything else，故用關系代詞that。

【題目】Science has a lot of uses. It can reveal (揭示) laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there’s always a temptation (誘惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal, The Hidden Sources of Love, Character, and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.

Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren’t?

To answer these questions, Brooks surveys a wide range of subjects. Because of this, you might expect the book to cover a variety of facts. But Brooks has structured his book in an unusual, and perhaps unfortunate way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader’s attention. So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.

On the whole, Brooks’s story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks’s attempt to translate his tale into science.

【1】The author mentions the functions of science at the beginning of the passage to ________.

A. show the value of Brooks’s new book

B. show where science can be applied

C. remind the reader of the importance of science

D. explain why many writers use science in their works

【2】According to the author, which of the following could be a strength of the book?

A. Its clear writing.

B. Its convincing points.

C. Its strong characters.

D. Its strong basis.

【3】What is the author’s general attitude towards the book?

A. Cautious.

B. Critical.

C. Contradictory(矛盾的).

D. Supportive.

Hello Russell,

How are you? I didn’t see you in class last week, and your sister told me that you had a cold. Are you feeling better now? Mr. Carlson teaches us some new things in math class, and they’re really hardly. I took lots of notes, but I’ll let you borrow them.

Anyway, I wanted to talk to you about a event called Safe Town. The Graysville Fire Department is going to have special classes to young kids for one week in March. In it, people from town will teach the kids about road and bicycle safety. Someone came to our high school on Wednesday and talked about them. They’re looking for people to teach the classes, and I’m really interesting in it. I thought you might be, too.

We won’t get pay for it, but our homeroom teacher says that it will be good experience. Also, does these kinds of activities can help you get into a good college. Let me know what you think!

See you,

Marcella

Dear Mr. Smith,

I’m very much glad to hear that your international shopping center will build non-smoking supermarket. In my opinion, it is a good idea to do so, for it can not only help the smokers to smoke less, and it can also do good to other customers’ health. Since you had given up selling cigarettes, the customers who doesn’t like smoking are sure to support you. In addition, smoke in the shopping center may cause fire, which is very dangerous to both your possession and the safety of the customers. In a word, the non-smoking supermarket will not effect your business. To the contrary, it will help you attract more customers who want to keep health.

Best wishes!

My four-year-old son ran down the stairs very excitedly in Christmas morning and went straight for the gifts under the tree. And, to my surprise, the first gift he grabbed was a gift he had been made for his father and me. He stood there with joys and patience as we opened our gift. When I saw the gift, that was a hand-made wreath made his small handprints, I started to cry. My husband leaned over and asked how I was crying. I said I can not believe the thoughtfulness of this child. My son was most exciting about giving us the present he had made for us. I felt proud for him. That is actually the best gift I received for Christmas.
