【題目】—________ you ________your homework yet?

— Yes, I it an hour ago.

A.Did do, finishedB.Have done, have finishedC.Have done, finished

【答案】C

【解析】

句意：——你做完作業(yè)了嗎？——是的，我一小時前就做完了。

考查動詞時態(tài)及一般疑問句。根據(jù)yet及語境可知是現(xiàn)在完成時的一般疑問句，其結(jié)構(gòu)是have/has+主語+動詞過去分詞+其他？排除A；短語do your homework做你的作業(yè)；do的過去分詞是done。根據(jù)時間狀語“an hour ago.”可知此處用一般過去時態(tài)。finish動詞，完成，過去式是finished，根據(jù)題意，故選C。

【題目】閱讀短文，并按要求完成①～⑤題。

We all dream about things that we would like to do and things we hope to achieve in the future. But are everybody’s dreams the same? Here are some of the findings of a survey about hopes and dreams, in which thousands of students across China took part.

What are the hopes of teenagers(青少年)? We received several different answers to the question: what would you like to do after you finish your education? It seems some students would like to start work as soon as they can, so that they can help offer their parents better lives.

Other students hope to go on studying after they finish school and to go to university. Although money is important, many teenagers want to do jobs they like. According to the survey, the most popular choice of job is computer programming.

What are the dreams of teenagers? Teenagers have all kinds of dreams. Some are more realistic ( 現(xiàn) 實 的 ) than others. For example, many students would like to be volunteers if Beijing could hold the World Cup, maybe working as translators or tour guides. And many students dream of having a trip to every corner of the world one day.

According to the survey, less realistic dreams are also common, but many students reported that they were willing to work hard to achieve their dreams. Quite a few dreamed of becoming famous, perhaps famous sports people or singers. Some students would like to go on exciting trips. One student would love to sail across the Pacific Ocean. And then there are dreams that there are no possibility for students to achieve. Three students would like to be able to fly.

It is clear from the survey that teenagers have similar hopes. It seems that most students hope to have a good education and find a good job. On the other hand, students dream of very different things: good things, and even crazy things. It is very important to dream, so hold on your dreams, one day they may just be realized.

【1】完成句子Some students want to begin work as soon as possible to help________their parents better lives.

【2】完成句子 According to the survey , both realistic and________dreams are common.
