In 1973, he grew the world’s first hybrid rice strain (品种). It could reach a yield of over 500 kg per mu (亩产). Farmers can grow it on many different kinds of land.

一、单项选择
1．After school, I play soccer ________ my classmates ________ two hours.
A．and; for B．and; in C．with; for D．with; on
【答案】C
【详解】
句意：放学后，我和我的同学踢两个小时的足球。
考查介词辨析。and和；with与……一起；for后接一段时间；in后接一段时间，句子用一般将来时；on后接具体一天；in后接某年某月某季节。play with“与……一起玩”，故第一空填with，排除A和B选项。two hours是一段时间，故第二空填for，故选C。
2．—Mom, can I watch TV now
—No. You can’t watch it ________ you finish your homework.
A．because B．as long as C．after D．until
【答案】D
【详解】
句意：——妈妈，我现在能看电视吗？——不能。你直到完成作业才能看电视。
考查从属连词。because因为，引导原因状语从句；as long as只要，引导条件状语从句；after在……之后，引导时间状语从句；until直到……时候，引导时间状语从句。分析句子可知，not ... until ...表示“直到……才……”，此处表示“直到做完作业才能看电视”。故选D。
3．Shanghai is such a big city. There are over ________ people living in the city.
A．millions B．26 million C．26 million of D．millions of
【答案】B
【详解】
句意：上海是一个很大的城市。有超过2600万人居住在这个城市。
考查数词用法。million的常见搭配有：“基数词+million”表示具体的数量；millions of“数以百万计的”。结合空前over可知此处用26 million表示具体的数。故选B。
4．Uruguay didn’t win the World Cup in 1930, did it
A．Yes, it did. B．Yes, it didn’t. C．No, it didn't. D．No, it did.
【答案】A
【详解】
句意：乌拉圭没有赢得1930年的世界杯，是吗？
考查反意疑问句。反意疑问句作答时，事实是肯定的，用“Yes,人称代词+助动词”回答；事实是否定的，用“No ,人称代词+助动词+not（用缩略式）”；所以排除B和D；根据事实，乌拉圭赢得1930年世界杯冠军，排除C。故选A。
5．Which of the following is CORRECT
A．How good advice he gave you!
B．What fun Christmas performances they were!
C．How fun Christmas performance it was!
D．What a good advice he gave you!
【答案】B
【详解】
句意：下列哪项是正确的？
考查感叹句。A项错误，根据“good（形容词）advice（不可数名词）he（主语）gave（谓语）you（宾语）”，可知，应用what引导感叹句；B项正确，是“What+形容词+名词复数+主语+谓语！”结构；C项错误，how引导的感叹句的结构为：How+形容词/副词+主语+谓语！，故应去掉it；D项错误，advice“建议”，是不可数名词，不应加a。故选B。
6．—Tommy wants to invite us to dinner.
—Great! I ________ what to eat for dinner!
A．have just thought B．just thought
C．just think D．was just thinking
【答案】D
【详解】
句意：——汤米想邀请我们共进晚餐。——太好了！我刚才在想晚餐吃什么呢！
考查动词时态。think想，动词；just刚才，副词，修饰动词think；结合语境可知，说话人说汤米想邀请我们共进晚餐之前，我正在想晚餐吃什么。因此，此处强调的是过去某一时间段，一直在发生的动作，应使用过去进行时，其构成为was/were+动词的现在分词，主语是I，be动词用was；think的现在分词是thinking。故选D。
7．He supposed we could finish the project on time, ________
A．did he B．didn’t he C．could we D．couldn’t we
【答案】B
【详解】
句意：他以为我们能按时完成这个项目，对吗？
考查反意疑问句。分析句子结构可知，此处为反意疑问句。若主句是肯定句，则反意疑问句要用否定的语气；若主句是否定句，则反意疑问句要用肯定的语气。该句子的陈述句部分是肯定句，且谓语动词是实义动词，此处需借助助动词构成反义疑问句，陈述句是一般过去时，此处助动词用didn’t，故选B。
8．Which sport do you like ________
Which answer is NOT correct
A．joining a B．playing C．joining D．taking part in
【答案】C
【详解】
句意：你喜欢参加哪项运动？哪个答案不正确？
考查非谓语动词。like doing sth.“喜欢做某事”；Which sport“哪项运动”，在句中作动词的宾语，sport是名词单词，可以说joining a sport“参加一项运动”，play sport“作运动”；take part in sport“参加体育运动”，选项C是错误的，故选C。
9．My birthday is ________ May and his birthday is ________ March 26th.
A．in；in B．in；/ C．for；on D．in；on
【答案】D
【详解】
句意：我的生日在5月，他的生日在3月26日。
考查时间介词辨析。in用于年、月、世纪、四季之前；for后接一段时间；on用于具体的某一天或具体某一天的上午，下午或晚上前。第一个空，“May”表示“5月”，指的是月份，因此介词用in；第二个空，“March 26th”表示“3月26日”，指具体的某一天，用介词on；故选D。
10．After ________ students, Macy won the speech contest and the trophy________ her at the closing ceremony.
A．winning;selected B．competing;was placed to
C．beat;was given to D．defeating;was presented to
【答案】D
【详解】
句意：击败学生后，Macy赢得了演讲比赛，在闭幕式上向她颁发了奖杯。
考查非谓语动词及动词辨析。after是介词，其后要跟动名词作宾语，排除C选项。win“赢得，获胜”，后接表示某种比赛的名词或战争作宾语；defeat“战胜，赢得”，后接表示表示人或代表群体的名词或代词；compete“竞赛”。根据第一空后的“students”可知，应使用defeating；sth. be presented to sb.“某物被颁给某人”。故选D。
