Unit 2 Working the land 第2单元 耕作土地(重点短语)--人教版新课标必修四第一单元学案

unit 2 working the land  第2单元 耕作土地(重点短语)

1. thanks to 由于;多亏(有时用作反语);因为

thanks to your help, we were successful. 由于你的帮助,我们成功了。

thanks to you, i was saved from drowning. 多亏你,我才没被淹死。

thanks to the bad weather, the match had been cancelled. 多亏了这倒霉的天气,比赛被取消了。(反语)

表示“因为,由于”的短语还有:because of,owing to,on account of,due to,as a result of。

以上这些都是介词短语,因此后面可以跟名词或动名词而不可以跟从句。

单项填空

①it was        your timely help that we accomplished the task on time.(2010·01·山西运城检测)
a. because b. thank c. thanks to d. as

        the new policy, we are now having a happy life.(2010·01·安徽亳州检测)
a. thanks to b. because c. for d. thanks for

①解析:选c。because 和as 虽然也表示“因为,由于”,但后面需接句子,而句中是短语,故应用thanks to。句意为: 幸亏你及时帮忙,我们才按时完成了任务。

②解析:选a。考查近义词辨析。thanks to意为“多亏了”;because后应加句子;for 表示补充说明的原因。

联想拓展

would rather...than...是常用句式,意为“宁可(愿)……(而)不要(愿)……”

would rather+从句时,从句要用虚拟语气,用动词的过去时表示。

would rather have done 本想做……(而实际上未做)

单项填空

①—shall we go skating or stay at home?
—which        do yourself? (2010·01·江西南昌检测)
a. do you rather  b. would you rather
c. will you rather d. should you rather

②i’d rather        the basketball match last night. otherwise, i would have finished my paperwork by now. (2010·01·江苏徐州检测)
a. not have watched b. not watch
c. hadn’t watch d. haven’t watch

①解析:选b。考查would rather do sth.这一结构的用法。而do, will和should都不能与rather 搭配。would rather (not) do sth.意为“宁愿(不愿意)做某事”。

②解析:选a。would rather not have done意为“本不想做……(实际却做了)”。后一句句意为:否则我现在已经完成了我的文件。 所以前句表示“本不想看球赛却看了”,故选a。

4. lead to 通向;导致;造成(后果)

注意:lead to中的to为介词,该短语后可跟名词或动名词。

eating too much sugar can lead to health problems. 吃太多糖会导致健康问题。

单项填空

the students in the university are all taking courses        a degree.(2010·01·山东烟台检测)
a. sticking to b. leading to c. turning to d. referring to

解析:选b。考查动词短语辨析。stick to 坚持; lead to 导致,引起;通往;turn to求助,转向,查阅;refer to 指的是;谈论,查阅。由句意“大学生都在学习课程,以取得学位”可知,答案为b。
