  3多项选择答案

  1. d

  根据课文内容Tim is an engineer. He is working for a big firm..., 只有d. Tim is working for a big firm as an engineer 是对的,其他3个与文章不符合。

  2. b

  根据课文的最后一句My brother has never been abroad before…,应该选b.其他3个选择都与课文内容不符合。

  3. a

  b. in(在……里面)不能和动词go连用;c. at(在……地方)也不能同go 连用;d. into(进入……内)可以与go连用,但是到某个国家不能用go into; 只有a. to 同动词go 连用 go to 才能表示到某个地方去,如国家,城市等,所以选a.

  4. b

  本句是问“他在那儿呆了多久”。因为说话时他还在那,所以应该用现在完成时态。

  a. is he 是一般现在时;c. has he 中没有过去分词been, 不符合语法;d. was he 是一般过去时;只有b. has he been 是现在完成时, 所以选b.

  5. b

  a. for 只有同表示一段时间的词连用时候才能用在完成时中,如for six months, for one year等.

  c. from 常与介词to连用表示"从……到……",它很少用于现在完成时;

  d. by 可以表示时间“到……为止”,常用于过去完成时中和将来完成时中,但是它用在本句意思不对;只有b. since(从……以来)可以用在完成时态中,选b.才能使句子的时态和意思正确并且合乎逻辑。

  6. a

  本句的意思是“他刚刚买了一辆澳大利亚小汽车”强调买的时间短,用just来表示。

  b. a long time ago(很久以前)与原来句子不符合。

  c. last year(去年)也跟原来句子不符合。

  d. six months ago(6个月前)也不对,句子中没有明确说明;

  只有a. a short time ago(不久前,最近)同just的意思相近,所以应该选a.

  7. c

  本句需要用现在完成时,已经给出了助动词has,只需要填上过去分词就可以了。a. went 是过去式; b. being 是现在分词;d. was 是过去式,只有c. been 是过去分词,所以选c.

  8. b

  本句需要选出与firm(公司)的同意义词。 只有b. company(公司)和firm 的词意思相同。 而其他3个a. society(社会),c. factory(工厂),d. store(商店)都不是firm的同意义词,所以选b.

  9. c

  本句需要选出一个与前一句的different相对应的词.a. the only (唯一的)不是different的反义词. b. a similar (相似的,类似的)也有同样的意思,但是它不是和different相对应的反义词;d. alike(相象的,相同的)通常做表语. 只有c. the same(同一的,同样的)是different的反义词,所以应该选c.

  10. a

  只有a. bigger than a village but smaller than a city 才能准确表达town的含义,而其他3个选择都不表示这个意思。

  11. c

  本句需要选出一个同前一句soon(不久)意义相接近的词,a. quickly(快速地),b. for a short time(短时间),d. in a hurry(匆忙地)这3个选择都与soon意思不同,只有c. shortly(不久)是soon 的同义词.

  12. c

  本句需要选出同前句中fly(飞,乘飞机)的意思相应的短语。

  只有c. by air 是固定短语,表示方式, go by air 是惯用法,意思是“乘飞机去”,而a. with air, b. in air, c. through air 都不是固定短语,意思都讲不通,所以选c.
