He is working for a big firm...,  只有  d. Timis 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 abroadbefore ,  ,应该选  b.其他  3 个选 择都与课文内容不符合。 3. ab. 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 连用 go to 才能表示到某个地方去，如国家，城市等，所以选 a.  go 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. ba. 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 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。 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。 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
