---You look unhappy, what’s happening, my son? ---I’m wondering how long it’ll be________ we come to China again. A.since | B.when | C.before | D.after |

答案
C |
解析
试题分析:考查句型:It will be +一段时间+before…,要多长时间才…,这句话是这个句型的特殊问句,how long对一段时间提问,句意:---你看起来很不高兴,怎么了?--我想知道什么时候才可以再来中国。选C。 点评:固定句型:It was+一段时间+before…,要多久…就(才)…,在考试中出现的很多,容易混淆的句型是it is/has been 一段时间since从句(过去时);自从…以来,已经有一段时间了。区分的时候,一是从句意判断,还有就是根据主句的时态区分。 |
