现在时，所以从句也应该与现在有关。如：He hasn’t been having much luck since he came here。他自从到这儿没交多少好运。
44. Because of the reduction of air pollution, this city now is a good place _______.
A. where to live B. which to live C. to live D. to be lived
解答：选（A）。本题考查是一种特殊形式的不定式短语，wh－词 + 带to的不定式作后置定语。因live是不及物动词，只能为live in + 地点，所以可以是in which to live，而in which在这里表地点相当于where。如：He told me where to take the ID photo.他告诉我到哪里去照身份证照片。
45. Thousands of products _______ from crude oil are now in daily use.
A. to make B. be made C. making D. made
解答：选（D）。过去分词做定语，分词与被修饰词之间是动宾关系，表完成和被动，此句相当于定语从句thousands of products which are made from crude oil are now in daily use.又如：The cookie made by my mother is better than I did妈妈作的糕点比我做的好。
46. ________ last Friday, he would have got to Paris.
A. Would he leave B. Had he left C. If he is to leave D. If he was leaving
解答：选（B）虚拟语气用于表示过去的条件句中，主句用would have + 过去分词，从句用had + 过去分词，省略if，助动词had要提到句首，从句要部分倒装。如Had you arrived earlier，you would have seen Professor Wang.如果你早点到，你就能看见王教授。
