Library books should____ ____ ____ on time.
分析:答案为be given back。被动句中含有情态动词should,因此助动词用be。
2. It is widely accepted that more people use computers in the world today.
Computers ____ widely ___ in the world today.
分析:答案为are,used。computers是复数名词,助动词用are。
四、非延续性动词与延续性动词的相互转换
即非延续性动词与延续性动词进行转换,此时往往会涉及时态的变化。如:
1. The manager left two hours ago.
The manager _____ ____ ____ for two hours.
分析:答案为has been away。leave为非延续性动词,不能与for two hours这样的一段时间连用,而改成be away这样的延续性动词后,则可连用一段时间。
2. The film began five minutes ago.
The film has been _____ _____ five minutes.
分析:答案为on for。has been提示时态是现在完成时态,for+时间段表示持续(一段时间),常用在含有现在完成时态的句子里。
3. Mr Li joined the Party twenty years ago.
Mr Li _____ _____ _____ the Party for twenty years.
答案:has been in。短暂动词join,意为参加、加入(组织,政党),不能与延续时间状语连用,与延续性时间状语连用时,将join改成be in或be a member in。
