资源简介
语 境 自 主 领 悟
先观察原句
后自主感悟
①I haven't seen Justin since.
②Detective Sam Peterson,who has taken charge of the case,told journalists,‘Sometimes people make up such amazing stories...’
③From our recent survey of students,we have found that 53 per cent of the students often play sports.
④For centuries,people have reported seeing a wild creature in the Himalayas called Yeti.
⑤Large tracks have also been discovered which some people say belong to the Wild Man.
⑥This incident has received great interest due to reports of strange lights in the sky and of alien visits around the time the boy disappeared.
⑦I've been writing the composition for two hours,but I haven't finished it yet.
⑧I have been wanting to meet you for a long time.
1.句①~⑥中均运用了现在完成时,其谓语动词的构成形式为:have/has+过去分词
2.句⑦⑧运用了现在完成进行时,其谓语动词的构成形式为:have/has+been+现在分词,表示过去发生的动作一直持续到现在。
3.现在完成时有两个基本用法:一是表示过去发生的动作对现在造成的影响或结果,如句②③⑤⑥;二是表示过去开始的动作一直持续到现在,并且有可能继续下去,如句①④。
