四.語法知識
1.現(xiàn)在完成時的概念， 結(jié)構(gòu)以及在各種句式中的運用
基本結(jié)構(gòu)為have/has+過去分詞
（1）表示過去發(fā)生的行為，動作，情況對現(xiàn)在的影響或造成的結(jié)果。時間副詞常用just, already, still, recently,yet,ever,never. 其中just, already用于肯定句，yet,ever,never常用于疑問句和否定句。而still, recently可用于肯定句，否定句和疑問句三類句式。 如：
have you ever been to hongkong?
i haven’t got the letter from my uncle yet.
(2)表示過去開始持續(xù)到現(xiàn)在的行為，動作，情況。常與for, since引導的時間狀語連用。for表示一段時間，后接時間長度。since表示自從， 后接時間起點。也常與so far, in the past several years這類從過去到現(xiàn)在的時間狀語連用。 此類動詞中，謂語動詞要用持續(xù)性動詞，而不能為短暫性動詞。
the children have been away from home since the new term began(不用left)
(3) 在含有持續(xù)長度時間狀語的現(xiàn)在完成時句子中，不能用短暫性動詞，而應使用持續(xù)性動詞，或相當于可持續(xù)性動詞的動詞短語。 如：
