2，關于現在完成時求一道例題答案解析

解釋如下：he claims to （have） seen a snowman in the mountain.他聲稱在山上看見了一個雪人。括號里的has要改為have。可以理解為to 這里是動詞不定式，后面接動詞原形。故采用have.

正是因為沒有具體的時間，表示已經發生的動作對現在的影響，用現在完成時。Jack has forgotten to call his mother.忘記給他媽媽打電話。再如：I have seen the film.電影我看過，知道它的內容和好看不好看。如果用過去時，加個具體的過去時間：Jack forgot to call his mother yesterday.I saw the film yesterday,只是強調是昨天看的。其它情況無所謂。

3，初二英語現在完成時練習題

1.polluted (the poison in the waste是句子主語，這個句子是缺謂語，應該填動詞.其實沒有上下文的話用pollutes是可以的，但如果有上下文的話就要看時態了) 2.were(there be句型是采用就進原則，后面的people在這里是“人”的總稱，應是person的復數形式，所以用were) 3.did,move to（從這個中文翻譯來看應該是用過去時，move to 是固定搭配） 4.In the past, few people knew me.(“過去”一般可用in the past來表示，當然，把before放在句末也可做同意，“很少”在這里不用譯為not many，這樣會顯得很Chinglish，直接用few就行了) 5.I lived together with my parents till 1990.(如果用until的話需換成過去完成時：I had lived with my parents until 1990.) 6.This place has been changed into an airport.(注意要用完成時時不要用短暫性動詞，例如die，一個人總不能一直在死吧？） 7.joined,since（注意joint是一個adj,表示結合聯合，而不是join的過去式） 8.How long（這個是叫你對時間的長短進行提問，所以用how long）
