几个英语小问题
1.To learn a foreign language well is useful,I think.(改为同义句）
I think it useful to learn a foreign language well .
这里的第二句话中为什么用it而不是it's
2.If you are lazy,you may not pass the exam.(改为同义句）
Work hard,or you may fail the exam.
里的第二句话的第一个词,为什么用work,而不是working.当一句话的第一个词是动词时,什么时候用原型,什么时候用ing形式,什么时候用动词不定式.
3.You ——to the meeting this afternoon if you have something important to do.
A.neeedn't to come B.don't need to come
C.needn't coming D.didn't need coming
这道题为什么选B,而不是A

1.I think it useful to learn a foreign language well .此句为宾语从句原型是：I think that it useful to learn a foreign language well.这句的主语是我,it是think的形式宾语,正真的宾语是useful to learn a foreign language well.我这样说不知明白没.举个例子：I believe that this house is for sale.主语I,谓语believe,that引导宾语从句,这里我想你看到is了,这里的is for sale是固定搭配,意思是待售,sale是个名词.
2.Work hard,or you may fail the eaxm.此句为祈使句."hard"这里的词性是副词,修饰前面的“work",此时的“work"词性是动词.“work hard”强调努力学习这个动作,而working hard,此时working是名词译为工作、劳动,hard是形容词译为刻苦的、努力的,形容词修饰名词强调状态.不管怎么变,首先你要搞清楚每个词的词性,它是用来修饰什么词的,这是一个句子的重点.
3.首先了解全句的意思：如果你有重要的事要办今天下午都会议你就没有必要来了.看这4个答案,我们进行筛选法来做此题,第一步：了解need的词性,它可做名词,及物和非及物动词,以及情态动词,在这里我们可以判断need是动词类,那么名词词性去掉.而情态动词后必须跟动词原型,看看这4个中都没有一个符合,那么我们就来考虑动词词性,need做非及物动词讲译为生活穷困,显然不合题意,那么我们确定need就为实义动词,即及物动词.它做及物动词有个固定搭配（not）...need to do sth.（没）有...必要做某事.举个例子：I don't think you need to worry about this.我认为你不必为这事担心.它还有个搭配是need +V.ing...也是译为有...必要,这里动词加了ing是把动词变为动名词,这里充分体现了动词与动词不能连用的原则.当need做实意动词讲其后不能直接not,而必须加助动词do,did之类,needn't的形式只有做情态动词时才有这种形式.所以这题只能选B.
不知道我这样的解释你是否明白,希望这些能够帮到你.我想,在做题目的时候首先审题是最重要的,英文题目最重要的还是词性,建议在背单词的时候记住单词的词性,因为这样你才知道什么样的词做宾语,谓语等.
