用括号内所给词的适当形式填空（每空不限一词）。
【小题1】If you aren’t/are not (not be) careful enough in the exam, you will not get a good grade.
【小题2】Our modern times need more and more heroes (hero) for us to learn from.
【小题3】Good habits are good for the development(s) (develop) of us teenagers.
【小题4】The 30th Olympic Games will be held/ is/are going to be held (hold) in London this summer.
【小题5】— Look! He is shouting at his mother.

【小题9】Though my grandfather is in his seventies (seventy), he has got a QQ number.
【小题10】Lei Feng devoted himself toworking 。 (work) for the people all his life.

解析：【小题1】根据if的用法，当主句是一般将来时，从句用一般现在时。根据you，后面应用are的否定式，即aren’t或are not。【小题2】heroes 根据句意：“现在我们所生活的的时代，需要越来越多的英雄供我们学习”，本题应用hero的复数形式，即heroes。【小题3】根据句意：“好习惯对我们青少年的成长有好处”，故本题用develop的名词形式development(s)。【小题4】根据句意：“今年夏天，第30届奥运会将在伦敦举行。”，本题应用一般将来时的被动语态。【小题5】根据句意：“—看！他正在对他母亲大叫！—他为什么这么不礼貌？”，本题应用polite的反义词impolite。【小题6】根据句意：“为了想出答案，这群学生正积极地讨论这个问题。”，本题考查副词修饰动词，故答案为actively。【小题7】根据句意：“3D影片《泰坦尼克号》是我看过的最精彩的影片.”，本题考查形容词的最高级，因前面已有the，故答案为most wonderful。【小题8】本题考查“特殊疑问词+动词不定式”，构成动词不定式短语。【小题9】seventies 根据句意：“虽然我的爷爷七十多岁了，但他还有一个QQ号”，本题考查短语“在某人70多岁时”用in one’s seventies。【小题10】根据句意：“雷锋同志把他的一生都奉献在为人民服务的工作上”，本题考查短语devote oneself to…，其中to是介词，后需要接动名词。

回答的不错
