It is + adj. + for sb. to do（形容词描述事物特征）→ It is important for us to study hard. 感叹句：What + a/an + adj. + n.! → What a great scientist he is! 感叹句：How + adj./adv.! → How hard-working she is! 语法八：现在完成时的延续性动词转换 瞬间动词不能与for/since连用，需转为延续性状态 buy→have, borrow→keep, die→be dead, leave→be away from join→be in / be a member of, begin→be on, get married→be married He has been in the army for 3 years.（× has joined for 3 years） 第四部分：十大重点易错考点专项训练 全卷共10大考点 × 9题 = 90题 ｜ 基础题（◇）3 + 提升题（▷）3 + 拓展题（★）3 考点一：used to do / be used to doing / be used to do 三辨析 ◇ 基础题（选择题） （ ）1 Chen Wei ______ live in a small village, but now he ______ in Qingdao.
