3. 语言点学习 Language Points
语言点一：It takes (sb.) some time to do sth.
【规则讲解】 It takes (sb.) some time to do sth. 做某事花费（某人）一段时间。
其中 it 为形式主语，真正的主语是后面的动词不定式（短语）。
拓展：人 + spend(s) + 时间 + doing sth / on sth
例句：It took them three hours to watch the movie.
例句：We spent seven days finishing the work.
练习1：选择题
I ______ two hours on my homework every day.
A. take B. spend C. cost D. pay
答案：______
练习2：汉译英
咨询师Linda花了两个小时跟Andy沟通。
译文：________________________________________
【易错提示】take/spend/cost/pay 的辨析
take：It takes sb. some time to do sth.（主语为it）；spend：sb. spends time/money doing sth / on sth（主语为人）；cost：sth. costs sb. money（主语为物）；pay：sb. pays money for sth（主语为人）。
语言点二：used to do sth / be used to do sth / be used to doing sth
【规则讲解】 used to do sth 过去(常常)做某事。
主语为人或物，表示过去经常发生的动作或存在的状态，现已不再如此。
拓展：be used to do sth 被用来做某事；be used to doing sth 习惯于做某事
例句：He used to be very shy and afraid to speak.
例句：This gym is used to hold school activities.
例句：My uncle is used to walking after dinner.

A. used to B. use to C. is used to D. was used to
答案：______
练习2：适当形式填空
He used to ______ (live) in a small village.
答案：__________
【知识拓展】used to do / be used to do / be used to doing 对比
used to do sth：过去常常做某事（to为不定式符号，后接动词原形）；be used to do sth：被用来做某事（to为不定式符号，被动语态）；be used to doing sth：习惯于做某事（to为介词，后接动名词）。
语言点三：be covered with sth
【规则讲解】 be covered with sth 被……覆盖。
为被动形式，其主动形式为 cover...with... “用……覆盖……”
例句：The ground is covered with snow in winter.
例句：She covers the teddy bear with a cloth.
练习1：选择题
Most of the mountain ______ trees.
A. cover with B. are covered with C. is covered with D. covers
答案：______
练习2：汉译英
毛乌素沙漠完全被荒沙覆盖。
译文：________________________________________
【易错提示】Most of + 名词的主谓一致
Most of + 单数名词/不可数名词 → 谓语动词用单数；Most of + 复数名词 → 谓语动词用复数。本题中 Most of the mountain，mountain 为单数名词，故谓语用 is covered with。
