6. 语言点学习 Language Points
语言点一：benefit from
【规则讲解】 benefit from 从……中获益，后接名词、代词或动名词；benefit n. 益处，好处；beneficial adj. 有益的 (be beneficial to 对……有益)。
例句1：Local Kenyans have benefited a lot from the new railway.
例句2：We can all benefit from regular exercise.
例句3：Fresh food is beneficial to our health.
练习：
We can ______ more good habits.
A. benefit from
B. benefit
C. benefit in
D. benefit at
答案：______
You will benefit from ______ (practice) English more.
答案：______
【易错提示】benefit from用法
benefit from中from是介词，后接名词、代词或V-ing。区分：benefit作动词“使受益”，主语是人；beneficial是形容词“有益的”，常用于“be beneficial to”结构。
语言点二：be happy with
【规则讲解】 be happy with 对……感到满意，同义词组：be satisfied with，be pleased with。注意介词用with而非at。
例句1：I'm very happy with the new railway built by our Chinese friends.
例句2：The teacher is happy with the students' progress.
例句3：Are you happy with your new job
练习：
She isn't happy ______ the new dress.
A. with
B. at
C. for
D. in
答案：______
My mother ______ (be) happy with my behaviour just now.
答案：______
【易错提示】be happy with的介词搭配
“对……满意”的几个表达均用介词with：be happy with / be satisfied with / be pleased with。与“be happy”单独使用不同：be happy表示“开心”，be happy with表示“对……满意”。
语言点三：convenient
【规则讲解】 convenient adj. 方便的；常用句型：It is convenient for sb. to do sth. 对某人来说做某事是方便的。名词形式：convenience；反义词：inconvenient。
例句1：It is very convenient and doesn't cost much money.
例句2：It is convenient for me to take the train to work.
例句3：You can pay the bill at your convenience.
练习：
My neighbourhood is very ______ because it's near the shopping center and the bus station.
A. smart
B. peaceful
C. friendly
D. convenient
答案：______
It isn't convenient ______ him ______ get up so early.
A. for; to
B. to; for
C. for; /
D. of; to
答案：______
【易错提示】convenient的主语限制
convenient的主语不能是人！不能说I am convenient，而要用“It is convenient for sb.”结构。“It is convenient for sb. to do sth.”是最常用的表达。“at your convenience”表示“在你方便的时候”。
