【点评】本题重点考查了常用短语take care of和spend…(in)doing sth及一些常用句式。易错点是含有含有特殊疑问词的宾语从句,注意宾语从句中用陈述语气。解题时注意时态和句式变化。
18.【答案】(1)invite;to
(2)keep;quiet
(3)depends;on

(3)本题考查动词短语depend on含义为“依靠、依赖、取决于”。而且,注意短语作主语看成单数,因此,谓语动词depend on要用第三人称单数形式。(4)本题考查常用句式It be adj (for sb) to do sth,意思为“对某人来说做某事怎么样”。
(5)本题考查固定短语as a result,其含义为“因此,结果…”,后跟句子。
(6)本题考查“越…就越…”的表达形式:The +比较级…,The+比较级….因此,fast用比较级形式faster, much用比较级形式more。
(7)本题考查常用句式It be(not) adj (for sb) to do sth,意思为“对某人来说做某事怎么样”。句中It做形式主语,真正的主语是后面的不定式结构。
【点评】本题重点考查了常用词invite、depend、keep等构成的短语。易错点是句式It be adj (for sb) to do sth和“越…就越…”的表达形式。解此类题时,要先看句意,再确定时态。
