1 B in great demand 是固定搭配,lack 做名词or 动词时用法只有几个,lack sth.,lack of sth,lacking in sth.
2 B strong 作为adj.只有如下几种意思,adj.强壮的；擅长的；坚强的；牢固的,不可以来修饰头痛
3 A approach 只与介词to 搭配,同学,这需要记住,是最基本的用法
4 B nothing 是不定代词,后面要用动词单数形式.而且none的意思有没有人；没有任何东西；一个也没有,所以要选择B
5 A 这个题其实有两个考点,一是the+ n.+n.与the +n.+the +n.的区分,另一个就是tense.the following week 明显是表示将来,所以选择A
6 B 这个通过翻译就可以知道,其中in honor of 向…致敬,向…表示敬意；为庆祝…；in terms of 是在…方面
7 A 句子的前后部分用逗号隔开,所以不用with
8 B carry out vt.施行,实现；put away 放弃
9 B 题中已经说过是2008年,所以不用the year
10 B ask for 的主语主要是人,而且这个场合更正式一些,所以要用call for
11 A 就像so that 句型一样,需要记住
12 B 楼主,我看了下你似乎这道题有疑问,我们试着分析一下,如果选A,为什么不对.首先,选A你觉得是个事实,可是如果真的选择A的话,那就是说he was operated on at once 是正确的,那么the young man ( )badly injured 是在was operated 之前,所以得用过去完成时,可是这与题中给的the young man was badly injured 相违背,所以从反推的角度来讲,不选择A.如果我们选择B,那么翻译过来语法,语义都是通顺,可以理解的,所以选择B
13 A 如果选择B,前后主语不一致,除非用that 将前后两句连接
14 B break down 崩溃,抛锚；break off中断
