英语非谓语的几个小问题

1题解析如下:
rather than 作为并列连词用法很杂,需掌握的是以下两种基本情况：
A.rather than 与would连用时
构成“would rather...than...”句式,表示主观愿望意思是“宁愿……而不愿…（与此题无关 略）
B.rather than 不与would连用时
表示客观事实,意为“是……而不是……
(1)、接名词
He is an explorer "rather than" a sailor. 与其说他是一个海员,不如说他是一个探险者.
(2)、接代词
You "rather than" I are going to go camping. 是你而不是我要去要野营.
(3)、接动名词
She enjoys singing "rather than" dancing. 她喜欢唱歌,而不喜欢跳舞.
(4)、接形容词
The sweater she bought was beautiful "rather than" cheap. 与其说她买的这件羊毛衫便宜不如说它漂亮.
(5)、接谓语动词
She telephoned "rather than" wrote. 她打了电话,而没有写信.
(6)、接动词不定式
I decided to write "rather than" telephone. 我决定写信而不打电话（rather than 连接不定式一般省略to)
(7)、接介词短语
We will have the meeting in the classroom "rather than" in the great hall. 我们是在教室里开会,不是在大厅里.
(8)、接分句
We should help him "rather than" he should help us. 是我们应该帮助他而不是他应该帮助我们.
2题解析如下:
使役动词有四个:make,have,let,bid, 后面接原形动词.也有语法书把help 当作使役动词.不过help即可以接不定式也可以接原形算是半个使役动词吧.
Get 也可以表“叫/让."但不是使役动词 后面得跟不定式作宾补. 有的人把get例为使役动词后面却让它跟不定式,这不是以已之矛攻已之盾吗!
3题解析如下:
Know better than+不定式 习惯用法 译：应该知道不该······
1. You should know better than to go swimming right after eating. 你应该知道饭后不能立即去游泳
2. I know better than to lend him any money to gamble. 我知道不能借钱给他去赌博.
此是固定用法.
但如果按提问者的答题思路解析如下:
如果把"better"看成是"well"的比较级修饰动词Know.
那么其比较形式如下：
He knows a silly thing better than he does.
祝学习进步!
