如:Washing the car seems to be your main hobby. 擦洗汽车似乎是你的主要爱好。

介词but后的动词带不带to主要看前面有没有do

介词but后的动词带不带to主要看前面有没有do请看看下面这道题:He did nothing but __________ a letter.A. writeB. to writeC. writingD. to have written此题应选A。
一般说来,介词后接动词通常应是动名词。
但是介词but(except也一样)却比较特殊,其后接动词时,可以接不定式,并且这个不定式可以带to也可以不带to:1. 当其前的谓语含有实义动词do(可以是各种形式)时,其后的不定式通常不带to:She will do anything but play chess. 她除了下棋外什么都愿干。
He did nothing all day except watch TV. 他一整天除了看电视什么也没做。
2. 当其前的谓语没有某种形式的实义动词do时,其后的不定式通常要带to:They had no choice but to obey. 他们别无选择只有服从。
He wanted nothing but to stay here. 他除了想呆在这里外,其他什么也不想。
We have no choice but to arrive late. 除了迟到以外,我们并无选择。
We have no choice but to turn back. 没办法,我们只有回去。
You have no choice but to give up. 你别无选择,只能投降。
3. 当其前含有实义动词do但不是用作谓语时,其后的不定式带不带to均可,但以不带to 为多见:There’s nothing to do but (to) leave.只好离开。
There was nothing to do but (to) wait. 除了等没有其他的办法。
At present I can do nothing but wait. 目前, 我只好等待。

不定式的用法

不定式的用法一、考点、热点回顾(一)不定式的用法1.不定式作主语⑴原则上,可用动词不定式直接作句子的主语,通常用it 作句子的形式主语,而把不定式移到后面,形成“It + 谓语… + 动词不定式…”的句型。
如:To catch the 5:00 bus early in the morning is not a good idea.It is not a good idea to catch the 5:00 bus early in the morning.To learn a foreign language well takes painstaking efforts.It takes painstaking efforts to learn a foreign language well.⑵若要说明不定式的动作的执行者,可以在不定式前面加上“for + 名词或代词”结构,或是“of + 名词或代词”结构。
It is a great pleasure for me to talk with him. It is very kind of you to help me .⑶可用于“of + 名词/代词 + 动词不定式”结构中作主语补足语的形容词是指那些可以表示人或事物的性质或品质的好坏的形容词。
这些词如:careful,cruel,foolish,bold,brave,good,honest,kind,rude,polite,nice,stupid,selfish,silly,wicked,wise,thoughtful,wrong等。
2.不定式作宾语不定式作宾语有两种情况:一是及物动词后直接跟带to的不定式,二是“动词+疑问词+带to的不定式”。
⑴“动词+带to的不定式”结构:常见的以不定式作宾语的动词有afford,appear,agree,ask,believe,decide,demand,desire,fail,hope,intend,learn,mean,offer,promise,refuse,wish等。
