如：Computers are made in this factory. (计算机生产于这家工厂。) / Where are they (他们在哪儿) / Does the boy like staying home (这个男孩喜欢呆在家里吗)
(7)主语与谓语必须保持单、复数的一致, 而谓语与表语或宾语之间没有这一要求。
Neither Jim nor Rose has passed the exam. (Jim和Rose都没有通过考试。)
/ The Chinese people are a hardworking and brave people. (中华民族是一个勤劳勇敢的民族。)
2、谓语：
(1)由“不及物动词”、“及物动词+宾语”或“系动词+表语”等构成,说明主语所表示的人物“干什么”或“怎么样”。如：
He travelled in space for the first time.(他首次在太空旅行。) / Who teaches you English this year(今年谁教你们的英语) / The pizza has gone bad. (那块烤馅饼已经变坏。) /
(2)谓语动词必须反映出人称、单复数、时态等信息,
谓语动词往往由下列词语依序排列构成：［情态动词］+［时态助动词］+［语态助动词］+［主要动词］(不一定全部出现)。
(见动词的时态和语态构成表) 记住：谓语部分第一个动词往往是变形动词。如：
I am sorry I am making so much noise but I have to. (对不起我发出了太大的声音但是只能这样。)
/ He can’t have finished reading the 800-page-long novel. (他不可能读完了那本长达800页的小说。)
/ Something must be done to stop the fowl flu from spreading out. (该采取措施防止 禽流感蔓延。)
二、不定式 一、作主语 不定式作主语
动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。如：
To get there by bike will take us half an hour.
(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如：
①It＋be＋名词＋to do
It's our duty to take good care of the old. ②It takes sb+some time+to do
How long did it take you to finish the work 不定式作宾语
①以下动词后，只能跟不定式作宾语。如：agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,long,
manage,offer,plan,prepare,pretend,promise,refuse,wish等， 这些词大部分可接that引导的从句。如： I decided to ask for my money back.
I decided that I would ask for my money back.
When our visit to the farm was over,we expected to startback on foot.
When our visit to the farm was over, we expected that wewould start back on foot.
②当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，
即：主语＋动 词＋it＋补语＋to do句式。如：
We think it quite important for us to learn a foreignlanguage well. He feels it his duty to help the poor. ③介词but,except,besides+to do(do)
在这种句型中，如介词前有动词do，后面应接不带to的不定式；如无do，则接to不定式，
即带do不带to， 带to不带do。如：
The enemy soldiers had no choice but to give in. On Sunday afternoon I had nothing to do but watch TV
It is +adj.+ to do sth 句型
It is difficult for us to finish writing the compositionin a quarter of an hour.
④It＋be＋形容词＋of sb＋to do
It is stupid of you to write down everything the teachersays. ⑤It seems(appears)＋形容词＋to do It seemed impossible to save money.
在句型③中，常用表示客观情况的形容词，如：difficult,easy,hard,important, impossible,necessary 等； 在

，
常
用
careless,clever,good,foolish,honest,kind,lazy,nice,right,silly, stupid,wise等 表示赞扬或批评的词。在不定式前的sb，可看作其逻辑主语。
这一句式有时相当于Sb is＋形容词＋to do句式 ， 如：It'skind of you to help me with my English. =You are kind to helpme with my English. 2.动词+to do（作宾语）
动词不定式做宾语其实你只要把不定式(to do sth)看成一个名词即可,
