为什么选C？为什么用单数？
2.Last year he bought the house _______.
为什么用cheap，不用cheaply？

A.do they B.need they
选哪个？为
- 1.Only a knife and fork _____ on the table.There is nothing else.
A.are B.are left C.is D.was
选C .在英语中，当不可分割的两个词用在一起时，表示一个整体，谓语用单数.
2.Last year he bought the house _______.
cheap修饰house, 做定语，便宜的房子.不用cheaply，因为如果用cheaply就修饰bought了，便宜的买了，说不通，而且副词也不能修饰名词house.
3.Clever students need never work hard,_____?
A.do they B.need they
选Ｂ．
带情态动词dare或need的反意疑问句，疑问部分常用 need （dare ） +主语。例如：
We need not do it again, need we ? 我们不必重做一遍，是吗？
He dare not say so, dare he? 他不敢这样说，是吗？
当dare, need 为实义动词时，疑问部分用助动词do + 主语。例如：
She doesn't dare to go home alone, does she? 她不敢独自回家，是吗？
4.All of the flowers now raised here have developed from those ______ in the forest.
A.once they grew B.ther grew once C.that once grew D.once grew
that后面引导定语从句，修饰those,Ｄ中没有that,又出现了一个动词grew，这样句子就有了两个动词，语法上说不通．
5.They are likely to travel more and want more education,______,many more jobs are acailable in these services.
题中的acailable写错了，应该是available, 空白处应该是meanwhile,整句意思为：他们有希望去旅游并接受更多的，同时，这些服务的工作都还空缺着．
6.Rorbet is said ______ abroad, but I don't know what country he studied in.
A.to have studied B.to be studying C.to have been studying
选A 据说Rorbet 曾在海外学习，但是我并不知道他在哪个国家学习．
从后面看，studied为过去时，说明Rorbet 现在并不在国外学习了．所以只能选Ａ．其他选项为进行时态，不合题意．
