“need”双重角色的用法及其区别
“need”既可以作情态动词,也可以作实义动词,但是它们的用法不同.
1）need用作情态动词的时候表示“需要”或“必须”,通常用于否定句和疑问句.
疑问句式：need +主语+动词原形+...
eg.Need you go home right now?
否定句：主语+ needn't +动词原形+...
eg:He needn't worry about it．
You needn't do the work now.
2而作为实义动词时,适用于肯定、疑问、否定皆可.
通常用法是：
肯定句式：
人＋need ＋to do
物＋need ＋doing
物＋need ＋to be done
疑问句式：Do + 主语 + need + to do sth/doing sth/to be done?
否定句直接在need前边加don't或者doesnt就可以.
另外,“need”后还可以直接跟名词.请看下面的例子：
1．We need to collect the parcel before we leave for England．去英国之前,我们需要收拾好行李.
2．We need to tell him the truth．我们需要告诉他真相.
3．My car needs repairing．我的汽车需要修理.
4．The flowers need watering．这些花需要浇水.
5．His leather shoes needs to be mended．他的皮鞋需要修补.
6．Her room needs cleaning．她的房间需要打扫.
7．It is aquestion that needs very careful consideraton．这是一个需要慎重考虑的问题
因此第一题答案正如楼上所说,选C.
2.c money为不可数名词
3.How will
4.c these years 是时间段,应该用完时,强调对结果及其影响.
5.d pay for 固定搭配
6.b,反义疑问句
7.Either ,or ( both...and不行,其表示两者都,但题中是表其中一个.）
8.a in south of Bejing 表示在北京以南,in the south of Bejing表示在北京的南面
如：
in the south of China指中国南部（比如广东省）
in south of China指在中国以南（比如新加坡）
