【重点句型】
1.　Dr.Yuan Longping grows what is called super hybrid rice.(P10)
袁隆平博士种植的是被称为“超级杂交水稻”的稻种。
【考点】　what is/was called或what people call/called是习惯用法，意为“所谓的；人们常说的”，相当于so­called。其中引导词what在此句中相当于“the＋n.＋that”结构。本句可改为Dr.Yuan Longping grows the rice that is called super hybrid rice.。
①At last，they reached what is called the New America.最终，他们到达现在被称为新美洲大陆的地方。
②He graduated from what was called a key high school.他毕业于一所所谓的重点高中。

2.　He would much rather keep time for his hobbies.(P10)他更愿把时间花在自己的业余爱好上。
　【考点】 would rather宁愿、宁可，没有人称和数的变化，全部的人称一律用would rather。

②—Do you mind if I smoke？你介意我抽烟吗？
—Well，I’d rather (that) you didn’t.嗯，最好别抽。

【温馨提示】　would rather＋从句，意为“宁愿”，此时从句中要用虚拟语气。表示与现在或将来事实相反，从句用一般过去时；表示与过去事实相反，从句用过去完成时。
3. In 1973, he became the first agricultural pioneer in the world to grow rice that has a high output. 1973年，他成为世界上第一位种植高产水稻的农业先锋。
【考点】不定式放在表示次序的词the first, the last, the best以及the only, the very, the right等词后面, 且这些词与动词不定式有规律上的主谓关系，结构为：the first/last/best/only/very/right ...+n. + to do sth.表示“第一个/最终一个/最好的一个/唯一的/恰好的/合适的……做某事的人/物”。
He is always the first to come and the last to leave. 他总是第一个来并且最终一个离开。

【重点语法】
1． 作主语. 动名词作主语时，句子有两种形式：
①动名词直接置于句首主语的位置上。
1) Playing tricks on others is something we should never do．戏弄别人是我们万万不能干的.
2) Learning new words is very important for me．学习新单词对我来说格外重要。
3）Talking is easier than doing. 说比做简洁
②用形式主语it，把真正的主语——动名词结构移置句尾。但这种句子形式有确定的限制，作表语的只能是某些形容词或少数名词，如useful，useless，good，fun；no use，worth等。如：
1) It’s worth making the effort．这事值得去做。
2) It is useless trying to argue with Shylock．和夏洛克争辩是没有什么用的。
Is it any good trying to explain?想再解释一次有好处吗?
4) It is pleasant working with you．跟你在一起工作是令人快活的。
常用-ing形式作主语的句型有：
It +be +a waste of time doing 做……是铺张时间的
It is/was no good/use doing 做……是没用处的
It is/was hardly/scarcely worth doing 做……不值得
It is/was worth/worthwhile doing 做……是值得的
There is no doing 无法……， 不允许……
There is no sense in doing 做……没有道理
There is/was no use doing 干……无意义
There is/was nothing worse than doing 没有比……更糟的
There is/was no point doing 干……无意义
There is no point doing such a silly thing. 做这件傻事毫无意义。
There is no point doing such a silly thing
留意：There is no need to do sth 干……没必要，在此句式中to do 不行换为doing..
There is no need to tell her. 没有必要告知她。
There is no need to tell her
而在It’s important … / It’s necessary … / It’s advisable … / It’s essential … / It’s fitting … 这类句型中，只能用不定式，如：
It’s important to learn foreign languages.
It’s quite necessary to read it many times
2.动名词作宾语有两种状况。
一是有些动词只能后接动名词作宾语；二是有些动词既可后接动名词也可后接不定式作宾语。
①只能后接动名词作宾语的动词，常见的有avoid，consider，enjoy，keep，finish，suggest，dislike，delay，escape，cannot help，imagine，mind，miss，practise，cannot stand，cannot help等。如：
1)I can’t avoid going．我不能不去。
2) Have you considered looking for one special friend？你是否考虑过找一位挚友?
这类动词还有：excuse，fancy，give up，put off，risk等。
②既可接动名词又可接不定式作宾语的动词，常见的有：begin，start，continue，like，love，prefer，by，mean，forget，remember，hate等。
A．在like，love，hate，prefer等动词之后，用-ing或不定式意义上没有什么不同，只是侧重点有些不同，动名词表示泛指的动作，不定式表示具体的一次性动作。
B．在begin/start，continue之后，用动名词和不定式，意义无甚区分，尤其是当主语是人的时候。
C．在动词forget，remember，regret之后，用动名词与不定式意义不同。动名词表示动作先于谓语发生，不定式表示后于谓语动作，如：
I remember posting the letter．
我记得我已把信寄了。
2) I’ll remember to post the letter．
我会记着去寄信的。
D．在try，mean之后，意义各不相同，如try to do (设法)，try doing (试试)，mean to do (打算，有意要做)，mean doing (意思是，意味着)。如：
1) We must try to get everything done in time．我们必需设法准时把一切搞好。
2)Let’s try doing the working in some other way．我们用别的方法做这工作试试。
．动词+介词+动名词，如：
1) I insist on taking proper food fort his expedition．我坚持为这次出行带足需要的食物。
下列短语中的to都是介词，所以后面跟名词或-ing形式：devote to，object to，pay attention to，get down to，lead to, look forward to，stick to，be used to等
