我宁愿饿死，也不愿用这种方式挣钱。

应用探究

(1)The brave people in the village preferred to die rather than ,and encouraged others to fight more bravely in the anti-Japanese battlefield.

A.to give in;it

B.to give in;which

C.give in;this

D.give in;which

解析：prefer to do sth.rather than do sth.是固定句式，第二个空因为前面出现and说明这是一个并列句，用it代替前面情况。如果没有and，则选择which。

答案：C

(2)I would rather ______ than ask him for his autograph.So I would rather he ______ here as soon as possible.

A.die;leaving

B.died;leaving

C.die;leave

D.die;left

解析：would rather do sth.表示“愿意、宁愿干某事”，would rather后面跟从句时，从句用一般过去时态，故选D。

答案：D

句型转换

(3)The man wearing glasses don’t teach the workers how to do it but learn from them.

答案：but rather

2.It is the second biggest country in the world and as you go eastward,you will see mountains,...

要点提示:

eastward 与eastwards意义相同，副词，意思为“向东”。其他几个表示方向的词语用法与其一致。

典型例句:

A couple traveled eastward.

一对夫妇朝东部旅行。

They are encouraged to walk eastward until the end of the land.

他们被鼓励向东走直到大陆的尽头。

eastward也可以作形容词，意思为“朝东的，向东的”。

小幽默

A stranger wanted to the hospital and was lost in the busy street,“Excuse me,where is the hospital?”he asked a lady.

“Go eastward straight,it is 200 meters.”?

“I see.Thank you.”

After a while,he returned with all the body wet.“You make fun of me,it is a lake not the hospital.”

“There is a bridge on it.”

“But you tell me to go eastward straight.”

3.On the coast north of Vancouver some of the oldest and most beautiful forests in the world still remain.

在温哥华北面的海岸上仍然保存着世界上最古老和最美丽的森林。

要点提示:

(1)remain v.保持;继续存在，仍旧是;用作系动词，后接形容词、名词、分词和介词短语。

(2)当remain作“剩下、留下”讲时可与不定式连用，remaining“剩下的，剩余的”，作定语。

典型例句:

After years of hard work,Tom still remained a worker.

多年的辛劳后，汤姆仍是一名工人。

That old man remained full of energy.

那位老人还是那么精力充沛。

She remained sitting when they came in.

他们进来时，她仍然坐着(没有站起来)。

remain与stay辨析:

remain与stay二者都有“停留，逗留，仍然是，依然是”的意思，表示保持某种状态时可以互换;remain严格说来指东西被取走后或者被破坏后残留下来的东西，或者别人离开之后留下的人，或者待在原地，通常不用进行时态; stay指在某地作短暂停留或者保持某种状态，可以指来访或者做客时暂住。
