二、重点单词
【单词学习】
1. describe v. 描述
describe 意为“描述”，及物动词，其后可跟以下形式的宾语：
（1）可跟名词或代词作宾语。
Can you describe it? 你能把它描述一下吗?
（2）可跟疑问词引导的宾语从句。
They asked me to describe how it happened. 他们要我把所发生的事情描述出来。
（3）describe sth. to/ for sb. 向某人描述某事
Can you describe to /for me what you saw? 你能将你所见到的情况描述给我听听吗?
（4）describe…as…“把……形容为（说成是）……”。
He described himself as a doctor. 他自称是医生。
describe sth. to/ for sb. 或describe to/ for sb. Sth. 向某人描述某事
Can you?describe?him me?
A. for B. with C. as D. on
答案：A
思路分析：句意:你能向我描述一下他的样子吗？describe sth. to/ for sb.向某人描述某事。故选A。
2. second n. 秒
second 为可数名词，意为“秒”。
There are 60 seconds in one minute. 1分钟有60秒。
常考second 的名词复数形式及作序数词时常与冠词the连用。
second作序数词，意为“第二”，常与定冠词the 连用。如：
She was the second to arrive.她是第二个到达的。
－I hear your friend is visiting San Ya again. Is it the first time for him?
－Yes, and he will come for time next spring.
A. a third B. a second C. the third D. the second
答案：B
思路分析：考查序数词用法。本句意为“我听说你朋友来三亚了，这是他第一次来吗？”“是的，明年春天他将再一次来。”a second time 指再次，又一次，不表示顺序；the second time 第二次，强调顺序。
3. return v. 归还，拿回
return为及物动词，意为“归还”，相当于“give back”。常用句型：return sb. sth.相当于 return sth. to sb. 意为“将某物归还某人”。
Don’t forget to return my book. 别忘了还我的书。
常考句型：return sb. sth.相当于 return sth. to sb. 意为“将某物归还某人”。
“返回”，相当于“go back / get back / come back.”当“返回”讲时是不及物动词，先加to才可再加地点。Ann will visit you when she returns to London. 安返回伦敦后将去看望你。
return 不与back连用。
My cousin gave up the chance of working abroad and his hometown.
A. returned back B. returned C. returned to D. returned back to
答案：C
思路分析：return 作“返回”讲时，为不及物动词，后接to加地点名词，且后面不跟back，故选C。
4. possible adj. 可能的
possible为形容词，“可能的”，多用于“It is possible that……”表示某事是有可能的；“It is （not） possible to do sth.”表示做某事是可能的。possible一般不用人作主语。
It is possible to get there by bus.
可以乘公共汽车到那里。
常考句型：“It is （not） possible to do sth.”表示做某事是（不）可能的。
as….as possible 尽可能的….
如：Please make your decision as soon as possible. 请尽快做决定。
The bridge enables people to get to the island in less than an hour. The underlined part means “____ ___”.
A. makes it safe for B. makes it possible for
C. makes it necessary for D. makes it enjoyable for
答案：B
思路分析：题意：这桥能使人们不到一小时就到达那个小岛上。enable“能够”，故选B。
5. wood n. 木头
wood作“木头”讲时为不可数名词。
Their dishes were made of wood.
他们的盘子是木制的。
wood也可作可数名词，意为“树林；林地”。in the woods“树林”。如：
Now and then we heard shots in the woods. 我们不时听到森林里传来的枪声。
用适当形式填空。
The chairs are made of （木头）.
答案：wood
6. start v. 开始; n. 开头；开端
（1）start 作及物动词，意为“开始，着手”，后接名词、代词、动词不定式，动名词作宾语。
It started to rain. 下起雨来了。
Lily started laughing. 莉莉开始笑起来。
（2）start作名词，意为“开头；开端”。at the start of 意为“在……的开端”，from start to finish意为“从头到尾”。
The trip was relaxing from start to finish. 那次旅行从始至终都令人放松。
常考start doing sth.或start to do sth. 开始做某事。或at the start of…等于at the beginning of….“在……的开端”
start还可以作及物动词，“创建；创办；开办”。如：A boy started a “rock and roll”group.一个男孩创建了一个摇滚乐队。
－Dad, I’ve got an “A” in the math exam.
－Great. And I’m sure you will do better, because this is a good _________.
A. report B. result C. start D. skill
答案：C
思路分析：A项意为“报告”；B项意为“结果”；C项意为“开始”；D项意为“技能；技术”。 句意为“爸爸，这次数学测试我得了A”“很好。我确信你会做得更好，因为这是一个好的_______________”。根据语境可知，此空应填start,故选C。
即学即练：
*1. His parents couldn’t _ _ if they would buy a secondhand car.
A. describe B. discover C. decide D. disappear
答案：C
思路分析：题意：他的父母决定是否买个二手汽车。describe描述 ; discover发现; decide决定; disappear消失。故选C。
**2. Avatar（《阿凡达》）is such _________ wonderful science fiction movie that I want to see it _________ second time．
A. a, a??? ???????????? B. a, the??? ?????????????? C. ／, the ?????????? D. ／, a
答案：A
思路分析：第一空根据such + a/an + adj. + n. + that结构可以得知此处应该使用冠词a，第二空指“又一，另一”应该使用冠词a来表示，所以答案为A项。
3. Next?month，my?father?__ _?to?China?from?America.
A. returns?? B.?is?returning?? C.?is going?to?return?? D.?would?return

**4. －How long have you China?

A. come back B. returned C. left D. been away from
