动词的语态：
语态有两种：主动语态和被动语态。

主语是动作的发出者为主动语态；主语是动作的承受者为被动语态。

〔1〕假设宾语补足语是不带to的不定式，变为被动语态时，该不定式前要加“to〞。

此类动词为感官动词。

feel, hear, help, listen to, look at, make, observe, see, notice, watch
The teacher made me go out of the classroom.
I was made to go out of the classroom 〔by the teacher〕.
We saw him play football on the playground.
He was seen to play football on the playground.
〔2〕情态动词+ be +过去分词，构成被动语态。

Coal can be used to produce electricity for agriculture and industry.
1. let 的用法
〔1〕当let后只有一个单音节动词，变被动语态时，可用不带to 的不定式。

They let the strange go.---> The strange was let go.
〔2〕假设let 后宾补较长时，let 通常不用被动语态，而用allow或permit 代替。

The nurse let me go to see my classmate in the hospital.
----> I was allowed / permitted to see my classmate in the hospital.
2. 短语动词的被动语态
短语动词是一个整体，不可丢掉后面的介词或副词。

My sister will be taken care of by Grandma.
Such a thing has never been heard of before.
3. 表示“据说〞或“相信〞的词组

It is said that…据说
It is reported that…据报道

It is hoped that…大家希望

It is thought that…大家认为
It is suggested that…据建议
It is taken granted that…被视为当然

spread, stand,
break out, come true, fall asleep, keep silence, lose heart, take place.
After the fire, very little remained of my house.
比拟：rise, fall, happen是不与物动词；raise, seat是与物动词。

〔错〕The accident was happened last week.
〔对〕The accident happened last week.
〔错〕The price has raised.
〔对〕The price has been raised.
〔错〕Please seat.
〔对〕Please be seated.
要想正确地使用被动语态，就须注意哪些动词是与物的，哪些是不与物的。

特别是一词多义的动词往往有两种用法。

解决这一问题唯有在学习过程中多留意积累。

〔2〕不能用于被动语态的与物动词或动词短语：
fit, have, hold, marry, own, wish, cost, notice, watch, agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to

It sounds good.
〔4〕带同源宾语的与物动词，反身代词，相互代词，不能用于被动语态：
die, death, dream, live, life

答案A. need 〔实义〕 +n /to do，need 〔情态〕+ do，当为被动语态时，还可need + doing。

此题考最后一种用法，选A。

如有to be clean 如此也为正确答案。

典：done，“不可能已经〞。

must not do 不可以〔用于一般现在时〕。

过去进展时：
〔1〕概念：表示过去某时正在进展的状态或动作。

〔2〕过去进展时的主要用法是描述一件事发生的背景；一个长动作发生的时候，另一个短动作发生。

三. 阅读理解〈共两篇〉
A
I just returned from a trip to New Jersey. On the way back, I was stopped by
a traffic accident. This accident involved〔牵涉〕a truck carrying a load of dangerous materials that were leaking out. This meant that we weren’t going anywhere for several hours.
After being told by the policeman that we would be sitting there until the cleanup was completed, I got out of the truck to have a rest. Other truck drivers did the same. At one point there were five of us standing by my truck, complaining.
Another truck with two elderly people inside stopped near us. The man, Joe, lowered his window and asked why no one was moving.
Soon we were all talking with this couple. I said that if I had known about this, I would have bought something to drink, for I was becoming thirsty〔口渴〕.The lady, Anna, said that they had plenty of water and sodas in the cooler in their truck and offered everyone something to drink. While she was back there, she said that she also had plenty of food, and asked if we would like a sandwich.
After some urging from Joe, we each agreed to a sandwich. While Anna was making the sandwiches, she was singing like a songbird. Being close to 70, I guessed, she had a remarkable voice.
When she finished making the sandwiches, I saw a Mississippi License〔执照〕plate on the truck. I asked what part of Mississippi they were from. Joe said Biloxi. Knowing that Biloxi had been damaged by Hurricane Katrina, I asked if they had had any damage. Joe said that they had lost almost everything. Everything they had was in the truck.
All of us drivers tried unsuccessfully to pay them for their drinks and sandwiches. Joe said that their son was living around Harrisonburg, Virginia and they were going there. There was a home that was for sale and they were going to start all over there. Starting over at their age, we knew, would not be easy.
These people lost everything except the pictures and some clothes. These wonderful people and some clothes. These wonderful people lost practically everything they owned and still would not accept any money for their food and drinks. Joe said that it was better to give than to receive.

B
Good teachers already know the information that they’re teaching, but they slow down to explain it to you. With their help, you learn much faster than you would on your own. Good teachers take the time to listen to your questions and steer you in the right direction.
One kind of ant does all of these things, too, a new study has found. It is , in fact , the first time that scientists have demonstrated〔证明〕true teaching in an animal other than humans.
“One would have expected to see teaching in chimpanzees〔黑猩猩〕,but the first fairly strong evidence comes from ants, which is surprising and interesting,〞 says Bennett G. Galef Jr. of McMasterUniversity in Hamilton, Ontario.
The tiny ant Temnothorax albipennis lives in small nests among the rocks on the southern coast of England. Previously, researchers had been watching how these ants moved to a new home. They noticed that ants that know the way either carry their friends or run very close in front of them as guides.
The guiding behavior is interesting because ants run much faster when they are alone or even when they are alone or even when they are carrying others.
In their lab, researchers from the University of Bristol in England worked with colonies of Temnothorax albipennis. The researchers had placed sweet food six inches away from the nests.
The study showed that running with another ant took four times as long as running alone, So, just as teachers slow down to help you, ants were slowing down to help others .
Follower ants also tapped their antennae〔触角〕on the backs of the leaders, and the ants adjusted their speeds to stay together. These behaviors show a communication system between teachers and students, just like the questions you ask when you’re confused.
Moreover, after the lesson student ants often managed to find their own shortcuts on the way home. It is a sign that they had learned the neighborhood well during their guided trip to the food. The student ants sometimes even turned into teachers themselves.
All these activities appear to be useful for Temnothorax albipennis. Through careful teaching, ants are able to get others to a food source without having to lay down a scent〔气味〕trail, which might go unnoticed anyway.
1. From the first paragraph,we know asking a teacher for help has ______ advantages.
A. two
B. four
C. five
D. six
2. From the experiment,the scientists have demonstrated<证明>________.
Which is wrong ?
A. with the guiding help, ants can run fast
B.the ants which run faster will stop to help the ones running slowly
C.when moving,the ants always keep in touch
D.a nts listen to each other’s questions and adjust themselves
3. The difference____ between ants and student ants .
A. students often find out different ways to solving questions
B. ants often find out different ways to solving questions
C. ants are clever than students
D. students are more clever than ants
