1． He realizes that he has-n’t been a very good friend because he has always been thinking about himself.他认识到他不是一个好朋友，因为他一直都在考虑他自己。 (Unit 1)
解析： “have / has been + doing“是现在完成进行时，主要表示到现在为止的一段时间内动作一直在持续（也可能刚停止）。例如：
1) I’ve been waiting for you for a long time.
2) —Hi, Tracy, you look tired.
—I am tired. I have been painting the living room all day.
2. He also learns that he should have cared more about his friends.他也明白了他本应该多关心他的朋友。 (Unit 1)

1) Jenny should have kept her word. I wonder why she changed her mind.
2) Mr. White should have arrived at 8:30 for the meeting , but he didn’t show up.
其否定式“shouldn’t + have + 动词的过去分词”，则表示“过去本不该做某事而实际上却做了”。例如：
1) We shouldn’t have waited for her because she never came.
2) You shouldn’t have spoken to your mother like that.
3． With so many people communicating in English every day, it will become more and more important to have a good knowledge of English.有这么多的人每天用英语交流，精通英语将会变得越来越重要。(Unit 2)
解析： 本句中使用了“with + 复合宾语”的结构。这种结构在句中多作状语，表伴随、方式、原因等；也可作定语。常见的有以下几种形式：
(1) with + 宾语 + doing / done例如：
I couldn’t do my homework with all that noise going on.
The murderer was brought in, with his right hands tied behind his back.
(2) with + 宾语 + to do例如：
I can’t go out with so much housework to do.
With many things to deal with, he decided not to spend the holiday.
(3) with + 宾语+ 介词短语例如：

Do you know the woman with a baby in her arms?
(4) with + 宾语+ adj. / adv.例如：
He went to sleep with the light on.
Don’t sleep with the windows open.
4. What do you have to consider before you decide which means of transportation you will use? 你决定采用某种交通方式之前得考虑什么？ (Unit 3)
解析： “consider”表“考虑”时，它后面常接名词、代词、动名词、疑问词 + to do。例如：
1) You must consider it / the matter carefully.
2) He is considering moving to the south.
3) Have you considered how to get there?
另外，“consider”还可作“认为”讲，它后面常接（1）that从句(2) 名词、代词 + as / to be / to do / to have done （3） it + adj. + to do sth. 例如：
1) I consider him as my best friend.
2) Charles Babbage is generally considered to have invented the first computer.
3) Do you consider it necessary to go there at once?
5. Before she could move, she heard a loud noise, ... .她还没来得及迈步，就听见一声巨响，……。（(Unit 4)
解析： “before”在这里的意思是“不等……就”；“还没来得及……就”。例如：
1) He had left before I could say ”Thank you “ to him.
2) Someone called me up in the middle of the night, but they hung up before I could answer the phone.
从属连词“before”引导从句时，根据不同情景有较灵活的译法。常见的译法还有：

Be a pupil before you become a teacher.
2） …… （之后）才
It will be months before he is fit for his job.

What she couldn’t understand was why fewer and fewer students showed interest in her lessons. (2000上海)
18. If only they could find a way to get to the room, or whatever it was, behind the wall.要是他们能找到一条通道进入墙壁后面的那个房间或不管是什么就好了。 (Unit 12)

13. I should be home in about ten minutes.大约再过十分钟我就可以到家了。 (Unit 9)
解析： 情态动词“should”在这表示推测，意为“估计应该，按理应当”。例如：
1) It’s nearly seven o’clock. Jack should be here at any moment.
2) We’ve got everything ready. There should be no problem.
14. Having a cellphone also makes us feel safer, since we can call for help in case of an emergency.有手机也可以使我们感到更安全，因为万一遇到紧急情况，我们可以随时呼救。(Unit 9)
解析： “in case of”是介词短语，意为“假设，万一”。例如：
In case of fire, ring the alarm bell. 万一失火立即按警铃。
拓展： “in case”单独使用时，可用作状语。也可引导从句，意为“以免；以防”。例如：
1) It may rain. You’d better take an umbrella in case.
2) John may phone tonight. I don’t want to go out in case he phones.
15. She says that her cellphone helps her do whatever she wants to do and still stay in touch with her parents and friends.她说手机帮助她想做什么就做什么，并且使她可以与父母和朋友随时保持联系。 (Unit 9)
解析： “whatever”在句中引导宾语从句。意为“无论什么”。例如：
1) These wild flowers are so special I would do whatever I can to save them.
2) It’s generally considered unwise to give a child whatever he or she wants.
拓展： 1） “whatever”还可以引导让步状语从句，此时相当于“no matter what”。例如：
Whatever you say, I won’t believe you.
16. Professor Stevenson , who has devoted himself to protecting the milu deer, gave a talk to Chinese college students in Beijing.致力于保护糜鹿的史蒂文森教授在北京给中国大学生作了一次演讲。 (Unit 10)
解析： “devote oneself / one’s life / one’s time ... to”表示“献身于……；专心于……”。其中“to”是介词，后面跟名词、代词或动名词。例如：
She devoted herself to helping the poor.
He devoted his life to the scientific research.
17. What we hear on the radio or see on TV is only a small part of all the wonderful music that is waiting for us.我们在收音机里听到的或在电视上看到的只是所有等待我们欣赏的美妙音乐中的一部分。(Unit 11)
解析： “What we hear on the radio or see on TV”是一个主语从句。“what” 在名词性从句中充当一定成分（主语、宾语或表语）；也有实际意义（所......的东西或事情），不能省略。而连词that在名词性从句中不充当句子成分，也无实际意义，引导宾语从句时一般可以省略。例如：
What he said at the meeting astonished everybody present. (MET 1993)
What she couldn’t understand was why fewer and fewer students showed interest in her lessons. (2000上海)
18. If only they could find a way to get to the room, or whatever it was, behind the wall.要是他们能找到一条通道进入墙壁后面的那个房间或不管是什么就好了。 (Unit 12)
解析： “If only”的意思是“但愿；要是……就好了”。这时句子多用虚拟语气。它的用法同“wish”。例如：
Look at the heavy rain! If only it would stop!
If only I could have been more careful.
