Over here! Dont you remember me? (P11)过来！你不记得我了吗？remember的反义词是forget，两者用法相同，后面可跟名词，动名词或动词不定式。remember/forget doing sth表示“记得/忘记做过某事”，强调事情已经做了。remember/forget to do sth表示“记得/忘记去做某事”，强调事情还未做。I remember posting your letter. 我记得替你寄过信了。They forget locking the door. 他们忘记锁过门了。I remember to post your letter. 我记得替你寄信。They forget to lock the door. 他们忘了锁门。2. Youre Paula, arent you? (P11)你是波拉，对吗？这是一个反意疑问句，表示说话人提出某种情况或看法，询问对方是否同意。知识拓展反意疑问句主要有以下几种类型：(1)主句为肯定陈述句时，附加疑问句为：系动词/情态动词/助动词的否定（缩写）形式+主语。The girl went to school late yesterday, didnt she?昨天那个女孩上学迟到了，是吗？(2)主句为否定陈述句（包括肯定形式中有never, seldom, hardly, few, little, nobody等否定意义的词）时，附加疑问句为：系动词/情态动词/助动词的肯定形式+主语。You have never been to Beijing, have you? 你没有去过北京，是吗？(3)主句为祈使句时，附加疑问句为：will或shall+主语。Open the window, will you? 打开窗户，好吗？Lets go to school, shall we? 我们上学去吧，好吗？3. Wow! People sure change. (P11)哇！人确实是会变的。句中的sure用作副词，意为“确实”，“无疑”。sure一词更常见于以下用法和句型：表示“可以”，“当然”，“没问题”，常用来答应他人的请求，相当于 Yes./OK./Great./Certainly./Of course.Did you have a good trip?旅途愉快吗？Sure./Of course.当然。Would you like to go with us?愿意和我们一起去吗？Sure./Certainly.好啊。be sure about/of意为“确信，对有把握”，后接名词，代词或v-ing形式，表示对客观事物有肯定的认识和判断，主语必须是人。Im sure of passing the examination.我相信我会通过考试。He lives in this building but Im not sure about the room number.他住在这栋楼里，但是房间号码我不太清楚。be sure to意为“一定”，“肯定”，后接不定式，往往表示局外人的推测、评论，主语不一定是人。Its sure to rain tomorrow.明天一定会下雨。She is sure to understand much more than before.她一定比以前懂得更多了。试比较下面两句：The old woman is sure to live to more than ninety.这位老太太肯定可以活到九十多岁。The old woman is sure of living to more than ninety.这位老太太相信自己可以活到九十多岁。be sure to 用于祈使句时，是“务必”，“切望”的意思。Be sure to review the text after class.课后务必复习课文。Be sure to come tomorrow，everyone.大家明天一定要来。be sure接that从句时，意为“认为一定会”，主语必须是人，连词that可以省略。be sure后面还可以接由whether， where, when或who等引导的名词性从句，这时主句通常是否定形式。Im not sure whether I can come tomorrow.我明天是否能来还说不准。Im sure that I can run faster than you.我确信我比你跑得快。5. I go to sleep with my bedroom light on. 我开着卧室的灯睡觉。(1)with my bedroom light on为介词短语，在句中用作状语，表示伴随情况。He walked out of the room with his coat on. 他穿着外套走出了房间。知识拓展“with+名词+介词短语”结构也可用作状语，表示伴随情况。The teacher came in with a book under his arm. 老师腋下夹着一本书走进教室。The poor woman walked through the street with a baby on her back.那可怜的妇女背着一个婴儿，穿过了街道。(2)on在此处是形容词，意为“开着的，接通的”，常见的结构有：be/turn on。Is the light on in the room? 屋里的灯开着吗？No. Its off. 不，关着呢。Turn on the radio, please. Ill listen to the weather report.请打开收音机，我要听天气预报。6. Before I started high school, I used to spend a lot of time playing games with my friends, but I just dont have the time any more. (P14)在上高中之前，我常常花费大量时间和朋友们一起做游戏，但是如今我再也没有这样的时间了。(1)high school相当于middle school,意为“中学”，常指高中。(2)本句中的spend意为“花费”，常用来说明某人买某物花了多少钱或某人花了多少时间做某事，主语通常为人，常见的句子结构有两种：sb spends some money/time on sthShe spends a lot of money on books. 她花很多钱买书。sb spends some money/time in doing sth，其中介词in可以省略。They spent two hours (in) looking for the cat. 他们花了两个小时找那只猫。特别提示take, pay与cost也可以表示“花费”：take意为“花费”，常用形式主语it，真正的主语是动词不定式，常见的句子结构有：“It takes （took）+时间/金钱+动词不定式”（表示“做某事花费了多少时间/金钱”）和“It takes+sb+时间/金钱+动词不定式”（“做某事花费了某人多少时间/金钱”）。Itll take only ten minutes to walk to the supermarket.只要十分钟，就可以走到那家超市。It took Yang Liwei about 21 hours to circle the earth in his spaceship.乘宇宙飞船环绕地球大约花费了杨利伟21个小时。pay的基本意思是“支付”，主语是表示人的名词或代词，常与for连用。How much did you pay for all these books? 这些书你是花多少钱买的？cost也可作“花费”解，其主语是“物”或“事”，常用于sth costs (sb) some money结构。The dictionary cost me 40 yuan. 这本字典花了我40元钱。(3)not.any more意为“不再”，相当于no more，一般用来表示动作或行为的不再发生或重复。They dont use animals to do farm work any more. 他们不再使用牲畜做农活了。7. Now, I dont mind them. (P14)现在我不介意它们了。动词mind的基本含义是“介意，反对”，后面接名词或动名词。He doesnt mind closing the window. 他不介意关掉窗户。知识拓展Would you mind doing.?句型常用来向别人提出请求，对方如果表示介意，就说“Yes”；如果表示不介意、不反对，应说“No, not at all./No, of course not.”。 Would you mind telling me how to remember English words?你介意告诉我如何记英语单词吗？No, not at all. 不，不介意。特别提示mind还可用作名词，表示“思想，主意”。What do you make up your mind to be when you grow up?你长大以后立志要做什么？短语链语never mind不要紧，不介意；keep in mind记住；make up ones mind下决心，下决定；set up ones mind to do sth立志做某事; change ones mind改变主意。8. However, after his fathers death a few years ago, Martins life became much more difficult. (P16)然而，几年以前，在他父亲死后，马丁的生活变得更困难了。本句中的dead意为“死的”，是形容词，表示“死的，无生命的”，常与be动词连用，指死的状态。He is dead, but his name will live in our hearts forever.他虽然死了，但他的名字将永远留在我们心中。Her grandfather has been dead for more than two years. 她的爷爷去世两年多了。特别提示die, dying, death也可以表示“死”。die意为“死亡，断气”，是终止性动词，指生命的结束，强调动作。His mother died two years ago. 他的母亲两年前去世了。dying是die的现在分词，通常作形容词使用，是“要死的”，“垂危的”，“濒临死亡的”的意思。This dog is dying. 这条狗快要死了。death是die的名词，意为“死亡”。It makes me very sad when I think of my little dogs death.当我想起我小狗的死亡时，我很难过。Uint 2知识点测试一.选择填空(10分)( ) 1.

CWhen you watch TV and play video games, you make environment worse! It may seem hard to believe, but its true. When electricity(电)is made, so are greenhouse gases(温室气体).This means that every time you use electricity, you help make global warming worse!Cars are also making global warming worse, because they send lots of greenhouse gases into the air. Global warming may be a big problem,_. People can try to drive their cars as less as possible,or even get ones that run on sunlight!You can also help in many ways. Why not try the following top ideas? Try to use less electricity. Turn off lights, your television, and your computer when youre not using them. Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the amount of greenhouse gases in the air. Dont throw away rubbish. Try to recycle it as much as you can. If rubbish is not recycled, it will rot(腐烂)and make a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers.阅读短文，完成下列任务。（10分）1根据短文补全句子。(1)If we use more electricity, we will help make _.(2)Cars a
