Teenagers are too young to make their own decisions. 【解析】1) . agree with 支持， 同意（某人的观点）表示同意某人或某人的意见、想法、分析、解释等 (即持同一观点)：I dont agree with you. 我不同意你的意见。 They agreed with this idea. 他们同意这个想法。I agree what you said just now. 我同意你说的。表示“ (食物、天气、工作等) 对适宜”： The weather does not agree with me. 这种天气对我不适宜。 Hard work does not agree with him. 艰苦的工作对他不适宜。表示“与一致”： A verb must agree with its subject in person and number. 动词必须和它的主语在人称和数方面保持一致。 What he does does not agree with what he says. 他言行不一致。2) . agree to 主要用来表示一方提出一项建议、安排、计划等，另一方同意协作： We agreed to their arrangement. 我们同意了他们的安排。 She agreed to marriage. 她同意结婚。 有时 agree to 也可用来表示“答应”一件自己不愿做的事： I was forced to agree to it, but at heart I didnt quite agree with it. 我被迫答应，但内心并不完全同意。后接 suggestion, plan, proposal 等名词时，与 accept 同义： Do you think he will agree to (=accept) my suggestion? 你认为他会同意 (接受)我的建议吗?其后既可接动词原形 (此时to是不定式符号)，也可接动名词 (一般有逻辑主语，此时 to是介词)： He agreed to go with us. 他同意同我们去。 I never agreed to Mary marrying him. 我从来没同意玛丽嫁给他。3). agree on /upon 主要指双方通过协商而取得一致意见或达成协议： We agreed on the price. 我们就价格达成了一致意见。Both sides agreed on these terms. 双方都同意这些条件。 后接动名词 (=agree to do sth)： He agreed on lending (=to lend) us some money. 他同意借给我们一些钱。 Mary agreed on coming (to come)on Monday. 玛丽同意星期一来。4). 两点用法说明：(1) 后接表示人的名词或代词时，一般只用 agree with。 (2) agree 不能接不定式的复合结构，所以汉语的“同意某人做某事”，不能直译为 agree sb to do sth, 而应根据情况改用其它结构： 正：They agreed to let me go. 或They agreed to my going.他们同意我去。 误：They agreed me to go.()12.

I learned that Mr.Lee had left for the United States.我听说李先生已经去美国了.2) . learn有学会的意思 It takes a long time _(learn )to draw well.学会画画要花很长时间。 这两个动词都作“学习”解，有时可以互换。如： We have learned (或 studied)English for three years. 我们学习英语已经三年了。 learn 往往指通过学习、练习或别人的教授以获得某种知识和技能，侧重学习的成果，有“学会”，“学到”的意思。study 通常指比较深入地学习，含有努力去学的意味，它侧重学习的过程，有“研究”，“钻研”的意思4).learn强调学到了什么，而study强调的是学习本身的过程举个例子：下面句子中的learn和study就是不能互换的: If you hard, youll the language well. 如果你努力学习的话，你会把这门语言学好。(A. learn. B.study)learn from 1. 向学习; 从获得吸取; 从学到( learn sth from sth) She learned everything from me.她什么都是向我学的。Much _(can learn) from a good teacher.从一位好老师那儿能学到很多东西。learn about(v.+prep.)1).获得,学得 gain knowledge about;begin to know (information) about (a subject)learn about sthI have come here to learn about the factorys production.我来了解工厂的生产情况。 learn sth about sthIts no use _(learn) facts about a subject if you dont understand it. 只了解某一学科的知识而不理解,那是毫无用处的.2).得知有关的消息 learn about sb/sthHe the matter before he came.他来以前就听说这件事了。I learned about his death only this morning.今天早上我才听说他去世了。(=hear about/of) How did you learn about our product? 你是怎样了解到我们的产品的?小结：learn, study 共同意思是“学习”。1.learn侧重指通过经验、练习或经别人指教而获得知识或技能,强调结果;而study指专心钻研而获得知识,有探讨和研究的意思,强调学习的过程。 例如: He was studying the map.他正在仔细看地图。2.学习技能(如to swim)只能用learn, 不能用study。eg. I began to learn (ride) a bike at a very early age.3.“向某人学习”只能用learn,不能用study。例如:We should the advanced workers. 我们应该向先进工作者学习。4.“在学习”只能用study,而不能用learn。 例如: Mary is studying at the University.玛丽在这所大学学习。练习：1.我听说他在上海做生意。I learned him to be in business in Shanghai. I learned that he was in business in Shanghai. 析 learn作“听说,知道”解时,后面不能跟以动词不定式充当补足语的复合结构,往往接that从句。2.我听说过那起事故的情况。 I learned the accident. I learned of the accident. 析 learn表示“学习”, learn of表示“获悉,得知”。（=_ _）3.他学会游泳了。 误 He has learned swimming.正 He has learned to swim. 析 learn v-ing强调学习的过程; learn to-v强调学习的结果。4.你在这里还是学到了一点东西。 误 After all, you have learned some knowledge here.正 After all, you have learned something here. 析 knowledge不能与learn连用。13. Do you think we must keep teenagers away from the Internet?【解析】keep.away from 使远离.We must drugs.我们必须让青少年远离毒品。keep sb. from doing sth. 阻止某人做某事 = stop/prevent/keep sb. from doing sth. 阻止某人去做某事用stop/prevent时, 后面的from可要可不要, 但用keep时,from不能省略. 如： We should stop people _(cut) down more trees to protect our environment.( ) This kind of food_ cool, clean and dry according to the instructions. A. should be carried B. must be put C. should be placed D. must be kept14.

This way, when they start (start) working they can manage their own lives.【解析1】manage to do sth. 准确的意思是：成功地做到（了）某事，是有明确结果的。也就是说: sb. managed to do sth.= sb. succeeded in doing sth.拓展 try to do sth. 指的是努力做某事， try doing sth.意思是试着做某事。两者动作能不能“成功”都不太确定。try doing sth.往往隐含着做某事把握不是很大，还有些犹豫，可能会失败，还要重试的意思。16. Can her homework be done tomorrow instead?【解析】instead是副词，在句中充当状语，常用于句首，起连接上下句的作用，通常是上句含有否定的意义，然后用instead引出下句，提出相反的情况，意为：“反而”。【例句】He didnt answer my question. , he asked me another question. 他没有，反而问了我另一个问题。Tom doesnt study hard. Instead, he plays football all day. 汤姆学习不努力，反而整天踢足球。instead也可用在句末，意为“顶替、代替”。【例句】Ann is tired. Let me do that instead. 安累了，就让我来做那件事吧。Han Mei cant help us. Lets ask Lin Tao . 韩梅帮不了我们，咱们请林涛代替吧。【拓展】 instead of 代替；而不是 是一介词短语，表示“代替、而不”。instead of后必须接名词、代词、介词短语或动词-ing形式，而不单独使用。 如：Ill clean the classroom instead of you. 我将替你打扫教室。We went there on foot by bus. 我们没乘公共汽车，而是步行去了那儿。【温馨提示】 instead of和instead 在一定情况下可相互转换。She went swimming tomorrow playing basketball. 她去游泳了，而没有打篮球。=She didnt play basketball.
