Parents should not be too strict with teenagers. 父母不应该对青少年太严格。重点语法1. 情态动词的被动语态,如should be allowed的用法。 重难点及考点解析Section A1. Teenagers should be allowed to go out with their friends every night.(P18)(1)should be allowed to do sth. 意为“应当被允许做某事”,为情态动词的被动语态。该结构的否定句句式是在should后面加not,而一般疑问句句式则是将should提到居首位置。如: Kid should not be allowed to drink. 小孩不应该被允许喝酒。(2) allow动词“允许”。用法如下:allow (doing)sth. 允许(做)某事。如:We dont allow to eat in the classroom. 我们不允许在教室吃饭。allow sb. to do sth. 允许某人做某事。如:My parents dont allow me to go out at night. 我父母不允许我晚上出去。allow sb. sth. 给予某人某物(尤指钱或时间),让某人拥有或带有某物。如:He allows his son too much money. 他给他儿子的钱太多。2. Sixteen-year-olds should be allowed to get their ear pierced. 16青少年应该被允许穿耳洞。(P18)(1) sixteen-year-olds是合成名词,意为“16岁的青少年”,同义短语有:sixteen-year-old kids, kids of sixteen(year old)等。(2) Get their ears pierced 为“get/have+sth.+过去分词“结构,表示“叫/让/请别人做某事”,一般自己不参加。3. I dont think sixteen-year-olds should be allowed to drive. 我认为16岁的青少年不应该别允许开车。(P18)(1)在本句中,宾语从句的否定句not转移到了主句的谓语动词之前,我们称之为否定前移。如: I dont think you can say the words like that. () I think you cannot say the words like that. ()(2) 联想:否定转移的五个常用词suppose(猜想) imagine(想象) believe(相信) think (认为) expect(期待)4. They arent serious enough. 他们不够严肃认真。(P18)(1) enough 在该句中是副词,修饰形容词serious,意为“足够认真的”。又如: The water in the sea is warm enough to swim to . 海水足够暖和,能在里面游泳。(2) enough居无定所作形容词,意为“充足的,足够的”,它一般位于所修饰的名词前。如:I have enough money to buy a color TV set.我有足够的钱去买一台彩电。 作副词,意为“充足地,足够地”,它位于所修饰的形容词、副词或动词的后面,常与不定式和介词for连用。如:Tom is not old enough to go to school. 汤姆年纪不够大,不能去上学。5. He should stop wearing that silly earring. 他不应该再戴那副傻气的耳环了。(P19)(1) stop wearing 意为“停止穿/戴”。动词短语stop doing.用于表示“停止做某事”。如: We the boy saw his mother, he stopped crying. 当这个男孩看见他妈妈时,他停止了哭泣。(2) stop用法如下: Our teacher is coming. Please stop talking.老师来了,不要讲话了。 Whats happening? Lets have a look.发生了什么?让我们去看一看。 We must stop kids from swimming here.我们必须阻止孩子在此游泳。 (3) silly是形容词,意为“愚蠢的”。如: Its silly of you to do like that. 你那么做是愚蠢的。(4) 辨析silly, foolish 和 stupid. 词语用法例句silly指头脑简单,傻头傻脑或令人发笑,相当于汉语的“傻”。You are silly to trust him. 你真傻竟相信了他。foolish通常指无头脑,缺乏知识或判断力,相当汉语的“愚蠢”。He is foolish to throw away such a chance. 他真纯,丢掉这样一个机会。stupid指智力、理解力或学习能力很差,相当于汉语的“笨”。He is very stupid in learning maths. 他学数学很笨。6. They talk instead of doing homework. 他们聊天而不做作业。(P19)(1)instead of 为介词短语,后常跟名词、代词和动名词等。如:Instead of lending a hand, he laughed at us. 他不仅不帮我们,反而嘲笑我们。(2) 辨析instead 和 instead of词语用法例句instead副词,位于句首或句末。He is too busy, so let me go instead. 他太忙,让我替他去吧。instead of 介词短语,后接名词、代词和动名词,位于句中。Mr Lin walked to school instead of taking a bus. 林老师走着去学校,没有坐公共汽车。7. We have a lot of rules at my house. 在我家我们有很多规矩。 So do we. 我们也是。(P20)(1) So do we. 是倒装句,结构为“so+do/have/be/will/can.+主语”,该句式表示前面所说的情况也适合另一个人或物,翻译为“.也是如此”。需注意该句式用于前后两句的主语不是同一个人或物。如: Kate likes oranges. So does Lucy. 凯特喜欢橘子,露西也喜欢。(2) “so+主语+do/have/be/will/can.”, 为自然语序,意为“.确实如此”,表示赞同、肯定或强调前面所说的情况。注意前后两部分的主语是同一个人或物。如: Bill left his key at home. 比尔把钥匙忘在家里了。 So he did. 是的,确实如此。8. .but I have to be home by 10:00 pm. 但我在晚上10点之前必须回家。(P20)(1) be home意为“在家里”,相当于be at home. 如: Is your mother at home, Lily? 丽丽,你妈妈在家吗?(2) by 10:00 pm. 意为“晚上十点之前”。 by 在这儿是介词,表示“不迟于,在.之前”。如: We had to get there by evening. 我们
