作者:严建英 1. [原文]Have you ever watched someone surf? (L. 6)surf是动词,在这里怎么用原形? [精析] surf是省去to 的动词不定式,在这里作感官动词watch的宾语补足语。类似用法还有,感官动词look at, see, listen to, hear, 使役动词let, have,make等,后都可以接省去to的不定式作宾补。 2. [原文] Now it is enjoyed by people all over the world. (L. 6) is enjoyed是什么谓语形式?all over是什么用法? [精析]is enjoyed是被动语态形式。当主语为动作的承受者时,谓语要用被动语态形式,即be + 过去分词形式。这部分内容在今后还要学到。 all over是“全部、浑身、在各地”的意思,可单独使用,也可在其后接相应的词语。例如: People all over the world love peace.全世界的人民都热爱和平。 He is wet all over.他全身都湿了。 all over the world 也可以用all the world, the whole world 来表示,但一定要注意冠词的位置。用all 时,冠词放在all之后,用whole时,冠词放在whole之前。 3. [原文] Every year...attract large numbers of tourists to the islands. (L. 6) large numbers of与a large number of 有区别吗? [精析]没有。这两个短语都表示“许多”的意思,可以互换。如:Large numbers of / A large number of people came to the meeting from all over the country. 许多来自全国各地的人参加了会议。但是a number of / numbers of 与the number of是有区别的。作主语时,前者后接复数名词,谓语用复数形式;后者意思是“为……的总数”,后接复数名词,但谓语要用单数。试比较: A number of students are playing in the playground.许多学生在操场上玩。 The number of students in the playground is about one hundred.操场上的学生(数量)大约有一百人。 4. [原文] For example, Jake Booth, a 21-year-old man, gave up his job in San Francisco a year ago. (L. 6) 21-year-old中的year怎么不加s? [精析] 21-year-old是由数词 + 名词 + 形容词构成的复合形容词,其中year不可以用复数形式,词与词之间用连字号。试比较: He is a 15-year-old boy.他是一个15岁的男孩。 The boy is 15 years old.这个男孩15岁。 另外,句中give up意思是“放弃”,作及物动词,后可以接动名词;也可以接代词,用宾格放于up之前。也可用作不及物动词。例如: You should give up smoking. I gave it up last year.你应该戒烟。我去年就戒掉了。 She doesn't give up easily.她做任何事情都不会轻易放弃。 5. [原文] Although I haven't got a very good job, surfing keeps me very fit.( L. 6) although与though用法相同吗? [精析] 有共同之处,也有不同点。两都可用来引导让步状语从句,表示汉语的“虽然……但是……”。但不能说although / 高频考点解读(Unit 2) 作者:杜倩 【考点一】 No matter ____you come, you will always be welcome. A. what B. how C. when D. whether [思路解析]本题译为:“无论你什么时候来,你都是受欢迎的。”应该用when。所以本题答案为C。 [知识拓展] No matter who (what, how, why, when, where, if, whether,how many,how much...)无论谁(什么,怎么,为什么,什么时候,哪里,是否,多少……)在句中作让步状语。可放句首,也可放句末。如: a) You can' t go in, no matter who you are. 不管你是谁,都不能进去。 b) Don' t trust him, no matter what he says or does.不管他说什么或做什么,你都不要相信他。 c) No matter where you go, we'1l always be together. 不管你去哪里,我都和你在一起。 d) Mary always got to school on time, no matter if she went without breakfast. 玛丽不管是否吃了早饭,她都是准时赶到学校。 【考点二】 He has been to Beijing twice. (对划线部分提问) _________has he been to Beijing? A. How long B. How often C. How soon D. How many times [思路解析] 本句的意思是“他去过北京两次”,对次数提问,疑问词应用how many times,故本题答案为D。 [知识拓展] 1) how often是对动作发生的频率进行提问。如: —How often do you have to take the medicine?这药需要多久服一次? —Three times a day. 日服三次。 2) how long表示动作持续的时间。如: —How long have you studied here? 你在这儿学习多久了? —I have studied here for nearly 3 years .我在这儿学习近3年了。 3) how soon表示再过多久,一般用将来时态。如: —How soon will you go to Beijing? 你再过多久去北京? —I'll go to Beijing in two weeks.再过两周我就去北京了。 【考点三】 —Who jumps_________in your class? —Li Ming. He cleared the 1.6 meter mark last week. A. high B. highest C. the most highly D. tallest [思路解析] high表示“高的,高地”,既可以作形容词又可以作副词。highly adv. 表示“高度地,极为赞许”等,在这里表示跳得高,要用 high,又根据in the class所以用最高级,选B。 [知识拓展] think highly of somebody 意思是“高度评价某人”,speak highly of somebody意思是“称赞某人”。tall主要用来表示形容人或物的高低。 【考点四】 It is dark, but they go on_________. They never usually work so late, though they worked late last night. A. work B. to work C. worked D. working [思路解析] go on doing sth.意为“继续做某事”,go on to do sth.意为“接着做另外一件事”。根据题意,本题答案为D。 [知识拓展] 1) go on doing sth.是“继续做同一件事情,可能中间有间断”。如: I'll stop here. Please go on reading. 我就说到这儿,请接着读吧。(老师在学生读的过程中插话) 2) “继续做某事”还可以用go on with sth. 来表示。如: Go on with your work. 继续工作。 3) go on to do sth.通常表示“接着做另一件事”。如: Stop writing now and go on to read the next passage. 别写了,接着读下一段。 |
