罗玉南 1.本单元第49课对话中多次出现了“No,it's not him.”这个句子。 【问】这个句子中的him为什么不用he呢? 【答】人称代词作表语,在非正式英语中(特别是日常会话中)人们已习惯于用其宾格(如me,him等),这种用法很常见。如:—Who is knocking at the door?谁在敲门?—It's me.是我。—Who said that?是谁说的?—I think it was him.我想是他说的。 2.Such was Albert Einstein,a simple man and the 20th century's greatest scientist.爱因斯坦就是这样的人,一个纯朴的人,一位20世纪最伟大的科学家。 【问】请解释句中such的意思和用法。 【答】句中such是代词,用以指代前文所说的情况,意为“这样的人(事)”,它在该句中作表语,such作表语时通常提到句首,形成主谓倒装结构,其谓语动词的数应由such指代的情况而定。如:Such is life.人生就是这样。Such were his words.这就是他讲的话。 3.As a result,it appeared to scientists on earth that the stars had moved.因此,在地球上的科学家看来,恒星好像是移动了。 【问】appear作“好像,似乎”解时,有哪些用法呢? 【答】appear作“好像,似乎”解时,常指人从外表上所得到的印象。有时暗含实质上并非如此的意思,作此意解时,其后可跟不定式、形容词或that从句,接从句时常用it作形式主语,而把真正的主语放到句子后面去。例如:He appears to have many friends.他似乎有很多朋友。Why does she appear so sad?她为何显得如此悲伤?It appears that he won't come tonight.看来他今晚不会来了。It appears to me that they are right.我似乎觉得他们是正确的。 4.教材:That fits the puzzle! 考点:fit的用法。 考例:This straw hat ____ me.(MET'83) A.doesn't fit for B.isn't fitC.doesn't fit D.fits to 透视:此题答案为C。fit表示“合适”,既可作形容词,也可作动词。如果作动词,通常表示衣、帽、鞋等物的大些尺寸、形状等方面的“合适”。如:This jacket fits you well.你穿这茄克衫很合适。如作形容词,通常用于be fit for /to do结构中。如:He is fit for a doctor /to be a doctor.他适合当医生。 延伸:与suit的区别。suit也表示“适合”之意,但它常用来指衣着、款式、颜色等方面的“合适”或“中……之意”。如:That color doesn't suit her。那种颜色不适合她。 再看下题:—This jacket doesn't ____ me.Do you have a larger size? —Yes,but the color is different.Does it _______ you?A.fit;suit B.suit;fit C.fit;fit D.suit;suit(答案:A) 5.教材:Besides his work in physics,he spent a lot of time... 考点:besides /except /except for /except that的区别。 考例1:Does John know any other foreign language ____ French?(MET'89) A.except B.but C.besides D.beside 考例2:The suit fitted him well ____ the color was a little bright.(2000年上海) A.except for B.except thatC.except when D.besides透视:except for +名词/except that +从句表示引述一个相反的细节或原因,因而部分地修正了句子的主要意思,常译成“只不过”。上题答案为B。句意为:那套西服很合他的身,只不过颜色有点亮。 延伸:①except虽然相当于but,但exceptfor≠but for。but for意为“要不是”。如:But for me,he would have died yesterday.②except和but虽为介词,后常接动名词或名词。但在下面的句型中接不定式:have no choice but /except to do(不得不……)。如:Then it has no choice but to lie down. 8.13单元易混词语巧辨 在第13单元出现了几组同义词(组)。对于这些貌合神离的同义词(组),必须加以区分,否则会误用。现将本单元的重点同义词(组)加以对比辨析,以期对同学们的学习有所帮助。 1).puzzled,puzzling puzzled指人或人的表情“迷惑不解的”;puzzling表示“令人迷惑的(事物)”。两者均可作表语或定语。例如: They're puzzled at my interest in such matters.他们对我在这样问题上的兴趣感到迷惑不解。 This is a puzzling answer.这是一个令人费解的答案。 2).be used to do,be used to doing,used to do be used to do sth.是动词use的被动结构,后跟动词不定式,不跟动名词,意思是“被用来……”;be used to doing sth.是习语,意思是“习惯于做某事”,后接名词或动名词,不接动词不定式;used to do sth.是习语,意思是“过去经常做某事”,后接动词不定式。例如: Wood can be used to make paper.木头可以(被)用来造纸。 They are quite used to flying in all sorts of weather.他们对于在各种天气飞行已经很习惯了。 He used to swim in the river.他过去经常在河里游泳。 3).the other,other,another other无范围,泛指“其他的;另外的”,常与no,any,many或some等连用;the other特指两方中的“另一方”,或两部分中的“另一部分”,如果other前有名词所有格或物主代词,则不用the;another泛指“其他的,另外的”,常用于三者或三者以上的情况,后接单数名词或“数词+复数名词”。例如: Mary is here,but the other girls are still out in the playground.玛丽在这里,但是其他女孩还在运动畅 I have no other choice.我没有选择的余地。 I have many other things to do.我另外还有很多事情要做。 Give me another chance,please.请再给我一次机会。 4).be content to do,be content with be content to do指“满足于(做某事)”,后接动词不定式,不接名词或动名词;be content with指“(对……)感到满足”,后接名词、代词或从句。例如: He is content to eat simple food.他乐于吃一些简单的食物。 She was quite content with her life.她对生活感到相当满意。 He isn't content with his present achievement.他不满足于目前的成就。 高二册13单元易混词语练一练 本期“单元过关”讲解了本单元出现的几组同义词(组),你是否掌握了?可以在这里大显身手。选择最佳答案:1.The reason for his absence remains _________.
