(1)while、when、as的用法区别：while常表示一个较长的动作,它引导的从句动作与主句的动作是只能是同时发生的、是平行的;when可以表示较短的动作也可以表示较长的动作,主句和从句的动作可以同时发生也可以先后发生;as与上两词同义,可替换while和when, 表示主句和从句的动作同时发生,常译为“一边……一边……”。如：Please do not trouble me while I am writing my homework.(我写作业时请不要打扰我)/ I’ll go home when I have finished my job.(我干完了活儿就回去)(不是同时发生)/ They were running quickly across the road when they heard the sound of a truck coming.(他们正地穿过马路忽然听到了卡车开来的声音)/ As we walked in the dark street, we sang songs and talked loudly.(当我们在黑洞洞的街上走路时我们高声地唱歌说话)

(2)till/until与not…till/until的区别：前者表示一个延续性的动作,后者表示一个才开始的动作。如：I will stay here and watch the baby until you return.(我会呆在这里看着娃娃直到你回来)(stay这个动作一直进行到你return) / They won’t go on working until they get what they think is reasonable.(他们要到获得了他们认为合理的东西时才会继续干下去的)

另外till与until基本可以互换,但是在句首时只能用until,不能用till. 如：Until the last minute of the match we kept playing.(我们坚持到比赛的较后一分钟)/ Not until he had finished his work did he go home.(直到做完工作他才回家)(倒装句)

(3)though与although的区别：两个词都表示“虽然”,均不可以与but同时使用,但在句中可加still或yet连用。although“尽管、虽然”仅作连词,比较正式,一般可以换为though; though“虽然、尽管、即使”,①还可以与even连用(=even if),表示“即使、纵然”,②作副词时意思是“然而、不过”,不能放在句首。③although不能放在句末，though则可以，用“，”隔开。如：He passed the exams although illness prevented him from going to classes.(尽管疾病使他无法上课但是他还是通过了考试)/ she won’t leave the TV set,even though her husband is waiting for her for the supper.(她不愿离开电视机虽然丈夫在等她吃饭)/ It was a quiet party. I had a good time, though.(这是个不热闹的聚会尽管如此我还是玩得很开心)

(4)prefer to…rather than…与prefer…to…的区别：prefer to…rather than…后面都是用动词原形,prefer…to…都是用动名词或名词。如：I prefer English to Japanese.(与日语相比我更喜欢英语)/ I prefer to learn English rather than learn Japanese. (与日语相比我更喜欢学英语)

（5)如果“have”作“有”讲,也可以在它后面加not构成否定式,其形式与have got的否定式相同。 如：I haven’t (got) any brothers or sisters.(我没有兄弟姐妹)

have 的否定形式：

当表示“有”的意思时，可以采用以下三种形式：have+not;do not+ have; have+ no+ n. 如：I have not enough food to eat.= I do not have enough food to eat. =I have no enough food to eat.

当have为助动词时，用“have+ not”结构。如：I have not been toShanghai。

当have既不表示“有”，也不作助动词用时，用“do not+ have”结构。I didn’t have breakfast this morning.

具体到反义疑问句中，则遵循以下原则：

a.当have表示“有”含义时，反意疑部问部分可以用have形式，也可以用do形式。例如： He has a book in his hand, hasn't he? He has a book in his hand, doesn't he? b.当陈述部分的动词是have“有”的否定形式时，反意疑问部分是用have形式还是用do形式，取决于陈述部分的动词形式。例如： You haven't a car, have you? You don't have any money with you, do you? c.当have不表示“有”含义而表示其他含义时，反意疑问句则必须用do的形式。例如： We had a good time in the vacation, didn't we? He has his breakfast at seven everyday, doesn't he? You have to get up early tomorrow, don't you?

(6)fall 、drop的区别：fall指东西由高处向下坠落,不及物动词;也可以作连系动词,意思是“变得,进入某种状态”。drop表示物体由高处往低处落下,不及物动词;或让物体落向低处,及物动词。如：The man fell off the tractor and hurt himself. (那个人从拖拉机上摔下来跌伤了)/ Soon after they touched the pillows they fell (系动词) fast asleep. (他们头挨枕头不久就睡着了)/ He felt as if he had to drop maths.(他觉得似乎要放弃数学)/ He dropped a letter into the mail-box.(他向邮箱里丢了一封信)

(7)join、join in、take part in的区别：join多指参加组织、团体、党派等,后面跟人时表示和某人一起参加某项活动;join in指参加某项游戏或活动;take part in多指参加群众性的活动、运动、会议等。如：He joined the army in 2001.(他2001年参军)/ They joined me in congratulating you.(他们和我一起向你祝贺)/ Do join us in the game.(千万参加我们的比赛) / He took an active part in the students’ movement in the 1940s.(在二十世纪40年代他积极参加学生运动)

(8)beat、hit、strike的用法区别：beat指“连续不断地打击;(心脏的)跳动”;hit指“一次性地撞击、命中”;strike与hit基本同义,还可以理解为“划(火柴)、给……深刻的印象”。如：The man looks dead, but his heart is still beating weakly. (那个人看上去死了可心脏还在微弱地跳动) / He hit the ball so hard that it flew over their heads and fell into the lake. (他踢球的劲太大球飞过他们的头顶落入水中) / He went into the room and struck a match(火柴). (他走进房间划着了一根火柴)

(他警告路人小心窃贼) / I warn you that you will fail in the coming exams if you are still so lazy. (我警告你：如果你还这么懒在即将来到的考试中你会不及格的。) / He was warned not to go out in the late night. (他受到警告不要在深夜出去)
