一. 句型 1. It’s time for sth . 或 It’s time ( for sb . ) to do sth . 意为:该是……的时候了。例如: It’s time for dinner . 该是吃晚餐的时候了。 It’s time for children to go to bed . 是小孩睡觉的时候了。 2. It’s ( high ) time ( that ) sb . did sth . 意为:该是……的时候了。该句型中的that 从句需要用虚拟语气,谓语动词常用过去式。例如:It’s high time that we stated . 我们该出发了。 It’s time that we devoted ourselves to our country . 该是我们报效祖国的时候啦。 3. This is the time when sb . should do sth . 或The time has come when sb . should do sth . 这两个句型也用来表示“该是……的时候了”,when 引导的定语从句用陈述语气或“should + 动词原形”的形式。例如:This is the time when you should get up .是你该起床的时候了。 The time has come when we must part from each other .该是我们必须道别的时候了。 提示:以上几个句型都可以表示“该是……的时候了”,形式虽然不同,却可以互相换用。如“该上学了”,可用下面几种句型来表达: It’s time for school . It’s time for us to go to school . It’s ( high ) time that we went to school . This is the time when we should go to school . The time has come when we should go to school . 4. every ( each , any , next , first , last ) time 作连词使用,引导时间状语从句。例如: Every ( Each ) time I saw him , I found him to be taller . 我每次遇见他,都觉得他又长高了。 The last ( first ) time I went to China , I visited Shanghai . 我上(第一)次到中国时,游览了上海。 5. by the time 引导时间状语从句时,意为:到……时为止,主句一定要用完成时态。例如: By the time he was twelve , Edison had built a chemistry lab for himself 。 爱迪生十二岁时,就建立了自己的化学实验室。 6. This is the first ( second , last ) time ( that ) sb . has done sth . 意为:是某人第几次……。在该句型中,this 可以由that 或it 替换;从句中的谓语动词必须用完成式,且要与主句谓语动词be 的时态保持一致。 例如: This is the third time I have been to Beijing . 这是我第三次去北京了。 That wasn’t the first time Linda had taken too many pills . 那不是琳达第一次服用这么多的药丸了。 It will be the fifth time that he will have been invited to such a meeting . 这将是他第五次应邀参加这种会议。 7. 三倍以上倍数的表达方式常用以下几种句型: (1)A is times + as + 形容词或副词的原级 + as + B (2)A is times + 形容词或副词的比较级 + than + B . 例如:The sitting room is 3 times as large as the kitchen . 起居室的面积是厨房的三倍。 Your bag is three times larger than mine . 你的包比我的大三倍。 Your cake is twice the size of mine . 你的蛋糕比我的大一倍。 < 1 > 提示:以上三个句型可互相换用,但有两点需注意:在使用句型(2)时,要注意“倍数”的表达法,使用句型(3)时应首先掌握length , width , depth , height , weight , size 等几个由形容词变化过来的名词形式。例如: The boy is three times as heavy as his little brother . The boy is twice heavier than his little brother . The boy is three times the weight of his little brother . 二. 词组 1. in no time 立刻;马上 at no time 决不;在什么时候也不(当at no time位于句首时,该句须用倒装语序)例如: They arrived in no time . 他们立刻赶到了。 At no time should we give in . 在任何时候我们都不要屈服。 2. at a time 一次;同时 at one time 从前;曾有一时(常与过去式连用)例如: We can’t do two things well at a time . 我们不能同时做好两件事情。 At one time there were not so many cars on the streets . 从前这条街上没有这么多车。 3. ( at ) any time 随时(at可省略)any time 哪里,哪里;随时效劳(是用来回答别人道谢的话)例如:You may use my dictionary ( at ) any time . 你随时可以使用我的字典。 —Thanks for helping me out of trouble . 多谢您的帮助,我摆脱了困境。 —Any time . 随时为你效劳。 4. at all times 经常;老是(= always ).at times 有时;偶尔(= sometimes )例如: He comes late to school at all times . 他老是上学迟到。 At times I go out to the beach . 有时候我到海滩去。 5. some time 一段时间;一些时候 sometime 将来某个时候 sometimes 偶尔;有时 some times 若干次 例如: I have been waiting for your for some time . 我等你老长时间了。 I’ll visit you sometime next year . 明年有机会我会去拜访你的。 He comes to see me sometimes . 他有时来看我。 He has been here some times . 他来过这儿多次了。 三.动词用法 time除了能作名词,表示“时间、时刻、次数、倍数”外,还能作及物动词使用,表示“安排好时间、为(比赛或选手)计时”。例如: He timed his journey so that he could arrive at the hotel before dark . 他安排好了他的旅程,以便能在天黑以前到达旅馆。 How long can you hold your breath underwater ? Take a deep breath and I’ll time you . 你在水下能潜多久呢?深呼吸一下,我给你计时。 相关链接:教学论文
