2022-2023学年人教版英语七年级下Unit2暑假复习知识点详解与训练一、知识点详解 Section A 1. —What time do you usually get up? —I usually get up at six thirty. —They usually eat dinner at a quarter to seven in the evening.—He usually gets up at half past six in the morning.1).what time与when都可用于询问时间。但what time所问的时间范围较小， 一般询问比较精确的时间；而when(什么时候) 所问的时间范围比what time要大，可询问小的时间点， 也可询问日期。例：What time / When do you usually have breakfast? 你通常几点/什么时候吃早饭？例：When is Teachers’ Day?  教师节是什么时候？2).询问时间在英语中，常用What’s the time?或What time is it?来询问时间，有时也可用Do you know the time?等句式来问时间。回答方式均用It’s...例：—What time is it?几点了？—It’s seven o’clock.七点。3).时间表达法：(1)整点表达法：如果时间是“整点”，应说：......点钟＋o’clock (o’clock可以省略)。例：It’s seven (o’clock) a.m. now. 现在是上午七点。例：It’s two o’clock p.m. 午后两点。(2) “几点几分”有两种表达法：①顺读法：按“钟点数＋分钟数”的顺序，这种方法居多，也较简单。例：6:18  six eighteen例：7:30  seven thirty②逆读法：按“分钟数＋past／to＋钟点数”的顺序表达。A. 分钟数不超过30(包含30)时，用“分钟数＋past＋钟点数”表达。例：6:05   five past six例：8:10   ten past eightB. 分钟数超过30时，用“分钟数＋to＋钟点数”表达。其中“分钟数”为60减去原分钟数，“钟点数”为下一个钟点数，表示“差几分几点”。例：9:50     ten to ten例：2:58     two to three(3)特别注意：①分钟数是15时(一刻钟)，一般不说fifteen，而说a quarter；②分钟数是30时(半小时)，一般用逆读法“half past +钟点数”。例：10:15   a quarter past ten例：7:30    half past seven 2.brush teeth 刷牙1).brush既可以作动词，又可以作名词。作动词时，意为“刷；擦”；作名词时，意为“刷子；画笔”。例：How do you brush your teeth? 你是怎么刷牙的？例：I can draw a picture with a brush. 我可以用刷子画画。2).teeth是名词，意为“牙齿”，它是tooth的复数形式。例：She has very nice teeth. 她有一口漂亮的牙齿。 3.get dressed 穿衣服1).dressed是形容词，意为“穿着衣服”。dress作动词时，意思是“给……穿衣；穿着；打扮”。常用于“be dressed in + 表示颜色的形容词”，表示“穿某颜色的衣服”。如：例：My sister is only two years old. Mother often dresses her. 我的妹妹只有两岁。妈妈经常给她穿衣。例：She is dressed in black today. 今天她穿一身黑。2).dress还可以作名词，意为“连衣裙”。例：She likes red dresses. 她喜欢红色连衣裙。 4.Scott has an interesting job.job与work 辨析job是可数名词，主要指有报酬的工作。work是不可数名词，主要指要付出努力 的劳动。例：Bob wants to find a good job.鲍勃想找一份好的工作。例：I have much work to do today. 今天我有很多工作要做。 5.That’s a funny time for breakfast!time常常和介词“for”搭配，表示“做……的时间”。如：例：We don’t have too much time for sports. 我们没有太多的时间开展体育活动。例：Time for dinner, children.
