如：It’sten o’clock a. m. 现在是上午十点整。

（2）非整点时间可直接采取读数法。

如：It’s eight-thirty. 是八点三十分。

注意时间的表达方式：用数词。

点与分钟之间用连字如：eleven-thirty 11点30分nine-twenty-five 9点25分6:10 →six-ten 8:50→eight-fifty 9:30→nine-thirty10:15→ten-fifteen 7:45→seven forty-five 11:05→eleven-five（3）非整点时间的分钟数不超过30分钟，也可用介词“past”。

如：6:10→ten past six 11:05→five past eleven 10:15→a quarter past ten或fifteen past ten 8:15→a quarter past eight或fifteen past eight 9:30→half past nine或thirty past nine（4）非整点时间的分钟数超过30分钟，用介词to。

如：11:50→ten to twelve 7:31→twenty-nine to eight9:45→a quarter to ten或fifteen to ten 12:59→one to thirteen此句话还有几种表达方式。

如：What is the time? 几点了？What time is it by your watch? 你的手表显示几点了？A: What’s the time, please? B: It’s twelve o’clock.2. what time与whenwhat time翻译为“几点”问的是具体的时间，一般回答要具体到小时。

What time do you go to school? 你什么时候/几点上学？I go to school at half past seven o’clock. 我七点半去上学。

回答具体到点钟，且注意在几点前边的介词用at。

when也是对时间的提问，但与what time的区别是：用when提问，回答既可以是具体的时间，也可以是不具体的时间，如：in the morning，last year，in 1998等范围大的时间，例如：When does he take a shower？他什么时候洗澡？He takes a shower in the morning. 他在早上洗澡。

也可用具体时间：I take a shower at 6 o’clock in the morning. 我早上六点洗澡。

3. 关于一般现在时。

（语法重点）（1）一般现在时态的意义是：①表示现在的特征或状态。

如：He is at home today. 他今天在家。

②表示经常性、习惯性的动作。

常和频率副词always, often, usually及every day等表示时间的短语连用。

如：I go to school at 7:00 every day. 我每天7点钟去上学。

③表示主语具备的性格或能力。

如：She likes pears very much. 她非常喜欢梨子。

They speak English. 他们讲英语。

（2）肯定陈述句：当主语是第一、二和第三人称复数时，谓语动词用原形。

当主语是第三人称单数时，谓语动词用第三人称单数形式。

例如：①They stay at home on Sundays. 他们星期天呆在家。

②He does his homework in the evening. 他在晚上做作业。

（3）否定句：当主语是第一、二及第三人称复数时，否定句借助助动词do＋not，当主语是第三人称单数时，否定句借用does＋not，并将动词第三人称单数还原。

例如：①They don’t stay at home on Sundays. 他们星期天不呆在家里。

②Hedoesn’t do his homework in the evening. 他晚上不做作业。

（4）疑问句：当主语是第一、第二及第三人称复数时，疑问句在句首加Do。

当主语是第三人称单数时，疑问句在句首加Does，并把谓语第三人称单数还原。

例如：①Do they stay at home on Sundays? 他们星期天呆在家吗？②Does he do his homework in the evening? 他晚上做作业吗？△以speak为例归纳动词do的各种句式：肯定式否定式I speak English. I do not (don’t) speak English.You speak English.
