重点句型解析
1. What time do you usually get up?1)这是一个用来询问什么时间做某事的常用句型,意思是“你几点起床?” 。它的句式是“What+time+助动词do/does+主语+谓语动词原形+其他?” 。当主语是三单时用does,其余人称用do 。它经常用来询问具体的点钟,相当于对划线部分(表示具体时间的状语)提问 。例如:I usually have lunch at 12:00. (对划线部分提问) 我通常在12点吃午饭 。What time do you usually have lunch? 你通常什么时间吃午饭? -What time does Rick eat breakfast? 里克什么时候吃早餐? -He eats breakfast at seven o’clock. 他七点吃早餐 。2)短语what time的意思是“几点”,它和when是同义词,都是对时间进行提问,但what time所问的时间范围比较小,一般用来提问比较精确的时间,回答的时候一般具体到几点 。而when所问的时间范围比what time要大,回答的时候可以用几点钟,也可以是上午或者下午,甚至是哪一天、哪一年 。例如:-What time/When do you usually get up? 你通常什么时间起床? -I usually get up at seven o’clock. 我通常七点起床 。-When is your birthday? 你的生日是什么时候? -It’s May 10. 是5月10日 。3)询问时间还可以用句型: What’s the time now? = What time is it by your watch? =What’s the time by your watch? (你的手表)现在几点了?回答别人询问几点可以用句型:“It+is+时间.” 。例如:It’s six. 现在六点了 。2. I usually get up at six thirty.这个句型主要用来回答“What time /When…”句型的提问 。在回答做某事的具体时间时,要注意英语时间的表达法 。英语时间的表达法主要有以下几种情况:1)如果时间在整点可以用“整点数字+o’clock”这种形式表达,有时候可以不用o’clock 。例如:It’s eight (o’clock) now. 现在八点了 。2)如果是几点几分,分钟不超过半个小时(包括半小时),可以直接用数字表示 。例如:6:11→ six eleven (6点11分) 也可以用介词past表示,past的前面是分钟,past的后面是钟点数,表示几点过了几分的意思 。例如;6:11→ eleven past six (6点11分) 如果是15分钟可以用a quarter 。例如:7:15 →a quarter past seven (七点一刻) 如果是30分钟可以用half 。例如:6:30 →half past six (六点半)3)如果是几点几分,分钟超过半小时,可以用介词to,to的前面是分钟(是差几分到下一点的分钟数字),to的后面是下一个点的数字 。例如:6:58 →two to seven (7点差2分) 6:45→ a quarter to seven (七点差一刻)3. either…or1)“either…or” 意为“要么……要么;或者……或者……;不是……就是……”,用来连接两个并列的词、短语或者句子 。例如:You can either have tea or coffee. 你喝茶也行,喝咖啡也行 。You must either go at once or wait till tomorrow. 你要么马上走,要么等到明天 。2)“either…or…”连接的两个并列成分作主语时,谓语动词通常与其靠近的主语保持一致,简称为就近一致 。例如:Either he or you are right. 要么他对,要么你对 。Either you or he is right. 要么你对,要么他对 。4. be good forbe good for意为“对……有好处,对……有益处”,介词for后接名词或代词 。其反义词为be bad for,意为“对……有害处” 。例如:Junk food is not good for our health. 垃圾食品对我们的健康没有好处 。Smoking is bad for you. 吸烟对你有害 。拓展:其他常见的good 的相关词组还有:1)be good at 擅长…… 例如:She is good at English. 她擅长英语 。2)be good with 善于……;精明的;与……相处的好 He is very good with the children. 他与这些孩子处得很好 。3)be good to 对……友好 My friend was good to me when I was ill. 我生病时我的朋友对我关怀备至 。5. That’s a funny time for breakfast!“…time for sth. /…time to do sth. ”,表示“做……的时间” 。例如:We have no time for exercise. 我们没有时间锻炼 。She has enough time for breakfast. 她有足够的时间吃早餐 。He has little time to sleep. 他几乎没有时间睡觉 。拓展:由time 构成的常见的句式还有 “It’s time for… / It’s time to do… ”意为“该做……的时候了” 。例如:It’s time for lunch. 该吃午饭了 。It’s time to go to bed. 该睡觉了 。“It’s time for sb. to do sth.…”意为“某人该做某事了” 。例如:It’s time for us to go home now. 我们该回家了 。
