1. What do you usually do on weekends?周末你通常做什么? (1) usually作副词,表示“通常地”,其位置比较灵活,可位于句首、句中(在系动词、情态动词、助动词之后,在实义动词之前)或句尾。但在否定句中常位于句中。如:

She usually have lunch at school.她通常在学校吃中饭。

Usually I play basketball with my classmates after school.我通常放学后和同学们一起打篮球。

He doesn’t usually watch TV.他并不通常看电视。

【链接】always总是,一直;usually通常;often经常;sometimes有时;hardly ever几乎不;never从不;它们都是频度副词,表示的频率由always向never递减。 (2) on weekends意为“在周末”。其中“on+时间名词(具体的某日)”表示某一特定时间。如:

on Sundays在星期日 on September 1sth 在九月一日 【辨析】常用于时间之前的介词in, on, at的用法。 ① in表示一段时间,常用于年、月、季节。如: in 2007在2007年 in March在三月 in summer在夏天

② on表示地某一天,常用于星期、日期或某天的上午、下午、晚上。如: on Saturday在星期六 on the morning of October 10th在十月十日的上午

3. Twice a week.一周一次。

(1) twice是一个频度副词,表示“两次”。英语中表示次数的除“一次”为once,“两次”为twice之外,其他都用“基数词+times”来表示。如:three times三次 (2) 要表示某一动作在某一段时间内发生的频率,则用“次数+一段时间”,也是对how often引导的特殊疑问句的回答。如:

—How often does your brother come home?你兄弟多长时间回家一次? —Three times a year.一年三次。

4. He sometimes watches TV.他有时看电视。

(1) sometimes有时,表示动作的不经常性,多用于现在或过去时态。如: She sometimes helps her mother clean the house.她有时帮妈妈打扫房子。

【辨析】sometime, some times, some time ①sometime副词,意为“某时”,表示在过去或将来的某个时候,指的是时间点,用于过去时或将来时,对它提问用when。如:

I will buy a computer sometimes next week.我要在下周的某个时候买台电脑。

My father came back from New York sometime last month.我父亲上月某个时候回来了。 ②some times意为“几次(倍)”,time是可数名词。如:

The teacher asked her to copy the word some times.老师叫她把那个单词抄写几遍。 ③ some time用作名词短语,指“一段时间”。如: I waited for you for some time.我等你一些时候了。 【拓展】表示“有时”的短语有:at times

(2) watch用作及物动词,意为“观看,注视,监视”,指非常仔细地,有目的地看,常与电视、比赛等搭配。如:

I watched the children playing games.我观看孩子们在做游戏。

They are going to watch the football game this evening.今晚他们要去看那场足球赛。 【辨析】look, see, watch

①look是不及物动词,后接宾语时要用介词at,指看的过程,强调有意识的动作。如: Look! It’s going to rain.看!天要下雨啦。 Please look at the blackboard. 请看黑板。

②see既可作及物动词,又可作不及物动词,强调看的结果,即“看见,看到”,但不一定是有意识的。如:

Let me see!让我想想!

Can you see the birds in the tree?你看见树上的鸟儿吗?

另外,see也用于一些短语中。如:see a doctor看医生, see a movie看电影 5. Most students exercise three or four times a week.大部分学生一周锻炼三、四次。 (1) most作形容词,意为“多数的,大部分的”,用于修饰名词。如: Most schools have computers.大部分学校有电脑。

(2) exercise在本句中作动词,意为“运动,锻炼”。如:

2

【链接】exercise可作名词,表示“体育锻炼,运动”时,是不可数名词;表示“练习,体操”时,是可数名词。如: Swimming is good exercise.游泳是很好的运动。 We do morning exercises every day.每天我们做早操。

6. As for homework, most students do homework every day.至于家庭作业,大部分学生每天得做。

as for意为“至于??,关于??”,用于说话时提及的另一个人或事,或事物的另一个方面。其后可跟名词、代词或动名词作宾语。如: As for the report, I think it was written by Li Hong.至于那份报告,我认为是李洪所写。

【拓展】as的相关短语:

as if / as though好像 as well也;又as well as既??又;与??一样

7. Here are the results of the student activity survey at Green High School.下面是格林高中学生活动调查的结果。

The results for “watch TV” are interesting.“看电视”的调查结果很有趣。

(1) 这两句中的the results of…和the results for…的意思相近,都表示“??的结果”。 (2) interesting作形容词,表示“有趣的,引起人兴趣的”,可作表语,也可作定语,用来修饰“物”。如:

The story is very interesting. 那则故事非常有趣。 This is an interesting movie. 这是一部有趣的电影。 8. hardly ever几乎不

Hardly ever与hardly意思相同,都是表示频度的副词,其意义是否定的,常用来修饰表示能力的词,表示事实上不可能。如:

He hardly (ever) plays the computer games on school days.他在上学的日子里几乎不玩电脑游戏。
