Unit 1 Can you play the guitar?

Unit 1 Section B教材全解

1.Hello,I’m Peter.I like to play basketball.I can speak English and I can also play soccer.你好!我是彼特。我喜欢打篮球。我会说英语,也会踢足球。

【重点注释】①I like to play basketball.我喜欢打篮球。like doing sth.和like to do sth.都表示“喜欢做某事”,但动名词所表示的动作,在意义上比较一般和抽象,时间观念不强,不指某一次动作;动词不定式则常指某个具体的一次性的动作。例如:She likes swimming.她喜欢游泳(经常性的爱好)。She likes to swim this afternoon.她今天下午想游泳(特指某一次的动作)。另外,在搭配(使用方法)上,还有一点区别:(1)“like to do sth.”一般与“would”搭配,构成would like(would like 后面只能跟动词不定式,即woule like to do sth.),表示“意愿”。例如:I would like to swim with you .我愿意和你去游泳。Would you like to skate? 你愿意去滑冰吗?Would you like to have some bananas?你想吃些香蕉吗?(2)“like doing sth.”表示“爱好”。例如:I like watching TV.我喜欢看电视。Do you like singing ?你喜欢唱歌吗?

②I can speak English and I can also play soccer.我会说英语,也会踢足球。这是一

个并列句,由连词and连接两个简单句。and可以连接语法作用相同的词、短

语或句子,表示并列或对称的关系,可翻译为“和;并(且);又;兼”等。例如:Mille and Amy go to the park every week.米莉和艾米每周都去公园。They love playing football and we love playing football too.他们喜欢踢足球,我们也喜欢踢足球。

【比较记忆】Unit 1 Section A课文全析5:Lisa wants to join the chess club,but she can’t play chess.莉萨想加入国际象棋俱乐部,但她不会下国际象棋。but,连词,表示转折关系,意为“但是”。而and是表示并列、递进关系的连词,意为“并且”。例如:She can dance,but she can’t sing.她会跳舞,但她不会唱歌。I can play the piano,and I play it very well.我会弹钢琴,并且弹得很好。

③副词also意思是“也”。例如:I’m 19 years old.John is also 19 years old.我19岁,约翰也19岁。

【比较记忆】also与too的意思都是“也”,它们的区别如下:

also用于肯定句,通常位于be动词、助动词或情态动词之后,行为动词之前。

too用于肯定句,通常放在句末。

例句:He is good at English.He is also good at Japanese.他擅长英语,也擅长日语。She can also speak English.她也会说英语。I also want some tea.我也要点茶。I know the answer,too.我也知道答案。

注意:too修饰形容词或副词,作程度状语时,表示“太,过分”之意。例如:He speaks too fast.他说话太快。The boy is too young.这个男孩太小了。

2.Hi,I’m Ma Huan.I can play ping-pong and chess.I like to talk and play games

with people.嗨,我是马欢。我会乒乓球和国际象棋。我喜欢与人交谈和玩游戏。

【重点注释】①I can play ping-pong and chess.= I can play ping-pong and I can play chess.我会打乒乓球,也会下国际象棋。I like to talk and play games with people.= I like to talk to people and I like to play games with people.我喜欢和人交谈,也喜欢和人玩游戏。

②play games做(玩)游戏。play games with sb.和某人一起做游戏。

③people泛指“人们”,是集体名词,作主语时谓语动词用复数形式。例如:Some people speak French in this country.在这个国家,一部分人讲法语。

【拓展记忆】1)the people意为“人民”。例如:We study hard for the people.我们为人民努力学习。2)people还可表示“民族;种族”,是可数名词,其复数

形式为peoples。例如:There are fifty-six peoples in China.中国有56个民族。

3.Are you busy after school?No?Can you speak English?Yes?Then we need you

to help with sports for English-speaking students.It’s relaxing and easy!放学后

你忙吗?不忙?你会说英语吗?是的?那么,我们需要你帮助说英语的学生进

行体育运动。它轻松且容易!

【重点注释】①busy形容词,意为“忙的,繁忙的”,反义词是free,意为“空闲的,有空的”。be busy=have no time=be not free很忙.形容词常和be连用,作表语。如短文下一句:It’s relaxing and easy!它轻松且容易!

【试题链接】根据句子中所给单词的首字母或中文提示,填写正确的单词。

Ted is so b that he has no time to watch TV in the evenings.

(由句意“在晚上,泰德如此忙以至于他没有时间看电视。”知此处需填形容词busy。)

【拓展记忆】be busy with sth.忙于某事/be busy(in) doing sth.忙于做某事。例如:My uncle is busy with his work.我叔叔正忙着他的工作。I am busy doing my homework.我正忙着做我的家庭作业。be busy doing sth侧重于动作,sth.是名词或代词,do是动词的形式,doing是v.ing形式。be busy with sth.侧重于状态。be busy后跟名词或代词,用with;be busy后跟动词,用v.ing形式。两者意思都一样,可以互换。例如:He is busy doing his homework(他忙着做家庭作业).=He is busy with his homework(他忙于家庭作业). He’s busy with(playing) soccer.他忙于踢足球。They’re busy watching TV.他们忙着看电视。注意:不要出现用with,还用v.ing形式。We’re busy with cleaning the classroom.(×)

②Then we need you to help with sports for English-speaking students.那么,我们需

要你帮助说英语的学生开展体育活动。need作为实义动词,意为“需要”,此

时need有人称和数的变化,need后面的宾语可以是名词、动名词(v.ing)、动

词不定式或代词。need to do sth.意为“需要做某事”;need sb.to do sth.意为“需要某人做某事”;need后面接动名词(v.ing)时,动名词表被动意思,此时主

语常为物。The room needs cleaning.这个房间需要打扫。need既可用于肯定句,也可用于否定句和疑问句,构成否定句和疑问句时要借助于助动词do或does 等。例如:You need to talk with your mother.你需要和你妈妈谈谈。Does your
