这是个固定短语,常用于表示劝说、激励、鼓励等,较口语化。如:
Come on! We're waiting for you. 快来吧!我们在等你。
Run with it like this. Come on! 就这样带着跑,要快呀!
come on这个短语在不同的场合有不同的意思,如:
Come on! Don't be shy! 来吧!别害羞!(劝人发言或表演)
Come on! Don't worry. Everything will be all right.得啦,别担心了!一切会好起来的。(劝说)
Come on! This way, please! 请走这边!(招呼)。
Come on! Don't keep us waiting! 快!别让我们老等你!(不耐烦的催促)
"Come on!" they shout! "加油,快,快跑!!他们大声喊着。
(用于体育比赛时,有加油助威之意)
2. Are you OK? 你没事吧?
OK在这儿可用all right代替,有"没事的""好的""正常的"之意;OK还可以表示赞同对方或征询对方的意见,意思是"行""好""可以",如:
-Let's go to school. OK? 我们上学去,好吗?
-OK. 好的。
-Is Jim OK now? 吉姆现在好吗?
-Yes, he is OK. 是的,他很好。
3. I am not good at basketball. 我不擅长篮球。
be good at…指某人擅长于(做)某事,at在这里是一个介词,可以在其后跟名词,be good at sth.指擅长于某事;或在其后跟动词-ing形式,表示做某事做得很好,很出色,其同义短语是do well in。
要注意at和in的固定搭配。
She is good at English. 她英语学得好。
He does well in Chinese. 他语文学得好。
4. Do you want a go? 你想试一试吗?
want a go = want to have a go,还可说"have a try"试一下,其中go是名词,作"试一试""尝试"讲。如:
Let me have a go. 让我试一试。
Would you like to have a go at riding a bike? 你想不想试骑下车?
5. Throw it like this. 像这样扔。
句中的like是介词,表示"像……一样"。后面一般接名词或代词。like引导的介词短语在句中可以作状语、定语或表语。
Li Mei looks like her mother.李梅看上去像她妈。
Lucy has a hat like a cat. Lucy有顶像猫的帽子。
6. Don't throw it like that. 别像那样扔。
这是句祈使句。祈使句表示命令或请求,通常省略主语you。祈使句有肯定和否定两种形式。肯定句结构为:动词原形+其它成分!,否定句结构为:Don't +动词原形+其它成分! 如:
Come this way, pleas. 请到这边来。
Please don't worry! 请别着急!
Let's go. 我们一起走吧。
7. Ling Feng, David and some other boys are playing basketball. 凌锋、戴维和一些其他男孩在打篮球。
are playing basketball. 正在打篮球。这是一种新的时态"现在进行时"。它的构成是由"助动词be+动词的ing形式(叫做现在分词)",表示"现在正在做某事"。助动词be的变化词"是"动词be一样。如:
I am speaking. 我在讲话。
You are listening. 你们在听。
The little girl is singing. 那个小女孩在唱歌。
●语法
1.运用can
can有can和could(过去式)两种形式。can的后面直接跟动词原形。用于一切人称和单、复数。由情态动词can引起的一般疑问句可用来表示向对方提出请求,也可以表示做某事的能力。
(1)表示客观条件的许可,可译成"可以"。
The school is over. You can go home now. 放学了,你们可以回家了。
"Can I borrow your bike?" "Yes, you can. /No, you can't."
"我可以借你的自行车吗?""行/不行。"
(2)表示能力:"会","能"
He can skate. 他会滑冰。
"Can you play cards?" "Yes, I can./No, I can't.""你会打牌吗?""会。/不会。"
(3)与not搭配,构成can的否定式can not或can't,表示"不可能"或"不会有的情况"。注意字母a在can't中发音的变化。
"Can you sing this song in English?" "Sorry, I can't."
"你能用英语唱这首歌吗?""对不起,我不会唱"
She can't be only thirteen. 她不可能只有十三岁。
(4)could是can的过去式;但当could用于现在时和将来时中,代替can时,表示语气更为客气或婉转。
Could you help me, please? 你能帮我一下吗?
Could you give me a glass of coke, please? 你能给我一杯可乐吗?
2.祈使句 Imperatives
祈使句主要来表示命令、叮嘱、号召等,谓语动词用原形。否定形式是在谓语动词前面加don't。祈使句一般没有主语,但实际上是对"You(你,你们)" 而言。标点符号一般用感叹号或句号,根据说话的语气而定。祈使句,一般都用降调。如:
Catch the ball! 抓住球。
Put them away, please. 请把他们收好。
Don't throw it like that. 不要象那样扔。
Please don't worry. 请别着急。
Now Let's play a guessing game. 现在让我们做个猜谜游戏。
Let him do it. 让他去做那件事吧。
如上所述Let's引起的句子也是一种祈使句,表示建议,这种句子的否定式是在Let's后加not构成;但如果是否定以Let引导的祈使句,则在Let前用don't. 如:
Let's not do it. It's hard. 这件事我们还是不做为好,太难了。
Don't let the boy carry this box. 别让那个男孩搬这个箱子。
