1. Which verb is used as the past f must?2. Which verb indicates an ability t d smething?3. Which verb makes a predictin abut the future?5. Which verb is used t give advice?6. Which verb indicates the permissin t d smething?
can和culd1. 二者都可表示能力,此时culd是can的 过去式。 e.g. Even a small persnal cmputer can stre great amunts f infrmatin. I culdn’t get tickets; they were sld ut.
2. 表示许可时,culd比can语气更委婉。 e.g. Yu can have my seat. I’m ging nw. Culd I have a drink f water, please?3. 表示猜测时, culd不是can的过去式, 它表示推测的可能性比can小。 e.g. Can he still be alive after all this time? If yu’re nt careful, yu culd get int even wrse truble.
may和might1. 表示允许或征询对方许可,might表示更加委婉的语气。(有时可与can/culd互换)e.g. —May I watch TV after supper? —Yes, yu may./N, yu mustn’t.否定回答时,用can’t或mustn’t,不用culdn’t。
2. 表示可能性,might可能性更小。e.g. They might be having a meeting, but I'm nt sure. 他们有可能在开会,不过我不确定。3. may放在句首可以表示祝愿。 e.g. Gd bless yu! 愿上帝保佑你!
must与have t1. 二者均表示“必须”,但must是指说话人的 主观看法,而have t则强调客观需要。must 用于一般现在时, have t有更多的时态形式。e.g. I have t wait here because I have n umbrella with me. 我不得不在这儿等,因为我没带伞。(强调客观需要) I must recite the text this mrning. 今天早上我必须背会这篇课文。(强调主观意志)
2. must用于一般疑问句时,否定回答常用needn’t或dn’t have t。 e.g. —Must I finish it tday? —N, yu needn’t.
3. must 常表示有根据的、比较确定的推测(只用 于肯定的陈述句),译为“一定,必定”。e.g. Yur mther must be waiting fr yu nw. 你的母亲现在一定在等着你。
shall和shuld1. shall用于第一、三人称的疑问句,用来表示 征询对方意见或请求指示。e.g. Shall I pen the windw? 你要我打开窗子吗? Manager, smene is waiting fr yu. Shall he cme in? 经理,有人在等你,他可以进来吗?
2. shall用于第二、三人称的陈述句,表示说话 者的允诺、告诫、威胁、命令、规定、必然性 等。e.g. Yu shall get what yu want if yu behave well. 如果你表现好的话,你就会得到你想要的东西。(表示允诺) He shall be srry fr it ne day, I tell yu. 有一天他会后悔的,我告诉你。(表示警告)
3. shuld表示义务或责任、建议或劝告、推断等。e.g. We shuld take gd care f ur children. Yu shuld give up smking and drinking. With an early start the yung men shuld be here by 10:00 am.
[点津] shuld有时可用于某些从句中,表示说话人惊奇、失望等感情色彩,常译为“竟然,怎么会”。e.g. I find it astnishing that he shuld be s rude t yu. 他竟然对你这样无理,真让我吃惊。
will和wuld1. 表示请求、建议,wuld比will更委婉客气。e.g. Wuld/ Will yu pass me the ball, please? 你可以把球传给我吗?
2. 表示意志、愿望和决心,wuld用于过去的情况。e.g. I will help yu if yu meet with truble. 如果你有麻烦,我乐意帮你。 She said that she wuld try her best t help us. 她说她愿意尽自己最大努力来帮我们。
3. wuld表示过去的习惯性动作;而used t表示过去常常做某事,强调现在不是这样了。e.g. Each time his mther’s birthday came, he wuld buy her a present. 每次到他母亲生日的时候,他都要给她买一件礼物。(表示过去的习惯) My father used t g t the ffice by bike when he was yung. 我父亲年轻的时候总是骑车去上班。(现在不是这样了)
