Have a good time
例如:
(1)Did you know if / whether he would come tomorrow?
你曾知道他明天是否回来吗?
(2)Mother asked if / whether we needed some more tea.
妈妈问过我们是否再要一些茶。
在下面几种情况下不能用if代替whether:
(1)当 whether与 or not连成一个词组时。例如:
I can't say whether it is going to rain or not.我不知道明天是否下雨。
(2)whether用在不定式前面时。例如:
He can't decide whether to go.他不能决定是否去。
(3)whether引导的从句放在句首时。例如:
Whether this is true, I can't say.不管是不是真的,我说不准。
(4)whether用在介词后面时。例如:
She is worrying about whether she can finish the work on time.
她正担心,她是否能准时完成工作。
8.I'd like to book four tickets, please. 我想定四张票。
book在此是动词,意思是"预定;买票"。例如:
(1)You had to book early if you want to have dinner in that restaurant.
如果想去那个饭店吃饭,你得早点儿定座。
(2)Have you booked your passage to Shanghai? 你到上海去的舱位定好了吗?
(3)Could I book a ticket through to Hainan Island?
我能买一张直达海南岛的票吗?
9.That sounds really cool! 这听起来确实很酷!
sound是系动词后跟形容词作表语。类似用法的动词还有:get, turn, smell, taste, feel, look等。例如:
(1)It looks more beautiful in the sun. 在阳光下,它看起来更漂亮。
(2)The dish smells delicious.菜闻起来很香。
(3)I often feel tired.我常感到疲倦。
(4)It tastes better than it looks.它看起来不怎么样,味道还不错。
(5)Her name sounds beautiful.她的名字听起来很好听。
疑问词引导的宾语从句
在宾语从句这一个语法项目中,疑问词引导的宾语从句是比较难于理解的。本单元教学由连接代词和连接副词引导的宾语从句。所谓连接代词和副词,实际上就是我们以前学过的疑问代词和副词,如who, whose, whom, what, which, when, where, why, how以及由how构成的词组。但必须注意两点,一是它们在构成疑问句时叫疑问词,引导宾语从句时称作引导词。一是它们和that不一样,在从句中有含义,担任相关的句子成分,所以不能省略,另外,它们须放在宾语从句之首,宾语从句必须是陈述句结构。学习宾语从句,主要应当注意以下三个方面的内容:引导词,从句语序以及主从句的时态的一致性。现在以连接词的三种不同情况来进行宾语从句的总结。
1 连接代词引导的宾语从句。
Can you tell me who will give us a talk?
你能告诉我谁会给我们做报告吗?(who是连接代词)

bsp; Show me what you have bought for me? (what 是连接代词,原来的语序是What have you bought for me?)
Please guess which subject I like best?
猜一猜,我喜欢哪一门功课?(which是连接代词,原语序为Which subject do I like best?)
注意:在宾语从句中,其语序为陈述句,其结构为:主句+连接代词+主语+谓语+其他成分。
2.连接副词引导的宾语从句的用法。
Can you tell me where we show our tickets? (where 为连接副词,其语序应当为:Where do we show our tickets?)
你能告诉我我们应当在哪里剪票吗?
Can you tell me how I can get the information? (how 为连接副词,其正常语序为:How can I get the information?)
你能告诉我怎样才能得到那些信息呢?
Do you know why he is often late for school? (why为连接副词,该句语序为:Why is he often late for school?)
你能告诉我他为什么常常迟到吗?
注意:常用于宾语从句中的连接副词主要有: why, how, where, when. 英语中连接副词与疑问代词是相同的。由连接副词引导的宾语从句为:主句+连接副词+主语+谓语+其他成分。
3.以连词if或whether 引导的宾语从句。
I want to know if/whether you have already finished your work..
I'm not sure if/whether you will come to the party tomorrow.
I want to know if/whether you are a teacher.
whether/if 的意思是"是否",在宾语从句中是不能省略的,他们引导的原句都是一般疑问句。也就是说,当你判断该宾语从句的原句本该为一般疑问句,则在改为宾语从句时就应当用whether/if。
