1. could you tell me if he will

could you tell me __whether____ he will come here tomorrow?
  用whether比较合适
  whether和if的区别
  一、if或whether引导宾语从句时,作“是否”讲,常放在动词ask 、see 、say 、know和find out等后面.一般情况下,两者常可换用,在口语中多用if.如:
  二、if或whether引导宾语从句时,要注意三个方面,即连词、语序和时态.
  1 if或whether不能和that 或其它连词(副词)同时使用,也不能省去.
  2 if或whether引导的宾语从句时,虽具有疑问意义,但从句语序应用陈述句语序.
  3 if或whether引导的宾语从句应和主句的时态保持一致.即主句为一般现在时,从句用任一种时态;主句为一般过去时,从句则用过去时中的任一种时态.
  三、if和whether的区别:
  1 在动词不定式之前只能用whether .
  2 在whether …… or not 的固定搭配中.
  3 在介词后,只能用whether.
  4宾语从句放在句首表示强调时,只能用whether .
  5用if会引起歧义时,只用whether.如用whether可避免歧义.

could you tell me if he will

2. could you please tell me if the

解题之前,先来了解下can,could 和 be able to三者的区别与联系.
  1.can的过去式是could,但could 除了可作can的过去式外,还可表比can更委婉的语气,因此在回答由could 表示请求的问句中,不能用could,但可用can.如:
  —Could you lend me a hand?
  —Of course I can.
  2.在表示现在或过去的智力、体力、技能等方面的“能力”时,can,could 常可与be able to互换.如:
  He could (or was able to) swim five miles when he was a boy.
  3.be able to比can有更多的表现形式,如"will be able to","have (has) been able to" "had been able to" 等等.因此be able to常被用来表示can所不能表示的将来或完成的概念.如:
  They will be able to run this machine on their own in three months.他们过三个月就能自己开这台机器了.
  4.在表示成功地做了某事时,不用could,而用was / were able to (或managed to,succeeded in doing sth )来表示.如:
  He was able to (or managed to) finish the job yesterday.
  但是couldn't和wasn't / weren't able to 常可互换.如:
  I couldn't / wasn't able to finish the job yesterday.
  5.与感觉动词连用时,can,could亦可与be able to互换.如:
  We could/were able to smell something burning in the kitchen.
  选项B was able to是过去时 而题中所问对象还未成功完成某事,所以不用过去时态,不符合题意,故B可以排除.
  选项D would 先了解下它的用法与意义
  1.will的过去式.
  例:They said it would be fine.听说天气会很好.(it will be fine的过去式)
  例:I said I do my best.我表示过要尽最大的努力.
  2.(在陈述语气中,表示过去将来时,表示无意识的行动或单纯将来发生的事或动作,指实际情况,一般用于间接引语中)会;将;
  例:he said he not be free that night.他说他那天晚上没有空.
  所以 would be able to 是过去将来时态 不符合题意
  因此选C 
  Could you please tell me if he is able to finish the work on time 
  你能告诉我他是否能够按时完成这项工作吗?

3. could you tell us

B
  where +宾语从句( 正常语序- 主语+ 谓语),B / D
  could you tell us 是 can you tell us 比较礼貌的用法,没必要用过去将来时,排除 D
  不明白的再问哟,请及时采纳,多谢!

could you tell us

4. if you could sew ,

B 
②从句的动作与现在事实相反,而主句的动作与过去事实不符。 如:  
 If he were free today, we would have sent him to Beijing.   
   如果他今天有空的话,我们会已经派他去北京了。  
 If he knew her, he would have greeted her.   
要是他认识她的话,他肯定会去问候她了。

5. I would’t tell you if I did是个什么句子?

I would not tell you if i did
如果我做了,我不会告诉你
这是一个虚拟语气
表明过去没有发生的事情
If you accept my answer
Please give me a thumbs up
Thank you very much


I would’t tell you if I did是个什么句子?

6. could you tell me if he will have me.

C
  if引导的不是条件状语从句,而是宾语从句(即不作“如果”讲),相当于whether,意思是“是否”,从句可以用一般将来时(根据实际需要,是将来发生的情况或动作用将来时)
  宾语从句要用正常语序,即主语+谓语,不需要倒装,所以排除掉A和B
  Could you tell me主句的时态动词虽然是could,但是表示委婉的语气,不是过去时,因此宾语从句不需要用过去时,would是will的过去时,不需要,用Will即可,因此选C

7. what if you cant tell

1.D.in
  2.B.what
