1.看样子你没懂这题的意思.这句话是说：他们要在星期五去上海,我们去火车站送他们好吗?see sb off是送人的意思.他们还没走,当然用将来时,怎么能用完成时呢?
2.这是个被动语态,调整过来就是we must speak to old man politely.speak to 固定搭配啊
3.weather不可数名词也,怎么能用a
4.其实why not 和why don't you 没啥区别,都是“为什么不”的意思,但是其后都必须加动词原形.而这题里why not 后没原型的,只能用don't you join
5.其实有时候有些词组固定用法用惯了,就会忘记了其原来的意思.这题就是,并不是取其表时间的意义而是取其原意,有时候就是这样,要注意啊

1.从后面的shall可以知道这句子是将一般将来时的，所以前面应该用一般将来时而不是现在完成时，再者，left是非延续性动词，在现在完成时里应该改为be away
2.to在这里表目的，这是我的理解
3.such是形容词，修饰名词或名词词组。such的搭配是：such a + n. fine是形容词，所以只能用such，不加a
4.why not do sth.=why ...

4.why not do sth.=why don't you do sth. 这道题，关键就在于那个动词，d选项里面的搭配完整，其他选项里面都不完整或者错误
5.how long一般用来说明时间的长短，如果要表示具体的时间可以用when或者what time

1、see sb off 是送行的意思，所以根据题意，他们还没有走，所以要用一般将来时。
2、这句话的意思是：要有礼貌的向老年人说话，也就是老年人要被有礼貌地向他说。TO有一个“向着、朝着”的意思。所以要选A
3、why not do =why don't you do
4、how long 不仅仅可以表示时间，还可以表示距离、长度啊。所以在这里，其他三个都不合适，只能选C...

答案d，c为什么不可以
--答案C表示已经离开了，离开了还见什么？？？
Old people must ( )

答案a，那个to为什么要有啊？c为什么不可以
--我认为c也可以，可能是一些固定用法。
It was （ ）weather that they decide to go out for a picnic。
A such fine B such a fine
答案A，为什么没有a
--Weather是不可数名词，绝对不能加a.
-I don not have a parner to play table tennis with.
-why ( )a sport club to practise a lot?
A don't join B not joining C not to join D don't you join
答案d，请教why not 和why don't you 的区别
--Why not 和 Why don't you的区别在于后者有YOU（有了you这个主语才能构成句子，否则就是病句。)
（ ）are you gong to write this story ?
-about five pages
A how often B how soon C how long D how fast
答案c，how long 表时间为什么可以说明故事的长短，可以表具体吗？
--How long可表示很多东西的长短？为什么不能表示故事的长短？不可以表你认为的所谓的具体。
