5. a lot of, many, much
三者都可表达“许多”，a 10t 0f既可修饰可数名词，也可修饰不可数名词；many修饰可数名词复数；much修饰不可数名词.
We have a lot of friends．---We have many friends．我们有许多朋友.
Do you have a lot of money?=Do you have much money?你有许多钱吗?
在修饰可数名词复数时，a lot／lots of可与many互换；在修饰不可数名词时，alot／lots of可与much互换.但a lot／lots of一般不用于否认句和疑问句中，在这两类句子中要用many或much.

7．Maybe ,perhaps, likely possible, probably
maybe. perhaps和probably均有“也许，大概”旳意思.perhaps也许，大体和possibly同义；probably大概，肯定旳成分较大，是most likely旳意思；possibly也许，常和call，may，must等情态动词连用，比probably语气弱得多；maybe或许，比perhaps一般，但不庄严；
likely或许，一般与most，very连用.
8．although , though
although和though作连词用，意为“尽管，虽然”，两者可以通用.
Although／Though they are so poor ,they have enough to eat·他们虽然穷，食物还是够吃旳.
注意：在一种句子中，用了although或though就不能用but了，用了but则不能用although或though，即：“虽然……不过……”不会面，不过可以用yet.
