【易混辨析】house, family ,home   
(1)house一般指所居住的建筑物，即“房子，住宅”.

(2)family着重指家庭成员.
My family are au here．我们一家都在这儿.

5. a lot of, many, much 
    三者都可表示“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一般不用于否定句和疑问句中，在这两类句子中要用many或much.
6.kind of
    kind of后接形容词或副词，意为“有点，有几分”.

7．Maybe ,perhaps, likely possible, probably
maybe. perhaps和probably都有“也许，大概”的意思.perhaps也许，大体和possibly同义；probably大概，肯定的成分较大，是most likely的意思；possibly可能，常和call，may，must等情态动词连用，比probably语气弱得多；maybe或许，比perhaps普通，但不庄重；
likely或许，通常与most，very连用.
8．although , though   
although和though作连词用，意为“尽管，虽然”，二者可以通用.
良友Although／Though they are so poor ,they have enough to eat·他们虽然穷，食物还是够吃的.
注意：在一个句子中，用了although或though就不能用but了，用了but则不能用although或though，即：“虽然……但是……”不见面，但是可以用yet.
9．hard, hardly   
hard既可作形容词，也可作副词，其词义丰富；hardly是具有“几乎没有，几乎不”这种否定含义的独立副词.
