【词语辨析】
1. good, fine, well与nice这几个形容词都有“好”的意思。
（1）good是通用词，可以表示各种品质方面的优异，从美学到道德规范几乎都可以使用。
It’s an old film, but it’s very good. 那是一部老电影，但是很好。
（2）fine表示“上好的，精细的”，也可以表示“美好的”，天气“晴朗的”。
She always wears fine clothes. 她总穿好衣服。
It is fine sand. 这是细沙。
It is a fine day today. 今天天气晴朗。
（3）well表示身体“无病的，健康的”。
You look very well, Jimmy. 你看上去很好，吉米。
He’s better, thank you, doctor. 他好些了，谢谢你，医生。
（4）nice表示使人感到“愉快的，好的”。这几个词虽然都有“好”的意思，但是只是近义词，而且初学者不易掌握。
These ice-creams are nice. 这些冰淇淋真好。
He’s a very nice man. We shall miss him. 他是个很好的人。我们会想念他的。
She is a very nice girl. 她是个很好的姑娘。
注意：
nice and = very, rather
It’s nice and warm in here. 这里面很暖和。
2. home, house和family三者都可表示“家”，但所指不同。
（1）house一般指所居住的建筑物，即“房子；住宅。”
His house was burned in a big fire. 他的家在一场大火中被烧了。
（2）family着重指家庭的成员。如：
My family are all fond of music. 我们一家人都喜欢音乐。
（3）而home则指某人出生及生活的那个环境，包括住处及家人。如：
He left home at the age of 18. 他十八岁离开了家。
homework 家庭作业；课外作业
He usually does his homework after school. 他通常放学后做作业。
hometown 家乡；故乡
—Where’s your hometown? 你的家乡在哪里？
—It’s in Suzhou. 在苏州。
homeland 祖国；本国
I love my homeland—China. 我爱我的祖国——中国。
3. maybe, perhaps, likely, possibly与probably
perhaps也许，是也许如此也许不如此的意思，大体和possibly同义
probably大概；肯定的成分较大，是most likely的意思
possibly或者，常和can, 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。如：
Most likely she is over thirty. 她也许已经30多岁了。
4. maybe与may be
maybe连在一起是副词，意为“可能；也许；大概”，在句中作状语，通常置于句首，也可以放在谓语动词之前。may be分写是“情态动词+动词原形”的形式，意为“可能是；也许是”，在句中作谓语。试比较：
Maybe he will come, maybe he won’t. 他也许来，也许不来。
—Is that true? 那是真的吗？
—Maybe, I’m not sure. 也许（可能）是，我说不准。
He may be eighteen. 他可能18岁了。
Maybe your book is at home. 也许你的书在家里。
The book may be in the desk. 那本书可能在课桌里。
5. although与though
although和though作连词用，意为“尽管；虽然”，二者可以通用。如：
Although / Though they are so poor, they have enough to eat.
他们虽然很穷，食物还是够吃的。
在一个句子里，用了although或though，就不能用but，用了but，则不能使用although或though，即“虽然……但是……”不见面，但可用yet。如：
Although (Thought) it was very cold, (yet) he went out without an overcoat. = It was very cold, but he went out without an overcoat.
尽管外面很冷，但他没有穿大衣就出去了。
