我爸妈比较喜欢住在乡下。那儿的街道比较干净。空气较新鲜，人也比较好，比较友善。而且，都市里比较忙碌，也比较吵。不过最重要的是，住在乡下较安全。我爸妈都相信这句格言：“安全至上。”

III. Grammar Points 语法重点
本课仍侧重于形容词比较级的变化。如clean变成cleaner(更清洁的)、busy变成busier(更忙碌的)、noisy变成noisier(更吵闹的)、safe变成safer(更安全的)等。有关变化的原则，请参考Lesson 51的语法重点。
prefer的用法
a. prefer to+动词原形 比较喜欢·····
例: I prefer to listen to music.
(我比较喜欢听音乐。)
b. prefer to+动词原形+rather than+动词原形
喜欢······胜于·····
此处rather than视为并列连词，表示"而非"之意，连接两个动词原形。
例: I prefer to listen to music rather than watch TV.
(我喜欢听音乐胜于看电视。)
c. prefer+名词+to+名词 喜欢······胜于·····
此处to是介词，有"针对"的意味，"prefer A
to B"表示"就A和B而言，比较喜欢A"。
例: I prefer music to movies.
(我喜欢音乐胜于电影。)Besides, it is busier and noisier in the city.
(而且，城市里比较忙碌，也比较吵。)
此处的it是代词，泛指某地的环境。使用这个it时，句尾一定有一个表示场所的介词短语。
中文：房间里很闷。(stuffy ['stʌfi] a.闷热的)
英文: In the room is stuffy. ( X )
理由：in the room是介词短语，不能作主语。只有名词或代词方可作主语。
改正: It is stuffy in the room. ( O )
说明：此处It指引司里的环境。... it is safer to live in the country.
(···住在乡下较安全。)
初学英文的人容易将这句中文译成:
Live in the country is safer. ( X )
这当然是错误的句子，因为动词不可以直接作主语。
动词应变成不定式(即to+动词原形)或动名词(即动词字尾加-in名)方可作主语。故上句中的动词应变成To live或Living才合语法。即
To live in the country is safer. ( O )
= Living in the country is safer.
(住在乡下较安全。)
但这种不定式或动名词短语所形成的主语往往过大，故写作的人经常用it代替这些过大的主语，不定式或动名词短语则移至句尾，此时动名词亦常改为不定式。即
To live in the country is safer. ( O )
=It is safer to live in the country. ( 佳 )
Living in the country is safer. ( O )
=lt is safer living in the country. ( 佳 )
=It is safer to live in the country. ( 佳 )
了解上面的说明后，我们不妨试译下列中文句子中文：学英文很有趣。
英文: Learn English is interesting. ( X )
→ Learning English is interesting. ( O )
=lt is interesting to learn English. ( 佳 )believe可作及物或不及物动词。believe作及物动词时，之后直接接宾语。believe若作不及物动词时，须接介词in之后，方可接宾语。区别如下
believe+宾语 相信某人/某人的话
believe in+宾语 坚信某格言/信仰某宗教/相信某种神的存在(强调信仰或信念)
例: I believe him.
(我相信他。)
I believe what he says.
(我相信他的话。)
He believes in Buddhism.
(他信奉佛教。)
Do you believe in God?
(你相信上帝的存在吗?)
I believe in the saying,"Live and learn."
(我认为：“活到老，学到老。”这句格言很有道理。)
