三、语言点详解
（一）动名词作主语
动名词（动词 -ing形式）可以在句子中作主语，谓语动词用单数形式。
例句：Eating an apple a day keeps the doctor away.（一天吃一个苹果，医生远离我。）
Reading books is a good hobby.（读书是个好习惯。）
（二）形容词修饰不定代词的用法
形容词修饰不定代词（如something, anything, nothing, someone等）时，要放在不定代词的后面。
例句：There is something wrong with my stomach.（我的胃有点不舒服。）
Do you have anything important to tell me （你有什么重要的事情要告诉我吗？）
（三）be good for、be bad for与be harmful to的区别
be good for：对……有好处。
例句：Doing sports is good for your body.（做运动对你的身体有好处。）
be bad for：对……有害，与be harmful to意思相近。
例句：Staying up late is bad for your health.（熬夜对你的健康有害。）
Smoking is harmful to your lungs.（吸烟对你的肺部有害。）
（四）enough的用法
enough作形容词，意为“足够的”，修饰名词时，放在名词前。
例句：We have enough food for the party.（我们为派对准备了足够的食物。）
enough作副词，意为“足够地”，修饰形容词或副词时，放在形容词或副词后面。
例句：He is old enough to go to school.（他足够大了，可以去上学了。）
（五）such as与for example的区别
such as：用来列举同类人或事物中的几个例子，可与and so on连用，放在被列举的事物之前。
例句：I like fruits such as apples, bananas and oranges.（我喜欢水果，比如苹果、香蕉和橙子。）
for example：一般只举同类人或事物中的一个为例，作插入语，用逗号隔开，可位于句首、句中或句末。
例句：For example, my brother likes playing basketball.（例如，我哥哥喜欢打篮球。）
My brother likes playing ball games. For example, he likes playing basketball.（我哥哥喜欢球类运动。例如，他喜欢打篮球。）
（六）instead与instead of的区别
instead：副词，意为“代替；反而”，通常放在句末，前面有逗号隔开；也可放在句首，后面有逗号隔开。
例句：He didn't go to the park. He went to the library instead.（他没有去公园。相反，他去了图书馆。）
Instead, he decided to stay at home.（相反，他决定待在家里。）
instead of：介词短语，意为“代替；而不是”，后面接名词、代词、动名词或介词短语等。
例句：I'll go to the party instead of him.（我将代替他去参加派对。）
She likes reading books instead of watching TV.（她喜欢读书而不是看电视。）
（七）a little与a few的区别
a little：修饰不可数名词，表示“一点儿；少量”。
例句：There is a little milk in the glass.（杯子里有一点儿牛奶。）
a few：修饰可数名词复数，表示“几个；少数”。
例句：I have a few friends in this city.（我在这个城市有几个朋友。）
四、语法聚焦
（一）一般现在时（表示饮食习惯和日常行为）
一般现在时表示经常性、习惯性的动作或现在的状态。
当主语是第三人称单数（he, she, it等）时，动词要加 -s或 -es。
例句：He often eats junk food.（他经常吃垃圾食品。）
She usually drinks milk in the morning.（她通常早上喝牛奶。）
在一般现在时的否定句和疑问句中，要借助助动词do或does。当主语是第三人称单数时，用does，动词还原；其他人称用do。
例句：I don't like vegetables.（我不喜欢蔬菜。）
Does she have breakfast every day （她每天都吃早餐吗？）
（二）可数名词与不可数名词
可数名词有单数和复数形式。复数形式一般在词尾加 -s，以s, x, ch, sh结尾的名词加 -es；以辅音字母加y结尾的名词，变y为i再加 -es；以f或fe结尾的名词，变f或fe为v再加 -es等。
例句：apple - apples, box - boxes, watch - watches, family - families, knife - knives
不可数名词没有复数形式，不能直接用数字修饰。表示数量时，常用“数词 + 量词 + of + 不可数名词”结构。
例句：a glass of water（一杯水），two pieces of bread（两片面包）
