Unit3 SectionB 教材知识详解1. .Could I invite my friends to a party?我能邀请我的朋友们来派对吗？invite用作及物动词，常用构造：invite sb. to some place邀请某人去某地；invite sb. to do sth.邀请某人去故某事。

invite相当于ask。

如：We should invite our teacher to join in our party.我们应该邀请我们的教师参加聚会。

2.Kids these days already have enough stress from school.如今，孩子们已经承受了来自学校的足够多的精神压力。

enough stress足够多的精神压力。

stress为不可数名词，意为“精神压力；心理负担。

〞enough作形容词，修饰名词时，可放在名词的前面，也可以放在名词的后面，习惯放在名词的前面。

enough作副词时，要放在形容词/副词后，即后置。

如：We have enough money to buy a car.我们有足够的钱买一辆车。

3. Housework is a waste of their time.做家务是在浪费他们的时间。

a waste of为固定短语,意为“浪费〞，waste在这里作名词。
