八年級英語下冊Unit 5知識講解
a: where are you going?
b: i am going for a walk. are you coming with me?
a: yes, i am just coming. wait for me.
2. 現在進行時表示將來和用be going to 表示將來意思比較接近，但是現在進行時更強調事先已安排好，即將去做的事情, 而be going to 一般只表示打算做某事，有做某事的意圖。我們來看兩個例子：
she is having a meeting at 9 tomorrow. 她明天早晨9點有個會。
we are leaving for london next week.我們下周出發去倫敦。
這兩個句子里就是用現在進行時表示將來已經安排好要做的事情。
iv. 重點難點分析
1. too much 和 much too
too much 后接不可數名詞，用來表示數量太多，意思是“……太多了（數量多）”；much too后接形容詞，用來說明程度的，意思是“太……（程度深）”如：
much too heavy 太重了 （表程度）
錯誤：he has drunk much too water.
正確：he has drunk too much water. 他喝了太多的水。（修飾不可數名詞，表數量）
2. be famous for 和 be famous as
be famous for表示“因……而出名”， for后接表示出名的原因；be famous as則表示“以……身份而著名”，as 后接職業、身份或地位，表示作為……職業、身份或地位是著名的，如：
france is famous for its fine food and wine. 法國以其佳肴和美酒著名。
france is famous as a romantic country. 法國作為一個浪漫的國家而出名。
3. i want you to remember the rules for school parties.
我想讓你記住參加學校聚會的規則。
want sb. to do sth. 想讓某人做某事
4. travel around the world 周游世界
e.g. her dream is to travel around china. 她的夢想是周游全中國。
5. if we have it today, half the class won’t come.
如果我們今天開聚會，全班有一半的同學將不來參加。
won’t 是 will not 的縮寫
if 從句用一般現在時，表示假設，主語用一般將來時。
6.reasons for becoming a professional athlete 贊同成為一名職業運動員的理由
for prep. （表示贊成、支持），其反義詞為against

7.reasons against becoming a professional athlete 反對成為一名職業運動員的理由。

注意：介詞后面用名詞或動詞ing的形式
eg. are you against my plan? 你反對我的計劃嗎？

8.begin the story with the words.以這些話開頭講這個故事。
