afford常常接在一些助動詞後面,如:can,could,be able to等。afford後面所跟動詞的形式經常是afford to do sth.,可以直接跟名次,但是很少用於被動語態。
- i can't afford so much money for the new car. 我付不起這么多錢買輛新車。
(×)a car can be afforded by most people.
(√)most people can afford a car. 大多數人都能買得起汽車。
[貼心叮嚀]
afford這個單詞非常重要,也經常考,但它的考點並不多。

be afraid to do sth. 害怕/不敢做某事

a. i couldn't agree more  b. i'm afraid not
c. i believe not  d. i don't think so
答案:a (“這個周末去野餐,好嗎?”“再好不過了。我喜歡親近自然。”本題考查的是交際用語。i couldn't agree more是“再好不過了(表示同意 )”;i'm afraid not是“我恐怕不能”; i believe not 和i don't think so表示“我不認為這樣”。)

afraid非常重要,要熟練掌握上面的考點。

這兩個詞有時可以互換。但later可以和具體的時間連用,而afterwards不能。
