形容詞 able 的語法特點與用法要點
■本站特約作者 陳根花 1. 表示“有能力的”、“能干的”,可用作表語或定語。如: He is an able manager. 他是位有能力的經理。 He is old but still able. 他雖年老,但仍有很能干。 2. 用于 be able to do sth (能或會做做某事)。如: He is able to speak English. 他會說英語。 Everyone here is able to type. 這兒的每一個人都會打字。 He will be able to get about in a week or two. 再過一兩個星期左右他就能走動了。 He studied hard and was able to pass his examinations. 他學習很努力,所以考試及了格。 注:be able to 不僅有多種時態形式(通常不用于進行時或與 be going to 連用),而且還可以與某些情態動詞連用(通常不與 can 連用),甚至還可以有非謂語形式。如: Since his accident he hasn’t been able to leave the house. 自出事之后,他一直未能離開家。 You might be able to persuade him. 你也許能夠說服他。 I hope to be able to do the work. 我希望能干得了這項工作。 I regret not being able to help her. 我很遺憾未能幫助她。 3. able 的比較級和最高級通常是 abler 和 ablest,也可以是 more able 和 most able,有時還可用 better able 和 best able。如: You are better able to do it than I (am). 你比我更有能力做這件事。 She’s the person best able to cope. 她是個最能妥善處理問題的人。 4. 若要加強語氣,其前除可 very, quite, perfectly 等修飾外,有時還可用 well 修飾。如: He is quite [well] able to take care of himself. 他完全有能力照顧自己。 He’s a very able student; he’s just too lazy. 他是個很有能力的學生,只是太懶了。 若受 just, only just 修飾,則表示“只能”“僅能”。如: I was just able to make out a dark figure in the distance. 我只能看見遠處有個黑影。 5. able 的反義詞是 unable(不能的,不會的),不是 disable,后者是動詞,其意為“使殘廢”“使無能力”。比較(www.hz123456.com): They were unable to reach a decision. 他們沒法做出決定。 Now that he was disabled, his house had become a prison to him. 因為他殘廢了,他的房子就成了他的牢籠。 |
