1. |A for a start为固定短语, 意为“首先”.这句话就是说“首先我们没有足够的钱买车”.
2. A attach oneself to 为固定结构,表示“和某人一起花大量时间做事”.本句意为“他经常和那群爬山者在一起(爬山)”.
3. D see sb. do表示看到某人做了某事(通常是看完了整个过程),see sb. doing表示看到某人时他正在做某事,强调动作正在进行(一般只看到了动作的一部分).本句为被动语态,如果改成主动语态就非常容易理People last saw the missing boy playing near the river.意为“人们最后看到那个失踪的孩子时,他正在河边玩”,即人们看到他时,“玩”这个动作正在发生.
