better.

　　如果再精心一些,这些大白菜还可以长得更好.

　　相当于if, unless引导的从句.

　　4. 作让步状语：

　　Beaten by the opposite team, the players were not discouraged.

　　(Though they were beaten by the opposite team, the players were not discouraged.)

　　相当于though, although引导的从句

　　5.作方式或伴随情况状语.

　　The hunter left his house , followed by his dog.

　　猎人离开了屋子,后面跟着他的狗.

　　She sat by the window, lost in thought.

　　她坐在窗前,陷于沉思.

　　作状语表示方式或伴随情况时,过去分词可用并列句代替.如:

　　The hunter left his house, followed by his dog. (= He was followed by the dog. )

　　注意：1. 过去分词作状语表示被动的和完成的动作.

　　(1) Written in a hurry, this article was not so good! 因为写得匆忙,这篇文章不是很好.

　　【注意】written 为过去分词作状语,表示这篇文章是被写的,而且已经被写. 值得注意的是,有些过去分词因来源于系表结构,作状语时不表被动而表主动.这样的过去分词及短语常见的有: lost (迷路); seated (坐); hidden (躲); stationed (驻扎); lost / absorbed in (沉溺于); born (出身于); dressed in (穿着); tired of (厌烦).

　　(2) Lost / Absorbed in deep thought, he didn't hear the sound.

　　因为沉溺于思考之中,所以他没听到那个声音.

　　2. 过去分词作状语时其逻辑主语为主句的主语,此时应注意人称一致.

　　(1) Given another hour, I can also work out this problem.

　　再给我一个小时,我也能解这道题.

　　(given 为过去分词作状语,它的逻辑主语为主句主语 I ,即 I 被再给一个小时.)

　　(2) Seen from the top of the hill, the city looks more beautiful to us.

　　从山顶看城市,城市显得更漂亮.

　　(seen 为过去分词作状语,表"被看",由语境可知,它的逻辑主语必须是城市,而不是"我们",因为"我们"应主动看城市.)

【注意】如果过去分词作状语时,前面再加逻辑主语,主句的主语就不再是分词的逻辑
