Question

新概念3册39课中一个句子分析，谢谢。

Bruce went into a low gear and drove at a terrifying speed,keeping the front wheels astride the crack as he followed its zigzag course. keeping the front wheels astride the crack as he followed its zigzag course是方式状语修饰drove，as是连词引导从句么？是什么从句？astride the crack 做什么成分？

Answer 1

keeping the front wheels astride the crack as he followed its zigzag course不是方式状语

应该这样来理解:

keeping the front wheels astride the crack 是现在分词短语作伴随状语, 表示与drove的动作同时发生.

as he followed its zigzag course是时间状语从句,"当...的时候"

astride the crack 是介词短语作现在分词短语结构中的宾补. (其宾语是 the front wheels )

句意: 布鲁斯接通了低速挡,开车速度快得令人害怕; 他在使前轮分跨地裂的同时曲曲折折地前进.

追问

1.我也认为as引导时从。
2.我依然认为是方式状语，因为keeping the front wheels astride the crack as he followed its zigzag course是Bruce开车的方式，伴随状语的话我个人认为是这样理解的，举个例子，我吹着口哨干活，吹口哨就是伴随状语；我用斧子干活就是方式状语。····可能我方式状语和伴随状语有些混淆。有待商榷。
3.keeping是非谓语动词吧？那怎么会有宾语和宾补呢？

追答

你是根据语意来理解的,因此很容易把keeping the front wheels astride the crack
当成方式状语.

而从语法角度来说, 应为伴随状语. 如果你非要认为它是方式状语也未尝不可,
只要能帮助你理解语意就可以.

其实,管它是方式状语还是伴随状语并不重要, 重要的是把句子的意思弄懂.

我认为, 学英语不必死扣语法,除非你是语法学家.

非谓语动词是可以带宾语及宾补的哟,如现在分词,不定式.

例: It's important for me to learn English . (English作 to learn的宾语)

Considering your health , you'd better have a rest .(your health 作Considering 的宾语)

People separate their rubbish to make it easier for it to be reused .
(第一个it作不定式 to make 的宾语, easier作宾补)
