下面我們通過分析一句話來看一下大家是否真正掌握了非謂語動詞。

In fact, allowing non-lawyers to own shares in law firms would reduce costs  and improve services to customers, by encouraging law firms to use technology  and to employ professional managers to focus on improving firms’ efficiency.

首先，allowing non-lawyers to own shares in law firms作主語，to own shares in law  firms不定式作賓補(bǔ)。在英語中有些動詞要求接動詞不定式作賓補(bǔ)。它表示該動作發(fā)生在謂語動詞之后，屬將要發(fā)生的動作。有這種用法的動詞常見的有：allow;ask;  tell; get; wish; like; want; expect; prefer; enable; teach; know; understand;  would like; cause; force; know; intend; permit; request; order; invite;  encourage; warn; remind; oblige; forbid; challenge; drive，等。 例如：

Wei Fang asked me to go shopping with her.

(“逛商場”這個動作發(fā)生在“叫”之后。)

然后來看一下encouraging law firms to use technology and to employ professional  managers to focus on improving firms’  efficiency這一個長的動名詞短語，實際上盡管它非常長，但是它只是介詞by的賓語。其中to use technology and to employ  professional managers to focus on improving firms’ efficiency不定式短語是law  firms的賓補(bǔ)，to focus on improving firms’ efficiency不定式短語作目的狀語。

總而言之，由于考研英語閱讀理解和翻譯中，非謂語動詞的考察非常普遍，所以大家一定要能快速識別出非謂語動詞進(jìn)而分析句子。另外，在寫作中，大家也可以使用非謂語動詞來進(jìn)行造句，會讓我們的文章句式更豐富和高級。
