　　短語部分沒有獨(dú)立主語，則短語結(jié)構(gòu)稱為非謂語動詞。

　　非謂語動詞的結(jié)構(gòu)：分詞(分詞短語)

　　句子的主語決定非謂語動詞中的分詞是用主動還是被動形式。如果是句子的主語發(fā)出動作，則使用現(xiàn)在分詞;如果動作不是由句子的主語發(fā)出，則使用過去分詞。

　　remember to do sth. 記得要去做某事; remember doing sth. 記得做過某事;

　　非謂語動詞與獨(dú)立主格：短語，句子(或者句子，短語)

　　當(dāng)短語部分有獨(dú)立主語，并且該主語不同于句子主語，這時短語結(jié)構(gòu)稱為獨(dú)立主格。(它最明顯的特點(diǎn)是短語部分有獨(dú)立的主語)。

　　獨(dú)立主格的結(jié)構(gòu)1：名詞(代詞)+ 分詞 [現(xiàn)在分詞、過去分詞]

　　現(xiàn)在分詞表示主動的，正在進(jìn)行的行為;過去分詞表示被動的，已經(jīng)完成的行為。作題時要通過判斷動作與名詞(代詞)之間的關(guān)系來確定是使用現(xiàn)在分詞還是過去分詞。當(dāng)動作由名詞(代詞)發(fā)出時使用現(xiàn)在分詞，而名詞(代詞)是受動者時則用過去分詞。

　　1. Silver is the best conductor of electricity， copper _B_ it closely.

　　2. All things _A_， the planned trip will have to be called off.

　　A to be encouraged B been encouraged C being encouraged D be encouraged

　　as well as 和(相當(dāng)于and); be encouraged不會考。

　　動詞不定式有預(yù)示將來行為的含義。to be encouraged 將要被鼓勵;

　　been encouraged 已經(jīng)被鼓勵完了，與主句的謂語動詞相對;being encouraged 正在被鼓勵

　　短語部分沒有獨(dú)立主語，則短語結(jié)構(gòu)稱為非謂語動詞。
