2. _____many times , he still couldn't understand it .

A.Having been told B. ToldC. He was told D. Though he had been told

分析：句1. 用連詞but 引導(dǎo)并列句子，因此，前面與后句一樣也是個(gè)

獨(dú)立句子成分，故選C。 句2. 句中用逗號(hào)隔開(kāi),且無(wú)連詞引導(dǎo)，因此，前面不是句子結(jié)構(gòu)，

只是句子的一個(gè)成分，故選A，用非謂語(yǔ)動(dòng)詞作狀語(yǔ)。

二. 非謂語(yǔ)動(dòng)詞的邏輯主語(yǔ)分析技巧

確定要選非謂語(yǔ)動(dòng)詞之后，第二步要分析其邏輯主語(yǔ)。非謂語(yǔ)動(dòng)詞雖不能作謂語(yǔ)，但仍具有動(dòng)詞特點(diǎn)，其邏輯上的動(dòng)作執(zhí)行者就叫做邏輯主語(yǔ)。非謂語(yǔ)動(dòng)詞作狀語(yǔ)時(shí)，其邏輯主語(yǔ)須和句子的真正主語(yǔ)一致。若不一致，則須加上自己的邏輯主語(yǔ)。

First ____ to the market, these products enjoyedgreat success.

A. introducing B. introduced C. introduce D. being introduced

分析: 非謂語(yǔ)動(dòng)詞的邏輯主語(yǔ)是: these products,與句子的主語(yǔ)一致, 故選B

1._______no buses , we had to walk home.

2. ______Sunday, I shall have a quiet day at home .

A. There being B. It were C. There were D. It being

分析：句1. 表示“沒(méi)有公共汽車”，應(yīng)用“there be”結(jié)構(gòu)，

即邏輯主語(yǔ)是“there”，故選A 。 句2. 同理選D。
