妙招四  用作結(jié)果狀語(yǔ)時(shí)，可用現(xiàn)在分詞或不定式，其原則區(qū)別是：一般要用現(xiàn)在分詞，不定式用作結(jié)果狀語(yǔ)主要用于某些特定句式中

1. The glass doors have taken the place of the wooden ones at the entrance, _________ in the natural light during the day.

A. to let                    B. letting                       C. let                         D. having let

【解析】答案選B。此處用現(xiàn)在分詞表示結(jié)果。又如：It rained heavily, causing severe flooding in that place. 大雨滂沱，造成了那個(gè)地方洪水泛濫。

2. Oil prices have risen by 32 percent since the start of the year, _________ a record US$ 57.65 a barrel on April 4.

A. have reached         B. reaching                    C. to reach                D. to be reaching

【解析】答案選B。伴隨著謂語(yǔ)動(dòng)詞的發(fā)生而產(chǎn)生的自然結(jié)果，用現(xiàn)在分詞作結(jié)果狀語(yǔ)。

注：在enough to do sth, too…to do sth, only to do sth等特定句式中，習(xí)慣上要用不定式表示結(jié)果。如：

1. He hurried to the booking office only _________ that all the tickets had been sold out.

A. to tell                    B. to be told                   C. telling                    D. told

【解析】答案選B。only to do sth在此表示出人意料的結(jié)果。

2. He hurried to the station only _________ that the train had left.

A. to find                   B. finding                      C. found                    D. to have found

【解析】答案選A。only to do sth在此表示出人意料的結(jié)果。

妙招五  凡是含有被動(dòng)意義時(shí)，原則上要用過(guò)去分詞。但是，如果所涉及的動(dòng)作尚未發(fā)生，則用不定式的被動(dòng)式；如果所涉及的動(dòng)作正在進(jìn)行，則用現(xiàn)在分詞的被動(dòng)式

1. The children talked so loudly at dinner table that I had to struggle _________.

A. to be heard            B. to have heard           C. hearing                  D. being heard

【解析】答案選A。根據(jù)句意，此處指的是“被聽(tīng)見(jiàn)”，故要用被動(dòng)式，因此可排除B和C。另外，由于“設(shè)法被聽(tīng)見(jiàn)”為目的狀語(yǔ)，動(dòng)作在當(dāng)時(shí)尚未發(fā)生，故用不定式，即選A。

2.The repairs cost a lot, but it’s money well _________.

A. to spend                  B. spent                    C. being spent           D. spending

【解析】答案選B。由于money與spend之間為被動(dòng)關(guān)系，故用過(guò)去分詞。

3. Five people won the “China’s Green Figure” award, a title _________ to ordinary people for their contributions to environmental protection.

A. being given              B. is given                 C. given                   D. was given

【解析】答案選C。由于title與give之間為被動(dòng)關(guān)系，故用過(guò)去分詞。

妙招六  謂語(yǔ)動(dòng)詞作狀語(yǔ)時(shí)，其邏輯主語(yǔ)原則上應(yīng)與主句主語(yǔ)保持一致

1. Faced with a bill for $10, 000, _________.

A. John has taken an extra job                         B. the boss has given john an extra job

C. an extra job has been taken                         D. an extra job has been given to John

【解析】答案選A。由于(be) faced with的邏輯主語(yǔ)是John，故答案只能選A。

2. While watching television, _________.

A. the door bell rang                                      B. the doorbell rings

C. we heard the doorbell ring                          D. we heard the doorbell rings

【解析】答案選C。因?yàn)?/FONT>watching的邏輯主語(yǔ)一定是we，排除選項(xiàng)A和B；又因在hear后作賓補(bǔ)的是省略了to的不定式，所以選項(xiàng)D中的rings是錯(cuò)誤的。
