3. _________ the years slipped by, I thought less about her.

A. With                   B. As                       C. Since                   D. To

【分析】此題容易誤選 A，而其實(shí)應(yīng)選 B。雖然 with 和 as 均可表示“隨著”，但詞性不同：with 是介詞，后接名詞或代詞，而 as 用于此義時(shí)是連詞，后接句子。比較：

He will improve as he grows older. 隨著年齡的增長，他會(huì)進(jìn)步的。

People’s ideas change with the change of the times. 時(shí)代變了，人們的觀念也會(huì)變化。

下題應(yīng)選答案C，你知道是什么原因了嗎？

_________ the development of modern agriculture and industry, more and more waste has been produced.

A. As                       B. For                      C. With                    D. Through

4. He walked _________ the stage and bowed to the audience.

A. across                  B. cross                    C. crossing               D. acrossing

【分析】此題容易誤選B。across 和 cross 均可表示“橫過”、“穿過”，但詞性不同：across 是介詞，cross 是動(dòng)詞。比較：

cross the street 橫過馬路                          walk across the street 走過馬路

cross a river 過河，渡河                          swim across a river 游過河

【分析】此題正確答案應(yīng)為A。請(qǐng)?jiān)倏匆焕?SPAN style="FONT-FAMILY: 'Times New Roman'; FONT-SIZE: 10.5pt; mso-fareast-font-family: 宋體; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US>(www.hz123456.com)：

Don’t _________ the bridge until you come to it.

A. across                  B. cross                    C. through                D. over

【分析】此題最佳答案選B，從題干的句子結(jié)構(gòu)來看，填空處只能填一個(gè)動(dòng)詞，而在所給的四個(gè)選項(xiàng)中，只有B為動(dòng)詞，其余三個(gè)均為介詞。

5. A _________ road goes _________ from one place to another.

A. straight, straight            B. straightly, straightly 

C. straight, straightly         D. straightly, straight

【分析】此題容易誤選C，認(rèn)為第一空是用于road 前作定語，故用形容詞straight(這是對(duì)的)；第二空應(yīng)填副詞 straightly，用以修飾動(dòng)詞goes(這就不完全對(duì)了)。在現(xiàn)代英語中，straight 既可用作形容詞，也可用作副詞。straightly這個(gè)副詞形式在現(xiàn)代英語中已被廢棄，許多詞典均不再收錄此詞。所以此題最佳答案應(yīng)選A。

6. He knew she was crying _________ what he had said to her.

A. because               B. because of           C. since                   D. as

【分析】此題容易誤選 A，因?yàn)橐话阏J(rèn)為：because 是連詞，后接句子；because of 是復(fù)合介詞，后接名詞、代詞、動(dòng)名詞等。而其實(shí)此題應(yīng)選 B，盡管 what he had said to her 是一個(gè)句子，但它卻是一個(gè)比較特殊的句子，即它是一個(gè)由 what 引導(dǎo)的名詞性從句，在本質(zhì)上相當(dāng)于一個(gè)名詞(即相當(dāng)于 the thing that he had said to her)，而從屬連詞 because 用以引導(dǎo)一個(gè)句子時(shí)，它應(yīng)引導(dǎo)一個(gè)原因狀語從句。

7. He fell down to the ground, his mouth _________ and eyes _________.

A. open, close          B. opened, closed  C. opened, close         D. open, closed

【分析】此題很容易誤選A，其實(shí)應(yīng)選 D。open 和 close 均可用作動(dòng)詞，前者表示“開”，后者表示“關(guān)”，是一對(duì)反義詞，如：Please open your mouth.(請(qǐng)張開嘴)，Please close your mouth. (請(qǐng)閉上嘴)。但是 open 和 close 也可用作形容詞，此時(shí)前者意為“開著的”，后者意為“接近的”、“親近的”等，而并不表示“關(guān)著的”，要表示“關(guān)著的”，英語用 closed，即用作形容詞時(shí)，open 與close 不是一對(duì)反義詞，而與 closed 才是反義詞。
