套句展示：

　　It is necessary that effective actions be taken to prevent this problem.

　　省略，在語(yǔ)言中，尤其在對(duì)話中是一種常見的現(xiàn)象，它可以使語(yǔ)氣明了。英語(yǔ)里被省略部分一般可以在句子中補(bǔ)上。本句是省略should的虛擬語(yǔ)氣，完整句為It is necessary that effective actions should be taken to prevent this problem. 這種對(duì)虛擬語(yǔ)氣的省略在四級(jí)作文句子里面廣為存在，

　　又如：It is hoped that great efforts should be directed to (expended on / focused on) finding (developing / improving)…中的should也可省略。

　　必考句型：

　　(1) Although many have tried, few have succeeded in attempts to .

　　【分析】本句中tried后的賓語(yǔ)可根據(jù)后半句的語(yǔ)義推測(cè)得知，所以可以省略，避免重復(fù)。

　　Although many have tried, few have succeeded in attempts to find perfect solutions.

　　(2) , be it , will bring a lot of happiness into our lives.

　　【分析】本句是一個(gè)超難句型，中間一節(jié)省略了whether和might，并進(jìn)行了倒裝，將“be it”恢復(fù)后應(yīng)為whether it might be。Be it…，可譯為“比方說”，用來給出更多細(xì)節(jié)。

　　The application of electric power, be it to light our rooms or to listen to music, will bring a lot of happiness to our lives.

　　(3) Christie stared angrily at her boss and turned away, as though to go out of the office.

　　【分析】as though引導(dǎo)方式狀語(yǔ)從句，謂語(yǔ)常用虛擬語(yǔ)氣，本句中主句的主語(yǔ)與從句的主語(yǔ)相同，故從句中的主語(yǔ)和謂語(yǔ)省略，即省略了she wanted;如果補(bǔ)全，即為：as though she wanted to go out of the office.

　　偉人偉招：

　　1. 以退為進(jìn)式

　　On earth there is nothing great but man; and in man there is nothing great but mind. (Hamilton )

　　世界上，沒有什么比人更偉大，而對(duì)于人來說，沒有什么比精神更偉大。

　　【點(diǎn)評(píng)】在你考試寫作文時(shí)，也可以用這種方式來分步把你的觀點(diǎn)說出來，這種句子體現(xiàn)了一種智慧上的美。另外nothing but…(只有…)句型我們要熟練掌握。

　　I have nothing but compassion for your situation.

　　Nothing but determination will get us through this.

　　2. 精力無窮式work as though your strength were limitless. (S. Bernhardt )

　　要這樣生活，仿佛你壽命永恒;要這樣工作，仿佛你精力無窮。(波恩哈特)

　　【點(diǎn)評(píng)】是個(gè)很生動(dòng)的句型，很有文學(xué)魅力，可以背會(huì)用來鼓勵(lì)大家努力。用在最后一段的開頭，可以畫龍點(diǎn)睛。

　　3. 前輕后重式

　　不要認(rèn)為取勝就是一切，更重要的是要有信念。倘若你沒有信念，那勝利又有什么意義呢?(柯克蘭)

　　【點(diǎn)評(píng)】這是正反論述文的經(jīng)典句型。前面的觀點(diǎn)是你反對(duì)的，后面的是你所支持的。例如在文章的最后一段可以這樣寫：Don’t be afraid that we won’t succeed in solving this problem; it is more important to know we are doing our best. 這樣，20多個(gè)單詞就毫不費(fèi)力地寫出來了。
