不正確句: Breaking chalk into two pieces is a physical change, there is no change in the composition of the chalk.

　　正確句： Breaking chalk into two pieces is a physical change, so there is no change in the composition of the chalk.

　　II 高分表達

　　除了在句式上長短句相結(jié)合準(zhǔn)確表達外，朗閣海外考試研究中心建議新托福考生要使用一些特殊的句式，以使句型多樣化。句型多樣化也是作文得到高分的條件之一。除了我們之前經(jīng)常提到的高分句式，如倒裝句、強調(diào)句、狀語前置、插入語等，筆者還提出另外一個句式的多樣變化，即主語多樣化。下面筆者將列舉幾個句子概括介紹前面四種句型，而重點分析主語多樣化。

　　正常句： Luck only works in extreme cases.

　　倒裝句： Only in extreme cases does luck work.(否定詞位于句首的倒裝。)

　　正常句： The internet provides people access to the latest information.

　　強調(diào)句： It is the internet that provides people access to the latest information. (強調(diào)the internet)

　　正常句： The environment has been deteriorating severely along with the development of industry.

　　狀語前置句： Along with the accelerating development of industry, the environment has been deteriorating severely.

　　正常句： However, new zoos try to duplicate animals’ natural habitats as much as possible and give animals a comfortable amount of space.

　　插入語： New zoos, however, try to duplicate animals’ natural habitats as much as possible and give animals a comfortable amount of space. (連詞however做插入語)

　　主語多樣

　　1. 她突然想到了一個主意。

　　She suddenly had an idea.

　　通常情況下，考生會馬上對這句話進行翻譯，基本不會動句子結(jié)構(gòu)。但是以人作為主語的英語句子總是不能夠很吸引人，所以這個句子如果稍微做下修改，以后面的賓語“主意”做主語，這個句子會發(fā)生一些變化。

　　An idea suddenly occurred to her.

　　2. 他開車心不在焉，幾乎闖禍。

　　He was absent-minded when driving, and almost caused an accident.

　　這句話依然是拿人做主語，稍微改一下，把心不在焉這個形容詞的名詞形式做主語，會大不相同。

　　His absence of mind during driving nearly caused an accident.

　　3. 美利堅合眾國創(chuàng)立于1789年。

　　The United States of America was founded in 1789.

　　這句話沒有任何錯誤，但是不夠多樣，可以用時間作主語。

　　The year 1789 witnessed the founding of the United States of America.

　　III 實用句型

　　在文章的最后，朗閣海外考試研究中心為大家列舉幾個新托?？荚囍锌梢允褂玫奶子镁湫停瑸橐恍懢渥用恢^緒的考生提供幫助。

　　努力準(zhǔn)備新托福考試是值得的。

　　2. Nothing is more important than to receive education.

　　沒有比接受教育更重要的了。

　　3. The reason why the white-collars suffer increasing work-related stress is that they pursue work achievement in career.

　　白領(lǐng)壓力日益增加的原因是他們在事業(yè)上有所追求。

　　4. It is time the related department took proper measures.
