I 準確的句子表達

1. 句型分析

英語的句型包括以下幾種，簡單句、復合句、并列句、并列復合句等。在新托福寫作中，一般使用復合句，輔以并列句和并列復合句，當然肯定要有簡單句，做到長短句相結(jié)合。下面摘抄幾個句子給大家認識并分析一下復合句和并列復合句。

a. Even though I usually know what I have to say， I cannot always express myself correctly in English.

這句話是一個復合句，由even though引導的讓步狀語從句。

b. This challenges me to practice my spoken English， with the result that I can complete the speaking tasks more fluently and quickly.

這句話中是一個復合句。with介詞結(jié)構(gòu)中，有一個that引導的同位語從句對result進行解釋說明。

c. I think this is less than ideal because any differences in opinion become personal conflicts， and therefore that might jeopardize the employee’s job.

上句話是一個并列復雜句。and 連接了兩個句子，是一個并列句;because引導的原因狀語從句。

d. Shallow writing is indicative of weak critical-thinking skills， and such writing， which is often described as “sophomoric”， receives low mark.

這句話同樣是并列復雜句。由and連接兩個句子，成為并列句，再一個which引導的定語從句。

2. 有問題的句子的列舉

考生寫的句子容易出現(xiàn)三個問題：一是使用破碎句，二是使用接連句，三是句子連接不正確。

1). 破碎句

所謂破碎句，就是句子不完整，通常是沒有謂語(或者說謂語是動詞的非謂語形式，如分詞)，或者是從句單獨成句。

破碎句：She singing alone. (無謂語，singing是現(xiàn)在分詞)

正確句：She is singing alone.

破碎句：He did not come. Because he was sick. (從句單獨成句)

正確句：He did not come because he was sick.

2).接連句

所謂接連據(jù)，就是兩個句子直接連在一起，既未使用連詞，也未使用正確的標點符號。

接連句：Professionals such as lawyers or accountants usually work longer hours than factory workers they have greater freedom in planning their time.

正確句一：Professionals such as lawyers or accountants usually work longer hours than factory workers. However， they have greater freedom in planning their time.

正確句二：Professionals such as lawyers or accountants usually work longer hours than factory workers; however， they have greater freedom in planning their time.

3).句子連接不正確

所謂句子連接不正確，就是兩個獨立的句子之間以逗號連接，這是不合英語語法的。正確的做法是以連詞、分號、冒號、句號等連接兩個句子。

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)合準確表達外，建議新托?？忌褂靡恍┨厥獾木涫剑允咕湫投鄻踊?。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)

2. Judging from the reams of evidence presented, we can safely conclude that the Three Gorges Project will change the lives of an untold number of people forever.

根據(jù)現(xiàn)有的大量證據(jù)，我們可以有把握地得出這樣的結(jié)論：三峽工程將永遠改變無數(shù)人的生活。

2. The ample evidence presented enables us to reasonably conclude that the scourge of AIDS will be brought under control in the foreseeable future .

提出的充分證據(jù)使我們能夠合理地得出這樣的結(jié)論：艾滋病的禍害在可預見的將來就能得到控制。

3. We must seek immediate solutions for problems leading to the rapid depletion of the earth's ozone layer. If allowed to proceed unchecked , the problem will undoubtedly exacerbate global warming and threaten life as we know it today .

我們必須尋求立即解決引起地球臭氧層快速損耗的問題的辦法。如果任其自由發(fā)展，這一問題無疑會加劇全球升溫，并且正如今天我們所知道的那樣危及生命。
