6.修改前：We know that sometimes success is measured by how much money you earn.

修改后：It does not surprise us to discover that sometimes success is measured in terms of the money you earn.

解析：

如上句的“believe”一樣，“know”也是非常初級(jí)的詞匯，作文中出現(xiàn)“I believe that…，I know that…”這樣的表達(dá)只能體現(xiàn)考生寫(xiě)作技巧的稚嫩，用“It does not surprise us to discover that…”替換“We know that…”并沒(méi)有改變?cè)涞暮x，卻使全句頓時(shí)增添了亮點(diǎn)。

7.修改前：We all know that most factories would be of no use if there were not clean water supply.

修改后：It goes without saying that most factories would be of no use if there were not clean water supply.

解析：

同上例一樣，“know”這樣的初級(jí)詞匯應(yīng)避免在作文中使用，It goes without saying that…是一個(gè)固定結(jié)構(gòu)，意思是“……是不言而喻的”，常在作文中用來(lái)引經(jīng)據(jù)典或表明一個(gè)盡人皆知的道理，類似的表達(dá)還有：

An old saying goes that…

Proverb goes that…

It is universally acknowledged that…

It is generally accepted that…

8.修改前：Some other people think that people should read extensively.

修改后：Another position says that people should read extensively.

解析：

同know，believe一樣，think也應(yīng)該盡量避免使用，修改后的句子中是用Another position says that…代替think提出另一種觀點(diǎn)，也可以用hold a point of view，hold the opinion這樣的短語(yǔ)替換。

9.修改前：The unexpected win of the match give us confidence.

修改后：The unexpected win of the match boost our confidence.

解析：

“give”也屬于英語(yǔ)中最初級(jí)、最基本的詞匯，只表示“給，給予”這個(gè)動(dòng)作，不涉及動(dòng)作的性質(zhì)和狀態(tài)，若表示增添信心，增強(qiáng)士氣，比較地道的說(shuō)法是用“boost confidence/morale”，如：The change of management has boosted morale throughout the company.管理模式的改變使整個(gè)公司上下士氣倍受鼓舞。

10.修改前：The use of drugs has increased greatly in the last ten years.

修改后：The use of drugs has increased significantly in the last ten years.

解析：

greatly是一般用語(yǔ)，表示程度高，“很，非常”，使用相當(dāng)普遍而沒(méi)有新意，在寫(xiě)作中應(yīng)盡量避免使用這些通俗而又陳舊的詞匯，應(yīng)換用一些更加正式，更有說(shuō)服力的詞語(yǔ)，例如significantly表示達(dá)到了非常重要的或可觀的程度，“重大的，可觀的”，能夠具體說(shuō)明藥品使用方面，增長(zhǎng)幅度巨大。significantly還可以替換成considerably，tremendously等，同樣具有不錯(cuò)的表達(dá)效果。

以上就是托福寫(xiě)作中詞匯使用的技巧，要想得到托福高分，單詞的多樣性和新鮮程度也是必不可少的，希望對(duì)大家有所幫助。
