托福寫作病句的改造

　　所謂破碎句，就是句子不完整，通常是沒(méi)有謂語(yǔ)(或者說(shuō)謂語(yǔ)是動(dòng)詞的非謂語(yǔ)形式，如分詞)，或者是從句單獨(dú)成句。

　　破碎句：She singing alone. (無(wú)謂語(yǔ)，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(dú)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(gè)句子直接連在一起，既未使用連詞，也未使用正確的標(biāo)點(diǎn)符號(hào)。

　　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(gè)獨(dú)立的句子之間以逗號(hào)連接，這是不合英語(yǔ)語(yǔ)法的。正確的做法是以連詞、分號(hào)、冒號(hào)、句號(hào)等連接兩個(gè)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.
