2．主語(yǔ)和謂語(yǔ)，名詞和代詞，以及人稱(chēng)是否保持一致
例 4 a) The eating habit of Chinese people have changed in the past decade.
b) The eating habit of Chinese people has changed in the past decade.
不管主語(yǔ)和謂語(yǔ)隔開(kāi)多遠(yuǎn)，主語(yǔ)當(dāng)中還有修飾成分，謂語(yǔ)要和真正的主語(yǔ)在數(shù)上保持一致。
例 5 a) Now fruits and vegetables can be seen everywhere when it is in season.
b) Now fruits and vegetables can be seen everywhere when they are in season.
例 6 a) I feel proud to come to our university.
b) I feel proud to come to this university
our和主語(yǔ) I不一致，或把 our改成 my，或改成 this。而這里用 this 較妥。
3．修飾語(yǔ)是否放在正確的位置上
例 7 a) Without television, people can't get information which comes from other parts of the world immediately.
b) Without television, people can't immediately get information which comes from other parts of the world.
a) 句子，immediately 顯然放錯(cuò)了位置。是“得到迅速?gòu)母鞯貍鱽?lái)的消息”，還是“迅速得到從各地傳來(lái)的消息”？意思含糊不清。
例 8 a) At the age of six, my father began to give me English lessons.
b) When I was five years old, my father began to give me English lessons.
a) 句子，At the age of six 放在這個(gè)位置上，變成了“我父親六歲的時(shí)候”。改變說(shuō)法，可以解決這個(gè)問(wèn)題。
例 9 a) To improve one's writing skill. regular practice is necessary.
b) To improve one's writing skill, one must make regular practice.
不定式短語(yǔ)的邏輯主語(yǔ)決不是regular practice，為了把邏輯關(guān)系表達(dá)清楚，要么把不定式短語(yǔ)改成If one wants to improve his writing skill，要么把主句改成one must make regular practice.
例 4 a) The eating habit of Chinese people have changed in the past decade.
