一遍又一遍地重復(fù)句式相同、長度相似的句子會使一段話變得枯燥無味。比如：

    We have received your letter of April 2.We are sorry for the wrong dispatch We will do something about it.

    為了避免以上情況的發(fā)生，最好使句子結(jié)構(gòu)變化多端，可通過以下方法使句子發(fā)生變化。

(1) 改變句子長度。在一段文字中運用長短句交叉，可使句子變得錯落有致。試比較：

    We have received your letter of 2nd July.We regret that travellers cheques are not acceptable.Please give us instructions to make a transfer.

    Thank you for your letter of July 2.We are afraid that the suppliers may not accept travellers cheques for payment.Please give us instructions to make a transfer.

(2) 改變句子結(jié)構(gòu)，以不同的方式來造句。

    Despite our sales increase,profits fell.

    Consequently,the prices came down.

    To reach overseas markets,we must find better means of distribution.

(3) 改變句子的動勢。不要總按照主語——謂語（動詞）——補語的順序造句。試比較：

    I have received your letter of April 10.I shall be arriving in Brussels on May 2. I must return immediately after the meeting. I cannot therefore accept your invitation to dinner that evening.

    Thank you for your letter of April 10. I shall be arriving in Brussels on May 2. Unfortunately, I must return immediately after the meeting, and therefore cannot accept your invitation to dinner that evening.
