一遍又一遍地重復(fù)句式相同、長(zhǎng)度相似的句子會(huì)使一段話變得枯燥無(wú)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(guò)以下方法使句子發(fā)生變化。

(1) 改變句子長(zhǎng)度。在一段文字中運(yùn)用長(zhǎng)短句交叉，可使句子變得錯(cuò)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(lái)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(dòng)勢(shì)。不要總按照主語(yǔ)——謂語(yǔ)（動(dòng)詞）——補(bǔ)語(yǔ)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.
