一篇好文章的條件很多。除了內(nèi)容豐富和組織緊密之外，詞匯的運(yùn)用和句子的處理，也起著決定性作用。句子可長(zhǎng)可短，同一件事，可以用不同的句式表達(dá)。如果句子清一色是簡(jiǎn)單句，文章必定很單調(diào)乏味。如果全篇充滿了冗長(zhǎng)的復(fù)雜句，讀起來也很費(fèi)力。
　　最好的方法是以簡(jiǎn)單句為基礎(chǔ)，配合適當(dāng)?shù)牟⒘芯浜蛷?fù)雜句。簡(jiǎn)單句可長(zhǎng)可短，通常要加些附屬成分，如分詞短語、介詞短語、副詞短語、不定式動(dòng)詞短語，以及節(jié)縮成分。總之，作者可根據(jù)情況，使句子多樣化，使文章靈活多姿。例如下列五個(gè)句子的基本概念一樣，但是句式不同，內(nèi)容重點(diǎn)也有些差別：
　　(1) The goats grazed peacefully in the farm and were unaware of the approaching hunter. (并列分句(1)+2)
　　(2) Grazing peacefully, the goats in the farm were unaware of the approaching hunter. (現(xiàn)在分語短語+簡(jiǎn)單句)
　　(3) In the farm, the goats grazed peacefully and were unaware of the approaching hunter. (副詞短語+并列分句(1)-(2) )
　　(4) There were goats grazing peacefully in the farm, unaware of the approaching hunter. (簡(jiǎn)單句+形容語短語)
　　(5) As the goats grazed peacefully in the farm, they were unaware of the approaching hunter. (原因副詞從句+主句)
　　(1)和(5)的句式最常見；如果加上其他三種互相交替，句子不是更多樣化嗎？最后，看看這兩個(gè)句子要如何多樣化呢？
　　(6) The young pilot was on his first overseas training.
　　(7) He felt very uneasy.
　　(a) The young pilot on his first overseas training felt very uneasy.
　　(b) The young pilot felt very uneasy during his first overseas training.
　　(c) The young pilot's first overseas training made him feel very uneasy.
　　(d) Extreme uneasiness seized the young pilot on his first overseas training.
　　(e) The young pilot was on his first overseas training, feeling very uneasy.
　　(f) It being his first overseas training, the young pilot felt very uneasy.
　　(g) Being on his first overseas training, the young pilot felt very uneasy.
　　(h) The young pilot was on his first overseas training and felt very uneasy.
　　(i) The young pilot, who was on his first overseas training, felt very uneasy.
　　(j) When the young pilot was on his/first overseas trainging, he felt very uneasy.
　　(k) As the young pilot was on his first overseas training, he felt very uneasy.
　　(l) The young pilot was on his first overseas training, so that he felt very uneasy.
　　在上述12個(gè)句子中，(a)-(g)是簡(jiǎn)單句；(h)是并列句；(i)-(l)是復(fù)雜句。簡(jiǎn)單句除(b)和(g)之外，其他五樣，用的人并不多。人們最喜歡采用復(fù)雜句，尤其是(j)和(k)這兩款；接著便是并列句(h)。如果大多數(shù)人的句子只限于(b),(g), (h), (j)和(k)這五種，而其他的則棄如敝屣，不是很可惜。
