一個(gè)段落的主題思想靠推展句來(lái)實(shí)現(xiàn)，如果只有主題句而沒(méi)有推展句來(lái)進(jìn)一步交待和充實(shí)，就不能構(gòu)成一個(gè)完整的段落。同樣，雖然有推展句，但主題思想沒(méi)有得到相對(duì)圓滿的交待，給讀者一種意猶未盡的感覺(jué)。這樣的段落也不能完成其交際功能。例如：

Physical work can be a useful form of therapy for a mind in turmoil. Work concentrates your thoughts on a concrete task. Besides, it is more useful to work--you produce something rather than more anxiety or depression.

本段的主題句是段首句。本段的兩個(gè)推展句均不能回答主題句中提出的問(wèn)題。什么是“a mind in turmoil”Physical work又如何能改變這種情況?為什么它能起therapy的作用?讀者得不到明確的答案。

若要達(dá)到完整就必須盡可能地簡(jiǎn)明。例如：

It is not always true that a good picture is worth a thousand words. Often writing is much clearer than a picture. It is sometimes difficult to figure out what a picture means, but a careful writer can almost always explain it.

段首句所表達(dá)的主題思想是一種看法，必須有具體事例加以驗(yàn)證。上述兩個(gè)推展句只是在文字上對(duì)主題作些解釋，整個(gè)段落內(nèi)容空洞，簡(jiǎn)而不明。如果用一兩個(gè)具體的例子的話，就可以把主題解釋清楚了。比如下段：

It is not always true that a picture is worth a thousand words. Sometimes, pictures are pretty useless things. If you can't swim and fall in the river and start gulping water, will you be better off to hold up a picture of yourself drowning, or start screaming Help?

以上就是小編對(duì)如何保證雅思寫作完整性的整理介紹，希望對(duì)同學(xué)們的雅思考試有所幫助。同學(xué)們?cè)谘潘紓淇紩r(shí)多積累練習(xí)，才可以在雅思考試中運(yùn)用的得心應(yīng)手。小編預(yù)祝同學(xué)們?cè)谘潘伎荚囍腥〉煤玫某煽?jī)。
