PETS三級寫作常為160-200個詞左右的短文，文章難易程度適中，對於文章的文體，語言等要求較高，考生在寫作時，要注意審請題目，抓住作文題目的核心重點，圍繞著題目展開寫作，考生在組織文章時要注意思路清晰，語言準確，句子完整，避免出現語法錯誤，另外，在寫作，要儘量運用連詞，如However，Nevertheless等，還要儘量運用諺語，如Every coin has two sides， More practice，more benefit，這樣會增加作文的寫作色彩，從而提高作文的得分。
作文考試的文體常分為四類:議論文;說明文;記敘文;描寫性作文。下面分別分析以上四類文章:
(一)議論文
議論文是作者就某個問題或事件發表自己看法的一種文體。作者旨在通過講事實、擺道理來說明自己的見解、主張，從而使人信服。寫議論文時要特別注意以下幾點:
①在段首就必須提出問題和作者的觀點，使讀者明確你的立場;②充分運用邏輯推理來說明自己的觀點，以理服人; ③說明材料(或論據)必須真實可靠，有說服力;④駁斥他人觀點時，應首先承認自己的觀點可能會有人反對，然後再去批駁他人的觀點，這樣才容易獲取他人的信任，使自己的觀點更加真實可靠、有說服力; ⑤結尾句進一步明白無誤地闡述自己的觀點，贏得讀者的贊同。
下面以一篇習作《如何解決交通擁擠問題》來看看這種文章的寫法。 ①為解決城市交通擁擠，有人建議建造更多的道路。②有的人則建議開闢更多的公共汽車線路。③我的建議。
How to Solve the Problem of Heavy Traffic?
With population rapidly increasing，heavy traffic has become a big headache for many cities. For this very reason，many government officials and experts have thought up some solutions，among which two draw much attention the country over.
Some people suggest that more and wider roads should be laid down. It is evident that it can relieve the traffic congestion in the streets，thus accelerating the flow of buses and cars. And meanwhile， the fast and smooth flow of traffic reduces the air pollution caused by engine-idling. But the disadvantage of this solution lies in the fact that too much land that could be used for farming or housing will inevitably be occupied by more and more roads. Therefore，others hold that the number of public bus routes should be raised so that more people can be transported and fewer people will have to travel in their own cars or ride bikes. Less use of bicycles and private cars will make the roads less crowded. Unfortunately，there is also a drawback in this solution; it will bring inconvenience to those who live or work far away from bus stops.
As neither of the two solutions is effective enough to solve the problem of heavy traffic in cities，I favor a combination of the two. While building more roads in places where land is less useful，we should increase the number of public bus lines. Only in this way can we more efficiently solve the problem of heavy traffic.
【譯文】如何解決交通擁擠的問題
隨著人口的迅速增長，交通擁擠已成為許多城市難以解決的問題。正是由於這種原因，許多政府官員以及專家提出了一些解決方案，其中有兩個引起了全國的'極大關注。
有人建議建造更多更寬的道路。很明顯，這樣會緩解道路交通的擁擠，從而加快車速。同時，快速而又流暢的車輛還會減少由發動機變速導致的空氣汙染。但此種方案的不足之處在於這樣一個事實;建造道路會不可避免地佔用過多的土地，而這些土地本來是可以用於耕作或建房的。故此，另一些人主張開闢更多的公共汽車線路，使更多的人不去駕車或騎車，而是讓他們去乘坐公交汽車。這樣一來，也可以降低道路擁擠。不幸的是，它也有缺陷，即給那些遠離公共汽車站的人的生活和工作帶來不便。
由於這兩種解決方案都不能有效地解決城市交通擁擠問題，我贊成採取將兩者結合起來的方法。一方面在土地不緊張的地方建造更多的道路，另一方面增加公共汽車線路。只有用這種方法，我們才能更有效地解決交通擁擠問題。當然，我們也可以運用作文模式來寫議論文。
