...The purpose of our study is to consider several methodological issues relevant for study of the monetary transmission process. These issues involve relative emphasis on monetary shocks as opposed to systematic policy adjustments; vector autoregression vs. Structural modelling research strategies...
这里as opposed to等同于vs.（versus的缩写形式），为了避免重复，作者用了同义表达的技巧。
The appearance of cars has caused many social problems. What is your opinion?
...I believe cars have indeed caused many problems in society and we need to reduce the use of cars.
First of all, we must consider the severe traffic caused by cars...
Another consideration is that cars generate serious pollution...
Admittedly, cars facilitate our travel and make people’s daily commute much easier than before. However, the adverse effects of cars significantly outweigh the benefits they bring.
Any government, whether rich or poor, cannot put every penny into education, even though it may be trying to improve overall conditions for education and to create much needed rewards for teachers. Private schools, on the other hand, help to narrow government spending on education by charging wealthy students expensive tuition fees in return for superior learning facilities and highly sought after staff. That is why governments throughout the world, whether developed or developing, encourage individuals and enterprises to establish private schools. The Chinese government has even put forward an incentive to support any interested parties, both in China and from overseas, to help promote and expand existing private education across the country.
Firstly, modern people suffer from greater tension so that they have less time to communicate with each other. More and more people are living in urban areas, where life has a quick rhythm. Due to fierce competition, city dwellers have to be hard-working in order to keep up with the pace of city life. Everybody is busy all the time and the other increasing pressures at work deprive us of a casual way of life. Moreover, living in apartments in isolated blocks, we are becoming more and more removed from each other. And more often than not, it is no longer convenient for us to meet one anther freely.
tensions表达了和pressures完全相同的意思，但是这样写不会显得单调重复；划线部分也是一种巧妙的同义改写形式：have less time to communicate with each other意思就是becoming more and more removed from each other，但是用了同义转换立即给文章增添了色彩！
Activities in environments that pose great danger to humans, such as locating sunken ships, cleanup of nuclear waste, prospecting for underwater mineral deposits, and active volcano exploration, are ideally suited to robots. Similarly, robots can explore distant planets. NASA’s Galileo, an unpiloted space probe, travelled to Jupiter in 1996 and performed tasks such as determining the chemical content of the atmosphere there.
古人讲究“行云流水击节而歌，杏花巷里沽酒饯行”。只有行文如流水，写出的文章才能彰显流畅。而英文写作要求的不是那种委婉，要求思路清晰，文章脉络一目了然，讲究的是很强的逻辑性。这些特点在学术性雅思作文中显得尤为突出，这就要求我们能遵循简洁而不是简单（concise but not simple）并有逻辑的布局谋篇。
Avoiding pollution can be a full-time job. Try not to inhale traffic fumes; keep away from chemical plants and building-sites; wear a mask when cycling. It is enough to make you want to stay at home. But that, according to a growing body of scientific evidence, would also be a bad idea. Research shows that levels of pollutants such as hazardous gases, particulate matter and other chemical “nasties” are usually higher indoors than out, even in the most polluted cities. Since the average American spends 18 hours indoors for every hour outside, it looks as though many environmentalists may be attacking the wrong target.
这段话句陈述一个论断，紧接着用三个并列的动作（动词短语来实现）加以阐释。接着用指代词“it”衔接前文提到的内容，而后用转折连词“but”做一个小转折，最后用一个 “since”呈现出一个因果关系（Since the average American spends 18 hours indoors for every hour outside, it looks as though many environmentalists may be attacking the wrong target.）。整段文章非常紧凑，搭配合理，衔接自然紧密，逻辑清晰，用词多变，是具有代表性的优秀段落。这就是我们要达到的理想雅思作文。如果考生还有什么疑问，可以在线咨询我们的老师。
