托福寫作怎么運用情態(tài)動詞

首先是情態(tài)動詞，尤其是Will的漏掉。中國考生受漢語影響，一提到“將來”才會有意識地用will，實際上will可以表達“能、將、會、要、就”等多種意義。只是涉及到這樣的地方很多學(xué)員就把這幾個詞當作虛詞忽略掉了，以至于經(jīng)常出現(xiàn)“觀點”與“事實”不分的句子, 如：

Riding bicycles reduces air pollution.

如果沒有情態(tài)動詞，這個句子就是一個表示目前存在的狀態(tài)或者事實，而不表示個人對騎自行車的評價。

其它的常見的漏用還體現(xiàn)在與if引導(dǎo)的狀語從句一起連用的主句中，so that或者 in order that引導(dǎo)的從句，或者是與without, in case of等介詞短語連用的主句， 不論條件還是目的都是寫作中經(jīng)常出現(xiàn)的句式。如：

If I have time tomorrow, I drive to pick you up.

Xiao Zhang gets up very early so that he catches the earliest bus to work.

Without enough time to stay inside campus, college students don't have time to improve themselves.

其次是情態(tài)動詞的誤用，主要問題是中國學(xué)生在亮觀點時對“can”情有獨鐘，而英式的學(xué)風(fēng)歷來講究嚴謹，像can 這樣語氣過于絕對的表達最好換成may/ will，或者是語氣更委婉的might/would probably等，同時還要搭配一定程度的副詞，如：

indulgence in computer games can lead to social violence especially of teenagers。上句中can不如might用起來更加客觀，因為幾乎每個小孩都玩游戲，但絕不是每個人都會犯罪。

另外一個容易誤用的詞是should，多表示根據(jù)社會風(fēng)俗習(xí)慣個人的責(zé)任，而在比較正式的議論文寫作中，多數(shù)句子是以客觀事物做主語的，所以用should就有些不太恰當，如：

To tackle the problem of youth crimes related with computer games, advertisement enterprises should restrict the large-scale promotion.

一般我們會用另外一個更客觀性的短語be to do來代替，或者是shall，但是這里的shall不是用于第一人稱后的將來時符號，而表示的是一種情態(tài)。

至于must，因為語氣實在強硬，所以一般在社會性的問題的論述上我們要慎用，建議多換成need/ shall/ be to do 或者是be expected to do形式。如：

To help students get better employment, universities must increase the skillful courses.

托福寫作難點話題一覽

Does a zoo have no useful purpose?

Do you agree or disagree with the following statement? A zoo has no useful purpose. Use specific reasons and examples to explain your answer.

寫作思路展開結(jié)構(gòu)分析

不能同意，no是絕對修飾詞，因此一旦出現(xiàn)肯定是要否定的。至于公園的useful purpose有很多，大家可以任選幾條來展開，當然由于現(xiàn)在有許多公園因為經(jīng)費不夠而虐待動物的新聞報道，因此大家也可以舉例后指出確實有一些動物園不值得保留下去。

Perhaps one of the most blameworthy factors that make some people raise the eyebrow to zoos and criticize that "A zoo has no useful purpose" is its exorbitant price to maintain. However, it is too hasty to say so, since most zoos have their significance, both educational and scientific. Modern zoos act as centers of education and are designed to make learning about animals an interesting and enjoyable experience. They provide visitors with the chance to see rare creatures, such as tigers, zebras, penguins, and giant pandas, which come from many different parts of the globe. Zoos also introduce people to their own local wildlife, offering a valuable learning experience in an increasingly urban world. At the same time, most zoos provide educational programs aimed at a wide range of ages. A visit to a zoo provides children an opportunity to see and touch animals other than household pets. For older schoolchildren, many zoos conduct classes or day trips that focus on different aspects of animal biology and the impact of humans on animal life.

Modern zoos also have their scientific imports and can function as a sanctuary for endangered animals and therefore help maintaining ecosystems. In zoos scientists can create an animal population that can become self-sustaining in the wild. An example of a successful reintroduction to the wild is the David's deer. This Asian deer was native to marshlands in northeast China before its habitat was destroyed more than 800 years ago and it became extinct in the wild. Since that time the species has been bred in zoos in China and later in Europe. In 1985 four David's deer were released to the wild in a protected animal reserve in China, where they are now breeding successfully.

On the other hand, some experts warn against placing too much reliance on zoos as biological "arks," where species can be protected regardless of environmental changes outside. Critics warn that zoos, like all human institutions, are vulnerable to unforeseen events, such as disease, fires, and financial or social upheaval. More significantly, the number of species that zoos can protect is strictly limited. Today's zoos are home to no more than a few thousand species—only a fraction of the world's animal life. Zoos already have to perform a delicate balancing act between large, crowd-attracting animals and threatened animals that have less visitor appeal. During the 21st century, zoo experts will face even harder decisions about which species they can afford to save.

托福寫作難點話題一覽

Is banning smoking in public places a good rule or a bad rule?

In some countries, people are no longer allowed to smoke in many public places and office buildings. Do you think this is a good rule or a bad rule? Use specific reasons and details to support your position.

寫作思路展開結(jié)構(gòu)分析

當然是好規(guī)矩。公眾場所吸煙本來就是違規(guī)甚至在一些地方違法的行為。大家要注意要展開的不只是吸煙的害處，更需要說明在公共場合吸煙的害處，比如對不吸煙的人有害/可能引起火災(zāi)等等。

In spite of all of the known dangers of smoking, people all over the world continue to indulge in this terrible habit. By allowing people to partake in a cigarette whenever they please, the government is encouraging the smokers' early death. Smoking should be made illegal in all public places as it is very dangerous to one's health, it endangers the life of people who must work in smoky environments, and it makes it difficult for smokers to cut down on their nicotine intake, as they can smoke everywhere. As mentioned above, there are a vast number of illnesses caused by cigarette smoke. The major disease caused by smoking is lung cancer. This particular type of cancer alone kills more people each year than any other illness.

Not only is it associated with lung cancer, it is also associated with heart disease, birth defects and a host of other disorders. On a more aesthetic level, smoking yellows one's teeth and hands, which makes him unattractive. Most people also find the smell of a smoker to be undesirable. It is not only the smoker himself who is injured by his habit. People who must work in smoky environments, such as barmaids and waiters, are susceptible to all of the above-mentioned ailments. Also, the children and spouse of a smoker will be affected by the constant smoke in their environment, and will also be adversely affected. It is unfair for people to suffer for other's bad habits. If one could only smoke in the privacy of one's home, many lives would be saved.

Finally, it is important to disallow smokers to smoke in public because doing so increases their likelihood of smoking often. If a person must go into a private area to smoke, they would be less likely to do so. It is an inconvenience, and the smoker would therefore partake in a cigarette less often. In many places in the world, it is very cold in the winter. If a person had to smoke outside in these conditions, they would be far less likely to do so. This would eventually make it easier for the smoker to quit the habit. Therefore, I believe that it would be beneficial for everyone if smokers were only allowed to have a cigarette while in private smoking areas. Enforcing this rule would save thousands of lives, and would also decrease the amount spent on health care dramatically.
