托福獨(dú)立寫作主旨句在寫作中起著非常重要的作用，所以大家在練習(xí)托福獨(dú)立寫作的時(shí)候一定要了解如何才能寫出好的主旨句。下面小編就和大家分享托福獨(dú)立寫作主旨句怎么寫，來(lái)欣賞一下吧。

托福獨(dú)立寫作主旨句怎么寫?

一.獨(dú)立寫作主旨句寫作時(shí)有什么要求?

1.主旨句要寫的簡(jiǎn)短，不寫長(zhǎng)句。

這是因?yàn)橹髦季涫菍?duì)整段大意的概括，言簡(jiǎn)意賅，要求達(dá)到的目的是，當(dāng)考官讀完你的主旨句他就會(huì)了解你這段要寫什么。所以說(shuō)在這個(gè)領(lǐng)域，短句要比長(zhǎng)句效果更好，最多出現(xiàn)一個(gè)從句，盡量不要出現(xiàn)復(fù)雜句。

2.體現(xiàn)題目中的關(guān)鍵詞。

主旨句是概括本段的大意，那我們?cè)趯懙臅r(shí)候盡量把主旨句和整篇文章的題目做一下關(guān)聯(lián)，而最好的關(guān)聯(lián)方式呢，就是你重復(fù)一下題目當(dāng)中所出現(xiàn)的關(guān)鍵詞，告訴考官“我沒(méi)有跑題，我就是按照題目的要求寫的。”。

3.主旨句需要表達(dá)一個(gè)基本邏輯。

這個(gè)說(shuō)法有點(diǎn)空洞不好解釋，我來(lái)給大家舉個(gè)例子。

假使你的題目是“同不同意老師每天布置作業(yè)”，假設(shè)我要同意老師每天都布置作業(yè)，我是不是要找到每天布置作業(yè)的好處啊?

主旨句的基本邏輯就是這樣的，每天布置作業(yè)對(duì)學(xué)生來(lái)講有好處一，每天來(lái)講布置作業(yè)對(duì)學(xué)生有好處二。所以說(shuō)，這就構(gòu)成了一個(gè)基本的邏輯。我要寫清楚，為什么對(duì)學(xué)生有好處一，好處一是什么。

為什么對(duì)老師有好處二，好處二是什么，這就是一個(gè)基本的邏輯。讓考官能非常清楚的(明白)你這一段要展開的基本思路。

二.主旨句寫法實(shí)例講解

為大家準(zhǔn)備了充滿節(jié)日氣氛的禮物：

南瓜燈、萬(wàn)圣節(jié)面具、糖果、水彩筆、卡夾等

接下來(lái)我們用兩類題目來(lái)給大家講一講，主旨句寫作的時(shí)候有沒(méi)有什么固定的句型可以使用。

從大的方面來(lái)講呢，托福獨(dú)立寫作分為兩大類話題，一類叫利弊類，一類叫原因類。

利弊類主旨句寫法

什么是利弊類呢，就是通過(guò)找好處壞處能回答這個(gè)問(wèn)題。比如說(shuō)這個(gè)題目：

Do you agree or disagree with the following statement?

Students doing reading by their own personality is as important as, or more important than reading assigned by teachers.

學(xué)生按照自己的個(gè)性去選擇閱讀材料比老師布置閱讀材料更重要。假設(shè)我選擇不同意，我的觀點(diǎn)是，老師布置的閱讀更好，那是不是我要找到老師布置閱讀的基本好處啊?所以說(shuō)，這就叫做利弊類的話題。

回憶一下我們剛才說(shuō)的，題目當(dāng)中，主旨句要簡(jiǎn)短，要體現(xiàn)關(guān)鍵詞，也要體現(xiàn)基本邏輯。剛才我們把基本邏輯梳理了，那我們要找一找題目當(dāng)中的關(guān)鍵詞了，比如說(shuō)題目里邊的reading、assigned by teachers、personality像這些就屬于key words，要盡量在你的topic sentence里出現(xiàn)。比如說(shuō)我的主旨句可以寫成

第一個(gè)好處：

Reading assigned by teachers can help students to enlarge their range of knowledge.

老師布置作業(yè)可以幫助學(xué)生擴(kuò)展他們的知識(shí)面。

第二個(gè)好處：

Reading arranged by teachers could be beneficial for teachers to supervise the reading task.

老師安排閱讀對(duì)老師來(lái)講可以更好地去監(jiān)督閱讀任務(wù)的完成。

大家注意一下啊，這個(gè)里邊我用了兩個(gè)詞，一個(gè)是help，一個(gè)是be beneficial for，這兩個(gè)詞呢都可以表示“好處”，所以說(shuō)呢這類詞在寫利弊話題類的時(shí)候比較常用。

如果大家覺(jué)得這個(gè)句子是不是有點(diǎn)太簡(jiǎn)單，我想寫成一個(gè)復(fù)合句，當(dāng)然可以。大家注意看下邊這部分啊，這部分在講的就是用一個(gè)從句方式來(lái)表達(dá)這個(gè)觀點(diǎn)。既然是利弊類，我又說(shuō)的是好處，那很自然而然的我們就得出一個(gè)句型

The first advantage of reading assigned by teachers is that students would have a wider range of knowledge.

這個(gè)地方利用了The first advantage of sth is that...這個(gè)句式來(lái)非常清晰地告訴考官，老師布置作業(yè)的第一個(gè)好處是擴(kuò)大知識(shí)面。同理，那第二個(gè)topic sentence就可以利用同樣的句式來(lái)寫了。前邊是“The first advantage”，那第二個(gè)怎么寫呢，很容易，可以寫

Another advantage of reading assigned by teachers is that teachers could have better supervision on the reading tasks of students.

所以說(shuō)這兩個(gè)句式也可以比較固定化的表達(dá)，而這種表達(dá)也不會(huì)讓人認(rèn)為是模板。因?yàn)槲揖褪窍雽懞锰帲亲匀欢坏倪壿嬀褪堑谝粋€(gè)好處是什么，第二個(gè)好處是什么。所以說(shuō)這樣一寫利弊類的話題(主旨句的)句型，就基本上清晰了。

三.表達(dá)好處和壞處的主旨句句型

總結(jié)一下表達(dá)好處的基本句型：

你可以利用我們剛才第一組的topic sentence是用單句來(lái)說(shuō)的，你可以把題目當(dāng)中的話題變成一個(gè)doing的短語(yǔ)，再加上could be helpful、could be useful、could be beneficial for后邊加上好處的對(duì)象，再加上一個(gè)to do，加上一個(gè)具體的好處是什么，這就構(gòu)成了一個(gè)主旨句的基本句型。

如果你想用動(dòng)詞，我不想用helpful、useful這些形容詞，你可以使用contribute to或者使用我們剛才說(shuō)的那個(gè)help，都可以起到同樣表達(dá)“好處”的效果。

表達(dá)壞處的句型：

那表達(dá)“壞處”有什么句型呢，同理，把上邊那個(gè)句子稍微改一下就行了， 還需要把題目中的話題變成一個(gè)doing的短語(yǔ)，再加上could be harmful for、could be detrimental for、could be undesirable for加上壞處的對(duì)象，再加上to do，加上具體的壞處是什么就可以了。

如果你想使用動(dòng)詞的話，可以使用lead to或者使用cause，這兩個(gè)都可以表示產(chǎn)生不良的后果。如果你想用復(fù)合句型來(lái)表達(dá)好處壞處的話，上邊那個(gè)句型就可以用了。

The first advantage/disadvantage of后邊加上話題，加上is that...的從句，接上好處壞處是什么，就可以了。第二個(gè)topic sentence呢，Another advantage/disadvantage of加上話題，再加上is that...，再加上具體的好處或者壞處，這種復(fù)合型的主旨句也能寫出來(lái)了。

表達(dá)好處的基本句型有：

1、題目當(dāng)中的話題(doing)+could be helpful/useful/beneficial for +對(duì)象+to do具體的好處 …

2、contribute to

表達(dá)壞處的基本句型有：

1、題目當(dāng)中的話題(doing)+could be harmful/detrimental/undesirable for +對(duì)象+to do具體的壞處 …

2、lead to/cause

表達(dá)好處/壞處的復(fù)合句型有：

The first advantage/disadvantage of話題is that具體的好處/壞處

Another advantage/disadvantage of話題is that具體的好處/壞處

題目

The university will spend money on the dormitory to improve the life quality of students. Which of the following do you think is the best way?

1) Providing a room for quiet study

2) Building an exercise room

3) Providing entertainment place (watch film)

范文1：For Choice 2

If a university wants to improve the quality of life for the students, it should install an exercise room in each dormitory. Exercise balances out a quiet lifestyle based on studying(運(yùn)動(dòng)萬(wàn)能句). An exercise room could contain equipment that is impossible to keep in a dorm room, give students as safe place to work out, and provide an opportunity to meet people with the same interests.

分論點(diǎn)1：運(yùn)動(dòng)對(duì)學(xué)生很重要Exercise is essential for students, but often they neglect working out and focus only on studies. An exercise room in the dormitory would be easily accessible, so would encourage students to take a short break to keep their bodies fit. An exercise room could contain equipment such as weight benches and stationary bicycles(器械名稱積累) that are too big to keep in the individual dorm room or too expensive to buy or transport from home. An exercise room, therefore, would be a great investment for the university because it would provide the students with training facilities that they would not otherwise have access to without leaving the campus.

分論點(diǎn)2：保障學(xué)生安全A dormitory exercise room is also a wise idea because students would have a safe place to work out. The university could ensure that the equipment is clean and operating properly. On top of that, students would not have to leave the building to work out. Staying inside benefits the students in two ways. 原因1：避免路途中發(fā)生危險(xiǎn)First, they do not have to worry about walking alone, possibly late at night when classes are over. That way they do not have to risk trouble with strangers or people following them. 原因2：避免溫度變化引起生病Second, they are not exposed to a severe change in temperature. For example, working out in a warm place and stepping outside in the winter, a person can become sick. Such problems are prevented by staying in the same building.

分論點(diǎn)3：有助于社交Another reason to have an exercise room is to encourage students tointeract with each other(社交萬(wàn)能句). Students may find it fun to exercise together, urging each other on. Students who enjoy exercising can meet each other and become friends. If the students only exercise on their own, they may not realize that someone else has the same interests. Even if they live in the same dorm, they might not have the same classes, and therefore, not have any reason to speak to each other. A common bond of working out together could be formed if the university installed exercise rooms.

An exercise room allows students to work out on equipment they can’t bring from home in asafe environment with other students who enjoy the same activities. Therefore, adding an exercise room is a great investment for a university.

范文2：For Choice 3

To improve the quality of life of its students, our university should create an entertainment room in each dormitory building. An entertainment room would give students a chance to watch movies or attend activities that they otherwise could not, would allow students to make friends with the same interests, and would ensure a safe environment to relax.

分論點(diǎn)1：幫助學(xué)生省錢The stereotype of the “starving college student” may seem trite, but many students are on a tight budget and do not have excess cash for fun, extravagant activities(省錢萬(wàn)能句). Such students would greatly benefit from an entertainment room because they could, for example, watch movies without paying premium prices to go to a theater. They could enjoy a game of Ping-Pong without needing a car to drive to a community center with a Ping-Pong table. In other words, if each dormitory had its own activity room, students could enjoy a wide range of activities that they otherwise could not afford to do.

分論點(diǎn)2：有助于社交Furthermore, an entertainment room would encourage students to leave their dorm rooms and interact with a larger range of students. Instead of closeting themselves in a single room with an internet connection to the outside world, they can laugh and talk with others about the activities(社交萬(wàn)能句). Students with different majors or from different grade levels may not have classes in common, but in the activity room, they can find others with the same interests and eventually become friends(社交萬(wàn)能句). Therefore, an entertainment room would provide opportunities to increase social networks(社交萬(wàn)能句).

分論點(diǎn)3：保障學(xué)生安全Finally, college students often try risky or outright dangerous stuntsbecause they are living away from home for the first time. For example, they may drink a lot of alcohol and drive a car. In contrast, a dormitory entertainment room could provide safe activities. The room can be monitored so that there are no abuses of drugs or inappropriate behavior, allowing students to relax and enjoy themselves. In addition, if students get together regularly, they can easily observe negative changes in behavior such as a decline into depression(社交的好處、保護(hù)學(xué)生安全的萬(wàn)能句). Therefore, an entertainment room would give the students a chance to avoid dangerous activities and notice problems before they become serious.

In conclusion, our university should consider adding entertainment rooms in each dormitory. Such rooms can allow students to participate in fun activities and meet others in a safe and supportive environment.

題目

A government plans to spend money for all adults over 25-year-old to take a training course about the most up-to-date skills for the workplace. Do you think it is an effective plan? Why or why not?

參考范文

I think that it would be an effective use of money if the government paid for all adults over 25 years old to take training courses to update their work skills. Although such a program would involve certain expenses, the benefits for individuals and society would outweigh any negatives associated with a well-run continuing education program.

First, I want to qualify that such a program would be optional rather than mandatory. People who do not want to take classes would likely not pay attention or would avoid attending, wasting money that could be better spent elsewhere. Therefore, the program should be optional for anyone who is truly interested in improving skills. It is good for the government to offer such a program for all adults rather than to ones in certain fields or holding certain ranks. That way, the government ensures that everyone has a fair chance to develop without prejudice. For example, if only managers could participate, it might limit the average worker’s ability to advance to higher levels.

It is also important that the skills offered in the program are relevant to the individual’s career path and interests. Given such a program, adults could perform their duties better. They would be more efficient and productive. Companies would have a larger pool of trained workers to draw upon for all departments. Especially in this world of rapidly-changing technology and innovative new equipment and materials, it is important that workers learn the newest methods rather than stagnate. Workers with the latest knowledge in the field would be positioned to further development and increase production.

If production increases, the economy will prosper. Businesses can thrive as people make goods and services and earn salaries that allow them to buy those products, creating an upward spiral.

If all adults improve work skills, not only the marketing sector but also such areas as the arts and health-care sectors will improve. Lives will be enriched on all levels by better entertainment and better standards of living. The government benefits from increased income from taxes. At the same time, it has decreased expenses related to caring for the unemployed or sick.

By paying for adults to take training courses relevant to their jobs, the government creates a win-win situation in which the workers are able to find jobs and perform them efficiently. Productive companies lead to a strong economy that is able to support its own government. Therefore, governments should consider financing training courses for all adults.
