很多同学在进行托福写作备考时都发现自己欠缺一些固定的句型结构。小编特意收集了一套TOEFL写作必备结构供大家学习。
assign homework to sb. 为某人布置作业
Mr. Thompson is not very popular,because he always assigns too much homework to his students.
在国外，老师留的作业既可以叫作homework，也可以叫作assignment。很多学生会说“I have a huge assignment to do this weekend.”我这个周末有一个很大的功课要做。
be/get involved in outdoor activities 参与户外活动
Many boys like to do sports and they enjoy getting involved in outdoor activities.
国外的学校会组织很多的outdoor activities/户外活动。这类活动一般包括：参观博物馆/visit the museum、做志愿者/do voluntary work、体育活动/sport games/physical activity等。
career preparation 职业准备
People attend college or university for many reasons,for example career preparation.
很多大学都会给学生进入职场前，进行一些准备工作，通常叫作career preparation。学校的职业指导中心/career centre会给你很多相关的建议，例如如何准备面试/how to prepare for an interview、如何与同事沟通/how to communicate with your colleagues、如何高效地工作/how to work efficiently等。
develop expertisein… 培养在......方面的专长
Mary dreams to be a great nurse,so she tries very hard to develop her expertise in nursing.
Expertise来自于我们很熟悉的一个单词expert/专家。Expertise是指你在某一领域的专长。Develop expertise in 后面一定要加名词，如果是动词的话，一定要记得加上ing变成动名词的形式。
expand one's knowledge 拓展知识
The best way to expand your knowledge is to read books in the library.
在这个短语里，我们除了可以使用expand之外，还可以使用increase。但是increase出现的频率实在是太高了，所以想得高分的同学不妨使用expand，毕竟“物以稀为贵”嘛。
extracurricular activities 课外活动
Students who are active in various extracurricular activities show some great abilities such as leadership and managements skills.
课外活动叫做extracurricular activities。Extracurricular是一个形容词，意思是“课外的”。我们也可以使用extra curriculum来进行代替，两个词组表达的含义是一样的。
feel peer pressure 感到来自同龄人的压力
Some students who can not fit in may feel some peer pressure.
Peer在英语里的意思是“同辈，同事，同龄人;同等地位的人”。而peer pressure可以指来自周遭的人的压力。例如，别人都有了女朋友或男朋友，而你还是孤身一人，那么你就可能会感受到peer pressure。
form a study group 组成学习小组
If you liked is cussions and group works,you can form a study group with others.
对于留学生来讲，学校老师会经常布置很多小组作业/team work/assignment。这就要求你和其他的几个学生组成学习小组。我们除了可以使用form来表达“成立、组成”的含义之外，还可以使用build，那么整个词组就会变成build a study group。
get a good grade 取得好成绩
Mrs. Black is a very strict professor. It is almost impossible to get an “A” in the exam. So students work very hard to get a good grade.
在国外，成绩除了叫作score以外，还可以叫作grade。Grade是一个多义词，除了有年级的意思之外，还有成绩的意思。所以大家一定要注意积累。
learn by doing 通过......学习
If you choose chemistry as your major, you will learn a lot by doing experiments.
外国学生的学习方式多种多样，不仅仅是在课堂上听老师讲课，还有其他的学习方式，例如拓展阅读/reading extensively、野外观察/having a field trip、观看纪录片/watching a documentary等。
pursue one's individual interest 追求个人兴趣
There are many activities and clubs in our school;it gives us a great chance to pursue our individual interests.
在这个句子里，个人兴趣可以说成individual interest，也可以说成personal interest。类似的词组有：追求梦想/pursue/chase one’s dream、完全实现自己的抱负/fulfill oneself等。
with the help of … 在......的帮助下
With the help of the career center,many students can find their ideal job after graduation.
我们有很多类似的短语，例如with the guidance of …/在某人的指引下，with the permission of …/在征得某人的许可后等。
总之，写作的提高有很多因素，我们希望文章可以为大家补充实用词组，从而帮助大家在TOEFL考试中取得满意的分数。
