托福口语高分句型–表示原因的用法
在托福独立口语Task 2中，通常会这样出题，Which one do you prefer, A or B? Do you agree or disagree with the following statement? 我们一看到这样的题型，肯定要做出选择，那为什么你选择A而不选择B呢，这里就要讲到原因了。

因此涉及原因的几种表达就显得很重要了。

最简单的就用because，because of好了。

例如:
I prefer to study in the library because the study environment is quite pleasant- bright and airy.
我喜欢在图书馆学习，因为那里的学习环境很好-明亮、通风。

I prefer to study in the library because of the brightness and airiness.
我喜欢在图书馆学习，因为那里明亮、通风。

用because，because of显然很直接，也很易用。

但是当你想表达多个原因，重复用because，就会显得你的词汇量和语法也太单调了。

下面我来介绍常用的以下几个。

第一个句型就是the reason (that/why)….is that…, that/why可省略。

例如：
The reason (that/why) I hate listening to heavy metal is that It really irritates me and drives me?crazy when the singers scream, jump up and down on the stage.
我不喜欢重金属音乐的原因是因为每当我看到那些歌手们在舞台上尖叫，蹦来蹦去时，我就烦躁，简直把我逼疯了。

第二句型就是since/seeing/considering + 从句，例如：
Nothing can stop the old people from receiving college education since having college degrees is their dreams.
没有什么能阻止老年人上大学，因为上大学就是他们的梦想。

Since we live in a global village, it’s beneficial to learn?a foreign language.
因为我们生活在一个地球村，学一门外语非常有益。

第二句型就是due to = owing to = thanks to = as a result of = on account of = because of, 等于号表明用法相同，后面都可接名词，动词的分词形式，但是意思稍有区别，都是表原因的意思，例如：
Due to my personality, I prefer to take a variety of courses.
由于我性格的原因，我更喜欢选择很多课程。

Taking a part time job is due to lack of money.
兼职是因为我缺钱。

It’s thanks to Lucy that my math has improved dramatically.
多亏了Lucy，我的数学提升很大。

It’s easy for me to get distracted as a result of the constant noise.
我很容易分神，因为外面闹声不断。

He doesn’t keep pets on account of the poor sanitary conditions caused by the pets.
他没有养宠物，因为宠物会导致卫生条件很差。

掌握好以上句型就显得丰富多了，但是要想灵活运用，需要大家多多练习。
