在新托福口语考试中，要求考生的答案要清晰（clear）和连贯（coherent）。在紧张的、有严格时间限制的考试过程中要做到这两个要求，一个最为行之有效的方法便是使用逻辑感非常强烈的句型。本文将主要针对新托福口语Task3, 通过一些常见真题来探讨一下最能体现逻辑感的四大状语从句（即时间，原因，条件，让步）在考试当中的运用，从而帮助考生们有效展现清晰和连贯的语言能力。

一．四大条件状语从句

1 时间状语从句 【adverbial clause of time】：
Ø 常用引导词：When, while, as, after, before, as soon as, since, till

3 条件状语从句 【adverbial clause of condition】
Ø 常用引导词：if, unless,
Ø 特殊引导词：as/so long as, only if, providing/provided that, supposing that, in case that, on condition that
4 让步状语从句 【adverbial clause of concession】
Ø 常用引导词：though, although, even if, even though
Ø 特殊引导词： as（用在让步状语从句中必须要倒装），while（一般用在句首），no matter …, in spite of the fact that, while, whatever, whoever, wherever, whenever, however, whichever

二．Task 3真题示范讲解
例1：
Ø 题目简介：

Ø 回答演示1：

From the reading material, we know that the college is going to add music, dance and sculpture as compulsory courses. the man in the conversation thinks that this is a bad idea. First, he majors in banking and has to take finance class，he has to take the fine art courses, and he would lose some opportunities to choose the courses that he needs. Also, he points out that he doesn’t enjoy sculpture at all, it would help students relax, not everyone has the talent about arts. He has to take these courses, it will be a waste of time and make him stressful.

Ø 答案解析：
新托福口语part3中，通常需要考生将主要人物的态度以及两个理由清楚地表达出来，我们可以看到在这个范例中，虽然考生将reading part和listening part 中重要信息都涵盖在答案里，而且没有出现任何明显的语法错误，但是因为缺少必要的逻辑连接词，整个表达给我们一种非常凌乱的感觉，毫无任何连贯和清晰可言。这也是很多考生之所以虽然将笔记记得非常详细，却依然拿不到理想分数的主要原因。

From the reading material, we know that the college is going to add music, dance and sculpture as compulsory courses. However, the man in the conversation thinks that this is a bad idea, due to the following reasons. First, considering that he majors in banking and has to take finance class， he would lose some opportunities to choose the courses that he needs, if he had to take the fine art courses. Also, he points out that he doesn’t enjoy sculpture at all even though it would help students relax, for not everyone has the talent about arts. If he had to take these courses, it would be a waste of time and make him stressful.

Ø 答案解析：
在这个回答范例中，我们在原来答案的基础上加入了若干表示原因，让步，条件逻辑关系的连接词，构成了状语从句，可以很明显感到改动后的答案体现了强烈的逻辑感，前后句的关系更加紧密，语意立刻变得清晰，连贯。
