2. 正确运用条件状语从句的技巧
(1)注意时态和语态的一致性:如果主句是一般现在时,那么条件状语从句通常使用一般现在时;如果主句是一般过去时,那么条件状语从句多使用过去完成时或过去将来时。
(2)注意虚拟语气的使用:在表达假设条件时,条件状语从句常常使用虚拟语气。例如:If I were you, I would study harder.(如果我是你,我会更加努力学习。)

高中必备知识点解析:让步状语从句与条件状语从句的区别
在高中英语学习中,从句是一个重要的知识点。而在从句中,让步状语从句和条件状语从句是两种常见的从句类型。它们虽然在句子中承担了不同的语法角色,但在用法上也存在一定的区别。本文将对让步状语从句与条件状语从句进行详细解析,并明确它们之间的区别。
一、让步状语从句
让步状语从句用来表示虽然某种情况存在,但是尽管如此,还是发生了另一个意外的情况。通常使用"although"、"though"、"even though"等来引导让步状语从句。让步状语从句一般位于主句之前或之后,用来修饰主句的谓语动词。
1. 引导词:
虽然让步状语从句的引导词有多种,但最常用的引导词是"although"、"though"和"even though"。这些引导词之间没有实质性的用法区别,只是在语气上有所不同。
2. 语序和动词时态:
让步状语从句的语序一般是陈述语序,即主语+谓语,而不是倒装语序。动词时态上,如果主句的谓语动词是一般现在时、一般将来时或祈使句时,让步状语从句中的谓语动词要使用一般现在时。而如果
主句的谓语动词是一般过去时,则让步状语从句中的谓语动词要使用
过去完成时。
举个例子:
1. Although it was raining, they still went hiking.
虽然下着雨,但他们还是去了远足。
2. Though he was tired, he continued working.
尽管他很累,但他仍然继续工作。
条件和让步状语从句
• provided/ providing (that)
• on condition that
但愿,要是…该多好
• as/so long as
• only if
只要,条件是 in case 万一,如果
• once
一旦
• If you want something done in a hurry, don’t go to the man who has clearly not much to do. • I shall return on Thursday unless something unexpected happens. • Suppose we can’t get the necessary data, what should we do? • We’ll let you use the room provided you keep it clean and tidy.
注意: •1. whoever, whatever, whichever等带ever的 词 可引导名词从句和让步状语从句。而 no matter who/ what/ which 等只能引导让步状 语从句
判断对错 No matter what you say is of no use now .
• if only 常引导虚拟条件句或感叹句, “但愿,要是…该多好” did/were 表现在 If only had done 表过去 would / might /could do 表将来

状语从句让步与条件
状语从句让步与条件
状语从句在英语中的使用非常广泛,其中让步状语从句和条件状语从句是最常见的两种。它们在句子中起到不同的作用,本文将重点讨论状语从句让步与条件的使用方法和语法特点。
一、让步状语从句
让步状语从句用于表示一种与主句中所表达的意思相反或相对的情况,即虽然主句发生某种情况,但还有其他情况存在。
让步状语从句的引导词有although(虽然)、though(尽管)、even if(即使)等。这些引导词后面的从句说明了一种让步的情况。
例如:
1. Although it was raining, he still went for a walk.(虽然下着雨,他仍然去散了个步。)
2. Though she is tired, she keeps working.(尽管她很累,但她仍然继续工作。)
3. Even if he fails the exam, he will try again.(即使他考试不及格,他还会再试一次。)
让步状语从句通常位于主句之前,但也可以将其置于主句之后,两者之间用逗号分隔。
二、条件状语从句
条件状语从句是用来表示一种条件与结果的关系,即只有满足某种条件,才能得到相应的结果。
条件状语从句的引导词有if(如果)、unless(除非)、provided/providing (that)(只要)、as long as(只要)等。从句中的谓语动词可以使用各种时态。
例如:
1. If it rains tomorrow, we'll stay at home.(如果明天下雨,我们就呆在家里。)
