Lesson 16 A polite request
Part 1: Text
Discussion
1. Have you ever noticed the traffic signs in streets
2. Can you guess the meanings of the signs below
Text：
If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he let's you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car: ‘sir, we welcome you to out city. This is a “No Parking” area. You will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.’ If you receive a request like this, you cannot fail to obey it!

Part 4: Grammar
if引导的条件句
条件状语从句通常由连词if引导, 意为 “如果; 假如; 倘若”, 表示在某种条件下, 很可能会发生某种事情或不发生某种事情。
1
if条件状语从句的位置
在if引导的条件状语从句中, if条件句位置比较灵活,可放在主句前面也可放在主句后面。若放在主句前, 从句后面要用逗号和主句隔开。如:If he doesn't feel tired, he will visit the museum. = He will visit the museum if he doesn't feel tired. 如果他不感觉累, 他就去参观博物馆。
2
if条件状语从句的时态搭配
(1) 当主句用一般将来时, if引导的条件状语从句要用一般现在时。如:If it rains tomorrow, I won' t climb the hills. 如果明天下雨, 我就不爬山。(2) 当主句中含有can, may, must等情态动词时, if引导的条件状语从句要用一般现在时。如:
We can win the basketball game if he joins us. 如果他加入我们, 我们就能贏这场篮球赛。(3) 当主句是祈使句时, 引导的条件状语从句要用一般现在时。如:Help your mom with the housework if you finish your homework early. 如果你完成作业早, 就帮你妈妈做家务。
3
与其他句式之间的转换
(1) 借助“祈使句+and / or+ 一般将来时的句子”这一句型来转换。and在句意上表示顺承关系, or表示转折关系。如:If you get up early, you'll get there on time. = Get up early, and you'll get there on time. = Get up early, or you won't get there on time. 早点起床, 你就会准时到那里。(2) 借助介词without或with来转换条件状语从句。如:If there is no water, fish will die. = Fish will die without water.如果没有水, 鱼就会死。If you help me, I'll finish the work soon. = With your help, I'll finish the work soon. 如果你帮助我, 我就会快点完成工作。(3) if … not 导的条件状语从句, 可以借助连词unless来改写。如You will be late if you don't go there by bus. = You will be late unless you go there by bus. 如果你不乘公共汽车你就会迟到。
4
If “如果, 假如” 它引导的句子表示某事发生所需的条件，即“在…条件下，某事才能发生”，在句子中充当状语，因此称之为条件状语从句.
条件句中，将来时用现在是表示，即：主将从现
