本题是含有if引导的条件状语从句的复合句。
在 if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。
选项的位置在 if 引导的条件状语从句中，要用一般现在时态，B C选项是将来时态不符合题意要排除。
D选项是现在完成时态不符合题意要排除。
Reach an agreement达成协议固定短语搭配。
agreement is reached协议做主语要用被动语态，故选A。
【点睛】if 条件句不一般,几个要点记心间;条件句,放在前,逗号要放句中间。
条件句表可能，主句多用将来时；条件句表事实，主句常用现在时。
在 if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。
如：We can walk there if we can't find a bus.If it rains tomorrow, we will not go to the zoo.What will you do if you find a panda in danger.如果 if 条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。
如： If bears are in danger, they attack people.注意：在 if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若 if 条件句放句首，从句后面要加逗号，和主句隔开。
还要注意前后时态一致原则。
9．----Mike wants to know if ________ a picnic tomorrow.---- Yes. But if it ________, we will visit the museum instead.A．you have; will rain B．you will have; will rainC．you will have; rains D．will you have; rains【答案】C【解析】试题分析：句意：--汤姆想知道明天你是否去野炊。
--是的，但是如果下雨的话，我们将改去参观博物馆。
if意为“是否”时，引导宾语从句，句中有tomorrow，用一般将来时态，第二空中if引导条件状语从句意为“假如”，主句用将来时从句用一般现在时表示将来，故选C 。
考点：考查动词的时态。
10．—Dave, let's start our training for the basketball game.—OK. We'll lose the game we try our best.A．unless B．if C．until D．since【答案】A【解析】【详解】句意：——戴夫，我们开始训练篮球比赛吧。
——好的。
除非我们尽力而为，否则我们会输掉比赛。
A. unless除非；B. if如果；C. until直到；D. since 自从。

因为weather为不可数名词，因此不用冠词。
A/C不对。
再因为中心词为名词，用such而不用so。
故选B。
点睛：such……that与so……that的区别：so……that和such……that的意思均为"如此……以致……"，都用来引导结果状语从句。
但二者用法不尽相同，现归納如下：so……that结构中的so为副词，后面跟形容词或副词；such…that中的such为形容词，后面接名词（名词前可以有形容词修饰）。
如：He became so angry that he couldn’t speak.他变得很生气，以致说不出话来。
12．_______it’s a public holiday today, some firefighters in our city are still on duty. A．Although B．Once C．If【答案】A【解析】【详解】句意“尽管今天是公共节假日，但是我们城市的一些消防员仍然在岗位值班”。

人教版初二状语从句练习50题含答案解析
人教版初二状语从句练习50题含答案解析1. I was reading a book ______ my mother came into my room.A. whenB. whileC. asD. since答案解析：A。
在时间状语从句中，when既可以表示一个时间点，也可以表示时间段，从句中的动词可以是短暂性动词也可以是延续性动词。
本题中“my mother came into my room”是短暂性动作，“when”符合语境。
while强调主句和从句的动作同时发生，从句中的动词必须是延续性动词，这里“came”是短暂性动词，所以B错误。
as表示两个动作同时进行，强调一边一边，在这里不太合适，C错误。
since表示自从，与本题语境不符，D错误。
2. ______ he got home, he started to do his homework.A. As soon asB. WhileC. BeforeD. After答案解析：A。
as soon as表示一就，他一到家就开始做作业，符合逻辑。
while强调动作同时进行，这里到家和做作业不是同时进行的，B错误。
before表示在之前，按照常理应该是到家后才做作业，C错误。
after虽然也有之后的意思，但as soon as更能体现动作的连贯性，D错误。
3. She didn't go to bed ______ she finished her homework.A. untilB. whileC. asD. if答案解析：A。
not...until...是固定搭配，表示直到才，她直到完成作业才去睡觉，这是正确的用法。
while强调同时进行，不符合题意，B错误。
as表示一边一边或者当的时候，C错误。
if表示如果，是条件状语从句的引导词，与本题时间状语从句不符，D错误。
4. ______ we were having dinner, the phone rang.A. WhileB. WhenC. AsD. Since答案解析：A。

考查固定结构辨析。
so/such…that是固定结构，表示“如此……以至于”，引导结果状语从句，可排除AD两项。
so修饰形容词或副词，such修饰名词或名词性短语。
本句beautiful（漂亮的）是形容词，需用so；根据句意结构和语境，可知选B。
