三、阅读理解
Wildfire is one of the most powerful forces in nature. While North America's wildfire season typically peaks in late summer and early fall, climate change is already being blamed for a longer fire season.
When experts explain fire, they often talk about something called the "fire triangle": heat, fuel and oxygen. All three must interact for a fire to get started and to keep going. Take away any one of these and the fire is suppressed.
Heat is constantly coining out from a fire, warming the surrounding air and preheating fuel in its path. According to experts at the National Interagency Fire Centre heat allows fire to travel more easily by evapourating the moisture(水分) from nearby fuel. The temperature of these fuels can sometimes grow so high that they begin to burn even before they come into contact with flames.
Fuel is really just anything that can burn. That could mean both living and dead plants, coal and buildings. What's important to know here is that it's the moisture inside a fuel that determines how easily it will burn. Living trees have a lot of moisture. Dead trees have very little. But if a fire is really hot, the moisture content of a fuel means very little. In areas where the plants are dry, the temperature needed for burning is much lower.
For a fuel to burn, it needs to react with oxygen from the surrounding air so that it can release heat, which in turn helps the fire to spread. The air we breathe contains roughly 21 percent oxygen. Most fires require only 16 percent oxygen. Wildfire can change its supply if the oxygen level drops below 16 percent. Hot flames cause the air to heat up, and hot air will rise. Fresh air from a higher part of the sky then rushes in, providing the fire with new oxygen.
1.In North America, wildfire happens the most frequently in ________.
A.late spring B.early summer
C.late summer and early fall D.late winter
2.The underlined word "suppressed" in the second paragraph probably means "_______".
A.ended B.improved C.lit D.allowed

A.living plants can also catch fire easily in wildfire
B.coal is the most important fuel in wildfire
C.the moisture inside a fuel is hard to be driven out
D.in areas where the plants are dry the temperature is often low
4.What is the passage mainly about
A.The harm of wildfire. B.The science of wildfire.
C.How to prevent wildfire. D.Wildfire caused by climate change.

三、阅读理解
答案：1-4.CAAB
解析：语篇解读:野火经常会演变成旷日持久的大火灾,是什么让它难以被扑灭
1.解析:细节理解题。由第一段的North America's wildfire season typically peaks in late summer and early fall可知答案为C项。
2.解析:词义猜测题。前一句指出如果大火要开始和持续,那么有三个要素“必须”都具备,如果其中一个不存在了,那么大火就会熄灭。故A项正确。
3.解析:推理判断题。由第四段的信息"...it's the moisture inside a fuel that determines how easily it will burn. Living trees have a lot of moisture... But if a fire is really hot, the moisture content of a fuel means very little."可知A项正确。
4.解析:主旨大意题。文章主要介绍的是“火三角”中的三个要素是如何互相作用致使野火长久不灭的,研究的正是野火背后的科学知识,故选B项。
四、短文填空
答案：①when ②coming ③to escape ④complained ⑤but ⑥a ⑦that ⑧were found ⑨in ⑩Hopefully
解析：①考查定语从句。句意:那天早上8:16, 当这栋四层楼里的员工正在忙碌工作时, 有人看见浓烟从二层的窗户中冒了出来。这是一个定语从句, 先行词为8:16 that morning, 表示时间, 且从句缺少时间状语, 故填when。
②考查现在分词。句意同上。smoke与come之间是主动关系, 故填coming。
③考查非谓语动词。句意:火灾持续了将近一个小时, 345名员工中大多数人从火灾里逃了出来。manage to do sth.意为“设法做成某事”, 故填to escape。
④考查动词的时态。句意:一些员工抱怨救援来得太晚, 但是消防员的确在火势报道出来后的十分钟内就赶到了。文章使用的是一般过去时, 且由后面分句中的did也可知, 此处应使用一般过去时。故填complained。
⑤考查连词。句意同上。根据句意可知, 前后分句之间是转折关系, 故填but。
⑥考查冠词。句意:这栋大楼仅有的两个出口不足以让这么多人迅速撤出。in a hurry意为“迅速”, 为固定搭配。故填a。
⑦考查表语从句。句意:据调查者说, 起火原因是某个人违反了工厂的禁烟规定, 因为一些烟头被找到了。设空处位于was后, 且空后是一个完整的陈述句, 不缺句子成分, 所以这是一个表语从句, 故填that。
⑧考查动词的语态和时态。句意同上。全文使用的是一般过去时, 所以此处也应使用一般过去时。some cigarette ends与find之间是被动关系, 所以用被动语态。且some cigarette ends是名词的复数形式, 故填were found。
⑨考查固定搭配。句意:接下来的两周内, 会有15个检查组轮流在所有工厂工作, 以消除更多火灾发生的可能性。in turn意为“轮流, 依次”, 是固定搭配。故填in。
⑩考查副词。句意:希望这样的灾难不要再发生。 设空处位于句首, 修饰整个句子, 应用副词形式。故填Hopefully。
