should 意為“應(yīng)該”，否定式是 shouldn't“不應(yīng)該”

Our world in danger
Thanks to Earth, we have fresh air to breathe, clean water to drink and warm sunshine to enjoy. But it seems that we may have considered those things natural and haven’t realized that our planet is getting “sick”. Now scientists have given us a warning.
More than 15,000 scientists around the world have written a letter to warn about environmental threats (威脅), the Washington Post reported.
Among those environmental challenges, climate change sits at the top. Global average temperatures have risen by more than 0.5℃since 1992. A half-degree temperature rise is a big deal. It means that heat waves would last around a third longer and rainstorms would be about a third more intense (猛烈的). The increase in sea levels would be much higher, according to NASA．Countries like Singapore and Tokyo that are at low altitudes (海拔) may be covered by the ocean in the future.
But this is not the only problem people are facing. It’s getting harder to get fresh water. Ocean pollution has become serious. Since 1992, the human population has grown by 2 billion, while the populations of all other animals have dropped by nearly 30 percent.
Scientists say that we are experiencing the sixth mass extinction (物種大滅絕) in history. More than two-thirds of the world’s wildlife could be gone by the end of the decade if action isn’t taken soon, according to the World Wildlife Fund. The Amur leopard (遠東豹), black rhino and cross river gorilla (克羅斯河大猩猩) are some of the most endangered animals.
However, we have made some progress by making the hole in the ozone layer (臭氧層) smaller. That’s because we gradually stopped using chemicals that can break down ozone.
This progress shows that we can make positive changes when we act decisively, the letter says.
36．What does the underlined word “warn” mean
A．建議 B．宣布 C．打擊 D．警告
37．Global average temperatures have risen by________ since 1992.
A．more than 0.1℃ B．less than 0.5℃
C．more than 0.5℃ D．more than 5℃
38．A half-degree temperature rise is________.
A．not a big problem B．good news for people
C．a(chǎn) bad thing D．a(chǎn) usual thing
39．Since 1992, the human population has grown while the populations of all other animals have________.
A．reduced B．grown C．increased D．not changed
40．The purpose of this passage is to________.
A．tell people the current state of the Earth
B．call on people to protect the environment
C．display letters written by scientists
D．introduce climate change
五、短文填空
閱讀下面短文，在空白處填入一個適當?shù)脑~，或填入括號中所給單詞的正確形式。

參考答案：
1．a(chǎn)re planted
【詳解】句意：每年在山上種上許多樹。分析句子結(jié)構(gòu)可知，主語“Lots of trees”與動詞plant“種植”為被動關(guān)系，應(yīng)用被動語態(tài)；且根據(jù)“every year”可知，句子時態(tài)為一般現(xiàn)在時，因此這里應(yīng)用一般現(xiàn)在時的被動語態(tài)，其結(jié)構(gòu)為is/are/am done；主語“Lots of trees”為第三人稱復(fù)數(shù)，be動詞用are，動詞plant的過去分詞為planted。故填are planted。
2．ugliest
【詳解】句意：——這是我見過的最丑的建筑?！也煌?。我認為它很特別。ugly “丑陋的”，是形容詞，根據(jù)“I have ever seen”以及空前定冠詞the可知，此處應(yīng)用形容詞最高級形式，故填ugliest。
3．difference
【詳解】句意：這只是一件小事，但它確實對環(huán)境產(chǎn)生了影響。make a difference“有影響”，故填difference。

5．thankfully

6．methods

7．a(chǎn)fforded
【解析】略
8．is dividing
【詳解】句意：看！琳達正在把蘋果分成三份。根據(jù)“Look!”可知，強調(diào)動作正在發(fā)生，用現(xiàn)在進行時，故填is dividing。
9．locked
【詳解】句意：被關(guān)在動物園里的動物不會感到快樂。根據(jù)“Animals”和“l(fā)ock”可知，此處是定語從句，兩者之間存在被動關(guān)系，結(jié)構(gòu)為be+done，lock的過去分詞是locked。故填locked。
10．harmful
【詳解】句意：吸煙有害健康，所以請告訴你父親戒煙。根據(jù)“so please tell your father to give it up”及常識可知，吸煙有害健康，be harmful to…“對……有害”，固定詞組。故填harmful。
11．B
