《2026年高中必刷题高二下英语人教版》

阅读下面短文，在空白处填入 1 个适当的单词或括号内单词的正确形式。
The ocean and atmosphere are getting warmer. Ice is melting and sea levels are rising, 1which is a phenomenon called global warming. Global warming refers to an average increase in the Earth's temperature that has an impact 2on/upon Earth's ecology.
Climate scientists subscribe to the view that it is the “man - made” greenhouse effect that has caused global warming. When people burn fossil fuels, more heat energy 3is trapped (trap) in the atmosphere and causes Earth's surface temperature to rise quickly.
4Evidence (evident) shows that the rise in temperature has resulted in extreme weather and natural disasters worldwide. Not only have they caused serious damage, but they 5have cost (cost) humans their lives. If we don't take appropriate measures, this trend will 6probably (probable) continue and there will be a higher price to pay.
Global warming is a big problem. 7To solve (solve) the problem requires the world's attention. Governments should make 8a variety of practical 9policies (policy) to reduce greenhouse gas emissions. We need to restrict the amount of carbon dioxide our lifestyles produce. Also, it's important to educate everyone about global warming. Small changes 10made (make) by everyone could be the changes that save our future.

答案： 1 which is a phenomenon called global warming 是非限制性定语从句，关系词在定语从句中作主语，指代前面主句内容，所以应用关系代词 which 引导该从句。
2 on/upon have an impact on/upon... 为固定搭配，意为“对……有影响”。故填 on/upon。
上分点：表示“对……有影响”的短语有 have an effect/impact/influence on/upon...。
3 is trapped 设空处与 causes 并列作主句的谓语，时态应保持一致，且 trap 与主句主语之间是被动关系，所以此处应用一般现在时的被动语态；主句主语为 more heat energy，energy 意为“能量；能源”时为不可数名词，所以助动词应用 is，故填 is trapped。
4 Evidence 设空处作主句主语，应用名词，evidence 为不可数名词，且设空处位于句首。故填 Evidence。
5 have cost 设空处为并列分句的谓语动词，根据前面的 have they caused 可知，此处应用现在完成时。结合主语 they 可知，助动词用 have。故填 have cost。

6 probably 设空处修饰动词 continue，应用副词。
7 To solve 此处表示具体的动作，且表示将来含义，应用不定式作主语。
8 a a variety of 意为“多种多样的；各不相同的”。
9 policies policy 表示“（针对某一问题的或某国的）政策”时可作可数名词，此处指“各种实用的政策”，所以应用复数形式。故填 policies。
10 made 此处作定语，应用动词的非谓语形式，make 与 Small changes 之间是逻辑上的被动关系，所以应用过去分词。
