Scientists believe the earth is 4.6 billion years old. But the mountains, valleys, hills, rivers, ¹
deserts

youngest
(young) sea in the world is the Baltic Sea, about 12,000 years old.
The earth ³
changes
(change) all the time because of volcanoes, earthquakes and of course, wind and rain. Some of these changes are very slow and others are quick. Water and ice can make very great changes to the planet. For example, rivers of ice can cut through mountains and make lakes and deep valleys. Many volcanoes are under the oceans and sometimes they form new islands. This is ⁴
happening
(happen) in the South Pacific, near Tonga.
It's normal for our planet to change, but at the moment, scientists think it's changing faster than usual. Some deserts ⁵
are growing
(grow) and many forests are getting smaller. The weather is getting wetter in some places and drier in others, and there are more big storms. According to the research, the sea level ⁶
will keep
(keep) rising in the next hundred years. So many cities will possibly be covered by water and many of the most productive ⁷
farming
(farm) areas will be lost. Some island countries may disappear on the map of the world.
These changes will bring great harm to the planet. However, they can be ⁸
useful
(use) to some people. For example, as the Arctic is getting warmer, some people in Greenland now own businesses and sell vegetables that they grow on ⁹
their
(they) land. That ¹⁰
wasn't

【分析】
做这类提示词型短文词汇运用题,首先第一步要通读全文,明确文章主题是介绍地球的演变和当下的气候变化趋势,把握整体的时态逻辑。接下来逐个分析空格:首先观察空格前后的成分,判断空格所需的词性,再结合并列结构、时间标志词、固定搭配、形容词最高级的使用规则等确定变形方向,最后把所有答案代入全文通读,验证语义和语法是否通顺,避免出现不符合语境的错误。
【解析】
1. 空格前and连接并列的名词成分,前面的mountains、valleys、hills、rivers均为可数名词复数,desert是可数名词,要和并列成分形式保持一致,因此变为复数deserts。
2. 空格后有范围限定"in the world",且空格前有定冠词the,提示此处要用形容词最高级,young的最高级形式为youngest,表示世界上最年轻的海。
3. 本句描述客观事实:地球一直处于变化中,主语the earth是第三人称单数,一般现在时的谓语动词要变为三单形式changes。
4. 空格前有be动词is,语境表示前文提到的火山形成新岛屿这件事当下正在汤加附近的南太平洋发生,用现在进行时,happen的现在分词形式为happening。
5. 后文并列结构"many forests are getting smaller"是现在进行时,前后语境保持一致,主语some deserts是复数,因此现在进行时结构为are growing,表示部分沙漠正在扩张。
6. 空格后有时间标志"in the next hundred years"(未来一百年),是一般将来时的提示,因此填will keep。
7. 空格修饰名词areas,构成固定搭配farming areas,意为农耕区/农业产区,因此将farm变为动名词形式farming作定语。
8. 空格前是be动词are,此处需要形容词作表语,use对应的形容词形式是useful,意为有用的。
9. 空格后是名词land,需要形容词性物主代词修饰名词,人称代词they对应的形容词性物主代词是their,意为他们的。
10. 空格后有过去时间标志"50 years ago",描述过去的状态,用一般过去时,主语that是单数,be动词的否定形式为wasn't。
【答案】
1. deserts 2. youngest 3. changes 4. happening 5. are growing 6. will keep 7. farming 8. useful 9. their 10. wasn't
【知识点】
词形转换,动词时态,形容词最高级
【点评】
本题是初中阶段典型的语篇型词汇变形考题,考点覆盖了名词复数、物主代词、词性转换、多种时态辨析等核心基础知识点,既考察基础语法规则的掌握,也要求学生结合上下文的并列逻辑、语境提示判断正确形式,避免孤立记忆语法点的误区,整体考点设置梯度合理。

【分析】
这是一道情景类动词词义辨析题,解题时首先通读完整对话,明确对话核心是讨论“双减”政策的适用人群范围,确定空缺处需要填入能表达“覆盖、涉及对应人群”含义的动词,之后逐一比对四个选项的词义,把不符合对话逻辑的选项逐一排除,最终匹配出最贴合语境的答案。
【解析】
先翻译对话大意:——“双减”政策覆盖我国所有民众吗?——当然不是,它只针对学生。
逐个辨析选项:
1. 选项A:catch意为“抓住、赶上”,代入句意完全不符合讨论政策适用范围的语境,排除;
2. 选项B:cover有“覆盖、涉及、适用于”的含义,可用来表示政策类规则的覆盖人群范围,完全契合对话逻辑;
3. 选项C:cost意为“花费(金钱/时间)、付出代价”,和题干讨论的人群范围话题无关,排除;
4. 选项D:close作动词时意为“关闭”,语义完全不通顺,排除。
综上正确选项为B。
【答案】
B
【知识点】
动词词义辨析,语境选词
【点评】
本题结合热点“双减”政策设置真实情景,考察常见动词的延伸用法,不少学生仅了解cover表示物理层面“覆盖”的基础含义,对其描述政策覆盖人群的用法不熟悉,容易出现错选,日常学习要注意积累核心词汇的多层表意。
