3. enguins cannot fly but use their wings for swimming.

5. The changing (气候) is having an influence on the world's ecosystems.

1. support
2. hard
3. Penguins
4. rainfall
5. climate

1. “维持”对应的英文单词是“support”，且由于情态动词could后面接动词原形，所以此处填support。
2. 根据“We must try the best to solve it.”可知这个问题比较难，“hard”有“困难的”意思，且以h开头，符合题意。
3. 根据“cannot fly but use their wings for swimming”可知描述的是企鹅，“penguin”表示“企鹅”，且根据后面的“their”可知要用复数形式Penguins。
4. “降雨量”的英文表达是“rainfall”，是不可数名词，所以此处填rainfall。
5. “气候”的英文表达是“climate”，是不可数名词，所以此处填climate。

5. The programme was about customs in different (part) of the country.

1. differences
2. lying
3. anything
4. is
5. parts

1. “different”的名词形式是“difference”，且由于句中有“are”，所以“different”应转化为复数形式的名词“differences”。
2. “There was a child”表示“有一个孩子”，后面接现在分词“lying”表示孩子正躺在地上，构成过去进行时，同时“lying”也可以作为后置定语修饰“child”，表示“躺在地上的孩子”。
3. 在疑问句中，“something”通常变为“anything”，表示“任何事情”。
4. “half of the body's weight”指的是身体重量的一半，作为主语时，谓语动词用单数“is”。
5. “different”后接可数名词复数，“part”的复数形式是“parts”。

3. the temperature varies greatly from day to night

1. 第一句考查的是“栖息地”的英文表达以及主谓一致。根据中文提示“内蒙古的草原是马和牛的栖息地”，我们可以知道空格处应该填入“are home to horses and cows”。其中，“are”是系动词，因为主语“the grasslands”是复数形式；“home to...”表示“……的栖息地”；“horses and cows”表示“马和牛”。
2. 第二句考查的是原因状语从句。根据中文提示“沙漠非常干旱,因为降雨量极少”，我们可以知道空格处应该填入“because there is little rainfall”。其中，“because”引导原因状语从句；“there is”表示“有”；“little rainfall”表示“降雨量极少”。
3. 第三句考查的是主谓一致和固定短语。根据中文提示“并且在沙漠中昼夜温差极大”，我们可以知道空格处应该填入“the temperature varies greatly from day to night”。其中，“the temperature”作主语，表示“温度”；“varies”是谓语，表示“变化”；“greatly”是副词，修饰动词“varies”；“from day to night”是介词短语作时间状语，表示“从白天到晚上”。
4. 第四句考查的是定语从句。根据中文提示“他补充道,沙漠的气候十分恶劣,只有少数动植物能够在那里生存”，我们可以知道空格处应该填入“is so harsh that”。其中，“is”是系动词；“so...that...”引导结果状语从句，表示“如此……以至于……”；“harsh”是形容词，表示“恶劣的”。
5. 第五句考查的是主谓一致和固定短语。根据中文提示“他还提到,沙漠植物会在叶子中储存水分,许多动物可以从这些植物中获取水分”，我们可以知道空格处应该填入“store water in their leaves”。其中，“store”是谓语，表示“储存”；“water”是宾语；“in their leaves”是介词短语作地点状语，表示“在它们的叶子里”。

五、微写作 How much do you know about the polar ice? (At least 3-5 sentences)

The polar ice refers to the ice found in the Arctic and Antarctic regions. It plays a crucial role in regulating the Earth's climate by reflecting sunlight back into space. Due to global warming, the polar ice is melting at an alarming rate, causing sea levels to rise. This poses a serious threat to coastal communities and ecosystems around the world.
