本文主要介绍了2022年冬奥会中国最年轻的滑雪运动员——苏一鸣。
16．
句意：年轻的运动员们走出来，为自己赢得了名声。make a name for oneself“使自己成名”，固定短语，主语是Young athletes，表示复数，所以用they的反身代词themselves。故填themselves。
17．

20．
句意：从那以后，苏再也没有把滑雪板从脚上拿下来过，无论冬天还是夏天，白天还是晚上。根据“Su has not.... the snowboard off his feet”可知，此处考查动词短语take off“脱下；摘掉”。助动词has not后跟过去分词构成现在完成时结构。故填taken。
21．
句意：渐渐地，苏开始参加对抗成年人的比赛，并周游世界，在一个更好的环境中训练。take part in (doing) sth“参与做某事”，compete against“与……对抗”，固定短语；也可以填名词competition作宾语，应用名词复数表示泛指。故填competitions/competing。

24．
句意：我成功实现了我从小就有的梦想。根据“ I’ve always dreamed about winning this gold medal before 18 years old. I made it,”可知，此处指“成功”实现，空处缺少副词修饰动词realized，所以用succeed的副词successfully“成功地”。故填successfully。
25．
句意：我也想让每个人都知道，我不能只擅长一件事，但我可以在任何我喜欢的事情上做到最好。根据“but I can be the ... at anything I like”结合备选词可知，此处考查be good at“擅长”，结合语境可知，句中暗含比较，应用形容词good的最高级best。故填best。

34．句意：每天我做作业前都要复习一下。

35．句意：马克喜欢骑车。
考查特殊疑问句。根据划线部分cycling是具体的事情，所以用疑问词what进行提问；句中Mark是第三人称单数形式，enjoy是动词，意为“喜欢”，所以要用助动词dose；固定搭配enjoy doing sth.喜欢做某事，所以在变成疑问句时应在enjoy后面加doing。故填What；doing。

八、阅读回答问题(共10分)
Plastic straws (吸管) cause danger to the environment. They’re so small and they easily find their way into the ocean, where they can harm animals because they may eat them. Then, what can you use instead of plastic straws to protect the environment Here are some choices.
Bamboo straws
Fast-growing bamboo is ideal for making drinking straws. Many companies now produce bamboo straws, often without the use of chemicals (化学物质). Bamboo straws can be washed by hand and used again and again. When they do wear out, they break down easily.
Glass straws
Glass straws can also be reused, and if they’re clear, it’s easy to see whether they’re clean or not. Some companies make bent glass straws, which means you don’t have to tip (倾斜) your glass to drink with them. They are available in different colors and widths, so customers have many choices to choose from.
Bottles that come with straws
Many water bottles come with built-in straws. Although that straw may be made of plastic, you keep it and use it repeatedly. That means it probably won’t end up in the ocean any time soon. Water bottles can also replace (替代) paper cups, which cuts down on waste even more.
No straw
For many drinks, straws aren’t required; people can drink straight out of a cup. Businesses can cut down on the number of straws they use by just asking people if they want one. Many people hardly notice whether they have a straw or not.
Plastic straws are far from the only way to enjoy your favorite drink. Giving them up is an easy way to help take care of our planet.

八、阅读回答问题(共10分)
Plastic straws (吸管) cause danger to the environment. They’re so small and they easily find their way into the ocean, where they can harm animals because they may eat them. Then, what can you use instead of plastic straws to protect the environment Here are some choices.
Bamboo straws
Fast-growing bamboo is ideal for making drinking straws. Many companies now produce bamboo straws, often without the use of chemicals (化学物质). Bamboo straws can be washed by hand and used again and again. When they do wear out, they break down easily.
Glass straws
Glass straws can also be reused, and if they’re clear, it’s easy to see whether they’re clean or not. Some companies make bent glass straws, which means you don’t have to tip (倾斜) your glass to drink with them. They are available in different colors and widths, so customers have many choices to choose from.
Bottles that come with straws
Many water bottles come with built-in straws. Although that straw may be made of plastic, you keep it and use it repeatedly. That means it probably won’t end up in the ocean any time soon. Water bottles can also replace (替代) paper cups, which cuts down on waste even more.
No straw
For many drinks, straws aren’t required; people can drink straight out of a cup. Businesses can cut down on the number of straws they use by just asking people if they want one. Many people hardly notice whether they have a straw or not.
Plastic straws are far from the only way to enjoy your favorite drink. Giving them up is an easy way to help take care of our planet.
