阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Teenage life is full of challenges, and joining a club is a good way to face them. Our school running club has a rule: it is necessary ___ for ___ members to arrive at the playground before 6:30 a.m. Meanwhile, our coach often says, "It is thoughtful ___ of ___ you to bring water for your teammates after practice." To be honest, I am interested in taking part in the club, and I find that ___ running ___ every morning helps me relax.
According to the passage, which of the following sentences uses "of / for" and the non-finite form correctly?
- A. It is important for us to protect our personal information online, and it is kind of you to share the useful website with me.
- B. It is important of us to protect our personal information online, and it is kind for you to share the useful website with me.
- C. It is important for us protecting our personal information online, and it is kind of you to share the useful website with me.
- D. It is important for us to protect our personal information online, and it is kind of you sharing the useful website with me.
答案：A
解析：本题考查 It is + adj. + of/for sb. to do sth. 结构与非谓语作主语/宾语的辨析。
1）important 描述的是 to protect 这件事的重要性，而非 us 的品质，故用 for us to protect；kind 描述的是 you 的品格（善良），故用 of you。
2）非谓语形式：It is + adj. + for/of sb. 后必须接 to do（不定式），不能用 doing，因此 C 项 protecting 错；D 项 "it is kind of you sharing..." 也应改为 to share。
易错点：① 根据形容词与人的关系判断 of/for——描述人的品质（kind, nice, clever, careless, brave 等）用 of，描述事情的性质（important, difficult, easy, necessary 等）用 for；② 误把动名词当作不定式放在 sb. 之后；③ 忽视句子真正的逻辑主语。
综上，只有 A 项两处均正确。故选 A。
2选择题
阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Our school sports club offers teenagers both challenges and opportunities. Last term, Li Hua, who is interested in basketball, joined the club. However, he found that getting up early every morning was a real challenge. His coach advised him to keep a training diary. ___ (Write) down his progress every week made him more confident. Later, the coach suggested that he ___ (join) the school team. Now Li Hua says, "I never thought that being interested in a sport could change my teenage life so much."
Which of the following best completes the two blanks in the passage?
- A. Writing; (should) join
- B. To write; joining
- C. Writing; joined
- D. Write; (should) joining
答案：A
解析：本题考查动名词作主语与 suggest 后接宾语从句（省略 should 的虚拟语气）的辨析。
1）第一空在句中作主语，表示一般性、习惯性的活动，动词原形不能作主语，应用动名词 Writing（首字母大写因位于句首）。B 项 To write 虽也可作主语，但常表示具体的、一次性的或将来的动作，且第二空错；D 项 Write 为原形，不能作主语。
2）第二空考查 suggest + that 从句，从句谓语用 (should) + 动词原形，should 可省略，故填 (should) join。B 项 joining、D 项 joining 均非谓语形式，不能作从句谓语；C 项 joined 时态与语态均不符合 suggest 的虚拟语气要求。
易错点：① 混淆动名词与不定式作主语；② 误认为 suggest 后接 to do 作宾补；③ 忘记 should 可省略，误填 joining 或 joined。
综上，两空应为 Writing; (should) join。故选 A。
3选择题
阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Teenage life is full of challenges and opportunities. Last month, our school set up a new basketball club, which attracted more than sixty students. Li Ming, who is my deskmate, joined the club at once because he is interested in playing basketball. As we all know, doing sports regularly helps teenagers keep healthy and stay energetic. However, some students think that joining a club takes up too much study time, which is a fact we cannot ignore. In fact, the club members are required to finish their homework before training, and their grades have improved since then.
Which of the following sentences uses "as" correctly to introduce a non-restrictive attributive clause?
- A. As we all know, doing sports regularly helps teenagers keep healthy.
- B. We all know as doing sports regularly helps teenagers keep healthy.
- C. Doing sports regularly as helps teenagers keep healthy, we all know.
- D. Doing sports regularly helps teenagers keep healthy, that we all know.
答案：A
解析：as 引导非限制性定语从句时意为“正如”，常与 know, see, expect 等动词连用，位置灵活，可放句首、句中或句末，常用结构为 as we all know / as is known to all。A 项将 as we all know 放在句首，指代后面整个主句，结构与语义均正确。B 项语序混乱，as 后不能直接接 doing 引导的成分作宾语；C 项把 as 从句硬插在主句中间，破坏了主句结构；D 项非限制性定语从句不能用 that 引导，属于典型易错点。故选A。
4选择题
Read the following passage and choose the best answer.
Teenage life is full of challenges, but it is also full of opportunities. This term, our school sports club is trying something new. According to the club schedule, the basketball team ______ to a neighboring school for a friendly match next Friday afternoon.
Which of the following best completes the blank?
- A. will travel
- B. is traveling
- C. travels
- D. has traveled
答案：B
解析：本题考查现在进行时表示将来计划。句中 According to the club schedule（根据社团日程安排）明确提示这是一个已安排好、确定的计划，且 travel 属于位置移动类动词，常用于现在进行时表将来，故用 is traveling。易错点：①看到 next Friday 就机械地选 will travel（A），will 常表示临时决定或主观预测，不体现「已安排」；②travels（C）是一般现在时，表示习惯或客观事实，不能表示将来的计划；③has traveled（D）是现在完成时，与将来时间 next Friday 矛盾。故选B。
5填空题
阅读下面短文，在空白处填入 1 个适当的单词或括号内所给词的正确形式。
Teenage life is full of (1) ________ (challenge), and joining a club is a good way to face them. I am interested in (2) ________ (play) basketball, so I joined the school basketball club last month. Since then, I (3) ________ (make) quite a few new friends. Our coach often tells us that we (4) ________ (should) warm up before every game. He also says what (5) ________ matters most is teamwork, not just winning. The training is tiring, but it has taught me (6) ________ patience and confidence. Every time I step onto the court, I feel that this club is (7) ________ wonderful opportunity for me to grow. Now I truly understand (8) ________ teenagers need both sports and study to keep a healthy life.
答案：(1) challenges (2) playing (3) have made (4) should (5) that (6) the (7) a (8) why
解析：本题综合考查本册多个核心考点，需逐空分析。(1) challenge 为可数名词，前面无冠词且谓语 are 提示主语为复数，故用 challenges；易错点是拼写错 challenge（误写成 challange）。(2) be interested in 后接名词或动词 -ing 形式，in 是介词，不能接动词原形，故填 playing；这正是本课重点易错点「interested 后误加原形」。(3) since then 是现在完成时的典型标志词，故用 have made；若误用 made 则忽略了与现在的联系。(4) 情态动词 should 后必须接动词原形，直接填 should，不能写 shoulds。(5) 空格后 "...matters most is teamwork" 中主语从句结构完整（that 不作成分，仅起连接作用），故用 that；若误填 what，会导致 matters 前多出一个成分，句意重复。(6) patience and confidence 在此为特指的抽象品质，且 taught me 后表示「教会我耐心与自信」，此处用 the 更符合语境；也可填出具体语境下的特指。(7) opportunity 为可数名词单数，wonderful 以辅音音素开头，故用不定冠词 a。(8) understand 后为宾语从句，从句结构完整但缺少原因状语，且句意为「明白为什么青少年需要……」，故用 why。综上，重点在于：be interested in + doing、现在完成时标志词 since then、that 与 what 在名词性从句中的区分、should 后接原形。
6填空题
阅读下面短文，根据括号内所给词的适当形式填空，使短文内容完整、正确。
Many teenagers are interested in ______1______ (join) a school club, but they often find that choosing the right one is a real ______2______ (challenge). If I ______3______ (be) you, I would talk to the club leaders first. In fact, it ______4______ (be) the school sports club that offers teenagers the most chances to exercise and make friends. Look! The notice on the wall says the new members ______5______ (meet) at the gym at 4 p.m. tomorrow.
答案：1. joining。be interested in 后接名词或动词 -ing 形式，故填 joining。
2. challenge。此处需要名词作表语，a real challenge 表示「一个真正的挑战」，注意拼写 challenge（易错拼成 challange）。
3. were。与现在事实相反的虚拟条件句，if 从句用一般过去时，be 动词一律用 were（易错用 was）。
4. is。强调句型 It is + 被强调部分 + that...，强调主语 the school sports club（单数），故用 is；去掉 It is 和 that 后句子成分完整，可判断为强调句。
5. are meeting。由 Look! 和 tomorrow 以及日程安排（The notice says...）可知，此处表示已安排好的计划，用现在进行时表将来，主语 the new members 为复数，故填 are meeting。
解析：本题集中辨析四组易混概念：①interested in 后只能接名词或动词 -ing，学生常误加动词原形（join），正确为 joining；②challenge 为可数名词，注意拼写（双 l 不成立，正确为 challenge）；③虚拟条件句中 be 一律用 were，不能用 was，主句才用 would + 动词原形；④强调句 It is... that... 与主语从句的辨析：去掉 It is 和 that 后句子成分仍完整即为强调句，此处强调主语，谓语动词随被强调的单数名词用 is；⑤现在进行时表将来要有「安排、计划」的语境线索（The notice says...），不要一见 tomorrow 就用 will。
7解答题
根据括号内的提示完成句子，并按要求改写或说明理由（要求用英语作答）。
1. 我对加入学校跑步俱乐部很感兴趣。（be interested in）
2. 老师建议我们每天锻炼半小时以保持健康。（should）
3. The coach said something at the meeting. It encouraged the whole team.（用 that 或 what 合并为一个含主语从句的句子）
4. The student who was chosen by the coach is my deskmate.（用非谓语动词改写，去掉定语从句）
5. We plan to travel ________ bus to the stadium, and our city is famous ________ its basketball team.（用恰当的介词填空）
答案：1. I am interested in joining the school running club.
2. The teacher suggests that we (should) exercise for half an hour every day to keep fit. / We should exercise for half an hour every day to keep fit.
3. What the coach said at the meeting encouraged the whole team.
4. The student chosen by the coach is my deskmate.
5. by; for
解析：本题为综合解答题，聚焦「概念辨析」，覆盖本册多个易混考点。
第 1 句：be interested in 后接名词或动词 -ing，故 join 必须写成 joining；易错点是误写成 interested in join。同时 challenge 等词拼写要注意。
第 2 句：should 表建议，后接动词原形 exercise，不能加 -s；suggest 后宾语从句可用 (should) + 动词原形的虚拟语气结构。易错点是把 should 后写成 exercises 或 to exercise。
第 3 句：主语从句 "...said at the meeting" 中 said 缺宾语，需用 what 充当 said 的宾语，故填 What；若用 that 则从句成分残缺。注意 What 首字母大写，且 what 在从句中作成分，这是与 that 的核心区别。
第 4 句：定语从句 "who was chosen by the coach" 为被动且含 be 动词，可简化为过去分词短语 chosen by the coach 作后置定语；易错点是误用 choosing（主动）或保留 who was。
第 5 句：by + 交通工具单数名词（不加冠词）表示方式，故 by bus；be famous for 表示「因……而著名」，be famous as 表示「作为……而著名」，此处指因篮球队而出名，故用 for。
综合来看，本题辨析四组易混概念：be interested in + doing 与动词原形、should + 原形与其他形式、that 与 what 在名词性从句中的分工、by 交通工具与 in + 限定词 + 名词、famous for 与 famous as。
8解答题
根据中文提示和括号内所给词的适当形式完成句子，注意非限制性定语从句与被动语态的正确使用。
1. 校园体育社团的成员们每天训练两小时，这件事全校都知道。（as）
The members of the school sports club train for two hours every day, ________ ________ everyone in the school knows.
2. 互联网已经改变了我们锻炼身体的方式，这是一个事实。（which）
The internet has changed the way we take exercise, ________ is a fact.
3. 每年都有许多新运动社团在我们学校成立。（被动语态，一般现在时）
Many new sports clubs ________ ________ (set up) in our school every year.
4. 上学期，我们学校举办了一场健康生活讲座。（被动语态，一般过去时）
Last term, a lecture on healthy living ________ ________ (hold) in our school.
5. 我对加入跑步社团感兴趣，因为跑步有助于保持健康。（interested）
I am interested in ________ (join) the running club, because running helps us keep fit.
6. 用 interested in 写一个英文句子，谈谈你自己的兴趣爱好。（不超过 15 个单词）
答案：1. as is
2. which
3. are set up
4. was held
5. joining
6. 参考答案（合理即可）：I am interested in playing badminton with my classmates after school.
解析：1. as 引导非限制性定语从句，意为“正如”，可放句末，固定搭配 as everyone knows；易错：误用 that（非限制性定语从句不能用 that），或误写成 because（那是原因状语从句）。
2. which 引导非限制性定语从句，指代前面整个主句内容，仅表示“这件事”，放在主句之后；易错：误填 as（此处无“正如”含义）。
3. 主语 clubs 是动作承受者，一般现在时被动结构为 am/is/are + 过去分词，主语复数用 are，set 的过去分词仍是 set：are set up；易错：写成 are setting up（用了现在分词）或时态误用 was set up。
4. last month/last term 明确是过去时间，被动结构为 was/were + 过去分词，主语 a lecture 为单数：was held；易错：时态与原句不一致，写成 is held。
5. be interested in 后接名词或动词 -ing 形式，故填 joining；易错：interested 后误加动词原形 join。
6. 本小题为开放题，句式正确、语意合理即可，注意 interested in 后接 -ing 形式；易错：拼写错误（如写成 intrested）或漏写 in。
