根据语境，选择最佳选项填空。
My deskmate Li Ming is a true friend. Whenever I have difficulty in my studies, he is always ready to help me. It is generous ______ him to share his notes with me, and it is necessary ______ us to trust each other in our daily life.
- A. of; of
- B. of; for
- C. for; of
- D. for; for
答案：B
解析：本题考查 It is + adj. + of/for sb. to do sth. 结构。第一空，generous（慷慨的）描述的是 Li Ming 这个人的品质特征，属于描述人的性格、品质的形容词，故用 of，即 It is generous of him to share...。第二空，necessary（必要的）描述的是 to trust each other 这件事的性质，说明"我们互相信任"这件事是必要的，而非评价"我们"的品质，故用 for。易错点：一是误认为 generous 修饰的是"分享笔记"这件事而用 for；二是忽略形容词的逻辑指向，机械地两个空都选同一介词。判断口诀：形容词评价人品用 of，形容词评价事情用 for。故选B。
2选择题
根据语境，选择最佳选项填空。
Some students think that friends should share everything with each other. ______ is often pointed out, however, true friendship is built on trust and honesty rather than on secrets or lies.
- A. Which
- B. As
- C. That
- D. It
答案：B
解析：本题考查非限制性定语从句中 as 与 which 的区别。从句位于句首，且意为"正如……所指出的"，表示"正如"的含义，与 point out, know, see, expect 等动词连用，此时只能用 as 引导非限制性定语从句，即 As is often pointed out, ...。which 引导的非限制性定语从句不能置于句首，且只指代前面的事实，不含"正如"之意；that 不能引导非限制性定语从句；it 若填入则句子缺少谓语动词的从属连接，结构不成立。易错点：一是看到逗号就机械选 which，忽略从句在句首这一位置限制；二是把 as 从句误认为原因状语从句（"因为"），此处应理解为"正如"；三是误用 that 引导非限制性定语从句。故选B。

Choose the best answer to complete each sentence.
1. ________ time went by, the volunteers of the wildlife club realized that protecting rare animals required more than good intentions.
A. While
B. As
C. When
D. Until
2. If I ________ you, I would tell the truth to my friend immediately, because honesty is the base of friendship.
A. am
B. was
C. were
D. will be
- A. While; am
- B. As; were
- C. When; was
- D. Until; will be
答案：B
解析：本题把两个小题合并为一道选择题，需同时满足两空。
第一空：主句 "the volunteers... realized" 表示一个渐进的过程，从句 "time went by" 表示"随着时间推移"，属于"随着……"的伴随变化，应用 as。while 强调"在……期间"，后接延续性动词，常与进行时连用，不能表示"随着"；when 侧重"当……时"，指某一时刻；until 表示"直到……"，与句意不符。故第一空应为 As。
第二空："If I were you" 表示与现在事实相反的虚拟条件句，if 从句用一般过去时，且 be 动词一律用 were（即使主语是 I）；主句用 would + 动词原形（would tell）。真实条件句的 am/was 均不成立，will be 时态错误。故第二空应为 were。
综合两空：As; were，对应选项 B。易错点：①第一空误选 when，未识别"随着"的含义；②第二空受口语影响误选 was，虚拟语气中 I 后必须用 were；③只看第一空或只看第二空就下结论，导致搭配错位。
故选B。
4填空题
阅读下面短文，在空白处填入括号内所给词的适当形式，或在空白处填入一个适当的词，使短文内容完整、连贯。
A true friend is someone who trusts you and shares with you both happiness and trouble. As the old saying goes, "A friend in need is a friend indeed." Last month, our class visited a forest park to learn about environmental protection. Li Ming, ___1___ has been my best friend since childhood, went with me. On the way, he said to me, "I ___2___ (pick) up plastic bottles along the river tomorrow." The next day, he told me that he ___3___ (pick) up plastic bottles along the river that day. We worked together in a small valley ___4___ many birds live. The trees ___5___ (plant) by volunteers last year are growing well now. Though we were tired, we felt happy, ___6___ we knew we had done something useful for nature. I believe friendship ___7___ (build) on trust and honesty will last forever.
1. ________
2. ________
3. ________
4. ________
5. ________
6. ________
7. ________
答案：1. who
2. will pick / am going to pick
3. would pick
4. where
5. planted / that were planted / which were planted
6. because
7. built / that is built / which is built
解析：本题综合考查定语从句、间接引语、非谓语动词与基础连词，均落在本单元核心考点上。
1. 先行词 Li Ming 指人，关系词在从句中作主语，用 who（也可用 that），不能用 where/when。
2. 直接引语中时间状语是 tomorrow，主句为一般过去时（said），转述时要用过去将来时 would pick；填 will pick 视为保留原意的可接受答案。易错：不作时态推移，仍写 will pick 且不理解考查意图。
3. 间接引语中 said 变为 told，tomorrow 相应变为 that day，时态须后移一档：一般将来时 → 过去将来时 would pick。这是本单元两大易错点之一（时态没有相应变化）。
4. 先行词 a small valley 是地点，且从句 many birds live 主谓结构完整、缺少地点状语，故用关系副词 where（＝in which）。易错：看到地点就写 which，或从句缺成分时误用 where。
5. trees 与 plant 是被动关系，作后置定语用过去分词 planted（＝which/that were planted）。易错：用现在分词 planting 表被动，或忘记与主句谓语 are growing 区分。
6. 前后为因果关系，用 because。易错：用 although 造成逻辑矛盾。
7. friendship 与 build 为被动关系，用过去分词 built 作后置定语；若填定语从句 that/which is built 亦正确。易错：逻辑主语判断错误，误填 building。
5解答题
根据题目要求完成下列各小题。
1. 将下列每对句子合并为一个含定语从句的复合句。
(1) I will never forget the day. I joined the environmental club on that day.
(2) The girl is my deskmate. The girl is talking with our teacher over there.
(3) This is the reason. He was late for the tree-planting activity for this reason.
2. 将下列直接引语改为间接引语。
(4) Tom said, "I am glad to share these books with you."
(5) Mary said to me, "I will help you clean up the park tomorrow."
3. 按要求改写句子。
(6) They visited the nature reserve last weekend.（改为一般疑问句）
(7) She planted a young tree in the garden yesterday.（改为否定句）
4. 用所给动词的适当形式填空。
(8) ________ (protect) the environment, we should reduce the use of plastic bags.
(9) ________ (see) from the top of the hill, the forest looks very beautiful.
(10) ________ (encourage) by the teacher, the students took an active part in the clean-up activity.
答案：1. (1) I will never forget the day when/on which I joined the environmental club.
(2) The girl who/that is talking with our teacher over there is my deskmate.
(3) This is the reason why/for which he was late for the tree-planting activity.
2. (4) Tom said that he was glad to share those books with me.
(5) Mary told me that she would help me clean up the park the next day.
3. (6) Did they visit the nature reserve last weekend?
(7) She didn't plant a young tree in the garden yesterday.
4. (8) To protect
(9) Seen
(10) Encouraged
解析：1. 关系词选用三步：①找先行词；②判断人/物/时间/地点/原因；③判断关系词在从句中充当主语、宾语还是状语。
(1) 先行词 the day 表时间，从句 I joined the environmental club 结构完整、缺时间状语，用 when 或 on which。易错：写成 which（缺介词）。
(2) 先行词 the girl 指人，关系词在从句中作主语，用 who/that。易错：用 which；作宾语时才可省略，此处作主语不可省。
(3) 先行词 the reason，固定用 why（＝for which）。易错：误用 because/that。
2. 间接引语转换两大人称、时态要点：
(4) I → he；am → was；these → those；you → me。易错：人称不变，仍写 I am。
(5) said to me → told me；I → she；will → would；you → me；tomorrow → the next day。易错：只换人称不换时态。
3. 一般过去时句型转换：借助助动词 did，同时把谓语动词过去式还原为原形。
(6) visited → Did … visit。易错：Did 后仍写 visited。
(7) didn't + plant。易错：didn't planted。
4. 非谓语作状语：
(8) 表目的，用不定式 To protect。
(9) 逻辑主语 the forest 与 see 是被动关系，用过去分词 Seen。易错：Seeing（主动误用）。
(10) 逻辑主语 the students 与 encourage 是被动关系（受到鼓励），用过去分词 Encouraged。易错：Encouraging。
6解答题
Read the following short passage and complete the tasks below.
Last term our class started a "Green Campus" project. Li Hua and I planted trees together every weekend. One Saturday, heavy rain flooded the small path near our garden. I slipped and hurt my ankle, but Li Hua did not leave me alone. He trusted me to stay calm and helped me back to the classroom. Later he said, "I will share my notes with you so that you won't miss any lessons." Now I understand that a friend in need is a friend indeed, and that friendship is built on trust and honesty.
Task 1: Rewrite the underlined sentence "He trusted me to stay calm and helped me back to the classroom." in the emphatic pattern to emphasize the subject "Li Hua".
Task 2: Change the direct speech "Later he said, "I will share my notes with you so that you won't miss any lessons."" into indirect speech.
Task 3: Fill in each blank with the correct form of the word given in brackets.
(1) ________ (protect) the environment is everyone's duty.
(2) The teacher suggested we ________ (join) the tree-planting club next term.
答案：Task 1: It was Li Hua who/that trusted me to stay calm and helped me back to the classroom.
Task 2: Later he said that he would share his notes with me so that I wouldn't miss any lessons.
Task 3: (1) Protecting; (2) (should) join.
解析：Task 1 考查强调句型 It is/was + 被强调部分 + that/who + 其余部分。强调主语 Li Hua 是人，用 who 或 that 均可；因事情发生在过去，用 It was；去掉 It was 与 who/that 后，"Li Hua trusted me..." 句子成分依然完整，说明是强调句而非主语从句。易错点：①误用 which；②忘记把剩余部分动词保持原时态，误写成 has trusted；③写成 It was Li Hua who trusted me to stay calm and helps me back，前后时态不一致。
Task 2 考查直接引语变间接引语。人称要变：I → he，you → me；时态要退一步：will → would，won't → wouldn't；so that 引导的目的状语从句一并转述。易错点：①人称不变，写成 he would share his notes with you；②时态不变，写成 will share；③漏掉 so that 从句中 won't → wouldn't 的变化。
Task 3 (1) 动名词作主语，动词原形不能作主语，故填 Protecting。(2) suggest 后接宾语从句用 (should) + 动词原形，should 可省略，故填 (should) join。易错点：①写成 To protect 作主语表具体一次动作，此处表示一般性活动应用动名词；②suggest 后误接 to join。
7解答题
阅读下面短文，在空白处填入一个适当的词或用括号内所给词的适当形式填空。
Last Friday, our class held a discussion about what makes a good friend. Wang Lei said, "A true friend 1. ________ (trust) you and never tells your secrets to others." Then he added, "My deskmate always 2. ________ (share) his notes with me when I am ill." Our teacher smiled and told us 3. ________ friendship is built on trust and honesty.
After the discussion, Wang Lei told me he 4. ________ (be) very happy because his old friend had written to him. In the letter, his friend said, "I 5. ________ (visit) your city next month." So Wang Lei said his friend 6. ________ (visit) his city the next month. We all agreed that a friend in need is a friend indeed.
答案：1. trusts 2. shares 3. that 4. was 5. will visit / am visiting 6. would visit
解析：本题综合考查主谓一致、名词性从句连接词与间接引语的时态变化。1. 主语 A true friend 是第三人称单数，且陈述一般事实，用一般现在时 trusts。2. 主语 My deskmate 为第三人称单数，always 表示习惯性动作，用 shares。3. told us 后接宾语从句，从句 friendship is built on trust and honesty 结构完整、不缺成分，只用 that 起连接作用；此处若填 what 就错了，因为 what 必须在从句中充当主语、宾语或表语。4. told 后的宾语从句转述过去发生的情况，时态相应后退：is → was。5. 直接引语中 "next month" 表示将来计划，可用 will visit，也可用现在进行时 am visiting 表示已安排好的计划。6. 转述时人称、时态都要相应变化：will → would，next month → the next month。易错点：一是转述时人称没有相应变化；二是时态不后退（写成 is / will）；三是 that 与 what 混淆。
8解答题
根据括号内的提示完成下列句子，每空一词。
1. The plan ________ (discuss) at yesterday's class meeting is about protecting rivers near our school.（用所给动词的适当形式填空）
2. Li Ming said, "I am proud of my honest friend."（改为间接引语）
Li Ming said ________ ________ ________ proud of ________ honest friend.
3. 请把这张志愿者活动的照片发给我。（用 send 的短语动词翻译，注意代词宾语的位置）
Please ________ this photo ________ ________. / Please ________ ________ this photo.
4. Look! The schedule says the tree-planting activity ________ (start) at 8 a.m. tomorrow.（用所给动词的适当形式填空）
答案：1. discussed
2. that he was; his
3. send; to me; send me
4. is starting
解析：1. 考查非谓语作定语：plan 与 discuss 是被动关系，且该动作已完成，用过去分词 discussed 作后置定语，相当于 which was discussed。易错点：误用 discussing（逻辑关系错，plan 不会主动讨论别人）。2. 考查直接引语变间接引语：said 后用 that 引导宾语从句；人称 I → he，时态 am → was，物主代词 my → his。易错点：漏掉 that 或人称、时态不变化。3. 考查动词+副词短语动词与宾语位置：send sth. to sb. 或 send sb. sth.；本句宾语为名词 this photo 时可后置，但代词 me 只能作间接宾语放在动词后，不能写成 send this photo to me it 或 send to me it。答案也可写作 send me this photo。4. 考查现在进行时表将来：时间表、日程表上已安排好的计划（the schedule says）常用现在进行时 is starting，而不用 will start。易错点：一见 tomorrow 就用一般将来时。
