Choose the best answer. —Look! The boys are playing basketball now. _______ boys are there on the playground? —There are thirteen boys. They often play basketball after school.
- A. How many
- B. How old
- C. Whose
- D. What colour
答案：A
解析：本题考查 How many 与 Whose 等疑问词的辨析，同时嵌入现在进行时语境。答句 There are thirteen boys. 回答的是「多少个」这一数量，问数量用 How many + 名词复数，故问句为 How many boys are there…，选 A。B. How old 问年龄，答句应是数字 + years old；C. Whose 问「谁的」，答句应含 my / his / 名词's 等所属关系词，注意 Whose 与 Who's（Who is）不同；D. What colour 问颜色。易错点：一是看到 boys 就误选 Whose，忽略了答句中的 thirteen 这一数量信息；二是把 How many 后的名词写成单数 boy，应为复数 boys；三是被 now 干扰，误以为本题考时态——now 只是情境背景，真正问的是数量。故选A。

The children are having a sports day. Read the sentences and answer the question. (1) Tom is running on the playground. (2) Lily is making a paper kite for the game. (3) Sam is swimming in the school pool. (4) Amy is sitting quietly and counting the balls. Question: Which word shows the -ing form that is made by dropping the silent letter e and then adding -ing?
- A. running
- B. making
- C. swimming
- D. sitting
答案：B
解析：本题考查动词 -ing 形式的三种构成规则，属于易混概念辨析。run 是“重读闭音节、末尾只有一个辅音字母”，要双写 n 再加 -ing，得 running；swim、sit 同理，双写 m 和 t 得 swimming、sitting；make 末尾的 e 不发音，构成 -ing 时要先去掉 e 再加 -ing，得 making。易错点：一是把 runing、swiming 当成正确形式，忘记双写规则；二是把 makeing 当成正确形式，忘记去 e；三是不看单词结构直接“加 -ing”。题干中的四个词分别对应三种规则，需要逐个判断后选出“去 e 加 -ing”的那一个。故选B。

The PE teacher is giving rules for the sports field. Read the four sentences and answer the question. (1) Run fast on the grass. (2) Don't talk loudly in the gym. (3) He is talking quietly in the library. (4) Please drink some milk after the game. Question: Which sentence is a negative imperative (否定祈使句) that tells people not to do something on the sports field?
- A. Run fast on the grass.
- B. Don't talk loudly in the gym.
- C. He is talking quietly in the library.
- D. Please drink some milk after the game.
答案：B
解析：本题考查祈使句的用法及其与现在进行时陈述句的区别。祈使句表示命令、请求或建议，句首用动词原形，通常省略主语 you；否定祈使句要在动词原形前加 Don't。A 项 Run fast… 是肯定祈使句，不是“否定”；B 项 Don't talk loudly… 以 Don't + 动词原形开头，是否定祈使句，符合题意；C 项 He is talking quietly… 是现在进行时的陈述句，有主语 he，不是祈使句；D 项 Please drink… 是肯定祈使句（表请求），也不是否定形式。易错点：一是误把有主语的陈述句当作祈使句；二是忘记否定祈使句必须用 Don't + 动词原形，写成 Don't talking 等错误形式；三是忽略题干中 negative（否定）这一关键限定。故选B。

根据句意和首字母提示，用合适的英语数字词或名词所有格完成句子，每空一词。
(1) —How many pencils do you have? —I have t________ (13).
(2) There are f________ (15) students in the sports team.
(3) —How many kites are there? —There are t________ (12).
(4) These are ________ (Amy and Sarah) new sports shoes. Amy's shoes are red and Sarah's shoes are blue.
(5) This is our classroom. That small gym is ________ (they). (用 they 的适当形式填空)
(6) —What's the date today? —It's May ________ (1). (用正确的英文序数词缩写填空)
答案：(1) thirteen
(2) fifteen
(3) twelve
(4) Amy's and Sarah's
(5) theirs
(6) 1st
解析：本题把 How many? 数量表达与名词所有格、物主代词、日期表达三个易混考点放在一起辨析。（1）thirteen 拼写是 thir + teen，不要写成 threeteen。（2）fifteen 是 fif + teen，不要受 five 影响写成 fiveteen。（3）twelve 是特殊变化词，不是 twoteen，注意 twelve 与 twenty 的区别。（4）是共有与各有的辨析：后半句明确说 Amy 的鞋是红色、Sarah 的鞋是蓝色，说明是各自拥有一双，因此用 Amy's and Sarah's（两人各自加 's）；若共有一件物品才用 Amy and Sarah's。（5）空格后没有名词，要用名词性物主代词 theirs，不能用 their（their 后必须接名词）。（6）May 1st 的 1st 不能写成 1th；同时注意 date（日期）与 day（星期）问句的区别，What's the date? 问几月几号。

体育课上，老师正在清点器材。请阅读下面的句子，完成任务。
Task 1: Look at the words below. Write the ordinal numbers for the cardinal numbers.（写出下列基数词对应的序数词。）
(1) five (2) twelve (3) twenty-one
Task 2: Read and answer.（根据提示完成句子。）
提示：They（他们），play basketball（打篮球）。用现在进行时写出完整句子。
Task 3: Translate into English.（把下面的标语翻译成英文。）
保持你的操场干净。
答案：(1) fifth, twelfth, twenty-first
(2) They are playing basketball.
(3) Keep your playground clean.
解析：本题把序数词、现在进行时（复数主语）和祈使句三个易混点放在一起对比考查。
Task 1：一般基数词加 -th，但 five→fifth（ve→fth）、twelve→twelfth（ve→fth）是特殊变化，twenty-one 属于复合数词，只变个位：twenty-first。易错：写成 fiveth、twelveth，或写成 twenty-oneth。
Task 2：主语 They 是复数，be 动词用 are（不能用 is）；play 直接加 -ing 变成 playing（不能写成 playyng）。句首字母要大写，句末加句号。
Task 3：祈使句以动词原形开头，"保持干净"用 Keep ... clean，clean 是形容词作宾语补足语，不能加 it 之类的多余成分；物主代词用 your 而不是 you。易错：Keep your playground clean it（逐字翻译多加成分）。
6解答题
学校运动会开始了！请阅读下面的情境，完成任务。
Task 1: Ask and answer about numbers.（根据情境补全对话，只填单词。）
情境：操场上有很多气球。Mike 想知道有多少个气球，他数了数，一共十五个。
Mike: ________ ________ balloons are there?
Amy: There are ________.
Task 2: Read and complete.（用括号内所给词的适当形式填空。）
情境：体育节上，同学们正在做运动。
(1) Look! The students ________ (run) on the playground.
(2) ________ (swim) is good exercise for our body.
Task 3: Make sentences.（连词成句，注意大小写和标点。）
(1) are, how, there, many, kites
(2) reading, is, fun, books
答案：Task 1: How many; fifteen
Task 2: (1) are running (2) Swimming
Task 3: (1) How many kites are there? (2) Reading books is fun.
解析：本题围绕 How many 问数量，并与动名词、现在进行时等易混概念对比。
Task 1：How many 后接可数名词复数，所以是 How many balloons，不能用 How much；数量 fifteen 拼写是 fif + teen，注意不是 fiveteen。易错：漏写复数 s，或把 fifteen 写成 fiveteen。
Task 2：(1) 主语 The students 是复数，be 动词用 are，run 双写 n 再加 -ing：are running；易错写成 is running 或 runing。(2) 动词 swim 的 -ing 形式作主语时要双写 m：Swimming，且位于句首要大写；动名词短语作主语看作一个整体，谓语用单数 is。易错：写成 Swim is ... 或 Swiming。
Task 3：(1) 特殊疑问句结构：疑问词 How many + 名词复数 + are there?，不能写成 How many kite are there（kite 要加 s）。(2) Reading books 是动名词短语作主语，谓语用单数 is，不能用 are；句首字母要大写，句末加句号。

Read the passage and answer the questions. Today is Sports Day at Sunny School. Look! The children are playing sports now. Amy is jumping rope. How many times can she jump? She can jump fifteen times. Tom is throwing a ball into a basket. He gets eighteen points. Lily is counting the ping-pong balls on the table. There are twelve ping-pong balls and eleven tennis balls on the table. The PE teacher, Mr. Green, is putting the balls into a big box now. How many balls are there on the table?
Questions:
1) How many times can Amy jump? (Write the number in English words.)
2) How many ping-pong balls are there on the table?
3) How many balls are there on the table in all? (Write the number in English words.)
4) What is Mr. Green doing now? (Answer in a full sentence.)
答案：1) She can jump fifteen times.
2) There are twelve ping-pong balls on the table.
3) There are twenty-three balls on the table in all. (十二加十一得二十三；若按本单元范围作答，答 twelve ping-pong balls and eleven tennis balls are on the table 也可酌情给分，但应写清两类球的数量。)
4) He is putting the balls into a big box now. / Mr. Green is putting the balls into a big box now.
解析：本题把数量问答（How many…?）与现在进行时放在体育节情境中综合考查。第1、3问答句要求把数字写成英文单词，十五是 fifteen（中间是 fif，不是 fiveteen），十三是 thirteen（thir + teen），这是本单元两大易错拼写。第2问必须看清限定词 ping-pong balls，只答 twelve，不要把网球数量混进来。第3问需要把十二和十一合起来数，超过本单元 eleven～twenty 范围时可写 two thirteen 之类不规范表达，正确应为 twenty-three。第4问由 now / Look! 判断动作正在进行，用现在进行时：主语 he（Mr. Green）是第三人称单数，be 动词用 is，put 要双写 t 再加 -ing 成 putting，写成 He puts… 或漏掉 is 都会失分。

Read the passage and answer the questions. Write your answers in English.
Today is Sports Day at Sunny School. The children are on the playground. There are many things to count. Look at the boxes. There are fifteen balls in the big box and eleven balls in the small box. The girls are skipping. There are eighteen skipping ropes on the ground. The boys are running. There are twelve water bottles beside the tree. Miss Green asks, "How many kites are there in the sky?" The children look up and count together: seventeen kites are flying in the blue sky. Miss Green says, "Sport is fun and good for our health. Let's play every day!"
(1) How many balls are there in the big box?
(2) How many skipping ropes are there on the ground?
(3) How many kites are there in the sky? Write the number word.
(4) Are there nineteen water bottles beside the tree? Answer with a full sentence.
(5) 数量词 thirteen 和 fifteen 的拼写容易出错。请把这两个数字写出来，并说出它们在拼写上的一个不同点（可用中文说明）。
答案：(1) There are fifteen balls in the big box. / Fifteen.
(2) There are eighteen skipping ropes on the ground. / Eighteen.
(3) Seventeen.
(4) No, there aren't. There are twelve water bottles beside the tree.
(5) thirteen; fifteen. 不同点：thirteen 是 thir + teen，fifteen 是 fif + teen（不是 five + teen；13 的开头是 thir，15 的开头是 fif）。
解析：本题考查 How many? 询问数量以及数字 eleven 到 twenty 的认读与拼写，同时结合体育运动情境。（1）（2）（3）只需回到短文对应句子抓数字，注意题干问的是 big box（十五个），不是 small box（十一个），也别把 ball 的总数（十五加十一＝二十六）误当答案。（4）是易错点：一般疑问句要用 No, there aren't. 回答，并最好补一句完整信息，不能只写 No。（5）是概念辨析：学生常把 thirteen 写成 threeteen（正确是 thir + teen），把 fifteen 写成 fiveteen（正确是 fif + teen）。另外提醒：teen 结尾的数字重音在后，twenty 是 twenty 不是 twoteen。数字词作答时首字母要大写（如 Seventeen）。
