Read the passage and choose the best answer.
Uncle Bill has a big farm. There are many animals and vegetables on it. Look at these. They are red and round. They are tomatoes. Are those potatoes? No, they aren't. They are carrots. The carrots are orange. Over there, there are five sheep. Sheep eat grass. Are these cows? Yes, they are. The cows give us milk every day. My favourite animal on the farm is the horse. It can run very fast.
Which of the following is TRUE about Uncle Bill's farm?
- A. The carrots on the farm are red and round.
- B. There are five sheep on the farm.
- C. The potatoes are orange.
- D. The cows can run very fast.
答案：B
解析：本题考查短文细节理解。根据短文“Over there, there are five sheep.”可知农场里有五只绵羊，B项正确。A项错误：red and round（又红又圆）描述的是tomatoes，不是carrots，胡萝卜是orange（橙色的）。C项错误：orange的是carrots，短文并未说土豆是橙色的。D项错误：能跑得很快的是the horse（马），不是the cows。易错点是被文中反复出现的蔬菜名称干扰，张冠李戴，需把每个颜色/特征与对应动物、蔬菜仔细匹配。故选B。

Look at the farm. There are many animals near the river. You want to know if those animals are horses. How should you ask? Choose the best question.
- A. Are those horses?
- B. Is those horses?
- C. Are these sheeps?
- D. Are that horses?
答案：A
解析：本题考查一般疑问句 Are these / Are those 的用法及名词复数。问“那些是马吗”用 Are those + 名词复数，故 Are those horses? 正确。B项错误：those 是复数，be 动词应用 are，不能用 is。C项错误：一是 those animals 指“那些”，应用 those 而非 these；二是 sheep 单复数同形，没有 sheeps 这种写法。D项错误：that 是单数，与 are 不搭配，且 horses 是复数，前后不一致。易错点有两个：一是问复数时名词忘记加 s（如写成 horse）；二是误以为 sheep 的复数是 sheeps。故选A。

阅读下面的对话，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Amy and her little brother Sam are visiting Uncle Li's farm on Sunday morning.
"Look at those little trees over there!" says Sam. "What are they?"
"They are tomato plants, and those round red things on them are tomatoes," says Amy. "Are these carrots under the ground?"
"Yes, they are. We pull them out of the ground," says Uncle Li.
"How about those animals near the river?" asks Sam.
"They are sheep. Look, one sheep is eating grass and the other three are sleeping," says Uncle Li.
"Wow, the baby sheep are so cute! They like to run on the grass," says Amy.
Which of the following sentences is TRUE according to the passage?
- A. The tomatoes are growing under the ground.
- B. There are four sheep near the river.
- C. The carrots are round and red.
- D. The baby sheep like to swim in the water.
答案：B
解析：这是一道细节判断题。A 项错误：文中说 carrots 在地下（"carrots under the ground"），tomatoes 长在 tomato plants 上，不是在地下。B 项正确：文中说 one sheep is eating grass and the other three are sleeping，即 1 + 3 = 4 只羊。C 项错误：round and red 描述的是 tomatoes，不是 carrots。D 项错误：文中说小羊喜欢在草地上跑（run on the grass），不是在水里游泳。易错点：一是看到 cute 就联想到 Story time 里小鸭子喜欢 swim in the water，凭印象作答而未回文核对；二是数羊时容易漏掉 one 与 the other three，只数出 3 只；三是混淆 tomato 和 carrot 的生长位置。故选B。

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。
Hello! I'm Amy. Today I visit a big farm with my family. There are many vegetables and animals on the farm. Look at these. Are these tomatoes? Yes, they are. They are red and round. Look at those. Are those potatoes? No, they aren't. They are carrots. They are long and orange. Near the river, there are some sheep and cows. Do you know? Sheep is a special word. One sheep, two sheep, three sheep. They all look the same!
What are the long and orange vegetables on the farm?
- A. Tomatoes.
- B. Potatoes.
- C. Carrots.
- D. Sheep.
答案：C
解析：本题考查短文细节信息的定位与辨认。定位到原文 "Look at those. Are those potatoes? No, they aren't. They are carrots. They are long and orange."，说明那些又长又橙色的蔬菜是 carrots。易错点：一是受上一句 "Are those potatoes?" 的干扰误选 B，但原文明确回答了 "No, they aren't"；二是没读懂 long and orange 这一描述，凭感觉选了第一种提到的 tomatoes。蔬菜是农场种的，sheep 是动物，D 明显不合题意。故选C。
5填空题
根据短文内容，用括号内所给词的适当形式填空。
This is our school farm. We have many nice things here. There ______ a big potato and five red tomatoes in the basket. (be) Are ______ (this) carrots yours? Yes, they are. I can see three ______ (sheep) and two ______ (hen) on the grass. ______ those horses over there? No, they ______. They are cows. (be)
答案：is; these; sheep; hens; Are; aren't
解析：本题考查 There be 句型的就近原则、指示代词的单复数、名词单复数以及一般疑问句的构成。
第一空：There be 句型遵循就近原则，最近的名词是 a big potato（单数），所以填 is，不能因为后面有 five red tomatoes 就用 are。
第二空：carrots 是复数，指示代词要用 these，不能用 this。
第三空：sheep 单复数同形，three sheep 不能写成 sheeps。
第四空：two 后接可数名词复数，hen 的复数是 hens。
第五、六空：those horses 是复数，一般疑问句用 Are 开头，否定回答是 No, they aren't。
易错点：① There be 就近原则判断错误，根据总数量误用 are；② sheep 误加 s 写成 sheeps；③ 复数名词漏写 s（如 hen）；④ 忘记句首字母大写；⑤ 否定答语误写成 No, they aren't 的漏写形式 No, they not。
6解答题
阅读下面的农场小短文，按要求完成后面的练习。
It is a sunny Saturday morning. Mike and his sister Amy are at Grandpa's farm. Look! The tomatoes are red and big. The carrots are orange. The potatoes are brown. Grandpa has many animals, too. There are six cows, four horses and ten sheep near the river. The sheep are white and fat. Some hens are walking here and there. Amy wants to pick some vegetables for lunch.
练习一：根据短文内容，回答下列问题。请注意句首字母大写，句末加标点。
1. What colour are the carrots?
2. How many horses are there on the farm?
3. Where are the sheep?
练习二：根据短文内容，判断下面的说法是否正确，正确写 T，错误写 F。
4. There are ten sheep near the river. ( )
5. The hens are flying in the sky. ( )
答案：1. They are orange. / The carrots are orange.
2. There are four horses. / Four.
3. They are near the river. / Near the river.
4. T
5. F
解析：本题考查四年级下册 At the farm 话题的阅读理解，属于基础题。第1题问颜色，短文第二句写 The carrots are orange，回答 They are orange. 或 The carrots are orange. 均可。第2题问数量，短文写 four horses，注意数字要用英文 four。第3题问地点，短文写 near the river。第4题短文明确写 ten sheep near the river，故正确。第5题短文只说 Some hens are walking here and there（母鸡在走来走去），并没有说在天上飞，故错误。易错点：①回答特殊疑问句只写单词而缺少完整句子，或句首不大写、句末不加句点；②看到 sheep 就想当然加 s，实际上 sheep 单复数同形，ten sheep 不写 sheeps；③第5题凭常识想象母鸡会飞，而不依据短文内容判断。
7解答题
农场里真热闹！请根据中文提示和括号内所给的词，完成下面的英语句子和对话。
一、用括号内所给词的适当形式填空。
1. Look! The little pigs __________ (roll) in the mud now.
2. This is __________ (Sarah and Amy) room. They share it.
3. We have a sports day __________ Friday morning. (填时间介词)
4. The farmer has five __________ (sheep) on the farm.
二、根据中文提示写出正确的英文句子，注意祈使句的用法。
5. 天要下雨了，请带上你的雨伞。(take, umbrella)
6. 请不要踩那些西红柿。(step on, tomatoes)
三、根据中文提示补全对话，每空一词。
7. —Are these __________ (西红柿)?
—Yes, __________ __________.
8. —Are __________ (那些) sheep?
—No, __________ __________. They are goats.
答案：1. are rolling
2. Sarah and Amy's
3. on
4. sheep
5. Take your umbrella, please. / Please take your umbrella.
6. Don't step on the tomatoes, please.
7. tomatoes; they are
8. those; they aren't
解析：本题综合考查 At the farm 话题与本册核心语法。第1题由 now 可知用现在进行时，结构为 be + 动词 -ing，主语 The little pigs 是复数，用 are，故填 are rolling，易错点是漏写 are 或把 rolling 写成 runing 式的错拼。第2题考查名词所有格，Sarah 和 Amy 共有一个房间，表示两者共同拥有，只在最后一个名词后加 's，故为 Sarah and Amy's；若写成 Sarah's and Amy's 则表示两人各有房间，与 They share it 矛盾。第3题考查时间介词，具体某天的上午用 on（on Friday morning），易错写成 in。第4题考查 sheep 单复数同形，five 后直接写 sheep，切勿加 s。第5、6题考查祈使句：祈使句以动词原形开头，不加主语 You，也不加三单形式 Takes，表示否定用 Don't + 动词原形，礼貌表达可在句末或句首加 please。第7、8题考查 Are these / Are those 的一般疑问句及其答语：these 指近处“这些”，those 指远处“那些”；名词要用复数 tomatoes（不是 tomatos）；肯定答语 Yes, they are.，否定答语 No, they aren't.，主语一律用 they，不能用 these/those。易错点是回答时误写成 Yes, these are. 或漏写 are。
8解答题
根据情境，完成下列任务。要求：句子首字母大写，注意名词单复数与标点符号。
今天是星期六，你在农场帮忙。请根据下面的信息，用英语回答问题。
已知信息：
· 这些：carrot（胡萝卜），数量 12 根，又脆又甜。
· 那些：sheep（绵羊），数量 5 只，很可爱，喜欢在草地上跑。
任务一：用 Are these 提问并回答这些胡萝卜（用肯定回答）。
任务二：用 Are those 提问并回答那些绵羊（用肯定回答）。
任务三：仿照例句描述绵羊的特征和喜好。例句：The ducklings are cute. They like to swim in the water.
答案：任务一：—Are these carrots? —Yes, they are.
任务二：—Are those sheep? —Yes, they are.
任务三：The sheep are cute. They like to run on the grass.（参考答案，句意通顺、句型正确即可）
解析：本题综合考查 Are these / Are those 一般疑问句及答语、名词复数和描述性句型。任务一：these 指近处的胡萝卜，问句为 Are these carrots? 肯定回答 Yes, they are.（不能用 Yes, it is，因为 these 是复数）。任务二：those 指远处的绵羊，问句为 Are those sheep? 肯定回答 Yes, they are. 任务三：用「主语 + be + 形容词」描述特征，用「主语 + like to + 动词原形」描述喜好，如 The sheep are cute. They like to run on the grass.
易错点：一是复数名词忘记加 s，写成 Are these carrot?；二是 sheep 单复数同形，误写成 sheeps；三是答语主语误用 it，应为 they；四是句首首字母未大写或句末漏问号、句号；五是把 cute 误写成 cutely，或把 like to run 写成 like running（四年级阶段优先用 like to + 动词原形）。
