E　【解析】根据后一句"Its leaves are turning yellow."（它的叶子变黄了），说明Wu Binbin看到了那棵小树，选E"Look at that little tree!"。 2. A　【解析】Wu Binbin说叶子变黄了，Chen Jie应该问"它怎么了？"，选A"What's wrong with it?"。 3. C　【解析】Wu Binbin说"Maybe it is thirsty."（也许它渴了），Chen Jie表示同意并补充说明，选C"It needs water and sun."（它需要水和阳光）。 4. D　【解析】问句"What should we do?"（我们该怎么办？）回答应该做的事情，选D"We should water it every day."（我们应该每天给它浇水）。 【多余选项】B. Do you like plants?　【解析】本对话围绕“植物生病了怎么办”展开，没有讨论是否喜欢植物，故为多余干扰项。 三、阅读理解 A篇：1. A　【解析】海报标题"How to Help Plants Grow?"直接点明主题，选A"怎样种好植物"。 2. B　【解析】海报第二条"Water them every 2 days."（每两天浇一次水），选B。 3. C　【解析】海报说"Put them in the sun."（放在阳光下）是对植物好的行为。pull leaves（摘叶子）和pick flowers（摘花）都是不好的行为。 4. C　【解析】植物需要sun、water、air，不需要toys（玩具），选C。 B篇：1. Zoom plants a tomato (plant). / A tomato. 【解析】根据第一句"Zoom wants to grow a tomato plant."可知Zoom种的是番茄。 2. Because Zoom forgets to water it. / Because it doesn't have water. 【解析】根据"But one day, Zoom forgets to water it. The plant turns yellow."可知植物变黄是因为Zoom忘记浇水了。 四、任务型阅读 ① sun　【解析】原文"Plants need three things to grow: sun, air and water." ② air　【解析】同上，植物生长三要素之一。 ③ water　【解析】同上，植物生长三要素之一。 ④ water　【解析】原文"We can water the flowers."，我们可以给花浇水。 【解析】本题考查从短文中提取关键信息的能力。植物生长三要素sun/air/water是Unit 4 Part B的核心知识点。 五、书面表达 参考范文： Hello! I like apples. They are red and sweet. I can water the flowers every day. I can plant trees in spring. Plants need sun, air and water. I am a good plant guard! 【解析】本题为开放性写作，重点考查学生能否用本单元核心句型表达对水果的喜好和对植物的关爱。只要使用了单元核心词汇和基本句型，语句通顺即可给分。 学科网（北京）股份有限公司 $
