After lunch, John and Anna go to watch the little pigs. 9 many pigs are there? John 10 (count) first. One, two, … five pigs. Then Anna finds another pig behind a tree. They look very happy. John and Anna play with the pigs. 【答案】1．their 2．on 3．and 4．trees 5．to see 6．the 7．are 8．goes 9．How 10．counts 【导语】本篇是记叙文，主要讲述约翰和安娜兄妹周日去叔叔的农场游玩，体验农场生活的故事。 【详解】1．句意：这个星期天他们去参观他们叔叔的农场。 空格修饰名词所有格uncle’s farm，需要形容词性物主代词作定语，词形变化推导：人称代词they转换为形容词性物主代词their。 2．句意：农场里有各种各样的动物。 on the farm为固定介词搭配，表示 “在农场”，填写介词on。 3．句意：他们在那里看见兔子、鸭子、鸡、猪和奶牛。 多个并列名词列举，最后两项之间要用并列连词，填写并列连词and。 4．句意：农场里还有鲜花、果树和蔬菜作物。 and连接并列名词，flowers与plants均为复数形式，tree需要使用复数，名词tree变为复数trees。 5．句意：约翰和安娜很高兴看见这些动植物。 be happy后面接动词不定式作状语，固定结构be happy to do sth.，动词see变化为不定式to see。 6．句意：在早上，约翰用胡萝卜喂兔子。 in the morning是固定短语，表示“在早上”，应用定冠词the。 7．句意：这些白色的兔子十分可爱。 主语The white rabbits是复数，全文为一般现在时，be动词要匹配复数主语，be动词选用are。 8．句意：安娜去采摘一些水果和蔬菜当作午饭。 主语Anna属于第三人称单数，时态为一般现在时，谓语动词要做三单变化，动词go变为第三人称单数goes。 9．句意：有多少头猪？ 对可数名词的数量提问，使用疑问词组how many，句首首字母大写，填写疑问词How。 10．句意：约翰先数一数。 主语John属于第三人称单数，时态为一般现在时，谓语动词要做三单变化，动词count变为第三人称单数counts。 八．选词填空 阅读短文，从方框中选择适当的词并用其正确形式填空，使短文通顺、意思完整。每空限填一词，每词限用一次。 of    important    warm    we    animal    even    keep    but    forest    give Nature is full of wonders. In our world, there are many kinds of 1 and plants. They grow in different places—some in 2 , some even in rivers. Some plants are tall, like trees. Some are short, like grass. Others are small, such as flowers. Some plants need plenty 3 water, but others can live with very little water. Many people like 4 plants at home. Green plants make our world beautiful. Sunflowers turn to the sun to get light. They love 5 weather and they need sunlight, water and air to grow well. Some plants, like daisies (雏菊), are simple but pretty. They don’t grow tall, 6 they can bloom beautifully. Trees provide shade (提供阴凉) with their leaves. Many plants are helpful to people, like 7 us fruit and vegetables. 8 trees can be used (被用来) to build houses. Flowers make the air fresh and make people happy. Most plants are 9 to us. They are 10 friends. Let’s protect them from now. 【答案】1．animals 2．forests 3．of 4．keeping 5．warm 6．but 7．giving 8．Even 9．important 10．our 【导语】本文介绍了自然界中各种植物的生长环境、习性特点及其对人类的重要作用，呼吁人们保护植物。 【详解】1．句意：在我们的世界里，有许多种类的动物和植物。此处需要一个名词复数，在句中表示与植物并列的生物类别。因为“many kinds of”后需接名词，且与“plants”构成并列关系，方框中只有“animal”符合语境，需变为复数形式表示泛指，所以填写“animals”。 2．句意：它们生长在不同的地方——有些在森林里，有些甚至在河里。此处需要一个名词复数，在句中表示植物生长的具体地点。因为前文提到“different places”，后文“rivers”也是地点，方框中“forest”符合语境，需用复数形式表示泛指，所以填写“forests”。 3．句意：有些植物需要大量的水，但另一些可以用很少的水生存。此处需要一个介词，在句中构成固定搭配表示“大量的”。因为“plenty of”是固定短语，用来修饰不可数名词“water”，所以选择“of”。 4．句意：许多人喜欢在家里养植物。此处需要一个动名词，在句中作“like”的宾语表示“种植/饲养”。因为“like doing sth.”是固定用法，表示喜欢做某事，“keep plants”意为“养植物”，所以填写“keeping”。 5．句意：它们喜欢温暖的天气，并且需要阳光、水和空气才能生长良好。此处需要一个形容词，在句中修饰“weather”表示“天气特征”。因为向日葵向太阳生长，需要充足阳光，可推断喜欢“温暖的”天气，所以选择“warm”。 6．句意：它们长得不高，但能开出美丽的花。此处需要一个连词，在句中表示转折关系。因为前文“don’t grow tall”与后文“can bloom beautifully”形成语义上的转折对比，所以选择“but”。 7．句意：许多植物对人们有帮助，比如给我们水果和蔬菜。此处需要一个动名词，在句中作介词“like”的宾语表示“给予”。因为“like”在此处是介词，后接动名词形式，“give sb. sth.”表示给某人某物，所以填写“giving”。 8．句意：甚至树木可以被用来建造房屋。此处需要一个副词，在句中表示递进关系。因为前文提到植物给人们提供水果蔬菜，此处进一步举例说明树木可用来建房子，表示递进，且位于句首需大写，所以填写“Even”。 9．句意：大多数植物对我们很重要。此处需要一个形容词，在句中作表语表示“重要的”。因为“be important to sb.”是固定搭配，表示“对某人很重要”，且前文列举了植物的各种用途，正是在说明其重要性，所以选择“important”。 10．句意：它们是我们的朋友。此处需要一个形容词性物主代词，在句中修饰“friends”表示所属关系。因为名词“friends”前需用形容词性物主代词，方框中“we”需变为形容词性物主代词“our”。 九．写作 众所周知，植物对于人类、动物和生态环境而言至关重要。你校英文杂志正在举办以“The importance of plants”为主题的征文大赛。假如你是李华，请你根据以下要点写一篇英语短文参加征文比赛，谈谈植物的重要性并呼吁大家爱护花草树木。 要点： For humans Give us food Produce oxygen For animals Eat the fruits Live in the forests For the environment Clean the air reduce the wind 要求：1. 短文须包含所有要点，可适当增加细节，使行文连贯； 2. 文中不得出现真实姓名和学校名称； 3. 词数不少于70（开头已给出，不计入总词数）。 The importance of plants As we all know, plants are very important for humans, animals and the environment. Now, let me _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】One possible version: The importance of plants As we all know, plants are very important for humans, animals and the environment. Now, let me tell you the importance of plants. For humans, plants give us food. We eat many fruits and vegetables from plants. They also produce oxygen for us to breathe. For animals, plants are useful too. Some animals eat plant fruits. Many animals live in the forests and make them their homes. For the environment, plants not only clean the air but also reduce the strong wind and protect the soil. So let’s protect plants. They are our good friends. We can’t live without them. 【详解】[总体分析] ①题材：本文是一篇说明文，为材料作文； ②时态：以“一般现在时”为主； ③提示：写作要点已给出，考生注意不要遗漏要点，并适当添加细节，突出重点。 [写作步骤] 第一步，引出主题，点明植物的重要性，自然引出下文； 第二步，分别从人类、动物、环境三个角度，阐述植物的作用； 第三步，呼吁大家保护植物，强调植物是人类的好朋友，人类离不开植物。 [亮点词汇] ①be important for对……重要 ②produce oxygen产生氧气 ③clean the air净化空气 ④reduce the strong wind减弱强风 ⑤protect the soil保护土壤 [高分句型] For the environment, plants not only clean the air but also reduce the strong wind and protect the soil.（not only...but also...句型） 1 学科网（北京）股份有限公司 $
