Unit 3 Same or Different期中考试复习 Grammar Focus 【语法知识整合】 比较级形式构成 1. 规则变化 构成方法 原级 比较级 一般直接加 -er, -est tall 以不发音的e结尾，加 -r, -st large 以“辅元辅”结尾，双写末尾字母再加 -er big 以“辅音字母+y”结尾，变y为i再加 -er happy 在词前加 more important 中考重点提醒： • 双写规则是高频考点，需牢记常见词：big, fat, thin, red, wet, sad, hot 等。 • 双音节词的变法易混：一般而言，以 -y, -er, -ow, -le 结尾的双音节词，多用 -er/-est（如: happy, clever, narrow, simple）。其他双音节词及所有多音节词，用 more/most（如: careful → more careful, famous → more famous）。 2. 不规则变化 中考重点提醒： • farther/further 和 older/elder 的辨析是常考点。 • less 和 least 是 little 的比较级和最高级，用于构成“劣等比较”，结构为 less + 原级 + than 和 the least + 原级 + of/in...。 Eg: The book is less interesting than that one. good/ well → __________ bad/badly/ill → __________ much/many → __________ little → __________ far → __________ old → __________ 比较级常用句型 1. “主语 + 谓语 + 比较级 + than + 对比成分”表示“……比……更……” • To keep healthy, we should eat more vegetables than meat. • The population of Shanghai is larger than that of Nanjing. • 比较对象的一致性：必须是同类事物相比。 (错) The weather in Beijing is colder than Shanghai. (天气 vs 城市) (对) The weather in Beijing is colder than that in Shanghai. (天气 vs 天气) 2. “the + 比较级 + of the two ... ”表示“两个中较……的” • Both inventions are useful, but the telephone is the more important of the two. • I have read both books, and I think the first one is the more interesting of the two. 3. “Which/ Who + 谓语 + 比较级，A or B?”表示“哪个/谁更……” • Which do you think is better for the environment, taking a bus or driving a car? • Who runs faster in your class, Lucy or Lily? 比较级特殊结构 4. “比较级 + and + 比较级”表示 “越来越……” • In spring, the days get longer and longer and the nights get shorter and shorter. • As the final exam is coming, our homework is becoming more and more. 5. “the 比较级...，the 比较级...”表示“越……，就越……” • The earlier you start, the more time you will have to review. • The more you practice your spoken English, the more confident you will feel. 6. “as +原级 + as”表示“两者在某一方面相同”；“not as + 原级 + as”表示“不如；不像……一样” • My best friend can run as fast as I (can). • The movie wasn't as/so interesting as the book. I was a little disappointed. 7. “比较级 + than any other + 单数名词”表示“比任何其他……都……” • Yao Ming was taller than any other player in his team. • Many people think that Shanghai is more modern than any other city in China. 比较级前的修饰词 比较级前可以用much a lot, far, a bit, a little, even等修饰词。 (中考重点提醒：very, quite, too, so 等词绝对不能修饰比较级。) • After a good sleep, I felt much / a lot better. • Could you please speak a little / a bit slower? I can't follow you. • The new movie is far more exciting than I expected. You really shouldn't miss it. •  It's cold today, but the weather report says it will be even colder tomorrow. 【基础过关】 I. 单项选择 (共10题，每题1分) 从A、B、C、D四个选项中，选出可以填入空白处的最佳答案。 1.

Everyone needs a friend who understands and accepts them for who they are. My two best friends, Tom and Jack, are both important to me, but in different ways. Tom is as outgoing as I am. We both enjoy going to parties and meeting new people. We can talk for hours about everything. He always makes me laugh. With Tom, I feel free and happy. We share similar views on life, so we hardly ever argue. Jack is different from both Tom and me. He is much quieter and more serious. He likes staying home and reading books. At first, we didn't think we could be friends. But one day, I failed a math test and felt really sad. Tom tried to cheer me up by telling jokes, but it didn't work. Jack came to me, didn't say much, but helped me with my math problems patiently. That day, I learned that a true friend isn't always the one who makes you laugh, but the one who is there for you when you need help. Now, I enjoy my time with both of them. From Tom, I learn to be more social and positive. From Jack, I learn to be more careful and hard-working. They both help me to become a better person. ( ) 11. What is the writer like? A.

Here are some opinions from three students. Wang Lei (13 years old): For me, a good friend is like a mirror. He should be similar to me. My best friend, Lin Tao, and I both like basketball and computer games. We often spend time together after school. I feel happy when I am with someone who understands my interests. Liu Ying (14 years old): I don't completely agree. I think differences are more important. My best friend is much taller and more athletic than me. She is also funnier. She teaches me how to play tennis and always makes me laugh. I think she helps me to see a wider world. Zhang Wei (13 years old): For me, the most important thing in a friend is not similarity or difference, but a kind heart. A good friend cares about you. He is there to help you when you are in trouble. He listens to you when you are sad. My friend isn't as smart as me in study, and he isn't as funny as Liu Ying's friend, but he is the most reliable (可靠的) person I know. 15. According to Wang Lei, what is a good friend like?
