Firstly, homework for middle school students should take no more than 90 minutes. They can finish most of written homework at school so that after school they only spend a little time finishing the rest. Some students can still go to sleep on time even though they don’t finish their homework until bedtime. Then they will have more time to relax. Secondly, mobile phones mustn’t be brought to class because students are easily absent-minded (心不在焉的) from the lesson. Students must control the time on electronic products to protect their eyesight. They shouldn’t lose themselves in the Internet. Thirdly, students are expected to listen carefully and go over lessons in time so that they can master the right methods of learning. Fourthly, parents should often communicate with their children, pay attention to their feelings and help them develop good learning and life habits. In a word, these rules are helpful to middle school students. If they follow the rules, they can improve their study and health.(E8102004) 1.Why did our country carry out the rules? 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　  2.How long should homework for middle school students take? 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　  3.Mobile phones mustn’t be brought to class, must they? 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　  4.How can students master the right methods of learning according to the passage? 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　  　　　　　　　　　　　　　　　　　　　　　　　　　　　　　  5.How many rules are talked about in this passage? 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　  18 / 18 学科网（北京）股份有限公司 $$ 第04讲 Unit 2 School life（Grammar-Integration） （知识全梳理&考点精准练） 内容导航——预习三步曲 第一步：学 析教材 学知识：教材精讲精析、全方位预习 练习题 讲典例：教材习题学解题、快速掌握解题方法 练考点 强知识：核心考点精准练 第二步：记 串知识 识框架：学习目标复核内容掌握 第三步：测 过关测 稳提升：小试牛刀检测预习效果、查漏补缺快速提升 一．单词学习 1 aware [əˈweə(r)] adj.意识到，知道 2 be aware of 意识到 3 importance [ɪmˈpɔːtns] n.重要性 4 Japanese [ˌdʒæpəˈniːz] adj.日本（人）的，日语的 5 carefully ['keəfəlɪ] adv.仔细地；小心地 6 ourselves [ɑːrˈselvz] pron.我们自己 7 develop [dɪˈveləp] vt.形成vt.&vi.（使）发展 8 junior [ˈdʒuːniə(r)] adj.初级的；青少年的 9 rocket [ˈrɒkɪt] n.火箭 10 blog [blɒɡ] n.博客；网志 11 least [liːst] det.&pron.最少的adv.最少 12 Italian [ɪˈtæliən] adj.意大利（人）的，意大利语的 13 international [ˌɪntəˈnæʃnəl] adj.国际（化）的 14 vacation [veɪˈkeɪʃn , vəˈkeɪʃn] n.<美>假期，度假 15 textbook [ˈtekstbʊk] n.课本；教材 16 search [sɜːtʃ] vi.&vt.搜索；查找 17 finish [ˈfɪnɪʃ] vi.&vt.完成，做好 18 American [əˈmerɪkən] adj.美国（人）的 19 hamburger [ˈhæmbɜːɡə(r)] n.汉堡包 20 pizza [ˈpiːtsə] n.比萨饼 21 fried [fraid] adj.油炸的 22 salad [ˈsæləd] n.沙拉 23 chopstick [ˈtʃɒpstɪk] n.筷子 24 movie [ˈmuːvi] n.<美>电影 25 difference [ˈdɪfrəns] n.差异，不同（之处） 26 lunchtime [ˈlʌntʃtaɪm] n.午餐时间 27 cookie [ˈkʊki] n.<美>饼干 28 fork [fɔːk] n.餐叉 29 spoon [spuːn] n.勺，匙 30 boring [ˈbɔːrɪŋ] adj.没趣的，令人厌倦的 31 suggestion [səˈdʒestʃən] n.建议 32 facility [fəˈsɪləti] n.设施，设备 33 uniform [ˈjuːnɪfɔːm] n.校服，制服 34 improve [ɪmˈpruːv] vt.&vi.改进，改善 35 suggest [səˈdʒest] vt.建议 36 provide [prəˈvaɪd] vt.提供 37 moreover [mɔːrˈəʊvə(r)] adv.此外 38 yours sincerely 谨上，谨启 2． 课文解析 数量的比较 两者之间数量的比较 (1)more...than 结构表示"比……多",more后可接可数名词复数或不可数名词。 I have more storybooks than David. 我的故事书比戴维的多。 Peter has more milk than me.彼得的牛奶比我的多。 (2)fewer/less...than结构表示"比……少",可数名词复数用fewer修饰,不可数名词用less修饰。 Daniel studies fewer subjects than me.丹尼尔学的科目比我少。 Jane spends less money on snacks than you.简花在零食上的钱比你少。 as...as的用法 一．as...as与not as/so...as 用法 例句 当我们想表达"和……一样"时,常用"as + 形容词原级/副词原级+ as"结构。 This park is as large as that one.这个公园和那个公园一样大。 He studies as hard as his brother.他学习和他弟弟一样努力。 当我们想表达"和……不一样,不如/不及……"时,常用"not as/so + 形容词原级/副词原级+ as"结构。 I'm not as/so tall as him. 我没有他高。 二． not as/so...as与比较级结构之间的转换 　　"not as/so...as"结构意为 "不及,不如……",也可以用比较级结构来转换。 Cycling is not as/so dangerous as diving.=Cycling is less dangerous than diving.=Diving is more dangerous than cycling.骑自行车没有潜水危险。 Jim doesn't run as/so fast as my sister.=Jim runs more slowly than my sister.=My sister runs faster than Jim.吉姆没有我妹妹跑得快。 我在美国老家的学校和阳光中学很不一样。 我们班没有这里的大，每个班的学生也少。这里的学生在他们自己的教室里上大部分课。然而，我们通常去不同的教室上不同的课。他们不像我们一样经常换教室，所以他们与同学共度更多的时间，彼此更好地了解，但我们认识了更多的学生。 这里的学生大部分科目都有学生用书，但是我们只有少数科目有课本。我们经常需要从图书馆借书或者在网上搜索来完成作业。 三．知识梳理 考点1 have …off 有多长时间的假期 have …off (for …) （某个假期）休了多长时间的假 有 8 天时间的假。have eight days off= have an eight-day holiday off 相关短语： get off 下车 run off 迅速离开；跑 掉 put off 推迟；拖延 be off 离开，走开 take off 脱下；起飞 fall off 落下，从..掉下 go off 发出响声；离 开 show off 炫耀；卖弄 break off 突然中止；中 断 cut off 切断 keep off 远离；使...不踏 入 set off 激起；引起； 出发 考点2 need (1) need 作实义动词，意为“需要，必然” ，有人称、时态及数的变化。例如： need +sb./ sth. 需要某人/某物 to do sth. 需要做某事 doing 需要（被）做 (2) need 也可作情态动词，意为“需要，必须” ，没有人称、数和时态的变化，后接动词原 形，多用于否定句和疑问句中。 用 must 提问的句子，其否定回答常用 needn’t 。例如： — Must he hand in his homework this morning? 他必须今天上午交作业吗？ — No, he needn’t. 不，不必了。 【拓展】need to do 和 need doing 的辨析： need to do sth.意为“需要干某事” ，是自己主动去干某事； need doing 其主语是物，含有 被动的意义，相当于 need to be done 。例如： The student needs to do his homework as soon as he gets home. 那个学生需要一回家就做家庭作业。 My computer needs repairing. 我的电脑需要修理。 考点3 borrow v. 借来，借入 borrow sth from sb 从某人那借来某物 【辨析】 borrow, lend 与 keep “借 ”看执行者，“借出 ”或“借入 ”；“借出 ”用 lend,“借入 ”是 borrow 。如果用 keep，表示“借多久 ”。 borrow 从主语的角度讲是“借进” ，指从别人或别 处借东西，为非延续性动词。 borrow sth. from sb. /sp. 从某人/某处借某物 lend 从主语的角度讲是“借出” ，指把自己的东 西借给别人，为非延续性动词。 lend sb. sth. ＝ lend sth. to sb. 将某物借给某人 keep “借，保存，保持”，指借用某物一段时间， 为延续性动词。 keep sth. for some time 借用某物一段时间 考点4 四大花费 主语 动词 宾语 搭配 范例 sb. spend 时间/金钱 on sth.
