(先行词是job) 他想找一份能将他的技能派上用场的工作。 [注意] 当先行词表示抽象的地点或带有地点的意味且在从句中充当类似于地点状语的作用时，定语从句用where引导。 单句语法填空 ①The accident has reached to the point ________ both their parents are to be called in. ②You would get into a situation ______ you have to decide immediately. ③The next day, my brother and I went to the beach _______ we watched some people play volleyball. ④Students should involve themselves in community activities ________ they can gain experience for growth. where where where where 3．why引导的定语从句 We didn't know the reason why he refused our help. 我们不知道他拒绝我们帮助的原因。 The mother can't accept the reason that/which the son gives for his absence from school. 这位母亲不能接受儿子为没上学给出的理由。 [注意] 先行词是reason时，定语从句的引导词需根据定语从句缺少的成分而定，如果缺少状语，用why；如果缺少主语或宾语，则用that/which。 单句语法填空 ①Unsuccessful people can always find reasons ______ they're not doing well. ②I don't believe the reason __________ he gave me for his being late. ③That was the reason __________ he gave for his absence. ④Do you know the reason ________ he didn't attend the meeting yesterday? why that/which that/which why 二、后缀 当我们的单词积累到一定词汇量的时候，通过前缀后缀的对比可以帮助我们理解记忆这些单词，比如通过构词法产生的新单词可以帮助背诵基本的单词，从而避免一些记了新单词而忘记老单词的情况。 有些英语单词由三部分组成，即：前缀、词根及后缀。单词中位于词根前面的部分就是前缀，位于词根后面的部分就是后缀。如：unacceptable中un是前缀，accept是词根，able是后缀。后缀词是指在一个词根的后面附加一个或几个字母构成的一个新词。如：snowy中y就是后缀。通常，后缀改变单词的词性，不改变词根的含义。 体会后缀的用法： reader 读者 inventor 发明家 Chinese 中国人 Indian 印度人 artist 艺术家 kindness 和蔼 operation 手术 这些单词是在各自的词根后加了不同的后缀，如­er, ­or, ­ese, ­ian等。 常见的后缀见下表： 分类 举例 名词后缀 ­er/­or(从事……的人)，­ese(某地人)，­ess(雌性)，­ian(……的人)，­ist(专业人员)，­ism(主义)，­ment(性质；状态)，­ness(性质)，­tion/­ation(动作；过程)，­dom(状态；区域) 动词后缀 ­en(多用于形容词之后)，­fy(使……化)，­ize(使……成为) 形容词后缀 ­al，­able，­an，­ble，­ern，­ful，­ive，­less，­like，­ly，­y，­ous，­some 副词后缀 ­ly(用于形容词后表示方式或程度)，­ward(s)(表示方向) 数词后缀 ­teen，­th，­ty 给下面单词加上适当的后缀。 1．nation________ adj. 民族的 2．reason________ adj. 合理的 3．north________ adv. 朝北 4．up________ adv. 向上 5．move________ n. 运动 6．dark________ n. 黑暗 7．inven________ n. 发明 8．real________ v. 意识到 al able ward ward(s) ment ness tion ize 主题写作 单元写作 灾难求生手册 一、常用表达 Ⅰ.体裁特点 28 Ⅱ.具体内容 Like many other natural disasters which have a serious influence on/upon people's life to ensure you can survive the flood When the rainy season is drawing near/approaching Stay away from dangerous floodwaters It is your safety that is the most important cause you to lose control of your vehicle 29 If you're indoors make sure look for the nearest shelter unless you're sure they're safe In case filled with Pay close attention to make adequate preparations in advance are trapped in stay/keep calm waiting for the rescue team to help 30 don't panic and keep calm use a wet towel to cover your mouth and nose don't take the lift as quickly as you can 31 二、微写作 假如你是李华，得知你的美国朋友Taylor所居住的城市将会有飓风， 你准备向他提供一些建议。内容要点如下： 1.向Taylor表示问候； 2.针对不同情况说明具体的应对措施。 注意:1.写作词数应为80左右； 2.可以适当增加细节，以使行文连贯。 32 Dear Taylor, I am really sorry to learn that a horrible hurricane will hit your city.
