it.全国三分之一的地方有震感。one-third三分之一，分数词的表示方法是：1.分数用基数词（one，two，three，.），分母用序数词（first，second，third，.），当分子大于1时，分母的词尾要加s。2.前面带有整数的分数用数字表示，但在句首时则用文字。three-fourths of the water is polluted and one-fourth of the villagers havemoved away.四分之三的水已经被污染，四分之一的村民已搬走。your bag is 2 1/2 times the weight of mine. 你的书包是我的书包的两倍重。two and a quarter inches of rain fell over the weekend. 周末的降雨量达2 1/4英寸。2、the number of people who were killed or injured reached more than 400,000.死伤人数达到40多万。the number of是“数字，数量”的意思，其后的谓语要用单数第三人称；a number of意为“很多，大量”，谓语要用复数。the number of students of our school is over 3000. 我们学校的学生数已达3000多人。a number of students have gone to america this summer. 今年暑假很多学生到美国去了。3、sand now filled the wells instead of water.井里满是沙子而不是水。instead of是短语介词，意为“代替”，其后常接名词、代词、动名词及介词短语等，而instead是副词，是“然而”“而不是”的意思，常位于句首或句末。使用时，有时二者可以转换。今天晚上我看电影，而不看电视。 1）ill see a film this evening instead of watching tv. 2）ill not watch tv this evening. ill see a film instead.他们通常步行上班，而不是乘公交汽车。 1）they usually go to work on foot instead of by bus. 2）they usually go to work on foot, but this time they will by bus instead.4、people began to wonder how long the disaster would last.人们开始纳闷这场灾难还会持续多久。last既可以用作形容词、副词，也可以用作不及物动词，不能用于被动语态。此处用作动词，是“持续，延续”的意思，它的含义比较广泛。the sports meet lasted three days. 运动会开了三天。the friendship between us will last long. 我们之间的友谊将天长地久。the weather lasted a whole week, which made everybody tired and sleepy. 暑热持续了一周，弄得人们疲惫困倦不堪。5、all hope was not lost.不是所有的希望都破灭了。all not .=not all 意为“并不是所有的都”，在英语中属于部分否定，not之后跟all，every，both等词时，是部分否定。not all the girls left early. =only some of the girls left early. 并不是所有的女孩都走得很早。dont throw rubbish everywhere. 不要到处乱扔垃圾。not every teacher is busy today. =some are busy, some arent busy.not both of my parents agree with me. 并不是我的父母都同意我的意见。两者都不用neither，两者以上的全部否定用none of .none of the teachers here smoke. 这儿的老师都不抽烟。neither of his parents is at home today. 他父母今天都不在家。6、they organized teams to dig out those trapped and to bury the dead.救援人员组成小分队，将受困的人们挖出来，将死者掩埋。the dead死难者，定冠词the之后加形容词，表示一类人。the old and the sick sat on a morecomfortable bus. 老人和病人坐在一辆舒服些的汽车上。for the blind, life is difficult. we should care for them whenever we can. 对盲人来说，生活是很艰难的，任何时候我们都要关心他们。语法：定语从句1.定语从句的两种结构：a.主句（先行词）+引导词+从句this is the pen that i bought yesterday. 这是我昨天买的那只钢笔。以上划直线部分为主句，其中pen为先行词，that为引导词，引导的斜体字部分为定语从句，整个定语从句修饰先行词pen。b.主句部分（先行词）+引导词+从句+主句部分the pen that i bought yesterday is made in japan. 我昨天买的那只钢笔是日本产的。a句型的特点是主句和从句前后两部分，而b句型的特点是主句被从句隔开。2.关系代词that，which，who引导的定语从句见课本p90-p91练习：now add an attributive clause to complete each sentence using that, which, who,or whose.the terrible shaking of the building woke up all the people who were asleep.the next day people put up shelters in the open air with all kinds of things that/which they could find.several days later most of the buildings

伤害；损害hurt vt. 使受伤；使伤害； vi. 疼痛这两个动词都有“伤害”的意思，injure是指意外事故中的受伤，hurt是指一般性的普通外伤。作不及物动词是“疼痛”的意思，指伤害某人的感情时，二者可以互换。five people were badly injured in the traffic accident. 有5人在车祸事故中严重受伤。be careful not to hurt your finger. 当心别把手指弄伤了。in the football match he hurt his leg and now it hurts badly. 在足球比赛中他的腿受伤了，现在（腿）痛得很。what you said at the meeting hurt/injured her pride（feelings）.
