①attack vt.& vi. 攻击,进攻If yu are nt careful, a tiger will attack yu.你如果不小心, 老虎会攻击你。
中考在线1:人不犯我,我不犯人。We will nt _________ thers unless we ___________.【点拨】本题用词语运用法。attack 意为“攻击,进攻”,从句主语we 和 attack 有被动关系,应用被动语态。
attack are attacked
②unless yu take yur wn fd with yu.
take sth. with sb. 某人随身携带某物
辨析: take,bring,carry 与fetch
Please take a map with yu when yu travel.当你旅行的时候, 请随身携带一张地图。Culd yu help me t take the bx t the classrm?你能帮我把这个盒子拿到教室吗?
Bring me a cup f tea, please. 请给我拿杯茶。Let me carry this bag fr yu. 让我替你扛这只袋子吧。She’s gne t fetch the kids frm schl. 她去学校接孩子了。
中考在线2:A strng wind will arrive in Harbin. It will _________ much rain here.A. bring B. take C. catch D. fetch【点拨】bring 带来;take 带去;catch 抓住;fetch 去拿来。
中考在线3:—Tm, ________ the umbrella with yu. Lk at the dark sky. It’s ging t rain.—Thank yu, Dad. take B. wear C. use D. make
【点拨】考查动词辨析。句意:—汤姆,你带着把雨伞吧。看看这阴暗的天空。要下雨了。—谢谢你,爸爸。take 拿,买,花费;wear 穿,戴;use 使用;make 制作,使。take sth. with sb.“某人随身携带某物”,为固定搭配,故选A。
条件状语从句表示主句动作发生的条件, 在初中阶段常由if(如果) 引导, 表示“假如有从句的动作发生,就会有主句的动作发生”。Please call me if he is at hme.假如他在家的话, 请给我打电话。
if 引导的条件状语从句
[重点]时态如果主句是一般将来时, 从句一般用一般现在时。I wn’t g there with yu if it rains tmrrw.如果明天下雨的话, 我就不和你一起去那儿了。
中考在线1:If yu take this train, yu ______ in Shanghai in five hurs. A. arrive B. will arrive C. arrived D. have arrived【点拨】本题用语法判定法。考查动词时态。句意:如果你坐这班火车,你将在五小时内到达上海。分析句子结构可知,本题是含有if 引导条件状语从句的复合句,时态上遵循“主将从现”的原则。故选B。
主从句的位置从句可以位于主句之前, 也可以位于主句之后。不过从句在前时, 主从句之间须用逗号隔开。Please tell me if he cmes back.= If he cmes back, please tell me.如果他回来了, 请告诉我一声。
[易错点]if 的两面性if 引导条件状语从句时意为“如果”, 如果引导宾语从句则意为“是否”。请比较:(1)We will g ut if it is fine tmrrw.(2)I dn’t knw if the train has arrived.
中考在线2:— Wuld yu like t g hiking if it ________ fine this Saturday? — I’d lve t. But nbdy knws if it _______.A. is; will rain B. is; rainsC. will be; will rain D. will be; rains
【点拨】本题用语法判定法。考查动词时态。第一个if 意为“如果”,引导条件状语从句,从句中应用一般现在时表示将要发生的动作;第二个if 意为“是否”,引导宾语从句,主句中的谓语动词用一般现在时,宾语从句中可根据需要用任何时态,此处指这个星期六的天气,用一般将来时,故选A。
拓展:条件状语从句和主句还有一个共同的伙伴,有时它可以替代从句和主句,它就是“祈使句+and/r+ 简单句 ”。其中and 表示句意顺承;r 则表示转折,意为“否则”。
If yu wrk harder, yu’ll pass the exam.= Wrk harder, and yu’ll pass the exam.如果你再努力些,你就会通过考试。
中考在线3:Keep wrking hard, and yu will achieve success. (保持句意不变)___________ __________ keep wrking hard, yu will achieve success. [上海]【点拨】原句意为“继续努力,你就会成功的”,由句意可知,成功的条件是“继续努力”,将其转化为if 引导的条件状语从句,人称保持一致。if 放在前,后加 yu。故填If yu。
If yu
unless 引导条件状语从句, 相当于if 引导的条件状语从句的否定形式,即unless=。中文意为“如果不……;除非”。
unless 引导的条件状语从句
含unless 或if 引导的条件状语从句的复合句中,主句用一般将来时,从句用一般现在时代替一般将来时。即所谓的“主将从现”。
中考在线4:She says that she’ll have t clse the restaurant ________ business imprves. A. if B. after C. unless D. when【点拨】本题用句意理解法。考查连词的用法。句意:她说除非生意好转,否则她将不得不关闭这家餐馆。if 如果;after 在……之后;unless 除非;when 当……时候。由句意可知选C。
“祈使句( 肯定式)+r+ 陈述句”与“unless条件句+ 主句”有时可以相互转换。Put n yur raincat, r yu’ll get wet.=Unless yu put n yur raincat, yu’ll get wet.=If yu dn’t put n yur raincat, yu’ll get wet. 穿上雨衣,否则你会淋湿的。
中考在线5:Yu needn’t take an umbrella unless it rains tmrrw.(同义句转换)Yu needn’t take an umbrella __________ it __________ rain tmrrw.【点拨】本题用句式分析法。unless 意为“除非”,相当于if…nt。
拓展(1)unless 引导出补充前言的句子,即对刚说过的话进行补充。Let’s play chess—unless yu really have smething urgent t d.咱们下国际象棋吧—除非你真有急事要办。
(2)unless 在以下情况不能与 替换。①当某种条件所引起的结果是一种情绪或想法时,不能使用unless,只能用。I will be angry if I am nt invited t the party.如果我不被邀请参加这个聚会的话,我将会生气。
② 可以引导一个虚拟条件句,unless 一般不引导虚拟条件句。If she weren’t s silly, she wuld understand it.如果她不那么傻,她就会明白它的。
一、用所给单词的适当形式填空1. Wrk ut what yu need ___________(d) first, and g fr it tday.2. We dn’t have anther chance ___________________ (take) a hliday this year.3. As a student, I have little time ___________ (watch) news prgrammes n TV.
t take/ f taking
4. Nbdy can be successful unless he __________(lve) his wrk.5. If I have a gd day, I ___________ (be) prud f myself.
二、单项选择6. Vivian will take her daughter t the amusement park ________ she gets the tickets. if B. until C. althugh D. unless
【点拨】本题用句意理解法。考查连词辨析。句意:如果维维安弄到票,她会带她的女儿去游乐园。if 如果,引导条件状语从句;until 直到……为止,引导时间状语从句; althugh 尽管,引导让步状语从句;unless除非,如果不,引导条件状语从句。由句意可知选A。
7. Kitty, yu’ll fail the English exam ________ yu study hard. because B. when C. if D. unless【点拨】考查连词的用法。句意:基蒂,如果你不努力学习,你英语考试就会不及格。表示“如果不”用连词 unless,故选D。
8. —Jeff, culd yu tell me if it ________ tmrrw? If it ________ tmrrw, I will stay at hme.—It’s reprted that it will be sunny. Let’s g camping n the Fenghuang Muntain. A. rain; rain B. rains; rainC. will rain; rains D. will rain; will rain
【点拨】本题用语法判定法。考查动词时态。句意:——杰夫,你能告诉我明天有雨吗?如果有雨,我就待在家里。—据报道天气晴朗。我们去凤凰山露营吧。第一句if 引导宾语从句,由tmrrw 可知,用将来时;后句if引导条件状语从句,要用一般现在时表示将来,故选C。
9. —Will yu g t Lisa’s huse-warming party next Sunday?—Well, if I ________, I will g n time. A. invite B. will inviteC. am invited D. will be invited
【点拨】本题用语法判定法。句意:—下星期天你会去丽莎的乔迁派对吗?—唔,如果我被邀请,我会准时去的。由语境可知,主语I 和动词invite 之间是被动关系,表示“被邀请”,因此用被动语态;if 引导的条件状语从句,遵循主将从现的原则,主句为一般将来时,从句为一般现在时,因此从句用一般现在时的被动语态。故选C。
10. —I’m afraid we can’t wrk ut the math prblem ________ the teacher helps us.—That’s true. It’s t difficult. if B. unless C. because D. as sn as
【点拨】本题用句意理解法。if 如果;是否;unless 除非,如果不;because 因为;as sn as 一……就。由答语中“It’s t difficult( 它很难)”可知,老师帮助我们是计算出数学题的条件。由空格前“不能计算出那道数学题”可推知,空格处表达的是“如果不”。故选B。
三、同义词转换11. If yu dn’t hurry up, yu will be late.________ ________! ________ yu will be late.12. If there is n water, fish may die.Fish may ________ ________ water.
