2013屆高三大聯(lián)考一.ppt

大聯(lián)考一,表示“繼續(xù)保持或處于某種狀態(tài)”時(shí)，應(yīng)視具體情況在上述動(dòng)詞中進(jìn)行選擇： (1)表示“繼續(xù)保持或處于原來(lái)的狀態(tài)”時(shí)，可用remain或stay，例如： Three of them remained single. Shops should remain open till later in the evening. The door stayed closed. But the police themselves prefer to stay unarmed. (2)表示“需要設(shè)法才能保持或處于某種狀態(tài)”時(shí)，應(yīng)用keep，例如： She knew she must keep calm. I wish those children would keep quiet. Although they have many difficulties, they keep happy. Paul managed to keep awake by drinking lots of strong black coffee.,(3)表示“使某人或某物保持某種狀態(tài)”時(shí)，只能用及物動(dòng)詞keep，例如： She had kept him waiting twenty minutes on this occasion. Why do you always keep your windows closed?,1表示“繼續(xù)呆在某處”時(shí)，應(yīng)該用不及物動(dòng)詞remain或stay，例如： Shall I go or stay? Stay indoors for a few days until you recover from your cold. He remained in his seat after all the other students had gone home. 2表示“暫住、短期停留”時(shí)，只能用不及物動(dòng)詞stay。例如： He is staying at Hilton Hotel. My mother-in-law stayed with us this week when she visited us.,3表示“殘留、剩下”時(shí)，只能用不及物動(dòng)詞remain，例如： Not much of the house remained after the fire. Of the seven brothers, only four now remain; the rest are dead.,閱讀A篇Ausefuldefinitionofanairpollutantisacompoundaddeddirectlyorindirectlybyhumanstotheatmosphereinsuchquantitiesastoaffecthumans,animals，vegetation，ormaterialsnegatively (特殊結(jié)構(gòu)suchasto如此以致) 空氣污染物的一個(gè)有用定義是：一種直接或間接加入到空氣里的化合物，其數(shù)量足以對(duì)人類(lèi)、動(dòng)物、植物或物質(zhì)產(chǎn)生不利影響。,全文翻譯: 人類(lèi)直接或間接使大氣中一種化合物的含量增加，從而對(duì)人、動(dòng)物、植物或原料等產(chǎn)生了不利影響，這種化合物就叫做空氣污染物，這是對(duì)空氣污染物的有效定義?？諝馕廴镜亩x會(huì)繼續(xù)改變。當(dāng)?shù)谝徊拷箍諝馕廴镜姆稍?4世紀(jì)的英格蘭被制定出來(lái)時(shí)，空氣污染物還僅限于那些能夠被看到和聞到的復(fù)合物遠(yuǎn)少于我們今天所熟知的污染物的種類(lèi)。隨著技術(shù)發(fā)展、各種各樣化學(xué)物質(zhì)對(duì)健康的影響方面知識(shí)的增多，空氣污染物的種類(lèi)也在增多。在未來(lái)，即使是水蒸氣在某種條件下也有可能成為污染物。,有很多主要的空氣污染物，如硫化物、一氧化碳、氮氧化物在自然界中均可發(fā)現(xiàn)。隨著地球的發(fā)展，這些污染物的濃度被各種化學(xué)反應(yīng)影響而發(fā)生變化。它們成為了生化循環(huán)中的組成部分。同時(shí)，將這些混合物從空氣中轉(zhuǎn)移到水或土壤中也是空氣凈化的一項(xiàng)方案。在全球范圍內(nèi)，人類(lèi)活動(dòng)所產(chǎn)生的污染物遠(yuǎn)少于自然界產(chǎn)生的污染物。而人類(lèi)所制造的污染物通常出現(xiàn)在某一固定區(qū)域，比如某個(gè)城市。,在這樣的一個(gè)固定區(qū)域內(nèi)，人類(lèi)活動(dòng)產(chǎn)生的污染物隨時(shí)可能超出自然界消除污染物的凈化系統(tǒng)物的承載能力。結(jié)果使得空氣中有害化學(xué)物質(zhì)的濃度上升。一種物質(zhì)要成為污染物其濃度并不需要很大；實(shí)際上，數(shù)值并不能告訴我們什么，除非我們知道這個(gè)數(shù)值代表的增加量超過(guò)了該地區(qū)自然濃度多少。例如，硫氧化物在0.08ppm (百萬(wàn)分之0.08) 時(shí)就會(huì)對(duì)健康有影響，這是它自然水平的400倍；然而一氧化碳自然水平是0.1ppm，濃度只有達(dá)到15ppm才能成為污染物。,One possible version: Im Li Hua, a senior high school student from the Peoples Republic of China and Ill graduate next June. My grandfather graduated from Harvard University 35 years ago and Im interested in studying in Harvard Law School. Im wondering what the admission requirements for international applicants are.
