【正文】 of requests for Chinese au pairs from zero to around 4,000 since that’s true all across the country.“I thought it wouls be very useful for him to learn Chinese at an early age,” Joseph Stocke, the managing director of a pany, says of his 2yearold son.“I would at least like to give him the chance to use the language in the futurre.” After only six months of being cared for by a 25yearold woman from China, the boy can already understand basic Chinese daily expressions, his dad Drake, a Chinese native raising two children in Minnesota with an American husband, had another reason for looking for an au pair from China: She didn’t want her children to miss out on their roots.“Because I am Chinese, my husband and I wanted the children to keep exposed to(接觸)the language and culture,” she says.“Staying with a native speaker is better for children than simply sitting in a classroom,” says Suzanne Flynn, a professor in language education of Children.“But parents must understand that just one year with au pair is unlikely to produce mastery demands continued learning until the age of 10 or 12.”The popularity of au pairs from china has been strengthened by the increasing numbers of American parents who want their children who want their children to learn is expected that American demand for au pairs will continue to rise in the next few does that term “au pair” in the text mean? mother raising her children on her child learning a foreign language at professor in language education of young foreign woman taking care of Drake has her children study Chinese because she wants them live in China some day speak the language at catch up with other children learn about the Chinese culture can we infer from the text? Chinese is being popular In woman do better in looking after au pairs need to improve their English can learn a foreign language well in six months.(D)Metro Pocket Guide地鐵)Earth passenger needs a farecard to enter and go to two children under age five may travel free with a paying machines are in every small bills because there are no change machines in the stations and farecard machines only provide up to $5 in one day of unlimited Metrorail rides with a One Day it from a farecard machine in Metro it after 9:30 closing on weekdays, and all day on weekends and : 5 .— .—: midnight Sun.— .—Last train times avoid missing the last train, please check the last train times posted paying with exact change, the fare is $ paying with a SmarTrip174。 more information about buying senior/disabled farecards, SmarTrip174。 Found at should you know about farecard machines? start selling tickets at 9:30 are connected to change offer special service to the make change for no more than $ what time does Metrolrail stop service on Saturday? 3 5 7 is good about a SmarTrip174。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。Joe Simpson and Simon Yates were the first people to climb the West Face of back conditions were very fell and broke his both knew that if and try to lower Joe down the mountain on a rope(繩).As they down, the weather got another couldn’t see or hear each other and, precipice(峭壁for Joe to climb back or for Simon to pull him ’s large crevasse(裂縫)in the ice had no food or water and he was in terrible couldn’t walk, but he , but he didn’t want to leave heard Joe’s couldn’t mistake chance choice luck back a rest a decision on for to for to 第II卷第二節(jié) 語法填空（共10小題；，滿分15分）閱讀下面材料，在空白處填入適當(dāng)?shù)膬?nèi)容(不多于3個(gè)單詞)或括號(hào)內(nèi)單詞的正確形式。文中共有10處語言錯(cuò)誤，每句中最多有兩處。增加：在缺詞處加一個(gè)漏字符號(hào)(∧)，并在其下面寫出該加的詞。修改：在錯(cuò)的詞下劃一橫線，并在該詞下面寫出修改后的詞。My dream school starts at 8:30 ends at 3:30 are three lessons in the morning and two in the didn’t need to do so many , we have more time with afterschool example, we can do reading for one and a half hour and play sports for one hour every dream school look like a big are all kinds of the flowers and trees around the classroom can lie on the grass for a rest, or sat by the lake listening teachers here are kind and are not only our teachers but also our 書面表達(dá)(滿分25分)一家英語報(bào)社向中學(xué)生征文，主題是“十年后的我”。⒈ 家庭；⒉ 工作；⒊ 業(yè)余生活。第二篇：普通高等學(xué)校招生全國(guó)統(tǒng)一考試化學(xué)卷普通高等學(xué)校招生全國(guó)統(tǒng)一考試化學(xué)卷第I卷〔選擇題，共72分〕可能用到的原子量：HCNONaMgSBa137一、選擇題〔此題包括8小題，每題4分，共32分?！?．水資源非常重要，聯(lián)合國(guó)確定2003年為國(guó)際淡水年。表示上述反響的熱化學(xué)方程式正確的選項(xiàng)是AC8H182〔g〕＝8CO2〔g〕＋9H2O〔g〕△H＝－mol－1CC8H182〔g〕＝8CO2〔g〕＋9H2O〔1〕△H＝＋5518kJmol－15．同溫同壓下，在3支相同體積的試管中分別充有等體積混合的2種氣體，它們是①NO和NO2，②NO2和O2，③NH3和N2。那么溶質(zhì)的分子量〔相對(duì)分子質(zhì)量〕為ABCD7．在一定條件下，RO3n－和氟氣可發(fā)生如下反響：RO3n－＋F2＋2OH－＝RO4－＋2F－＋H2O。L－1和bmol每題只有一個(gè)或兩個(gè)選項(xiàng)符合題意。〕9．以下各分子中，所有原子都滿足最外層為8電子結(jié)構(gòu)的是AH2OBBF3CCCl4DPCl510．以下有關(guān)純鐵的描述正確的選項(xiàng)是A熔點(diǎn)比生鐵的低B與相同濃度的鹽酸反響生成氫氣的速率比生鐵的快C在潮濕空氣中比生鐵容易被腐蝕D在冷的濃硫酸中可鈍化11．假設(shè)溶液中由水電離產(chǎn)生的c〔OH－〕＝110－14mol以下說法正確的選項(xiàng)是A甲燒杯中放入鋅的質(zhì)量比乙燒杯中放入鋅的質(zhì)量大B甲燒杯中的酸過量C兩燒杯中參加反響的鋅等量D反響開始后乙燒杯中的c〔H＋〕始終比甲燒杯中的c〔H＋〕小18．將L－1的NaOH溶液等體積混合后，溶液顯堿性，以下關(guān)系式中正確的選項(xiàng)是Ac(HCN)＜c(CN－)Bc(Na＋)＞c(CN－)Cc(HCN)－c(CN－)＝c(OH－)Dc(HCN)＋c(CN－)＝在室溫較低時(shí)，無水乙酸就會(huì)凝結(jié)成像冰一樣的晶體。答：〔2〕要配制濃度約為2molA稱取8gNaOH固體，放入250mL燒杯中，用100mL量筒量取100mL蒸餾水，參加燒杯中，同時(shí)不斷攪拌至固體溶解B稱取8gNaOH固體，放入100mL量筒中，邊攪拌，邊慢慢參加蒸餾水，待固體完全溶解后用蒸餾水稀釋至100mLC稱取8gNaOH固體，放入100mL容量瓶中，參加適量蒸餾水，振蕩容量瓶使固體溶解，再參加水到刻度，蓋好瓶塞，反復(fù)搖勻D用100mL量筒量取40mL5mol氣體abcdC2H4乙醇濃H2SO4NaOH溶液濃H2SO4Cl2濃鹽酸MnO2NaOH溶液濃H2SO4NH3飽和NH4Cl溶液消石灰H2O固體NaOHNO稀HNO3銅屑H2OP2O5〔1〕上述方法中可以得到枯燥、純潔的氣體是。②氣體，理由是。④氣體，理由是。寫出這些化合物的化學(xué)式?！?〕單質(zhì)L是?！?〕圖中除反響①以外，還有兩個(gè)用于工業(yè)生產(chǎn)的反響，是和〔填代號(hào)〕。五、〔此題包括2小題，共18分〕23．〔10分〕A是一種含碳、氫、氧三種元素的有機(jī)化合物。請(qǐng)?zhí)羁眨骸?〕A的分子式是，其結(jié)構(gòu)簡(jiǎn)式是。〔3〕寫出所有滿足以下3個(gè)條件的A的同分異構(gòu)體的結(jié)構(gòu)簡(jiǎn)式。這些同分異構(gòu)體的結(jié)構(gòu)簡(jiǎn)式是。寫出A、B、C、D的結(jié)構(gòu)簡(jiǎn)式：六、〔此題包括2小題，共20分〕25．〔8分〕取一定量的Na2CONaHCO3和Na2SO4混合物與250mL，CO2〔標(biāo)準(zhǔn)狀況〕，然后參加500mLBa(OH)2溶液。26．〔12分〕I．恒溫、恒壓下，在一個(gè)可變?nèi)莘e的容器中發(fā)生如下發(fā)應(yīng)：A〔氣〕＋B〔氣〕C〔氣〕〔1〕假設(shè)開始時(shí)放入1molA和1molB，到達(dá)平衡后，生成amolC，這時(shí)A的物質(zhì)的量為mol。〔3〕假設(shè)開始時(shí)放入xmolA，2molB和1molC，到達(dá)平衡后，A和C的物質(zhì)的量分別是ymol和3amol，那么x＝mol，y＝mol?！?〕假設(shè)在〔3〕的平衡混合物中再參加3molC，待再次到達(dá)平衡后，C的物質(zhì)的量分?jǐn)?shù)是。〔5〕開始時(shí)放入1mo
