實(shí)驗(yàn)室用銅制取硫酸銅，將適量硝酸分多次加入到銅粉與稀硫酸的混合物中，加熱使之反應(yīng)完全，通過蒸發(fā)、結(jié)晶得到硫酸銅晶體。
（1）為了節(jié)約原料，硫酸和硝酸的物質(zhì)的量之比最佳為：    ；為了吸收該反應(yīng)中產(chǎn)生的尾氣，請(qǐng)選擇下列中合適的裝置       。

（2）為符合綠色化學(xué)的要求，某研究性學(xué)習(xí)小組進(jìn)行如下設(shè)計(jì)：
第一組：以空氣為氧化劑法
方案1：以空氣為氧化劑。將銅粉在儀器B中反復(fù)灼燒，使銅與空氣充分反應(yīng)生成氧化銅，再將氧化銅與稀硫酸反應(yīng)。
方案2：將空氣或氧氣直接通入到銅粉與稀硫酸的混合物中，發(fā)現(xiàn)在常溫下幾乎不反應(yīng)。向反應(yīng)液中加少量FeSO4，即發(fā)生反應(yīng)，生成硫酸銅。反應(yīng)完全后，加物質(zhì)甲調(diào)節(jié)pH ，鐵元素全部沉淀（一般認(rèn)為鐵離子的濃度下降到10-5mol·L-1，就認(rèn)為沉淀完全），然后過濾、濃縮、結(jié)晶。
已知：Ksp[Cu((OH)2]≈10-22， Ksp[Fe((OH)2]≈10-16,  Ksp[Fe((OH)3]≈10-38
請(qǐng)回答下列問題：
如開始加入的銅粉為3.2 g，最后所得溶液為500 mL,溶液中含有鐵元素0.005 mol。
①方案1中的B儀器名稱是       。
②為了使鐵元素全部沉淀，應(yīng)調(diào)節(jié)pH至少為_________。
③方案2中甲物質(zhì)可選用的是             。
A．CaOB．NaOHC．CuCO3D．Cu2(OH)2CO3 E、Fe2(SO4)3
④反應(yīng)中加入少量FeSO4可加速銅的氧化，用離子方程式解釋其原因        。
第二組：過氧化氫為氧化劑法
將3.2g銅絲放到45 mL 1.5mol·L-1的稀硫酸中，控溫在50℃。加入18mL 10%的H2O2，反應(yīng)0.5h，升溫到60℃，持續(xù)反應(yīng)1 h后，過濾、蒸發(fā)濃縮、減壓抽濾等，用少量95%的酒精淋洗后晾干，得CuSO4·5H2O 10.5g。
請(qǐng)回答下列問題：
⑤反應(yīng)時(shí)溫度控制在50℃~60℃不宜過高的原因是         ，
⑥本實(shí)驗(yàn)CuSO4·5H2O的產(chǎn)率為         。

科目：初中英語 來源：2012年初中畢業(yè)升學(xué)考試（廣東廣州卷）英語（帶解析） 題型：閱讀理解

Paul and Jason were brothers who lived and worked on neighbouring farms．For 35 years they farmed side by side，sharing machinery and goods as needed，without a single problem．
However，one autumn，things changed．It began with a tiny disagreement about a horse，which grew into a major difference．The difference led to angry words，followed by weeks of silence between the two brothers．
One morning there was a knock on Paul’s door．He opened it and saw a builder holding his toolbox．“I’m looking for a few days’work，”the builder said．“Are there any jobs here I could help with?”
“Yes，”answered Paul，extremely pleased to see the builder．“I do have a job for you．Look at that farm across the creek(小溪)．That’s my brother’s farm.That creek used to be a grass field，but last week my brother dug a path from the fiver and made the creek．But I’ll go him one better．See that pile of wood?1 want you to build me a fence，two metres tall，so 1 won’t need to see him anymore．”
The builder said thoughtfully．“I think I understand the situation and I'll be able to do a job that pleases you．”
Paul had business in town that day and left the builder to his work．When he returned，the builder had just finished his job．Paul was shocked．Instead of a fence there was a bridge，stretching from one side of the creek to the other．
As Paul stood on the bridge，staring in amazement，his younger brother Jason，came across，and took Paul’s hand．“You are a good man to have built this bridge after a11 I've done，”said Jason．
Then，Paul，with tears in his eyes，said to the builder who was packing his bag to go，“Thank you so much。Please stay．I have much more for you to do．”
“I’d love to．”the builder said quietly，“but，I have many more bridges to build.”
【小題1】What was the cause of the disagreement between the two brothers?

A．The digging of the creek．
B．A problem about a farm animal．
C．Who owned the field between the farms．
D．Who would pay for building the fence．
【小題2】The underlined expression“go him one better”in paragraph 4 means         ·
A．do something even worseB．improve the situation
C．point out his mistakeD．help him out
【小題3】What do we know about the brothers?
A．They had been fighting for many years．
B．Their farms were not very successful．
C．They finally realized their mistakes．
D．They liked building bridges．
【小題4】Why did the builder build the bridge?
A．He needed a way to get across the river．
B．There was not enough wood for the fence．
C．He misunderstood Paul’s instructions．
D．He wanted to bring the brothers together．
【小題5】In what order did the following take place in the story?
