I’m lying on my back in my grandfather’s orchard (果园), looking up at the branches above me. It is one of the last days of summer. Already the days are shorter and the nights are cooler. Some kinds of apples are already ripe(成熟的). Others will be ready to pick soon. I think of my grandmother’s apple pie, and how I used to make it with her. She died last year, before the apple harvest, and I have not had her pie since then. I really miss her. I hear bees busily humming about, visiting the late summer flowers. The gentle hum of their wings nearly sends me to sleep.

The sky is as blue as my grandfather’s eyes. Above me, big white clouds ran across the sky like pieces of cotton blowing in the wind. School starts in another week, and time seems to have slowed down.

“Sophie!” calls my grandfather. “Is that you?” I stand up, take his hand, and tell him all about my day as we walk through the orchard. We talk about apples, and bees and Grandma. He tells me that he misses her too.

He puts his rough, brown farmer’s hand around my shoulder and pulls me close. “ You know, Sophie,” he says, “ I spent the morning in the attic (阁楼), and you’ll never guess what I found. It’s the recipe(烹饪法) for Grandma’s apple pie. I used to help her make it sometimes. I can’t do it all alone, but you used to help her too. Maybe between the two of us, we can work it out. Want to try?”

“ But it won’t be the same without Grandma,” I tell him.

“That’s true,” he says, “but nothing is the same without Grandma. Still, I don’t think that she would want us never to have another apple pie. What do you say?” I nod yes, and we walk towards home…toward an afternoon in the farmhouse kitchen, making Grandma’s famous apple pie.

Computers are very important to modern life. Many people think that in the future we will use computers in everyday life. It is thought that we won’t have to go shopping because we will be able to get most things which are sold in shops on the Internet. There will be no more books because we will be able to get all texts from computers. People will use the Internet to play games, see films and buy food. Also,we can use the Internet to make telephone calls.

Some people are glad about these new ways of shopping and communication (交际). Others do not think that computers will replace our old ways.

Let’s look at books, for example. Some people think that one day we will not read books made of paper. Instead, we will buy and read books using computers. We’ll read texts on small pocket computers. The computers will keep many different books in them at the same time. We won’t need to turn to lots of pages and we will save lots of paper. We will use more and more computerized (计算机化的) books

Is Internet shopping such a pleasure(愉快的事) as going to the shop? Many people say it is not. It is a pleasure to go into shops and look at things you want to buy. It is also unlikely (不大可能) that many people will want to read large texts on our computers, because paper books may be more friendly. Maybe computers won’t change these two habits .

1.In the future , people will use computers for ___.

A．playing games, shopping and making telephone calls

B．making telephone calls, having meals and seeing films

C．seeing films, buying food and going for holidays

D．playing games, making telephone calls and seeing the doctors

2.In the passage, the word “replace” means ___.

A．更新

B．取代

C．交换

D．放弃

3.Which reason for using computerized books is not said in the passage?

A．Computerized books won’t be very expensive.

B．Computers can keep many different books in them.

C．We won’t have lots of pages.

D．We won’t need any paper.

4.It tells us _________ in the last paragraph

A．about the old and new ways of shopping and communicating

B．if the Internet will change our habits

C．about computerized books

D．about future uses of computers

5.The title for this passage is ___.

A．Computers will replace shops and books

B．Computers are the future

C．Computers will do everything for man

D．How computers change our life

实验室用铜制取硫酸铜，将适量硝酸分多次加入到铜粉与稀硫酸的混合物中，加热使之反应完全，通过蒸发、结晶得到硫酸铜晶体。
（1）为了节约原料，硫酸和硝酸的物质的量之比最佳为：    ；为了吸收该反应中产生的尾气，请选择下列中合适的装置       。

（2）为符合绿色化学的要求，某研究性学习小组进行如下设计：
第一组：以空气为氧化剂法
方案1：以空气为氧化剂。将铜粉在仪器B中反复灼烧，使铜与空气充分反应生成氧化铜，再将氧化铜与稀硫酸反应。
方案2：将空气或氧气直接通入到铜粉与稀硫酸的混合物中，发现在常温下几乎不反应。向反应液中加少量FeSO₄，即发生反应，生成硫酸铜。反应完全后，加物质甲调节pH ，铁元素全部沉淀（一般认为铁离子的浓度下降到10^-5mol·L^-1，就认为沉淀完全），然后过滤、浓缩、结晶。
已知：K_sp[Cu((OH)₂]≈10^-22， K_sp[Fe((OH)₂]≈10^-16,  K_sp[Fe((OH)₃]≈10^-38
请回答下列问题：
如开始加入的铜粉为3.2 g，最后所得溶液为500 mL,溶液中含有铁元素0.005 mol。
①方案1中的B仪器名称是       。
②为了使铁元素全部沉淀，应调节pH至少为_________。
③方案2中甲物质可选用的是             。

A．CaO

B．NaOH

C．CuCO3

D．Cu2(OH)2CO3 E、Fe2(SO4)3

④反应中加入少量FeSO₄可加速铜的氧化，用离子方程式解释其原因        。
第二组：过氧化氢为氧化剂法
将3.2g铜丝放到45 mL 1.5mol·L^-1的稀硫酸中，控温在50℃。加入18mL 10%的H₂O₂，反应0.5h，升温到60℃，持续反应1 h后，过滤、蒸发浓缩、减压抽滤等，用少量95%的酒精淋洗后晾干，得CuSO₄·5H₂O 10.5g。
