A Smart Home

When you’re not at home, many worries may start to crowd your mind. Did I turn the coffee maker off? Did I lock the door? Are the kids doing their homework or watching television? With a smart home, you can quiet all of these worries.

A smart home is a home with a communication network. This network connects devices(裝置), such as lights and TV sets, and allows them to be controlled from far away through electrical wiring, mobile phone communication or WiFi over the internet.

More and more people may start to consider owning a smart home, because it makes life much more convenient. It can help keep your room at a certain temperature. It can record what happens inside the home and send the video to your phone. When you are on vacation abroad, you can use a smart home controller to switch on or off the electricity when necessary. Some smart homes can receive a visitor, allowing him to come in and offering him a drink. They can even feed the cat and water the plants.

Besides, smart homes are easy to fix. Most smart home technology and devices are wireless and can be set up with a minimum of tools, using only the guiding information. When a problem appears, you can deal with it yourself without paying a professional.

However, for home-users, the smart home technology is far from perfect. It can be rather expensive to own the technology and the devices. Also, because the smart home system allow its owner to get home information from anywhere, it leaves the home easy to be attacked by hackers(黑客),who may secretly use or change the information in the system.

Now, many scientists are excited at the future of smart home technology. Imagine being able to get fashion advice from your mirror, or receive food shopping suggestions from your refrigerator. While there are others who worry that those smart devices will make people lazier and lonelier. Whatever it is, one thing is for sure---smart home technology will change the way we live and work.

1.According to the passage, nowadays a smart home can lock the door through______________.

A. electric lights B. mirror technologies

C. mobile phones D. shopping programs

2.The third paragraph of the passage is mainly about _________.

A. the steps to use smart systems

In the 13th century, the famous Italian traveler, Marco Polo, traveled a long way to China. During his stay in China, he saw many wonderful things. One of the things he discovered was that the Chinese used paper money. In western countries, people didn’t use paper money until 15th century. However, people in China began to use paper money in the 7th century.

A Chinese man called Cai Lun invented paper almost 2,000 years ago. He put these pieces of paper together and made them in a book.

Now paper comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. So how can we save paper? We can use both of every piece of paper, especially when we are making notes. We can choose drinks in bottles instead of those in paper packets(小包). We can also use handkerchiefs(手帕) and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give you a paper bag, we can save it and reuse it later.

Everyone can help to save paper. If we all think carefully, we can help protect trees. We should do it now, before it is too late.

1.When Marco Polo was in China, he _________.

A. discovered Cai Lun invented paper B. learned to make paper

C. discovered Chinese people used paper money D. learned to use paper money

2.People in Western countries first used paper money in the ________ century.

A. 17th B. 15th C. 13th D. 7th

3.Which of the following is NOT the way of saving paper?

A. To use both sides of every piece of paper.

B. To use the paper bags from shops more than once.

C. To use cotton handkerchiefs instead of paper ones.

D. To grow more trees.

4.Which of the following is not true?

A. If we keep on wasting paper, we will have no paper to use.

B. The Chinese people used paper money earlier than the people in Western countries.

C. .Chinese man called Cai Lun invented paper money about two thousand years ago.

D. We can use the paper bags from the shops again.

5.Which is the best title of the passage?

A. Saving Paper B. The History of Paper

C. Cotton Handkerchiefs Back Again D. Cai Lun Invented Paper

Hi Jake,

How’s it going? Sorry I haven't been in touch for a while, but couldn’t use my computer for a few days. You’ll never guess what happened to me!

A couple of weeks ago, I decided to take up yoga. Yoga is a combination of physical and breathing exercises. It's supposed to be good for relaxation and 1.. I've been feeling a

bit stressed about my school work recently and I thought yoga might help.

My dad couldn't give me a lift to the first lesson, so

We were having a math test that day so it was great that I could stay at home. I didn’t really 5., though. I felt awful and stayed in bed. Mum brought me cups of hot tea for my sore throat(and you know how much I hate tea! ). She 6.went to the chemist's and got me some vitamin pills. I have to keep taking these for a while 7.I can get stronger.

That afternoon Robbie came to visit me. He said he'd got something to 8.and pretended it was the math test that I'd missed "Mr Bank says you can do it at home instead,” he said, but I knew he was joking. I didn’t think it was very 9., but he did!

The next day, I was still a bit pale and didn’t have much energy, but I was feeling better. The day after that, I was able to go back to school.

Can you believe my luck? I went to the yoga class to feel 10.and instead I caught a cold!

Anyway, I hope you're OK. Write and let me know what you’ve been up to!

Bye for now!

One day Vimala and her new friend. Mary, were playing at school. Mary was a very quiet and shy girl but Vimala liked her. While jumping, Mary’s glasses fell off and broke. Just then the bell rang and they had to hurry to their science class.

“Oh dear, I'm going to be as blind as a bat. But we'd better hurry. It's Miss Lee's class, "said Maray.

At the start of the lesson, Miss Lee explained how to do the experiment to produce large eye crystals. Then she started to question the class. Nobody dared to give a wrong answer because Miss Lee was a very strict teacher Miss Lee held up a clamp(夾具) and said, "What do we use it for? What do we call it? All the girls looked down, while she looked at their heads for one to pick on. "Mary?" she finally asked.

Mary was sitting at the back of the class. She stood up and peered at Miss Lee, but she could not see clearly what the teacher was holding. She was nervous a bit and did not answer.

Miss Lee repeated her question. This time she spoke more slowly and there was anger in her voice.

"What is this used for ?" she asked

Vimala saw storm clouds climbing up to Miss Lee's face. She knew that the storm was about to burst on Mary, so she put up her hand. Miss Lee paid no attention to her and stared through narrowed eyes at Mary, waiting for an answer.

Mary did not know what to say. She looked to her left and right for help. Too seared to say out that she couldn’t see clearly, Mary hoped that if she kept quiet Miss Lee would ask somebody else.

Vimala guessed what was wrong, so she decided to take a risk. She jumped to her feet and said, "Excuse me. Miss Lee. Mary broke her glasses just before the lesson started. I don't think she can see the clamp clearly. "Then she sat down, praying (祈禱)that the ceiling would not fall on her.

“Oh!” Miss Lee said, a little surprised. She had thought that Mary was refusing to answer.

Now that she understood, her anger faded away. “Thank you, Vimala.” she said Then she turned

to Mary and said, “Come and look at this.”

Mary left her chair and went to the front of the class.

“It’s a clamp.” she said. "We can put it on a metal stand(支架) and use it to hold things in place.”

"Well, you got it right at last. "Miss Lee said with a brief smile. But you'd better not do any experiments until your glasses have been repaired. You can watch Vimala while she does the experiment.

The storm clouds disappeared. The smile disappeared from Miss Lee's face and she continued with the lesson. Vimala winked at Mary who peered at her and smiled weakly.

A. They were lost. B. They were broken C. They were left at home

2.Miss Lee was __________ teacher.
