Is your TV connected to the Internet? What about your chair or your fridge? It is possible that they are not. But in the future, most things in your home may be connected, as the so-called "Internet of things" is developing.
The Internet of things may be coming sooner than you think. It is reported that during his speech earlier this year, Samsung CEO(首席执行官)BK Yoon spent a lot of time talking about the Internet of things. He said that five years from now，every Samsung product will be part of the Internet of things, whether it's a washing machine or a vacuum cleaner(吸尘器).
So, how do household(家用)objects that are part of Internet of things work? Well, think of a usual chair. When connected to the Internet, the chair warms up when it knows that the user has just walked into the room and is feeling cold.
An Internet-connected camera, like a smart-home camera, could help people feel safer in their homes. It can recognize(识别)people's faces, and even can see when someone passes by in the dark. Then it can send you a message on your smartphone to let you know who's there. If the person is someone you don't know, it can tell you that, too.
But according to MIT Technology Review, whether companies are connecting dog food bowls or security(安全)systems to the Internet, there may be problems. For example,many early connected-home devices(装置)don't have much built-in security, which means they could be hacked(被黑客攻击)，In addition, it could be difficult to get these devices to work together because they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2014.
So, picture this: you walk in through the front door of your home. The temperature changes to make you feel comfortable after a long day at school. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think.The Samsung CEO's speech is mentioned to prove that_____.
| A．the Internet of things will appear in our daily life sooner |
| B．Samsung has produced the Internet of things recently |
| C．Samsung products have been part of the Internet of things |
| D．he spent a lot of time talking about the Internet of things |

| A．the chair can know whether the user feels cold or not |
| B．a usual chair can warm up when it knows the user comes in |
| C．an Internet-connected camera can be used to take photos in the house |

Bicycles are very popular in China. In our country you can see bicycles almost everywhere. When you walk on the road, you will find a lot of people riding bicycles to school, shops and anywhere else.

American nutrition expert Professor Barry Popkin says that the number of overweight people in the world is now bigger than the number of people who don’t have enough to eat. A billion people worldwide now weigh too much and the number of obese people is now more than 300 million. “Obese” means at least 15 kilos heavier than you should be. However, there are also 800 million people in the world who don’t have enough to eat.
Professor Popkin says that the number of hungry people is falling slowly but the number of overweight people is rising fast. The main reasons for this are:
● People are doing less hard physical work
● More people worldwide now eat too much fatty food
● Too many people are driving cars instead of walking
● People spend too much time in front of a television
The United States has the highest rate of obesity in the developed world and Japan has the lowest. Professor Benjamin Senauer is absolutely certain of the reasons for this.
“Japanese people are fit. They use public transport and walk,” he said. “The average American drives to work and drives to supermarket. When he gets home, he sits on a couch in front of the TV and eats junk food.”
In Britain and many other European countries, there are three times as many obese people as there were 20 years ago. About two thirds of British adults are overweight or obese. “The effects of this are clear,” said London doctor Elena Power. “We have more illnesses related to weight and fewer fit people.
China used to be one of the slimmest nations in the world. However, Professor Wu Yangfeng from the Chinese Academy of Medical Sciences in Beijing recently estimated （估计）that 20 percent of the world’s overweight people live in China. The Chinese government is especially worried about the increase in obesity among schoolchildren.
“We have a serious problem,” said Professor Wu. “It requires an improvement from everyone, or it will get worse. How many people weigh too much in the world now?
| A．A billion. | B．20 billion. |
| C．300 million. | D．800 million. |
Professor Popkin probably agrees that_______.
| A．walking to work helps people keep fit. |
| B．watching TV makes people put on weight |
| C．eating food without fat helps people keep fit |
| D．working in offices makes people put on weight |
Which of the following is Not True according to the passage ?
| A．Being overweight can cause more illnesses. |
| B．About two thirds of British people are overweight. |
| C．More and more schoolchildren are overweight in China. |
| D．Most Japanese people are healthier than those in other countries. |
What does the writer try to tell us in the passage?

| D．The number of overweight people is growing. |
When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book; and so a poor man bought it for a few coppers（铜钱）.Between its pages there was something very interesting. It was a thin paper on which was written the secret of the “Touchstone”!
The touchstone was a small pebble（卵石）that could turn any common metal into gold. The writing explained that it was lying among thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles were cold.
So the man camped on the seashore and began testing pebbles.
He thought that if he picked up ordinary pebbles and put them down again, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone.
The days became weeks and the weeks into months. One day, however, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea .So when the one he wanted came along, he still threw it away.
So it is with opportunity. Unless we are careful, it’s easy to fail to know an opportunity when it is in hand and it’s just as easy to throw it away.The book was special to the man because ______.
| A．it was made of cotton |
| B．it was the only book that was saved from the great fire |
| C．it was a story about how to tell the touchstone from ordinary stones |
| D．it included the secret of the touchstone |
The man threw pebbles into the sea ______.
| A．to test how far he could throw |
| B．to practice throwing pebbles |
| C．to avoid picking up the same pebble once again |
| D．to express his disappointment at failing to find the touchstone |
The story is written mainly to tell us that___________.
| A．careful habits can lead to success. |
| B．habits can benefit you but also hold you back. |
| C．never judge a person or a thing by appearances. |
| D．opportunity only visits the ready and watchful mind |
I was born an albino(白化病人）in Pennsylvania in 1945．No one in my family had ever known what an albino was and what it meant to be an albino.
My family and friends treated me as everybody else．That was just about the best thing they could have done．It helped me believe in myself, so when troubles came along, I could deal with them．
Like most albinos, I had the terrible eyesight, but the fact that I could hardly see didn’t bother me that much .Kids would make fun of me, calling me“Whitey”． People looked at me when I held the books right at the tip of my nose so that I could see it well enough．Even when I was eight, movie-theater workers started asking me to pay full prices because I“looked older”．The worst thing for me was that because my eyesight was so bad, I couldn’t play sports very well．I didn’t give up trying, though．And I studied harder．Finally, I got better at school and loved it．When I got to university, I was double majoring(双修), going to summer school and busying myself with every activity I could find．I had learned to be proud of being an albino．I did my best to make“albino”a good word．And I decided to make my living with my eyes—and in sports．
I couldn’t see very well to play sports, but with a good education and a drive to do it, I could make a living in the area I loved．I’ve done it now for more than thirty years in video, and now in cyberspace(网络空间)．People make jokes about how I’m the only“blind editor”they know, but the jokes are of goodwill and some of them are signs of respect(尊重)．
