We all know that smoking is bad for people’s health. But not many people know about the danger of secondhand smoke.
Secondhand smoke is the smoke that comes from the smoker’s breath(呼吸). If people breathe in secondhand smoke from time to time, they could get sick from it.
But how serious is the problem of the secondhand smoke? The World Health Organization(WHO) did a study of 194 countries. They found that secondhand smoke causes about 600,000 deaths every year. That is about 1% of the world’s deaths.
Secondhand smoke is especially bad for children because their bodies are still growing. According to the study, around 165,000 children under the age of 5 die each year because of secondhand smoke. Most of these deaths happen in Africa and southern Asia.
You can do something to keep yourself and other people away from secondhand smoke. You can ask the smokers, such as your parents, to smoke outside. And, if someone smokes close to you, you’d better hold your breath or just walk away.

The ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave?” asked Jamie Taylor of the Wave Energy Group in Scotland. “There is certainly a lot of energy in waves.”
Scientists are working on using that energy to make electricity. The United States and a few other countries have started doing research on wave energy, and it is already being used in Scotland.
Most waves are created when winds blow across the ocean. “The winds start out by making little ripples (波纹) in the water, but if they keep on blowing, those ripples get bigger and bigger and turn into waves,” Taylor said. “Waves are one of nature’s ways of picking up energy and then sending it off on a journey.”
When waves come towards the coast, people can set up dams(大坝) to block the water and send it through a large wheel called a turbine(涡轮). The turbine can then power an electrical generator(发电机).
We will never run out of wave power. Besides, wave energy does not create the same pollution as oil and coal do.
Oceans cover three quarters of the earth’s surface. That would make wave power seem perfect for creating energy around the world. But there are some disadvantages that need us to pay more attention to.
Jamie Taylor said that wave power still cost too much money. He said that its influence on animals in the sea is still unknown. Besides, wave power would get in the way of fishing and boat traffic.
With more research, “Many of these problems might be solved,” Taylor said. “Finding more energy sources(资源) is very important, for traditional sources of energy like oil and gas may run out some day.”
In the future, when you turn on a light button, an ocean wave could be providing the electricity!

I love my iPhone---it’s my little connection to the larger world that can go anywhere with me. I also love my computer, as it stores all of my writing and thoughts. Though I love these devices(装置) of technology, I know that there are times when I need to move away from them and truly communicate with others.
I teach history in a high school. My goals for the class include a full discussion of historical themes(主题) and ideas. Because I want students to thoroughly study the material and share their ideas with each other in the classroom. I have a rule---no computers, iPads, phones, etc. When students were told my rule before class, some of them were not happy at all.
Most students think that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There’s a bit of truth to that. Some students believe that I am anti-technology. There’s no truth in that at all. I love technology and try to keep up with it so I can relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversations. Interruptions(打断) by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for ideas. I want them to push each other to think differently and to make connections between the course material and the class discussion.
I’ve been teaching my history class in this way for many years and students realize that with deep conversation, they learn at a level that helps them keep the course material beyond the classroom.
I’m not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change. A few hours of technology-free dialogue is just too sweet to give up.What’s the second paragraph mainly about?
| A．The reasons why students should use computers or iPads in class. |
| B．The advantages of using cell phones and computers in the classroom. |
| C．What the writer is trying to do and what rule has been made in class. |
| D．A new learning style that the teacher enjoys using in history class. |
According to the writer, the use of technology in the classroom may _____.
| A．improve teaching and offer more help |
| B．allow students to get on well with each other |
| C．help students concentrate on what they learn |
| D．keep students from making deep conversations |
What can we infer from the passage?
| A．The teacher will carry on the success in the future. |
| B．The teacher will have to cancel the rule in class. |
| C．Some students will be punished according to the rule. |
| D．More and more students will be absent in history class. |
My five brothers, my sister and I lived in Toronto with our parents. My father worked in a factory, and my mother stayed at home. Each year my father would dress up as Santa Claus and go through the streets sharing joy and candies with the children there. He loved it as much as they did!
But around Christmas in 1970, my father was out of work. In fact, there was no money for Christmas and my parents weren’t sure how they’d provide for us.
That Christmas Eve, however, as usual, my father left the house dressed as Santa Claus. He knew that even though our Christmas would be hard, he could not make the other kids in the neighborhood disappointed.
As my father left the house and went downstairs, another Santa Claus was walking up, with a great bag of gifts for us! He said nothing, only smiled a sweet smile at my father, and wished him a merry Christmas. The jolly man handed the bag and walked away down the block.
We never knew who showed us great kindness on the snowy Christmas night. We do know, however, that without him we would have had nothing under the tree. His kindness gave my parents hope and showed us in a very real way the true meaning of Christmas.
Our family has never forgotten this kind stranger and his generosity(慷慨). Each year we tell the story of the mysterious(神秘的) Santa Claus and try to repay his gifts by giving help to others in need.According to the passage, the writer’s father is ______on Christmas.
