1Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere (大气).

The climate is changing. Many agreed that climate change may be one of the greatest threats (威胁) facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities (极端性) in weather patterns.

Is the Earth getting warmer? Yes! The Earth has warmed by about 1°F over the past 100 years. But why? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world’s leading climate scientists think that things people do are helping to make the Earth warmer.

Global Warming may be a big problem, but can you make a difference? Yes! There are several little things you can do to make a difference. Try carpooling. This will help reduce the amount of fossil fuels going into the atmosphere. Whenever you use electricity, you help put greenhouse gases into the air. Turn off lights, the television, and the computer when you are through with them. Also, planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. Finally, don’t forget about recycling.

When I was a foreign teacher in China，every day I taught English to my students and they taught me about China．One day the topic mined to saying “I love you”．I was shocked to learn that not one of my students had said this to their mothers，nor had their mothers said it to them．“Does your mom love you?” “Of course，”they answered．

“How do you know?” was my logical question．They responded that their moms cooked and Always told them what they were doing wrong to show their earning．I was strummed. So mom's cooking and criticizing read our as “I love you”．”Then how do you say ‘I love you to her?” They agreed that getting good grades, followed by good jobs would be how they showed their love.

I come from a culture where most people are expressive enough，so I repeated these queries in clauses over time．Gradually，I began to get different responses．Some of them had exchanged those sentiments with their moms．

One of my favorite stories of change came from a girl．When she came home from university，her mother met her at the door and hugged（拥抱）her．This had never happened before，but her mom said，“Now that you have gone I have more time to myself．I noticed that in some places mothers and children hug each other and I decided it was a good idea and that I would begin hugging you．”

In my family we all say “I love you” a lot．While it is true that we often say the words without having great depth of feelings at that moment，it is almost like a blessing we give each other. Those three little words carry a world of meaning，even when said as a greeting, but most especially if they are the lax words we say to or hear from those we love．

1.The foreign teacher _________．

2.Chinese people prefer to show love by __________．

3.In paragraph 4, what's the real meaning of the mom's hugging?

4.What's the main idea of the passage?

I was now five, and still I showed no much interest in things except with my toes（脚趾）. I could not look after myself,   35  my father took care of me. I used to lie on my back all the time in the kitchen. I was   36 , imprisoned（监禁） in a world of my own, unable to communicate with others.
Then, suddenly, it happened on the afternoon of a cold December day. All the family were gathered round the big kitchen fire. Mona and Paddy were drawing funny animals, using a bright piece of yellow chalk. It was the chalk that   37  me so much. I had never seen anything like it before.
Suddenly, I wanted to do what my sister was doing. Then without thinking or knowing exactly what I was doing, I   38  out and took the chalk out of my sister’s hand, with my left foot. It is a puzzle（迷惑）to many people as well as to   39 . I held the chalk tightly between my toes and made a wild scribble（乱涂）with it on the board. Next moment I stopped, not knowing what to do with the chalk next, hardly knowing how it   40  there. Then I looked up and realized that everyone was looking at me   41 . My mother came in. Her eyes looked from my face down to my   42 , then she took another piece of chalk from Mona, and drew the single letter “A” on the floor in front of me. “Copy that, Christy.” She said. I tried to do the same action, but I   43 . “Try again, Chris.” she whispered in my ear. I tried another two more times. I drew one side of the letter, then the other. It looked ugly, but I   44  to make it finally. I had done it! True! I couldn’t speak with my mouth, but now I would speak through something more   45  than spoken words. That one letter was my   46  to a new world, my key to mental freedom.
