Howto Keep Fit

阅读下面的短文．并根据短文后的要求答题。

    Since 1850．the temperature of Earth’s surface has increased about 0.6°C．Scientists predict it may warm much more by the end of this century．Who’s turning up the heat? Well, it seems that we are! Some of this global warming may be natural．However，nearly all scientists now agree that most of it is due to peoples actions．Over the past 150 years, we've added huge amounts of certain gases, especially carbon dioxide（CO₂）to the air．These gases can keep heat near Earth's surface，so more carbon dioxide means more heat is kept near Earth's surface．Global warming may change the weather in ways that lead to more severe storms，floods and droughts．

We add carbon dioxide to the air when we burn things, especially fossil fuels．Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago．Coal，oil，and natural gas are all fossil fuels．People in the United States and other countries started bunting large amounts of fossil fuels more than a century ago．The amount d fossil fuels being burned each year has been increasing worldwide．The more we burn，_____________________．

What can we do to help? Nowadays to live a low-carbon life is quite popular in the world．Low-carbon means to reduce the amount of carbon dioxide．Saving energy and reusing are the key words. In fact, even the simplest everyday activities can make our lives low-carbon．

1．What problem can global warming cause?（根据短文内容回答问题）

2．What are fossil fuels?（同上）

3．请将第一段中的划线句子翻译成汉语。

4．请根据第二段内容，将最后一个句子补充完整。

 阅读下面的短文，用括号内所给词的适当形式填空，必要时可加助动词。请将答案填写在文后相应的横线上。

During the Second World War．John's family didn't have a washing machine．Therefore，1   （keep）clothes clean became a problem for them.

Before long，a family friend decided  2   （join）the army and his wife was going with  him．John's family told them that they could take care of their furniture while they were away. To the  3   （family）surprise，the friend suggested they should use his Bendix washing machine．“It would be better for it to  4  （use），rather than sitting  5 （quiet），”he said．

Young John helped with the washing，and he developed a deep love of the old，green Bendix．6（Late），the war ended and the family's friend returned．When he came to take the machine away．John became very sad．His mother saw this and said to   7  （he）．“Son， you must remember that machine didn't belong to us in the  8   （one）place. It was a gift for us to be able to use it for such a long time．So，instead of  9 （be）sad about the loss．Let’s be grateful that we  10 （be）able to use it at that time.”

We have all experienced loss：loss of people and things．However，if we see the thing we 11 （lose）as a gift that we were given for a time，maybe the sad  12 （memory）will change into  13（thank）ones．

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．
