Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida’s weather. Warm sunshine and gentle rains, along with Ed Rawlings’ expert care, will produce a good crop(收成)of oranges this year.
However, Ed has to guard against Florida’s changeable winter weather. In January and February, temperatures can destroy Ed’s entire orange crop. Having farmed in Florida for the past 35 years, Ed is prepared for the frost(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer(层) of ice around the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.
What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is taken in by the fruit and keeps its temperature at a safe level. Ed has effectively used this method to save many orange crops.
But Ed still faces difficulties. The trees must be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity(数量)of water must be used. Too much water can form a thicker layer of ice that will break the tree’s branches(树枝). Another difficulty is that wind blows away the heat, so Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.
Computer technology may help Ed with some of these worries. With equipment(设备), air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate(计算) when the temperature will drop below freezing. The computer can correctly decide the quantity of water to be used and how frequently(  ) the trees should be watered. Ed finds looking after his orange trees a lot easier with the help of a computer, and, his customers will have the benefits(利益) of computer—age oranges.

You may have heard of the famous saying, "East or West, home is the best. "
What does the word "home" mean to you? How do you say the word in French? In Chinese? In your language? Although people usually know what the word means, it sometimes has no exact translation. It’s not surprising, because the idea of home is "different from country to country, and from person to person. A home is more than a roof and four walls. It’s the cooking, eating, talking, playing and sleeping that go on inside. And at home you usually feel safe and relaxed.
Homes look different in different countries. They also have different things inside. For example, in cold northern Europe, there’s a fire in the living room or kitchen and all the chairs face it.

Everyone worries. But how do you deal with your worries? Whether your worries are big or small, you can take these three steps to do with your worries:

Fashion isn’t very environmentally-friendly because it makes people buy things they don’t need, just because they’re new. We want to take care of the environment, we don’t want to pol­lute the air and we don’t want to waste energy and resources. But we also want to be fashiona­ble. How can we buy fashionable clothes and protect the environment?
Old styles are fashionable again, so one way is to buy second-hand clothes — recycled clothes. Another way is to buy’ fair trade clothes. These clothes are either recycled or made in a ’ way that protects the environment. They also protect the people who make the clothes.
Surprisingly, white cotton is one of the least environmentally-friendly crops of all. To pro­tect the cotton, the growers use chemicals that pollute water, make farm workers ill and kill wildlife. New materials, such as hemp and bamboo, grow quickly and are more environmental­ly-friendly. These materials are very soft, and look fantastic. The best materials are coloured using natural dyes, made from plants.
Environmentally-friendly clothes are practical but until now they were often dull. Now fashion-designers are working with these materials and the clothes are beautiful as well. So now we can buy fashionable clothes that are also environmentally-friendly.
小题1:Why do people often buy things they don’t need? Because_.
A.new things can be more comfortable
B.everyone wants to be fashionable
C.people are richer than before now
D.people care about the environment
小题2:What’s the topic for paragraph 2?
A.Recycled fashion.B.The problem with fashion.
C.Fashion doesn’t have to pollute.D.New materials.
小题3:Which of the following is more environmentally-friendly?

小题4:Why are environmentally -friendly clothes more fashionable now? Because______.
A.people pay more attention to our environment
B.environmentally-friendly clothes are practical
C.all old styles become fashionable again
D.fashion-designers are working to make them beautiful

One night I was sitting in my room half-listening as my 15-year-old brother Tommy fought with my 12-year-old brother Kevin. I didn’t pay attention when Kevin rushed up the stairs with the hurt on his face.
About 20 minutes later, as I was walking upstairs I heard Kevin crying inside the bathroom. I knocked on the door and asked, “Hey Kevin, do you want to talk?”
No answer.
I tried again, “Why don’t you come out of there?”
Again, no answer.
So, joking around, I grabbed a stack of (一摞)cards and a pencil and wrote, “If you don’t want to talk, we can write notes to each other.”
An hour later I was still sitting on the floor outside the bathroom with two stacks of cards in front of me. One was blank and one was cards from Kevin on which he had translated all his yucky feelings into words for me. As I read one of Kevin’s notes, tears came to my eyes. It said, “Nobody in this family cares about me. I’m not the youngest, and I’m not the oldest. Tommy thinks I’m silly and Dad wishes he had the other Kevin as a kid because he’s better at basketball. And you’re never around to even notice me.”
Tears came to my eyes as I wrote back to him. “You know Kevin, I really do love you and I’m sorry I don’t always show it. I am here for you and you are loved in this family.”
There was no answer for a while, but then I heard a tearing sound coming from inside the bathroom. Kevin, who had run out of cards wrote on a torn paper cup. “Thanks.”
I wrote back “For what?” it returned to me with “Loving me” on it.
Since then, I try my best to never only half-notice my family members any more. Kevin and I have a closer relationship now. And sometimes when one of us notices that the other is upset, we’ll smile and say “Write it on a paper cup.”
小题1:The underlined word “yucky” most probably means ____.
A.upsetB.excitingC.terribleD.amazing
小题2:What could be the reason that Kevin’s Dad doesn’t like him?
A.Kevin is not as clever as his brother.
B.He is neither the youngest nor the oldest.
C.Kevin doesn’t like to make friends with others.
D.Kevin is not good at playing basketball.
小题3:What do we know about the writer?
A.She has two children in her family.
B.She didn’t pay enough attention to Kevin before.
C.She used to show her love to Kevin.
D.She has a closer relationship with Tommy after that.
小题4:What does the writer want to tell us?
A.Everyone should show how they love their family members.
B.It’s hard to get on well with family members.
C.It’s important to keep peace in the family.
D.We should try our best to stop our children from fighting.

In London, there has always been a main problem. In order to solve this problem, the government has decided to have a bike revolution(革命). It has decided to provide 6,000 bikes for the people to rent. The government encourages local people to ride bikes in order to solve the traffic problem.
More than 12,000 people have agreed to the idea. Some of them ask for more than one key. Although there are not enough bikes, an official(官员) from the government said that they would find some ways to deal with such a shortage.
Local people can get these bikes at special docking stations(停靠站).There are about 315 docking stations across the city. About 12,450 keys have already been handed out to the local people, but only 6,000 keys can be used now.
Let’s see the cost you need to pay. One key costs £3, and the cost of using the bike is £1 for an hour. The cost per hour increases as the hours increase, so it will cost £50 if you rent the bike for 24 hours.
