Having drank too much, Alfred was driving along the country road at top speed while his car ran into an old man who was walking across the road. After looking around and thinking there was not a single person see the accident, he drives off without taking the old man to the hospital. The old man was frightening but kept the car number on his mind. About one month late, they went to court. Alfred’s lawyer said:” Alfred is experienced driver of more than 20 years.” “ If experience can prove that, here, you see, the old man had walked safe for over 60 years,” the old man’s lawyer replied.

A．Means of ewaste recycling B．How ewaste comes into being C．The benefit of ewaste recycling D．The technologies of ewaste recycling E．The importance of the electronic waste recycle F．Modern technology brings convenience and ewaste |
1.
Modern technology does bring us many conveniences（便利），from WiFi（无线网络）enabled cell phones and ever smaller laptop computers that make entire lives easy to energy efficient washers that use half the power and time to complete their tasks. However，these new toys and equipment finally become electronic waste （ 电子垃圾）（e waste）once they are out of use.
2.
E waste includes everything from empty printer ink containers to broken refrigerators. As people buy new items to replace aging electronics or make upgrades（升级），more electronic waste comes into being. In some cases，such as 2009's switch from analog（模拟）to digital television broadcasting in the United States，changes in technology are so great that old equipment may not even work at all with new systems.
3.
There are many reasons why it is important to recycle electronic waste. Much of the material used to construct electronics，including metal and plastic parts，can be recycled into new items at a discount of the cost and energy use needed to create things from new raw materials（原材料）. Additionally，many electronics contain poisonous substances （有毒物质）that are harmful to the environment and could be deadly if they go into an area's groundwater. When properly recycled，they can be reused and will not do harm to the environment. Because of these environmental concerns，many areas require by law that electronic waste be properly recycled.
4.
The availability（可用性）of ewaste recycling programs varies from place to place. In some areas，annual collections are held once or twice a year as a means of dealing with ewaste as well as used engine oil or other waste that is harmful to the environment. There are also some good alternatives （替代品） to recycling your ewaste. Any items that are in working condition can be given to friends or donated to charities（慈善机构）like Goodwill or the Salvation Army，who rely heavily on donations （ 捐赠） . Freecycling ，or passing on your unwanted items to those in need of them，is also a means of finding new homes for used items.
5.
Ewaste recycling helps protect the environment by reducing the amount of poisonous materials placed in landfills（垃圾场）and saving recyclable parts to save energy and other resources. Recycling is a way of life. Stick to that choice every single day and recycling will become second nature to us.
I suddenly heard an elephant crying as though frightened. Looking down，I immediately recognized that something was wrong，and ran down to the edge of the near bank. There I saw Ma Sha with her three¬ month¬ old calf struggling in the fast rising water，and it was a life and death struggle. Her calf was floating and screaming with fear. Ma Sha was as near to the far bank as she could get，holding her whole body against the rushing water，and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean （完全地）over the mother's body and was gone. Ma Sha turned quickly to reach it and pressed the calf with her head and trunk (象鼻) against the rocky bank. Then with a huge effort，she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment，she fell back into the river. If she were carried down，it would be certain death. I knew，as well as she did，that there was one spot (地点) where she could get up the bank，but it was on the other side from where she had put her calf.
While I was wondering what I could do next，I heard the sound of a mother's love. Ma Sha had crossed the river and got up the bank and was making her way back as fast as she could，roaring (吼叫) all the time，but to her calf it was music.

It’s never a real problem for us when the weather gets cold. We can put on more clothes, stay next to a fireplace, turn on the air conditioner or simply travel to a warmer city to spend the winter – people have many different ways of dealing with the cold.
But things are not as easy for plants. Unlike humans, plants can’t move to escape the cold or generate heat ( 发热) to keep themselves warm. So how do they manage to survive the freezing winter?
It turns out that plants have their own strategies （策略） too, said a study published on Dec 22 in the journal Nature.
According to researcher Amy Zanne of George Washington University, US, the cold is a big challenge for plants. Their living tissues （活组织） can be damaged when they freeze. “It’s like a plant’s equivalent to frostbite ( 相当于冻疮),” Zanne told Science Daily. Also, the process of freezing and thawing (解冻) can cause air bubbles （气泡） to form in the plant’s water transport system. “If enough of these air bubbles come together as water thaws they can block the flow of water from the roots to the leaves and kill the plant,” she explained.
To live through cold weather, plants have developed three traits （特性） , according to the study. Some plants, such as oak trees（橡树）, avoid freezing damage by dropping their leaves before the winter chill sets in – effectively shutting off the flow of water between roots and leaves – and growing new leaves and water transport cells when the warm spring returns.
Other plants, pine trees（松树） for example, protect themselves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.
The third strategy is also the most extreme – some plants die on the ground in winter and start growing as new plants from seeds when conditions get warmer.
However, the study also found that these smart strategies were developed very slowly – over millions
of years of evolution （ 进化）. This leads scientists to worry that plants may not be able to deal with human-caused climate change, which has only started occurring over the past few decades.
Scientists are hoping that this study can help people find possible ways to save plants from the threat
of climate change.
1.What is the article mainly about?
A. Why plants are not afraid of the winter chill.
B. The ways that plants survive cold weather.
C. Changes in plants’ water transport system in winter.
D. How plants evolve to keep up with climate change.
2. According to the article, if a plant freezes in the winter, ______.
A. it produces more living tissues to stay alive
B. its leaves quickly fall out and its roots begin to die
C. lots of air bubbles form in its water transport system
D. its water transport system could be blocked in the spring
3.What are scientists worried about when it comes to plants according to the article?
A. Plants may not be able to adapt to the increasingly cold climate.
B. Human activities might have a great impact on the pace of plants’ evolution.
C. Plants may not be able to evolve fast enough to adapt to human-caused climate change.
D. The strategies plants develop are not good enough to protect them against cold.
