The Peppered Moth, a kind of insect, is found in England. It is light brown in color and likes to settle on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.

But with the development of industry, smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place: in industrial areas, the Peppered Moth began to change color. It became darker as well. Although the change took several years, some scientists soon noticed that newly-born moths were a little darker than usual.

A scientist called Kettle Well decided to make a careful study of this. He marked some of the light moths and some of the darker ones, and set them free in the woods near Birmingham, an industrial city. Later he retarget as many the marked moths as possible ( The result was given in the chart ).

Kettle Well’s research was done in the early 1950s. Soon afterwards Britain introduced new laws to reduce smoke and factory pollution.

第二部分：阅读理解（共25小题。第一节每小题2分，第二节每小题1分；满分45分）
第一节 阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卡上将该项涂黑。
A gadget which makes water out of air could become the greatest household invention since the microwave.
Using the same technology as a dehumidifier（除湿器），the Water Mill is able to create a ready supply of drinking water because it can always get it from an unlimited source—the air．
The company behind the machine says not only does it offer an alternative to bottled water in
developed countries, but it is a solution for the millions who face a daily water shortage．
The machine works by drawing in wet air through a filter（过滤器）and over a cooling instrument which changes it into water droplets．It can produce up to 1 2 liters a day．The Water Mill will also produce more water when storms pass over, as the amount of water which is contained in the air increases．In keeping with its eco-development, the machine uses the same amount of electricity as three lights.
Inventor Jonathan Ritchey said: “The demand for water is off the chart．So people are looking for freedom from water distribution systems that are shaky and unreliable.”
The machine, which is about 3 feet wide, is likely to cost ￡800 when it goes on sale here in the spring．Its maker, Canadian Firm Element Four, roughly calculates that a liter of water cost around 20p to produce.
Environmentalists state that half the world’s population will face water shortage because of climate change by 2080．One in five is said to lack access to safe drinking.
The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent, but in Britain that won’t be much of a problem.
41．What does the underlined word “it” refer do?
A．Drinking water.              B．Invention.        C．Microwave.             D．Water Mill.
42．What do we learn about the machine?
A．It works in the same way as microwaves．
B．It is very expensive for families to afford.
C．It absorbs steam and turns it into water．     
D．It helps to make the water clean to drink.
43．What does the passage lead us to believe?
A．The cost of water will go up.  B．Bottled water will disappear sooner.
C．The machine is energy saving. D．The machine will be popular worldwide.
44．What’s the best title for the passage?
A．A New Way to Solve Water Problem.    B．A Machine to Make Water out of Air.
C．A Dehumidifier to Produce Water.     D．An Absolutely New Invention

People say teenagers are no good. They make too much noise in shopping malls; they drive recklessly（不顾一切地） up and down America’s main streets; they carry chips on their shoulders as big as the Sears Tower. And at least some of the time those things are true. But we shouldn’t forget that there are hard moments in the life of a teenager too.

I watched such a moment not long ago at a woman’s funeral. I didn’t expect the event to affect me. Through much of the ceremony, in fact, I remained unmoved.

The teenage grandson stepped forward. With his very first deep breath, every heart in that church was achingly reminded of something we had all forgotten. Softly he began: “I want to share a few values that Nana taught me. She never failed to see light in any situation. When our family dog would truely attract her, what would Nana say? ‘oh, what beautiful barking that dog has!’ That was Nana. ”

“She was a strong woman who often lived in the shadow of my grandpa, who was a successful businessman in this city. But she was the one behind the scenes who provided the strength and support for my grandpa’s career,” he said, with a voice now trembling, “That was Nana’s way.”

Through a low sob, he continued, “Whenever she did anything worth recognition, you ’d have to hear about it from a different source, because she was never one to show off.”

Finally, in a voice breaking free of sorrow, he looked up and said, “Nana taught me courage. She put up an incredible fight to the end, when she died peacefully, which is how she lived her life. That was Nana’s way, and I hope I can carry on in the same manner.”

There are no hearts as sensitive as those of teenagers, because everything is happening to them for the first time. The trouble with teenagers is that they haven’t learned to be controlled.

When that boy rose to speak about the woman who surely had been his truest and dearest friend, his honest voice dragged each of us out into the open where we could no longer hide in the calm ceremony . He exposed us to the truth about this very real woman who believed in a boy who probably tried the patience of many adults. He reminded us that his grandmother was more than another dot on the chart of life and death.

All over again we felt those powerful losses crossing our own hearts, and we knew that when you say good-bye to something happy, something young in yourself. And that something never really returns, and the pain never really goes away.

A. support his idea that young people are no good.

It was unusually quiet in the emergency room on December 25. I was triage nurse (分诊护士) that day. I didn’t _36_many patients, so I was not happy about having to _37_ on Christmas. Just then, five bodies _38_at my desk: a pale woman and four small children.
“Are you all sick?” I asked _39_.“Yes,” the woman said weakly. But when they got to describe their problems, things got a little _40_. Two of the children had headaches, _41_ they weren’t holding their heads like headache sufferers _42_ do. Two children had earaches, but only one could tell me which ear was affected. The mother complained of a cough but seemed to work to _43_ it.
_44_ was wrong, but I didn’t say anything except that it might be a little while before a doctor saw her. She _45_ , “Take your time; it’s _46_ in here.”
Then I checked the chart after the admitting clerk had finished registering the family. No _47_–- they were homeless. The waiting room was warm.
I looked out at the family huddled by the Christmas tree. The smallest one was pointing at the television and exclaiming something to her mother. The oldest one was looking at an ornament on the tree.
I went back to the nurses’ station and mentioned we had a _48_ family in the waiting room. The nurses, irritated about having to work on Christmas, suddenly felt _49_ for a family just trying to get warm on Christmas. The team went into _50_, much as we do when there’s a medical emergency. Only this time it was a Christmas emergency.
We were each entitled to a free meal in the hospital cafeteria on Christmas Day, so we _51_ that meal and prepared a banquet for our Christmas guests. We needed presents. We put together oranges and apples in a basket. From various departments, we _52_candies, crayons and other suitable items. As seriously as we met the physical _53_ of the patients that came to us that day, our team worked to meet the needs, and go beyond the _54_ , of a family who just wanted to be warm on Christmas Day.
Later, as the family walked to the door to _55_, the four-year-old came running back, gave me a hug and whispered, “Thanks for being our angels today.”
