Just a year ago, the colors were bright under the waves. Now it’s gray — the Maldivian reef is dead. The coral is killed by the pressure of rising temperatures.
Coral reefs are areas underwater where small creatures live. The coral is hard material formed on the bottom of the sea by the skeletons of those creatures. But the world has lost about half its coral reefs in the last 30 years. Scientists are working to prevent their destruction. Due to global warming, over 90 percent of corals are expected to die by 2050. “To lose coral reefs is to fundamentally undermine the health of a very large proportion of the human race,” said Ruth Gates, director of the Hawaii Institute of Marine Biology.
Why are coral reefs important? Coral reefs support a fourth of all marine species, as well as half a billion people worldwide. They serve as barriers to protect coastlines from the storms. They provide billions of dollars from tourism, fishing and other trade. They are also used in medical research for cures for diseases. “Everyone should be concerned,” said biologist Ove Guldberg at Australia’s University of Queensland. “This is not just some distant dive destination. This is the basic structure of the ecosystem we depend on.”
The ocean is getting warmer. A rising temperature of just one to two degree Celsius can force coral to expel the algae (驱逐海藻) that live there. This leaves their white skeletons uncovered. It is a process called “bleaching”. Sixteen percent of the world’s corals died of bleaching in 1998. The problem has become much worse in recent years.
“We’ve lost 50 percent of the reefs, but that means we still have 50 percent left,” said Ruth Gates, who is working in Hawaii to breed corals that can better withstand increasing temperatures. She is also trying to “train” corals to survive rising temperatures. Gates says it is time to start “thinking outside the box”— find creative ways to help them.
1.What does the underlined word “undermine” in paragraph 2 mean?
A.Regain B.Weaken
C.Promote D.Develop
2.What can we learn from Ove Guldberg’ words?
A.People won’t find a dive destination in the future.
B.The effort to save corals will turn out to be fruitless.
C.The bright sea has lost its charm because of those dead corals.
D.The destruction of coral reefs will affect the earth ecosystem.
3.What’s the fourth paragraph mainly about?
A.The harm of algae. B.The importance of coral reefs.
C.The process of “bleaching”. D.The change of ocean temperature.
4.What is Ruth Gates’ attitude towards the protection of corals?
A.Worried B.Positive
C.Casual D.Curious

A decade ago, colored lights danced around the living room on New Year's Eve and happy music was played. Upstairs, the children were asleep. But I wasn't feeling happy. In mid-December, my husband and I had been informed that he had cancer and that he was going to die. He had less than a year left, the doctors said.
In the years since that painful season, I have come to look back upon New Year's Eve as an ending and a beginning. New Year's Eve brings a halt to the endless commitments that fill our daily lives and a chance to reflect.
New Year's Eve is full of possibility, and anticipation. What will be the surprising experiences and delightful successes in the coming year? But also, what disappointments are waiting for us in the next twelve months?
In many ways, New Year's Eve and the days that surround it are a line between past and future. That line is made up of a series of moments of transition that take us out of the old and into the new. Transition can be challenging for many of us. It's about letting go of the familiar and diving headlong (迅猛地)into the unfamiliar.
Just as, back then, I had to face letting go of the life I had led with my beloved husband and stepping into a new world as a widowed(丧偶的)mom. I find that each year I have to step out of the version of me that suited the year that is ending and ease into the version of me who will rise to the goals I am holding for myself for the year ahead.
Last year at this time, I sat in a chair in southern France and drank in the stillness and beauty of the countryside around me. The three children and I had brought into this world talked and laughed around the table beside me as we enjoyed a lunch of bread and cheese.
I was filled with a sense of joy and I had a glowing (热情洋溢的)heart that was full of hope. It was another ending and another beginning. May we all transition into the best of what lies ahead. May we all find happiness in this holiday season.
1.What made the author unhappy on New Year's Eve a decade before?
A.The pressure she faced in her work.
B.The health problem her husband faced.
C.The information received from her family.
D.The relationship between her and husband.
2.What does the underlined word "halt" in Paragraph 2 mean?
A.Stop. B.Beginning. C.Meaning. D.Tradition.
3.What does the author think people should do at a new year?
A.Set challenging goals for the next year.
B.Break with daily routines and form a new habit.
C.Spend more time with family members.
D.Think about the past and get ready for the future.
4.What is the author's attitude toward the future?
A.Calm. B.Indifferent. C.Doubtful. D.Expectant.
5.What is the main purpose of the article?
A.To memorialize her husband.
B.To show how she got through a hard time.
C.To share her view of New Year's Eve.
D.To remind us that uncertainty is part of life.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Two brightly colored butterflies have just flown by. They seems to be exactly alike, but actually one is a little larger than the other. ________1.The smaller one has a wingspread of less than three inches and also a black line on its back wings.
At first sight, it is hard to tell them apart. Would you guess from this that they are different-sized butterflies of the same species? ________2.If you said yes to either question, you would be wrong, for these look-alikes belong to quite different families.
The larger insect is the monarch butterfly (黑脉金斑蝶). As a baby insect, the monarch feeds on milkweed, which seems to give the monarch a disagreeable taste and smell. ________3.Birds that eat butterflies soon recognize the monarch and quickly learn to leave it alone.
4.Birds would find this insect tasty, but because it looks like the monarch, birds keep away from it. The viceroy’s similarity to the monarch gives it some protection from its enemies and helps it survive.
There are other pairs of look-alike butterflies, bees and moths. In each case, one either has a disagreeable taste or smell, or can give a painful sting (叮咬). The larger is called the model. ________5.(词数206)
A. The smaller insect is the viceroy (副王峡蝶), which feeds on the leaves of trees.
B. The larger insect has a wingspread (翼长) of up to four inches.
