Michael Shirazi is a 67-year-old American who has been feeding more than 150 homeless cats in Shanghai for the past eight years. Every night, he leaves his home at 11:00 pm and takes 20 kilos of cat food to the street to feed the homeless cats. So he is called by people "the king of homeless cats".
Eight years ago, Michael came to Shanghai for his family's business. At that time, he was a successful businessman. Until one day after living in Shanghai for a year, a homeless cat he named "short tail" came into his life. He still remembers the night when he saw "short tail" and the way it searched for food in the garbage can for her and her newborn babies. He had pity on "short tail" and brought it food and water. Since then, he has been feeding more and more homeless cats. He even shut down his company and closed his family business because of it.
These homeless cats have brought many happy moments to Michael. Every time they see him, they jump with excitement and kiss him. But unfortunately, his wife left him because he no longer managed his family business and spent nearly 10,000 yuan a month on cat food. Though all the things happened to Michael, he still leaves his home on time every night.
Michael said, "My experience makes me feel that people are made of love. We must return our love to the world so that we can find our inner(内心的) peace." This is the happiness he gets every night when he's on his way to feed cats: feeling loved and needed.

This is the SCIENCE IN THE NEWS; I'm Barbara Klein.
Animal experts say one of the world's most beautiful and rarest kinds of big cats is close to disappearing from the wild. A study earlier this year found that about thirty Amur leopards (豹) still live free. The cats are also called Far Eastern Leopards.
Recently, their number has been reduced one by one. Some person shot a female Amur leopard, and then beat her to death. The animal's body was discovered last month in the Barsovy National Wildlife Refuge in eastern Russia.
An official of the World Wildlife Fund, Darron, said this was the third such killing in the area in the past five years. Mr. Collins said the death of even one adult female is a huge loss for the endangered cat. He noted that the killing reduced the possibility of cubs' (幼兽)survival.
It is not clear how many Amur leopards still live free. One population count was performed in February and March. Wildlife expert Dmitry Pikuuov led this study. It found evidence of seven to nine males. The study identified three to seven females without cubs. Four leopards were identified as females with cubs. In all, five or six cubs were recorded. Six to eight animals could not be identified.
Most of the land where the Amur leopard once lived was in China. New roads and climate change there threatened the animals. So did hunters who kill big cats for their body parts.
Mr. Pikuuov says adult Amur leopards need about five hundred square kilometers with good forests to survive. He said they also need a large and continuing supply of animals like deer for food. He believes the answer to saving the Amur leopard's problem is for governments to provide protected space for wildlife.
1.This passage is probably from ______.
A.a magazine B.a newspaper report C.a TV report D.a film
2.Why is the killing of an adult female Amur leopard a huge loss
A.It could lead to the death of an adult male.
B.It means it cannot give birth to the young any more.
C.It is worth more money than a male.
D.There is only one adult female in the world.
3.What cause the number of the Amur leopards in China to decrease
①new roads ②climate change ③human hunting ④rare diseases
A.①②③ B.①②④ C.①③④ D.②③④
4.According to the experts, the Amur leopards ________.
A.are living on plants B.are living in the zoo
C.are well protected by people D.are endangered
D
The situation of the world's plants is not good. One fifth of the kinds of plants are in danger of disappearing, according to a report.
"Plants are very vital to human beings," said Kathy Wallis, who led the new report. "Plants provide us with everything—food, fuel, and medicine, and they are very important for our climate controlling. Without plants we would not be here."
The good news is that deforestation rates(森林砍伐率) around the world have dropped largely since the 1950s. However, this report on the health of plants around the world shows that there is much more to be done.
The report predicts that there are now 390,900 kinds of plants. And about 21 percent of those plants are in danger of disappearing. "The good side is that we're still discovering lots of new plants, about 2,000 each year," said Dr. Willis. "The bad side is that we've seen a huge change in land cover, mainly caused by cultural activity, with a little bit of climate change in there as well."
Human activity has a great effect on the danger of plants disappearing. As humans cut down forests to make room for agriculture(农业), towns and cities, biodiversity(生物多样性) is lost. This could not only affect our own food supply directly, but also affect the food web.
1.What does the underlined word "vital" in Paragraph 2 probably mean
A.Useless. B.Friendly. C.Equal. D.Important.
2.Which of the following does Dr. Willis agree with
A.New plants are more than ever before. B.About half the plants will disappear soon.
C.Many new plants are found every year. D.Plants mustn't be used to produce medicine.
3.What can we learn from the third paragraph
A.We have made little progress. B.There is a long way for us to go.
C.We have achieved our goal. D.There will be nothing we can do.
4.What is the best title for the text
A.Biodiversity Being Lost B.Human Social Activity
C.Environment Protection D.Nature Climate Change

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
Located halfway up the Italy's Apennine Mountain, about 100 miles northeast of Rome, the Hotel Rigopiano has never been easy to reach. But its isolation (only adds to its appeal, attracting a great number of tourists.
Snow began to fall across the Apennines in January and lasted for days. From his home in the Rome suburbs, Matrone watched the weather with concern. He and his wife,Cicioni, had planned an overnight getaway to the hotel. But now he wondered whether they should go. After phoning the hotel, they decided to make the trip. By the time they neared the hotel six hours later, they were battling a snowstorm. When they finally arrived, they were both cold and exhausted. They checked into their room and went to bed early.
As they awoke the next day, they discovered that their difficulty had worsened overnight. The cars in the parking lot were invisible. The phone and power lines were down. They were having breakfast when the hotel began to shake. An earthquake with a magnitude(震级) of 5.7 had struck the mountain. "Get out of here!" Matrone shouted to his wife. They headed quickly to the parking lot, where others were digging their cars. Fifteen minutes after the first earthquake, another quake hit, this one measuring 5.6.
With a dozen vehicles freed by noon, the guests set off down the driveway. But when they reached the main road, the path was blocked by a six-foot-high wall of snow. Matrone climbed out of his car and investigated it. There was no road in sight, "We're trapped!" he told his wife. So they had no choice but to make their way back to the hotel.
As it was getting dark, they managed to be back. That was when the snow on the mountain began to slide. They heard the avalanche (雪崩) before they saw it. The avalanche gathered speed and size, grabbing rocks and trees and anything else in its way down the mountain, tearing the hotel from its foundation. When the avalanche came to a stop, those who were caught inside the hotel were left buried in the icy rocks and ruins.
注意：
1. 续写词数应为150左右；
2. 请按如下格式在答题卡的相应位置作答。
When Matrone came to himself, he was stuck in the darkness. _____________________

第三部分 写作
第一节
答案：
Dear WWF,
I'm Li Hua, one of the middle school students. I am writing to inform you of the situation where the birds are living. Some people are catching the lovely birds on the top of the mountain. What's worse, a few people even put birds on tables for dinner.
It is known that birds are human beings' friends. We should live harmoniously with them. For one thing, they can catch pests. For another, without birds our forests would not be lively.
In order to protect birds from being caught or killed, we should widely spread the laws of animal protection. Besides, education and raising people's awareness are also effective measures.
Yours,
Li Hua
第二节
答案：
When Matrone came to himself, he was stuck in the darkness. Lying on his stomach, he realized with horror that he was under something heavy and couldn't move at all. "Cicioni! Cicioni!" he called, but there was no response. He could hear nothing of what was happening at the surface. The whole world was dead still. What he had to face was a terrible reality—they were buried alive. Despair washed over him. He asked himself again and again, "Who is going to save us "
It was not until the next morning that the rescuers finally arrived. Without any hesitation they got down to detecting the remains of the hotel and they were delighted to discover that there were signs of life. With great efforts they removed the thick snow and began cutting the roof. Then they carefully lowered themselves through the hole they'd made. Suddenly, they heard someone crying for help in a weak voice. It was Matrone. Later all the survivors were rescued including Matrone's wife. The couple felt really lucky to be still alive.
