Elephants might be the most well-known and well-loved animals in African wildlife.But conservation（保护）of the African elephants faces special difficulties.While the elephant population is half of what it was 40 years ago,some areas of Africa have more elephants than populated areas can support.That，s why AWF scientists are studying elephant behaviour,protecting habits and finding ways for humans to live peacefully with elephants in Africa.
Years ago^overhunting and the ivory trade were the biggest threats to elephants
survival.Luckily^ivoiy bans（禁令）,hunting rules and protected areas protect elephants from these dangers today.
The 21st century brings a different challenge to elephant conservation一land use.Elephants walk across borders and outside parks and other protected areas.So they often destroy crops,causing conflicts （冲突）between local farmers and these big animals.
Successful conservation strategies（策田各）must allow elephants to walk freely in their natural habitats while people reduce conflicts between elephants and local people.
AWF researchers are searching for a way to give both elephants and people the space they need.The AWF is collecting information on elephant habitats and behaviour.The information they gather will help to develop the widest possible space for elephants・

We carf t live without these plants.If we continue like this,we will destroy ourselves・What will happen in the future?Perhaps it is more important to ask “What must we do now?” The people who will be living in the world of tomorrow are the young of today.A lot of them know that conservation is necessary.Many are helping to save our world.They plant trees,build bridges across rivers in forests,and soon.In a small town in the United States a large group of girls cleaned the banks of 11 kilometres of their river. Young people may hear about conversation through a record called "No one's going to change our worlcT.lt was made by the Beatles,Cliff Richard and other singers.The money from it will help to conserve wild animals.

"Wild animals seem to have escaped the Indian Ocean tsunami (海啸),adding weight to the notion they possess a "sixth sense" for disasters J experts said.
Sri Lankan wildlife officials have said the giant waves that killed hundreds of thousands of people along the coast of Indian Ocean island seemingly missed the wild beasts,with no dead animals found.
"No elephants are dead,not even a dead hare or rabbit.I think animals can sense disasters.They have a sixth sense.They know when things are happening/5 H.D.Ratnayake,deputy director of Sri Lanka's Wildlife Department,said.
The waves washed floodwaters up to 3 km (about 2 miles) inland at Yala National Park in the southeast,Sri Lankans biggest wildlife reserve and home to hundreds of wild elephants."There has been a lot of evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes.But it has not been proven^ said Matthew van Lierop.an animal behaviour specialist at Johannesburg Zoo.
"There have been no specific studies because you can, really test it in a lab or field setting/ he said.
Other authorities agreed with this judgment.
"Wildlife seem to be able to pick up certain phenomenon,especially birds.There are many reports of birds detecting coming disasters,' said Clive Walker,who has written several books on African wildlife.
Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators （食肉动物）.
The notion of an animal "sixth sense，，is a lasting one that the evidence on Sri Lankans damaged coast is likely to add.
The Romans saw owls as omens of coming disasters and many ancient cultures viewed elephants as sacred （神圣白勺）animals endowed with special powers.
29.It can be inferred from the first paragraph that _____ ・
A.after the Indian Ocean tsunami scientists are sure of an animal “sixth sense"
B.before the Indian Ocean tsunami scientists didn't believe in an animal "sixth sense"
C.before the Indian Ocean tsunami scientists had some idea of an animal "sixth sense'，
D.the Indian Ocean tsunami has offered the only proof for an animal "sixth sense5' 答案:c
解析:从第一段的"adding weight to the notion they possess a 'sixth sensefor disasters"可知，在印度洋海啸发生之前，科学家们就认为动物有第六感觉。

30.The author quoted Clive Walker's words to _____ ・
A.throw doubt on an animal "sixth sense"
B.show the different opinions between Sri Lankan wildlife officials and the authorities
C.show that authorities know better than animal behaviour specialists
D.add proof to an animal "sixth sense"
答案:D
解析:作者引用Clive Walker的话,就是为了进一步证实动物确实有第六感觉，能提前预知危险的到来。

31.Which of the following does not belong to an animal "sixth sense"?
A.Elephants avoiding the coming Indian Ocean tsunami.
B.Dogs barking or birds migrating before volcanic eruptions or earthquakes・
C.Birds detecting coming disasters・
D.Animals relying on the known senses such as smell or hearing to avoid danger.
答案:D
解析:第六感觉指的是视觉、听觉、嗅觉、味觉、触觉这五种官能之外的感觉。

32.The underlined word in the passage probably means _____ .
A.victims
B.signs
C.tests
D.causes
答案:B
解析:该句意为“罗马人曾把猫头鹰视为灾难即将来临的预兆",由此可推知该词的词义。

D
Cell phones with cameras are really a popular way to capture（捕捉）a moment in time,but some
"clever^ students found another use—apturing tests as a way to cheat.
The Magnolia Independent School District in Montgomery County has added camera phones to a list of electronic devices（器具）students are banned from having at school.School officials said the move was made as a preventative（预防的）measure to stop potential©替在的）test cheaters,since students could use the phones to snap（扌白照）pictures of test questions.Another concern was that students might take inappropriate（不合适的）pictures of classmates to later share or post on a website.Cell phones without cameras are allowed on campus,but must be turned off.Camera cell phones will be taken away from students if found on campus,and disciplinary action will be taken,officials said.
Some students were unhappy to hear about the ban/Td be lost without my phone J said Kendall Paul,a Magnolia High School student."All my numbers are in it.Fve never used it to cheat and I don't know anyone who has at our school,so I think it，s kind of stupid： But other students said they saw it all the time at their school.
"You would take a picture of the test and then send it to the next person taking the test J said Melissa Sparks,a student.
"They would send the question and the answerer just the number of the question and the answer.It^s quicker that way/' another student said.
Parents often provide their children with cell phones for use in emergencies（紧急'情况）and to keep in better touch with them/4My Mom wants me to have my phone with me all the time for emergency purpose. So,it goes with me wherever I go J Paul said.
33.Which of the following can probably replace the word "banned" in the second paragraph?
A.cheated ・
B.Allowed.
C.Ordered.
D.Kept.
答案:D 解析:词义猜测题。

根据画线词所在句子的下一句中的as a preventative measure to stop potential test cheaters可推知,ban的含义是"禁止",故选D项。

34.According to this passage,which of the following statements is TRUE?
A.Cell phones carf t be taken into the school.
B.Students，parents are in favour of the ban.
C.Students have different opinions about the ban・
D.Students can use cell phones without cameras freely at school.
答案:c
解析:推理判断题。

由第三段第一句"Some students were unhappy to hear about the ban."可推知，学生们对这条禁令有不同的看法。

35.What does the writer think of the ban?
A.The writer thinks every coin has two sides・
B.The writer thinks that the ban is right.
C.The writer thinks schools shouldn't invade（侵犯）studentsrights.
D.The writer^ opinion is not mentioned in the passage.
答案:D
解析:推理判断题。

从整篇文章来看，作者只是在客观地阐述这一现象，并没有发表自己的见解，故选D项。

Animals in Danger
As we know、a lot of animals are in danger now. Air and water are being polluted so that the environment in which animals live are destroyed.Besides,many trees are being cut down,making many animals lose their homes.Whafs worse,many animals are over hunted for money and are being killed so that some of them are in danger of dying out.
In my opinion,something must be done now.Firstly,natural reserves should be set up to protect the animals. Secondly,all the illegal hunting should be punished.Thirdly,people should be aware of the importance of environmental protection.Only in this way can we save the animals.To save the animals is to save ourselves・。
