LONDON (Reuters) Ecotourism is causing a lot of damage to wildlife and may be endangering the survival of the very animals people are flocking to see, according to researchers.
Biologists and conservationists are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying.
"Evidence is growing that many animals do not react well to tourists in their backyard，” New Scientist magazine said.
The immediate effects "researchers have noticed are changes in behavior, heart rates. or stress hormone levels but they fear it could get much worse and over the long term “ could endanger the survival of the very wildlife they want to see. ”
Although money produced through ecotourism, which has been growing at about 10-30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union (IUCN) and some governments fear not all projects are audited（审计） and based on environmentally friendly policies，according to the magazine.
Transmission of disease to wildlife，or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding，” said Philip Seddon , of the University of Otago in Dunedin, New Zealand.
Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by colorists are producing smaller babies.
Conservationists are now calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started.
“The animals’ welfare should be very important because without them there will be no ecotourism，” said Rochelle Constantine of the University of Auckland in New Zealand

You have probably heard of the Mozart effect. It’s the idea that if children or even babies listen to music composed by Mozart, they will become more intelligent. A quick Internet search reveals plenty of products to assist you in the task. Whatever your age there are CDs and books to help you taste the power of Mozart’s music, but when it comes to scientific evidence that it can make you more clever, the picture is more mixed.
The phrase “the Mozart effect” was made up in 1991, but it was a study described two years later in the journal Nature that sparked real media and public interest about the idea that listening to classical music somehow improves the brain. It is one of those ideas that sound reasonable. Mozart was undoubtedly a genius himself; his music is complex and there is a hope that if we listen to enough of it ,we’ll become more intelligent.
The idea took off, with thousands of parents playing Mozart to their children, and in 1998 Zell Miller, the Governor of the state of Georgia in the US, even asked for money to be set aside in the state budget so that every newborn baby could be sent a CD of classical music. It was not just babies and children who were exposed to Mozart’s music on purpose, even an Italian farmer proudly explained that the cows were played Mozart three times a day to help them to produce better milk.
I’ll leave the debate on the impact on milk yield to farmers, but what about the evidence that listening to Mozart makes people more intelligent? More research was carried out but an analysis of sixteen different studies confirmed that listening to music does lead to a temporary improvement in the ability to handle shapes mentally, but the benefits are short-lived and it doesn’t make us more intelligent.
小题1:What can we learn from paragraph 1?

A．Mozart composed many musical pieces for children.

B．Children listening to Mozart will be more intelligent.

C．There are few products on the Internet about Mozart’s music.

D．There is little scientific evidence to support Mozart effect.

小题2:Why did many people believe in the idea of Mozart Effect?

A．Because a study described it in the journal Nature.

B．Because Mozart himself was a genius.

C．Because Mozart’s music is enjoyable.

D．Because Mozart’s music makes people relaxed.

小题3:The underlined sentence in paragraph3 suggests that .

A．people were strongly against the idea

B．the idea was accepted by many people

C．Mozart played an important part in people’s life

D．the US government helped promote the idea

小题4:What is the author’s attitude towards the Mozart effect?

A．Favorable

B．Objective

C．Doubtful

D．Positive

小题5:What would be the best title for the passage?

A．Listening to Mozart , necessary?	B．What music is beneficial?
C．What is the Mozart effect?	D．To be or not to be?

An eighteen-year-old high school student from Utah won the top prize in the Intel Science Talent Search in the United States. The winner received a computer and a scholarship for a college education.
More than 1,500students from across the country entered projects in the competition this year. Their research included chemistry, medicine, physics, mathematics, engineering, and computer science-almost every area of science.
Forty students were invited to Washington, D.C. for the final judging. A group of scientists judged them on their research abilities, critical thinking skills and creativity. The judges also questioned the students about scientific problems before deciding on the winners.
The top winner received 100,000 dollars for college. Shannon Babb of American Fork High School studied the water quality of tile Spanish Fork River in Utah for six years.

The kiwi bird
The kiwi bird is a flightless bird，about the size of a chicken. It sleeps during the day and is active at nighttime. It has a long beak that is onethird the length of its body, and its beak actually has nostrils (鼻孔) at the end. The kiwi is the only bird with this feature. Another unique feature of the kiwi is that it has no tail. It has thick brown hairlike feathers. This bird has many physical features unlike any other bird on earth.
Kiwi birds have been called a genetic leftover. Their characteristics seem very odd to us probably due to the fact that they haven"t evolved much at all. They are suspected to be about 8 million years old. That"s 7 million years older than humans. Due to New Zealand"s isolated environment, it has been safe from predators(食肉动物) and hasn"t needed to do much adapting. They just hang around.

A kiwi is almost blind; it can see about six feet at night and around two feet during the day，so when it comes to hunting the kiwi is not well equipped.It uses the nostrils on its beak to find its food and then picks up the worms with its beak.
The kiwi bird is native of New Zealand.It is the island country"s national bird, and is rare anywhere but here and a few Pacific island neighbors. Of course，it is available for viewing at certain zoos.It has stayed in its native land due to the facts that it is an isolated island and that kiwis can"t fly.
Kiwi birds are extremely unique in the bird world. Though they are the size of chickens, they lay eggs the size of ostrich eggs, weighing around a pound each.Their enormous eggs are the largest in the bird world, compared to their bodies. These birds were named after their distinctive shrill cry “keewee keewee”．
