PLAYA GRANDE, COSTA RICA----This resort town was long known for Leatherback Sea Turtle(棱皮龟)National Park, nightly turtle beach tours and even a sea turtle museum. However, on a beach where dozens of turtles used to nest on a given night, scientists spied only 32 leatherbacks all of last year.

With leatherbacks threatened with extinction, Playa Grande’s turtle museum was abandoned (抛弃)three years ago and now sits among a sea of weeds. And the beachside ticket office for turtle tours was washed away by a high tide in September. “We do not promote that as a turtle tourism destination any more because we realize there are far too few turtles to please,” said Alvaro Fonseca, a park ranger.(管理员)

Even before scientists found temperatures going up over the past decade, sea turtles were threatened by beach development, drift net fishing and Costa Ricans’ interest in eating turtle eggs. But climate change may cause the most serious harm to an animal that has lived in the Pacific for 150 million years.

Sea turtles are sensitive to numerous effects of warming. They feed on reefs, which are dying in hotter seas. They lay eggs on beaches that are being covered by rising seas and more violent waves.

More uniquely(独特地), their gender is determined not by genes but by the egg’s temperature during development. Small rises in beach temperatures can result in all-female populations, obviously problematic for survival. If the sand around the eggs hits 30 degrees Celsius, the gender balance shifts to female; at about 32 degrees they are all female. Above 34, you get boiled eggs.

On some nesting beaches, scientists are artificially cooling nests with shade or irrigation and trying to protect broader areas of coastal property from development to ensure that turtles have a place to nest as the seas rise.

Why does the resort town stop promoting its turtle tourism?

A.It decides not to disturb the turtles’ normal life.

B.Tourists have lost interest in watching turtles.

C. There are only very few turtles now.   D. The turtle museum was destroyed by a high tide.

Which of the following is the major factor in the turtles’ endangerment?

A. The locals’ eating habit.   B. Drift net fishing.  C. Beach development. D. Global warming.

The underlined word “gender” in Paragraph 5 means ____.

A. the sex of turtles   B. the habit of turtles   C. the weight of turtles   D. the kind of turtles

We learn from the last paragraph that scientists ____.

A. are doing research on the sea rise   B. are moving turtles to new homes

C. are protecting turtles’ nests        D. are going rid of sea weeds

The passage intends to ____.

A. introduce a special kind of sea turtle   B. explain the mystery of turtles’ eggs

C. show the dangers a certain kind of sea turtle is facing  

D. attract more visitors to a sea turtle museum

Sea turtles come in many different sizes, shapes and colors. The shell of each sea turtle species is different in length, color, shape and the arrangement of the scales(鳞片).
Sea turtles do not have teeth but use their jaws (下巴)to eat. Their sense of smell is excellent. Their eyesight underwater is good, but they have near-sighted eyes out of water. Their special bodies make them adapt to life at sea. However, sea turtles maintain(保持) close ties to land.
Female sea turtles have to go to the seaside to lay their eggs in the sand; therefore, all baby sea turtles begin their lives on land. Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest, largely because they can be found most easily. After decades of studying sea turtles, much has been learned about. However, many mysteries(谜) still remain.
Researchers do not yet know how long baby turtles spend in the open sea, or exactly where they go. People believe they spend their earliest years floating in the sea, where they do little more than eat and grow. Once turtles reach dinner-plate size, they appear at feeding grounds in waters near the shore. They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles, depending on the species. There is no way to know the age of a sea turtle from its physical appearance. It is believed that some species can live for over 100 years.

As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights. They want their homes more comfortable and they want their streets sage. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.

Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attracted meteor shower(流星雨). The area was short of homes, street lights and traffic. If I did that today, I wouldn’t be able to see the meteor shower as well, and I would surely be run over by a car.

Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you’ve ever taken a flight at night, the view is beautiful, but you must remember that all the light you see is wasted electricity. The crew of the space shuttles see an even bigger picture of how extensive the wasted electricity is worldwide.

Additionally, electricity needs to be generated, and the generation of electricity creates pollution by giving off greenhouse gases. This affects the air we breathe and our quality of life.

Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny sea turtle hatchlings become lost and follow lights on the shore instead of heading towards the sea.

    Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution. 

1.The author tells the story in the second paragraph mainly to _________.

     A. remember the past beauty of the town.

     B. stress the advantages of less pollution

     C. show the great changes of the town

     D. prove the bad effects of light pollution

2.In the passage the author advises people _________.

     A. to try to reduce unnecessary light.

     B. not to ignore the beauty around.

     C. to set proper light for animals

     D. not to destroy the animal’s living conditions.

3.What can be inferred from the passage?

     A. Light pollution is difficult to deal with.

     B. Light pollution is a threat to some animals.

     C. Light pollution has nothing to do with global warming

     D. Astronauts can’t see clearly in space due to light pollution.

4.What is most likely to be discussed in the paragraph which follows the last paragraph?

     A. The author’s contribution to light pollution

     B. Other sources of light pollution

     C. Ways of reducing light pollution

     D. More bad effects of light pollution
