【題目】 A sea turtle climbed out of the ocean. It was just before midnight. It arrived to lay eggs.

Sea turtles have been doing this for 200 million years. Sea turtles lived at the time as the dinosaurs.

The sea turtle had to survive plastic rubbish, fish nets and oil spills to get here. There is another danger. The Earth has been getting warmer. This makes the sand hot. Warm sand makes the turtle eggs hatch (孵化) as females (雌性).

This is a problem. Female sea turtles are very important because they lay eggs. But male turtles are also needed to help make babies. Without enough males, sea turtles could die out.

Every year, sea turtles swim to Cape Verde. It is a country in West Africa. About 30000 sea turtles nest (筑巢) there. This is one-sixth of all of Earth’s nesting sea turtles.

Scientists from Great Britain studied the turtles there. They found 21 out of 25 young turtles were females.

“Males here will die out in 20 to 30 years.” said Adolfo Marco Llorente. He is studying the turtles on Boa Vista. It is one of Cape Verde’s island. Without males, the turtles cannot have more babies.

Businesses on Cape Verde are worried. Tourists come to see the sea turtles. The tourists buy local things like pottery. They would lose money if turtles died out.

Scientists have looked at sea turtles in other warm areas. There are more female turtles there, too.

84% of sea turtles hatchlings in Cape Verde are now female

This is worrying, so scientists have found ways to keep the turtle nests cool. Keeping the eggs cool means more male turtles can be hatched. One way is to move the eggs under the trees or bushes. Scientists have also put the eggs into smaller groups. Many eggs close together can heat up.

Llorente’s team collects the eggs in a bag. Then they bring them to a place on the beach behind a fence. The fence keeps animals away that want to eat the eggs. It also lets the scientists watch the temperature of the eggs.

【1】Which sentence from the passage is the topic sentence?

A.Every year, sea turtles swim to Cape Verde.

B.Without enough males, sea turtles could die out.

C.The fence keeps animals away that want to eat the eggs.

D.The past five years have been the hottest years on Earth.

【2】How does temperature hurt turtles?

A.Higher temperatures make turtle eggs hatch as females.

B.Turtle eggs will not hatch if the temperature is too cold.

C.Turtle eggs are hatched as males when it cools down.

D.A female turtle lays more eggs if it is warmer.

【3】Why do businesses on Cape Verde need turtles to hatch each year?

A.Because the companies earn money from selling turtles.

B.Because people there enjoy swimming with turtles.

C.Because turtles bring tourists and money to the area.

D.Because it helps to keep the temperatures cool.

【4】Which place has the highest percentage (百分比) of female turtles?

A.San Diego.B.Boca Raton.C.Cape Verde.D.Great Barrier Reef.

【5】Which is the way to help more baby boy turtles be hatched?

A.Put the turtle eggs in groups.

B.Move the eggs to cooler places.

C.Collect and keep the eggs in bags.

D.Watch and help the turtles lay eggs.
