【题目】 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.

【题目】

This Family Keeps Their Community Warm by Cutting Firewood for Those in Need

Washington is home to lots of trees—it is the Evergreen State, after all—— and it has lots of fireplaces and wood-burning heaters too. But what if you lived there and couldn’t cut wood or couldn’t afford to pay someone to do it? Luckily, Shane McDaniel and his twin sons, Harrison and Henry McDaniel, are happy to help. The three men cut truckloads of wood—then give it to those m need.

The idea actually started as a father-son relationship project, Shane told msn.com. “I cut wood with my dad. He just loved doing it, " said Shane. He wanted to pass along that feeling, so he and the twins spent the summer cutting. The result was a great wall of wood piled up （堆积）around their house. To buy that much it would cost about $10,000.

It was too much for the McDaniels to use themselves, and when the weather turned cold that November, Shane started thinking of others. He posted online: "IF YOU ARE IN NEED OF FIREWOOD AND CANNOT AFFORD IT, PLEASE PM [personal message] ME! ... If you know someone who BURNS WOOD, please help me and my boys make sure NO ONE GOES COLD IN OUR NEIGHBORHOOD, The response（反应）was immediate. One man offered to donate （捐赠）a wood-burning stove. Others raced over to Shane's house with more wood. One woman, noticing the photo of the McDaniels, started to feel warm in other ways: "I don't need the wood. But I am truly happy for what you have done! ”

Single mom Katelyn Ticer, 29, and her four-year-old daughter depended on a wood-burning stove as their only way of heat, so it was so good to receive a truckload of firewood from the McDaniels. "To get that much wood brought me to tears/' she told msn.com. “ So much stress and worry is off my shoulders. I couldn't be more thankful.

Shane is ready to help more people. “Giving is the reward”, he said. "It has nothing to do with how well it’s received; it's about how much it’s needed.”

【1】What did Shane and his sons do to help their neighbors?

A.They gave firewood to those in need.B.They bought wood-burning stoves.

C.They raised about 10,000 dollars.D.They paid someone to cut wood.

【2】What happened after Shane posted messages online?

A.His family received lots of presents.B.Some people quickly offered to help.

C.Lots of wood piled up around their house,D.The weather suddenly turned freezing cold.

【3】What did Shane think of what he had done to help others?

A.Being needed drives us to give.B.Love is not giving but receiving.

C.Helping others is just helping ourselves.D.It’s better to help people fish than to give them fish.

【题目】

You're not the same person you were as a child. You're not even the same personyou were five years ago. We don't just mean your personality. While we'd love tostart a never-ending discussion over the “true self”，we're here to talk about thecells（细胞）in your body.

Do you know how your fingernails and hair are constantly growing and replacingthemselves? The same thing happens almost everywhere in your body. Your outerlayer of skin makes way for fresher skin, and inside your veins（血管），blood cells turn over to make wayfor fresh blood. It's probably no surprise that these types of cells are short-lived, even some of the mostseemingly permanent（永久的）parts of your body replace themselves over time-including your bones.

Strong as your bones might seem, the cells they're made of won't last a lifetime. Bones are masters at rebuilding themselves, which is why most broken bones can heal on their own into the right shape.

Bones have special cells called osteoclasts（破骨细胞）whose job is to break down bone, even if itisn't broken, and send the minerals into the blood stream. This may sound frighteningly like your bonesare wearing away, but your body knows what it's doing. As osteoclasts break down bone, osteoblasts（成骨细胞）build up new bone to replace the old. By the end of each year, about 10 percent of yourentire adult skeleton will have been rebuilt through this process.

If 10 percent of your bone breaks down every year, it must take about ten years to renew 100percent of your skeleton. That would be a great guess, and it lines up nicely with the medical myth thatthe human body's cells are fully replaced every seven years, but the body is a bit more complex. That10 percent is just an average-some bone grows faster than that, and some grows slower. While someparts of your bone will turn over quickly, other parts will stick around for decades. In fact, most bonecells could live as long as 50 years.

So before you get wrapped up in an identity crisis（危机）about the cells in your body disappearingon you, know that you can lose some hair and you can cut your nails, but the bones of you aren't goinganywhere-at least not very soon and not all at once.

【1】Which of the following is TRUE according to the passage?

A. All the cells in our body are the same ones that we were born with.

B. Our blood cells are constantly growing and replacing themselves.

C. It must take about 10 years to rebuild 100 percent of our skeleton.

D. Osteoblasts can break down skin and also rebuild it over time.

【2】The underlined words "wearing away" probably mean“＿＿”．

A. building upB. taking offC. dying outD. turning on

【3】What does the passage mainly talk about?

A. Our skeleton seems permanent but renews itself over time.

B. It is not surprising that some cells in our body are short-lived.

C. There are two types of cells in our bones: osteoclasts and osteoblasts.

D. We are not the same person we were five years ago because of personality.
