When baby turtles first come out of eggs, they head to the sea by nature. The beach surface goes down, which is one directional clue they follow. Another is light: The horizon (地平线) over the sea is brighter than the horizon over land.

But lights from towns and beach developments can confuse the baby turtles. The sky shining above a city can mislead them to wander. And particularly bright lights can draw them away from the sea.

You’d think the extra time crawling (爬行) might wear out baby turtles, which need energy　 once they get in the water to swim for about a day to get to their destination in the sea. In a normal trip from nests to waves, the babies build up chemicals that show they have been pushing themselves.

Some researchers took the baby turtles to a lab, where they ran on a treadmill and swam in a tank while their blood and breathing were monitored. The finding is surprising: even after hours of crawling, the turtles were fine by all measures and swam as well as turtles that didn't have an extra crawling period.

The reason is that they often stop while crawling if they are doing U for a long time, unlike the disturbed trip they make when heading straight to the water. So misled turtles are not worn out.

But the misleading lights are still a problem for the babies. The longer they spend on the beach wandering, the more they are exposed to natural enemies. They can also end up losing their lives in the heat of the sun.

1.What attracts the baby turtles away from the sea?

A.Bright lights. B.Vast beaches.

C.Buildings in cities. D.Noises from towns.

2.What does the underlined word “they” refer to in paragraph 3?

A.Chemicals. B.Nests.

C.Waves. D.Baby turtles.

3.Why don’t the baby turtles feel exhausted after long crawling?

A.They travel by night. B.Their trip is undisturbed.

C.They take frequent breaks. D.They are refreshed by city lights.

4.What may happen to the baby turtles exposed to misleading lights?

A.They are in great danger.

B.They avoid their natural enemies.

C.They will wander on the beach for a while.

D.They are more likely to find the destination.

For hundreds of millions of years, turtles (海龟) have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings (幼龟) down to the water’s edge lest (for fear that) they become disoriented by headlights and crawl towards a motel parking lot instead. A formidable wall of bureaucracy has been erected to protect their prime nesting on the Atlantic coastlines. With all that attention paid to them, you’d think these creatures would at least have the gratitude not to go extinct (die out).

But Nature is indifferent to human notions of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species of North Atlantic turtles, notably loggerheads, which can grow to as much as 400 pounds. The South Florida nesting population, the largest, has declined by 50% in the last decade, according to Elizabeth Griffin, a marine biologist with the environmental group Oceana. The figures prompted Oceana to petition the government to upgrade the level of protection for the North Atlantic loggerheads from “threatened” to “endangered”— meaning they are in danger of disappearing without additional help.

Which raises the obvious question: what else do these turtles want from us, anyway? It turns out, according to Griffin, that while we have done a good job of protecting the turtles for the weeks they spend on land (as egg-laying females, as eggs and as hatchlings), we have neglected the years spend in the ocean. “The threat is from commercial fishing,” says Griffin. Trawlers (which drag large nets through the water and along the ocean floor) and longline fishers (which can deploy thousands of hooks on lines that can stretch for miles) take a heavy toll on turtles.

Of course, like every other environmental issue today, this is playing out against the background of global warming and human interference with natural ecosystems. The narrow strips of beach on which the turtles lay their eggs are being squeezed on one side by development and on the other by the threat of rising sea levels as the oceans warm. Ultimately we must get a handle on those issues as well, or a creature that outlived the dinosaurs (恐龙) will meet its end at the hands of humans, leaving our descendants to wonder how creature so ugly could have won so much affection.

1.We can learn from the first paragraph that ________.

A．human activities have changed the way turtles survive

B．efforts have been made to protect turtles from dying out

C．government bureaucracy has contributed to turtles’ extinction

D．marine biologists are looking for the secret of turtles’ reproduction

2.What does the author mean by “Nature is indifferent to human notions of fairness” (Line 1, Para. 2)?

A．Nature is quite fair regarding the survival of turtles.

B．Turtles are by nature indifferent to human activities.

C．The course of nature will not be changed by human interference.

D．The turtle population has decreased in spite of human protection.

3.What constitutes a major threat to the survival of turtles according to Elizabeth Griffin?

A．Their inadequate food supply.

B．Unregulated commercial fishing.

C．Their lower reproductively ability.

D．Contamination(pollution) of sea water

4.How does global warming affect the survival of turtles?

A．It threatens the sandy beaches on which they lay eggs.

B．The changing climate makes it difficult for their eggs to hatch.

C．The rising sea levels make it harder for their hatchlings to grow.

D．It takes them longer to adapt to the high beach temperature.

When Jane put out the idea of homeschooling to her parents, the first reaction they gave was, “You are cutting the child off the world.” “Did the child really get cut off or did the child socialize better?”

The moment we hear of homeschooling, we think the child will have no opportunities to interact with their peers. However, in my friend’s opinion, we forget that when attending a regular school, the child is not into socializing all the while. The child is restricted to so many other activities. Studies take a major role in a child’s life. The child hardly has the time to interact at school.

The child might be meeting and studying along with many peers; however, how many kids interact with all the kids in a class? But in homeschooling system, as my friend mentioned, the kid has all the time and can plan his day accordingly. During the day the child studies just like other school-going kids but with no burden of homework and project work, the child has so much free time in the evening as to effectively interact and play with peers. The quality time the child spends in education is really impressive.

Homeschooled kids have the opportunity to socialize more often as they have a lot of time in their hands. They can also make socializing a regular habit. Just as my friend said, her child goes to a neighboring park almost every day and has a set of friends who go there daily. Other children get back home to finish off homework and project work whereas her child who is already through with studies gets the opportunity to spend time with family members.

When I heard this, I really felt how lucky the child was. Definitely the child had a better opportunity to socialize when compared with my kid. However, I might not consider homeschooling for my kid, as I am so used to the conventional schooling system and feel regular schooling the safest bet.

1.The author’s purpose in writing the passage is to _________.

A. express his views on homeschooling

B. explain what homeschooling is

C. share his ways of teaching his children

D. promote homeschooling

2.What is the biggest advantage of homeschooled children?

A. They will become braver.

B. They can be more popular.

C. They can socialize better.

D. They will know how to arrange time.

3.What do we know about homeschooled children?

A. They don’t interact with their peers often.

B. They have more spare time to play.

C. They are restricted to certain activities

D. They can’t gain enough knowledge.

4.How does the passage mainly develop?

A. By following the order of importance.

B. By following the order of time.

C. By making comparisons.

D. By presenting data.

The sun was just coming up when I headed out to work last May at 6 a.m. Not quite dark but dark enough to need my headlights. I turned onto one of the lonely rural country roads.

Maybe it was because I was listening to the radio, maybe it was because I was already thinking about some projects at work, that I didn’t spot the dark object on the road until I was too late. I ran over it and felt the back left tire pull, and then sink. I stopped and got out of the car.

No mystery here---- my back left tyre was cut like a loaf of bread. Back 50 yards was a piece of sharp iron I had run over. I had never changed a tyre. I looked up the road. Not a car in either direction. The nearest service station was miles away. I threw up my hands. Then I remembered---- my cell phone! I powered it up before realizing, I didn’t know who to call.

Wouldn’t you know it, I spotted a car coming from the opposite direction. The driver slowed as he approached. I guessed he could see I was in trouble. He stopped his car, got out and immediately saw the trouble. “Madam, would you like me to change that tyre for you?” he asked. The man couldn’t have been more friendly. I was frightened out there and he put me completely at ease. “There,” he said, after putting on the spare, “you are all set to go.”

“Good thing for me that you were driving this way,” I told him, as I climbed back into my car.

“Funny you should say that,” he said. “Just like you, I was heading to work, but my job is in the opposite direction. I made a wrong turn at some point. I don’t know what I was thinking.”

1.The writer didn’t notice the object on the road because ______.

A. it was rather dark then                 B. she didn’t use her headlights

C. there was much traffic                  D. she was careless when driving

When a dirty and untidy orange cat showed up in the prison yard，I was one of the first to go out there and pet it．I hadn’t touched a cat or a dog in over 20 years．I spent at least 20 minutes，knelt down behind the kitchen as the cat rolled around，relaxed．What he was expressing outwardly, I was feeling inwardly．It was an amazing bit of grace to feel him under my hand and note that I was reaching a li fe or another creature with something as simple as my care．

Over the next few days，there were other prisoners responding to the cat．Every yard period，a group of prisoners gathered t here．They stood around talking and taking turns petting the cat．These were guys you wouldn’t usually find talking to each other．Several times I saw an officer in the group，not chasing people away, but just watching and seeming to enjoy along with the prisoners．Bowls of milk and water appeared along with bread, wisely placed under the edge of the dustbin to keep the birds from getting it．

The cat was obviously homeless and in pretty bad shape．People said that the cat came to the right place．He's getting treated like a king．This was true．but as I watched I was also thinking about what the cat was doing for us．There was a lot of talk about what's wrong with prisons in America．We need more programs．We need more psychologists or treatment of various kinds．Some may even talk about making prisons more kind．But I think what we really need is a chance to practise our own kindness．Not receive it，but give it．After more than two decades here，I know kindness is not a value that's encouraged．It's often seen as a weakness．

Instead，the culture encourages keeping your head down，minding your own business，and never letting yourself be weak．

The cat did my heart good to see the effect he had on me and the men here．By simply saying，”I need some help here”，he did something important for us．He needed us．And we needed to be needed．I believe we all do．

WASHINGTON　　 The head of the World Bank says for the first time in human history, it is possible to end poverty around the world. Jim Yong Kim told a Washington audience Tuesday, he wants to make ending world poverty by 2030 a top goal for the bank and governments around the world.

World Bank President Jim Yong Kim says that the problems of poverty, hunger and inequality are wide, urgent and a matter of survival of millions.

“We know that despite the great successes of the last decade, there are still about 1.3 billion people living in extreme poverty, 870 million who go hungry every day, and 6.9 million children under five dying every year,” he said.

But Kim told a Washington audience that the previous successful efforts to cut the number of people living in extreme poverty by half give them hope.

“We are at an auspicious moment in history, when the successes of past decades and an increasingly favourable economic outlook combine to give developing countries a chance－for the first time ever－to end extreme poverty within a generation,” he said in a speech at Georgetown University. “Our duty now must be to ensure that these favourable circumstances are matched with deliberate decisions to realize this historic opportunity.”

Kim says success will require increasing the speed of economic growth, particularly in South Africa and South Asia.

But he warned that civil unrest could happen if economic growth does not help people at all income levels, and also include women and youth．

Kim says that the World Bank and other development agencies will have more resources to get this job done right. “Meeting this 2030 goal will take extraordinary effort,” he said.

However, Kim warned that all the progress in fighting poverty could be destroyed by climate disasters unless the nations of the world do more to prevent climate change.

1.In the opinion of Jim Yong Kim, world poverty _____．

A. is difficult but hopeful to end by 2030

B. exists only in Africa and Asia

C. is not quite hard to end by 2030

D. will be sure to disappear by 2030

2.Which of the following gives Jim Yong Kim the hope to end world poverty?

A.Economic growth is increasing in developing countries．

B.Great successes have been achieved in science and technology．

C.A decreasing number of people are living in poverty．

D.All countries have started to fight poverty．

3.The underlined word "auspicious" in Paragraph 5 most probably means "_____"．

A. unforgettable　　　　　　　　　　　　     B. lucky

C. disappearing　　　　　　　　　　　　     D. important

4.What’s the passage mainly about?

A.The key of ending world poverty is preventing climate change.

B.A top goal－ending world poverty will possibly be achieved by 2030.

C.The success of ending poverty－economic growth.

D.The progress in fighting poverty.
