In recent years,American teens 【小题1】（earn） less than stellar（优秀的）scores on the national exam. A new analysis from the Center for American Progress argues for one simple step 【小题2】（help）raise these scores:Start school later in the day.

【小题3】（delay）start time by an hour across the country could improve students math scores up to eight 【小题4】（point）, the analysis says. That's almost one grade level of learning. The idea is that giving sleep-lacking teens more time to sleep 【小题5】 they hit the books will help them learn better.

In the previous study conducted in 2012 , middle school students 【小题6】 switched schedules to start school an hour later saw their test scores increase. And among them the low-performing students saw the 【小题7】（big）increase.

The Center for American Progress considered what would happen if those results 【小题8】（repeat） around the country.

“What we found is the impact 【小题9】 student achievement would be quite large,” Ulrich Boster, a senior fellow at the center, told The Huffington Post. “Starting school later could 【小题10】（significant）improve students' outcomes. ”

How could we possibly think that keeping animals in cages in unnatural environments -mostly for entertainment purposes - is fair and respectful? Zoo officials say they are concerned about animals. However, most zoos remain “collections” of interesting “things” rather than protective habitats.
Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes. Zoos claim to educate people and save endangered species, but visitors leave zoos without having learned anything meaningful about the animals’ natural behavior, intelligence, or beauty. Zoos keep animals in small spaces or cages, and most signs only mention the species’ name, diet, and natural range.
The animals’ normal behavior is seldom noticed because zoos don’t usually take care of the animals’ natural needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise. This results in unusually and self-destructive behavior called zoochosis. A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.
Furthermore, most animals in zoos are not endangered. Captive breeding (圈养繁殖) of endangered big cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out. In fact, baby animals also attract a lot of paying customers. Haven’t we seen enough competitions to name baby animals?
Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them. Instead of supporting zoos, we should support groups that work to protect animals’ natural habitats.
【小题1】How would the author describe the animals’ life in zoos?

A．Dangerous.	B．Unhappy.
C．Natural.	D．Easy.

【小题2】In the state of zoochosis, animals _________.

A．remain in cages	B．behave strangely

【小题3】What does the author try to argue in the passage?

A．Zoos are not worth the public support.

B．Zoos fail in their attempt to save animals.

C．Zoos should treat animals as human beings.

D．Zoos use animals as a means of entertainment.

【小题4】The author tries to persuade readers to accept his argument mainly by _________.

A．pointing out the faults in what zoos do

B．using evidence he has collected at zoos

C．questioning the way animals are protected

D．discussing the advantages of natural habitats

Forget Cyclists, Pedestrians are Real Danger
We are having a debate about this topic. Here are some letters from our readers.
■Yes, many cyclists behave dangerously. Many drivers are disrespectful of cyclists. But pedestrians are probably the worse offenders.
People of all ages happily walk along the pavement with eyes and hands glued to the mobile phone, quite unaware of what is going on around them. They may even do the same thing while crossing a road at a pedestrian crossing or elsewhere. The rest of us have to evade (避让) them or just stand still to wait for the unavoidable collision.
The real problem is that some pedestrians seem to be, at least for the moment, in worlds of their own that are, to them, much more important than the welfare of others.
——Michael Horan
■I love the letter from Bob Brooks about cyclists (Viewpoints, May 29). I am afraid they seem to think they own the roads.
I was walking across Altrincham Road one morning when a cyclist went round me and on being asked what he was doing he shouted at me.
The government built a cycle lane on the road but it is hardly used.
The police do nothing. What a laugh they are!
The cyclists should all have to be made to use the cycle lanes and wear helmets, fluorescent (发荧光的) jacket and lights at night and in the morning they should pay some sort of tax and be fined for not wearing them.
——Carol Harvey
■Cyclists jump on and off pavements (which are meant for pedestrians), ride at speed along the pavements, and think they have a special right to go through traffic lights when they are on red.
I was almost knocked down recently by a cyclist riding on the pavement when there was a cycle lane right next to him.
Other road users, including horse riders, manage to obey the rules so why not cyclists?
It's about time they had to be registered and insured, so when they do hit a pedestrian or a vehicle, or cause an accident, at least they can be treated and there might be an opportunity to claim.
——JML

“Can I get a light?”This question is the commonest among smokers. What if this question is to come from an unusual source? The National Health Promotion Foundation uploaded an anti-smoking advertisement onto YouTube. The anti-smoking ad has quickly been known as the“most powerful anti-smoking ad”.

The anti-smoking video, called the “Smoking Kid”, features children walking up to adult smokers asking for a light. The children in the ad are actors but the adults smoking are unsuspecting participants in the project.

The video begins with the statement “Adults know that smoking is harmful, but don’t remind themselves of this fact”. Once a “smoking kid” approaches the adults, every adult asked is shocked that the child with a cigarette in his hand is asking for a light. The first adult starts by saying “I’m not giving it to you” and the video goes on to state “every adult filmed said no and reminded the children that smoking is bad”.

Before going away, the kid hands each adult a booklet after being turned down for a light. The booklet says, “You worry about me, but why not about yourself?”Each adult looks around for the child as their faces are filled with confusion and discomfort.

The video shows that a few of the smokers quickly throw away their cigarettes or put their cigarettes away, showing that this experiment was effective at that moment.

The most influential element in the ad isn’t the use of children or the responses from the smoking adults. It comes down to something much simpler than that. Why is it that we worry about other people, forgetting to worry about ourselves?

【小题1】The underlined word “unsuspecting”（in Para. 2）probably means“________”.
