From New Delhi to Beijing,commuters(通勤者)spend a lot of time stuck in traffic.In the United States,Los Angeles(L.A.)and San Francisco tie for second place(并列第二)for having the worst traffic problems.Washington,D.C.is in first place with the worst traffic,according to the Texas A&M Transportation Institute.
In L.A..drivers spend sixty-one hours every year stuck in traffic.These drivers know all too well how bad the traffic can be.Professor Cyrus Shahabi also knows about traffic jams.He said,“It’s a prison of cars.There are too many cars,you can’t move around a lot.I live more than 65 kilometers from my office at the University of Southern California.in L.A..I’m always late even with the help of a navigation(导航)system.I thought it would be appropriate to do something to solve it.”
Therefore,he and PhD student Ugur Demiryurek decided to develop an app for that.The ClearPath app claims to do what other navigation systems cannot.Professor Shahabi says his program uses historical data to predict traffic conditions even before the driver leaves the house.
ClearPath uses two and a half years worth of traffic data from 9,000 sensors(传感器)on the roads of L.A..It also collects information on accidents.
Professor Shahabi says his system does more than just respond to current traffic conditions.With ClearPath,he says,a driver can enter what time he wants to leave on a specific time and date,and ClearPath will give the fastest route.It looks at the entire road network,including surface streets as well as highways,before the driver hits the road.
Ugur Demiryurek says they will launch the free ClearPath app for roads in L.A.in two months.In a year,he and Professor Shahabi hope to have ClearPath available nationwide and overseas once they can collect traffic data from other cities.
“I thought always that L.A.had the worst traffic,but now I know that Shanghai,Beijing,Seoul,Tokyo,believe it or not,Singapore,Hong Kong definitely are examples that can immediately use this.”
The ClearPath app can mainly be used to __________.

A.predict traffic conditions B.kill the boring time
C.avoid the traffic accidents D.collect the current news

What do we know from Professor Cyrus Shahabi’s words in Paragraph 2?

A.Living too far is his main reason for being late for work.
B.Many drivers broke the traffic rules on their way to work.
C.His invention was inspired by his experiences on his way to work.
D.The navigation system he used on his way to work is out of date.

What does Paragraph 5 mainly tell us about ClearPath?

A.Its working principal. B.Its powerful function.
C.Its appearance. D.Its safety.

What can we infer from the last paragraph?
A.L.A.has the worst traffic problems in the world.
B.Around the world ClearPath has been used widely.
C.Many cities can provide the data to do the study.
D.ClearPath will have a big market in the future.

We all know what it is like to be unable to turn your head because of a cold in the muscles of your neck, or because an unexpected twist has made your neck ache. The slightest move makes you jump with pain. Nothing could be worse than a pain in the neck.
That is why we use the phrase to describe some people who give you the same feeling. We have all met such people.
One is the man who always seems to be clapping his hands—often at the wrong time—during a performance in the theater. He keeps you from hearing the actors.
Even worse are those who can never arrive before the curtain goes up and the play begins. They come hurrying down to your row of seats. You are comfortably settled down, with your hat and heavy coat in your lap. You must stand up to let them pass. You are proud of yourself-control after they have settled into their seats…Well, what now…God, one of them is up again. He forgot to go to the men’s room, and once more you have to stand up, hanging on to your hat and coat to let him pass. Now, that is “a pain in the neck”.
Another, well—known to us all, is the person sitting behind you in the movies. His mouth is full of popcorn ; he is chewing loudly, or talking between bites to friends next to him. None of them remain still. Up and down, back and forth, they go—for another bag of popcorn, or something to drink.
Then, there is the man sitting next to you at lunch, smoking. He wants you to enjoy it too, and blows smoke across your food into your mouth.
We must not forget the man who comes into a bus or subway and sits down next to you, just as close as you will let him. You are reading the newspaper and he gets closer so that he can read the paper with you. He may even turn the paper to the next page before you are ready for it.
We also call such a person a “rubber neck”, always getting close to where it does not belong, like neighbors who watch all your visitors. They enjoy learning about your personal business. People have a strong dislike for “rubber necks”. They hate being watched secretly.
Where can you find this passage?

A.In a medicine dictionary. B. in a kids’ story book.
C.In a social science book. D.In a science textbook.

According to the passage, how do you feel when late comers walk back and forth in front of you in a cinema?

A “rubber neck” often __________________ .

A.says bad words behind people.

D.Someone who keeps eating or talking all through the movies.

Dr. Sylvia Earle wants you to stop eating fish. It's not because fish are endangered, though wild fish stocks in many oceans are very low. It's not because they're bad for you, though fish in many areas are exposed to poisonous substances in the water. It’s because they're smart.
"Fish are sensitive, they have personalities," says the marine biologist. For Earle, eating a fish would be like eating a dog or a cat. "I would never eat anyone I know personally."
There's a lot more to fish than meets the eye: they talk to each other, they like to be touched, and they engage in behavior that can seem very human. They can remember things and learn from experience. Earle and a growing number of animal rights activists see these as strong arguments against eating fish altogether.
The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket. "While it may seem conspicuous that fish are able to feel pain, like every other animal, some people think of fish as swimming vegetables," says Dr. Lynne Sneddon. "Really, it's kind of a moral question. Is the enjoyment you get from fishing (or eating fish) more important than the pain of the fish?"
Fishermen and (fried) fish lovers are skeptical. "I've never seen a smart fish," says Marie Swaringen as she finishes off a plate of fish at a Seattle seafood restaurant. "If they were very smart, they wouldn't get caught."
"For years, everyone's been telling us to eat fish because it's so good for us," says another diner. "Now I've got to feel guilty while I'm eating my fish? What are they going to think of next? Don't eat salad because cucumbers have feelings?"
According to Dr. Sylvia Earle, he would stop eating fish as a result of the following reasons EXCEPT ___________ .

A.Fish are sensitive and have personalities
B.He knows fish very well
C.Fish are dangerous to eat because the water is polluted
D.Fish are clever

Dr. Lynne Sneddon describes the behavior of eating fish in a(n) _______ tone.

A.opposed B.optimistic C.indifferent D.supportive

Which word below can take the place of the underlined word “conspicuous” in Paragraph 4?

A.obvious B.easy C.impossible D.necessary

It can be inferred from the last paragraph that _____________ .

A.Human beings should stop eating fish
B.We would feel guilty if we continued eating fish
C.People eat fish because fish are delicious
D.Cucumber is a kind of vegetable or fruit

What was the author’s purpose when writing this passage?

A.To advise people to stop eating fish.
B.To introduce a topic of whether people should eat fish.
C.To advise people not to stop eating fish.
D.To tell us that fish will feel pain when caught and transported.

Debate: Can stricter gun control laws decrease the rate of crimes involving guns?
Yes, because with fewer weapons, you get fewer crimes.
Take a look at the crime rates of countries like the United Kingdom. Their crime rate is very low, compared to ours here in the United States. Just by simply putting stricter laws in place on who can own them, it will greatly reduce the crimes involving guns.

Past Practice
There was an assault weapon(攻击性武器) ban back in 1994 under Bill Clinton. Shootings and crime did not go down for the 10 years when this law was in effect.Criminals do not follow rules.The law only affects those who try to obey the law to arm them to protect themselves.

Wake up, you Americans!
It's hardly surprising that America has one of the highest gun related murder rates of all countries! And of course guns don't kill people, but the more people own guns, the easier it is to get access to one, the higher the chance of people using it to kill somebody is!
In Germany, we have really strict gun laws and only a few people own guns, and obviously we don't need them. There's no reason that a normal citizen would need a gun! Guns are made for one reason only: killing.

More gun control laws, fewer shootings
On the same day as the Sandy Hook tragedy, a man in China entered a primary school with a knife and injured 22 students on December, 14. However, nobody was killed. Compare that to the 26 students and teachers killed at Sandy Hook in Connecticut with a powerful gun.We must learn something from this tragedy.

Gun violence goes up with more gun control
Criminals will take advantage of the situation. They will do whatever they want and take whatever they want and kill whoever gets in their way. They will get guns illegally.Crime rates go up as a result of more gun control, because criminals know you don't have one,and they will kill you as they like.There is no point in banning guns!

Many people think of the brain as a mystery. They don't know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb — and stays that way in the whole life. But new research shows that the brain is more like a muscle — it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That's because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink and you get weaker. That's why people say “Use it or lose it!”
But most people don't know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex (皮层) of the brain are billions of tiny nerve cells, called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do — like speaking a foreign language or doing algebra (代数) — seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals' brains. They found out that animals that lived in a challenging environment were more “perspicacious” — they were better at solving problems and learning new things.
According to the first paragraph,________.

A.the function of our brain is like that of the muscle
B.until now it's impossible to explain the brain's mystery
C.many people believe one's intelligence is naturally determined
D.one's brain grows stronger as the age increases

Training muscles is compared to ________.

A.using the brain
B.connecting things in your brain
C.lifting weights
D.doing research about the brain

What is Paragraph 3 mainly about_________?
The complex structure of the brain.
B. How changes in the muscles affect the brain.
C. The importance of the brain.
D. How the brain becomes stronger by learning new things.
What does the underlined word “perspicacious” in the last paragraph probably mean_________?

A.Strong. B.Smart. C.Popular. D.Active.

The paragraph that follows the passage will most probably talk about _______.

A.the differences between animals’ brains and humans’ brains
B.the relation between human brains and muscles
C.scientists’ findings about animals’ brains
D.how to make your brain smarter through self-development

There are many great movie directors of all time and the following are five of those who have largely impressed audience with their body of work.
As a member of the New Hollywood gang, Francis Coppola is best remembered for The God Father series. His decision to cast Marlon Brando in the lead also met with fierce opposition from the studio bosses. Good sense became popular, and The God Father went on to become one of the most memorable movies ever. Critics may point out that he has become less creative after his seventies, but try as one might, no one can possibly take the place of this great director’s work.
Stanley Kubrick’s movies focus on the themes like sci-fi, horror, dark humor and war. He used symbolism in most of his movies, giving us some wonderful screen visuals, as shown in 2001: A Space Odyssey. His actors in Hollywood complained about the endless number of retakes, but they appreciated the performance he milked out of them. People argue about films like Lolita, A Clockwork Orange and Paths of Glory, but these are now seen as classics.
Steven Spielberg is a great success at the box office, and he is one of the world’s most popular filmmakers today. As the creator of classics like Schindler’s List, Jurassic Park, ET, Indiana Jones series, Jaws, Saving Private Ryan, no one can win his hold over the audience. His critics accuse him of being emotional and over the top, but the fact remains that his movies attract the audience, and set the cash registers ringing.
Woody Allen is a director who directs movies full of crime and hate. This comic genius has given us Annie Hall, Hannah and Her Sisters and Midnight in Paris, which have also become classical. His movies constantly include characters who arouse the audience’s sympathy and laughter at the same time, as they set out on a journey of self-discovery. Hollywood star power has never fazed Allen. Thankfully, awards and honors do not interest him, which results in creativity that is original.
What do the directors mentioned in the passage have in common_______?

A.They are interested in awards for their works.
B.They are members of the New Hollywood gang.
C.They have created a lot of movies taken as classics.
D.They focus their themes on negative side of the society.

B.succeeded in making a great box office
C.became much better at creating classics
