【题目】It’s 5pm on a Friday and I'm standing in a coffee shop above Shibuya crossing - one of the most busiest place in Japan where more than a thousand of Tokyo’s smartly dressed people gather at eight points, ready to cross - then rush straight for each other. It looks like they must bump into each other, but It’s amazing that they all manage to reach the other side safely.

But the real reason I'm here is that I want to see people crash. I want businessmen to knock into each other, their umbrellas flying off their arms, and uniformed schoolchildren hitting grannies. Why may I see this now, but wouldn't have had the chance even a year ago? It’s very simple - smartphones.

Smartphone use is booming in Japan. In 2012, only about a quarter of Japanese used them, most being perfectly happy with their everyday mobiles. But now more than half of all Japanese now own a smartphone and the number is rising fast. But with that rise has grown another phenomenon - the smartphone walk. Those people who're staring at a phone screen adopt this kind of pace- their head down, arms outreached, looking like zombies(僵尸)trying to find human prey(猎食).

Surprisingly, an American named Michael Cucek who has lived here for more than 20 years told me smartphone walk probably wouldn’t be a long-term problem. Japanese phone manner is in fact better than anywhere else in the world - hardly anyone speaks on their phones on trains, and teenagers wouldn't dare broadcast music out of one. If things got truly bad at Shibuya, the police would just start shouting at people to look up.

But really, is the smartphone walk such an annoying problem? There's only one way to find out. So I leave the coffee shop, head down to the crossing and start typing an email, promising myself I won't look up until I get to the other side. When they start walking past me, it's my time to cross. As I step forward, the experience quickly becomes nervous - legs jump in and out of my vision without warning, while shopping bags fly towards my face before being pulled away at the last moment. I'm sure I'm going to get hit, but after a few seconds I relax. It’s OK. Everyone's reacting for me.

I expect to see two smartphone walkers just like me. But instead I find a young couple, very much in love and very much refusing to let each other’s hands go just to give way to a fool on his smartphone. The girl gives me such a look of dislike that I quickly apologize and rush round them. That look was enough to ensure I'll never be smartphone walking again.

【题目】One morning, Ann’s neighbor Tracy found a lost dog wandering around the local elementary school. She asked Ann if she could keep an eye on the dog. Ann said that she could watch it only for the day.

Tracy took photos of the dog and printed off 400 FOUND fliers(传单), and put them in mailboxes. Meanwhile, Ann went to the dollar store and bought some pet supplies, warning her two sons not to fall in love with the dog. At the time, Ann’s son Thomas was 10 years old, and Jack, who was recovering from a heart operation, was 21 years old.

Four days later Ann was still looking after the dog, whom they had started to call Riley. When she arrived home from work, the dog threw itself against the screen door and barked madly at her. As soon as she opened the door, Riley dashed into the boys’ room where Ann found Jack suffering from a heart attack. Riley ran over to Jack, but as soon as Ann bent over to help him the dog went silent.

“If it hadn’t come to get me, the doctor said Jack would have died,” Ann reported to a local newspaper. At this point, no one had called to claim the dog, so Ann decided to keep it.

The next morning Tracy got a call. A man named Peter recognized his lost dog and called the number on the flier. Tracy started crying, and told him, “That dog saved my friend’s son.”

【题目】Cell phones with cameras are really a popular way to capture a moment in time, but some “clever” students found another use—capturing tests as a way to cheat.

The Magnolia Independent School District in Montgomery County has added camera phones to a list of electronic devices (器具) students are banned from having at school.

School officials said the move was made as a preventative measure to stop potential (潜在的) test cheaters, since students could use the phones to snap pictures of test questions. Another concern was that students might take inappropriate (不合适的) pictures of classmates to later share or post on a website. Cell phones without cameras are allowed on campus, but must be turned off. Camera cell phones will be taken away from students if found on campus, and disciplinary action will be taken, officials said.

Some students were unhappy to hear about the ban. “I’d be lost without my phone,” said Kendall Paul, a Magnolia High School student. “All my numbers are in it. I’ve never used it to cheat and I don’t know anyone who has at our school, so I think it’s kind of stupid. But other students said they saw it all the time at their school.

“You would take a picture of the test and then send it to the next person taking the test,” said Melissa Sparks, a student.

“They would send the question and the answer, or just the number of the question and the answer. It’s quicker that way,” another student said.

Parents often provide their children with cell phones for use in emergencies(紧急情况)and to keep in better touch with them. “My Mom wants me to have my phone with me all the time for emergency purpose. So, it goes with me wherever I go, Paul said.

【1Which of the following can probably replace the words “banned from having” in the second paragraph?

A. Forbidden to have. B. Allowed to have.

C. Ordered to have. D. Kept having.

2According to this passage, which of the following statements is TRUE?

A. Cell phones can’t be taken into the school.

B. Students’ parents are in favor of the ban.

C. Students have different opinions about the ban.

D. Students can use cell phones without camera freely at school.

3What does the writer think of the ban?

A. The writer thinks every coin has two sides.

B. The writer thinks that the ban is right.

C. The writer thinks schools shouldn’t invade (侵犯) students’ rights.

D. The writer’s opinion is not mentioned in the passage.

4The underlined word “it” in Paragraph 4 refers to the fact that _________.

A. some students cheat in exams

B. some students get lost without their camera cell phones

C. the School District’s ban is stupid

D. some students cheat in exams with camera cell phones
