Are you carrying too much on your back at school? I’m sure lots of children of your age will say “Yes”. Not only do the students in China have this problem, but children in the United States also have heavy school bags.

Doctors are starting to worry that younger and younger students are having back and neck problems as a result of school bags being too heavy for them.

“It’s hard for me to go upstairs with my bag because it’s so heavy,” said Rick Hammond, an 11-year-old student in the US.

Rick is among students who have common school bags with two straps (带子) to carry them, but many other students choose rolling bags(拉杆包).

But even with rolling bags, getting upstairs and buses is still a problem for children. Many of them have hurt their backs or necks because of the heavy school bags.

But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight.

Scott Bautch, a doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don’t stay with over 15%, because their bodies are still growing. “Children are losing their balance and falling down with their school bags,” he said.

Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.

One of the best answers is, as some children said, to have no homework at all!

1.From the passage we can know that .

A. only children in China carry too heavy school bags

B. both children in China and the US carry too heavy school bags

D. only children in the US carry too heavy school bags

2.If a child carries a heavy school bag, .

A. his back or neck will be hurt B. his head and arms will be hurt

C. his hands will be hurt D. his feet will be hurt

3.According to Scott Bautch, if a child in Grade 5 weighs about 30 kilos, the school bag he carries should not be over ________.

A. 5 kilos B. 3 kilos

C. 5.5 kilos D. 4.5 kilos

4.Some students think the best answer to this problem is that .

A. they should have a little homework to do after they get home

B. their teachers had better not ask them to do any homework

C. they should only take home library books they will read that night

You can’t make a call or send a text on your mobile phone in the US town of Green Bank, West Virginia. Wireless Internet is outlawed, as is Bluetooth. As you approach the tiny town on a two-lane road that snakes through the mountains, your mobile phone signal drops out, and your radio stops working. The rusted pay phone on the north side of town is the only way for a visitor to reach the rest of the world. It’s a pre-modern place by design, lacking of the latest technologies that define life today.

The reason for the town’s empty airwaves is apparent the moment you arrive. It’s the Robert C. Byrd telescope, also known as the GBT, a shiny white, 147-metre-tall satellite dish. It’s the largest of its kind in the world and one of nine in Green Bank, all of them government owned and operated by the National Radio Astronomy Observatory (NRAO).

You don’t look through these kinds of telescopes. They’re radio telescopes, so instead of looking for distant stars, they listen for them. There’s a long line of astronomers all over the world who want to use the telescope which is so sensitive that it could hear a single snowflake hitting the ground 1,000 miles away.

Such a sensitive listening tool needs total technological silence to operate, so in 1958 the US government created a National Radio Quiet Zone, a 33,000 km2 area covering Green Bank where, to this day, electronic and radio signals are forbidden every hour of every day.

People who live within a 15km of the Green Bank telescope are allowed to use landline telephones, wired Internet and cable televisions, but microwave ovens, wireless Internet and radios are forbidden. You can have a mobile phone, but you won’t get a signal.

Because of how much its way of life varies from the rest of America, Green Bank seems to be a somewhat isolated (隔绝), even alien place. For locals, the technology ban is annoying. For others who come to Green Bank for a little rest and relaxation, the town has become a refuge.

1.What do we know about the town of Green Bank from Paragraph 1?

A. It’s located at the base of a large mountain.

B. It is geographically and technologically isolated.

C. Its telecommunications are affected by its geography.

D. Many people live in the town and its surrounding areas.

2.How does the GBT work?

A. It traps light waves in its huge dish.

B. It stops all electronic and radio signals.

C. It receives pictures from space satellites.

D. It listens for and receives noises from space.

3.What equipment are locals of the Green Bank allowed to use?

A. Cable TV, wired Internet and radio.

B. Landline phones, wired Internet and cable TV.

C. Public phones, wireless Internet and mobile phones.

D. Landline phones, microwave ovens and cable internet.

4.What does the underlined word “refuge” in the last paragraph most probably mean?

A. A place of escape. B. A source of confusion.

C. An area of interest. D. A sign of danger.

Make the right choices

What is life’s greatest gift?1.Choice is the ability to select one course of action from a set of alternatives to achieve a goal. What is so great about choice? It transforms us from dumb animals into artists. Each of us becomes another Michelangelo. Choice becomes nothing other than the tool we use to sculpt (雕刻)our life. The tool doesn’t come free, however, for the price of choice is responsibility.2.The reward is happiness.

Life is not still. It is a flow.3.We constantly need to monitor where we are on our journey. We need to ask questions: Am I moving closer to my goals? If not, what corrective measures can I take? What action will I take now to readjust myself to my goals? Choice is power. Choice is at the heart of life. It is the creative power of life.

4.And your life becomes more convenient or comfortable because of them. For example, you decide which stores to shop at and which gas station to go to. But the decisions that we make to sculpt our lives are far more important than deciding where to shop. The more we appreciate the difference between minor and major decisions, the greater the probability that we will experience happiness and fulfillment.

Many freshmen may get anxious at the thought of living at their new campus and making friends but 18-year-old Melanie Salazar already has someone older and wiser to show her the ropes: her 82-year-old grandfather. The story of Salazar and her grandpa, Rene Neira, is spreading after she showed a photo of her grandpa’s first day of class this term at Palo Alto College (PAC).

I’m so proud of my grandpa for finishing his first day at PAC this term! He is 82 years old and not giving up,” said Salazar then. The old man is now in his second term at the community college with just one class left before he gains his associate’s degree(副学士学位) in economics. Salazar, meanwhile, has just started her studies there. “Grandpa and I are very close,” Salazar said. “I like to say he’s my best friend.” She said that it’s nice to have her grandpa on campus, whether they’re walking to class together or having lunch.

Neira first went to college in the 1950s, but after getting married and starting a family he had to put his dream of getting a degree on hold to raise his family. He took classes throughout the years, but it’s only now that he’s finally close to reaching his goal. With plans to graduate soon, Neira won’t just stop with his associate’s degree. He hopes to attend the University of Texas at San Antonio to get his bachelor’s degree.

Salazar’s sweet social media post is inspiring dozens across the Internet, young and old. “My grandpa is very hard-working,” she said. “He will spend hours in the library studying in his own time because he’s very devoted to his education. It’s amazing that his story can inspire so many people in this way.”
