In a computer age，a broadband Internet connection is very popular now．Whether cable or mobile broadband，today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly，and files download much faster than ten years ago．And the files are much bigger too．

There’s a hidden problem：You have to live near enough to a major city to get broadband Internet. If you don’t，it's slow dial-up access for you. And for those living really far out，there may be no Internet access at a11．

Technology experts often talk about the “l(fā)ast mile” problem， which refers to the difficulty of bringing Internet access to remote locations．In cities and suburbs(郊區(qū))，it's relatively easy to provide access for everyone．It is much more difficult to deliver access to those living far from cities，especially in developing countries．Internet service providers．for their part，have been reluctant to provide access to sparsely(稀疏地)populated areas．The handful of Internet users they would reach wouldn’t cover the expense.

But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere．

Some companies have delivered the Internet over standard power lines. Advancements in cheaper more efficient fiber optics cables(光纖電纜)promise to bring extremely fast Internet connections to more users．Still．the“l(fā)ast mile”problem remains hard to deal with．There will always be somewhere that doesn’t have an affordable broadband connection．But someday that might not matter．If the rapid progress in cell phone technology is any indication，it may not be too long before an Internet connection simply follows you wherever you go.

1. Which of the following is TRUE according to the passage?

A．Internet connections have been popular everywhere．

B．Internet service providers are willing to care about rural(農(nóng)村的)customers．

C. The problem of Internet access hasn’t been completely dealt with

D. Computer can’t become popular in developing countries．

2.Paragraph 4 mainly tells us that technological advancements_______.

A．make TV and telephone available everywhere

B．bring great change to people’s everyday life

C. bring faster Internet connections to users

D. make it possible for more people to use the Internet

3.What may eventually settle the“l(fā)ast mile”problem?

A. The broadband connection’s getting faster．

B．The rapid progress in cell phone technology．

C．More and more Internet connections．

D. More and more Internet users

4.The best title for this passage may be________．

A．Internet Connection Problems

B．Internet Connections Need Improving

C. Progress in Internet Connections

D．Internet Connections Today

You may have seen a talking parrot on a TV show, in a movie, or even in someone’s home. The parrot has learned to copy sounds that people make. Birds are not the only animals that can copy the noises they hear. Dolphins, bats, and some apes also copy sounds. Now we can add elephants to this list of copycats.

Dr. Joyce Poole is a zoologist. She studies the sounds of elephants. While she was in Kenya, she would hear strange noises made by Mlaika after sunset. Mlaika was a 10-year-old African elephant.

Mlaika lived near a highway. Dr. Poole says, “I could not tell the difference between Mlaika’s call and the distant truck noise.” She and other scientists studied Mlaika’s sounds. It turned out that Mlaika was copying the sounds of the trucks driving by. Why would Mlaika copy trucks that she heard going by on the highway? Animals that are able to copy sounds may enjoy practicing new sounds. When they are kept outside of their natural environment, they may copy unusual sounds. That may be why an elephant would copy the sound of a truck.

“Mlaika was not the only copycat elephant,” Dr. Poole says. Calimero is a 23-year-old male African elephant. He spent 18 years with two female Asian elephants. Asian elephants make chirping sounds (sounds made by birds) to talk with one another. African elephants usually do not make chirping sounds. But Calimero now does. He is copying his Asian elephant friends. Dr. Poole says that elephants need to form bonds with their family and friends. She says, “They make sounds to communicate with each other. When they are separated, they use sounds to keep in contact.”

Parrots, dolphins, humans, and elephants show that being a copycat is one way that animals and people make new friends and keep old ones.

1.According to the passage, what does Mlaika copy?

A. The sound of people. B. The sound of trucks.

C. The sound of Calimero. D. The sound of birds.

2.Why is Calimero mentioned in the passage?

A. To clarify the meaning of copycat elephants.

B. To show the cleverness of African elephants.

C. To add another example of copycat elephants.

D. To introduce a special life skill of Asian elephants.

3.From paragraph 4, we can know ________.

A. how long it takes for an elephant to learn a new sound

B. why the African elephant can make chirping sounds

C. why the Asian elephants make noises after sunset

D. how Asian and African elephants are alike

4.According to the passage, why do some animals like to be copycats?

A. To keep in touch with nature.

B. To please people and other animals.

C. To make new friends and keep old ones.

D. To avoid the danger from the outside world.

Reducing the amount of salt in our diets could save nearly 20,000 lives in the UK every year, according to researchers.

The recommended maximum daily intake for adults is 6g in the UK, although just month the World Health Organization (WHO) revised this down to 5g. Yet according to figures from the British Heat Foundation, men consume around 9.7g a day, while women have 7.7 g.

Fast food

Salt Content

Original chicken

2.9g per portion (份)

Spicy crayfish

3.5g per portion

Large chips

1 per portion

McDonald’s Big Mac

2.1 per portion

Not researchers at three universities, including Harvard Medical School, have revealed the dramatic effect reducing salt could have on death rates by using computer models. They estimated that reducing salt intake to 6g would save 500,000 to 850,000 lives in the US over the next decade.

British doctor Ian Campbell, medical director of charity Weight Concern, told Mail Online: Salt is a big problem in the UK, too. It’s a silent killer. Over time consuming too much of it increases the risk of high blood pressure, which can lead to heart attacks. About 80 percent of our salt intake comes from processed foods, so it can be difficult to avoid.

Many people are unaware of where salt is hidden, such as bread, soups, ready meals, and even breakfast cereals (麥片). The government approach has been to encourage food companies to cut the amount of salt in their products. There has been a reduction but it is taking too long. The Food Standards Agency should consider setting compulsory maximum levels for salt.

Victoria Taylor, Senior Dietitian at the British Heat Foundation, added: Eating too much salt may raise your blood pressure and having high blood pressure increases your risk of developing heart disease.

The government has worked with the food industry to reduce the amount of salt in our food and make labels clearer. But there is still work to be down by everyone because the majority of Brits are still consuming more salt than they would be.

1.Which of the following in the table reaches the daily maximum amount of salt recommended by the WHO?

A. A large chips and a McDonald’s Big Mac.

B. A spicy crayfish and a large chips.

C. An original chicken and a spicy crayfish.

D. A McDonald’s Big Mac and an original chicken.

2.According to the passage, when people eat processed food they ________.

A. needn’t add salt

B. should add a little salt

C. may ruin their health

D. can have risk of heart attacks

3.To solve the problem of eating too much salt, Ian Campbell advises ________.

A. having healthier breakfast

B. punishing the illegal food companies

C. reducing the amount of processed food

D. making laws about maximum levels for salt

4.The last paragraph emphasizes the importance of ________.

A. making food tables clearer

B. monitoring the food industry

C. promoting the awareness of salt content

D. strengthening the government’s functions
