It’s hard not to feel cheated and over-charged when you receive unexpected roaming (漫游) charges while traveling abroad—whether they come from making phone calls or checking e-mails.

Jeff Gardner received an $ 11,000 bill from Verizon after spending four days in Jamaica. Before the trip, Mr. Gardner, who runs a fly-fishing business in Grayling, Michigan, said he called Verizon to find out what it would cost to use his cellphone for calls and his wireless card to check e-mails while in Jamaica. He said he was told that calls would be about $ 2 a minute and that there would be no extra charges for data as he was on an unlimited plan. The latter part turned out to be wrong.

“I don’t mind paying a fair amount for fair service, but $11,000 for four days is ridiculous,” said Mr. Gardner, who used his phone carefully and economically on the trip. He also tried to check and send e-mails using his wireless card, but quickly gave up after the e-mails didn’t go through. Still, his Verizon bill said more than 500,000 kilobytes (千字节) of data was delivered while he was in Jamaica, an amount Mr. Gardner said is 100 times what he normally uses in a month.

As travelers increasingly use smart phones abroad in the same way they do at home—to check e-mails, update Facebook and Twitter and pull up online maps—many are facing costly roaming fees, which providers charge when customers use their phones outside their service area. In fact, roaming charges have gotten so out of hand that the Federal Communications Commission has proposed a plan that would require wireless companies to send their customers a voice or text message when they are approaching their plan’s limit, when they have reached that limit and when they are starting to result in roaming fees.

3.During the trip, Jeff Gardner______.

A. was careless with phone use

B. delivered no more data than at home

C. received quite poor e-mail services

D. frequently used his wireless card to send e-mails

4.What should wireless companies do according to the Federal Communications Commission?

A. Make customers know when they’re outside their service area.

B. Get customers informed when they’re near the limit of their plan.

C. Stop serving customers when they’ve reached their plan’s limit.

D. Limit some services to reduce the amount of roaming charges abroad.

We redheads are well known for our bad tempers. Now it seems there is scientific backing for our particular complaining as well.

Scientists in the United States studied a group of 144 dental patients almost half of whom had red hair. They found that the red-haired group were more sensitive to pain and as a result were twice as likely to avoid visiting the dentist.

Previous research had shown that redheads were more resistant to the effects of local anaesthesia(局部麻醉) than people with other hair colours.

The scientists say that this red-haired sensitivity to pain stems from the actions of a gene called MC1R. This is responsible for the production of melanin which gives skin and hair its colour. In about five percent of white people the gene is mutated(突变) leading to fair skin and red hair.

Researchers say there are some people with the gene in the brain and that this could affect pain sensitivity.

Professor Daniel Sessler from the Cleveland Clinic in the United States is one of the authors of the study. He says the research is a considerable scientific breakthrough.

"Red hair is the first phenotype(表现某一显性特征之生物个体或群体) of anaesthetic requirement in humans. And what I mean by phenotype is an external(外部的) characteristiC．

"So suppuse you are walking down the street and you see someone who's a little older and a little younger - that tells you nothing about their anaesthetic requirement. You see a man and a woman - that tells you nothing about their anaesthetic requirement. But you see a redhead - aha! You know that person is going to require 20 percent more general anaesthesia."

From my own personal experience I would say that there is some merit to this ideA．I have found that I have had to ask dentists for extra anaesthetic in the middle of procedures.

Some dentists argue that a greater sensitivity to pain might actually benefit redheads and drive them to see the dentist more quickly. In my own case I can prove that is definitely not true.

We learn from the text that red- haired group are _______________.

A．easily influenced by the sense of pain and need more anthaethetic reqiurement

B．usually more sensitive to some painful things

C．just well-known for their good temper and strong pain sensitivity

D．good-looking with fair skin and red hair

What do the scientists think this red-haired sensitivity to pain results from?

A．melanin which is responsible for the production which gives skin and hair its colour.

B．the mutated gene leading to fair skin and red hair基因

C．some persons with this gene in the brain

D．an external characteristic of a person.

According to Professor Daniel Sessler, the most amazing thing about the anaesthetic requirement in humans which can be judged by ______.

A．someone’s age and hair  

B．someome’s gender and figure

C．someone’s teeth and the skills of the dentist

D．someone’s external charateristic

We can infer from the last two paragraphs that _____.

A．redheads need less anaesthetic in the operation

B．the results of this red-haired sensitivity to pain will be the same

C．the writer is a red-haired person

D．redheads have many benefits of being red-haired

Besides containing attractive flowers, trees and other plants that beautify the community, eco-friendly rain gardens are healthy for the environment and the people living and working nearby.

A rain garden is not very different from a traditional garden. It is just a far more eco-friendly garden. Usually it is built lower than the ground. Rain gardens make smart use of rain and storm water by temporarily holding water from rain and storms and letting it soak slowly into the ground before it runs into streams or enters the public drinking water supply.

Thus, a rain garden keeps the water, allowing it to be used as needed by plants in the rain garden, rather than flowing immediately into nearby streams and going unused. The water will soak slowly into the ground within a day or two. This creates an advantage that the rain garden does not allow mosquitoes to breed. This is a simple, attractive, and eco-friendly “green” way to treat storm water.

What’s more, planting a rain garden helps reduce pollution and improve the environment. Without using expensive machinery and chemicals, rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%.

Native plants are recommended for rain gardens because they are more used to the local climate, soil, and water conditions. They may attract local wildlife such as native birds. Water your rain garden immediately after planting and once a week, unless you have had at least an inch of rain during the week. Once the native plants establish the necessary root system, it will require little care.

Often, local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems. However, you don’t need to be a professional environmental engineer to create a rain garden. As long as you’re eco-conscious homeowners, you can help the environment by building smaller rain gardens in your yards.

1.Which of the following is the eco-friendly function of rain gardens discussed in Paragraph 4?

A. They can keep the rain and storm water.

B. They can help reduce the pollution problem.

C. They can be healthy for the people around.

D. They can make the environment more beautiful.

2.One of the main reasons why native plants are recommended is that ______.

A. they cost less and are much easier to get

B. they may attract local wildlife to come

C. they require little care from the local gardeners

D. they are more used to the local growing conditions.

3.We can infer from the passage that after native plants are planted, rain gardens ______.

A. need little water             

B. need little care

C. need to be watered every day

D. needn’t be watered if there is at least an inch of rainwater per week
