By today's standards, my mobile phone is pretty rubbish. It's a Nokia 1616. If that doesn't mean much to you (it's not the kind of phone you see advertised on television), all you need to know is that it's a small, not very heavy device with which you can send and receive telephone calls and text messages. It also has a very handy torch on the top for when you can't find your keys, or when you drop something on the floor in the cinema. Other than that, my phone doesn't do much. Well, it has an alarm, and it probably has a calculator and things like that, but it's nothing compared to a smartphone. Why would I want one of those?

I have often been told that the big advantage of having a smartphone is that "you can do everything with them!" But when was the last time you saw someone doing "everything" with a smartphone? Okay, so they may have an endless list of functions, but generally they are used for checking social networking sites, playing games, and receiving and replying to emails. I'm happy just doing all of those things at home on my laptop.

As far as I can tell, the best thing about having a smartphone is that you can be connected to the Internet all the time. Don't get me wrong, I love the internet, but I just don't see the point of constantly being online. I can't remember the last time I received a Facebook update which was so very urgent that I had to read it as soon as it appeared, and I can't imagine ever having a job which was so important that I would need to read work-related emails immediately. I would think that if someone needed me urgently, they would just ring me rather than send an email. And my trusty Nokia can manage that.

One of the most peculiar(独特的)effects of the smartphone is, in my opinion, the newly-found addiction to maps and navigation (导航) systems. Is there anything more boring than knowing exactly where you are all of the time?! How do you get to know an area if you don't get lost there a few times? And if you are dependent on online maps, what happens to those great places you find just by chance? You can't exactly find out from Google maps the journey from "here" to" that hidden cafe with the tasty-looking cakes" , or to "that pond next to the church which looks really pretty in the evening sun. " It is, of course, true that we all occasionally need to be pointed in the right direction, but I find that there are often real life humans you can ask.

There are many benefits of having a very basic mobile phone, like the fact that it cost me about twenty pounds, and that I don't have to worry too much about it being stolen .But the main benefit has to be the fact that it provides me with the word 'greatest excuse for my bad habits’. Whether it's turning up late to events ,or getting lost on a trip, or missing buses or trains ,or forgetting about an appointment at work ,I'm pretty sure I'm covered with the following explanation: “I’m really sorry, I don't have a smartphone."

How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the US.

For some parents, the Internet can seem like a jungle (丛林), filled with danger for their children. But jungles contain wonders as well as dangers and with good guides, some education and a few precautions (预防), the wilds of the Internet can be safely navigated . "Kids have to be on-line. If we tell our kids they can’t be allowed to surf the Internet, we are cutting them from their future,” said an expert.

Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a “content screener ". But this can’t be wholly reliable, and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or to do on the Internet. Another way is that Mum or Dad is nearby when the child is surfing the Internet.

A few other tips:

--- Don't put the PC in the child's room but keep it in an area where Mum or Dad can keep an eye on things. That also makes the Internet more of a family activity.

--- Ask your child what he or she has been doing and about any friend they make online,

--- Tell your child not to give on-line strangers personal information, especially like address and phone number.

--- And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

1.What is the best way to protect children from improper materials?

A. To fix a content screener on the computer.

B. To be nearby when they are surfing the Internet.

C. To talk to them and persuade them to tell right from wrong.

D. To buy some search engines for children.

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

A. Surfing the Internet is the best way of educating children.

B. Using a content screener is most reliable for keeping children having ways to the Internet.

C. Search engines can help children to select materials fit for them.

D. Children’s not having chances to go to the Internet may have effect on their progress.

3.According to the passage, we can infer that _____.

A. softwares fit for children want programming.

B. the Internet will be protected by law

C. the Internet contains a lot of harmful sites

D. a child who is on-line is in danger

4.What does the passage tell us most?

A. Education. B. Precautions.

C. Search engines. D. Software.

Alaska’s Arctic lakes now freeze later and melt earlier in the year than in 1950,leaving them easy to suffer water loss from evaporation(蒸发)and possibly adding to local warming,a new study finds.The winter ice season near Barrow,Alaska,is shorter than in 1950,researchers reported Jan.30 in the journal The Cryosphere.

Lake ice is also thinner each winter.The scientists surveyed 402 lakes on the North Slope,where permafrost (permanently frozen ground)and shallow lakes dominate the areA. In 2011,the lake ice was 38 percent thinner than in 1950,and 22 percent fewer lakes froze through to their bottoms.

“When we saw the actual numbers we were shocked at how dramatic the change has been,”lead study author Cristina Surdu,of the University of Waterloo in Canada,said in a statement.Surdu and her co-authors analyzed the changes in lake—ice thickness and ice cover with satellite images and climate model simulations(satellite images are only available from 1991).

The climate models suggest the Arctic lakes froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared with the winter of 1950.“The changes in ice and the shortened winter affect Northern communities that depend on ice roads to transport goods,”Surdu saiD. For example,every winter,oil companies build roads over frozen lakes to carry supplies to Prudhoe Bay.

“The dramatic changes in lake ice may also contribute to further warming of the entire region,because open water on lakes contributes to warmer air temperatures,”Surdu saiD. The Arctic is warming twice as fast as the rest of the planet,for reasons that may include its layered atmosphere,which traps heat,and the loss of sea ice and snow cover,which help reflect the sun’s energy when present.

1.What does the text mainly tell us?

A. Arctic 1akes now freeze earlier and melt 1ater.

B. Alaska’s local warming is decreasing sharply.

C. Arctic lakes are losing ice.

D. Arctic lakes hold more flesh water than before.

2.According to the text,the great changes of Alaska’s Arctic lakes ________.

A. are totally beyond Surdu’s expectations

B. are completely within Surdu’s expectations

C. come as no surprise to Surdu and her co-authors

D. come as a great excitement to Surdu

3.How many days was the winter ice season of Arctic 1akes in 2011 shorter than that in 1950?

A. 6 days.

B. 12 days.

C. 18 days.

D. 24 days.

4.What is the last paragraph mainly about according to Surdu?

A. What reflects the sun’s energy.

B. How its layered atmosphere traps heat.

C. Why our planet is warming.

D. Why the Arctic region is becoming warmer.

Researchers in the US say they might have discovered how to fight against and even reverse some processes of ageing, at least in mice. Injecting the blood of young mice into the older ones improved their brainpower, a study found. Scientists at Stanford University plan to carry out trials in people in the hope that new treatments for dementia(痴呆症) can be developed.

“There are factors present in blood from young mice that can recharge an old mouse’s brain so that it functions more like a younger one,”says Dr. Tony from Stanford University School of medicine. In the study published in Nature Medicine, mice aged 18 months were given injections of the blood taken from mice aged 3 months. The injected mice performed better on memory tests than mice of the same age that had not been given the blood. Dr. Tony said it was not known whether the same was true of humans, but a trial was planned.

A research center in UK said the treatment restored certain aspects of learning and memory in mice, but was of unknown importance to humans. The research, while very interesting, did not test the type of brain damage that was seen in dementia, which is not a necessary consequence of ageing.

Meanwhile, two similar studies by a separate team have thrown more light on how young blood may benefit the old, in mice at least. A substance in the blood of mice previously shown to have an anti-ageing effect on heart muscle also improved brain cells, according to a Harvard team. The research, published in Science, found the blood factors encouraged the growth of brain cells in old mice, and restored their sense of smell. The same chemical also improved muscle power of aged mice, the researchers found.

1. The underlined word in paragraph 1 probably means _________.

A. change B. destroy

C. speed D. increase

2. Scientists in the US will test the discovery in humans with the aim of __________.

A. proving the possibility to live longer.

B. showing the importance of scientific research.

C. publishing the study in Nature Medicine.

D. treating an age-related disease successfully.

3.According to the studies, the blood from young mice benefits the old in certain ways except in_________.

A. memory B. muscle power

C. fur color D. brain cells

4.What’s the author’s attitude to the anti-ageing studies?

A. supportive B. objective

C. negative D. doubtful
