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

“Is there anything else you need, honey?” my dad asked me as he put three twenty dollar bills in my hand. I was traveling back home from a family visit, and after treating me to breakfast and filling my car with gas, it was obvious that my dad wanted to make sure that I would be okay on the road.
“No, Dad. You've done so much already. Thank you！” I was overwhelmed once again by his kind acts of providing everything I needed, although I turned 40. Yet I realize that in my father's eyes, I will always be his little girl. He takes deep pleasure in knowing his children are all right. Now that he has enough money, he loves to give whenever he sees a need.
But this was not always the case. Divorced from my mother when I was 11, my dad couldn't be around his kids as often as he would have liked. Money was also tight; even weekend visits were rare. However, my dad stayed in constant communication with us and made sure he was involved in our lives. Though he couldn't always be there in person, I knew he was only a phone call away. I could always make sure of that.
Even now, almost 30 years later, I treasure knowing that I can pick up the phone and call Dad, and he'll be there for me. I have a wonderful husband, but that hasn't changed how Dad sees me. I'm still his child and he loves to see that my needs are met.
I remember a time when I was shopping in a hardware store (五金店) with Dad. I mentioned my plans to paint one wall in my house. Well, that's all it took for Dad to take action. By the time I got to the checkout(结账) line, all the supplies I picked out were put out of my hands and placed with things he bought.
Then there was the time when I took him with me to do some grocery shopping for just a few “ items”. By the time we were finished, my shopping cart was full of groceries from every shelf in the store! My sister and I joke that if you don't want Dad to buy it for you, avoid even mentioning you want something.

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."
1.The writer uses his Nokia 1616 mainly to _______.
A. play online games
B. do calculating work
C. check social network sites
D. make calls and text messages
2.It can be inferred from the above passage that_______.
A. work-related emails should be answered immediately
B. a laptop and a smartphone share many functions
C. smartphones should always be connected to the net
D. a Facebook update is usually very important
3.According to the passage, if you use navigation systems, you may _____
A. miss some really wonderful places
B. find a boring trip actually exciting
C. be persuaded to eat in a certain café
D. be misled to a totally wrong place
4.The writer’s purpose for writing this article is to______
A. explain why he doesn’t want a smartphone
B. warn readers of the risks of using smartphones
C. complain about the troubles caused by smartphones
D. inform readers of the latest development of mobile phones

What is the hottest topic at your school recently? In Taiyuan No. 55 Middle School, it’s money.
The school held an activity called “making money” last weekend. About 200 Junior 1 and Junior 2 students were divided into 30 teams. They went out to make money by selling things.
What did they choose to sell? Some sold newspapers; some chose bottled water; some sold environmentally friendly shopping bags and bamboo baskets.
Hu Qing’s team decided to sell some useful books in front of the Children Activity Center. They thought parents would like to buy the books for their children. But unfortunately, they met urban management officers (城管). The officers asked them to leave. “We played hide-and-seek (捉迷藏) with the officers for the whole morning” said Hu. “Finally we had to give up.”
Wang Bing and her team sold ice cream in a square. They didn’t meet any officers. But few people were interested in what they were selling. The team then put up a board saying “For Country Kids”. It worked. More people came to their stall (小摊). A foreigner even gave them 100 yuan. “He didn’t want any change. He said he wanted to help the children,” said Wang. “We were touched.” Later that day they gave the 100 yuan and more to the “Project Hope” office.
Meng Zhaoxiang and his team were luckier. They sold all their cakes in four hours, spending 39.5 yuan and getting back 80 yuan. They made 40.5 yuan. “It was not easy to make the money,” said Meng. “Some people just looked. Others just tasted but didn’t buy. Now I know how hard it is for our parents to make the money we need to lead happy lives.”
