Think positive
How are you feeling today? If your head 's in a spin because you 've had a bad night 's sleep, or maybe you've just got too much to do, the chances are you 're not in the best of moods. If everything seems like an effort and you have a negative attitude, the last thing you want to be told is to ‘be positive ! 1. .
Of course, developing a positive attitude is easier said than done. 2. When you're
feeling down, it is hard to be optimistic. But a study in the US has found that people who are optimists are more likely to live longer than those who have a more negative approach to life. So, maybe the thought of a longer life might encourage you to have a more hopeful outlook on life.
3. . Professor Lewina Lee from Boston University School of Medicine, who worked on the study, told the BBC that : “Our findings speak to the possibility that raising levels of optimism may promote longevity and healthy ageing. ” And she advises that pessimists could benefit from doing things like imagining a future where everything turns out well.
4. .Vicki Siska says “Music feeds my soul. A sense of humour keeps things in perspective.” And Pippa Kennedy says “ being grateful for what you have — and lots of chocolate —helps ! ” 5. . That's probably why other people have recommended doing yoga as well as staying fit and healthy to help maintain a positive outlook on life.
A. It doesn't come naturally to everyone.
B. As we know, every coin has two sides.
C. But being positive could have more benefits than you think.
D. Pessimists tend to give up when facing difficulties.
E. The saying goes that a healthy body leads a healthy mind.
F. People have been giving their personal advice on keeping a positive approach to life.
G. The study concluded that optimists may find it easier to control emotions and get less stressed.
Engineers in Upstate New York have invented a folded paper device that looks like a decorated art project. But don't be fooled. This is actually a paper-based battery. No, it doesn't look like any of those metal batteries running flashlights or smartphones. In these systems, the battery can be printed on a page. The battery 's power consists of living bacteria.
Paper electronics are simple to make and inexpensive, notes study leader Seokheun Choi, an engineer at Binghamton University. They need no electrical outlet to recharge. They just need more bacteria, which can be found everywhere — including dirty water.
“ Most batteries use chemicals to generate electricity. Substituting bacteria can be an advantage,” Choi says.“They are cheap and self-repairing.” What paper-based batteries won't do is generate much power. They do, however create enough to run small devices in faraway or dangerous places — such as a battlefield . They might also find use in medicine . For instance, they might power tiny sensors, such as the types used to measure blood sugar.
This invention is based on an observation made more than a century ago — that microbes （微生 物） produce electricity as they digest food. Scientists refer to the bio-batteries based on this principle as microbial fuel cells. A fuel cell generates electricity like a regular battery. But a regular battery stops producing electricity when its inner chemical reactions stop. A fuel cell uses fuel that can be refilled. In this case, bacteria serve as the fuel. By refilling more microbes, as needed, scientists can keep these fuel cells running.
Lab tests have shown that the new battery can produce a current. Now, Choi and his team are looking at ways to increase the power. They're studying different shapes and materials for the anode and cathode （正负 极）. They're also looking for the best ways to combine batteries for more power. The beauty of the paper devices is that you can simply fold them to connect them. And they surely will be a trend in the near future.

It seems every major city and town around the world hosts an annual marathon, with thousands of athletes running a gruelling 42.1 kilometres. While many runners' motivation is to beat their personal best and cross the finishing line without collapsing, they're also doing it for a good cause—to generate funds for charity. But like other major events, the marathon also generates a massive carbon footprint. Thousands travel —some by plane—to the location, and waste from food packaging and goody bags gets left behind by spectators and runners. This is becoming a big issue for cities—how to host a worthwhile event, encouraging people to exercise and help charities, while protecting the environment? Several cities have developed formal plans to reduce their environmental impact and promote sustainable （可持续的） ideas. One event in Wales, for example, introduced recycling for old running kit .
It's something that this year's London Marathon tried to tackle by reducing the number of drink stations on the running route, giving out water in paper cups and offering some drinks in eatable seaweed capsules. They also trialled new bottle belts made from recycled plastic so 700 runners could carry water bottles with them during their run. London Marathon event director Hugh Brasner told the BBC: “There are a lot of initiatives （倡议） we are using this year that we think will lead to some huge behavioural changes in the future.”
Meanwhile, some people still think running a marathon could be our best foot forward in helping the planet. Dr Andrea Collins from Cardiff University told the BBC: “Training for a marathon makes you more sustainable in day-to-day activities. I started walking or running to work every day and shunning public transport altogether. Being environmentally friendly while training sticks with you and becomes a way of life. ”
1.Why do many people enter for a marathon?
A.To achieve their own ambitions.
B.To generate a massive carbon footprint.

D.To challenge their personal limitations and raise money for charities.
2.What did Hugh Brasner think of this year's London Marathon?
A.It may bring a large profit to London.
B.It saved a lot of water resources and power.
C.It may improve people's behaviour in the future.
D.It may make Londoners more friendly when running a marathon.
3.Which of the following can replace the underlined word “shunning” in the last paragraph?
A.Damaging. B.Avoiding.
C.Choosing. D.Changing.
4.What can we infer from the last paragraph?
A.Running a marathon can make more money.

C.Running a marathon can change people's life completely.
D.Running a marathon can contribute to protecting the earth.
As the President of Ariel Investments, I am often asked how to cultivate （培 养） green hands to be qualified for a new job within a short time. My memories take me straight back to the days when I worked for John W. Rogers.
While in college, I worked as an intern （实 习生） at Ariel Investments. As the youngest girl of six kids from a single mom, I had very little knowledge of the business world. When I graduated, I decided to return to the company to improve myself.
At the age of 22, my perspective was greatly influenced by lunching with the company's founder and then-president, John W. Rogers. He told me that I would often find myself in the company of rich and successful people with big titles, lots of degrees and lots of experience. And yet, my ideas could still be as good or even better, he said. This early advice became the guiding force that has helped me throughout my entire career. When I was starting out, I thought my inexperience was holding me back, but John said that it was a good thing. He told me that being inexperienced means that you have a fresh point of view.
As my tutor, John encouraged me to be brave. As my boss, he took some giant leaps of faith to support me. Because of our first lunch and the years of support that followed, I never thought twice about speaking up, raising my hand or taking a seat at the table. Staying in the background was never a choice. But John 's advice came with one important warning. I needed to keep my attitude in check. It's one thing to be firm but quite another to be rude. Similarly, there is a fine line between confidence and overconfidence. With that in mind, I have had to learn to balance the way I act around others. As someone once told me, “the goal is to be non-threatened and non-threatening at the same time. ”
