It was a triumph of hope and determination over property prices, and the peak of a 20-year dream. The day I got the keys should have been the most exciting day of my life and yet, the second I opened the door, panic set in. I spent my first night as a homeowner in a hotel researching how to sell a flat and wondering if it was too late to change my mind.I didn't sell my flat because I remembered why I had wanted it in the first place 一 but there are times when we get what we want and it simply isn't right. I've always found a strange disconnect between wanting something and getting it. Wanting is a place of possibility and, in a state of lack, the desire is strong. We imagine how this thing a new job or relationship - can change our lives and at the same time forget that adding something to our life doesn't mean all our problems disappear. We create a narrative around the desire and, when we get it, and it is different to how we pictured it, we feel frustrated.For me, this most often occurs in relationships. I have a habit of filling in the gaps with people, rather than getting to know them. 1 go on a date with someone and, instead of piecing them together brick by brick, I start to imagine what my life would be like with them in it. It shouldn't have been a shock that the reality in no way matched my fantasy - but it was. I knew I wanted out, yet part of me felt committed: this was someone I thought I had wanted for so long, I couldn't walk away, could I?We tend to shame others for changing their minds. I think, however, it's far braver to move towards something that will bring happiness than to stay in a miserable situation to protect your pride. So, when someone tells you they've changed their minds, congratulate them on knowing themselves well enough, and being strong enough, to admit it. It takes a lot to come clean about getting it wrong, but the relief of doing so of setting ourselves free from a personal-shaped hole, is worth it every time.5 .

An unexcepted accidentIn the history of medicine, the ability to clean surgical instruments, by exposing them to high-pressure steam in an autoclave （高压蒸气灭菌器），has been essential to the development of modern surgery. A mere 12 minutes in an autoclave at 121 and two atmospheres of pressure kills 99.99% of common bacteria.Electrically powered autoclaves have, as a consequence, become so routine as to be almost unnoticed at least in those places with a reliable electricity supply. Where electricity is not reliable, though, it can be hard to keep surgical instruments bacteria free. This is a problem to which Zhao Lin of the Massachusetts Institute of Technology thinks he may have an answer. As he and his colleagues describe in Joule, they have designed an autoclave that is powered directly by sunlight. And not only that - they also estimate it should cost just a tenth as much to make commercially as a common equal - quality autoclave.Dr Zhao's device is a work of simplicity and cheap materials. It consists of a metre-long box of rectangular base, with two curved fins （鳍状物）of polished metal sticking out of the top. Each fin forms a section of a parabola （抛物线），and it is a property of parabolic mirrors to focus light from distant sources （the sun, for example） onto a single point 一 or, in the case of long and thin mirrors like these, onto a line.The new invention's principal trick is that these focused lines coincide with the edges of a metal plate within the box. This plate is part of a commercially available device called a fin-tube absorber. The absorber's other element is a metal pipe running along the plate's central point. The particular fins mean that any incident sunlight will continue to be focused onto the metal plate even when the sun is not directly overhead. Anything inside the pipe is therefore going to get 一 and stay 一 pretty hot.In tests carried out at a hospital in Mumbai, in partnership with the Indian Institute of Technology in that city, Dr Zhao's new autoclave was able to sustain steam at a temperature of 128 and two atmospheres of pressure for half an hour. When tested, a material used routinely to make sure autoclaves are working properly, it passed with flying colours, meaning it would have successfully sterilized （7肖毒）anything within it.Demand for this product is likely to be high. Some 15% of hospital patients in low- and middle-income countries get infected. Dr Zhao therefore hopes to have commercial versions ready by 2022.8 . What did Dr Zhao expect to solve?1. Electrically powered autoclaves cannot work without electricity.8. The high temperature needed to kill bacteria is inaccessible.9. The previous autoclaves are too complex and expensive.10. It is hard to keep surgical instruments bacteria free.11. What can we know about Dr Zhao's autoclave?A.It iscomplex.B.It isportable.C.It isdelicate.D.It iseconomical.12. Which part of the device makes the incident sunlight continue to be focused?A.Thefins.B.Thepipe.C.Theplate.D.Thebase.13. What is most probably the next step of Dr Zhao's plan?A. To make the device to the market.B , To invent more to meet the demand.C. To put the device under observation.D. To send some devices to poor patients.Leg over leg, a furry brownish - black spider pulls on a single silk thread, tightening the frame of its web. It pulls and pulls and it waits. Minutes pass, sometimes hours. Then, when an unsuspecting insect flies by, the spider releases the thread, springing itself and its satellite-shaped web toward its prey. All of this happens in the blink of an eye.Those eye-watering numbers led Georgia Tech chemical engineer Saad Bhamla to wonder: How are these tiny spiders achieving such fast movements? Then he started to investigate. He checked the literature and found only a few papers. The papers were decades old and only described the slingshot motion, not the speeds or G-forces the spiders experienced. So Bhamla enlisted the help of his assistant, Symone Alexander, and together they "went out hunting fbr spiders in the Amazon rainforest,Alexander says.After locating one of the spiders, which measures roughly 2 millimeters in length, the researchers would set up portable high-speed cameras with special lenses and record its motions. Then, either Alexander or Bhamla would snap their fingers to get the spider to launch itself through the air. Only later did the pair learn that a human finger-snap closely matches the frequency of a buzzing mosquito and that seemed to be the only frequency that set the spiders* spring off. "It's just amazing that we can snap our fingers and get this magical thing J Bhamla says.Analyzing the footage, Alexander and Bhamla could watch exactly how the spider adjusted itself on the tension line at the front of its web. The speed and acceleration of this spider are impressive, but so is the fact that, unlike most web-building spiders, it's actively hunting, Bhamla says. “It's changed the function of its web, " he says. "Instead of waiting for something to bump into it, the spider is going after things actually catching flying insects in midair.14. What does the underlined word “prey'Tefer to?A. The web.B. The thread.C. The insect.D. The spider.15. What does the first paragraph mainly describe?A. How a tiny spider achieves such fast movements.B , How a tiny spider catches an unsuspecting insect.C. What a tiny spider does to tighten the frame of its web.D. Why a tiny spider uses the thread to launch itself to hunt.16. What did the researchers do to capture the motions of the spider?A. They checked quantities of literature before their hiking.B. They snapped their fingers acting as a buzzing mosquito.C. They set up portable high-speed cameras with normal lenses.D. They watched and analyzed the spidefs footprints on the web.17. Where is this text most likely from?A. A diary.B. A guidebook.C. A magazine.D.

His mother, Dr. Carolyn Barber, 21 in a busy emergency room and would come home with stories about the homeless 22 she had treated there.“We were trying to 23 if there was some kind of work program or something that we do for the homeless instead of just 24 them with medicines," Dr. Barber said.One night, Barber found a TED Talk 25 "A practical way to help the homeless find work and safety?9 The Talk 26 Barber's interest.

Workers said the money that they've earned has made a big 38.“It makes you feel like you're a 39 again/9 said Louis Varga, whoworks for Wheels of Change.
