Thousands of hungry birds left the countryside of Britain in the bitter winter to find food and warmth in urban gardens. The move included species such as the redwing and the fieldfare, almost unknown outside rural areas The hard situation of farmland birds has been revealed in the latest survey of bird populations from the Royal Society for the Protection of Birds released today. The redwing has an obvious stripe over the eye and a red flash on the flanks , while the fieldfare has a grey head, a peach underbelly, and a distinctive dark band on the tail. Graham Madge, the society's spokesman, says, "For many urban birdwatchers the sight of these striking species is a real treat. Many people have never imagined there being such an amazing chance." "Frozen ground prevented them from getting food in the countryside and they have been saved from starvation in towns," he added. He says the unusual sight this year somewhat _ the frustration felt at the suffering of small garden birds such as robins and wrens. These birds are sensitive to cold and must eat almost continuously to stay alive. Data from people who took part in the society's Big Garden Birdwatch recorded sightings in 280,000 gardens during the last weekend of January, with the goldcrest down 75 percent, the longtailed tit down 27 percent, and the coal tit down 20 percent. The study highlighted the need for food to be left out for birds during winter. The redwing and the fieldfare are relatively unknown outside the eastern part of the country. The research shows, however, that they moved to the other side of the country where the climate is generally mild in winter and that many for the first time have reached Cornwall and Isles of Scilly. The number of redwing sightings was up 185 percent, those of the fieldfare 73, and of the yellowhammer 68. Another surprise garden "guest" this year was the blackcap. This robinsized, silvergrey bird was rare in Britain 50 years ago, but increasing numbers now arrive each year from Germany and Austria. How did the urban birdwatchers probably feel when seeing the hungry birds? A) Excited. B) Worried. C) Annoyed. D) Motivated.

Ques: Look at the keyboard of any standard typewriter or computer."Q,""W,""E,""R""T"and"Y"are the first six letters.Who decided on this arrangement of the letters? And why? People tried for centuries to invent the typewriter.In 1714 in England,Henry Mill filed a patent for a machine called An Artificial Machine Or Method for the Impressing or Transcribing of Letters,Singly or Progressively one after another, as in Writing,whereby all Writing whatsoever may be Engrossed in Paper or Parchment so Neat and Exact as not to be distinguished from Print.That machine probably didn't sell because no one could remember its name! The first practical typewriter was patented in the United States in 1868 by Christopher Latham Sholes.His machine was known as the type-writer.It had a movable carriage,a lever for turning paper from line to line,and a keyboard on which the letters were arranged in alphabetical order. But Sholes had a problem.On his first model,his"ABC"key arrangement caused the keys to jam when the typist worked quickly.Sholes didn't know how to keep the keys from sticking,so his solution was to keep the typist from typing too fast.Sholes asked his brother-in-1aw to rearrange the keyboard so that the commonest letters were not so close together and the type bars would come from opposite directions.Thus they would not clash together and jam the machine.The new arrangement was the QWERTY arrangement typists use today.Of course,Sholes claimed that the new arrangement was scientific and would add speed and efficiency.The only efficiency it added was to slow the typist down,since almost any word in the English language required the typist's fingers to cover more distance on the keyboard. The advantages of the typewriter outweighed the disadvantages of the keyboard.Typists memorized the crazy letter arrangement,and the typewriter became a huge success.By the time typists had memorized the new arrangement of letters and built their speed,typewriter technology had improved,and the keys didn't stick as badly as they had at first. Sholes decided the QWERT arrangement of the keyboard in order to _ . A) arrange the letters in alphabetical order B) cause the keys to jam when the typist worked quickly C) solve the problem of the keys jamming D) compete with"ABC"key arrangement
Ans: C
Question: Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world. So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls ? Why don't we use them for collecting energy? The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work? The Solar Road Panels will contain embedded LEDs which "paint" the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour ahead. The road will be able to sense wildlife on the road and can warn drivers to "slow down". There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving. Replacing asphalt roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips. We just can't wait to see more of these roads all over the world in the near future. What is the text mainly about? A) Functions of the road in the future. B) Development of solar energy. C) Free energy on the road. D) Solar road of the future.
