Have you ever imagined what human beings will look like in the future? Well, now you don't have to. According to AsapScience, a Canada-based video channel that touches on many different science topics, humans will be very different creatures 1,000 years from now. Artificial intelligence, genetic engineering and climate change will work together to change our bodies greatly, according to a video recently published by the channel. We could, for instance, develop red eyes as our DNA changes, and have darker skin because of global warming. The video painted a picture of a future world in which our bodies are part human, part machine. Nanobots, or tiny robots, will be put into our bodies, improving our abilities. "No longer will we be limited by our own physiology. We will truly become a mixture of biology and machine on the inside," says the video. Meanwhile, designer babies will cause future generations to grow into intelligent, attractive people. As global warming takes hold, humans will also be skinnier and taller, as this body shape deals with heat better. In fact, Cadell Last, a researcher at the Global Brain Institute located in Belgium, believes change may happen even faster than this. As he said in a paper recently published in Current Aging Science, mankind is already going through a major evolutionary change. In less than four decades, Last claims, we will live longer, have children in old age and need artificial intelligence to finish daily tasks. "Your 80 or 100 is going to be so radically different than your grandparents," Last said. Instead of living fast and dying young, he believes humans will live slow and die old. "The biological clock isn't going to be around forever," he added, and said that people could pause it for some time using future technology. Just a few hundred years ago, most humans were working in the fields, while nowadays more and more are getting an education. These are just predictions, and no one can be sure how human beings will evolve in the future. But with such large... The video released by AsapScience said that _ . A) humans will be thinner and shorter B) future humans' bodies will be part machine C) humans will develop red eyes that will enable them to see clearly at night D) tiny robots will be put in humans' minds and will give them super abilities

Commencement is a time for idealism. But economic reality is cruel everywhere; especially for new college graduates. They have been told repeatedly that a college degree is an open sesame to the global economy, But that's not necessarily so, according to new research by two economists at the Massachusetts Institute of Technology, Frank Levy and Peter Temin. It is true that people with college degrees make more money than people without degrees. The gap has narrowed somewhat in recent years, which is disturbing. But the earning power of college graduates still far outpaces that of less-educated workers. The bad news, though, is that a college degree does not ensure a bigger share of the economic pie for many graduates. In recent decades Mr. Levy and Mr. Temin show, only. college-educated women have seen their income grow in line with economy wide gains in productivity . The earnings of male college graduates have failed to keep pace with productivity gains. Instead, a huge share of productivity growth, which expands the nation's total income, is going to Americans on the top of the income scale. In 2005, the latest year with available data, the top 1 percent of Americans--whose average annual income was $1.1 million-- took in 21.8 percent of the nation's income, their largest share since I929. Administration officials, and other politicians and economists, often, believe that income inequality, reflects an education gap. But Mr. Levy and Mr. Temin show that in the case of men, the average bachelor's degree is not enough to catch the rising tide of the global economy. They argue that the real reason that inequality is worsening is the lack of strong policies that broadly distribute economic gains. In the past, for example, a more progressive income tax and unions promote equality. Positive measures have also helped and probably accounts, in part, for the pay growth of college-educated women. But such measures have been eroding and new ones have not yet emerged, making the income gap even greater. Mr.... From the passage, some economists believe that the worsening income inequality is caused by _ . A) lower college degree of college graduates B) lack of proper governmental policies C) gender discrimination D) underdevelopment of economy and productivity

Ques: Einstein was born in 1879 in Germany. As a child, he was slow to learn to talk. As a pupil, he was backward. But when he was fourteen years old, he became clever. He taught himself maths from textbooks. He studied hard because he wanted to be a physicist. In 1901, Einstein began teaching. In 1902 he continued his studies at the University of Zurich. Several years later, he formulated his famous Theory of Relativity .To most people the law of relativity is difficult to explain. But once Einstein explained it very well to a group of young students. He said, "When you sit with a good girl for two hours, you think it is only a minute. But when you sit on a hot stove for a minute, you think it's two hours. That is relativity." After Hitler came into power in Germany, Einstein went to America. In 1940 Einstein became an American citizen. In 1955, Einstein's life ended at the age of seventy-six. Which of the following do you think is true? A) The Germans owed their scientific progress to Einstein. B) Einstein made a very great contribution to modern science. C) Einstein owed a great deal to the modern world. D) The Americans owed all their economic development to Einstein.
Ans: B
Ques: Many people know the names Alexander Graham Bell and Thomas Edison. However, most people don't know the name of the man who invented the television, Philo Farnsworth. Philo Farnsworth was born in 1906 and grew up on a potato farm. As a boy, he loved to learn about science, and he read a lot of science books. When he was only thirteen years old, he drew a picture of a machine that could send pictures as radio sends sounds. He got the idea from the way the potatoes were planted in the field. The potatoes grew in long lines, side by side. This made a shape in Philo's mind. This shape helped Philo think of a way to send the TV picture onto a piece of glass. But he was poor, so Philo could not try to make his idea into a machine at that time. Later, Philo worked at many different jobs. He worked with trees. He worked on broken radios. He worked on trains. He also worked as a street cleaner. At last, two rich men heard about his idea for television, and they gave him the money to make it. On September 7th, 1927, they watched Philo test the machine he built. When Philo turned on the machine, a small line could be seen on the glass. Philo said, "There you have it, electric television." Later, a big company, RCA, said they had made the first television. Philo had to spend a lot of money on lawyers to fight them. Finally, he won. Then, World War Two started in 1939. During the war, Philo spent a lot of money helping the US army instead of _ his television company. After the war, other bigger, richer companies started making televisions. In the end, Philo had to sell his company. Philo Farnsworth got the idea for TV from _ . A) the radio B) science books C) potato fields D) a machine
