Marie Curie had a great impact on the modern world. She was the first 【小题1】doctor of science in Europe, and the first woman to win a Nobel Prize. Her discovery of radioactive elements has helped to save or 【小题2】the lives of millions of people suffering from cancer. It has increased the production of power too. However, radioactivity can be very harmful to humans. Her discovery has also led to the invention of the nuclear bomb, and has caused some terrible accidents.

Marie Curie is most famous for her discovery of radium. But her biggest contribution to scientific research was her 【小题3】that radiation took place within the atom. Nuclear physics developed from this principle. However, nuclear physics can cause terrible 【小题4】and destruction. During the 1940s, scientists realized that if they 【小题5】an atom, they could release a huge amount of energy. It was this discovery that led to the production of atomic bombs. Atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki at the end of World War II. They caused terrible destruction, killed thousands of people and made lots of people very ill.

Another invention that followed from Marie Curic’s discoveries is the nuclear reactor. This generates electricity for homes and businesses. The earth does not have enough power to last forever. We only have limited supplies of coal and oil. Nuclear power 【小题6】will still be able to produce electricity after oil and coal have become scarce. It is much cleaner for the environment too. However, nuclear accidents may and 【小题7】happen. In Chernobyl in the Ukraine, there was an accident in a nuclear reactor in 1986. People in this area and for thousands of kilometers around the area suffered radiation 【小题8】. People are still suffering from the effects of radiation on their bodies today.

Marie Curie 【小题9】her life to science in the hope that it would improve people’s lives. We must make sure that we can all benefit from her work and example. Some people are 【小题10】that there exist the disadvantages of nuclear energy. However, we should remember that from the moment we get up in the morning until we go to sleep at night, we benefit from the discovery of nuclear power Agriculture, medicine, industry and research use radioactivity every day to produce and improve their products.

A small robot may help children who are recovering from a long-term illness in the hospital or at home.

These children may feel【小题1】from their friends and classmates. The robot takes their place   at school. Through the robot, the children can hear their teachers and friends.

Norwegian researchers have【小题2】a clever way to keep children recovering from long-term illness connected to their friends and their education. Now, these children may have a high-tech friend.-a robot.

The robot is called AV1. AV1 goes to school for a child who is【小题3】while recovering from a long-term illness. And the child’s school friends must help. They carry the robot between classes and place the robot on the child’s desk.

A Norwegian company called No Isolation created the robot. Karen Dolva was one of the co-founders. She explains how the robot AV1 works. From home, the child uses a tablet’ or phone to start the robot. Then they use the same device to control the robot’s【小题4】. At school, the robot becomes the eyes, ears and voice of the child.

The student can take part in classroom【小题5】from wherever they are recovering, whether at home or from a hospital bed. The robot is【小题6】with speakers, microphones and cameras that make communicating easy.

The robot was designed to be 【小题7】. It is water resistant and can take a fall from a desk without damage. Inside AV1, there is a small computer connected to a 4G network A small camera【小题8】up to a small computer could do the job. But that would not be the same.

AV1 is large and looks like a human for a reason. Dolva says this is important because the robot is【小题9】to be a friend to the children. And robots are, quite simply, cool. The robot just became【小题10】to the public. Hopefully AV1 will help some children feel less lonely while they are absent from class.

Tablets are really useful devices, but their big screens always make them a burden to carry around without a bag. Wouldn’t it be great if there were a phone with the powers of a tablet that could be folded up and fit 【小题1】 into the hand?

Now something like a tablet-shaped but fold-able phone is about to become 【小题2】. In February, South Korean electronics company Samsung and China’s Huawei both unveiled fold-able phones Galaxy Fold and Huawei Mate X 【小题3】. Mobile phone use has entered the “fold-able future”, The Verge noted.

The technology could change our lives in significant ways. These devices, due to their 【小题4】 screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they’re “the 【小题5】 of a small tablets and smart-phone, all in a single device”.

The technology could 【小题6】 other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modern cities, they will help us to 【小题7】 available space.

In a keynote address, Samsung’s senior vice president of mobile product marketing, Justin Denison, called the fold-able screen “the 【小题8】 for the smart-phone of tomorrow.” “It’s a balank canvas for us to do something beautiful together,” he said.

So is there nothing to stand in the way of the fold-able future?

According to tech news website Android authority, the necessary displays were difficult to produce. In 2012, nine out of every to OLED screens produced were 【小题9】. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these fold-able devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That’s a price that may 【小题10】 the majority of people.

But if the fold-able device isn’t going to change the world overnight, there is no doubt that it is coming.

Patrick Moor-head, an industry analyst told The Verge, “Few are debating if fold-able or roll-able mobile displays are the future of smart-phones; the only question is when and by whom.”
