It seems like we39。re forever hearing about hackers leaking(泄露) s, passwords and other important personal information. But thanks to a breakthrough by Chinese scientists, who won the 2018 Newb Cleveland Prize in February, we may soon never have to worry about our data again. This is thanks to the satellite called Micius that uses cuttingedge technology to send and receive information. Micius is the first satellite of its kind to use quantum key distribution(量子密匙分發(fā)), which uses particles (粒子) that transmit(傳輸) light to transfer information from one point to another. Currently, it can municate with two base stations(基站), both of which are located high up in the mountains in two different areas of Tibet, around 1,200 kilometers apart. Data is sent between the satellite and one of the base stations in the form of a ray of light. This makes it almost impossible for data sent and received using quantum satellite technology to be stolen, as the connection will be broken if someone tries to hack it. Any eavesdropper(偷聽者) on the quantum channel attempting to gain information … can be found by the municating users, the scientists wrote in the paper. However, the technology does have a few limitations. For example, the process only works at night, as the information isn39。t able to pass through sunlight. Despite these small issues, the scientific munity across the world has reacted positively to China39。s achievements in this groundbreaking project. This Chinese experiment is a quite remarkable technological achievement, Artur Ekert, a professor of quantum physics at the University of Oxford, told BBC News. And Karl Ziemelis, an editor for Nature, told Xinhua, It39。s a testament(見證)to China39。s investments and significant efforts in the physical sciences that this group has been able to push research in practical quantum munication technologies to such an astronomical(天文學(xué)的)height.（1）According to the passage, why Micius is safe for transporting messages? A.Because it is only data base located in space, which cannot be touched.B.Because it only works at night, as the information isn39。t able to pass through sunlight.C.Because it uses particles that transmit light to transfer information from one to another.D.Because it doesn39。t score any important private information like passwords and s.（2）Which of the following can best describe scientists39。 words in the paper? A.It gave out the working principle of Micius.B.It tells of a kind of scientific appearance.C.It warned hackers not to steal information from Micius.D.It is a more apparent explanation of its safety.（3）What39。s the main problem of Micius? A.Its core technology is controlled in foreign countries.B.Light is a must in its working process.C.Its safety performance needs improving.D.Sunlight has a deadly influence on its working.（4）What39。s the best title of the passage?

What about snakes or spiders? Put those fears aside: because in the . you39。re far more likely to be killed or injured by a deer skipping across the road. Deer cause more than 200 humans deaths each year, plus some 29, 000 injuries, all because of million collisions between vehicles and deer. Most incidents occur in the eastern ., where deer prosper without natural predators like wolves and mountain lions. That39。s the region in the . where deervehicle collisions are such a problem, and where it seems like an effective large carnivore reintroduction could make a really big difference. says wildlife biologist Laura Prugh from University of Washington. She thinks it would help to reintroduce predators like mountain lions, also known as cougars, pumas or panthers, to parts of their historic range from which they39。ve been driven out. The researchers say that bringing the predators b
