The costs can be as high as $250 million or more. Most members of the design teams have worked in the field for a long time. They hold advanced degrees(学历) in math, science, or engineering.But things are changing. High costs, unusual educational needs and long start-up times are no longer an obstacle(障碍) to space exploration. The scientists have developed a new type of tiny, inexpensive earth-orbiting(轨道) satellite.So far, college students have built and launched(发射) several cube-shaped satellites, or CubeSats. At least 15 more are ready to go. Those already in orbit take pictures, collect information and send it back to the earth, just as regular satellites do. But you might not even have to wait until you get to college to start designing and building your own satellite. A new program called KatySat aims to get teenagers to take part in. When kids understand what satellites can do, the kinds of ideas theyll come up with may be_.Education isnt the only aim of CubeSats because these tiny, technology-filled boxes are inexpensive to build and can be put together quickly, theyre perfect for testing new technologies that might one day be used on major space tasks.The biggest challenge now is to find ways to bring the satellites back to the earth after a year or two. Or space junk could gradually increase because CubeSats become more popular.Nowadays, college and high school students are getting a chance to learn what it takes to explore in space. Somedayperhaps a lot sooner that you imagingyou might get to design, build and launch your own satellite. If you do, youre sure to have fun. And you might also get crazy about science for life.26 . Building a traditional satellite _.A. costs $250,000B. needs college studentsC. takes quite a long time27 . Compared with the traditional ones, the new satellites _.A. need long start-up timesB. are cheap and small-sizedC. collect more junk in orbit28 . The underlined word “countless” in Paragraph 4 probably means “_”.A. 无用的 B. 无价值的 C. 无数的29 . According to the passage, which of the following is true?A. CubeSats could possibly cause pollution in space.B. Scientists designed CubeSats for kids to play with.C. Students cant design satellites without college education.30 . The purpose of the author writing the passage is _.A. to tell us that satellite technology can also be learned by kidsB. to show that high technology brings a big change in kids lifeC. to tell us that kids must study hard to learn satellite technology 2019 marks the first year of the global commercial use of 5G. China is running ahead in this field. In March, 2019, the Shanghai Hongqiao Train Station became worlds first “5G train station”. Whats more, with the technology, it takes only 20 seconds to download a long movie. China is hopeful that we can even experience driver-less cars in daily life soon. However, the great technology is still new to most of us. What are the advantages (优势) of 5G? Here are some ideas. It is faster, for sure. It is expected to be at least 10 times faster than 4G. The first 5G modem (猫,调制解调器) of the IT company Qualcomm supports (支持) speeds of up to 5 Gigabytes (千兆字节) per second. Most of us have never experienced anything close to that speed. And we are only talking about the first generation of 5G modems. Future modems are likely to be even faster. But 5G is not all about speed. Have you ever been to a large event where your data (数据) connection slowed down? That is because 4G networks can only support a certain number of devices (设备) per square (平方) meter. 5G networks can do much better. They can support up to a million devices per square kilometer. Are you looking forward to that 5G world now? Get ready for the amazing future.31 . If we put the passage into 3 parts, which is the best?A/B/C/D/32 . Paragraph 4 shows the advantage of 5G by _.Agiving adviceBhaving a large eventCcomparing (比较) 5G with 4GDtalking about our prediction33 . What can we infer (推断) from the passage?AShanghai is the first city to use 5G.B5G will help us live and work better.CDriver-less cars will be much cheaper in the future.D5G networks can support up to a million devices per square kilometer.34 . After reading the passage, we can know the writer _ 5G technology.Adoesnt mindBis worried aboutCdislikesDlikes四、单词填空The human brains power could compete with any machine. And now a group of scientists from across Europe are trying to build one using the worlds most p35 . computer.Our brains have 100 billion neurons Each one performs billions of calculations seconds36 . to a desktop computer.So the brain computer will need to be able to do a billion calculations.Finding a way to power the supercomputer will be one of the Scientists major challenges. They hope to c37 . it within 12 years.Group leader, Professor Henry Markram, said, “The billions of interconnected neurons make it hard for us to truly understand how the brain works. Simulating it will make it much e38 . allowing us to operate and measure any aspect of the brain.”The brain will be built in facility in Germany. It will have thousands of 3D images, so scientists can “fly” around different areas and w39 . how they communicate with each other.If the “brain” works, it will help scientists understand brain diseases such as Parkinsons, and know more about how we think and make d40 . .There are concerns about the consequences of the computers which can think for themselves. But Professor Markram said “This is one of the t41 . great challengers for humans. We need to understand earth, space and the brain. We need to understand what makes us human.”五、多任务混合问题阅读下面的短文，将划线部分译成英文或中文。Five Ideas for Better SleepMost people need about eight hours of sleep each night. 65.但很多人睡眠有问题.If we dont have enough sleeping time, it will be bad for our work and study.
