拉进来确定是个零食。看这个孙悟空，好吧。一呢。一。呢？往东去往。东点过来。我等着呢，退呀退，好了。请了回来，快点回来看电视了。看看三大。白骨精，哎，师傅摸出来了，走吧。开点声开点声，开点声。来来活干事。我自己就很爱你。开，别开。 朋友们，太厉害了，我国正在量产马斯克，美国宇航局局长害怕了，这是让西方害怕的一组数据。我国歼十研发团队平均年龄36岁间，20团队平均年龄35岁间，35团队平均年龄32岁，墨子号团队平均年龄33岁，fast的团队平均年龄30岁，和鹊桥卫星一起绕月飞行的哈工大龙江二号卫星团队平均年龄竟达到了惊人的24岁，外国网友看到都惊呆了，直呼中国航天太年轻了。大家要知道啊，微软美国团队平均年龄是40岁，苹果研发团队平均年龄是51岁，NASA研发团队平均年龄是53岁，波音研发团队平均年龄是55岁。大家还记得日本火箭发射失败后鞠躬道歉吗？画面里的研发人员个个头发花白，老态龙钟，透着一股人才断层的无奈。年轻对于科研是多么的重要。俞敏24岁开是研究核物理，34岁开始研究氢弹，钱学森36岁就成为麻省理工学院最年轻的终身教授。不得不感叹，少年强则国强。中国任何一次航天发射，放在任何一个国家都能载入史册。天舟神舟逐梦路上，是一代又一代航天人的努力。致敬年轻的中国航天人。 You need five Young inventors. You may think that all inventors are adults with rich experience and university degrees, but you would be wrong. In fact, many famous inventions have been created by teenagers, just like you helping the blind to read. At the age of three, lis brill became blind as a result of an accident. As a school for the blind, he was told to read using books with raised letters. Blind people would run their fingers over the letters and guess their shapes. However, sometimes IT was confusing because letters like you and over very similar, and they also took up too much space on a page to solve these problems. A system was invented where letters were replaced with the code of race dots. However, this new method was still slow and difficult. At the age of fifteen, brail made important improvements to the raised dot system. He made the code simpler and reduced the number of raised dots. Brails system was incredibly successful and is still used today around the world. Bringing entertainment to our homes in nineteen and twenty one fellow, far worth was fourteen years old when he read about the problem of creating an electric television in a science magazine and became interested in IT. One day, while he was working on a farm, he noticed the straight rose of crops, and IT gave him an idea. Perhaps an image could be broken down into lines, changed into electronic signals and then sent through the airwaves. For years, far worth worked to develop his ideas, but he faced many chAllenges along the way. Many people did not believe his idea would work, and he found IT difficult to get money to pay for his research. However, he never gave up when he was twenty one. He eventually succeeded in sending a simple image using his invention. This breakthrough was an important step in creating the modern television that we use entertainment today. These stories show that with a passion for solving problems, anyone can make a difference in the world no matter how old they are. So if you have an idea that you believe in, do not be afraid to go for IT. Who knows? You may just be the next Louis brill or fellow farms words.
