Facebook CEO Zuckerberg just had a baby girl named Max, and to honor the occasion, he's giving away the majority of his wealth. In the letter{#blank#}1{#/blank#}(write) by Zuckerberg and his wife, Priscilla Chan, to{#blank#}2{#/blank#}(they) new baby girl, he announced the birth of his first child and the{#blank#}3{#/blank#}(create) of the Chan Zuckerberg Fund，{#blank#}4{#/blank#}will focus on curing disease, connecting people and{#blank#}5{#/blank#}(build) strong communities.

    “For your generation to live in{#blank#}6{#/blank#}better world, there is so much more our generation can do,” Zuckerberg wrote. “Today your mother and I are committing to spend our lives doing our small part to help solve these challenges.” The couple{#blank#}7{#/blank#}(donate) nearly all of their Facebook stock to the cause. “We will give 99% of our Facebook shares-currently about $45 billion-to advance this{#blank#}8{#/blank#}(value) mission,” he wrote. “We know this is a small contribution compared{#blank#}9{#/blank#}all the resources and talents already working on these issues. But we want to do{#blank#}10{#/blank#}we can, working along with many others.”

    I won't call myself the most accomplished person when it comes to {#blank#}1{#/blank#} (hold) chopsticks. In fact, I'm pretty sure that my technique looks clumsy at times. I tend to hold {#blank#}2{#/blank#} (I) in the middle, more beginner than expert.

    Still, since I eat almost every meal with the eating utensil(器皿)of choice in China it's not uncommon for a new friend or acquaintance to come to a simple {#blank#}3{#/blank#} (conclude) after observing me that my Chinese husband, Jun, must {#blank#}4{#/blank#} (show) me how to use them.

    They are wrong. I've used chopsticks ever since I was a teenager, a time when my sister and mother were both fond of Chinese cuisine and introduced me {#blank#}5{#/blank#} many new dishes, along with the {#blank#}6{#/blank#} (prefer) utensils in China. We always kept bamboo chopsticks along with our {#blank#}7{#/blank#} (knife), forks and spoons, ready for whenever we happened to have Chinese food for dinner. It was my closest family {#blank#}8{#/blank#} observed my first mistakes I made in using chopsticks.

    Plus, I lived over two years in China before Jun and I started dating and I {#blank#}9{#/blank#} (expect) to use chopsticks in almost every restaurant, stand and bar. Trust me, when you're hungry you figure out pretty fast what it takes to down(咽下) {#blank#}10{#/blank#} meal with these utensils.

    Modern-day robots are programmed to handle tasks that are normally carried out by humans. They are faster and{#blank#}1{#/blank#}(accurate) than human workers and never ask for a pay rise or take breaks!

    Robots are also able to work{#blank#}2{#/blank#}dangerous situations.

    Researchers at the University of Arkansas in the United States say that the mobile robots which have been created already are ideal for the job of hospital attendants. These mobile robots store a{#blank#}3{#/blank#}(detail) map of the hospital in their memory. The robots' sensors can detect{#blank#}4{#/blank#}(object) and quickly get out of the way. Although these robots cannot go up and down know how{#blank#}5{#/blank#}(press) a button of an elevator.

    Researchers at a Massachusetts' university are creating the first robot {#blank#}6{#/blank#}can constantly change its shape according to the task it has to do. These are called polymorphic robots. "Polymorphic" means{#blank#}7{#/blank#}ability to take different forms. A 3D printer{#blank#}8{#/blank#}(place) inside the robot to create the desired shape. The entire process of changing forms in this manner is called the rapid printing technology which is{#blank#}9{#/blank#}(fair) common in the car industry to produce complex 3D structures quickly. Once the robot has performed{#blank#}10{#/blank#}(it) task, it can be melted down and recycled into another useful part by the 3D printer.

    Raron Weaver was born on April 14^th, 1998 with only his left eye. It was very likely that this disability would come with brain damage. The chances are {#blank#}1{#/blank#} he would have brain damage, yet he didn't. He went through 25 operations and {#blank#}2{#/blank#} (receive)a false eye.

    When he was in the 4^th grade he dreamed of {#blank#}3{#/blank#}(become)a writer and he carried that dream with him throughout his life. However, he faced a great many {#blank#}4{#/blank#}(difficulty).

    From his first day of preschool to his last day of high school, he was looked at{#blank#}5{#/blank#}(strange)by others. People would call him names like "cyclops(独眼龙)" and would tell him that he was {#blank#}6{#/blank#} mistake. Along with this, suffering from obsessive compulsive disorder(强迫症)made it difficult for him{#blank#}7{#/blank#}(do)normal activities.

    In 2016 he graduated from high school with the support of a loving family {#blank#}8{#/blank#} the help of teachers and friends. He began to write a book and a year later he completed his book. In late2017 The Human Apocalypse{#blank#}9{#/blank#} (publish) and it is now being sold through several {#blank#}10{#/blank#}(difference) ways.

    You may not have noticed it before, but many people often sit with a hunched (驼背的) back when they are in a difficult situation, such as trying hard {#blank#}1{#/blank#} (solve) a math problem. But there's a reason for this: this body position helps to reduce pressure.

     However, according to Erik Peper, a health professor at San Francisco State University, poor posture (姿势) may make our brains work not as well as they {#blank#}2{#/blank#} (normal) do.

    Peper and a team of researchers {#blank#}3{#/blank#} (study) 125 students' performance in a math test and their different postures. The team found that good posture—for example sitting up straight—could help people perform better {#blank#}4{#/blank#} bad posture when they feel stressed.

    Another professor Richard Harvey further explained in Science Daily that sitting with bad posture might make us feel more {#blank#}5{#/blank#} (comfort), but it actually increases our pressure levels.

    So the next time you have to take a test, try sitting upright and taking a deep {#blank#}6{#/blank#} (breathe). If Peper's study is correct, this small change may have {#blank#}7{#/blank#} great influence on you.

    There are many things {#blank#}8{#/blank#} lead to poor posture. The good news {#blank#}9{#/blank#} (be) that posture can be improved at any age by {#blank#}10{#/blank#} (make) just a few simple corrections in the way one stands, sits and moves.
