In 1969, Armstrong {#blank#}1{#/blank#}(successful) set foot on the Moon. This was {#blank#}2{#/blank#} first time anyone had walked on the surface of another world. More astronauts（宇航员）reached the Moon later, but nobody {#blank#}3{#/blank#}(visit) it since 1972. Do you think it's time we went back?

    {#blank#}4{#/blank#}(explore) of the Moon did continue after the astronauts left, but by robots instead {#blank#}5{#/blank#} people. Satellites have helped us learn more about our neighbour and shown that there {#blank#}6{#/blank#}(be) even more exploring to do, but astronauts would be needed!

    The problem is that sending humans to the Moon is very expensive. Even with all the new technology since Armstrong's time, it would cost so much for people {#blank#}7{#/blank#}(return) to the Moon.

    ESA (European Space Agency) wants to change that. ESA's idea isn't just to make the spaceships {#blank#}8{#/blank#}(they), but also to work with businesses here on Earth. ESA also wants to help businesses on Earth develop tools and technology {#blank#}9{#/blank#} will allow people to live on the Moon. If we can use resources（资源）on the Moon, then journeys there will be much {#blank#}10{#/blank#}(cheap). For example, what if we could get to water hidden deep within Moon rocks?

    I will never forget that at the age of nine I was asked to deliver a speech entitled A Challenge in My Life before the whole class!

    You can imagine how{#blank#}1{#/blank#}(terrible)shy I was the moment I thought of that—with so many eyes{#blank#}2{#/blank#}(fix) upon me. I have no choice but{#blank#}3{#/blank#}(prepare) for it, though. First, I was to draft the speech, which was just a piece of cake for me, a good writer. But the hardest part{#blank#}4{#/blank#}(lie)in my oral presentation from my memory, for to read from the paper was not allowed. The real moment began {#blank#}5{#/blank#} I stood on the platform with my legs trembling and my mind blank. But my {#blank#}6{#/blank#} (listen) were waiting patiently without any signs of rushing me. Gradually I found myself back. After {#blank#}7{#/blank#} seemed to be a hundred years, I found my audience applauding匢 made it! From then on, my fear of talking before {#blank#}8{#/blank#} big audience disappeared. Actually with my confidence building up, I now turn out to be a great speaker. Looking back, I know the greatest difficulty on our way {#blank#}9{#/blank#} success is our fear. Overcome it, {#blank#}10{#/blank#} you will be able to achieve your goals.

    How are you getting along with your senior high school? It may be hard for you as this is the first time that you {#blank#}1{#/blank#}(leave) your parents. I know that you are now having trouble {#blank#}2{#/blank#}(communicate) with others, and you may often feel lonely. That's {#blank#}3{#/blank#}you are new here and people don't know about you. But I think you can overcome the difficulty if you can follow the advice below.

    First, you should attach great {#blank#}4{#/blank#}(important) to taking an active part in the discussions and show your own opinions about the matters, and at the same time, learn to listen to other people's views {#blank#}5{#/blank#} (careful). Second, you should learn about your classmates' likes and dislikes,{#blank#}6{#/blank#}can make you get familiar with them. Only in this way can you get to know more {#blank#}7{#/blank#}(difference) people and show them that you are just as friendly. Last but not least, I'm always here ready to help. We can take part in some {#blank#}8{#/blank#}(activity) together and I can introduce you to others.

    There's no need {#blank#}9{#/blank#}(worry) too much, people will know you more very soon and will like to make friends with you if you can do {#blank#}10{#/blank#} the above. Just remember, "God helps those who help themselves".

    Man Kaur started running in 2009, {#blank#}1{#/blank#}she was in her 90s and began racking up medals. At 103, Man Kaur is not only going strong, she's getting others to follow in her footsteps as well.

    India's oldest female athlete is spending her summer {#blank#}2{#/blank#}(coach) 30 young athletes. Kaur and her 81-year-old son and trainer, Gurdev Singh, {#blank#}3{#/blank#} (invite) for two weeks to several universities, {#blank#}4{#/blank#}their methods made such an improvement in the students' performance that they were asked {#blank#}5{#/blank#}(stay) through September.

    This invitation came on the heels of Kaur's participation in the World Masters Athletics Championships in Poland earlier this year, where she {#blank#}6{#/blank#}(win) gold in all four events. Though she was the only {#blank#}7{#/blank#}(compete) in her age category for all four events, for the 60-meter dash, she had company from other categories: two 85-year-olds and three 90-year-olds. Though they weren't competing for the prize in her age bracket, they ran alongside her and {#blank#}8{#/blank#} (eventual) ahead of her.

    Ten years after she first started running, Kaur still loves it, according to her son. "She enjoys {#blank#}9{#/blank#}company of her admirers," her son adds. "Every time she participates, she feels proud that people around the world feel {#blank#}10{#/blank#}(inspire)."

    New Year in Chinese eyes is a family reunion. However, in foreigners' eyes, it is not only a kind of homesickness, but a spring migration(迁徙).Every year {#blank#}1{#/blank#} (see) the largest annual mass migration on the planet {#blank#}2{#/blank#} one sixth of the world's population travel home to celebrate {#blank#}3{#/blank#} their families. That is around a billion people {#blank#}4{#/blank#} (make) 3.5 billion journeys in a 40-day period. Meanwhile, over 250 million rail journeys are made across China during the festival.

    Last year, 5.6 million rail tickets {#blank#}5{#/blank#} (sell) in a single day. Every new year in the heartland of industrial China thousands upon thousands of motorcyclists brave the weather and hit the road, determined to make {#blank#}6{#/blank#} home.

    The Chinese New Year {#blank#}7{#/blank#} (celebrate) is also known as the Spring Festival. It lasts 15 days. It is the main holiday of the Chinese calendar. In modern China, {#blank#}8{#/blank#} (search) for work, many people have to move away from home. And they will travel home to be with the loved ones during the Spring Festival. In Chinese New Year, modern and {#blank#}9{#/blank#} (tradition) customs are brought together when the Chinese celebrate the Spring Festival. Nowadays, not only does China have the {#blank#}10{#/blank#} (fast) growing modern cities in the world, but the landscapes are also truly diverse.

    Since {#blank#}1{#/blank#} first fully artificial plastic was invented in 1907, humans {#blank#}2{#/blank#}(find) innumerable uses for the material. It has found {#blank#}3{#/blank#}(it) way into our tools, our clothes and even our bodies. In a new study in {#blank#}4{#/blank#}(environment) science and technology, researchers estimate the average American eats more than 50,000 pieces of microplastic particles, {#blank#}5{#/blank#}(small) than 5 millimeters in length every year and breathes in another 50,000. Although the health {#blank#}6{#/blank#}(effect) of consuming these tiny bits of plastic are unclear, researchers stress the real volume that people are {#blank#}7{#/blank#}(casual) swallowing is alarming. The largest contributor came {#blank#}8{#/blank#} drinking bottled water, in {#blank#}9{#/blank#} the bottle itself added more than 32 times more plastic to a diet {#blank#}10{#/blank#}(compare) with tap water, The Guardian reports.
