    Here, let me share one of my experiences with you. When I was a ten-year-old girl, I was once asked to deliver a speech titled “A Real Test in My Life” before the whole class! Just 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 had no other {#blank#}3{#/blank#}(choose), though. First I was to draft the speech and that was just a piece of cake for me, because I was a good writer — something to pride myself in. But the hard part {#blank#}4{#/blank#}(lie) in my oral presentation; to read from {#blank#}5{#/blank#} paper was not allowed; I had to give the speech from my memory and in front of such a big audience ! A real trial began when I stood on the platform with my legs trembling and my mind blank. How much time had passed by, I didn't know. My listeners were still waiting, patiently and without any signs of rushing me. Gradually I found {#blank#}6{#/blank#} (I) back，giving out my speech with difficulty. Finally I finished. After {#blank#}7{#/blank#} seemed to be a hundred years, I found my audience applauding. I made it! From then on, my fear of talking before an audience disappeared. Actually with my confidence building {#blank#}8{#/blank#}， I now turn out to be a great speaker.{#blank#}9{#/blank#} (Look) back, I know the greatest difficulty on our way to success is our fear; overcome it，{#blank#}10{#/blank#} we will be able to achieve our goals.

China's Chang'e 5 mission successfully delivered samples(样本)of moon rock and dust to Earth on December 17, 2020. It{#blank#}1{#/blank#}(mark) the first time in 4 years that moon rocks have been brought back to our planet, since the Soviet Union's I.una 24 mission in 1976.

The sample capsule landed in Inner Mongolia{#blank#}2{#/blank#}a little after 2：00 a. m. Recovery teams in trucks and helicopters located the landing site shortly after and secured the sample{#blank#}3{#/blank#}(contain).

While Apollo-era moon rocks are estimated to be about 3 to 4 billion years old, the material{#blank#}4{#/blank#}(collect) by Chang'e 5 is from a site in the northwest region of the moon's near side. This area was formed{#blank#}5{#/blank#}(late), and the rocks here are thought to be only about 1.2 billion years old. That means scientists could learn more about the evolution of the moon and test out new techniques for estimating the age of geological samples from other{#blank#}6{#/blank#}(planet)and moons(卫星).

The Chang'e lunar program, {#blank#}7{#/blank#}includes landing two lunar rovers(月球车)on the moon's surface, has been{#blank#}8{#/blank#}(remarkable)successful. Although Chang'e 5 was a short mission, it's one of{#blank#}9{#/blank#}most complex projects undertaken by the Chinese space program so far. The country is far from done with the moon—Chang'e 6, a second lunar sample return, is scheduled{#blank#}10{#/blank#}(launch) in 2023 or 2024.
