For instance, on Monday, you do push-ups(俯卧撑) to build up your arms, and on Tuesday, you build up {#blank#}7{#/blank#} (strong) in your legs by doing deep knee bends. {#blank#}8{#/blank#} exercise plan changes as time goes by.

    The best part of this app is that everyone can share {#blank#}9{#/blank#}. (they) workout results and follow their training. It is a great way for you and your friends {#blank#}10{#/blank#} (encourage) each other to build strong bodies.

    I was nine years old when I learnt to ride a bike. The bike was a birthday present from my uncle. You can imagine how{#blank#}1{#/blank#} (excite) I was when I saw the bike, and I begged my uncle to teach me how {#blank#}2{#/blank#} (ride) it right away. However, before I got on the bike, I felt {#blank#}3{#/blank#} (extreme)  nervous and l  was  afraid  that l  would  fall  off and hurt {#blank#}4{#/blank#} (me).My uncle held onto the seat and helped me to get {#blank#}5{#/blank#} the bike. While l was riding, he was running along beside me, holding the seat so I would not fall over. I was so{#blank#}6{#/blank#} (grate) to him for his help.

    As I was practicing, I became more and more confident. Then, I heard my uncle shouting, "You are riding it by yourself now!" I was both excited and scared. I was really riding by myself, but{#blank#}7{#/blank#} if I fell off? Could I use the brakes to stop? As I was wondering about this, my uncle ran after me and got hold of the bike. I{#blank#}8{#/blank#} (slow) down and came to a stop. My heart was still beating fast when I got off the bike. {#blank#}9{#/blank#} (late) that day, having learnt how to get on the bike and get off it, I felt like l was walking on air! I am still thankful to my uncle for teaching me to ride a bike on my {#blank#}10{#/blank#} (nine) birthday.

    Born in England in 1944, Ian Wilmut{#blank#}1{#/blank#}(know)as the leader of the research group that first cloned a female lamb {#blank#}2{#/blank#}(call)Dolly in 1996. Dolly became famous and pictures of her appeared on the{#blank#}3{#/blank#}(cover)of magazines all over the world. The{#blank#}4{#/blank#}(possible)of reproduction without a male and female being involved also made her the focus of a moral debate. For scientists, however, the cloning of dolly using the DNA of an adult cell was a breakthrough {#blank#}5{#/blank#}showed the cloning of special animals was possible.

    However,{#blank#}6{#/blank#}Wilmut thinks unlikely is human cloning. He says {#blank#}7{#/blank#}(undertake)the procedure with humans would require 29 surrogate(替代的)mothers and 300 eggs. Of those 29,28 would be bound {#blank#}8{#/blank#}(experience)failure and suffer physically and emotionally. He says he is also concerned about the psychological and{#blank#}9{#/blank#}(society)consequences a cloned might have to go through. For these reasons, he is not {#blank#}10{#/blank#}favor of it.

    Music is in the comers of everyday life. It is said to be {#blank#}1{#/blank#}(benefit) to us both physically and mentally.

    There are many ways to make music. For example, if you blow into bamboos or shells, {#blank#}2{#/blank#}(permit) air to come in, they can produce pleasant music. A recent discovery suggests that music is played much earlier than we think. In 1995, deep in {#blank#}3{#/blank#}cave in Slovenia occupied 45,000 years ago by Neanderthals, a leg bone of a bear with four finger holes was found, {#blank#}4{#/blank#} suggested that flutes（笛子）had come into {#blank#}5{#/blank#}(exist) at that time. Later, many other {#blank#}6{#/blank#}(tradition) musical instruments like drums were unearthed. Ancient people even {#blank#}7{#/blank#}(seek) a way to make music out of a bow that {#blank#}8{#/blank#}(intend) for hunting, so we have to admit that they did have a great gift {#blank#}9{#/blank#}music. But if accurately dated, the Neanderthal flute is by far the {#blank#}10{#/blank#}(early) known example of music.

    Now music can be found in every known culture, and even the most isolated（孤立的）groups have a certain form of music.

Yungang Grottoes (石窟) in Datong, Shanxi Province, are a world cultural heritage (遗产) site with a history that {#blank#}1{#/blank#} (go) back more than 1,500 years. In Yungang's 45 big grottoes and more than 200 small grottoes, roughly 59,000 figures of the Buddha, {#blank#}2{#/blank#} (be) a priceless treasure of human culture.

{#blank#}3{#/blank#}because of the effects of climate change and natural disasters, the grottoes face damage year after year. Thanks to {#blank#}4{#/blank#} (advance) digital technology, researchers are busy "duplicating" (复制) the Yungang Grottoes in an attempt to preserve the precious cultural relics (遗物). Employing 3D laser scanning technology, the researchers{#blank#}5{#/blank#} (digital) record the shapes, colors and other fine details of the grottoes and later reproduce{#blank#}6{#/blank#}by using 3D printing technology.

The new technology could enable more people{#blank#}7{#/blank#} (access) the cultural relics despite the distance. In June, 2020, the Zhejiang University Cultural Relics Research Institute and Yungang Grottoes Research Institute together "copied and pasted" Cave No. 12 of the Yungang Grottoes for an{#blank#}8{#/blank#} (exhibit) in Hangzhou, in which is the world's first 3D-printed 1:1 "copy" of a grotto.

These Yungang{#blank#}9{#/blank#} (researcher) attempt is a good example of technology helping to preserve cultural heritage. It is hoped{#blank#}10{#/blank#}the new digitalized technologies will facilitate the "rebirth" of the cultural relics, and bring them to more places worldwide.
