    Have you ever wondered{#blank#}1{#/blank#}children always seem to have bas of energy and never run out of steam? Researchers have discovered that children have levels of recovery of endurance athletes. In fact, scientists say children's muscles recover from "high-intensity exercise" a lot {#blank#}2{#/blank#}(quick)than athletes. A study looked at the performance levels of children when they were cycling, and compared their fitness to {#blank#}3{#/blank#} of athletes. Rwsearcher Dr Sebastien Ratel suggested they{#blank#}4{#/blank#}(find)the children used more of their aerobic metabolism and were therefore less tired during the high-intensity physical activities. The children also recovered very quickly—even faster than the well-trained adult endurance athletes.

    The researchers hope that{#blank#}5{#/blank#}(they)finding will help scientists have a better {#blank#}6{#/blank#}(understand) of how the human body changes with age. It could lead to advantages in the fight{#blank#}7{#/blank#}diabetes and other diseases. Dr Ratel said the research was{#blank#}8{#/blank#}(particular)important as more children were become less active. He warned."

    Two new satellites of BeiDou Navigation (导航) Satellite System (BDS){#blank#}1{#/blank#}(send) into space on a Long March-3D carrier rocket from the Xichang Satellite Launch Center in Sichuan Province, China at 2:07 a.m. on November 19, 2018. The satellites entered a Medium Earth orbit (轨道) {#blank#}2{#/blank#}(safe) more than three hours later and will work with 17 other BDS-3 satellites already in space. They are also the 42^nd and 43^rd{#blank#}3{#/blank#}(member) of the BDS satellite family.

    China launched these satellites with the aim of providing navigation services{#blank#}4{#/blank#}countries and regions which participate in the Belt and Road Proposal by the end of 2018. “This is a key and{#blank#}5{#/blank#}(value) step for BDS developing from a Chinese experimental system to a regional and then a global navigation system,” said Yang Changfeng, chief expert{#blank#}6{#/blank#}contributed much to the BeiDou system. The positioning{#blank#}7{#/blank#}(accurate) of the BDS-3 system has been improved to 2.5 meters to 5 meters, said Yang.

    {#blank#}8{#/blank#}(name) after the Chinese term for the Big Dipper, the BeiDou system has been serving China for 18 years where another six BDS-3 satellites will be put into the Medium Earth orbit from 2019 to 2020. The system is expected{#blank#}9{#/blank#}(provide) first-class services around{#blank#}10{#/blank#}globe by the end of 2020.

    Mac was cycling along a road. With a heavy camp bag, he wasn't moving very fast. Suddenly he heard loud breathing behind him. {#blank#}1{#/blank#} (look) to his side, he was {#blank#}2{#/blank#} (terrify) to find it wasn't a dog but a wolf that was running after him. He reached {#blank#}3{#/blank#} the spray in the bag. With one hand on the handlebar, he fired it. A bright red color covered the wolf and it fell back shaking its head. But a minute {#blank#}4{#/blank#}(late) it was by his side again. He sprayed {#blank#}5{#/blank#} second time, the wolf falling back again but only to quickly restart {#blank#}6{#/blank#} (it) attack. The wolf was getting closer. Mac waved and yelled at passing {#blank#}7{#/blank#}(motorist) but meanwhile rode hard. He knew clearly he must be careful not to slow down. {#blank#}8{#/blank#}(fortunate) , Paul and Becky were driving along the same road when they spotted the scene. They drove toward Mac. When the car was in front of him, Mac jumped off the bike and dashed for the back door. Paul {#blank#}9{#/blank#}(open) the door so as to let Mac in.
