All scientists subscribe {#blank#}1{#/blank#} the view that it is human activities that have caused the global warming. Huge {#blank#}2{#/blank#} (quantity) of carbon dioxide produced by burning fuels like coal,  natural gas and oil {#blank#}3{#/blank#} (result) in the "greenhouse effect". All scientists also agree that the levels of carbon dioxide keep on {#blank#}4{#/blank#} (increase), so more heat energy tends to be {#blank#}5{#/blank#} (trap) in the atmosphere. {#blank#}6{#/blank#} the scientists have different attitudes towards this phenomenon. On the one hand, some think the {#blank#}7{#/blank#} of increasing the temperature by 5 degrees would be a catastrophe. On the other hand, others are {#blank#}8{#/blank#} to this view and believe that there will be few bad environmental {#blank#}9{#/blank#} caused by more carbon dioxide. On the contrary, they think it will be beneficial to plants, crops and a greater range of animals, {#blank#}10{#/blank#} will make people's life better.

    Marty is a disabled boy{#blank#}1{#/blank#} suffers from a muscle disease. Sometimes he is too weak{#blank#}2{#/blank#}(run) or climb stairs as quickly as other people. The doctors don't know {#blank#}3{#/blank#}(exact) what is wrong with him. Luckily, Marty has learned to adapt {#blank#}4{#/blank#} his disability. In order to make his life happy and{#blank#}5{#/blank#} (satisfy), Marty keeps busy doing things that do not require physical strength. He has friends with {#blank#}6{#/blank#} he can go to movies and football matches and he has lots of pets. He used to dream of one day being a famous football player and {#blank#}7{#/blank#} (represent) his country in the World Cup. Even when he is made fun of, he doesn't get {#blank#}8{#/blank#} (annoy). Disabled{#blank#}9{#/blank#} he is, Marty has become stronger and more independent. He never feels sorry for himself and he enjoys as rich and full a life as everyone else.

    He suggests that we normal people should give the disabled {#blank#}10{#/blank#} (encourage) rather than laugh at them.

One day, Mary was working in her office in London {#blank#}1{#/blank#}she received an email from her friend Joan. In Joan's email, she persuaded Mary {#blank#}2{#/blank#}(look) for a flat in London for her. As she had {#blank#}3{#/blank#} (little) money than before, the flat had to be cheap, but it had to be modern, with elevators and gas lines. Though Mary found {#blank#}4{#/blank#} difficult to find such a flat, she still went from one block to another, looking for a flat {#blank#}5{#/blank#} would meet Joan's requirements(要求). Having tried too many times, Mary came up {#blank#}6{#/blank#} her boss and asked him for advice {#blank#}7{#/blank#} (polite). It was the first time that she {#blank#}8{#/blank#} (talk) with her boss about her personal problems. It happened that the boss just had such a flat for rent, so they quickly reached {#blank#}9{#/blank#} agreement. But to her surprise, when she emailed Joan, telling her the good news, Joan said that she had changed {#blank#}10{#/blank#} mind— she was not going to London.

    With the passing of 2018 and Spring Festival, we{#blank#}1{#/blank#}(start) a new important year already.

    This year is one of the final stepping stones to becoming a{#blank#}2{#/blank#}(moderate) prosperous society in 2020. Meanwhile, 2019 marks the 70th anniversary of the founding of the People's Republic of China. To prepare for 2019, the government made{#blank#}3{#/blank#}(it) economic agenda (事项) clear at the Central Economic Work Conference,{#blank#}4{#/blank#} (attend) by the country's leaders in Beijing in December.

    Great attention will keep on{#blank#}5{#/blank#}(pay) to China's growth performance in 2019. To meet the target of doubling 2010 GDP by the end of 2020, it needs to average about 6.3 percent this year and next.

    Meanwhile, China will host the second Belt and Road Forum for International Cooperation in April. At this event, the Belt and Road Initiative,{#blank#}6{#/blank#}has huge potential to drive economic growth, will take greater shape.

    This year is also likely to pave the way for a number of technological{#blank#}7{#/blank#}(advance). China is expected to roll out 5G, the next generation of{#blank#}8{#/blank#}(wire) technology, next year. It's up to 100 times faster{#blank#}9{#/blank#}the current 4G technology.

    It will be a year for China to reflect{#blank#}10{#/blank#}its past and future direction,

    One sentence from the news in Washington has remained in my mind since a trip last summer: "When you see people run against the crowd escaping{#blank#}1{#/blank#}the danger, they are {#blank#}2{#/blank#}(probable) firefighters, police or journalists.

    I think this is most true for the firefighters. Whenever and wherever {#blank#}3{#/blank#} (disaster) happen — 911 Attacks in New York 14 years ago or the explosion in Tianjin on Wednesday night — it is always the firefighters{#blank#}4{#/blank#}take the lead to run to the very center, saving lives by{#blank#}5{#/blank#} (risk) their own. I cried today near the explosion site, not because of the smoke from the ongoing fire {#blank#}6{#/blank#} because of a short message a firefighter sent to a trusted friend that went viral online. It reads, "If I cannot make it, my father is {#blank#}7{#/blank#}(you); and please remember{#blank#}8{#/blank#}(sweep) my mother's tomb." I was thrilled later to learn that he did make it.

    “Everyone knows it's {#blank#}9{#/blank#} (danger) to be a firefighter. But he has always liked it and has done it for 12 years," his father said. "He survived this time, but no one knows what{#blank#}10{#/blank#} (happen) next time.”
