    On May 18, it was announced that China had achieved success in drilling fire ice, a frozen {#blank#}1{#/blank#}(mix) of water and natural gas, from the South China Sea. {#blank#}2{#/blank#}(official) known as methane hydrates(甲烷水合物), fire ice produces a high amount of energy when {#blank#}3{#/blank#}(burn) and its chemical reaction produces nothing but dioxide and water.

    Fire ice, both clean and energy-intensive, {#blank#}4{#/blank#}(consider) the fuel of the future. Many countries, including the United States and Japan, have long been conducting research on fire ice, but extracting（提取）it from the bottom of the sea has been a common problem {#blank#}5{#/blank#}(trouble) all of them. But, the Chinese team succeeded in drilling fire ice for nearly eight successive days, {#blank#}6{#/blank#}is a big breakthrough.

    However, it is too early {#blank#}7{#/blank#}(say) a new energy source has been found. The world's total fire ice reserve is about 21,000 trillion cubic meters, which, if extracted, could meet the world's energy need

    {#blank#}8{#/blank#}1,000 years. But the successful test drilling of fire ice does not mean it can be extracted for {#blank#}9{#/blank#}(industry) use. China has to solve many problems before it can use fire ice as a source of energy.

    It's thought that only by 2025 at{#blank#}10{#/blank#} earliest might people be able to look at realistic commercial options.

    Two traveling angels stopped to spend the night in the home of a wealthy family. The family was rude and refused{#blank#}1{#/blank#} (let) the angels stay in the guest room. Instead the angels{#blank#}2{#/blank#}(give) a space in the cold basement. {#blank#}3{#/blank#}midnight the older angel saw a hole in the wall and repaired it. When the younger angel asked why, the older angel replied: Things aren't always what they seem.

    {#blank#}4{#/blank#} next night the two angels came to rest at the house of a very poor, but very hospitable(好客的)farmer and his wife. After sharing their food, the couple let the angels sleep in their only bed .As {#blank#}5{#/blank#}(usually), the angels found the farmer and his wife in{#blank#}6{#/blank#} (tear). Their only cow died. The younger angel was very angry and asked the older angel, "Why did you not care about the poor family? The first man had everything, yet you watched over his house. The second family had little but was willing to share everything, but you did not help."

    {#blank#}7{#/blank#} (final)the older angel replied. "When we stayed in the basement, I noticed there was gold kept{#blank#}8{#/blank#} the hole . Since the owner was so greedy and unwilling to share his good fortune, I asked God if I could seal(封口) the wall so he wouldn't find it. Then last night as we slept in the farmer's bed, the angel of death(死神) came for his wife. I made up {#blank#}9{#/blank#}mind to help them, so I gave him the cow instead of the farmer's wife. Just remember that things aren't always {#blank#}10{#/blank#}they seem."

    The astronauts will spend 30 days on the Tiankong-2. They plan to perform {#blank#}1{#/blank#}(science) and spacecraft-related experiments and test systems for a future space station. In{#blank#}2{#/blank#}words, the Tiankong-2 laboratory will not be part of that space station. Its main goal is to practice the techniques and the{#blank#}3{#/blank#}(technology) that they will be{#blank#}4{#/blank#}(use)to build and operate that final space station.

    Ahead of this year's London Book Fair in March, media reported a rise in interest in translated works among British readers. For translator Anna Holmwood, this signals the {#blank#}1{#/blank#} (arrive) of a new era.

    "This is a big moment for Chinese fiction abroad," says Holmwood, {#blank#}2{#/blank#} has translated Chinese literature for almost a decade.

    Her translation work, Legends of the Condor Heroes, a fantasy novel written by Jin Yong, and Liu Cixin's science-fiction book, The Three Body Problem, are shown in a Nielsen report {#blank#}3{#/blank#} examples of two of the most popular Chinese fiction works in Britain in 2018.

    "Languages in growing demand include Chinese and Arabic." according to the Nielsen report. It found that, against the commonly {#blank#}4{#/blank#} (see) "not more than 3 percent rule" of translated literature's presence in the English-language book markets, the number for 2018 was 5.63 percent in Britain {#blank#}5{#/blank#} the total annual sales was worth $27.1 million.

    Charlotte Collins, translator and co-chair of the British Translators Association, says: "As we can see, this proportion (比率) {#blank#}6{#/blank#} (double) in recent years... This is {#blank#}7{#/blank#} (real) exciting news."

    The Guardian quotes (引用) Fiammetta Rocco, administrator of the Man Booker International Prize, "{#blank#}8{#/blank#} (read) fiction is one of the {#blank#}9{#/blank#} (good) ways of putting ourselves in other people's shoes. The rise in sales of translated fiction {#blank#}10{#/blank#} (show) how hungry British readers are for terrific writing from other countries."
