五、翻译。
51．他努力尝试想要融入这群有冒险精神的少年中。(fit)
【答案】He tried so hard to fit in with/get involved in the group of teenagers with a sense of adventure.
【详解】考查动词短语和时态等。表示“努力尝试”可用try so hard；句子描述过去发生的事，时态用一般过去时，动词使用过去式形式，表示“想要融入……”可用fit in with或get involved in，使用动词不定式作目的状语；表示“这群有冒险精神的少年”可用the group of teenagers with a sense of adventure。整句话翻译为“He tried so hard to fit in with/get involved in the group of teenagers with a sense of adventure.”。故翻译为：He tried so hard to fit in with/get involved in the group of teenagers with a sense of adventure.
52．在未来，我会寻找更多的机会去练习我的英语口语。
【答案】I’ll seek more chances to practice my spoken English in the future.
【详解】考查时态和固定短语。“在未来”为“in the future”，常与一般将来时“will do”连用，“寻找更多的机会”为“seek more chances”，“我的”为“my”，“英语口语”为“spoken English”，“做某事的机会”为“ chances to do”，主语“我”为“I”，故“在未来，我会寻找更多的机会去练习我的英语口语。”翻译为I’ll seek more chances to practice my spoken English in the future.
53．为了更多地了解中国文化，汤姆决定报名参加一个汉语俱乐部。
【答案】To learn more about Chinese culture, Tom has decided to sign up for a Chinese club.
【详解】考查非谓语动词和时态。表示“更多地了解”短语为learn more about，此处为不定式作目的状语；表示“中国文化”短语为Chinese culture；主语为Tom；表示“决定”短语为decide to do sth.；表示“报名参加一个汉语俱乐部”翻译为sign up for a Chinese club；句子陈述已经发生的动作，且对现在造成了影响，应用现在完成时，主语是单数，助动词使用has。故翻译为To learn more about Chinese culture, Tom has decided to sign up for a Chinese club.
54．登上月球的第一人来自美国。
【答案】The first man to set foot on the moon comes from America.
【详解】考查短语、时态和非谓语动词。根据句意可知，本句描述现实状况，用一般现在时。表示“第一人来自美国”为the first man comes from America，come from“来自”是固定搭配；表示“登上月球的”为不定式短语to set foot on the moon作后置定语修饰man，含序数词的名词短语常用动词不定式作后置定语。句首字母大写，故翻译为The first man to set foot on the moon comes from America.
55．虽然这位环保主义者承受着巨大的压力，但他最终兑现了保护野生动物自然栖息地的承诺。（deliver）
【答案】Although this environmentalist was under great pressure, he ultimately delivered on his promise to protect the natural habitats of wildlife.
【详解】考查状语从句、固定搭配、非谓语动词和时态。根据句意可知，“承受压力”和“兑现承诺”表示的动作发生在过去，应用一般过去时。分析句子结构，“虽然这位环保主义者承受着巨大的压力”应用although引导让步状语从句。“环保主义者”可表示为environmentalist；“承受着巨大的压力”可表示为under great pressure；“最终”可表示为ultimately；“兑现”可表示为deliver on；“保护野生动物自然栖息地”可表示为protect the natural habitats of wildlife；“……的承诺”可表示为his promise to do...，不定式作后置定语。故本句可翻译为：Although this environmentalist was under great pressure, he ultimately delivered on his promise to protect the natural habitats of wildlife.
