(B)
My name is Mark, and it all started during a manned mission to Mars. A terrible dust storm hit us. My crew members believed I was killed in the accident. Following our emergency plan, they had to leave Mars quickly. So, they left, thinking I was dead. But I wasn't.
When I woke up, I was injured and alone. The communication system was destroyed. I was left on Mars with no way to contact the Earth or my crew. Everyone thought I was dead. I had a habitat designed to last for 31 days, but the next mission to Mars was four years away. The food I had would only last for about a year.
My first thought was: "I'm probably going to die here." But I quickly decided, "I'm not going to give up. I'm a botanist. I'm going to use science to get myself out of this." So, I got to work. I used my knowledge to do something crazy—I turned the Martian habitat into a farm. I planted some potatoes for a festival dinner. I used our waste to make soil. I calculated every drop of water and every bit of oxygen.
It wasn't easy. Disasters happened all the time. Once, a leak destroyed my potato farm. Another time, an explosion broke my habitat. Every time, I had to fix the problem with the limited tools I had.
Meanwhile, on Earth, people at mission control made a discovery. A scientist saw satellite photos and noticed signs of life on Mars! They realized I was alive. They started working on a way to bring me home. In the end, it was a crazy, daring plan and the courage of my crewmates that saved me. They turned their ship around and came back for me.

解析
【分析】做这类英语阅读理解题，需先通读全文把握主旨，再针对每个小题的关键词回到原文定位对应内容，对比选项与原文信息排除错误选项；词义猜测题要结合上下文语境推断词义，人物评价题需梳理人物行为总结品质。
【解析】
46题：题干问Mark被留在火星的原因，定位原文第一段：“A terrible dust storm hit us. My crew members believed I was killed in the accident... they left, thinking I was dead.”可知他的组员以为他在事故中死亡才离开，对应选项B。A选项“没告诉他”与原文不符；C、D原文未提及，故选B。
47题：题干问Mark在火星的主要问题，定位原文：通讯系统被毁（无法联系求助，对应b）；栖息地仅能维持31天，下一次任务需四年后（栖息地撑不久，对应e）；食物虽能撑一年但远不足够到下一次任务（对应c），故b、c、e正确，选B。
48题：词义猜测题，“botanist”后提到他用知识种土豆、改良土壤，结合语境可知是植物科学家，对应选项A。B是工程师、C是土豆农民、D是食物专家，均不符合，故选A。
49题：题干问地球人发现Mark活着的方式，定位原文第五段：“A scientist saw satellite photos and noticed signs of life on Mars!”对应选项C。A、B、D原文未提及，故选C。
50题：题干问Mark的特点，他遭遇困境不放弃，用科学解决问题，体现聪明且擅长解决问题，对应选项C。A“好运”、B“喜欢火星生活”、D“放弃希望”均不符合，故选C。
