【解析】

1.细节理解题。根据第三段I couldn’t even shout for help. Luckily my grandpa was going to the toilet and heard me falling out of bed. If it wasn’t for him, I probably wouldn’t be here.可知第二次心脏病发作时，多亏我的爷爷当时在场，我才幸免于难。故选C项。

2.细节理解题。根据第五段My whole world came crashing down, but I stayed strong.可知虽然我感觉到世界塌了，但是我依然选择坚强。也就是说为了生活继续与病魔斗争。故选B项。

3.推理判断题。根据最后一段的内容可知，作者因为新的心脏的移植，又重获了新生。作者当然是心存感激的。故选B项。

4.标题归纳题。文章主要讲述了作者患上心脏病，坚强地与病魔作斗争，最后终于等到了一颗新的心脏。故C项正确。

【备注】这是一则记叙文。文章主要讲述了作者患上心脏病，坚强地与病魔作斗争，最后终于等到了一颗新的心脏。

C

Humans have launched themselves into the outer space. They’ve landed on the moon. They’ve built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet – specifically, Mars.

The problem is that it’s no easy task. The planet is 586 times further away from the Earth than the moon, and it’ll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration (损耗).

Here’s where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could withstand the extreme g-force (重力) of a rocket launch.

Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They’re small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior.

Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS).

This experiment was part of a wider NASA mission (任务) called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission.

The mice have participated in 20 separate experiments, to study such effects as osteoporosis (骨质疏松症), anemia (贫血) and heart health.

Results for the 20 experiments are coming in gradually. But it’s clear that mice continue to play an important role in the ongoing quest to conquer the final frontier.

28. We can infer from Paragraphs 2-3 that ______.

A. Mars is the farthest planet away from Earth discovered so far

B. the journey to Mars could put humans’ health at risk

C. it was in the late 1940s that animals were first sent to the ISS

D. animals that have been sent into space have mostly survived

29. The underlined word “withstand” in Para.3 means _________.

A.set up B. hold up C. work out D. come across

30. According to Betty Nusgens and her team, the mice aboard the ISS ______.

A. suffered the loss of part of their skin

B. all survived for the duration of the mission

C. were fed and watered by the astronauts

D. participated in 20 experiments that made great breakthroughs

31. The main purpose of the article is to _____.

A. describe the role mice play in scientific research

B. report on the results of the Mice Drawer System
