Question

【题目】 Astronauts on board the International Space Station (ISS) once made history by taking bites of red romaine lettuce (长叶药昔）. They became the first humans to eat food that was grown entirely in space.

The lettuce was planted on the ISS in a small greenhouse called “Veggie”, which uses LED lights to help plants grow in space.

First, the astronauts cleaned the lettuce with special sanitizing wipes(消毒纸巾） and then ate it with some salad dressing.

“It was one small bite for man, one giant leap (飞跃）for ...our journey to Mars.”one astronaut, Scott Kelly, later posted on social media.

Space vegetables are a part of the NASA experiment called “Veg-01”, a study on how plants grow without the effects of Earth’s gravity（重力）. It will allow astronauts to grow and eat their own food during long space explorations.

“If we’re ever going to go to Mars someday, we're going to need a spacecraft that is much more self-sustainable in its food supply(供应）”, said Kelly.

Growing fresh plants on a spacecraft may also provide oxygen and help keep astronauts alive, NASA said.

Veg-o1 started in May 2014.The first batch(一批）of vegetables took 33 days to grow in space before they were taken back to Earth for a safety check. After making sure they were safe to eat, astronauts planted a second batch on July 8. They let the plant grow for another 33 days and were then able to eat it.

Astronauts usually only get vegetables when a supply ship comes to the ISS. Now with vegetables grown in space, they can eat them whenever they want.

【1】Astronauts made history by________.

A.working on the ISSB.eating space-grown lettuce

C.cooking real food in spaceD.building a small greenhouse.

【2】What is Veg-01?

A.It is the name of the greenhouse on the ISS.

B.It is a NASA project for exploring Mars.

C.It is a NASA experiment growing plants in space.

D.It s a NASA experiment on providing oxygen in space.

【3】According to Kelly, why is growing fresh plants in space important?

A.Because it provides people with healthier food.

B.Because it can help astronauts with their journey to Mars.

C.Because it provides astronauts with enough oxygen.

D.Because it cuts the cost of delivering food to the ISS.

【4】What does the underlined word “self-sustainable” mean in Chinese?

A.独自生长的B.自我完善的C.自我延续D.自给自足的

【5】What is the main idea of the story?

A.The success of growing vegetables in space.B.What food astronauts eat in space.

C.How astronauts get food in space.D.Astronauts’ work and life on the ISS.

【5】A

【解析】

本文介绍了在国际空间站种植新鲜的蔬菜，不仅可以供宇航员食用，还可以制造氧气，帮助宇航员维持生命。

【1】细节理解题。根据“Astronauts on board the International Space Station (ISS) once made history by taking bites of red romaine lettuce (长叶药昔）. They became the first humans to eat food that was grown entirely in space.”国际空间站（ISS）上的宇航员曾经通过吃红罗马生菜创造了历史。他们成为第一个吃完全在太空中生长的食物的人类。可知，宇航员吃红罗马生菜创造了历史。故选B。

【2】细节理解题。根据“Space vegetables are a part of the NASA experiment called “Veg-01”, a study on how plants grow without the effects of Earth’s gravity（重力）.”太空蔬菜是美国航天局实验“Veg-01”的一部分，该实验研究植物在不受地球引力影响的情况下如何生长。可知，“Veg-01”是美国宇航局在太空种植植物的实验。故选C。

【3】细节理解题。根据“‘If we’re ever going to go to Mars someday, we're going to need a spacecraft that is much more self-sustainable in its food supply(供应）’, said Kelly.”凯利说：“如果有一天我们要去火星，我们就需要一个在食物供应方面更能自我维持的航天器”。可知，在太空中种植新鲜植物很重要是因为它可以帮助宇航员进行火星之旅。故选B。

【4】词义猜测题。根据上文“If we’re ever going to go to Mars someday,”如果有一天我们要去火星。以及后面的“in its food supply”在食物供应方面，可知，self-sustainable应该是“自给自足的”的意思。此处是指如果有一天我们要去火星，我们就需要一个在食物供应方面更能自给自足的航天器。这是太空蔬菜实验的目的。故选D。

【5】主旨大意题。本文介绍了在国际空间站种植新鲜的蔬菜，不仅可以供宇航员食用，还可以制造氧气。可知，太空蔬菜种植成功了。故选A。

本题的第4小题是词义猜测题。词义猜测题是阅读理解中常见的一种题型，所猜测词汇可以是生词，也可以是熟词新义，还可以是人称代词的指代内容。词义猜测题主要考查考生根据上下文推测词义和语义的能力，突出考查对语境的分析和把握能力。本题可以利用上下文语境来猜测词意。猜测任何词义都离不开上下文，所以要借助上下文对需要猜测的词或短语进行合乎逻辑的推测。
