"That's awesome”, said NASA astronaut Kjell Lindgren, after he ate a piece of red lettuce （萬苣）that was grown in a special box. "Tastes good," agreed US astronaut Scott Kelly, who is spending one year at the research station. "kind of like arugula （芝麻菜），” Kelly added, and then used small bottles to spread olive oil and vinegar on his leaf, much as one might spread ketchup on a hot dog.
NASA says that if space explorers can grow their own food while they are away from the Earth they would be more likely to survive the deep space exploration, which can last months or even years. With no way to resupply a spacecraft making a long journey to and from Mars, the ability to grow food during the trip will be key to survive. "Having the ability for us to grow our own food is a big step in that direction.” Kelly said.
Ray Wheeler, NASA's lead scientist for advanced life support activities at Kennedy Space Center in Florida, also said fresh foods that contain antioxidants, such as tomatoes, blueberries and red lettuce, “could have a positive impact on people's moods and also could provide some protection against radiation in space.”
The red romaine lettuce was grown in a special plant-growing box called a Veggie unit, and was flown to space. The seeds are contained in rooting pillows, which come complete with soil and fertilizer. Since water cannot be poured in space, a special irrigation system delivers moisture to the plant pillows from below.
The seeds were "activated" by Kelly on July 8 and grew for 33 days. On Monday, Lindgren used tongs （夹子）to harvest the lettuce from its growing box, before attaching the leaves carefully to a tray. He cleaned them with food-safe bag and shared with other four members.
A previous crop of lettuce was grown in space last year but was not eaten by astronauts. Instead, it underwent-and passed-food safety tests back on Earth.

A. The journey to and from Mars. B. The way to grow food.
C. The building of a research station. D. The ability of flying in space.
9. Which of the following may Ray Wheeler agree to?
A. The lettuce is a great step enabling human to travel to Mars.
B. Humans won't be able to arrive at Mars without the lettuce.
C. Tomatoes are obviously better than blueberries in size.
D. Radiation wouldn,t be harmful if people ate some lettuce.
10. What is difficult in growing lettuce in space?
A. There is no enough growing area. B. It is very hard to send up the seeds.

【解析】
【分析】本文是说明文。生活在国际空间站内的字航员们日前首次品尝了他们在太空种植出来的生菜。科学家们把这一口舌尖上的味道看作是载人飞船前往火星及其他星球迈出的重要一步。
【7题详解】
细节理解题。根据第一段中的“and then used small bottles to spread olive oil and vinegar on his leaf, much as one might spread ketchup on a hot dog.(然后用小瓶子把橄榄油和醋撒在叶子上，就像把番茄酱撒在热狗身上一样)”可知，斯科特往叶子上撒了橄榄油。故选D项。
【8题详解】
词义猜测题。根据上文“With no way to resupply a spacecraft making a long journey to and from Mars, the ability to grow food during the trip will be key to survive. (由于没有办法为往返火星的长途飞船提供补给，在旅行中种植食物的能力将是生存的关键。)”结合划线句“Having the ability for us to grow our own food is a big step in that direction.( 我们有能力自己种植食物是朝着这个方向迈出的一大步)”可推断，“那个方向” 是指到来往火星的旅程。故选A。
【9题详解】
推理判断题。根据第三段中Ray Wheeler说的话“could have a positive impact on people's moods and also could provide some protection against radiation in space(可能会对人们的情绪产生积极的影响，也可以提供一些防止空间辐射的保护)”可推知，Ray Wheeler同意该蔬菜能够对人们的情绪产生积极的影响并且帮助人们抵御来自火星的辐射，是使人们能够去火星旅行的关键一步。故选A。
【10题详解】
推理判断题。根据第四段最后一句“Since water cannot be poured in space, a special irrigation system delivers moisture to the plant pillows from below.( 由于水不能倒入空间，一个特殊的灌溉系统将水分从下面输送到植物头上。)”可推知，在太空给植物浇水是很困难的，需要一种特别的浇灌方法。故选C。
