Question

BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity(重力).
However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show, because it's impossible to cry in zero gravity.
Of course, astronauts can still produce tears. But crying is much more difficult in space, according to The Atlantic(大西洋月刊) in January. Without gravity, tears don't flow(流動) down out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go-they just stick(粘) to your eyes.
In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eyes...They just kind of stay there."
Besides making your vision(視線)unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is stinging(刺痛) like crazy," Feustel told his teammate during the walk.
Since gravity doesn't work in space, astronauts need some extra help to get rid of（除去） the tears. Feustel chose to rub his eyes against his helmet to wipe(擦) the tears away. Another choice is to just wait-"When the tears get big enough they simply break free of the eyes and float around," astronaut Ron Parise told The Atlantic.
There are lots of small things-things like crying-that we are so used to on Earth. We usually take them for granted until they become a problem in a totally different environment, like space.  There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up（嘔吐）everything in their stomach, according to the UK National Space Center.
Therefore, perhaps it's only space explorers who can honestly say: "Gravity, you're the best."

D．They float around and cause trouble.

小題3:The underlined phrase "take them for granted" in paragraph 7 means _______.

A．find them important

B．consider them useless

C．need them during an emergency

D．fail to notice their presence(存在)

小題4:The second-to-last paragraph (paragraph 7) is mainly about_______.

A．suggestions of how astronauts can stay comfortable in space

B．other basic things that are difficult to do in space

Answer 1

小題1:D
小題2:A
小題3:D
小題4:B

試題分析：這篇文章講述了在太空失重的情況下，很多在地球上很平常的事情，像流眼淚，吃飯，在太空中是很難做的。
小題1:細節題。根據文章第二段，第三段Without gravity, tears don't flow(流動) down out of the eyes like they do here on Earth.可知，在太空中沒有重力，眼淚是不能從眼睛中流下來。故選D
小題2:細節題。根據文章Besides making your vision(視線)unclear, this can also cause physical pain.可知，在太空中，眼淚不僅使視線模糊，也可以引起身體的疼痛。故選A
小題3:推斷題。根據文章We usually take them for granted until they become a problem in a totally different environment, like space.可知，人們通常把眼淚視為理所當然的，知道它在完全的不用的環境中成為了一種問題，比如在太空中。所以，take them for granted的意思是沒有注意到它的存在。故選D
小題4:細節題。這篇文章第二段到最后一段講述了在地球上很平常的一些事情，在太空中卻很難做的。故選B
點評：此類題目較簡單，重在理解全文所講的內容，題目多以細節題，圍繞太空失重的情況下，很多在地球上很平常的事情變的難以實現進行闡述，在答題時注意結合題目找到文章中找到相對應的出處，仔細的對比，快速定位。
