三、完形填空（每小题1分，满分10分）
Today was an exciting day aboard the International Space Station.
After cleaning myself, I ate breakfast with Clark. We had to be very 31 with our food so it wouldn't float away. Suddenly, a warning light started flashing on the control panel. The computer showed there was a 32 with the oxygen system.
My heart beat 33 when I saw the message. Clark checked the computers while I looked at the oxygen tanks. We discovered a small leak in one of the pipes. This was 34 because we need oxygen to breathe.
"Don't worry,"Clark told me. "We can 35 this."
I remembered my training back on Earth. We prepared our tools and put on special safety equipment. Working in space is 36 because everything wants to float away. I had to hold on to the wall with one hand while using tools with the other hand.
Carefully, I placed a special patch over the leaking 37. I had to press the patch hard with both hands and count to sixty to make sure it stuck properly. My arms started to feel tired, but I didn't let go. We waited 38 for a few minutes while the computer checked the repair. Finally, the warning light 39! The oxygen level was returning to normal.
I felt proud that we had solved the problem and made our space station 40 again. It's wonderful to know that we can handle emergencies when they happen in space.

32. A. problem B. fight C. game D. sense
