Question

【题目】阅读短文, 然后用短文括号中所给词的适当形式填空。
Astronauts used to only have freeze-dried powders and semi-liquid pastes（冻干粉和半液状的糊糊）for meals. Now US scientists want to grow vegetables in mini-greenhouses on the Moon. They look forward to(provide) astronauts or space travelers with fine dinners of fresh vegetables in the future.
Paragon, a company that works with NASA, has designed the "Lunar Oasis（月亮绿洲）".
"Lunar Oasis" is a small greenhouse. It looks like a bell jar put into a 46cm-tall frame. The frame is designed to protect plants while they grow on the Moon.
They plan to send the small greenhouse into space (successful) in 2020. Scientists will put brassica（芸苔）seeds —like acabbage —in the greenhouse. Because this kind of vegetable goes from seed to flower in just 14 days, it can complete (it) life cycle in just one night on the Moon.
The Moon greenhouse has been compared to an experiment at the South Pole. The South Pole greenhouse, now in its(five) year, allows workers living in the coldest place on Earth to have (tomato), lettuces, strawberries and herbs.
"Living on the Moon seems so far away, but it is (importance) that we do this research now," said Jane Poynter, the president of Paragon.

Answer 1

【答案】providing；successfully；its；fifth；tomatoes；important
【解析】(1)look forward to doing sth盼望做某事，to为介词，后跟动词-ing形式，故填providing。
（2）句意：他们计划在2020把一个小的温室成功地送进太空。修饰动词用副词，故填successfully。
（3）名词前用形容词性物主代词，故填its。
（4）year是单数，可知在第五年，所以用序数词，故填fifth。
（5）根据后面几个名词的形式可知这里需要用tomato的复数，故用tomatoes。
（6）句型：it is +形容词+that从句，所以把名词importance变成形容词important。
