Astronauts may soon be going to the moon again. NASA plans to build bases (基地 ) there.{#blank#}1{#/blank#}So they may have to grow some of it on lunar(月球的) farms. But can plants grow on the moon? Maybe it is possible. {#blank#}2{#/blank#}The study showed that plants can successfully sprout(发芽) and grow in lunar soil (土壤). It also turned out that success
could depend on where on the moon you do your planting.
In the new study, scientists used the soil that astronauts collected from the moon before to grow plants here on Earth. They put this soil in little cups. {#blank#}3{#/blank#}Other cups got Earth soil. Then the scientists planted seeds and watered the soil.
In the Earth soil, plants sprouted healthy leaves. The lunar soil sprouted leaves, too.{#blank#}4{#/blank#}The older the lunar soil was, the worse the plants seemed to grow.
Stephen Elardo, one of the scientists, says it still might be possible to grow plants on the moon.
{#blank#}5{#/blank#}One example may be where volcanoes (火山) once erupted (爆发). The soil is newer there. Scientists still have much to learn, but this study brings humans one step closer to calling the moon home.
A. The key could be finding the right place. B. But those plants were smaller and less healthy. C. Some cups got lunar soil. D. Astronauts won't be able to take all the food they will need. E. Astronauts plan to plant different plants on the moon. F. That's according to a new study from University of Florida scientists. |
