Recently, students in ur class have had a heated discussin abut the prblem whether space is wrth explring. Students have different ideas abut it.
30% f the students think that space explratin is nt wrthwhile. They think space is t far away frm us and ur daily life and space explratin is a waste f mney. And the mney spent n space explratin can be used t slve the Earth’s prblems such as starvatin and pllutin.
On the ther hand，70% f the students think that space is wrth explring because we have benefited a lt frm it, such as using satellites fr cmmunicatin and weather frecast. What’s mre，with further space research，we may slve the ppulatin prblem by mving t ther planets ne day. Als，space research will enable us t find new surces t slve the prblem f energy shrtages n Earth.
