Why d we care abut water n Mars?
Mars is a cld, bleak wasteland, with very thin air that we Earthlings culd never breathe. Hwever, many f the pictures ur telescpes, rbiters, and rvers have sent back shw signs that liquid water might have been n the surface f Mars lng ag. Als, we can see ice caps at the nrth and suth ples.
All these signs f water are very exciting. Why? Because n Earth, almst everywhere there is water, there is life. Whether the water is biling ht r frzen, sme srt f creature seems t thrive in it. Is it the same n ther planets? If water nce flwed n Mars, did life nce thrive there t? Or, maybe there is still water n Mars, nly it has gne undergrund. Culd there be tiny life frms—like bacteria—n Mars even nw?
Why d we want t find life n Mars?
NASA's Mars Explratin Prgram is abut "Fllwing the Water." Even if we d nt find life n Mars, if there is water, perhaps smeday Mars culd be inhabited by us!
We have knwn a lt abut the reasns we explre the universe.But have yu ever thught that it is a waste?

Read the text and answer the questins.
Why are sme peple against space explratin?What has space explratin dne fr fd prductin?
Because they think that it is a waste f mney and time. And they argue that we shuld find immediate slutins t help us directly.
The satellites recrd data n land and weather patterns. After careful analysis f the data, the scientists can prvide useful recmmendatins and advice fr farmers.
3.What d the pictures f Earth frm space make peple realize?4.Hw des space explratin benefit the prducts that peple use nwadays?
Peple realize that ur planet’s resurces are limited.
Advanced technlgy which was first created t meet the requirements fr space explratin, which helps us make high-end prducts.
Let’s study the rganizatin and language features!
Cuntries arund the glbe are spending billins f dllars and lts f time n varius space missins, whether t Mars r ther planets much further away. Sme peple argue that we shuld stp wasting time and mney explring space. Instead, we shuld feed the wrld’s pr and find immediate slutins t ther prblems, such as pllutin and fatal diseases. Hwever, thers feel this is a shallw view much fails t realize hw explring space help us.
Read the first paragraph and underline the different pinins abut space explratin.
Find the three tpic sentences that summarize the writer’s arguments abut space explratin.
Firstly, explring space has already made a difference in the fight against wrld hunger.
Secndly, space explratin has already prmted technlgical imprvements that benefit us all.
Finally, sending astrnauts int space has helped peple t think abut the wrld’s prblems and even t find ways t slve them.
In clsing, explring space prvides the wrld with many different benefits. Therefre, it shuld cntinue s as t prvide new and better slutins t peple’s shrt-term and lng-term prblems.
Underline the sentence that repeats the writer’s pinin in the last paragraph.
