（2020 . 天津市第一中学高一月考）Next mnth, I’m traveling t a remte area f central Africa and my aim is t knw enugh Lingala ne f the lcal languages-t have a cnversatin. I wasn’t sure hw I was ging t manage this-until I discvered a way t learn all the vcabulary I'm ging t need.Thanks t Memrise, the applicatin I'm using, it feels just like a game.
“Peple ften stp learning things because they fee they’re nt making prgress r because it all feels like t much hard wrk, ”says Ed Cke, ne f the peple wh creted Memrise. “We’re trying t create a frm f learning experience that is fun and is smething yu’d want t d instead f watching TV.”
Memrise gives yu a few new wrds t learn and these are “seeds” which yu plant in yur “greenhuse” . When yu learn the wrds, yu “water yur plants” . When the applicatin believes that yu’ve really memrized a wrd, it mves the wrd t yur “garden” . And if yu frget t lg n, the applicatin sends yu emails, reminding yu t “water yur plants” .
The applicatin uses tw principles abut learning. The first is that peple memrize things better when they link them t a picture in their mind. Memrise translates wrds int yur wn language, but it als encurages yu t use “mems” Fr example, I memrized mtele, the Lingala wrd fr “engine”, using a mem I created-I imagined an ld engine in a mtel（汽车旅馆）rm.
The secnd principle is that we need t stp after studying wrds and then repeat them again later, leaving time between study sessins. Memrise helps yu with this, because it’s the kind f applicatin yu nly use fr five r ten minutes a day.
I’ve learnt hundreds f Lingala wrds with Memrise. I knw this wn’t make me a fluent speaker, but I hpe I’ll be able t d mre than just smile when I meet peple in Cng. Nw, I need t g and water my Vcabulary!
What des Ed Cke make an effrt t d with Memrise?
A .Create memrable experiences.
B .Make prgress with hard wrk.
C .Learning wrds instead f watching TV.
Cmbine study with entertainment.
5. What are yu ding when yu “water yur plants”?
A. Lgging n t the applicatin.
B. Being a Memrise user.
C. Practising the vcabulary.
D .Mving wrds t yur garden.
6. Hw des Memrise wrk?
A.By linking different mems tgether
B. By putting knwledge int practice
C. By ffering human translatin services
D .By applying an assciative memry apprach.

（2020 . 辽宁鞍山高一月考）Scientists have fund what they believe are pieces f a meter（流星）that fell t Earth earlier this year.The bjects were discvered ff the cast f the United States in the Pacific Ocean near the nrthwestern state f Washingtn.
The crew f the Nautilus recvered the rck particles（颗粒）.The grup says its aim is t examine areas f the cean that have never been explred befre.The search was launched after the U.S. gvernment weather statins bserved a large meterite explding fur mnths ag.The explsin lit up the sky and sent the rck particles falling t Earth, which landed in the pacific.
Marc Fries is with the U.S. space agency，NASA，and he said the meterite fall was the largest recrded ver the United States in at least 20 years. Fries is part f the latest explratin team searching fr meterites. He said he culd nt be happier with the discvery, The Seattle Times reprted. “This has been the experience f a lifetime, ” he added.
The scientists examined what they believe were tw small meterite pieces. Further testing is needed befre they can cn firm that the material came frm the explsin in March.
The Nautilus is equipped with tw remtely perated underwater vehicles（ROVs）, called Hercules and Argus. These rbtic submarines（潜艇）help researchers find and cllect materials frm the seaflr. The Hercules ROV was launched frm the nautilus ship int the Pacific Ocean in the search fr meterite pieces in the cean.
Fries said infrmatin abut the explsin led scientists t think that the explsin was unusually strng.The fact that the particles landed in the cean，instead f n land，means larger pieces may have survived and can be studied Fr this reasn fries tld the Live Science website，scientists decided t launch the “first intentinal search fr meterites frm the cean”. Until the latest research, scientists had nly accidentally discvered a small number f meterites frm drilling peratins.
“The meterite pieces are small, melted pieces f rck,” Fries tld Live Science. He thught the bjects recvered frm the bttm f the sea likely came frm the recent explsin fr tw reasns. Firstly, meterite particles are “basically made f glassy materials that d nt tend t last lng in seawater,” he tld the website. Secndly, Fries said they came frm what lked like a small hle n the seaflr. “It’s sme evidence that they came frm smething that fell.”
The first Nautilus meterite cean missin was t explre and search within a ne-square-kilmeter area. The explratin team expressed high hpes fr future searches. “If successful, this will be the first knwn recvery f a meterite frm the cean,” the grup reprted n its website.
12. Which f the fllwing can be cncluded frm the third and furth paragraphs?
A. Fries takes the lead rle in the latest explratin team.
B. The meterite fall is the largest that has been recrded s far.
C. Scientist’ main task is t explre the unknwn f the Pacific Ocean.
D. It’s unclear whether what scientists fund came frm the March explsin.
13. What des the authr say abut the Nautilus?
A. It is in the pssessin f NASA.
B. It is a research ship with tw ROVs.
C. It is a rbtic submarine wrking underwater.
D. It is mainly designed t recver meterite pieces.
14. What makes the search fr meterite pieces frm the cean an intentinal ne?
A. The pssible presence f larger rck particles.
B. The request frm NASA and the U. S gvernment.
C. The accidental discvery f tw small meterite pieces.
D. The team’s expectatin f an extrardinary achievement.
15. The wrds frm Fries in Paragraph 7 prbably aim at ______.
A. intrducing ways t identify the meterite pieces
B. explaining the features f the meterite piece
C. prving where the meterite pieces came frm
D. revealing hw the meterite pieces were discvered

When she was alive, I had bught anther Beanie Baby but never had the chance t send it t her, s I tk it with me hping that I culd put it in her casket. When I was n the plane, I just culdn’t help thinking abut the time we had spent tgether.
Her funeral was very different frm any funeral I’d ever been t I remembered crying s hard, I felt weak. I thught abut the talks we had when she was in hspital. She was always curius abut my life and ptimistic abut everything she faced thugh she had a rare disease.I recalled her wrds f having a different bdy and i abslutely knew she wuld d better than I culd. I nw knw that I must never take anything fr granted, especially my health and the gift f life.
