Fr the first time, a rat has wn a British aid grup's tp award fr animal bravery. The animal is being hnred fr its wrk searching ut unexplded landmines (地雷) in Cambdia.
Magawa was brn in Tanzania in 2014, and he's a little bigger than nrmal rats. Magawa and several ther rats are part f the “Her Rat” prgram run by a grup called APOPO. Because the rats are s light, there's little danger that they will cause accidents while wrking.
Frm a yung age he was trained t sniff ut TNT (炸药). The training nrmally takes abut a year. Magawa's main jb is t sniff ut a kind f bmb, knwn as a landmine which is hidden, usually undergrund. In Cambdia, where Magawa wrks, landmines were cmmn during lng perids f civil war. Since 1979, these mines have killed r injured ver 64，000 peple.
Magawa is taken ut t a minefield, which he carefully ges ver, sectin by sectin. Magawa's master, Malen, guides him carefully acrss the field n a leash (皮带). When Magawa finds a landmine, he scratches at the dirt abve it, wigwagging that he's fund smething.
Because the rats wrk by sniffing, they're very fast. It nly takes Magawa 30 minutes t search an area as big as a tennis curt. A human ding the same jb wuld take fur days. Malen says that Magawa and his clleagues are very cnfident in the field. He wrks quickly and is easily able t make decisins abut whether smething is a danger r nt. Magawa is the star sniffer f the “Her Rat” prgram. He's fund 39 landmines and 28 bmbs that were drpped frm planes, but never explded.
1．What made Magawa jin in the “Her Rat” prgram?
A．His beneficial birthplace.
B．His great achievements.
C．His strict training.
D．His being light in weight.
2．What des the underlined wrd “wigwagging” mean in Paragraph 4?
A．Signaling. B．Pretending.
C．Remembering. D．Accepting.
3．What can be inferred abut Magawa when he is wrking?
A．He finds a minefield ineffectively.
B．He makes accurate judgments.
C．He has ther rats act cnfidently.
D．He spends mst f his time digging dirt.
4．Where is the text prbably taken frm?
A．A textbk. B．A nvel.
C．A newspaper. D．A diary.

As we all knw, mst animals nly perfrm tricks when given treats. Hwever, Kim, the wrld's first spider t learn a skill, needs n stimulus (刺激) t d what she lves—jumping t different heights and distances—upn the instructin f a team f scientists frm the University f Manchester.
While the idea f training a spider might sund evil, the researchers' mtives were purely scientific. They are trying t unlck the secrets behind the jumping spiders' extrardinarily high leaps t catch prey (猎物) r t escape their enemies. A better understanding f the spiders' leaps wuld help experts develp mre efficient flying and jumping rbts.
The scientists fund that Kim culd gather enugh frce in her legs t jump mre than six times the length f her wn bdy frm a statinary psitin. What was even mre amazing was that she always landed perfectly. Fr shrter distances, Kim used a lt f energy, resulting in quick leaps, which the researchers believe prbably increases her chances f catching fast­mving prey. The farther the distance was, the less extra energy was used, resulting in slwer but precise leaps.
Previus studies have indicated that spiders use bth their muscles and hydraulic (液压的) pressure—a mechanism by which bld is transferred t their extended legs—t make them push ff the grund. Hwever, in Kim's case, her leg muscles alne appeared t be generating enugh frce fr the lift­ff. The researchers nw intend t d further research t cmprehend fully nt just the spiders' jumping technique, but that f ther insects as well. “We are familiar with rbts that are aimed at taking ver human functins, but there are millins f insects in the wrld that perfrm specific functins that we have interest in and can be adapted fr rbtics，” says Nabawy, the leading engineer f the researching team.
5．What is the purpse f scientists' researching the jumping spiders?
A．T have fun and relax.
B．T help develp rbts.
C．T get rid f spiders.
D．T prtect this species.
6．Why did Kim use a lt f energy fr shrt leaps?
A．T jump high enugh.
B．T land mre precisely.
C．T catch fast­mving prey.
D．T increase chances f escape.
7．What des the underlined wrd “that” in the last paragraph refer t?
A．Jumping technique.
B．Leg muscles.
C．Further research.
D．Energy fr lift­ff.
8．What can be a suitable title fr this passage?
A．Jumping Techniques Used by Jumping Spiders
B．Jumping Spiders Inspired Develping Rbts
C．Animals Perfrm Tricks if Prvided With Treats
D．The Wrld's First Spider That Jumps n Demand
