A
Mre than tw thirds f the wrld’s plar bears will be wiped ut by 2050, accrding t a shcking new study. By then, scientists say, glbal warming will have melted 42 percent f the Arctic sea ice. By 2100, nly a very few f these imprtant creatures will be left.
The reprt has been prduced by the US Gelgical Survey. The scientists have publicized their findings in the hpe f influencing US Interir Secretary Dirk Kempthrne, wh has been asked t put plar bears n the US endangered species list.
Plar bears depend n flating sea ice as a platfrm fr hunting seals, which are their main fd. Withut enugh ice, plar bears wuld be frced t g nt the land, where they are killed by hunters, and wuld be unlikely t adapt t the life n the land in time. Experts say few little bears wuld survive and the stress culd make many females unable t get pregnant.
The team f American and Canadian scientists spent six mnths studying bears: n the grund, frm sptter planes and in the lab, using cmputer mdels. Sme team members fear the result is even wrse fr the bears than what their reprt says. They say the Arctic is warming faster than anywhere in the wrld and much faster than their cmputer had been frecasting, Satellite bservatins have shwed that the ice has decreased t an all-time lw.
Hwever, nt everyne in the scientific cmmunity believes that glbal warming is happening n such an alarming scale. Anther investigatin has fund that plar bears are still being hunted by wealthy “sprtsmen” wh want their skins and heads. At least ten internatinal cmpanies ffer bear-hunting trips.
1. What d we knw abut Dirk Kempthrne accrding t the passage?
A. He is an animal scientist.
B. He is a prtectr f animals wrking fr the US gvernment.
C. He was asked t put plar bears n the US endangered species list.
D. He ffered t put plar bears n the endangered species list.
2. Why will plar bears die ut if there is nt enugh sea ice?

B. Because plar bears eat ice when they feel thirsty.
C. Because plar bears will be easily fund by hunters withut ice.
D. Because mst female bears are used t giving birth under ice.
3. After a six-mnth study, sme scientists fear that ________.
A. there is smething wrng with their cmputers
B. plar bears will disappear even faster than they ever expected
C. their cmputer mdels are nt as accurate as they expected
D. glbal warming will destry everything in the Arctic
B
The British are knwn fr their sense f humr. Hwever, it is ften difficult fr freigners t understand their jkes. The main pint t remember is that the British ften use understatement.
Understatement means saying less than yu think r feel. Fr example, if smene gets very wet in a shwer f rain, he might say, “It’s a little damp（潮湿的） utside.” Or, if smene is very implite and shuts at anther persn, smene else might say, “She isn’t exactly friendly.” Understatement is ften used in an unpleasant situatin r t make anther persn lk silly. Understatement plays an imprtant part in British humr.
Anther key t understanding British humr is that the British like t make fun f themselves as well as thers. They ften laugh abut the silly and unpleasant things that happen t ur everyday life when smene accidently falls ver in the street. They als like t make jkes abut peple frm different classes f sciety. They like t make jkes abut their accents, the way they dress and the way they behave. What’s mre, the British lve t watch cmedies（喜剧） abut peple wh d nt knw hw t behave in sciety. The cmedies series Mr. Bean is a gd example f this kind f humr.
Mr. Bean is the character created by British actr Rwan Atkinsn in 1990. Mr. Bean desn’t talk ften, and instead he uses his bdy mvement and facial expressins t make peple laugh. Perhaps what makes Mr. Bean s funny is that he des things that adults in the real wrld cannt d. Mr. Bean is ppular in many cuntries arund the wrld because yu d nt have t speak English t understand the humr. Because f this, many peple have becme familiar with the British sense f humr.
4. Why is it difficult fr freigners t understand British jkes?
A. The British ften enlarge the fact.
B. British jkes are cnnected with many different cultures.
C. British jkes are nt as funny as jkes in ther cuntries.
D. The British try t make ut that smething is less imprtant than it is.
5. The authr explains understatement by ________.
A. describing a prcessB. making cmparisns
C. fllwing time rderD. using examples
6. What can be the best title fr the text?
A. British Humr in CmedyB. Humr in Different Cultures
C. Understanding British HumrD. Develping Yur Sense f Humr
C
Where d the turtles g?
Every summer, thusands f endangered green sea turtles climb nt beaches arund the wrld. Each mther sea turtle prduces 100 r mre eggs in a hle, and cvers the hle with sand befre she swims away.
Tw mnths later, the eggs hatch, and the baby turtles climb ut f the sand and swim int the cean. They dn’t reappear until they have grwn as large as dinner plates. Until nw, n ne knws where the baby turtles g r what they d.
“If we dn’t knw where these little turtles are, we can’t prtect them,” says Kim Reich, wh helps slve part f the mystery.
Her teacher, Karen Bjrndal, has studied green sea turtles fr mre than 30 years. Every year, Bjrndal ges t the Bahamas Islands. Many yung sea turtles cme here t live and eat at the end f their childhd.
These turtles are the nly sea turtles that live as plant eaters. In fact, their name may be a result f what they eat. The turtles dn’t lk green but they d have green fat. Scientists learned that the turtles eat green sea plants, which may turn their fat green.
Between 2002 and 2004, Bjrndal caught 44 green sea turtles in the Bahamas. After testing them, she fund smething t supprt the 20-year-ld idea: baby green sea turtles eat meat befre they turn t a diet f plants. In fact, they eat animals that live in the pen cean.
Scientists still need t find where exactly green sea turtles grw. We nw knw that baby green sea turtles are ut in the pen cean, but the pen cean is a big place.
“It is really a prblem,” says Bjrndal. The discvery may help us d a better jb f prtecting this sea animal.
7. What can we learn frm the first tw paragraphs?
A. Baby turtles g t the cean when they are three mnths ld.
B. Mther turtles leave the eggs alne after they prduce them.
C. N ne knws when turtles appear n the beach.
D. Mther turtles are as large as dinner plates.
