5.When Jack Homer is on the job,he lives in a tent.And he hunts from sunup to sundown across the plains of Montana.
"When I'm walking around the field looking for things,I run across snakes and,occasionally,grizzly bears,"Homer says.Horner is curator of paleontology (古生物學)at the Museum of the Rockies in Bozeman,Montana.(71)D
Horner finds dinosaurs in the forms of fossilized bones.He uses these bones to help scientists understand how dinosaurs lived when they ruled the earth more than 65million years ago.
(72)C To locate a good spot to hunt for them.Horner uses a geologic map"I just look up the geologic age in which dinosaurs lived,"Horner says."I look on the map to see where that rock is exposed at the surface of the ground.And then I walk I around in those areas looking for bones."(73)B They dig out the bones using tools as big as jackhammers and as small as dental picks.Then they take the bones,wrapped in plaster casts for protection,back to the museum.
Horner is so good at finding and interpreting dinosaur bones that he is considered one of the leading paleontologists in the world.In 1978,he discovered the first nest of baby dinosaurs ever found.The nest was the first evidence that Dinosaurs cared for their young.(74)G Paleontologists got to know how dinosaurs laid their eggs and how they took care of their young.Paleontologists learned all sorts of things that people hadn't even guessed at before.
Horner says some people think his job very romantic and assume that he is a daring adventurer.(75)A"Getting the stuff out of the ground when it's snowing or blowing 40miles an hour can be miserable.Of course,it can get to be 110degrees with no shade too."But Horner also admits that he wouldn't be a dinosaur hunter if it were not exciting.
A.Actually,the job is mostly hard work.
B.Later,trained workers go to the"dig"site.
C.Dinosaur bones are usually buried in rock.
D.Or,to put it another way,he is a dinosaur hunter.
E.I construct the evidence the same way as a detective does.
F.He also takes a lot of notes and photographs to record what he has found.
G.Horner's discovery put paleontologists into a new area of understanding dinosaur behavior.
分析 本文是一篇科普類文章閱讀.描述了一位古生物館長荷馬,他是一位恐龍搜尋者.通過研究恐龍的化石骨骼來了解他們的習性.荷馬的工作也頗具浪漫,但也是異常辛苦.
解答 DCBGA
71.D.本題考查前后句子的聯系,根據開頭When I'm walking around the field looking for things,和Horner is curator of paleontology 可知,后面進一步描述他確切的身份是一個恐龍搜尋者;故選D.
72.C.本題考查前后句子的聯系,根據后面的句子To locate a good spot to hunt for them.Horner uses a geologic map可知,這句主要是講解的恐龍骨的埋藏 地點;故選C.
73.B.本題考查前后句子的聯系,前面提到 I walk I around in those areas looking for bones,后面又描述They dig out the bones using tools可知,尋找到骨頭后自然會有人挖掘;故選B.
73.G.本題考查前后句子的聯系,前面提到The nest was the first evidence that Dinosaurs cared for their young該巢穴提供了第一份恐龍會養育后代的證據.可知,接下來就開始荷馬的發現的意義;故選G(荷馬的發現引導古生物學家進入對恐龍行為理解的全新領域.).
75.A.本題考查前后句子的聯系,通過后面一句Getting the stuff out of the ground when it's snowing or blowing 40miles an hour can be miserable.可知,這是描述他們工作的辛苦;故選A.
