三、阅读理解
A biologist from the National Park Service discovered a rare and unusual mammoth(猛犸) skull (颅骨) buried in a 13,000-year-old rock layer on the Santa Rosa Island, the second largest landmass in the Channel Islands, California. The fossil of the extinct giant animal is leaving many paleontologists(古生物学家) scratching their heads. Despite the fact that it's possibly the best preserved mammoth skull ever found and of high scientific importance, the species of the individual it belonged to can't seem to be identified yet—it's too big to be a pygmy(矮小的) mammoth and too small to have come from a Columbian mammoth. Some say it's a new species while others believe the truth lies somewhere in between.
The first mammoths showed up in North America around two million years ago, but it was only during the last two ice ages that the Columbian species, which could grow to be up to 14 feet tall, made its way to the Channel Islands 100 miles west of Los Angeles. Once the ice melted, many populations became trapped on the island and evolved into pygmy mammoths, an endemic species (地方种) to the Channel Islands which grew only to six feet tall.
Judging from its size, the newly found mammoth skull doesn't seem to fit any of the two species, Columbian or pygmy. To make things even more confusing, one of its two tusks(象牙) is nearly five feet long and coiled in a manner that resembles those of fully grown mammoths but the left tusk is shorter and sloped, more like a juvenile(青少年).
This has caused some scientists to say the Santa Rose skull may belong to a transitional species. Whatever the case, a following examination of the mammoth's teeth should put the matter to rest. The analysis will also tell us how old the mammoth was when it died, so we can tell for sure whether it was an adult or a juvenile.
More interesting than the mammoth's lineage, however, might be its story. The giant mammal lived 13, 000 years ago or roughly the same timeline of the "Arlington Man", a 13,000-year-old human skeleton also found on the Santa Rosa Island. Some 3,000 years later humans were already spread throughout the continent and the Channel Islands' mammoth went extinct. The present finding might help reveal a link between the two.
The remains also seem to confirm a long-held assumption that there were two mammoth migrations to the Channel Islands. "The discovery of this mammoth skull increases the probability that there were at least two migrations of Columbian mammoths to the island: during the most recent ice age 10,000 to 30,000 years ago, as well as the previous ice age that occurred about 150,000 years ago," said USGS geologist Dan Muhs.
1.The underlined part in the first paragraph means the paleontologists feel _________.
A.excited B.confused C.anxious D.frustrated
2.Which of the following is NOT among the reasons why the newly found skull is special
A.It is possibly the best preserved mammoth skulls.
B.Its size fits neither the Columbian mammoth nor the pygmy mammoth.
C.It was found on the Santa Rose Island, California.
D.Its two tusks give out different information of the mammoth's age.
3.What can be inferred from the last three paragraphs
A.The examination of the mammoth's teeth can tell us how old it was when it died.
B.There may be a link between the extinction of mammoths and the spread of humans.
C.At least two mammoth groups migrated to the Channel Islands during different periods of time.
D.There remains no final conclusion as to how many mammoth groups migrated to the Channel Islands.
4.This passage mainly tells us the newly found mammoth skull ________.
A.is among the best preserved, but with a mysterious story
B.has aroused a debate over what species it belongs to
C.is of great scientific importance to mankind
D.is likely to confirm a former assumptions
四、阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式。
Despite his father's strong objection, Darwin set off for his adventures on the ship, the Beagle, without completing his degree of ①________. However, it was this journey ②________ led to one of the most important ③________ (science) discoveries of all time.
Darwin was pleased with the chance to study a ④________ (various) of living things naturally. After he ⑤________ (spend) some time in South America, his room on the ship was crowded with samples of plants and animals. He wondered ⑥________ different species came to exist, for people believed that all species had appeared on Earth at the same time.
On the Galápagos Islands, Darwin studied the finches there; he found ⑦________ seemed that their beaks had evolved according to ⑧________ food was available, so he suspected that the finches had evolved from a common ancestor. That was the answer he had been seeking for: new species of plants and animals evolved from ⑨________ (early) ancestors.
Today, On the Origin of Species is regarded as one of the most important works ever ⑩________ (write).
答案以及解析
一、
1.答案：nature
2.答案：ancestors
3.答案：suspect
4.答案：evolution
5.答案：seeds
6.答案：distant
解析：句意:望远镜把许多遥远的星球显现在我们的眼前。用形容词作定语,修饰名词stars。
7.答案：seeds
解析：句意;我们种子比较多,可以匀给你们一些。根据语境可知,此处是复数概念,故用可数名词的复数形式。
8.答案：samples
解析：句意:我们正免费发放2000份样本,如果你感兴趣,可以拿一份。根据前面的数字2000可知,此处是复数概念,故用可数名词的复数形式。
二、答案：1. came to exist
2. in question
3. adapting to
4. dating back to
5. answered the call
6. What's more
三、答案：1-4.BCDA
解析：语篇解读:这是一篇新闻报道。主要讲述的是新发现的猛犸象头骨的事情,古生物学家不能确定它属于哪一类。
1.解析:推理判断题。根据第一段最后两句话可知,古生物学家很难确定新发现的化石为哪一种类的猛犸象,他们因此感到很困惑。故选B项。
2.解析:推理判断题。根据倒数第二段内容可知,在这个地方以前就发现过13 000年前的人类头骨化石,所以C项并不是这次发现的化石的特别之处,其他几项才是它的特别之处。故选C项。
3.解析:推理判断题。根据最后一段第一句话"The remains also seem to confirm a long-held assumption that there were two mammoth migrations to the Channel slands."及第二句话中的"at least two migrations of Columbian mammoths"可知,对于猛犸象究竟有几次迁移并无定论。故选D项。
4.解析:主旨大意题。通读全文可知,本文主要讲述的是最新发现的保存最完好的猛犸象头骨的事情。关于这个头骨,古生物学家也不能确定它究竟属于哪一类。故选A项。
四、答案：medicine ; that ; scientific ; variety; had spent; how ; it ; what ; earlier ; written
