[单项选择] Today, the British fleet no longer dominates the high seas: our share of the world’’s merchant fleet has fallen from 40 per cent to around eight per cent. But, in terms of tonnage, the British merchant navy has continued to expand. It can now carry over two-thirds more than it could in 1914, and, almost alone among our traditional industries, shipping has remained a major success story.
Unlike the rest of British industry, ship-owners invested big. In the early 1960s, the shipping companies made full use of government grants and tax concessions. Between 1966 and 1976, British shipping lines invested at a rate of over ￡ 1 million a day. By the early 1970s, it seemed that, somewhere in the world, a new British ship was being launched every week. The result is that Britain has a very modern fleet: the average age of our merchant ships is only six years, and over half the fleet is under five years old. For some time now, British shipping managers have stayed ahead of the competiti
A. a new ship was being launched every week in the world
B. the average age of British merchant ships is only six years
C. half the British fleet is under four years old
D. most British fleet ships are sophisticated
[不定项选择题]资料：It’s easy to trace the evolution of the automobile.At most，we’re only talking about a few centuries of technological development，and most of the plans，prototypes and models are still around. With just a little research，you can easily trace the latest model electric hybrid back to its steam-powered ancestors.
Your family tree is probably a different matter. Even an extensive genealogy chart can only reach back so far，and mortality puts a rather strict limit on exactly how many “models” are still on the road. Humanity’s evolutionary progression is even more difficult. We still have plenty of living primate relatives，but many of the life forms that connect the evolutionary dots are long extinct.
Evolutionary biologists use several methods to decipher exactly how we came to be as we are.In fact，the field itself encompasses several different disciplines in addition to biology，like genetics，psychology，geology，archaeology linguistics，anthropology and primatology just to name a few. Naturally，paleoanthropology also plays a key role，as we have to turn to the fossil record for many clues about our ancient primate，human and nearly human ancestors.
While the fossil record by its very nature is incomplete，there’s no shortage of fossil evidence to link the planet’s varied life forms into a great tree of life， a chart that scientists call a phylogenetic tree. You can think of humans as the very tip of just one branch on that tree called “hominid.” Chimpanzees exist at the end of an adjoining branch called “panin.” Follow both the hominid and panin branch back about 5.4 million years， and you’ll find a point where scientists think the two converged from a single，common ancestor.
Fossil evidence helps scientists to reconstruct these trees，but so do morphological and genetic studlies. Genetic analysis has yielded striking similarities between chimps and humans. As such， scientists know a last common ancestor of chimps and humans existed，even if we’ve yet to determine the exact species. Yet paleoanthropologists have found numerous hominid fossils to bridge the evolutionary progression from that unknown common ancestor to modern humans. These finds include such famous East African fossils as Lucy（Australopithecus afarensis），which strengthened the importance of bipedalism in human evolution and proved an essential milestone on our way to modern Homo sapiens.
Fossil evidence for human evolution will never be complete，as fossils themselves are rare geologic occurrences.Nevertheless，by incorporating other scientific disciplines，we’re able to build an increasingly accurate picture of just what our evolutionary family tree consisted of.
Which statement is true，based on Para.3?
A.Hominid and panin were humans ancestors 5.4 million years ago.
B.Chimpanzees existed at a branch of phylogenetic tree are called “hominid”.
C.Humans on phylogenetic tree analysis are supposed to be called “panin.”
D.Scientists think humans and Chimpanzees converged from a common ancestor，based on phylogenetic tree analysis.
