  二、文法部分

  Passage 1

  online journalism reporters 在互联网环境下要具备更多的能力,比如编辑、整理、写稿还有回复读者feedback的能力,才能发挥出自己的重要价值。互联网信息发达充足,更需要reporters提高自己的采集和编辑信息的水平。

  Passage 2

  有一种叫做canids的母乳动物,小时候参与到一些活动当中会对自身的成长发育有利。但这些activities都不具有aggressive的特点,而且canids会适当降低自己在参与活动时的力量和攻击性,这样既可以跟同伴玩耍、参与社交、又能保证不伤害同伴。研究者还发现了他们在bite对方前会有“bow”这个姿势,还有headshaking,这在郊狼和狗的活动中也能见到。

  Passage 3

  【powerless persuasion】现在美国总统在大选时的dabate作用已经没有之前那么明显,文中给了一个图表,对比几年内大选的投票数增减情况。虽然投票者已经不再觉得dabate是收获票数的有利途径,但dabate对民众来说依然是informative的,还是有一定的优点。

  Passage 4

  目前人们对于一些modern art的接受更普遍,有一个人开设了一个类似weekly exhibition,里面囊括众多作品,招徕各地的旅游人士、艺术爱好者慕名前来观赏,推动了艺术的发展。但也有一定的问题存在,就是要给一些skeptics解释某些作品到底有什么艺术价值。

  试题原文

  

  标题:Lighten up, Sir David. Our wildlife is safe

  作者:By Matt Ridley Sep. 12, 2013, The Times

  原文放送

  1. Publicising his imminent new series about the evolution of animals, Sir David Attenborough said in an interview this week that he thought a reduction in human population during this century is impossible and “we’re lucky to be living when we are, because things are going to get worse”. People will look back in another 100 years “at a world that was less crowded, full of natural wonders, and healthier”. His is a common view and one I used to share. He longs for people to enjoy the open spaces and abundant herds of game that he has been fortunate enough to see. To that end he thinks it vital that there should be fewer of us.

  2. Ever so politely, I would now passionately disagree with the two premises of his argument. It’s actually quite likely, rather than impossible, that population will be falling by the end of this century and it is also quite likely that the people alive then will have lots more wilderness to explore and wildlife to admire than today.

  3. The rate at which world population grows has roughly halved from more than 2 per cent a year in the 1960s to roughly 1 per cent a year now. Even the total number of people added to the annual population has been dropping for nearly 30 years. If those declines continue, they will hit zero in about 2070 — not much more than 50 years from now. In recent decades the birth rate has fallen in every part of the world. Fertility in Bangladesh has fallen from nearly 7 children per woman in the 1960s to just over 2 today; Kenya from 8 to 4.5; Brazil 5.7 to 1.8; Iran 6.8 to 1.9; Ireland 3.9 to 2…

  4. Europe, Asia and Latin America have already gone through this transition and most countries are producing babies at or below replacement rate of 2.2 per woman, at which population stabilises (without immigration). Africa, for so long written off as a special (basket) case, is following suit almost exactly. For this reason alone, I suspect the world population will stop growing and begin to shrink even earlier than 2070 and almost certainly within this century. But even if it does not, there is good reason to reassure Sir David that our great grandchildren will have more wildlife to look at than he has had.

  5. An ingenious study by scientists at Rockefeller University in New York has recently calculated that even with population continuing to grow, and even with people eating more food and especially more meat, we have almost certainly already passed “peak farmland”, because of the rate at which fertilisers are improving yields. (Or we would have done if not for biofuels projects.) We will feed nine or ten billion people in 2070 from a considerably smaller acreage than we need to feed seven billion today.

  6. Land sparing is already occurring on a grand scale. Forest cover is increasing in many parts of the world, from Scotland to Bangladesh. Wildlife populations are booming in Europe (deer, bears, boar, otters), in the polar regions (walrus, seals, penguins, whales) and North America (turkeys, coyotes, bison, geese) and this is happening fastest in the richest countries. According to one recent report, animal populations grew by 6 per cent in Europe, North America and Northern Asia between 1970 and 2012, while shrinking in tropical regions. There is almost a perfect correlation between the severity of conservation problems and poverty, because the richer people get, the less they try to live off the land and compete with nature — the less they seek bushmeat and charcoal from the forest.

  7. Once again, Africa may spring a pleasant surprise. Over the past four decades agricultural yields in Africa hardly budged while they doubled or quadrupled in most of Asia. That is almost entirely down to a dearth of fertiliser and it is beginning to change. If African yields were to rise, the acreage devoted to farmland globally would start to fall even faster, releasing more and more land for “re-wilding”. The great herds and flocks that so delight Sir David would reassemble in more and more places. The happy conclusion is that making people better off and making nature better off are not in opposition; they go hand in hand.
