But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities. However, the study says, daytoday tensions about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict, characterised the experience of a majority of parents and a little over half the graduates.Boomerang children made their parents happier.B.s return.C. quality of life became worse than before.D.causeB.ariseD.They are ashamed of turning to their parents for help.B.They are doubtful about whether they should return.D.The children want to keep in closer touch with their parents.B.It is harder for the children to secure a satisfying job.D.Both parents and children enjoy a more harmonious relationship.B.Not only parents but also children want to be independent.D.而這一發(fā)現(xiàn)與今年早些時(shí)候發(fā)表的一項(xiàng)研究結(jié)果相矛盾，該研究顯示，返鄉(xiāng)的成年子女會(huì)導(dǎo)致父母的生活質(zhì)量和幸福感顯著下降。 （1）考查推理判斷。 quality of life and wellbeing.”這一發(fā)現(xiàn)與今年早些時(shí)候發(fā)表的一項(xiàng)研究結(jié)果不一致，早些的研究顯示，返鄉(xiāng)的成年子女會(huì)導(dǎo)致父母的生活質(zhì)量和幸福感顯著惡化。 （2）考查詞義猜測(cè)。 quality of life and wellbeing. ”通過(guò)新舊研究對(duì)比，以往的研究表明，返鄉(xiāng)的成年子女會(huì)導(dǎo)致父母的生活質(zhì)量和幸福感顯著下降。故選A。根據(jù)第三段中的“The young adults taking part in the study were‘more positive than might have been expected’about moving back home – the shame is reduced as so many of their friends are in the same position, and they acknowledged the benefits of their parents39。）可知，大學(xué)畢業(yè)生對(duì)回家的態(tài)度是積極的，很高興能夠回家，故選B。根據(jù)第四段中的“But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.”但他們承認(rèn)，如今的畢業(yè)生情況有所不同，他們畢業(yè)時(shí)背負(fù)著巨額債務(wù)，工作機(jī)會(huì)也更少。 （5）考查細(xì)節(jié)理解。在少數(shù)極端情況下，這種緊張情緒接近沖突。故選D。4．犇犇閱讀理解 Research suggested that WiFi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天線(xiàn))that could be fitted in existing WiFi networks. When it was tested on a backpack, the accuracy rate topped 95 percent. But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools, the team said, noting its design can inspect bags or luggage without being an exposure to privacy.s a growing need for that now.

Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.”檢查行李總是需要人力，我們希望開(kāi)發(fā)一種互補(bǔ)的方法來(lái)減少人力，可推知選A。根據(jù)最后一段中的“Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes”今后的工作將繼續(xù)側(cè)重于提高識(shí)別物體和成像形狀及體積的準(zhǔn)確性，故選B。5．犇犇閱讀理解 s head has always been something of a puzzle. Dr Steven Brown, from McMaster University in Canada, said, It looks like when you are acting, you are suppressing (壓制) yourself。 Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments. Each actor was asked to respond to different questions, based on two different premises (前提). In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet
