Another interesting characteristic of bat flight is the way in which bats landupside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force。 Being able to land safely is a critically important skill for all flying animals. Comparatively speaking, ground living animals face no particular challenge when they need to stop running or crawling, while flying animals move at much higher speed, and they must be careful about how they land. Hitting the ground, or even water, at full flight speed would be quite dangerous. Before touching down, they must decrease their speed in order to land safely. Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。發(fā)表在《科學(xué)進(jìn)展》(Science Advances)雜志上的這項(xiàng)新研究將蜜蜂也列入了這一名單。 （4）考查主旨大意。可知，新研究的發(fā)現(xiàn)說(shuō)明了在更多的物種中發(fā)現(xiàn)了數(shù)字認(rèn)知。根據(jù)倒數(shù)第二段中的“Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems.

The new research, published in Science Advances, adds bees to that list.（1）What have the researchers from RMIT University discovered? A.t require a massive brain, there might also be new ways for us to include interactions of both longterm rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer. The findings suggest that advanced numerical cognition (認(rèn)知) may be found much more widely in nature among nonhuman animals than previously suspected. RMIT39。 Researchers have found bees can do basic mathematics, in a discovery that deepens our understanding of the relationship between brain size and brain power. Recently, A study conducted by researchers from RMIT University in Melbourne, Australia showed that bees could perform arithmetic operations like addition and subtraction (減法). 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和推理判斷三個(gè)題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，從而選出正確答案?？芍爻沧搴⒆蝇F(xiàn)象的副作用是在少數(shù)情況下，緊張情緒會(huì)導(dǎo)致父母和孩子之間偶爾發(fā)生爭(zhēng)吵。根據(jù)倒數(shù)第二段中的‘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”可知對(duì)于實(shí)現(xiàn)不同層面獨(dú)立前景的日常緊張情緒，是大多數(shù)家長(zhǎng)和略多于一半畢業(yè)生經(jīng)歷的特征。由此推斷出，孩子們很難找到一份滿意的工作，故選C。 （4）考查推理判斷。 financial and emotional support.”參與這項(xiàng)研究的年輕人對(duì)于搬回家“比預(yù)期的更積極”——他們的羞愧感減少了，因?yàn)樗麄兊脑S多朋友都處于同樣的處境，而且他們承認(rèn)父母在經(jīng)濟(jì)和情感上的支持是有好處的。 （3）考查細(xì)節(jié)理解。即可推理劃線部分單詞trigger意為“導(dǎo)致，致使”，與cause意義一致。根據(jù)第二段中的“The findings disagree with the research published earlier this year showing that returning adult children trigger a significant worsening in their parents39。可知，以往的研究顯示，返鄉(xiāng)的成年子女會(huì)導(dǎo)致父母的生活質(zhì)量和幸福感比之前更差，故選C。根據(jù)第二段中的“The findings disagree with the research published earlier this year showing that returning adult children trigger a significant worsening in their parents39。父母和孩子對(duì)于獨(dú)立的緊張情緒會(huì)導(dǎo)致父母和子女之間偶爾的爭(zhēng)吵。There are occasional quarrels between parents and children.【答案】 （1）C（2）A（3）B（4）C（5）D 【解析】【分析】本文是一篇說(shuō)明文，一項(xiàng)研究發(fā)現(xiàn)，“回巢族”子女在大學(xué)畢業(yè)后回到父母身邊生活對(duì)家庭是有好處的，他們會(huì)與父母建立更親密、更具支持性的關(guān)系，并增進(jìn)兩代人之間的聯(lián)系。Neither parents nor children want to do the chores at home.C.There is more house work needed to be done by the children.（5）What is the side effect of the boomerang children phenomenon?

A.The parents39。The parents were looking forward to their children39。 Areas of disagreement included chores, money and social life. While parents were keen to help, they also wanted different relationships from those they had with their own parents, and continuing to support their adult children allowed them to remain close.（1）What is the finding of the previous research? A. The families featured in the study were middleclass and tended to view the achievement of adult independence for their children as a family project. Parents accepted that their children required support as university students and then as graduates returning home, as they tried to find jobs paying enough to enable them to move out and get on the housing ladder. financial and emotiona
