【正文】 main stress hormone. It increases sugar in the bloodstream. If you are truly in danger, these hormones can help you. They are part of what we call our fightorflight response. Dr. Chockalingam, a heart disease specialist in Columbia, advises his patients to smile. He says a smile may be one way to help your heart. When we smile, the brain wiring changes. The chemicals that are released are more positive. He says smiling is the first step in fighting physical and emotional stress and its sometimes harmful effects on human health. This is not just New Age advice. Several studies support his opinion. 5．閱讀理解 performance ”可知，機(jī)器人目前還在華盛頓州立大學(xué)的智能屋里進(jìn)行測(cè)試，故選B?？v觀(guān)全文可知，本文介紹了一款由美國(guó)華盛頓州立大學(xué)的科學(xué)家們研發(fā)的機(jī)器人。根據(jù)最后一段中的“ While we are still in an early stage of development, our initial results with RAS have been promising”可知，Minor對(duì)這款機(jī)器人的未來(lái)發(fā)展充滿(mǎn)信心、非常樂(lè)觀(guān)，故選C。 performance…”可知，這臺(tái)機(jī)器人的表現(xiàn)還要經(jīng)過(guò)進(jìn)一步的測(cè)，說(shuō)明正在測(cè)試階段，故選B。 （2）考查推理判斷。 （1）考查細(xì)節(jié)理解。D.RAS, the first robot to make home smart.B.Uncertain.（4）What can be a suitable title for the text?

A. RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently. The Robot Activity Support System or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.RAS bines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected, said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.4．閱讀理解 故選A。根據(jù)最后一段中的“By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help.”可知Richard認(rèn)為通過(guò)使用這些大數(shù)據(jù)方法，我們可以將我們的注意力轉(zhuǎn)向現(xiàn)代保護(hù)中的難題:哪些物種和地區(qū)正在發(fā)生變化，哪些人最關(guān)心這些問(wèn)題，哪些人能夠提供最多的幫助。故選C。根據(jù)倒數(shù)第二段中的“it was really exciting and quite unexpected for me to see people39。故選B。根據(jù)第三段中的“Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.”可知在維基百科上，許多動(dòng)植物的行為似乎都有季節(jié)性趨勢(shì)。故選D。 （1）考查細(xì)節(jié)理解。這一發(fā)現(xiàn)提出了監(jiān)測(cè)世界生物多樣性變化的新方法。 work. pushes people to solve difficult problems.【答案】 （1）D（2）B（3）C（4）A 【解析】【分析】本文是一篇說(shuō)明文，牛津大學(xué)的一個(gè)國(guó)際研究小組發(fā)現(xiàn)，人們使用互聯(lián)網(wǎng)的方式與自然界的季節(jié)性運(yùn)動(dòng)密切相關(guān)。s care about nature. about people39。 heavy work load.（3）How does Mittermeier feel about the search results? with Wikipedia39。s Wikipedia interest closely related to changes in nature.s a concern among conservationists (生態(tài)環(huán)境保護(hù)者) that people are losing touch with the natural world and that they39。s biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation. And not just birds. Mittermeier and his team surveyed nearly billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals. An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in the natural world. Their online species searches follow the patterns of seasonal animal migrations (遷徙).3．犇犇閱讀下面文章，然后從題中所給的A、B、C、D四個(gè)選項(xiàng)中，選出每個(gè)問(wèn)題的最佳選項(xiàng)。故選A。根據(jù)第一段“Gardeners such as Prince Charles who claim that talking to plants encourages them to grow have long been seen as a little silly. But scientists have discovered evidence which suggests the Royal may actually be right and they could be listening to him. Biologists at Tel Aviv University in Israel have found that flowers can act as a plant39。故選D。根據(jù)第四段中的“But the study, published on the openscience website BioRxiv, suggests the efforts of gardeners who talk to their plants may not be in vain.”研究表明，園丁們和他們的植物交談的努力可能不會(huì)白費(fèi)。故選C。s ability to respond to pollinators may be weakened in city environments or beside a busy road. ”哈達(dá)尼教授認(rèn)為，植物對(duì)傳粉者做出反應(yīng)的能力可能會(huì)在城市環(huán)境或繁忙道路旁減弱。 （2）考查推理判斷。根據(jù)第二段中的“When the researchers played recordings of flying bees to evening primrose flowers, within three minutes the sugar concentrations in the nectar (花蜜) of its flowers increased.”可知，蜜蜂飛到夜來(lái)香花，在三分鐘內(nèi)其花朵花蜜的糖的濃度會(huì)增加，所以花蜜會(huì)更甜。 growth.【答案】 （1）B（2）C（3）D（4）A 【解析】【分析】本文是一篇說(shuō)明文，介紹了人與植物的交流可以促其生長(zhǎng)。Women39。t grow without sound.Bees are best pollinators.C.Plants gardeners talk to frequently develop well.（4）What does the text mainly talk about?
