【正文】 y memory, winters always used to be really unpleasant. You had to bundle up just to keep warm when you went outside. 可知，在我的記憶中，冬天總是很不令人愉快。所以通過 keep warm可知，外出時要想暖和一些，就要多穿衣服。故選D。根據(jù)第四段中的 At the touch of a button, or through an app on our phones, the clothing generates heat from elements placed inside. 可知，只要按下按鈕，或者通過手機上 應(yīng)用程序，安裝在衣服內(nèi)部的電子元件就會產(chǎn)生熱量。故選A。根據(jù)第二段中的Fortunately, things don39。先進的技術(shù)、引擎環(huán)和設(shè)計為我們提供了解決老問題的新方法。故選C。通讀全文可知，在科技并不發(fā)達的過去，人們可能會為如何在嚴(yán)寒天氣里更好地保暖而倍感困擾。人們憑借科學(xué)技術(shù)發(fā)明了各式各樣的防寒方法。所以短文的最佳標(biāo)題為讓現(xiàn)代科技溫暖你的冬日。故選B。5．犇犇閱讀理解 Yellowstone National Park is a typical example of just how wolves can help repair an ecosystem. An October 2018 study analyzed 40 years of research on large animals inside the park.d never have seen these responses if the park hadn39。 After the wolves were reintroduced at Yellowstone, willow and cottonwood trees increased in number. The population of bears and bison also rose and what was once a ruling deerwolf interaction is now more diverse. The research is one more piece of evidence for why protecting these top predators is important not just for wolves as a species, but for hundreds of species at every level of an ecosystem. The fear they bring along may be the very angle that helps save them from dying out.（1）What does the underlined word anticipate in paragraph 3 probably mean? A.B.C.D.To introduce how wolves behave in the wild.B.To record how Aaron Wirsing observed wolves.D.It proves wolves feed on hundreds of species.B.It shows the plex relationships between species.D.The fear of wolves is beneficial to ecosystems.B.Yellowstone National Park owes its healthy ecosystems to wolves.D. （1）考查詞義猜測。故選A。根據(jù)第五段中的“To learn more about just how wolves are beneficial, a short documentary from Quest explains how the presence of wolves influences the behavior of deer, which eventually makes entire ecosystems more biologically diverse and healthy.”可知，拍攝紀(jì)錄片的目的是了解狼是如何對生態(tài)有益的。 （3）考查細節(jié)理解。故這項研究的意義在于它有助于證明保護狼的重要性。 （4）考查主旨大意。故選A。6．犇犇Choose the one that fits best according to the information given in the passage you have just read. s increased positive outlook. Our research took us in the fascinating direction of exploring how the body uses its energy.re being chased by a tiger, you don39。s cold.

So, when our body needs extra energy, one of the places it goes is our immune function.”可知我們的身體里有大量的免疫細胞，暫時停止運作是可以的。由此可以推斷，免疫系統(tǒng)會暫時停止來為身體提供額外的能量。 （2）考查詞義猜測。也就是說積極與免疫功能之間有關(guān)系，越積極，免疫功能越強，就能活得越久，所有選項中D項（樂觀與壽命）之間最切題，故選D。根據(jù)最后一段中的As a result, our immune system evolved to run in maximum amounts when we39。re not.可知當(dāng)我們快樂時，我們的免疫系統(tǒng)進化到最大程度，但是當(dāng)我們不快樂時，免疫系統(tǒng)會減弱。選D。作者開頭提出老年人更關(guān)注積極的事情，后文提到積極的情緒會增強免疫系統(tǒng)，所以本文主要講的是年齡，健康與積極的情緒之間的關(guān)系，選B。7．閱讀理解 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. 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. performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.（1）How does RAS serve elderly people? A.Through objects.C.D.It is the first robot used in daily life.Its function remains to be tested.C.It can cook for owners on its own.（3）What39。s attitude toward the future of RAS? A.Negative.C.Uncertain.（4）What can be a suitable title for the text? A.B.RAS, the first robot to make home smart.D. （1）考查細節(jié)理解。 （2）考查推理判斷。 performance…”可知，這臺機器人的表現(xiàn)還要經(jīng)過進一步的測，說明正在測試階段，故選B。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對這款機器人的未來發(fā)展充滿信心、非常樂觀，故選C。縱觀全文可知，本文介紹了一款由美國華盛頓州立大學(xué)的科學(xué)家們研發(fā)的機器人。 performance ”可知，機器人目前還在華盛頓州立大學(xué)的智能屋里進行測試，故選B。8．閱讀理解 Looking like something in a scifi movie, the pod is equipped with solar panels, which guarantee solar energy as its power. In this way the tiny home can let you live fortably wherever you travel. It even has its own shower and toilet, sleeping area for two, and a small kitchen. The 3,306 ib pods can be transported in a seacontainer, meaning the possibilities are endless.
