【文章內(nèi)容簡介】 ally diverse and healthy.”可知，拍攝紀錄片的目的是了解狼是如何對生態(tài)有益的。故選D。 （3）考查細節(jié)理解。根據(jù)最后一段中的“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.”可知，這項研究再次證明了為什么保護這些食肉動物不僅對狼這個物種很重要，而且對生態(tài)系統(tǒng)的各個層面的物種都很重要。故這項研究的意義在于它有助于證明保護狼的重要性。故選B。 （4）考查主旨大意。本文主要講述了人類以及其他動物對狼的恐懼對維持健康、平衡的生態(tài)系統(tǒng)是有益的，因為食草動物不會過度繁殖，從而保護了植物的生長。故選A。 【點評】本題考點涉及細節(jié)理解，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎(chǔ)上，進一步根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案。4．閱讀理解 A robot created by Washington State University (WSU) scientists could help elderly people with dementia (癡呆) and other limitations live independently in their own homes. 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. Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone. 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. While we are still in an early stage of development, our initial results with RAS have been promising, Minor said. The next step in the research will be to test RAS39。 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?

Numerous ruins scattered throughout the territory offer a constant reminder of the area39。s history, which makes the city always be a fascinating place for tourists. With the development of the city and more and more people moving, the city has expanded several times in size. That is why it is called New Delhi. New Delhi, a city with a population of over 20 million people, has its newest problem: never before has this city met with the worst air problem. Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has bee an annual publichealth emergency despite government vows to solve the problem. Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets. New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coalbased power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring
