The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly twothirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease. They say the easiest and most costeffective way to use the rice will be to make it into a cream to be put on the skin. The HIVfighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine.Stress the urgency of HIV treatments.B.Remind readers of HIV prevention.D.By transforming it into proteins.B.By attaching it to the HIV virus.D.It can prevent infections of HIV.B.It still requires perfecting.D.A biology textbook.B.A social webpage.D.研究人員表示，這一“突破性”的發(fā)現(xiàn)是“現(xiàn)在唯一的”以低成本為發(fā)展中國家生產(chǎn)抗艾滋病毒聯(lián)合治療的方法，但還有待于進(jìn)一步的完善。根據(jù)第三段中的“nearly 37 million people were living with HIV in 2017.... Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease” 可知，“2017年全世界有近3700萬人感染艾滋病毒。由此可推斷出對于艾滋病的治療迫在眉睫，非常緊迫。 （2）考查細(xì)節(jié)理解?！皌he most costeffective”與“the lowest cost”是同義詞，“make it into a cream”與“process it into a cream”是同義的。 （3）考查推理判斷。由此可推斷這種基因工程的過程還需要進(jìn)一步的完善。 （4）考查推理判斷。因此與人類的健康有關(guān)，所以本文可能是出現(xiàn)在健康雜志上，故選B。4．犇犇Choose the one that fits best according to the information given in the passage you have read. Flippers are a third of body length。 sawtoothed trailing edge on flukes, often raised when diving Body colour is dark brown to black。 such patterns enable individual recognition 270400 olive baleen platess, minke and blue whales. The big family migrate between winter tropical breeding areas (North West Shelf, Great Barrier Reef, New Caledonia, Vanuatu, Fiii, Tonga) and summer Antarctic feeding areas. Once mon in New Zealand waters, humpbacks are now rarely seen and may migrate further offshore. Males pete for mates either by physical fight or by song. Females give birth to their young every two to three years。 Similar species: Easily identifiable due to a 39。 back when submerging, but at a distance may be confused with other species that raise their flukes when diving, such as sperm, right and blue whales.Their long flippers vary in length, size and shape like dorsal fin.B.The different colors and patterns of the body help to be recognized.D.s description of humpback whales39。They need warmer waters to breed.B.t survive in extreme cold.C.They are mostly hunted in New Zealand waters.（3）This article is mainly intended toexplain why humpbacks are still hunted in some parts of the worldB.popularize the basic knowledge of humpbacks and call for protectionD. （1）考查推理判斷 。 often extensive white on flippers and underside of body and flukes。分析選項(xiàng)可知C項(xiàng)符合題意，故選C。根據(jù)第五個(gè)小黑點(diǎn)后面的The big family migrate between winter tropical breeding areas (North West Shelf, Great Barrier Reef, New Caledonia, Vanuatu, Fiii, Tonga) and summer Antarctic feeding areas. 座頭鯨這個(gè)大家族在冬季的熱帶繁殖區(qū)（西北大陸架、大堡礁、新喀里多尼亞、瓦努阿圖、斐濟(jì)、湯加）和夏季南極喂養(yǎng)區(qū)之間遷徙。冬季的熱帶繁殖區(qū)，是溫暖的地方。 （3）考查主旨大意。所以本文目的是普及有關(guān)座頭鯨的知識，并對它們加以保護(hù)。 【點(diǎn)評】本題考點(diǎn)涉及推理判斷和主旨大意三個(gè)題型的考查，是一篇科普類閱讀，要求考生根據(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。 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. 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. 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。Through sensors.B.Through a mobile robot.Through their daily activities.（2）What can we know about RAS? A.B.It can locate people and do any task.D.s Minor39。Doubtful.B.Optimistic.D.Elderly people leave the nursing home.Smart Home Tests first elderCare robot.C.Older adults have benefited from RAS.【答案】 （1）
