【文章內(nèi)容簡(jiǎn)介】 ld39。s First Digital Teacher, a Help to StudentsD.New Zealand Will Replace Teachers in Classrooms【答案】 （1）A（2）D（3）D（4）B 【解析】【分析】本文是一篇說(shuō)明文，介紹了一款智能機(jī)器人走進(jìn)小學(xué)課堂，為孩子們講授能源可持續(xù)發(fā)展。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的“They became the world39。s first kids to be “taught” by a digital teacher”可知，他們成為世界上第一批由智能機(jī)器人老師“教”的孩子。由此可知，特殊之處在于機(jī)器人老師教他們。故選A。 （2）考查細(xì)節(jié)理解。根據(jù)第三段中的“This twoway interaction not only helps attract the students39。 attention, but also allows the program39。s developers to monitor their engagement, and make changes if needed.”即“ 這種雙向互動(dòng)不僅有助于吸引學(xué)生的注意力，還允許程序的開(kāi)發(fā)人員監(jiān)視他們的參與度，并在需要時(shí)做出更改”，由此可得出，其優(yōu)勢(shì)在于需要時(shí)，可以做出變化。故選D。 （3）考查推理判斷。根據(jù)最后一段中的“However, regardless of how popular it bees, Will is unlikely to replace human educators any time soon.”可知，Ravishankar認(rèn)為它不會(huì)在短期內(nèi)代替人類(lèi)教育工作者。故選D。 （4）考查主旨大意。根據(jù)第一段中的“While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world39。s first kids to be “taught” by a digital teacher”可知，從新學(xué)年開(kāi)始，新西蘭奧克蘭的小學(xué)生將成為世界上第一批被機(jī)器人老師教的孩子。之后文章就此展開(kāi)，由此可推斷出he World39。s First Digital Teacher Appears in Classroom最符合本文的標(biāo)題。故選B。 【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，是一篇科教類(lèi)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。4．犇犇閱讀理解 According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS. The study reports the newlydeveloped rice produces proteins that attach directly to the HIV virus. This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading. 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. The new study predicts the ricebased method will lead to longterm use of the antiHIV treatment across the developing world. Researchers said the groundbreaking discovery is realistically the only way that antiHIV bination treatments can be produced at a cost low enough for the developing world. 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. The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people. The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to people.（1）What does the author intend to do in paragraph 3? A.Stress the urgency of HIV treatments.B.Provide some data about HIV.C.Remind readers of HIV prevention.D.Introduce HIV to the public.（2）In which way will the rice be used at the lowest cost? A.By transforming it into proteins.B.By adding it to an oral drug.C.By attaching it to the HIV virus.D.By processing it into a cream.（3）What can we infer about the genetic engineering process? A.It can prevent infections of HIV.B.It can produce dangerous chemicals.C.It still requires perfecting.D.It applies to the developed world.（4）From which is the text probably taken? A.A biology textbook.B.A health magazine.C.A social webpage.D.A first aid brochure.【答案】 （1）A（2）D（3）C（4）B 【解析】【分析】本文是一篇說(shuō)明文，介紹了科學(xué)家培育出可預(yù)防艾滋病病毒感染的轉(zhuǎn)基因水稻。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(guó)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。 （1）考查推理判斷。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(wàn)人感染艾滋病毒。盡管口服藥物治療已經(jīng)有了進(jìn)展減緩了疾病的發(fā)展，但現(xiàn)在還沒(méi)有治愈艾滋病毒/艾滋病的方法”。由此可推斷出對(duì)于艾滋病的治療迫在眉睫，非常緊迫。分析選項(xiàng)可知A項(xiàng)符合題意， 故選A。 （2）考查細(xì)節(jié)理解。根據(jù)第五段中的“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.”可知，最簡(jiǎn)單、最劃算的使用方法是將大米制成面霜涂在皮膚上?！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。故選D。 （3）考查推理判斷。根據(jù)最后一段中的“The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to people.”可知，科學(xué)研究小組認(rèn)為要進(jìn)一步的測(cè)試，以確保基因工程過(guò)程不會(huì)產(chǎn)生任何可能對(duì)人類(lèi)有害的額外化學(xué)物質(zhì)。由此可推斷這種基因工程的過(guò)程還需要進(jìn)一步的完善。故選C。 （4）考查推理判斷?？v觀全文可知，本文介紹了最近的一項(xiàng)研究，一種新的轉(zhuǎn)基因水稻可以預(yù)防艾滋病病毒的感染。因此與人類(lèi)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。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科研類(lèi)閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。5．閱讀理解 Experts note that an unhealthy lifestyle can put you at great risk of heart disease and stroke. So doctors urge us to eat healthy foods, get exercise, stop smoking and limit our alcohol intake. But there is something else you can do. And it is free and easy. Smile! 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. When you feel stressed or under pressure, your body releases many natural hormones (荷爾蒙) including adrenaline and cortisol. Adrenaline increases your heart rate and blood pressure. Cortisol is the body39。s 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. However, when we are stressed for a long period, these stress hormones are e
