t avoiding an attack, that bee is focused on something else entirely: me. 縱觀全文可知,本文介紹了最近的一項研究,一種新的轉(zhuǎn)基因水稻可以預(yù)防艾滋病病毒的感染。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)一步的測試,以確保基因工程過程不會產(chǎn)生任何可能對人類有害的額外化學(xué)物質(zhì)。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,最簡單、最劃算的使用方法是將大米制成面霜涂在皮膚上。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)在還沒有治愈艾滋病毒/艾滋病的方法”。A first aid brochure.【答案】 (1)A(2)D(3)C(4)B 【解析】【分析】本文是一篇說明文,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。It applies to the developed world.(4)From which is the text probably taken? A.By processing it into a cream.(3)What can we infer about the genetic engineering process? A.Introduce HIV to the public.(2)In which way will the rice be used at the lowest cost? A. 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. 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.Remind readers of HIV prevention.D.By attaching it to the HIV virus.D.It still requires perfecting.D.A social webpage.D.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。 (2)考查細(xì)節(jié)理解。 (3)考查推理判斷。 (4)考查推理判斷。2.犇犇閱讀下列短文,從每題所給的A、B、C和D四個選項中,選出最佳選項。 One spring day, once the flowers have begun to open, a bee will hover (盤旋) and zip through your yard and divebomb your piic table. While you39。 A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, strawlike tongue into a hundred or so flowers. When the bee has had her fill, shell fly home. There the bee will deposit what she has got into the mouth of one of her coworkers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the b. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4, 000 flowers, and yet will produce only onetwelfth of a tea spoon of me.The flowerWater special talent hard work.C. social behavior.(3)What is the purpose of the passage? A.To talk about the history of a treasure.C.To argue against the control of chemicals.【答案】 (1)D(2)B(3)A 【解析】【分析】本文是一篇說明文,用擬人的手法,以蜂蜜的口吻,介紹了蜜蜂雖然只有六周左右的壽命,但用其一生辛勤為人類釀造蜂蜜,人類應(yīng)該保護(hù)蜜蜂。 (2)考查主旨大意。 【點評】本題考點涉及代詞指代,推理判斷和主旨大意三個題型的考查,是一篇科普類閱讀,考生需要根據(jù)上下文進(jìn)行邏輯推理,概括歸納,從而選出正確答案。 In our twenties, we find it funny when we can39。s disease(老年癡呆癥)?t worry. The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer39。The memory of the young is better than the old.C.s a rare phenomenon when young people forget something.(2)What statement does the researchers in the new study agree with?

But it es from an idea of the past.”和第五段“He pared it to the milkman model of the 1950s in the United States. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste.”可知,Loop購物模式的想法來自于過去送奶工模式,是一種可以杜絕零浪費的模式。故選D。 【點評】本題考點涉及細(xì)節(jié)理解,推理判斷和主旨大意三個題型的考查,是一篇環(huán)保類閱讀,考生需要準(zhǔn)確掌握細(xì)節(jié)信息,并根據(jù)上下文進(jìn)行邏輯推理,概括歸納,從而選出正確答案。 Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on hi
