【正文】 preading. 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. 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.Provide some data about HIV.C.Introduce HIV to the public.（2）In which way will the rice be used at the lowest cost? A.By adding it to an oral drug.C.By processing it into a cream.（3）What can we infer about the genetic engineering process? A.It can produce dangerous chemicals.C.It applies to the developed world.（4）From which is the text probably taken? A.A health magazine.C.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。 （1）考查推理判斷。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”。分析選項可知A項符合題意， 故選A。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。故選D。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)。故選C。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。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。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! 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。However, when we are stressed for a long period, these stress hormones are everpresent in our bodies. And that, medical researchers warn, may lead to health problems. Dr. Chockalingam says a smile may be one way to help. He tells his patients to smile 20 times an hour. To some, that might seem like a lot of smiling. Or some might even feel foolish ... smiling for seemingly no reason. But a smile does not involve drugs. It is not invasive like a surgical operation. It is free and it has no bad side effects. s heart health.（1）Which of the following agrees with Dr. Chockalingam39。同時說明了微笑有利于健康的原因和人們感到壓力時的身體反應(yīng)等情況。根據(jù)第二段中的“When we smile, the brain wiring changes. The chemicals that are released are more positive.”當(dāng)我們微笑時，大腦的線路會發(fā)生變化?？芍珻hockalingam博士認(rèn)為微笑能使我們的身體產(chǎn)生有益的化學(xué)物質(zhì)。 （2）考查細(xì)節(jié)理解?？芍?，當(dāng)我們處于危險中時，壓力荷爾蒙可以幫助我們。 （3）考查細(xì)節(jié)理解。s heart health.”如果我們微笑，我們就打破了壓力和健康之間的聯(lián)系?？芍?，Chockalingam博士認(rèn)為微笑可以使我們放松，從而有利于我們的健康。 （4）考查主旨大意。他說，微笑可能是幫助心臟的一種方式。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解和主旨大意兩個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進(jìn)行概括和歸納，從而選出正確答案。Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you39。If this is you, you39。 mouths water? t tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆蟲學(xué)) at the University of Florida in the US, told NBC it39。Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻擊對象) by smelling the carbon dioxide (CO2) breathed out by humans and animals. That39。Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, Mosquitoes start orienting (使......朝向) themselves to carbon dioxide and keep flying upwind as they sense higher concentrations (濃度). t get bitten as much ... as adults, US professor Ted Rosen told Science Alert. t pregnant. According to Live Science, mosquitoes can lock onto targets from up to 50 meters away. At this distance, what we wear has a huge effect. Due to their vision (視覺), people wearing dark colors are more likely to bee targets. t worry. Some simple tips can help ward them off. Scientists remend that we use insect repellent (驅(qū)蟲劑) and wear lightcolored clothing.（1）How do mosquitoes locate their targets, according to the article? seeking out bright clothes. identifying different blood types. sensing an increase of carbon dioxide. following bigger crowds.（2）Why are pregnant women more likely to be bitten by mosquitoes? larger size helps mosquitoes to see them. breathe out more CO2. are more likely to sweat. body temperatures are higher.（3）How does the article advise you to avoid mosquitoes? regularly. lightcolored clothing. your skin dry and clean. indoors in the evening.（4）What39。 （1）考查細(xì)節(jié)理解。它們通過聞人和動物呼出的二氧化碳來鎖定目標(biāo)；以及第五段中的“Mosquitoes start orienting themselves to carbon dioxide and keep flying upwind as they sense higher concentrations”蚊子開始飛向有二氧化碳的地方，當(dāng)它們感知到高濃度的二氧化碳時，就保持逆流飛行，可知，蚊子通過感知二氧化碳的增加來鎖定目標(biāo)。 （2）考查細(xì)節(jié)理解。t pregnant.”對二氧化碳的喜歡使得孕婦很容易被蚊子咬，因為她們比正常相同年齡，相同體型的人呼出多余21%的二氧化碳，可知，孕婦呼出更多的二氧化碳，所以更招蚊子咬。 （3）考查細(xì)節(jié)理解?？芍?，文章建議我們可以通過穿淺色衣服來避免蚊子叮咬。 （4）考查主旨大意。 mouths water?”根據(jù)Smithsonian雜志，世界上大約20%的人容易招蚊子咬。故選D。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.
