【正文】 akes food less palatable to predators.t know how appealing it is.（1）The sea hare defends itself from predators by ________. A.giving out purple ink to make itself invisible to predatorsC.giving off smelly gas to try to drive predators away（2）Which of the following statements is TRUE according to the passage? A.The opossum fakes its death to avoid being targeted by predators.C.The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________. A.B.C.D. （1）考查細(xì)節(jié)理解。Sea Hare (海兔)部分中的“The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.”可知，海兔身上散發(fā)出黏糊糊的紫色墨水，這種物質(zhì)使得捕食者對(duì)食物不那么感興趣，從而保護(hù)自己免受捕食者的傷害。 （2）考查細(xì)節(jié)理解。Opossum (負(fù)鼠)部分中的“In order to bee ‘dead’, they don39。故選B。根據(jù)Millipedes (千足蟲)部分中的“Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.”可知，千足蟲主要防守是蜷成一團(tuán)。眼睛，并在攻擊者身上留下可怕的氣味。故選C。3．犇犇閱讀理解 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 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(xiàng)可知A項(xiàng)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(jiǎn)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(cè)試，以確保基因工程過程不會(huì)產(chǎn)生任何可能對(duì)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(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。 【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。 Stocky, slowmoving whale, rarely grows beyond 15 metres in length variable dorsal fin size and shape。 Bumpy tubercles on top of head often extensive white on flippers and underside of body and flukes。 Bushy blow, occasionally Vshaped Humpback whales belong to the rorqual (groovethroated) family, which includes fin, sei, Bryde39。 some nonbreeding females probably remain in the southern waters during winter. Young humpback whales return to their area of birth but in later life some wander between breeding areas. Humpbacks eat small shrimps and other schooling prey, such as fish, forming small, cooperative groups of two to three individuals to feed.hump39。 Protection status: Recovering well from past whaling and now numerous in some former migration and aggregation areas, rarely seen in others.（1）Which of the following is TRUE about humpback whales? A.They are large and likely to grow longer than 15 metres.C.Their bumpy tubercles and blowholes are on both sides of head.（2）Which of the following can be inferred from this article39。 migration? A.They can39。They find plentiful food in tropical waters.D. . A.introduce how humpbacks migrate through some dangerous watersC.help distinguish humpbacks from other similar species【答案】 （1）C（2）A（3）C 【解析】【分析】本文是一篇說明文，介紹了座頭鯨外形特點(diǎn)、體重、顏色，以及其如何繁殖、喂養(yǎng)等生活習(xí)性等，并呼吁大家保護(hù)它。根據(jù)第四個(gè)小點(diǎn)后的一段Body color is dark brown to black。 such patterns enable individual recognition可知，座頭鯨體色由深棕色至黑色，腳蹼、身體底部和尾鰭上通常是大面積的白色；這樣的圖案使單個(gè)的座頭鯨很容易被識(shí)別。 （2）考查推理判斷?？芍?，座頭鯨在熱帶地區(qū)繁殖?？芍^鯨需要在暖和的地方繁殖，故選A。本文主要對(duì)座頭鯨外形特點(diǎn)、體重、顏色，以及其如何繁殖喂養(yǎng)等生活習(xí)性等作了介紹，并呼吁大家保護(hù)意識(shí)。分析選項(xiàng)可知C項(xiàng)符合題意，故選C。5．犇犇Choose the one that fits best according to the information given in the passage you have just read.

Everyone holds double roles in the pany. Greater robot selfgoverning just means employees will shift their focus to accounting, engineering, and design. Toyota has trained students in maintenance as well. We might even see a return to lowlevel jobs where people e and fuel the car for you, Ramsey said. Until we can wirelessly charge, someone needs to refuel them. The hardesttoautomate industries, as it happens, are the ones that require looking after humans, such as childcare, education and health care. Robot babysitters might feel like they have scored the job of the future, but in fact, they might be better positioned.（1）What kind of robot is the one created by a startup called Starship Tec
