9、制住做某事的欲望”，故B项符合文义。答案：B3Who is the text intended for?AThose who usually choose first class for their flights.BThose who want to find suggestions on where to fly.CThose who are travelling during the spring break.DThose who are looking for the best airline ticket prices.解析：推理判断题。根据第一段可知，如果你明年要休假并打算乘飞机旅

10、行，这里有一些有用的购买便宜机票的建议，故可推知，本文是写给那些寻找最佳机票价格的人，故D项正确。答案：DB(2020开封一模)Dont like seeds in your tomatoes？You might be pleased to know that seedless ones have been created by gene editing.This could create a wide range of seedless fruits，but few may ever be seen in the supermarket if regulators decide to tre

11、at geneedited crops in the same way as genetically engineered(转基因的)ones.Several seedless fruits，from bananas to grapes，are already available，but have mostly appeared by luck rather than design.And although there are a few seedless varieties of tomatoes，theyve taken researchers many years to create.N

12、ow it can be done very quickly，as Keishi Osakabe at Tokushima University in Japan has shown.His team used the CRISPR geneediting technology to make fruits develop even though no seeds had begun to form.“We havent tasted them yet，but in theory they should taste the same，” says Osakabe.There have been

13、 a few efforts to create seedless tomatoes using earlier genetic engineering techniques.These methods take longer time compared with CRISPR.Some “seedless” fruits just have very small seeds，and still require pollination(授粉)But completely seedless fruits like the edited tomatoes do not require pollin

14、ation at all.Such plants could improve food security by reducing our reliance on smaller bee populations，says Saul Cunningham at the Australian National University.Many fruit growers buy bees to pollinate their crops.There is a deficiency for farmers，however.Seedless plants usually have to be grown

15、from cuttings，which involves more labor than planting seeds.CRISPR could be used to develop other types of fruit that dont require pollinators，as well as introduce beneficial mutations(突变)，says Osakabe.But to make it on to the supermarket，geneedited plants may have to meet the same standards as gene

16、tically engineered plants，which would greatly increase costs.Some argue that since gene editing is used to introduce mutations already found in some of the plants we eat，it should not require such strict regulations.语篇解读该文主要介绍了使用基因编辑技术可以更快地培育出无籽或无核水果，但这种水果要想进入超市，可能必须符合与转基因水果相同的标准。4What has been the

17、problem with seedless tomatoes created in the past?ATheir taste was not very good.BThey still had a few big seeds.CTheir genes could not be recognized.DThey took quite a long time to create.解析：细节理解题。根据第三段中的“theyve taken researchers many years to create”和第五段中的“These methods take longer time compared

18、with CRISPR.”可知，过去培育无籽西红柿很耗时，故选D。答案：D5What did Keishi Osakabes team do?AThey edited tomatoes genes.BThey changed the taste of tomatoes.CThey made seedless bananas and grapes.DThey created genetically engineered tomatoes.解析：细节理解题。根据第四段中的“His team used the CRISPR geneediting technology to.no seeds had

19、 begun to form.”可知，Keishi Osakabe的团队编辑了西红柿的基因，故A项正确。答案：A6Why is CRISPR better than previous methods?AIt will still require pollination.BIt will remain unaffected without bees.CIt will reduce peoples reliance on food security.DIt will make many growers buy bees for pollination.解析：推理判断题。根据第八段中的“CRISPR

20、 could be used to develop other types of fruit that dont require pollinators.”可知，CRISPR可用于研制其他类型的不需要传粉者的水果，由此可推知，CRISPR不会受到没有蜜蜂的影响，故选B。答案：B7What does the underlined word “deficiency” in Paragraph 7 probably mean?ADanger.BDisadvantage.CBenefit. DSolution.解析：词义猜测题。根据第七段中的“Seedless plants usually have

21、to be grown from cuttings，which involves more labor than planting seeds.”可知，种植无籽植物通常需要投入更多劳动，由此可推知，这对农民来说并不是什么好事，故画线词的含义与B项词义最接近。danger“危险”，disadvantage“劣势”，benefit “益处”，solution “解决办法”。答案：B词汇积累：Para.1：seedless adj.无籽的，无核的第6题：unaffected adj.未受影响的构词：gene n基因genetic adj.基因的；遗传学的genetically adv.从遗传学角度；

22、从基因方面genetics n遗传学regulate v(用规则条例)约束，控制，管理regulator n(某行业等的)监管者，监管机构regulation n规章制度；规则；法规pollinate vt.授粉，传粉pollination n授粉pollinator n传花粉者难句分析：But to make it on to the supermarket，geneedited plants may have to meet the same standards as genetically engineered plants，which would greatly increase co

23、sts.(Para.9)分析：the same.as.意为“与相同的”；which引导非限制性定语从句，在从句中作主语，该从句修饰“geneedited plants may have to.genetically engineered plants”。译文：但是，要进入超市，基因编辑植物可能必须符合与转基因植物相同的标准，这将大大地增加成本。C(2020广州阶段考试)The Silk Road is arguably the most famous longdistance trade route of the ancient world.This passage connected Eur

32、 around the edges of the desert.CTravelers staying there were often attacked by criminals.DThey were shared by travelers from different countries.解析：推理判断题。根据第四段中的“These places also promoted the exchange of goods，and even ideas，amongst the travelers who stopped there.”可推知，休息处接待来自不同国家的旅客，故选D。答案：D11Wha

33、t is the passage mainly about?AThe origins of the Silk Road.BThe benefits of the Silk Road.CThe difficulties faced by Silk Road travelers.DThe cultural exchanges among Silk Road travelers.解析：主旨大意题。根据文章结构可知，作者在第一段给出了中心句“Although merchants could make huge profits traveling on the road，it was not without risk.”，在中间几段讲述了商旅们在戈壁滩上面临的困难以及其他危险，最后一段再次强调即使过了戈壁滩，但还有其他危险等待着他们，故选C。答案：C词汇积累：Para.1：arguably adv.可以说Para.2：commence v开始；着手Para.3：trader n商人sandy adj.铺满沙子的；含沙的
