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?

The robot, created by a startup called Starship Technologies in 2014, is basically a cooler on wheels。s job was to monitor how it handled various grounds, field ments from the public, and press the off switch if necessary. He said, People would also ask if it could deliver beer. It couldn39。 Broadly speaking, jobs of caring for robots fall under the umbrella of careers in automation, which include maintenance, engineering and programming. The demand for people with this skill set is considerable, with 20 million to 50 million new jobs to be expected in this category by 2030, according to the Mckinsey Global Institute. In the year that ended in June 2018, had almost three times the number of positions on the recruitment mittee that ended in June 2016.s campus while it delivered Red bull and other drinks to students. To retrieve (檢索) orders, the app encourages students to give the robot a wave。s digital eyes will roll depending on its mood. Rodriguez, who heads business development for the startup, was tasked, early on, with monitoring the KiwiBot for problems – even carrying it, should the motors fail. Since April 2018, though, the KiwiBot has largely been left unattended, and the majority of human interactions involve technical checks and loading food into the robot. To eliminate the boring work, the team is developing a restaurant robot to collect and load orders – which could happen in 2020. However, Rodriguez assured me that his staff won39。 Mckinsey estimates that millions of jobs globally could be lost to automation by 2030. A huge number of jobs will be produced as autonomous vehicles are released into the environment, Ramsey said. In 2016, Bosch started training students from Schoolcraft College, a munity college in Michigan, in autonomousvehicle repair。A factory robot.B.A restaurant robot.D.are in the category ofB.are in relation ofD.Autonomous vehicles will bee much cheaper.B.A lot of job opportunities will be created.D.Robot carers will have a petitive advantage in the future.B.We still need someone to look after robots in the future.D.本文以對相關(guān)信息進(jìn)行了介紹說明。根據(jù)第一段中的The robot, created by a startup called Starship Technologies in 2014, is basically a cooler on wheels。也就是說，Starship Technologies公司創(chuàng)造的是一款配送物品的機(jī)器人。 （2）考查詞義猜測。 （3）考查細(xì)節(jié)理解。故選C。該劃線句子的字面意思是：機(jī)器人保姆可能會覺得自己已經(jīng)獲得了未來的工作，但事實(shí)上，他們的位置可能會更好。故選A。5．閱讀理解 The Robot Activity Support System or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities.
