【正文】 awberry plant in the field. The action of machinery is truly impressive, but the baskets are still practically empty. Pitzer says the robots are able to find and pick more than 50 percent of ripe berries. That39。s not yet up to human standards. A typical worker, he says, manages to pick anywhere from 60 to 90 percent of the berries. Also, he admits, the machine is slower than human hands. On the other hand, it has some advantages. It can work right through the night. Two years later, he says, this machine will be in the fields working for real. There are weaknesses to work out, but it39。s getting there. We39。re close. he says. Strawberry panies are putting millions of dollars into this project. The reason, Gary Wishnatzki, the owner of Wish Farms says, is that it39。s getting more and more difficult to find enough people to pick his berries. The fact of the matter is, if we don39。t solve the problem of this labor shortage with automation, the industry is facing a big challenge ahead. The price of fruit is going to be much higher, Jose Santos, the leader of the farm, says. Jose is pretty convinced, though, that picking strawberries will always require people. The machines will break down, he points out. In fact, he39。s looking on the bright side. You could afford to give people a day off if you have machines behind you,” he says.（1）According to the passage, the strawberrypicking robot __________. work extra hours on GPS only to find berries on petrol just like a bus both ripe and unripe berries（2）What do people mentioned in the passage think of the strawberrypicking robot? will lead to the price of strawberries rising. keeps human workers working through night. is not very efficient at the moment but promising. will pletely take the place of human workers.（3）We know from the article that __________. have been widely used in farming seems hard for robots to exactly locate strawberries now can surely perform any work better than human workers the help of robots, strawberry panies have already earned much（4）What does the passage mainly talk about? working principle of strawberrypicking robots.39。 expectations for strawberrypicking robots. present state of strawberrypicking robots. differences between humans and strawberrypicking robots.【答案】 （1）A（2）C（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，介紹了摘草莓機(jī)器人的目前的優(yōu)點(diǎn)和缺點(diǎn)：效率不高，但可以長(zhǎng)時(shí)間工作，其缺點(diǎn)也可以改進(jìn)。未來(lái)需求大，前景廣闊。 （1）考查細(xì)節(jié)理解。根據(jù)第三段中的“It can work right through the night.”可知，機(jī)器人可以整夜工作。故選A。 （2）考查推理判斷。根據(jù)第三段中的“Pitzer says the robots are able to find and pick more than 50 percent of ripe berries. That39。s not yet up to human standards. A typical worker, he says, manages to pick anywhere from 60 to 90 percent of the berries. Also, he admits, the machine is slower than human hands.”可知，摘草莓的機(jī)器人比人手慢，沒(méi)有達(dá)到人類(lèi)采摘草莓的標(biāo)準(zhǔn)。由此可以推知，它效率不高；以及“On the other hand, it has some advantages. It can work right through the night. Two years later, he says, this machine will be in the fields working for real. ‘There are weaknesses to work out, but it39。s getting there. We39。re close.’ he says.”可知，這種機(jī)器人有弱點(diǎn)需要克服，但這些弱點(diǎn)很快就會(huì)被克服。這種機(jī)器人非常有前景。兩年之后，就會(huì)被投入使用。我們離此目標(biāo)不遠(yuǎn)了?？赏浦xC。 （3）考查推理判斷。根據(jù)第三段中的“‘It39。s remembering its path down the row. It39。s remembering where all these plants are.’ It knows all this, thanks to the superaccurate GPS. Its puter brain contains a map showing the locations of every strawberry plant in the field. The action of machinery is truly impressive, but the baskets are still practically empty. Pitzer says the robots are able to find and pick more than 50 percent of ripe berries. That39。s not yet up to human standards.”由于超級(jí)精確的GPS，機(jī)器人知道所有草莓的位置。機(jī)器的作用確實(shí)令人印象深刻，但籃子實(shí)際上仍然是空的。Pitzer說(shuō)，機(jī)器人能夠發(fā)現(xiàn)和采摘超過(guò)50%的成熟漿果。這還沒(méi)有達(dá)到人類(lèi)的標(biāo)準(zhǔn)。由此推知，雖然機(jī)器人配備有精確的GPS，但實(shí)際上，它們并不能精確地定位草莓的位置，從而導(dǎo)致采摘率不高。故選B。 （4）考查主旨大意。第一段直接了當(dāng)?shù)奶岢觯簷C(jī)器人真的很難達(dá)到人類(lèi)采摘草莓的水平。第二段和第三段主要介紹了草莓采摘機(jī)器人的特點(diǎn)和優(yōu)缺點(diǎn)（效率不高，但可以長(zhǎng)時(shí)間工作）。最后兩段對(duì)草莓采摘機(jī)器人前景的展望（未來(lái)需求大，前景廣闊）。故選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科技類(lèi)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。8．閱讀理解 Slowly but surely we39。re moving closer and closer to 5G world. From smarthome security to selfdriving cars, all the internetconnected devices in your life will be able to talk to each other at lightningfast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of Mbps. But by parison 5G promises gigabit (千兆) speeds. 5G is one of those signs, along with artificial intelligence, of this ing data age, said Steve Koenig, senior director of market research for the Consumer Technology Association. The selfdriving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data ing from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It39。s pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基礎(chǔ)設(shè)施) construction. There39。s lots of data behind that task, which is why we need high speed. Augmented reality glasses and virtual headset haven39。t yet broken the mainstream, but tech panies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because panies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones. Ericsson stated at February39。s Mobile World Congress how smart glasses could bee faster and lighter with a 5G connection, because instead of being weighed down with ponents, the glasses could rely on hardware for processing power. But don39。t get too excited. There39。s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn39。t concentrated only in big cities.（1）What does the author want to stress in Paragraph 1? lightingfast speed of 5G. expectation of 5G world. difference between 4G and 5G. internetconnected devices in our life.（2）What does the underlined word emblem in Paragraph 2 mean? ....（3）We can infer from the text that _____
