A new study has found the amount of antibiotics given to farm animals is expected to increase by twothirds over the next 15 years. Researchers are linking the growing dependence on the drugs to rising demand for meat, milk and eggs. The researchers warn the drugs could quicken the development ofantibioticsresistant (耐抗生素的)infections. Such infections are already a major public health concern in the United States.Experts say when people stop living in poverty, the first thing they want to do is eat better,rather than earn more money. For most people, that means their diet should contain more meat. Increasing prosperity in Asia has meant people there are eating nearly four times as much meat, milk and dairy products as they did 50 years ago.To meet that demand, farms have put many animals into smaller spaces. As the animals are crowded together, often the easiest way to deal with some of the problems of crowding is to give them antibiotics. It’s clear that antib iotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually, and the antibiotics-resistant bacteria can spread to people.Doctors find that antibiotics that once worked against the infections no longer do. The bacteria have learned ways to fight the medicine. Doctors say the heavy use of antibiotics in animals is one of several reasons for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year. At least 23,000 die from an infection.Ramanan Laxminarayan heads the Center for Disease Dynamics, Economics and Policy. He says the problem is expected to get worse. He believes the use of antibiotics in animals will soon increase sharply. He says that will not be good for human health. He and other researchers wrote a report on the study, which was published in the Proceedings of the National Academy of Sciences. They used datafrom the United Nations that tell how and where livestock(牲畜) are raised today. They then predicted how such production would change by 2030.Europe has banned the use of antibiotics to increase animal growth. And she adds the United States is hoping to persuade farmers to stop using antibiotics for that purpose.1.What is the passage mainly about?A.How to keep farm animals healthy.B.The abuse of antibiotics in human beings.C.A new way of raising farm animals.D.The disadvantages of using antibiotics.2.From he passage, we can infer that using antibiotics too often in farm animals ______.A.will lead to animals' being less activeB.causes animals to get infected more easilyC.makes antibiotic-resistant bacteria spread to peopleD.has a negative effect on the growth of animals3.What accounts for the increasing amount of antibiotics given to farm animals?A.The increasing need for meat.B.The need for eating diversely.C.The less effective antibiotics.D.The limited farm technology.4.How will the use of antibiotics in animals according to Ramanan Laxminarayan?A.It will soon stop rising.B.It will soon increase sharply.C.It will soon rise steadily.D.It will soon increase slowly.参考答案： 1.D; 2.C; 3.A; 4.B解析： 1.[纵观全文便知,文章主要介绍了人们使用抗生素来饲养家畜带来的缺点。

Aerial(空中的) performer Jennifer Bricker was born without legs, but she never let it stop her.Wrapped in a loop(圈) of red silk hung from the ceiling, Jennifer Bricker climbs and twists to the music. Her head hangs down and her strong arms let go as she balances on her back, high above the ground—a move that is all the more daring because she has no legs.Jennifer was a few months old when she was adopted by Sharon and Gerald Bricker. She had big brown eyes, a bright smile, and huge amounts of energy. When a doctor advised her adoptive parents to carry her around in a kind of bucket(桶), they refused.Jennifer soon learned to walkand runon her hands and bottom, and grew up fearlessly climbing trees and bouncing on the trampoline(蹦床) with her three older brothers. “My parents didn’t treat me differently so I didn’t grasp the concept that I was different. I knew I didn’t have legs but that wasn’t stopping m e from doing the things I wanted to do.”At the age of three she was fitted with artificial legs, but she never really took to them—she moved more freely without them.In 1996 the Olympic Games took place in Atlanta. Jennifer loved to watch the women’s gymnastics team, and especially adored the 14yearold Dominique Moceanu who competed for the U．S. When Moceanu and the women’s team won the gold, Jennifer decided she was going to be a gymnast, too. She took up power tumbling, which involves performing floor exercises down a runway. But Jennifer did not want any allowances to be made for her disability.At the age of 10 she took part in the Junior Olympics and by age 11 she was thetumbling champion for the state of Illinois.Jennifer now travels the world as an inspirational speaker and acts as an aerial performer.【解题导语】本文是一篇人物记叙文。

More and more visitors, especially young people, are finding their way onto the train lines, especially those near flowerbeds and spring blossoms.

drone(无人机) can follow hiking trails(小路) without a pilot’s assistance.This could allow rescuers to search more eff iciently.Scientists outfitted a craft with a single camera.As the drone’s “eye”,the camera pointed forwards.But having an eye wasn’t enough.The drone also needed a “brain” to understand what it wasseeing.And that brain would have to recognize what constitutes a trail.Camera images,however,can be very difficult for a computer to interpret,study leader Alessandro Giusti notes.So he and his team used photos of forest trails to train their drone’s neural network(神经网络).They attached three GoPro cameras to a single headband.One camera pointed straight forward.The other two were directed 30 degrees to the right and left of the centre.A hiker put the package on and then hit the trails in a forested part of Switzerland.Over several weeks,the cameras recorded a total of 8 hours of video covering 7 kilometres of trails.The researchers then divided the video into individual still images to train the neural network.The network learned to identify what a trail looked like.The team then tested the program with unused images from the video.The computer did a slightly better job than the people had in correctly classifying the images.This meant the drone was ready to navigate the real world on its own.Giusti and his team took their now “smart” device to a forest with trails that had not been used in the drone’s training.It flew along the path,constantly adjusting its direction based on the images coming in through its camera.The drone didn’t perform as well in real-life as it did in the lab,Giusti admits.That’s because the drone’s camera took lower-quality images than the cameras that had been used to train it.As a result,the images being taken by the drone looked different,he explains.This confused its neural network.“It’s an exciting use for neural networks,” says Christ opher Rasmussen,a computer-vision scientist who was not involved with the study.“However,the problems faced in the experiments show that there are still some important issues to be worked out.”1.The “smart” drone has been created in order to help .A.find travelers who get lostB.ensure the safety of travelersC.deliver necessities to travelersD.show travelers the way to a place2.While being tested to classify the images in the lab,the computer .A.did as well as the

experiments?A.Critical.B.Doubtful.C.Objective.D.Optimistic.B(2016·石家庄调研检测)Shopping centres,stadiums and universities may soon have a new tool to help fight crime.A California company called Knightscope says its robots can predict and prevent crime.Knightscope says the goal is to reduce crime by half in areas the robots guard.William Santana Li is the chief executive officer of Knightscope.He says,“These robot security guards will change the world.Our planet has seven billion people on it.It’s going to quickly get to nine billion people.The security equipment that we have globally is just not going to develop that fast.The compan y’s Autonomous Data Machines can become the eyes and ears of law enforcement (执行).”“You want it to be machines plus humans.Let the machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work,so it’s always working all together.”The machines are one and a half meters tall and weigh 136 kilograms.They do not carry weapons but they have day-and-night time video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.Some people may become concerned about their privacy,especially in connection with the video recordings.Some people may worry that such recordings will appear on the Internet.Eugene Volokh,a law professor at the University of California,says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.William Santana Li says there is a long waiting list for the robots in the US.Workers in the company are working overtime to meet the demands of the market.At least 25 other countries are also interested in these robotic security guards.5.What can this new tool do for humans?A.Make strategic decisions.B.Keep watching day and night.C.Carry heavy weapons.D.Stop crime autonomously.6.Why are people worried?A.Their privacy may be let out.B.The robots are very expensive.C.Robots will replace humans.D.They will be out of work soon.7.Which of the following can be the best title of the text?A.Robots Are Becoming More PopularB.Robots Contribute a Lot to

The products displayed at the entrance? Or the soft background music?But have you ever notice the smel l? Unless it is bad, the answer is likely to be no. But while a shop’s scent may not be outstanding compared with sights and sounds, it is certainly there. And it is providing to be an increasing powerful tool in encouraging people to purchase.A brand store has become famous for its distinctive scent which floats through the fairly dark hall and out to the entrance, via scent machines. A smell may be attractive but it may not just be used for freshening air. One sports goods company once reported that whe n it first introduced scent into its stores, customers’ intension to purchase increased by 80 percent.When it comes to the best shopping streets in Pairs, scent is just as important to a brand’s success as the quality of its window displays and goods on sale. That is mainly because shopping is a very different experience to what it used to be.Now the rise of electronic commerce (e-commerce)has opened up famous brands to a wider audience. But while e-shops can use sights and sounds, only bricks-and-mortar shops(实体店)can offer a full experience from the minute customers step through the door to the moment they leave. Another brand store seeks to be much more than a shop, but rather a destination. And scent is just one way to achieve this.Now, a famous store uses complex man-made smell to make sure that the soft scent of baby powder floatsthrough the kid department, and coconut scent in the swimsuit section. A department store has even opened a new lab, inviting customers on a journey into the store’s wind ows to smell books, pots and drawers, in search of their perfect scent.1. According to the passage, what is an increasingly powerful tool in the success of some brand store?A.Friendly assistant.B.Unique scents.C.Soft background musicD.Attractive window display.2. E-shops are mentioned in the passage to _______ .A. show the advantages of brick-and-mortar storesB. urge shop assistants to change their attitudeC. push stores to use sights and soundsD. introduce the rise of e-commerce3. Which statement would the writer agree with?A.Put different shop on the products on display.B.Ask every shop assistant to wear light perfume.C.Place fragrant flowers in the shopD.Expose some coffee bean to air inside a coffee shop.4. The main purpose of the passage is to ______ .A. compare and evaluateB. examine and assessC. inform and explainD. argue and discuss【语篇解读】本文是一篇说明文。

在日本的一个小镇，人们在一个小时内堆了1585个雪人，打破了先前创造的一个小时内堆1279个雪人的纪录。

1．made 考查动词的时态。

堆雪人是过去发生的事，所以用一般过去时。

2．earlier 考查形容词的比较级。

此处指一个小时内堆1,279个雪人是早前的纪录，和1,585的记录进行比较，故空格处用比较级。

3．which 考查定语从句的引导词。

先行词为record，指物，故用which引导非限制性定语从句。

4．a 考查冠词。

此处表泛指，故用不定冠词a。

5．although/though 考查连词。

根据语境可知，空格处应用连词although/though引导让步状语从句，指“虽然小镇被雪覆盖，但居民们还是情绪高涨，共同迎接挑战”。
