She was particularly dismayed by the fact that, while early interventions can improve survival rates, current detection methods are costly, time-consuming and require complex tools and constant refrigeration, she noted in her project’s description.‎ Olivia got guidance from her science research teacher and direction from past research according to Greenwich Time, and looked to detection mechanisms that have proven to work with other diseases, including HIV, Lyme disease and yellow fever.‎ “We have to work together to find answers to the enormous challenges that threaten global health, our environment and our world,” she told Greenwich Time.‎ The Connecticut teen, who hopes to one day become a physician and work with an aid organization like Doctors Without Borders, was named the Google Science Fair winner after the competition had been reduced to 20 contestants （参赛者）from across the globe. The fair is open to students in most countries between in the ages of 13 and 18.‎ Olivia hopes her success will inspire other girls interested in science and computers.‎ ‎“I would just encourage girls just to try it in the beginning, remind them that they don’t have to feel naturally drawn or feel like they have a special talent for math or science,” she told CNBC.‎ ‎25.What can be typical of Olivia’s Ebola detection method?‎ A.Infective B.Complex C.Time-consuming D.Cheap ‎26.What can be learned about other current Ebola detection methods?‎ A.They need to be conducted in cold storage B.They must gather a lot of liquid samples C.They can also detect other deadly viruses D.They have proved threats to global health ‎27.Whom is the Google Science Fair Designed for?‎ A.Physician B.Adults C.Teenagers D.Girls ‎28.What would be the best title for the passage?‎ A.Practice Makes Perfect B.Interest Is The Mother Of Success C.A Teen Girl Calls For A Special Talent For Science D.Teen Wins Huge Google Prize For Her Ebola Detection C ‎ Charles Dickens is often thought of as one of the greatest British writers.February 7 marked the 200th anniversary of his birthday. Yet for many, his language is old-fashioned and his stories often improbable. So why do so many people know and read Dickens today?‎ ‎ One reason is the British government’s insistence that every child studies a Dickens novel at school. Alongside William Shakespeare, Dickens is on every English literature school reading list.‎ ‎ His stories, though often long by today’s standards, are great moral tales. They are filled with colorful characters.Earlier this month, a ceremony was held in Portsmouth, where Dickens was born. Prince Charles said at the ceremony, “Dickens used his creative genius to campaign passionately （热情地）for social justice… His characterization is as fresh today as on the day it was written.”‎ His books stand out from many other writers because of his insight into human nature. Dickens, like Shakespeare, tells us truths about human behavior. They are as true in the 21st century as they were to his readers in the 19th century.‎ Readers have returned to Dickens’ books again and again over the years to see what he has to say about their own times.‎ ‎ No surprise then that it was Dickens whom Britons turned to during the economic crisis in the last couple of years. Dickens helped them make sense of a world that was rapidly falling apart. The BBC adapted one of his less well-known novels, Little Dorrit, into a popular television drama that introduced many Brits to the novel for the first time. A dark story about greed and money, it was the perfect illustration of bad times.‎ ‎ As long as Dickens’s novels have something to say to modern audiences, it seems likely that he will remain one of Britain’s best-loved writers.‎ ‎29.What makes Dickens a best-loved writer in modern Britain?‎ A.His novels’ realistic significance to modern readers B.His novels’ being popular among young people C.The British government’s requiring his novels for study D.His novels’ being as valuable as Shakespeare’s ‎30.What can be inferred from the passage?‎ A.It’s better to read Dickens’ in bad times B.Dickens had a good understanding of human nature C.Human nature seems worse in bad times D.The writer quite appreciates Dickens’ language ‎31.Which of the following is TRUE about Little Dorrit?‎ A.It is one of Dickens’ best-known novels B.It helps people out of economic crisis C.It talks about love and money D.It provides a perfect picture of had times ‎32.Dicken’s novels are especially instructive for those who care about .‎ A.English literature B.school textbooks C.human behavor D.William Shakespeare’s D ‎ If you want to be a citizen scientist, the National Science Foundation(NSF) has got you covered. NSF supports citizen science and crowed-sourcing efforts across all area of science, whether your passion（热情）is scanning the night sky,exploring your own backyard playing video games.‎ Join a Flock of Birders ‎ eBird is an online platform that allows bird-watchers to record their sightings-both unusual visitors and regular ones-on a massive online database.With more 100,000 active users,eBird involves bird population, distribution（分布）and habitat that users can explore in real time. In May 2015, there were 9.5 million records uploaded. ebird is a joint project between the Cornell Lab of Orimithology and the National Audubon Society.‎ ‎ Count Every Drop ‎ The Community Collaborative Rain and snow Network is the largest provider of daily rainfall observations in the United States.Volunteers set up rain instruments and record data every time a rain, or snow storm passes.Data is organized and shared on the CoCoRaHS website,and used by the National Weather Service,scientists,farmers and more.‎ Join the Plankton Party Without plankton（浮游生物）,life in the ocean would not exist.These tiny organisms（微生物） form the base of the food chain and play an important role in the global carbon cycle.

They use computer programming to enter other people’s computers and steal their information.‎ ‎ 36 We often see news about teenagers getting arrested because of hacking into emails,bank accounts or even national security sites.You may wonder how and why they become hackers at such a young age. The report explains more the group of teenager hackers.‎ According to the report,online resources make it easy for youtj to pick up hacking. 37 And there are even websites built especially for them to attack so they can practice their skills.‎ The report also said that often the goal or the teenager hackers is not getting money,but a sense of pleasure.Xiaohao,a 15-year-old hacker from Sichuan, seemed to agree. “ 38 And we want to be known among other hackers,” he told Chengdu Commercial Daily.‎ ‎“ 39 Some can also do good activities, and that’s where we should lead the young hackers,” said Dr Alice Hutching from the University of Cambridge, the United Kingdom.‎ Hackers who do good activities are usually called white hat hackers.Instead of attacking the weakness of websites,they help find and fix them. 40 “I want to take part in the China Internet Security Conference, and maybe work in the internet industry one day,” he said.‎ A.Many of these hackers start young B.Something we hack just to see if we can C.White hat hackers usually do bad activities D.Many teenagers make a lot of money by hacking F.Luckily,not all the hackers do criminal things E.Xiaohao also wants to put his skills to good use G.Teenagers can learn the skills in hacking communities 第三部分 英语知识运用（共两节，满分45分）‎ 第一节 完形填空（共20小题；每小题1.5分，满分30分）‎ 阅读下面短文，从短文后各题所给的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项。并在答题卡上将该项涂黑。‎ Some tough but useful lessons we face are from our failures.

There are a total of four lines that are known by color: yellow, orange, red, and blue. All lines travel through San Francisco, and service runs from 5:00 a.m. to midnight. An interesting fact is that only one third of the stations are below street level; the rest are either at street level or travel high above the freeway. The average speed of the trains is 35 miles per hour, but they can go up to 80 miles an hour. The cost to ride the trains depends on how far you want to go. Many people who live in the suburbs take the train into San Francisco to go to work. This means that the system is very crowded from 7:00 a.m. to 9:00 a.m. and again from 3:00 p.m. to 6:00 p.m., but outside these times, the subway system is not very busy. This can be great if you want to get a seat, but it also means that there are fewer trains. During rush hour, trains come every 5-10 minutes, but in the middle of the day and late at night, trains come every 20-30 minutes. ‎ ‎ ‎
