I use Duolingo to practice Spanish and German. In the app, you can access resources such as Duolingo Stories, which can allow you to check your comprehension skills as you go. I also subscribe to Premium for $10 per month which includes an ad-free experience and downloadable lessons.MemriseOne of my favorite parts of Memrise is its short videos about how real locals express different phrases in conversation. A few lessons are available for free daily, but the full program is accessible if you subscribe to Memrise Pro. There are three plans—one month for $9, a year for $30 or three months for $19.BusuuWhen you sign up for Busuu, you select the language you want to learn, and the app helps you determine how advanced you are with it and why you want to learn it, and to what level. From there, you set a daily study goal. Premium costs about $6 per month for a year.LiricaIf you listen to any song enough, you'll learn all the words through repetition, even if they're in a different language. But how do you figure out what they mean? This is where Lirica comes in. This app is unique in how it approaches teaching Spanish. Instead of traditional teaching methods for learning a language, Lirica uses popular music by Latin artists to help you learn the Spanish language and grammar.

It enables users to learn Spanish through music.BOnce small farmers in Masii, a remote village in Kenya, have picked their crops, all they can do is wait until a buyer trucks through. The system works fairly well for beans and corn, but mangoes-the area’s other main crop-spoil (腐烂) more quickly. If the trader is late, they rot.However, a simple coating could change that. A company, SmartTech, has created a product that doubles the shelf life of fresh produce, enabling farmers to access far-off, larger markets. More time forfresh produce on grocers’ shelves also means less food waste-a $2.6 trillion problem, according to the United Nations’ Food and Agriculture Organization (FAO).James Rogers, CEO of SmartTech, wanted to solve the problem for food much in the same way that oxide barriers preventing rust (锈) have achieved for steel. Fortunately, researchers have found when plants made the jump from water to land, they developed cutin(蜡质), a barrier which is made of fatty acids that link together to form a seal around the plant, helping keep water in.The cutin was such a grand strategy that today you’ll still find it across the plant kingdom. SmartTech discovered through researches that an orange can last longer than a strawberry not so much because of the thickness of its skin, but because of the difference in the arrangement of those cutin molecules (分子)on the surface. After extensive trials, Rogers and his team developed a natural and tasteless protective coating from plant material-stems, leaves and skins. The product extends the sweet spot between ripening and rot. And best of all, the treated produce doesn’t require refrigeration.“SmartTech has huge potential to turn poor farmers in Africa into commercial farmers,” says Rogers. “That means more money in pockets, and more food in stomachs.” But whether the company can cost-effectively reach small farmers in far-off areas still remains a challenge.4. The author mentions the small farmers in Kenya to ________.A. stress their need for preserving produceB. show their challenge in harvesting cropsC. express their wish to reach larger marketsD. evaluate their loss caused by slow transport5. What can we learn about SmartTech’s product?A. It is financially supported by FAO.B. It is intended to replace refrigeration.C. It is designed to thicken produce’s skin.D. It is based on plants’own defence system.6. What will James Rogers probably focus on next?A. How to expand farms.B. How to earn more money.C. How to produce more tasty food.D. How to profit farmers in remote area.7. The main purpose of the passage is to ________.A. promote a productB. present a technologyC. advertise SmartTechD. introduce James RogersCIn the past, most people received their news from newspapers, magazines, radio and TV. But now, almost anyone can report and publish on the Internet and share it as news through social media. But the problemis that not all of the information is true and not all of the reporting is trustworthy.Howard Schneider, a former editor of the newspapersNewsday,started the Center for News Literacy (素养) at Stony Book University in 2007. The center has multiple projects, but the most famous one is a course to teach news literacy. The course trains students to look for various details that may indicate the truth of the story.Michelle Sheng is a third-year student at theUniversityofMichigan. Sheng finds that students either just stop reading the news or only take news from one source that they trust. "A lot of people are tired of the news. People are too busy to keep up with the news, and it is really easy to take whatever news is given to you because you don’t have the time to figure it out yourself,“ she says.For her part, Sheng recently created a digital exhibit for the university library of images to educate students on steps they can take to better analyze the news.It is important to educate an even larger audience, beyond American university students. The Center for News Literacy has developed teaching resources, as well as a free online news literacy course. It is also trying to reach a younger audience. It has partnered with several secondary schools in the American state ofNew Yorktoteach news literacy.People should research and confirm what they read online. However, to change human behavior is a difficult thing, but that really is the only thing that is going to help. The biggest problem is not getting people to be able to recognize bad journalism or false news, but getting people to want to recognize it. Our brains are wired to the Internet to seek out information that agrees with our current beliefs.8. What’s purpose of the course “News Literacy”？A. To get rid of false information on the Internet.B. To make people realize the risk on the Internet.C. To train students to tell true information from the false.D. To teach students good habits of using information online.9. Why do students have difficulty judging the truth of news?A. They are too lazy.B. They are bored with news.C. They lack news resources.D. They lack time to check its realness.10. What does the Center try to do besides teaching university students?A. Educate the public.B. Improve the service online.C. Prevent children going online.D. Set up several secondary schools.11. What did the author suggest doing to solve the problem of false news?A. Believing whatever you see.B. Changing human behaviors.C. Questioning all the news online.D. Only trusting reliable information.DHumans are the only creature that gets around by standing up and putting one foot in front of the other. Our ability to walk upright has allowed humankind to travel great distances and survive changing climates, environments and landscapes.Countless scientific studies have found that walking is really good for us and this simple act can provide anumber of healthimplications, which help people live longer. In fact, a walking routine, if done properly, might be the only exercise people need.How much walking should one aim for? You’ve likely heard we need 10,000 steps a day. That’s about 5 miles. But contrary to popular belief, this recommendation doesn’t come from science. Instead, itis from a 1960s advertising campaign to promote a pedometer (计步器) in Japan. Perhaps because it’s a round number and easy to remember, it stuck.Since the 1960s, researchers have studied the 10,000-steps-a-day standard and have turned up mixed results. Although 10,000 steps is certainly a healthy and worthwhile goal, it’s not fit for all.For instance, a recent Harvard University study involving more than 16,000 senior women found that those who got at least 4,400 steps a day greatly reduced their risk of dying early when compared with less active women. The study also noted that these benefits continued up to 7,500 steps. This 7,500 mark isn’t surprising: It’s similar to common public health recommendations, such as the Centers for Disease Control and Prevention’s recommendation of 150 minutes of moderate (适度的) physical activity a week for adults.12. What does the underlined word “implications” in Paragraph 2 refer to?A. BenefitsB. Problems.C. Habits.D. Manners.13. Where does the 10,000-steps-a-day standard come from?A. A Harvard University study.B. Science research on health.C. A pedometer advertisement.D. Public health recommendation.14. What can we know from the last paragraph?A. 7,500-steps-a-day standard is the best choice for all.B. More than 16,000 old people were involved in the study.C. Those who walk at least 4,400 steps a day won’t die early.D. 150-minute moderate exercise a week for adults is advised.15. What does the author mainly want to tell readers?A. The more you walk a day, the healthier you will be.B. We can benefit from continuous and proper walking.C. Walking upright helps humankind to explore the world.D. Advertisements can always tell us some scientific suggestions .第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
