Malaria (疟疾), the world's most widespread parasitic (寄生虫引起的) disease, kills as many as three million people every year - almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease,although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania,Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and,often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite. Together, the
mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations.Some of the disease's spread is due to global warming.
For decads, the first-choice treatment for malaria parasites in Africa has been chloroquine,a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world,malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

The freezing Northeast hasn’t been a terribly fun place to spend time this winter, so when the chance came for a weekend to Sarasota, Florida, my bags were packed before you could say “sunshine”. I left for the land of warmth and vitamin C(维生素C), thinking of beaches and orange trees. When we touched down to blue skies and warm air, I sent up a small prayer of gratefulness. Swimming pools, wine tasting, and pink sunsets(at normal evening hours, not 4 in the afternoon) filled the weekend, but the best part- particularly to my taste, dulled by months of cold- weather root vegetables- was a 7 a.m. adventure to the Sarasota farmers’ market that proved to be more than worth the early wake-up call.
The market, which was founded in 1979, sets up its tents every Saturday from 7:00 am to 1 p.m, rain or shine, along North Lemon and State streets. Baskets of perfect red strawberries, the red-painted sides of the Java Dawg coffee truck; and most of all, the tomatoes: amazing, large, soft and round red tomatoes.
Disappointed by many a broken, vine-ripened(蔓上成熟的) promise, I’ve refused to buy winter tomatoes for years. No matter how attractive they look in the store, once I get them home they’re unfailingly dry, hard, and tasteless. But I homed in, with uncertainty, on one particular table at the Brown’s Grove Farm’s stand, full of fresh and soft tomatoes the size of my fist. These were the real deal- and at that moment, I realized that the best part of Sarasota in winter was going to be eating things that back home in New York I wouldn’t be experiencing again for months.
Delighted as I was by the tomatoes in sight, my happiness deepened when I learned that Brown’s Grove Farm is one of the suppliers for Jack Dusty, a newly opened restaurant at the Sarasota Ritz Carlton, where- luckily for me- I was planning to have dinner that very night. Without even seeing the menu, I knew I’d be ordering every tomato on it.What did the author think of her winter life in New York?

Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I’ve ever had: Be bold and brave — and mighty (强大的) forces will come to your aid.
Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.
Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas — even physical strength greater than most of us realize.
Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet（子弹） — and stopped him cold.”
Boldness — a willingness to extend yourself to the extreme—is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.
So, always try to live a little bit beyond your abilities—and you’ll find your abilities are greater than you ever dreamed.Why was the author sometimes unable to reach his goal in the past?
| A．He faced huge risks. |
| B．He lacked mighty forces. |
| C．Fear prevented him from trying. |
| D．Failure blocked his way to success. |
What is the implied meaning of the underlined part?
| A．Swallow more than you can digest. |
| B．Act slightly above your abilities. |
| C．Develop more mysterious powers. |
| D．Learn to make creative decisions. |
What was especially important for Tim’s successful defense in the football game?
| A．His physical strength. |
| B．His basic skill. |
| C．His real fear. |
| D．His spiritual force. |
What can be learned from Paragraph 5?
| A．Confidence grows more rapidly in adults. |
| B．Trying without success is meaningless. |
| C．Repeated failure creates a better life. |
| D．Boldness can be gained little by little. |
What is the author’s purpose in writing this passage?
| A．To encourage people to be courageous. |
| B．To advise people to build up physical power. |
| C．To tell people the ways to guarantee success. |
| D．To recommend people to develop more abilities. |
One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem - inability to read.
In the library, I found my way into the "Children's Room." I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.
There on the book's cover was a beagle which looked identical（相同的） to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.
Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.
My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.
I never told my mother about my "miraculous" (奇迹般地) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.

Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.
While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.
The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.
Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.
Fellow Robots is one company bringing social robots to the market. The company’s “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.
The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.How are social robots different from household robots?
| A．They can control their emotions. |
| B．They are more like humans. |
| C．They do the normal housework. |
| D．They respond to users more slowly. |
What can a Jibo robot do according to Paragraph 3?
| A．Communicate with you and perform operations. |
| B．Answer your questions and make requests. |
| C．Take your family pictures and deliver milk. |
| D．Obey your orders and remind you to take pills. |
What can Oshbot work as?
| A．A language teacher. | B．A tour guide. |
| C．A shop assistant. | D．A private nurse. |
We can learn from the last paragraph that social robots will ______.
| A．train employees |
| B．be our workmates |
| C．improve technologies |
| D．take the place of workers |
What does the passage mainly present?
| A．A new design idea of household robots. |
| B．Marketing strategies for social robots. |
| C．Information on household robots. |
| D．An introduction to social robots. |
