    Scientists have found an unexpected use for virtual reality headsets (耳机). The devices (装置), widely used by computer gamers, show pictures that can be used to test the navigational (导航的) skills of people, who were thought to be at risk of dementia (痴呆). Those who do worse in the tests will be the ones more likely to develop Alzheimer's disease later in life, scientists now believe.

    The discovery that the loss of navigational skills was associated with Alzheimer's was made several years ago by Dennis Chan and his colleagues based at several centers in the UK. These studies used computers to test navigational tasks. But now scientists plan to take their tests to a new level with the use of the virtual reality headsets in which wearers are placed in man-made environments through which they must navigate.

    Around 300 people, aged between 40 and 60, will be arranged to participate in the study. Some will have a gene that puts them at risk of the condition or will come from a family with a history of Alzheimer's. Not all will certainly be affected by the disease, however. Chan's project aims to find out who will. Wearing the headsets, participants will be asked to navigate their way through a series of different environments and then remember the details.

    Researchers recently pointed out the significance of a tiny area of the brain known as the entorhinal cortex (an important memory center in the brain). It acts as a center in a widespread brain network that controls navigation. This now appears to be the first part of the brain that seems to be easily harmed by Alzheimer's.

    The goal of the work is to help people as they develop the disease. "So far, drug trials for Alzheimer's have been applied when people have already got dementia, by which time considerable damage to the brain has already occurred," Chan told the Obsenver. "If we can develop drugs and use them earlier, for example, before the disease has spread beyong the entorhinal cortex, then this would have the potential to prevent the dementia."

(1)、What does the unexpected use of VR headsets mentioned in Paragraph 1 refer to?
A、Making games mor interesting for computer gamers. B、Testing ones potential to develop dementia. C、Helping people suffering Alzheimer's recover. D、Reducing the risk of harming chemicals.
(2)、What are the participants required to do in the study?
A、Know unfamiliar environments by using tablet computers. B、Identify directions in some man-made environments. C、Play computer games by using navigational skills. D、Create special environments by using navigational skills.
(3)、What's implied (暗示) about the entorhinal cortex in the brain?
A、Its functions have becn known for years. B、It can be expanded by using VR headsets. C、It can directly affect one's navigational skills. D、Its size depends on that of ones memory center.
(4)、From Chan's words, we can know ________.
A、he will spread the new drug B、he will try out the drug C、the study helps to prevent dementia D、the study still needs to be improved

    What should we do when we are in a bad situation? Some may choose to give up. But is that what we should do? The following news report may get you encouraged.

    With a population of 156 million, Bangladesh has one of the largest populations in the world. What makes the situation worse is that most of the country is situated on the low-lying Ganges delta(三角洲). As a result, it often suffers flooding, especially during the rainy season from July to October. In this period, the rivers rise as much as 12 feet. In such situations, people can only get to certain places by boat.

    The problems are particularly serious in the Chalanbeel region, a poor area where people survive by farming on the rich delta soil when it is not underwater. But many parents there don't want to send their children to school and there are not enough teachers. As a result, many kids living there do not attend school on a regular basis. The problem becomes worse during the rainy season when land schools cannot be reached. Many students never return to school after the forced breaks.

    How to help students attend school regularly? 22-year-old Bangladeshi architect Mohammed Rezwan decided to take action. In 2002, the young man used $500 he had received in scholarships to start Shidhulai Swanirvar Sangstha. The non-profit organization's mission was to set up floating schools. It took Rezwan four years to raise enough funds to open his first boat school. But as the world began to know about the organization's worthy cause, money started to pour in. Until now, Shidhulai Swanirvar Sangstha has built 22 floating schools, some with playgrounds on the upper deck. Now a lot more children in the Chalanbeel region go to school regularly.

    We should keep in mind that there is always a solution to every problem.

    We were on tour a few summers ago, driving through Chicago, when right outside of the city, we got pulled over(被迫停车). A middle-aged policeman came up to the car and was really being troublesome at first. He said,“ You were speeding. Where are you going in such a hurry?” Our guitarist, Tim, told him that we were on our way to Wisconsin to play a show. Then his way towards us totally changed. He asked, “Oh, so you boys are in a band(乐队)?” We told him that we were. He then asked all the usual band questions about the type of music we played and how long we had been at it.

    Suddenly, he stopped and said, “Tim, you want to get out of this ticket, don't you?” Tim said, “Yes.” So the officer asked him to step out of the car. The rest of us, inside the car, didn't know what to think as we watched the policeman talk to Tim. Then the policeman put Tim in the back of the police car and threw the car into reverse(倒车), stopping a few feet in back of our car.

    Now we suddenly felt frightened. We didn't know if we were all going to prison. Suddenly, the policeman's voice came over in a loudspeaker. He said, “Ladies and gentlemen, for the first time ever, we have Tim here singing on Route 90.” Later we knew, the policeman had told Tim that if he sang one of our songs over the loudspeaker in the police car, we would get out of the ticket. Seconds later, Tim started screaming into the receiver. The policeman enjoyed the performance, and sent us on our way without a ticket.

    Internet slang refers to a variety of slang languages used by different people on the Internet. It is difficult to provide a standardized definition of Internet slang due to the constant changes made to its nature. However, it can be understood to be a type of slang that Internet users have popularized, and in many cases, have coined. Such terms often begin with the purpose of saving keystrokes or to compensate(补偿)for small character limits. Internet slang consists of a number of different ways of speaking, sub-languages, expressions, spelling techniques and idioms that have obtained most of their meaning on the Internet.

    Love it or hate it, there is no escape from Internet slang. It has become popular among the teenagers. Just like US teenagers use “LOL”(laugh out loud) when commenting on a funny video, China's post-00s generation, a group born between 2000 and 2009, like to use “XSWL” (laughing my head off). Acronyms(首字母缩略词) and shortened expressions may be popular as they offer shorter ways of communicating. For teenagers, they could also allow them to communicate in their own way.

    Understanding the most common acronyms and texting symbols can help to decode and decipher any text message, email or instant message online. Here are some of the most popular symbols, abbreviations, and acronyms you are likely to stumble upon when texting or receiving messages and chatting on line. OMG: Oh my God; BRT: Be right there; TTYL: Talk to you later; JK: Just kidding; G2G: Got to go; NMU: Not much, you? RBAY: Right back at you; IDC: I don't care.

    Some people think that Internet slang affects the language negatively. However, Melbourne University linguist Rosey Billington doesn't agree.

    “When you are able to use language in a creative way, you show you are linguistically knowledgeable because you know the language rules well enough to use words in a different way.”Billington told News.com. Au .Her view is supported by two linguists, Lauren Spradlin and Taylor Jones.
