Article: Pictures That Don't Last "YEARS ago when I was at the Grand Canyon, I remember someone coming up to the canyon's edge, taking a shot with their camera and then walking away, like 'got it - done', barely even glancing at the magnificent scene sprawling in front of them," Linda Henkel, a scientist at Fairfield University, US told Live Science. Henkel was surprised by how obsessed people are with taking pictures these days - before dinner, during friends' birthday parties, on museum tours and so on.You know people just like that, don't you? They keep taking pictures because they think that it helps record the moment, but as Henkel's latest study has just found out, this obsession may prevent their brains from remembering what actually happened, reported The Guardian. In her study, Henkel led a group of college students around a museum and asked them to simply observe 15 objects and to photograph 15 others.The next day the students' memory of the tour was tested, and the results showed that they were less accurate in recognizing the objects and they remembered fewer details about them if they photographed them. "When people rely on technology to remember for them - counting on the camera to record the event and thus not needing to attend to it fully themselves, it can have a negative effect on how well they remember their experiences," Henkel explained. But there is also an exception: if students zoomed in to photograph part of an object, their memory actually improved, and those who focused the lens on a specific area could even recall parts that weren't in the frame. So basically, this study is saying that constantly taking pictures can harm your memory.But shouldn't reviewing pictures we have taken help wake up our memories? This is true, but only if we spend enough time doing it. "In order to remember, we have to access and interact with the photos, rather than just amassing them," Henkel told The Telegraph.However, previous research has shown that most people never take the time to look over their...

Read the following article and answer the question. Article: Trains have long been an important form of transportation. Yet they have changed a lot since 1804, when the first train moved at 8 km/hr. Today's high speed trains can go 300 km/hr or faster. Besides their speed, they have many advantages over other transportation types. Japan built the world's first high speed railway. In 1964, Japan's "Shinkansen" trains started traveling between Osaka and Tokyo at 200 km/hr. Over time, more lines, as well as faster trains, were built. Korea, England, and the USA, now have their own high speed systems. Taiwan Province's started running in 2007. Its trains are based on two types of Shinkansen trains. They can carry 989 people and travel from Taipei to Kaohsiung in less than two hours. These systems are expensive to build, but they have many advantages. For example, they are good for the environment. Trains on the London to Paris line create 1/10 the pollution that planes create. High speed trains are also safer and cleaner than cars. Super fast trains can even help a country's economy . They make it easier to travel to faraway places. That helps businesses and land values in those areas. It's no wonder so many countries are building their own high speed railways. Question: One of the disadvantages of high speed trains mentioned in this passage is that _ . Answer:

OPTIONS:
- they are safer than some other transportation types
- it costs a lot to build the whole high speed systems
- they're good for a country's businesses and land values
- super fast trains can help a country's economy

Answer: it costs a lot to build the whole high speed systems

Problem: OPTIONS:
- do sports
- guess the new words
- study well
- play music
Q: Read the following article and answer the question. Article: All students need to have good study habits . When you have good study habits, you learn things quickly. You also remember them easily. Do you like to study in the living room ? This is not a good place because it is usually too noisy. You need to study in a quiet place, like your bedroom. A quiet place will help you only to think about one thing. When you study, do not think about other things at the same time, only think about your homework. If you do so, you will do your homework more quickly, and you will make fewer mistakes. Good study habits are very important. If you don't have them, try to learn them. If you have them , try to make them better. Question: The writer tells us how to _ . Answer:
Answer: study well

Read the following article and answer the question. Article: What's going to happen in the future? Will robots control our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen in 10 to 30 years from now, according to the BBC.2-1-c-n-j-y Digital money We used to pay with cash for everything we bought. Now when we use a credit card to shop online, money is spent without us seeing it. That means we are already using digital money. Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash. When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. It's reported that people in Sweden completely stopped using cash last year, and the US might be next. Bionic eye It's no longer something only in a science fiction movie. People who are blind may have a chance to get their sight back--by wearing bionic eyes. A blind eye can no longer sense light, but a bionic eye can use a camera to "see" the environment and send data to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A high resolution image could be just a few years away. Self-driving cars Unlike a human driver, a self-driving car won't get distracted by phone call, the radio or something outside the window. Sensors and cameras on the car would allow it to stick reduce the number of road accidents. You could even take a nap while the car driver itself. Many vehicle companies are now planning self!driving cars. "By 2040, driverless vehicles will be widely accepted and possibly be the dominant vehicles on the road," said Jeffrey Miller, professor at the University of Alaska Anchorage, US. Question: Which of the following can be predicted from the passage? Answer:
OPTIONS:
- There would be a number of self-driving
- The blind could use cameras to see things around.
- We would live a hard life with digital money.
- Robots would control the world.

Answer:
There would be a number of self-driving
