Q: Article: Language-learners who say they never or hardly ever use dictionaries often speak English well but usually write poorly, because they make many mistakes. The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. So they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations   of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English. The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, or divide it into syllables  , they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check these in a dictionary. Question: Students who never use dictionary speak well but write poor, because  _ Yes or no, is the answer "They may make mistakes."?
A: No


Q: Article: Security--for the information on your smartphone, as well as for the phone itself---is a hot topic these days. The truth is that you're packing a lot of sensitive information on your phone, and you should keep it safe. When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on the map. You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data. Android does not have an exact equivalent , but there are plenty of alternatives. A free app called Lookout offers the find-my-phone feature. The paid version allows you to wipe the data from your phone remotely. Then there is your coffee shop's WiFi network. Anyone with minimal technical expert skill can snoop on  people using shared wireless networks, harvesting passwords and other personal data. Lookout's apps will caution you when you've logged on to an insecure network, but cannot protect you once you're there. In order to protect yourself on such networks, you can use a virtual private network, or V.P.N. This turns all your activity into nonsense to anyone trying to read along with you from across the Starbucks. It also keeps websites from tracking you and, if you're traveling, allows you to get access to sites that may be blocked in other countries. If you have an iPhone, the simplest V.P.N. app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing  , as opposed to other V.P.N. apps that require you to start them up manually . This matters, because even if you decide you want a V.P.N. app, you want to spend approximately zero time thinking about it. For the most part, _ was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning. I found myself having to turn the app on and off sometimes, which involved setting my phone constantly. If... Question: Which of the following can warn you against the insecure network? Yes or no, is the answer "Lookout"?
A: No


Q: Article: It was an extremely hot day. My younger brother Walt and I had decided to go swimming in the stream behind Mr Blickez's house, because it would be the only way to cool ourselves down. Across his farm and through some woods was a deep swimming hole supplied by several cold springs . The only problem with our plan was that this farm was guarded by a huge mean Hereford bull . Mr Blickez had told us that Elsie, the animal's name, was the meanest bull in town, maybe even the county, and we believed in him. But the hotter it got, the more we thought there was reason to doubt about what he said. For one thing, we remembered Mr Blickez liked telling tall tales; for another, Elsie seemed like a strange name for a bull. Finally, I talked Mom into asking permission for us to walk through the farm, and Mr Blickez finally agreed. On our way across the farm, we stopped at the fence to admire the swimming hole. The sun shone brightly across the cool waters. We couldn't wait to get there. Suddenly, Walt shouted loudly. Elsie had run to him and was licking  his back. I immediately hid under the fence. However, when I looked up, I saw that Elsie wasn't a big mean bull at all. She was just a friendly young cow, and she was going to keep licking my brother's back as long as he stood still. When we discovered the truth, we were so happy. We then ran to the swimming hole and jumped in. The water was just as wonderful as we had dreamed. After that day, we had many good days and we often visited our secret swimming hole guarded by the so-called "big mean bull". Question: What can we know about Mr Blickez? Yes or no, is the answer "He often tells lies."?
A: Yes


Q: Article: Thick dust rose and a large building collapsed. This was the scene in Zhu Zhou,Hunan Province on May 17. Nine people were killed and 16 injured. Things were similar in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them? People are always _ to find a way of preventing buildings' collapse. Better materials and technology help,but they are not a solution. Just like humans,a building has its own life cycle from "birth" to "death".If we know when a building is going to collapse,we can repair it in advance or get out of it before it falls. Now,scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports. The research was led by Nancy Sottos,a professor at the university's Beckman Institute,and Douglas Davis,a graduate research assistant. The secret behind the color--changing material is a type of molecule  .A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle,holding hands. Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule. If one person lets go of his or her hands,the molecule changes color. The research team put the molecule into a soft material. When the researchers stretched the material,it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red. The major problem is that light can get rid of the red color. When the team shone bright light on the molecule,the broken bond was fixed,and the color disappeared. Scientists have yet to do more research before the color--changing molecules can be used outside the lab. Question: Which of the following is a WRONG statement? Yes or no, is the answer "A new material has been applied to buildings to warn people of collapse."?
