I'm taking a test and have to guess the right answer to the question after the article. Article: Perhaps you do not know your school principal well . But you might be wise to take him or her seriously . Beijing University will enroll students recommended by high school principals this year . If the students recommended pass the interviews by Beijing University , they will have 30 extra points added to their national college entrance exam scores if they want to apply to the university. Beijing University said the reason was a desire to give students with comprehensive or special abilities a chance to stand out . However , a survey showed 10,046 out of 14,227 people are against the measure . Some experts agree to the criticism . Liu Daoyu , former president of Wuhan University is one strong opponent . " There are so many high schools in China . But only 39 schools are allowed to recommend students ." Is it fair to the rest of the schools in China ? Besides , most of the 39 schools are in big cities , which is more unfair to other regions ." The reform is also unfair to other students , some day . According to Liu , in the competitive exam , one extra point can put a student ahead of a large number of others------never mind 30 . " Principals do not know students well . How can they guarantee the recommendation will be fair ?" asked Wang Xuming , an education expert . The Ministry of Education said the move is a good experiment in college admission reforms and the public should support it even if it is not yet mature . It said Beijing University promised a series of supervision measures to avoid cheating . For example , the information of schools and principals that recommend students , and the recommended students will be put online for a week for public supervision . Question: The following are the reasons why Liu Daoyu is against Beijing University's reform EXCEPT that _ - Options: A: there will be a lot of cheating B: it is unfair to the other regions C: it is unfair to other schools D: 30 points cause a huge gap among students

I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists have created a way to control a robot with signals from human brain.By generating the proper brainwaves--picked up by a cap with electrodes that sense the signals and reflect a person's instructions--scientists can instruct a humanoid robot to move to specific locations and pick up certain objects. The commands are limited to moving forward,picking up one of two objects and bringing it to one of two locations.The researchers have achieved 94 percent accuracy between the thought commands and the robot's movements. "This is really a proofofconcept demonstration," said Rajesh Rao,a researcher from the University of Washington who leads the project."It suggests that one day we might be able to use semiautonomous robots for such jobs as helping disabled people or performing routine tasks in a person's home." The person wearing the electrode cap watches the robot's movements on a computer screen through two cameras installed on and above the robot. When the robot's cameras see the objects that are to be picked up they pass on the information to the user's computer screen.Each object lights up randomly on the computer screen.When a person wants something picked up and it happens to light up,the brain registers surprise and sends this brain activity to the computer and then to the robot.The robot then proceeds to pick up the object. A similar algorithm is used to decide where the robot will go. "One of the important things about this demonstration is that we're using a 'noisy' brain signal to control the robot," Rao said."That means we can only obtain brain signals indirectly from sensors on the surface of the head,not where they are generated deep in the brain.As a result,the user can only generate highlevel commands such as indicating which object to pick up or which location to go to,and the robot needs to be autonomous enough to be able to execute such commands." In the future,the researchers hope to make the robots more adaptive to the environment by having them carry out more complex commands. Question: What Rao said suggests that the new robot _ . Options: A: is still at its early stage of development B: will be widely used in our daily routine soon C: is autonomous enough to complete complex commands D: is only limited to doing routine work at home

I'm taking a test and have to guess the right answer to the question after the article. Article: Life is not easy in senior high school. You've got the pressure of studies and exams. From time to time, you may feel depressed and frustrated. When depression strikes, you have to take measures to fight it. One of the strangest ways to fight depression is to eat salt, scientists have found. Salt acts as a natural anti-depressant , researchers say. While too much can lead to high blood pressure and heart disease, not enough can cause "psychological depressions", a study has reported. The study, by researchers at the University of Iowa in the US, discovered that when rats are _ in salt, they don't do activities they normally enjoy. The recommended daily salt intake for an adult is four grams, although experts say the body needs only half as much. However, most adults in the developed world consume around ten grams a day, mainly because their diets contain high salt amounts. Today, 77 percent of US salt intake comes from processed and restaurant foods, like frozen dinners and fast food. The minerals in salt are required by the body--in small quantities--to help move liquid in and out of cells. But too much can cause diseases, for example high blood pressure. Today scientists are finding that salt is an addictive substance--almost like a drug. One sign of addiction is using a substance even when it's known to be harmful. Many people are told to eat less salt due to health concerns, but they have trouble doing so because they like the taste and find low-salt foods tasteless. Humans have a long history of eating salt. In the Stone Age, people didn't need to find salt, because they hunted most of their food, and ate a lot of red meat, which has plenty of salt in it. But when people began to farm, about 10,000 BC, they started to eat mainly grains like rice and wheat, and very little meat. Then they had to find another way to get salt. Question: Which of the following statements is true? Options: A: People have trouble reducing salt because they don't know it is harmful toeat too much of it. B: Before 10,000 BC, human beings did not need salt. C: The richer the country is, the more salt is eaten there. D: Taking more than 4 grams of salt a day can be harmful for an adult's health.
