Article: In China ,with the development of society, more and more people are annoyed at the continually rising house prices. They want to know who is to blame for it. Local governments,developers and speculators share a vested interest in it. People who are really in need of homes are most likely to suffer heavy losses. Many local governments depend on selling land to keep its normal operation. The higher land prices,the more money. Therefore,developers back the local governments by buying land at high prices. In return,the governments make favorable policies to help the developers. For example,drive all the possible home buyers to this nasty market. They even encourage large numbers of speculators to catch more people. Rising house prices have already become the fence which divides the Chinese society. It has caused widespread dissatisfaction. The government will lose the support of the common people if leaving house prices out of control. Besides,rising house prices will stop us building the new countryside as the present policy actually forbid people to flow freely from cities to the countryside. Collecting taxes on houses can fundamentally solve this problem. On one hand,it will discourage the speculators. On the other hand,it will offer a stable tax resource apart from reducing the sales cost of the developers. secondly,stop the developers selling the houses before completion. If so,the developers will certainly try their best to sell all their houses once completed. And this will also lower speculators' expectation of price rising,which will decrease speculations.
Answer: speculators
The only victims of rising house prices are _ .

Article: Boy's schools are the perfect place to teach young men to express their emotions and involve them in activities such as art dance and music. Far from the traditional image of a culture of aggressive masculinity , the absence of girls gives boys the chance to develop without pressure to agree with a stereotype, a US study says. Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to agree with the "boy code"of hiding their emotions to be a "real man". The report, presented at a conference of the International Boys'Schools Coalition in London attended by the heads of private and state schools, goes against _ that boys do better when taught alongside girls. Tony little, headmaster of Eton, warned that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls. The research argued that boys often perform badly in mixed schools because they become discouraged when their females peers do better earlier in speaking and reading skills. But in single-sex schools teachers can tailor lessons to boy's learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James, of the University of Virginia. Teachers could encourage boys to enjoy reading and writing with "boy-focused"approaches such as themes and characters that interest them. Because boys generally have more acute(sharp)vision, learn best through touch, and are physically more active, they need to be given "hands-on"lessons where they are allowed to walk around. "Boys in mixed schools view classical music as feminine and prefer the modern type in which violence and sexism are major themes" James wrote. Single-sex education also made it less likely that boys would feel they had to agree with a stereotype that men should be "masterful and in charge" in relationships, "In mixed schools boys feel forced to act like men before they understand themselves well enough to know what that means." The study reported.
Answer: naturally stress in boys the traditional image of a man
In the eyes of the author, a single-sex school would _ .

Article: Astronomers have captured the first direct image of a planet being born. Adam Kraus, of the University of Hawaii's Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth. The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago. Called LkCa 15b, it's the youngest planet ever observed. The previous record holder was about five times older. Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA's Goddard Space Flight Center in Maryland. Observing planets while they're forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away. Planets can change orbits after forming, so it's difficult to answer such questions by studying older planets. "These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now," Kraus said. Scientists hadn't been able to see such young planets before because the stars they're circling around outshine them. Kraus and Ireland used two techniques to overcome this problem.[:++] One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion created by the Earth's atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star. The star LkCa 15--the planet is named after its star--was the team's second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.
Answer: know the relationship between planets and their stars
The research on younger planets helps scientists _ .
