When many people are worried that there are no more heroes in the modern times, two university students who lost their lives to rescue drowning children have shown that heroes still exist. According to the Inner Mongolia Morning Post, the tragedy   on the afternoon of December 14, 2002 when three school students skating on a frozen lake in Qingcheng Park in Hohhot fell through the ice into the freezing water. More than 20 university students who happened to be near the place where it happened immediately went to the rescue of the children. Two children were quickly rescued, but the third died. The child's body was not found for three hours. Two of the rescuers, Liu Ye and Hao Longbiao, also died of cold and tiredness. The body of Hao who took the lead in jumping into the lake was not found until the next day. A student who was unwilling to tell his name said he and his classmates from the local college were taking photos at the lake. When they heard the children's cries for help, they went to the ice hole hand in hand to rescue the children. But the ice kept breaking, causing most of them to fall into the icy water. Local people held mourning ceremonies   at the lake. Eight of the students were seriously affected by the freezing water and were being kept in hospital for further observation  , but their lives were no longer in danger. The author wrote the passage to    _   . A) warn people of the danger of skating on ice B) ask people to learn from the brave university students C) tell us a tragedy D) advise university students to cherish   their lives
(Answer)

A Japanese company has ordered its employees to get the same hairstyles--- to help save energy. Tokyo-based Maeda Corporation has announced the move as part of a national campaingn to cut energy use. Since Fukushima nuclear plant was destroyed in the earthquake and tsunami that struck Japan in March, 2011, the county's government has asked its people to _ their energy consumption. Men are expected to sport a short back-and-sides, slightly longer on the top, while women have been asked to wear short hair with a fringer   that can be swept to one side. Chizuru Inoue, a spokesman for Maeda Crop, said: "Our company is very devoted to protecting the environment and we encourage our staff to adopt many environment-friendly actions." "We are not sure of the data yet, but we believe if people have short hair they do not need to use their hairdryers for so long and they will use less water. If all our staff do this, then it may save a lot of power." There is another advantage for employees of the construction firm, Ms. Inoue added, as it is easier to make short hair neat again after staff had been wearing hard hats. She said a lot of staff had been calling for information on where they can get their hair cut in the correct style. Following the Fukushima nuclear disaster in March, Japan has been struggling to produce enough electricity for the tsunami ended production at the Fukushima plant. The disaster resulted in a review of the country's energy policy that now means less than a quarter of its remaining nuclear plants are in use. The government has talked about a move away from nuclear energy towards more sustainable   technologies. Many government institutions have taken measures to save power, including a reduced use of air-conditioning in offices and schools. What's the main idea of the text? A) Japan takes steps to protect the environment. B) Japan is moving towards sustainable technologies. C) A Japanese company takes measures to save energy. D) Japan starts a campaign to save energy across the country.

Today we bring you an old tale. It's the story of the three little pigs and the big bad wolf that blew down a house made of straw and one made of sticks. The only house left standing was the one made of bricks. Now there is new evidence to suggest that houses built with bales of straw can be very strong. They are also very environmental. Pete Walker is a professor at the University of Bath in Britain. He and a team of researchers there have built a house made out of straw bales and hemp material. During the next twelve months the team will study the effectiveness of these materials in home building. Professor Walker says there are many good reasons for using straw. Professor Walker: "One of the benefits is it's a relatively inexpensive renewable material that's readily available." He also agrees that straw takes in carbon dioxide as it grows and helps the environment in other ways. So it can be seen as having no harmful effects on the environment. Professor Walker: "The straw bale walls are relatively thick and so all that straw provides very good thermal insulation. So we make buildings that require very little heating in the winter or indeed very little cooling in the summer. So they require very little additional energy." Professor Walker says this reduces home operating expenses. It also reduces the effect on the environment. He says the current interest in straw bale houses is a direct response to the problem of climate change. David Lanfear owns an eco-friendly home building service in the United States called Bale on Bale Construction. He says he laughed when some friends first told him about houses built of straw. But after doing his own research, he learned that building with straw bales made a lot of sense. He has now helped to build more than ten straw bale houses and says the building material is becoming more widely accepted. To build the houses, he fills a wood frame with tightly packed bales of straw. Next he coats the walls inside and out with layers of clay plaster. He says the common ideas... What can we infer from the passage? A) Using straw to build houses is dearer than using bricks. B) The houses built with bales of straw are stronger than those built with bricks. C) Straw which is convenient to get is much cheaper than thick bricks. D) Houses made of bricks are no better than those made of straw.
