Le Whif, an inhaler  that allows chocolate lovers to meet their needs whenever they please without putting on weight, is to be released in British stores. The invention, called the world's first breathable food by its creators, let consumers suck in the taste of chocolate and coffee while taking on less than one calorie. Its makers claim it will enable dieters to enjoy their favorite snacks without worrying about their waistline. The lip-stick-style tube contains hundreds of milligrams of tiny food particles which are small enough to become conveyed by air, but too large to enter the lungs. Each Le Whif contains enough flavor about eight to ten whiffs  and costs $1.99 on its own or $4.99 for a pack of three. The inhaler is available in chocolate, raspberry chocolate and mint chocolate models as well as coffee flavor, which gives a dose of caffeine equivalent to a small short of strong black coffee. It was invented by Prof. David Edwards. He said Le Whif was not designed to replace food but could be used to increase dining experience, such as allowing people to sample a variety of dishes from restaurant menus before ordering their meals He said, "In terms of living off whiffing we aren't even close to being there. But there clearly has been a revolution over the last few years where we are eating smaller amounts of food more frequently, and choosing food or its aesthetic  pleasure. We will be launching new whiffing experiences probably every six months. It is reasonable to assume that the next line of whiffing products will be even more health-centered. The product that was released in Paris in 2009 and the initial production run of 25,000 inhalers were sold out within a month. It has since been made available across France and in the US. In Britain Le Whif is to be sold firstly in House of Fraser for a month, after which it could become more widely distributed. Which of the following statements does David Edwards agree with? A) His new products will come out once a year. B) Le Whif is a revolution that will change people's life completely. C) The whiffing products in the future will be improved. D) Le Whif can make people eat less food.

*Question*
A huge cloud of dust rose and an overpass disappeared. This was the scene in Zhuzhou,Hunan Province on May 17.Nine people were killed and 16 injured. Things were similar last year 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 colorchanging 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. If the bright light keeps the red color from appearing,the material's warning system will be useless. Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab. Which of the following is a WRONG statement? A) Thousands of people died from the collapse of buildings in the Sichuan earthquake because they hadn't been warned. B) There is no building that will never collapse. C) A new material has been applied to buildings to warn people of collapse. D) A colorchanging material can turn red before it breaks.
