If we observe carefully, we van find that most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census(普查)to colours of more than four thousand kinds of flowers and discovered that only eight of them are black. Why?
As we know, sunlight is formed by seven different kinds of coloured light. The wave length of each light changes, so the quantity of heat in each light changes, too. Flowers, especially their petals(花瓣), are very delicate(纤弱) and prone(易于) to the harm caused by high temperature. Black flowers can take in all the light waves, which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.
That is why red, orange and yellow flowers are very common in nature while black flowers are so rare. We can hardly find black flowers because _____.
| A．they are so weak that it’s difficult for them to grow up |
| B．there are no black flowers in the world. |
| C．the petals of black flowers are very delicate |
| D．they can take in the light of all wave lengths, which make the flowers dry up |
Sunlight is formed by _____.
| A．many different kinds of coloured light |
| B．three different kinds of coloured light—red, orange and yellow |
| C．seven different kinds of coloured light |
| D．four thousand kinds of coloured light |
The red, orange or yellow light contains _____.
| A．less heat than the other lights | B．more heat than the other lights |
| C．a great deal of heat | D．a little heat |
“It is a chance in a million” means_____________
| A．it is common | B．it is extremely rare | C．it’s lucky | D．it’s impossible |
“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper radio and television ads, promising good shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA (Food Drug Administration) can require proof under the Food, Drug and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律诉讼), and new devices appear continually, Before buying, it is up to the consumer to judge the safety or effectiveness of such items.It can be inferred that ads mentioned in the text are_____.
| A．objective | B．costly |
| C．unbelievable | D．illegal |
The Relaxacisor is mentioned as______.
| A．a product which was designed to produce electricity |
| B．a successful advertisement of a beauty product |
| C．an example of a quality beauty product |
| D．a product whose distributor was involved in a legal case |
The author intends to______.
| A．make consumers aware of the promoters’ false promise |
| B．show the weakness of the law on product safety |
| C．give advice on how to keep young and beautiful |
| D．introduce the organization of FDA |
Which of the following is true according to the text?
A. The court is in charge of removing dangerous products.
B. The promoters usually just care about profits.
C. New products are more likely to be questionable.
D. The production of a device must be approved by FDA.
More college graduates in China are seeking for work experience instead of advanced degrees, a survey shows. The practical approach, coupled with a record number of students graduating from college, is expected to strengthen competition in the job market, analysts said.
More than 76 percent of university students said they wanted to work after earning their degrees this summer, up from 68.5 percent in 2012 and 73.6 percent last year, according to poll results from Zhaopin.com, a major online agency, Zhu Bo.
The annual survey also shows that about 20 percent university graduates chose to further education after graduation, while about 3 percent wanted to start their own businesses.

When looking at Western Europe，we don’t usually think about poverty—but in fact，some people in modern—day Britain are so hard up that they can’t afford to buy food．
Back in 2008,the financial crisis caused a lot of unemployment．Then there were the cuts to the welfare system in 2013 which added to the problem—and many British people fell into debt．It’s estimated that 500，000 people in the UK have turned to food banks，just to get by．
Steph Hagen，who works in a Nottingham food bank，says, “People do not go to a food bank because it's an open door．It’s a case where they go to it because they need to．With our food bank—we are an independent one．and we have limited stocks—everyone who comes through our door has no income．”
There are checks to make sure nobody is abusing the system．If a doctor or a social worker thinks someone needs to use a food bank—even for a short time—they can give them vouchers(凭证)．Then the people in need take them along to the food bank and they get handouts for three days．
Churches and individual donors provide most of the food in the banks．But some businesses might help out too．
And what sort of food is offered in food banks? Hagen says, “Basically，we’ve got porridge．We do occasionally get fresh produce but it’s very rare，especially in the winter months．It’s like tinned fruit，tinned ready meals．We have to give out ‘no-cooking’ food parcels because people can’t afford the gas and electricity”．
Community spirit has a lot to do with food banks．Volunteers say they are a great meeting place for people who are lonely and depressed．And when facing a crisis，some beneficiaries might need to feed not only their belly—but also their soul．According to the text，the food bank is a place_____．

| A．Poor people have no money for gas and electricity． |
| B．The volunteers hate to supply cooked food． |
| C．Food banks can’t afford cooked food． |
| D．This kind of food is easy to store． |

Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever- increasing number of cars on the roads. But scientists and students at the CATT, at the University of Maryland are working to solve this problem. They are using simulation(模拟) technologies to help government and private business control and react to changing traffic conditions.
The online economics magazineForbes.comsays traffic congestion(拥挤) cost Americans $ 124 billion in 2014 and that number could rise to $ 186 billion by 2030.
Bui scientists at the CATT lab are trying to reduce those costs. They are developing a system that helps traffic managers. planners, emergency workers and businesses plan and react better. Michael Pack is CATT director. He says the system is important to help emergency workers, or first responders，reach an accident area faster.
The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones.
About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times. They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called "visualizations". These visual representations help emergency workers better understand what is happening.
The center shares its findings with firefighters, police，Transportation departments and the military. They also share information with universities and transportation company. The technology company Google uses the data for its traffic-related websites. Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly.
Mr. Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.The second paragraph is written to
