Ever since news of widespread food recalls caused by a carcinogenic dye broke, there has been confusion（混淆） over possible links to the country of the same name, but Sudan officials say there is no connection whatever.
Sudan1 is a red industrial dye that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003.
Since the ban was put in place, EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled.
Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the dye’s name.
Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.
"We want to keep an eye on every detail and avoid any misunderstanding there," she said. "Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country. But they told us there was no relationship."
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week.
"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said. "People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out."
Sudan dyes, which include Sudan1 to 4, are red dyes（颜料） used for colouring solvents（溶剂）, oils, waxes, petrol, and shoe and floor polishes. They are classified as carcinogens by the International Agency for Research on Cancer. What does the underlined word mean in paragraph one?
| A．Causing cancer. | B．Having side effect. | C．Containing poison. | D．Poisonous. |
How did the Sudan1 get its name?
| A．The dye is often produced in Sudan. |
| B．The dye has something to do with the country named Sudan. |
| C．Nobody is sure of the origin of the name. |
| D．Many foods produced in Sudan contain the dye. |
We can infer from the passage that.
| A．the Sudan government is paying much attention to the food safety |
| B．Sudan1 is often used to be added to the food |
| C．people didn’t realize the danger of Sudan1 until 2003 |
| D．many food shops will be closed down |
Which of the following is the best title?
| A．Keep away from Sudan1 |
| B．No Sudan1 dye links to the country |
| C．How Sudan1 dye got its name? |
| D．Pay attention to the food safety |
Sixty-five million years ago, an asteroid (小行星) that crashed on Earth led to the disappearance of the largest animals that have ever walked our planet – the dinosaurs. At least, this is what some scientists believe. But that accident happened so long ago. People have come to believe that we are free of threats from asteroids and everything else from space.
However, what happened on Feb 15 , 2013 was a reminder that we’re just as vulnerable as the dinosaurs once were. Two objects from space – a meteor (陨石) and an asteroid called 2012 DA14 – visited Earth’s atmosphere on the same day. The former fell in Russia, injuring 1,200 people, while the latter passed by Earth at a record-setting close distance.
Scientists had been expecting the asteroid since last year, but the meteor was a surprise. NASA’s telescope system only detects asteroids at least 50 meters in diameter (直径), which is just about the size of 2012 DA14. But the meteor was much smaller, which made it harder to spot.
But what if we do spot an asteroid that is headed right for Earth? There are several possible ways in which dangerous asteroids could be made to change its orbit. Which method is best depends on several factors and most importantly – how much time we have to stop it.
If there is enough time before the hit, we can send off a heavy spacecraft to travel alongside the asteroid. The gravity from the spacecraft would gradually change the rock’s orbit. Besides that, scientists could one day use sun-powered lasers to either make asteroids disappear or change their course. If there’s not enough time, we’ll have to go after the asteroid with a spacecraft and change its orbit with a crash. Finally, if things are truly desperate, there will be only one choice left – to use a nuclear bomb. That could turn the asteroid into a meteor shower, which would be even more dangerous.The author mentioned the asteroid that led to the dinosaurs’ dying out to ______.

When someone says “SHARK” most people think of a big, toothy, underwater animal; basically we are imagining a Great White. In fact sharks come in all shapes, sizes and even colors! Follow me please; I’d like to show you a very special small shark commonly known as horn sharks, only found in the coastal waters of north-west North America.
Look at this shark, and you can easily see the horns on it and you will know the reason why it is called the horn shark is that it has the broad, flattened head and two large horn-like spines(脊椎) found behind its eyes and makes it one of the hardiest of all shark species. What makes it unique is that as its enemy attempts to swallow it, the spines on its back will stick into the enemy’s mouth and give a good chance for it to get away.
The horn shark is brown in color with black spots all over its body. The adults can reach up to a length of 4 feet and weigh up to 10 kg. An interesting fact about the horn shark is that it has five gills(鳃). The horn shark is a clumsy swimmer using its flexible pectoral fins(胸鳍)to push itself along the bottom of the ocean. The maximum distance that has ever been recorded for a horn shark to have traveled out from its habitat is 10 miles.
Today, as so little is known about its population off the Californian coast, they have been listed as being “Data Deficient” in the World Conservation Union. The horn shark is being threatened both by water pollution and commercial fishing in the area. Though they are not among those sea creatures hunted primarily for food, but they often get caught as a by-catch in fishing expeditions. The horn shark gets its name for______.
| A．its small size | B．its large eyes |
| C．its two large spines | D．its brown color with spots |
How is paragraph 3 mainly developed?
| A．By giving descriptions | B．By following time order |
| C．By analyzing causes | D．By making comparisons |
Which factors contribute to the horn shark’s being on the “Data Deficient” list?
①That people like hunting them for pets ②That people fish them for fun
③Water pollution off the coast ④Knowing little about them
| A．①② | B．②③ | C．①④ | D．③④ |
According to the passage, all of the following are unique to the horn shark EXCEPT that_____.
| A．it doesn’t travel far |
| B．it is good at swimming |
| C．its spines can be used to attack the enemy and escape |
| D．it is only found in the coastal waters of north-west North America |
DEAR AMY: Last year I got a full-time job as a baby-sitter for a wonderful family with two amazing kids. They have come to treat me as one of their own. But my boyfriend and I are attempting to save much more money for the life we want to build, including marriage, a house and kids. Much as I love my “babies,” I’m looking forward to beginning a challenging career in a big company. Should I tell the family that I am looking for a new job? I don’t want to find one that requires me to begin work immediately, leaving them without child care, but I also don’t want them to assume that I’m leaving right away.

In which column of a newspaper can we probably find the passage?
| A．Jobs | B．culture | C．Life | D．Entertainment |
Many businesses today use conferences as a means of discussing new plans of the company. As people are paying more attention to the environment and green problems, more businesses are looking for ways to reduce their negative effect on the environment. Many businesses do this by using web conferencing.
Web conferencing is a technology that allows people to communicate more effectively over the Internet. It is an easy way of hosting and attending conferences without having to leave the office. Each of the people involved in a web conference will be posted an invitation to the conference with the time and date of the Web conference on it. When the conference is ready to begin, all participants (参与者) must sit at their computers and they will be connected over the Internet.
With Web conferencing all participants attend the conference from the comfort of their own desk. Obviously, in doing this no fuel is used in traveling to and from a conference, and less work time is taken up in attending a conference.
Any material to be used during the Web conference is simply e-mailed to all the participants before the conference. Participants can then either choose to print material or read it on screen. This not only saves paper but also greatly reduces mailing cost for the business.
As a conference hall or business center isn’t being used, it means that the only power that is used is the power used by the participants’ personal computers. Similarly conference organizers don’t have to arrange for food or overnight accommodation (住宿) for participants of their conferences. All this means that less energy is used.
Often in business some companies actively choose to do business with other companies that do many things to reduce their negative impact on the environment. And Web conferencing helps you show other businesses that you are willing to work hard for the green cause.
So Web conferencing is much cheaper and greener and more people are willing to host and attend a web conference.What is the passage mainly about?
A. Ways of protecting the environment.
B. B. Green benefits of Web conference.
C. Ways of hosting a Web conference.
D. Impacts of Web conferencing on costs.According to paragraph 1, many companies use Web conferencing because they ________.
| A．are interested in using any new technology |
| B．believe that Web conferencing is more convenient |
| C．want to do something to protect the environment |
| D．haven’t enough money to hold a traditional conference |
The participants of a Web conference_________.
| A．will be e-mailed an invitation before the conference |
| B．are required to sit in the office together |
| C．will receive many paper materials |
| D．must have access to the Internet |
Which of the following words best describes the author’s opinion about a Web conference?
| A．Useless. | B．Environmentally friendly. |
| C．Inconvenient. | D．Money-consuming. |
