Prince Charles yesterday promised to reduce the royal impact on the environment through sweeping changes to his personal lifestyle and official schedule. The prince will replace carbon-heavy private jets and helicopters with scheduled flights and train services.

The move came as Prince Charles urged business leaders to publish the environmental pact of their activities.

He said, “Few accountants and business decision-makers ask, ‘How much of our critical natural resource is left? How many miles of polar ice cap has our business helped melt this year? By how many inches have we raised sea levels? How many species have we put at risk? How many homes will be flooded, how many people will die of thirst or starvation because of our activities? ’ These are not comfortable questions, but, by God, they need to be asked. ”

He added, “At the moment these costs do not appear in anyone’s books… Yet they are real, they are incurred now and in a relatively short time, the damage being caused may be beyond remedy. ” He said the world was “running up the biggest global credit card debt in history, but with little or no thought for how the bill will ever be paid”.

Flanked by the prime minister and business and community leaders at St James’ Palace, the prince said his new “accounting for sustainability” project would give consumers the power to choose products that caused less damage to the planet.

Duchy Originals, the prince’s food company, is taking steps to work out how much carbon dioxide and other green-house gases are emitted in growing, processing and distributing its products. The changes to the prince’s travel arrangements announced yesterday are part of a wider review of the carbon footprint associated with activities at all three of his residences. Clarence House in London, Highgrove and Birkhall on the Balmorals estate(庄园), as well as the activities of his 21 personal and 105 full-time staff. Measures include a review of electricity use, commuter and other staff travel and are intended to identify further reductions in carbon dioxide emissions. The review will report in June , when Clarence House will announce annual targets to reduce carbon emission.

1.How does Prince Charles feel about business leaders in terms of environmental protection?

2.In response to Prince Charles’ calls, Duchy Originals will ______.

Ears are for hearing — everyone knows that. But for a creature called the Cuvier’s beaked whale, hearing starts in the throat (喉咙), a new study found.
The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar (声呐). This sonar, used by some ships, sends out sound waves to locate underwater objects.
The Cuvier’s beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they’re 1,000 meters under the sea, where it is totally dark.
To better understand how the whale hears, researchers from San Diego State University in California took X rays of two Cuvier’s beaked whales. The whales had died and washed up on the beach.
Ted Cranford and his colleagues used the images to make a computer model of a Cuvier’s beaked whale’s head. Then, they modeled the process of sound traveling through the head.
The researchers knew that some sounds get to the ears of a toothed whale through a structure (构造) called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (垫) of fat on the inside.
When the researchers used their computer model to work out how sound waves travel in the whale’s head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal’s jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal’s ears.
【小题1】Toothed whales look for food under the sea by ______.

A.watching the shape and size of their objectsB.diving deep into the sea
C.sending and receiving soundsD.making lots of noises
【小题2】Researchers took X rays of two Cuvier’s beaked whales in order to ______.
A.find out why they had died and washed up on the beach
B.make a computer model of a Cuvier’s beaked whale’s head
C.make sure that sound travels through the head
D.know more about the way the whale hears
【小题3】 Which of the following describes the way taken by sound waves through a Cuvier’s beaked whale?
A.A hole in the back of the jaw → the ears → the jaw → the throat.
B.The jaw → the throat → a hole in the back of the jaw → the ears.
C.The throat → the jaw → the ears → a hole in the back of the jaw.
D.The ears → the throat → a hole in the back of the jaw → the jaw.
【小题4】Which of the following is TRUE according to this passage?
A.The throat is important to the Cuvier’s beaked whale’s hearing.
B.Ships send out sound waves like a Cuvier’s beaked whale.
C.The ears are actually useless to the Cuvier’s beaked whale.
D.The researchers haven’t found how the whales hear.

It is impossible not to make a mistake at some points in your life. We may as well accept that some thing will go wrong and we will be to blame. It is therefore sensible to work out some strategies for apologizing, and the best way to apologize is by letter. This way you can take care over every work you write— which you can’t do if you say sorry to someone in person.

We all say or do something that we wish we hadn’t said or done. You may say something that accidentally hurts someone, or you may provide a service which doesn’t come up to the standards that a client or customer expected.

You may feel that it was a genuine mistake which couldn’t be avoided. Rather than dwell on the mistake, you should quickly try to remedy(修补)the problem. An effective letter of apology is an important part of that process.

For the contents of the letter, just remember TABS—Timing, Action, Brevity, Sincerity.

The timing of a letter of apology is essential—it must be sent as soon as possible. Any delay in our sending the letter will only compound(add to) the problem. In this case “Better late than never” is not the best motto! The longer you wait before you wait before writing a letter of apology, the more it will seem that you have been coerced(被迫)into writing it.

Although it is important to recognize what has gone before, it is also essential to detail the action you plan to take to rectify whatever it was you did wrong. Research has shown that some indication that you have thought about what future action you plan to take is always well received.

A letter of apology should be brief and the word “sorry” should appear no more than twice. Indicate that you are aware using it a second time—“once again, I am so sorry for…” or “as I said earlier, I am really sorry about…”. Finally, the tone of the letter has to be sincere. In fact, the combination of all the above factors will help in this respect.

And don’t think that letters are out of date in the email—oriented 21st century. An apology email can be worse than no apology at all!

72.What kind of advice does the text suggest about apologizing?

A.It’s a good idea to write a letter of apology as soon as something has gone wrong.    

B.It’s a good idea to send several emails to apologize.

C.Write a long letter apologizing several times to make your point.

D.Wait to see how they react to your letter before planning to do anything.

73.What kind of things do you NOT apologize for?

A.A service that is not as good as it should be.

B.Genuine mistakes.

C.Car accidents.

D.Causing offence or hurt.

74.The underlined expression “Rather than dwell on the mistake” in the third paragraph means you _____.

A.should not waste time worrying about what happened.

B.should consider the problem

C.should forget about what happened.

D.should analyse who was at fault.

75.How can timing compound problems?

A.If you write immediately, they will be suspicious.

B.If you leave it for a few days, they will know it is your idea to write.

C.Waiting for a few days before you write will show your sincerity.

D.Waiting too long will make it worse because they won’t believe you mean it.
