For centuries, ships became isolated as soon as they were out of sight of shores and of other ships. This meant that if a ship met with any problems while at sea, they would sink without anyone knowing their fate. This isolation ended up with the invention of the wireless telegraph and Morse code.

By 1904, many transatlantic ships had wireless telegraph on board. Realizing a need for a widely recognized distress call, the letters “CQD” became the first distress call. But at that time different countries used different distress calls.

At the Radio and Telegraphic Conference held in Berlin in 1906, it was noted that there needed to be an internationally agreed upon and recognized signal for distress. No longer should Great Britain use “CQD” while Germany used “SOE”. After much discussion, the letters “SOS” were agreed upon. Although many have later stated that the letters stand for “Save Our Ship”, “Save Our Souls” or “Sink Or Swim”, it is not what the statements mean.

After being agreed upon at the Radio and Telegraphic Conference, the Morse code signal of three dots, three dashes, and then three dots (sent together, without spacing) went into effect as the international signal for distress 2 years later. The letters were chosen because the Morse code of three dots, three dashes, and three dots was easy to recognize and people were able to make as few mistakes as possible when sending it.

Although officially the international signal for distress was “SOS”, many people still used the old signal of “CQD”. Even in 1912, when the Titanic began to sink, its radio operator first sent the “CQD” distress signal. Then another operator suggested also sending the new “SOS” signal. It took several years for “SOS” to replace the old signal.

In Europe people hold the fork in the left hand and the knife in the right throughout the meal, a system that is generally agreed to be more efficient than the American zigzag（曲折的）method. Americans hold both the fork and the knife in their right hands throughout the meal, so they continually change their forks to the left hand when they have to cut their meat. It seems to be funny for the Europeans to see Americans busy changing their dinner sets, making a lot of noises. A few explanations for this American style are as follows:

(1)Americans are practical and efficient. Since most of us are right-handed, it is reasonable to keep our working tools at all times in the right hand that can use them most efficiently.

(2)Americans, the master of the New World are rebels（判逆者).. They use the zigzag method to break the rules in the Old World and in this way they are thumbing their nose at Mother England. Americans are a restless kind. They do not like to sit in one spot for very long when dining.

(3)Forced to do so, they respond by “playing” with the silver.

Whatever the reason for the practice, it is now certainly as American as apple pie. Europeans recognize this and are quick to attack it as evidence of American innocence of form. Arguments against the zigzag method rest not only on grounds of efficiency but also on those of tradition. In Old World Dining, the knife is held in the right hand continually because it can serve as an instant defense against the uninvited intruders. However, such alertness（警觉）is out of place in the New World, as every American believes that this is the home of the brave. Americans juggle their silverware, perhaps, to show that they are not afraid and that one of them holding a fork is worth any number of them holding blades（刀）.

41．Americans use _______ to hold their fork to pick up the salad.

A．the right hand B．the left hand C．both hands D．either of the two hands

42．As the masters of the New World, Americans use a different cutting method from that in the Old World to_____ .

A．show their independence of Mother England

B．show their disrespect to Mother England

C．add a new tradition to those in Mother England

D．show off their creativeness to Mother England

43．In the sentence, the word “juggle” probably means .

A．hold B．play with C．pick up D．lay down

44．Also in the last sentence, the two “them” refer to .

A．Americans B．Europeans

C．Americans and Europeans separately D．Europeans and Americans separately

45.What could be the best title of the text?

A. Old World Dining B. zigzag method

C. New World Dining D. Juggling fork and knife

"The world's oceans are slowly getting more acidic,”say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.

The lowering of the waters’pH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.

Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.

These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change．"This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed（超过）anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid（小行星) impacts．”

However, it is not absolutely clear what that means for ocean life．Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may be more sensitive to pH changes．Coral reefs and other organisms whose shells contain calcium carbonate（小行星) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower pH.

In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming．But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing-because in releasing CO2 into the atmosphere we warm the planet, and when CO2, is absorbed by the ocean, it reduces the amount of greenhouse warming.”

According to Dr Caldeira,__________ .

A. ocean absorption of carbon dioxide is a good thing

B. more oil fuels will be used in the near future

C. scientists may predict climate changes with computer models

D. the future situation of the amount of acidity is extremely serious

f the water's acidity level keeps rising,_________ .

A. ocean life whose structures contain calcium carbonate may be affected

B. the waters’pH value will become higher and higher

C. organisms living near the surface are more sensitive to pH changes

D. some disastrous events will occur more often than before

Most experts once believed storing carbon dioxide in the ocean would reduce________ .

A. the CO2 absorbed by the ocean B. the amount of greenhouse warming

C. the acidity of the ocean D. the gradual release of CO2

The purpose of this passage is to_________ .

A. show people the findings of a research team B. inform people of how acid the ocean is now

C. introduce Dr Caldeira and his team's research D. warn people of the higher level of CO2

Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable jobs. Personal advisors give them better advice for finding jobs. Even judges are softer on attractive defendants. But in the executive（主管的） circle, beauty can become a liability.

　　While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman.

　　Handsome male executives were considered having more honesty than plainer men; effort and ability were thought to lead to their success.

　　Attractive female executives were considered to have less honesty than unattractive ones; their success was connected not with ability but with factors such as luck.

　　All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Interestingly, though, the rise of the unattractive overnight successes was connected more to personal relationships and less to ability than that of the attractive overnight successes.

　　Why are attractive women not thought to be able? An attractive woman is considered to be more feminine has an advantage in traditionally female jobs, but an attractive woman in a traditionally manly position appears to lack the "manly"qualifies required.

　　This is true even in politics, "When the only clue is how he or she looks, people treat men and women differently, " says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates（候选人）. She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women, in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.

　　The results showed that attractive males completely defeated unattractive men, but the women who had ranked most attractive unchangeably received the fewest votes.

　　The word "liability" most probably means ________.

　　A. disadvantage　B. advantage　　　C. misfortune　　 D. trouble

　Bowman's experiment shows that when it comes to politics, attractiveness________

　　A. turns out to　be a disadvantage to men

　　B. is more of a disadvantage than an advantage to women

　　C. has as little effect on men as on women

　　D. affects men and women alike

　　It can be inferred from the passage that people's views on beauty are often________.

　　A. practical　　　B. supportive　　 C. old - fashioned　D. one - sided

　　The author writes this passage to ________.

　　A. give advice to job - seekers who are attractive

　　B. discuss the disadvantages of being attractive

　　C. demand equal rights for women

　　D. state the importance of appearance

For fear of unemployment, almost one million people sat （参加考试）China civil service examination in order to get ________jobs.
