Concepts from science and nature are filled with our language’s common phrases , idioms and spoken expressions. The unbelieving expression “Well, I’ll be a monkey’s uncle” has its origin in bitter disbelief over Darwin’s writings on evolution. These colourful expressions bring spice(趣味) to our language.
Yet certain well-used phrases from science are just plain wrong! Some are obvious, yet we use them anyhow. For example, a person who acutely shakes her head and says “ A watched pot never boils” while you are waiting second after tiring second for test results to arrive or job offers to come in knows that if she sat down and watched a pot containing water on a stove over high heat for long enough, the water will eventually boil.
However, a few phrases have less obvious scientific inaccuracies. Here are a few for you to consider.
Once in a blue moon: This poetic phrase refers to something that occurs extremely rarely. A blue moon is the term commonly used for a second full moon that occasionally appears in a single month of our solar-based calendars. The problem with the phrase, however, is that blue moons are not so rare. They happen every few years at least, and can even happen within months of each other when the 29.5-day lunar cycle puts the full moon at the beginning of any month but February. The usage of “blue moon” as the second full moon in a month dates back to a 1937 Marine Farmer’s Almanac . But before that, blue moons meant something slightly different. Typically, 12 full moons occur from winter solstice to the next winter solstice, but occasionally a fourth full moon in a season could be observed . In such a case, one of the four full moons in that season was known as “blue”
Where there’s smoke, there’s fire: The phrase means that if something looks wrong, it likely is wrong. But let’s step back. Do you always have to have fire if you see smoke? Answering that first requires defining ‘fire” , Merriam—Webster’s first definition of fire is “ the phenomenon of combustion manifested in light, flame and heat”. Combustion is the chemical reaction that occurs when fuel is burned in the presence of oxygen---denying a fire any of these three things will stop the fire; attempting to start a fire without any one of the three things will be impossible. In complete combustion---what occurs when you light a gas stove--- the fire produces no smoke. However, when most materials are burned, they have incomplete combustion, which means that the fire isn’t able to completely burn all of the fuel . Smoke, then, can be considered to be a product of pyrolysis (高温分解) rather than of fire itself. You’re probably thinking---so what? To get the smoke, a fire needed to be present at some point, right? Not always.
Diamonds are forever: Thanks to the DeBeers slogan , decorating your honey’s neck, wrists and fingers with diamonds means true and timeless love. Of course, no object that you can hold in your hand can last forever. But diamonds have a special reason for being incapable of timelessness. Without the extreme pressures of the deep Earth where they formed, a diamond will slowly turn back into graphite(石墨), which is why the older a diamond is, the more inclusions it’s likely to have.
What common phrases push your buttons when viewed under the microscope of science? Are you curious about the hidden knowledge of some “ big” phrases ? Or perhaps you have the ability to uncover the secret of some unscientific phrases? Let us know!According to the passage, the blue moon _________.
| A．appears at the beginning of a month |

What can be concluded from the passage?
| A．the older a diamond is, the more valuable it’s likely to be. |
| B．Fire is not necessarily causing smoke |
| C．Smoke is a product of complete combustion |
| D．the less obvious scientific inaccuracies of some phrases make them more useful |
The underlined phrase “push your buttons” in the last paragraph means “_______”.
| A．impress you a lot | B．frighten you much. |
| C．surprise you greatly | D．make you lose your interest |
The author’s attitude towards the scientific inaccuracies of the phrases is ________.

| C．critical | D．favourable |
Part-time jobs for 15 and 16 years olds
| Waiter / Waitress A job as a waiter or waitress is a good choice for 16-year-olds. Not only can one earn $9-$12 an hour, but they can also get the tips (小费). Most people that visit a restaurant don’t just have good food. They come here to relax and have a good time. Besides serving food quickly, a young waiter who talks to them politely with a smile on his face will make the diners enjoy their time at the restaurant. |
| Work in a library If one is fond of books, working in a library is another suitable choice. Besides the pay is good, it offers a lot of free time when students can actually sit down and finish their homework. So on returning home, they would have time to hang around with friends or just relax. So working in a library is an excellent part-time job for teens, especially for school students. |
| Internet jobs There are many ways of making money through online jobs like clicking on advertisements, visiting sites and signing up with them. However, such online jobs don’t pay well. A better Internet job for teens is to complete online surveys. These are quite simple surveys that usually ask one about his/ her opinions and ideas. Many companies use these ideas to make products designed for teenagers. |

Four out of ten parents in the UK spend between ￡100 and ￡500 on their children’s birthday parties, according to a survey. Four in ten parents of children under 18, who were questioned in a survey, admitted that they felt pressured into organizing more expensive birthday parties for their children than they would like to.
How much parents spend on their children’s birthday parties is one of the most frequently discussed topics on parenting websites. Here is one comment on Mumsnet summing up the thoughts of many parents: “Where we live everyone hires places, entertainers and so on. I don’t want to compare with my rich neighbors, but I want my son to have what all his classmates have.”
The research was carried out on behalf of the children’s charity, Lumos, set up by the author JK Rowling. Just 13 percent of parents spent ￡50 or less in the past year on their children’s parties.
Many children’s clowns(小丑) or entertainers charge ￡150 or more for an hour, and parents often feel it necessary to book a special place. Even without these, the cost of plates, the cake and party bags can mount up. Party Pieces, a company set up by Carole and Michael Middleton, charge about ￡16 for a birthday cake for a party with 16 guests, ￡22 for table decorations and up to ￡48 for party bags.
Many children of famous people have increasingly expensive parties, often seen in famous magazines. Suri Cruise, the daughter of actor Tom Cruise and actress Katie Holmes, enjoyed a ￡100,000 birthday party according to a report.
Georgette Mulheir of Lumos, said,“Parents in the UK are under increasing pressure to spend more and more money on birthday parties for their children and their children’s friends.”What’s the main idea of this passage?
| A．Children’s birthday parties put their parents under financial pressure in the UK. |
| B．Many parents are willing to spend more on their children’s birthday parties. |
| C．Parents pay more and more attention to their children’s birthday parties. |
| D．Children in the UK hope for more and more expensive birthday parties. |
What does the underlined part “mount up” in Paragraph 4 probably mean?
| A．Increase. | B．Change. | C．Exist. | D．Count. |
By the example of the birthday party for Suri Cruise, the writer probably wants to show that________.
| A．famous people love their children very much |
| B．children of famous people can get whatever they want |
| C．some children of famous people have really expensive birthday parties |
| D．holding expensive birthday parties is common nowadays |
In which of the following sections would you most probably read this passage?

Sydney—A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23．It was the third shark attack along the coast of Australia's largest city in a month．
The 15-year-old boy and his father were in the water off Avalon, on Sydney's northern beaches, around dawn when he was attacked．The city's beaches are packed with locals and tourists during the summer months．

Police said the bites" cut through to the bone" , but the boy did not appear to have sustained any fractures （骨折）．He was in a stable condition now．
Several beaches were closed after the attack．Water police and lifeguards were searching for the shark, while police hoped to identify its species by the shape of the bite marks．But they said it was too early to say what type of shark attacked the boy．"I don't even know if he saw it," Miller said．
Many shark species live in the waters off Sydney's beaches, but attacks on humans are still relatively rare．However, there were two attacks on successive days earlier this month, one on a navy diver in Sydney harbor, not far from the famous Opera House, and the other on a surfer at the city's world-famous Bondi beach．
Fishermen say shark numbers are on the rise．There is a ban on commercial fishing in the harbor, which has increased fish stocks．Marine experts also claim environmental protection has created a cleaner environment, attracting sharks closer to shore as they chase fish．Many shark species, including the Great White—the man-eater made famous in Steven Spielberg's Jaws—are protected in Australian waters．The report mainly tells us _______．
| A．shark attacks on humans are on the rise |
| B．sharks attacked humans three times in one month |

We are all interested in equality, but while some people try to protect the school and examination system in the name of equality, others, still in the name of equality, want only to destroy it.
Any society which is interested in equality of opportunity and standards of achievement must regularly test its pupils. The standards may be changed — no examination is perfect — but to have no tests or examination would mean the end of equality and of standards. There are groups of people who oppose this view and who do not believe either in examinations or in any controls in schools or on teachers. This would mean that everything would depend on luck since every pupil would depend on the efficiency， the values and the purpose of each teacher.
Without examinations, employers will look for employees from the highly respected schools and from families known to them — a form of favoritism will replace equality at the moment. The bright child from an ill-respected school can show certificates to prove he or she is suitable for a job, while the lack of certificate indicates the unsuitability of a dull child attending a well-respected school. This defense of excellence and opportunity would disappear if examinations were taken away, and the bright child from a poor family would be a prisoner of his or her school’s reputation, unable to compete for employment with the child from the favored school.
The opponents（反对者） of the examination system suggest that examinations are an evil force because they show differences between pupils. According to these people, there must be no special, different, academic class. They have even suggested that there should be no form of difference in sport or any other area: all jobs or posts should be filled by unsystematic selection. The selection would be made by people who themselves are probably selected by some computer.The word “favoritism” in paragraph 3 is used to describe the phenomenon that .
| A．bright children also need certificates to get satisfying jobs. |
| B．poor children with certificates are favoured in job markets. |
| C．children from well-respected schools tend to have good jobs. |
| D．children attending ordinary schools achieve great success. |
What would happen if examinations were taken away according to the author?
| A．Schools for bright children would lose their reputation. |
| B．There would be more opportunities and excellence. |
| C．Children from poor families would be able to change their schools. |
| D．Children’s job opportunity would be affected by their school reputation. |
The opponents of the examination system will agree that .
| A．jobs should not be assigned by systematic se lection |
| B．computers should be selected to take over many jobs. |
| C．special classes are necessary to keep the school standards |
| D．schools with academic subjects should be done aw ay with |
The passage mainly focuses on .
| A．schools and certificates | B．examination and equality |
| C．opportunity and employment | D．standards and reputation |
