Lucky is the man who has no "skeleton in his closet". When a man has done something in his life that he is ashamed of, that he wants to hide, he is said to have a "skeleton in his closet". Some people may have more than one skeleton.
As we have noted many times, it is hard to find out how these expressions begin. Sometimes, we get some hard facts. But more often we have to depend on guesswork. And that is true of this phrase, which came from England.
Before 1932, English law did not permit a doctor to cut open a dead human body for scientific examination, unless it was the corpse (尸体) of an executed (处决) criminal.
But when it became legal, more and more doctors demanded skeletons for a more scientific study of medicine. It was helping in the advance of modern medicine. The demand had become so strong that men began to rob tombs and sell skeletons to doctors at high prices.
We are told that a doctor would usually buy just one skeleton for scientific study. It became very important in his work. But he had to keep it hidden because most people objected to keeping such a thing. As a rule, the doctor would keep his skeleton in some dark corner where it could not be seen, or hide it in a closet.
After a time, people began to suspect (怀疑) every doctor of hiding a skeleton in the closet. From this suspicion, the phrase "a skeleton in the closet" took on a broader, more general meaning to describe anything that a man wanted to keep others from discovering. It could be proof of a criminal act, or something much less serious. Well, that is one theory.
One writer, however, believes that the phrase might have come from something that really happened. It is his guess that a hidden closet in some old English country home may have turned up a real skeleton, clear proof of some old family shame or crime. Well, one man’s guess is as good as another. But this sounds like a story by the great French novelist, Balzac.
Baizac tells us of a man who suspected his wife of having a lover. The husband comes home by surprise. But she hears him and quickly hides her lover in the closet of her bedroom. He enters her room and asks her if she is hiding her lover. He says he will not open the door to the closet if she promises him there is no one there; He will believe her. She answers firmly that she is not hiding anyone in the closet.
The husband then begins to build a solid brick wall against the closet. His wife watches, knowing that her lover will never come out alive. But she will not change her story and admit her guilt.From the text we know that there are （） theories about how the phrase "skeleton in the closet" came into being.

• A、one

Passage 1
Kimberley Asselin sits in a rocking chair in front of her 22kindergartners, a glistening smile across her face as she greets them for themorning. Even at 9 a.m., she is effervescent and charismatic.
Yet behind Asselin′s bright expression, her enthusiasm is fading.
Asselin,24, is days away from finishing her first year as a teacher, the career of her dreams since shewas a little girl giving arithmetic lessons on a dry-erase board to her stuffed bears and dolls.

While she began the school year in Virginia′s Fairfax County full of optimism, Asselin nowfinds herself, as many young teachers do, questioning her future as an educator. What changed in themonths between August and June She says that an onslaught of tests that she′s required to give toher five-and six-year-old students has brought her down to reality.
"It′ s more than a first-year teacher ever imagines," Asselin said."You definitely have a lot ofhighs and lows, and it keeps going up and down and up and down."
New federal data that the Education Department released in April shows that about 10 percent ofnew teachers leave the profession within the first year on the job, and 17 percent leave within five yearsof starting. Though far lower than earlier estimates, it still means that many young educators bail fromthe classroom before they gain much of a foothold. For Asselin, testing has been the biggest stressor.
The proliferation of testing in schools has become one of the most contentious topics in U.S.education. The exams can alter the course of a student′s schooling and can determine whether ateacher is promoted or fired. In Virginia, schools earn grades on state-issued report cards based onthe scores students earn on mandatory end-of-year exams.
The Fairfax County school system, one of the nation′s largest, boasts that its kindergartenstudents take part in coursework that exceeds the state′ s standards. Unlike most states, Virginia hasnever adopted the Common Core State Standards, but Virginia officials say that the state′ s academicstandards are just as--or more--rigorous.
Asselin said that means that even the youngest students in public school are trader an academicmicroscope, making kindergarten about far more than socialization and play time.
Why does Asselin question her future as an educator in less than a year′ s time

A.It is a common practice for American young teachers.

B.She has experienced too many highs and lows in her work.

C.It is totally beyond her expectation to give kids endless test.

D.She has grown tired of greeting her kindergartners every day.
