From babies to body builders, we all have muscles. They grow, they bulge(鼓起), they stretch they stretch and sometimes they even painfully pull. But for all the work they do for us, we are still unable to crown one as "the strongest muscle."
Instead, a few muscles could claim the title, depending on how strength is measured.
If the title goes to the muscle that can exert(产生) the most force, the victor would be the soleus(小腿肚肌), according to Gray's Anatomy(解剖学). Without this muscle, we wouldn't be able to stand, walk, run or shake our bodies on the dance floor. If the soleus was not continuously pulling, we would always be falling over ourselves (although some of us tend to do that from time to time anyway).
But perhaps the title should go to the muscle that exerts the most pressure. Pressure is different from force — pressure takes into account the area over which a force is exerted. The muscle that takes the prize for delivering the greatest amount of pressure is the masseter, or the jaw muscle, according to the book "Clinical Oral Science" (Reed Educational and Professional Publishing, 1998).
In 1986, Richard Hofmann of Lake City, Fla., achieved a bite strength of 975 pounds (442 kilograms) for two seconds, setting a Guinness Record. Talk about jaw dropping! The jaw is able to clench(咬紧) and chew because of the masseter muscle.
Others may argue the muscles used in childbirth are the most powerful.
When it comes to versatility, perhaps the tongue is the strongest muscle. Its combination of elasticity(伸缩性) and forcefulness gives us the ability to speak, eat and kiss – all things very desirable on a first date. However dexterous(灵巧的) it may be though, its power does not match that of muscles such as the soleus.
If slow and steady wins the race, the heart is certainly a contender for the title. When it contracts, the muscle pumps about 2 ounces (59 milliliters) of blood, and is constantly working over a lifetime. Beating about 40 million times a year, a person's heart will beat approximately 2.5 billion times by the time of their 70th birthday.
According the passage, the underlined word “contender” in the last paragraph is closet in meaning to “ ”.
A.failure B.partner C.muscle D.competitor

D
My father’s family name being Pirrip, and my Christian name Philip, my infant tongue could
make of both names nothing longer or more explicit than Pip. So, I called myself Pip, and came to
be called Pip.
As I never saw my father or my mother, and never saw any likeness of either of them (for their days were long before the days of photographs), my first imagination regarding what they were like, were unreasonably from their tombstones. The shape of the letters on my father’s gave me a strange idea that he was a square, dark man , with curly black hair. From the character and turn of the words, “Also Georgiana Wife of the Above,” I drew a childish conclusion that my mother was freckled(长雀斑的)and sickly.
Ours was wet country, down by the river, within, as the river wound, twenty miles of the sea. My first most vivid and broad impression of the identity of things, seems to me to have been gained on an unforgettable cold afternoon towards evening. At such a time I found out for certain, that this place overgrown with nettles(荨麻)was the churchyard(墓地);and that Philip Pirip, and also Georgiana wife of the above, were dead and buried; and that Alexander, Bartholomew, Abraham, Tobias, and Roger, infant children to the aforesaid, were also dead and buried. Suddenly I began to feel lonely and sad and afraid. I began to cry.
"Hold your noise!" cried a terrible voice, as a man started up from among the graves at the side of the church porch. "Keep still, you little devil, or I'll cut your throat!"
A fearful man, all in grey, with a great iron on his leg. A man with no hat, and with broken shoes, and with an old rag tied round his head. A man who had been shivered; and whose teeth chattered in his head as he seized me by the chin.
"Oh! Don't cut my throat, sir," I pleaded in terror. "Pray don't do it, sir."
"Tell us your name!" said the man. "Quick!"
"Pip, sir."
"Once more," said the man, staring at me. "Give it mouth!"
"Pip. Pip, sir."
“Show us where you live ,” said the man. “Point out the place!”
I pointed to where our village lay, among the alder-tree, a mile or more from the church. The man, after looking at me for a moment, turned mw upside down, and emptied my pockets. There was nothing in them but a piece of bread. When the church came to itself—for he was so sudden and strong that he made to go head over heels before me, and I saw the steeple(尖塔)under my feet—when the church came to itself, I say, I was seated on a high tombstone, trembling, while he ate the bread hungrily.
“You young dog,” said the man, licking his lips, “what fat cheeks you have got.”
I believe they were fat, though I was at that time undersized for my years, and not strong.
“Darn me If I couldn’t eat them,” said the man, with a threatening shake of his head.
I carefully expressed my hope that he wouldn’t, and held tighter to the tombstone on which he had put me; partly, to keep myself upon it; partly, to keep myself from crying.
“Now look here!” said the man. “Where’s your father?”
“There sir!” said I .
He started, made a short run, and stopped and liked over his shoulder.
“There sir!” I explained. “That’s his grave.”
“Oh!” said he, coming back.
“And mother’s there too, sir. And my five little brothers.”
67.Who do you think Alexander is?
A.Pip’s friend. B.Pip’s father.
C.One of Pip’s little brothers. D.The fearful man.
68.It can be learned from the passage that .
A.Pip’s mother was freckled and ill.
B.Pip imagined what his parents liked through their photographs.
C.Pip’s parents and little brothers were killed by the man.
D.Pip was probably shorter or thinner than most children of his age.
69.What is the fearful man most likely to be?
A.An escaped prisoner. B.A minister of the church.
C.A tower watcher. D.Pip’s parents’ enemy.
70.Which of the following is right according to the passage?
A.It was the words on the tombstones that made mw know of my parents’ appearance.
B.The man was so hungry that he wanted to cut his throat and eat his fat cheeks.
C.Pip’s parents were buried together in the churchyard 20 miles from the village.
D.He called himself Pip just because he was too young to pronounce his long name clearly.

查看习题详情和答案>>When I was growing up in America, I was ashamed of my mother’s Chinese English. Because of her English, she was often treated unfairly. People in department stores, at banks and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.
My mother has realized the limitations of her English as well. When I was fifteen, she used to have me call people on phone to pretend I was she. I was forced to ask for information or even to yell at people who had been rude to her. One time I had to call her stockbroker(股票经纪人). I said in an adolescent voice that was not very convincing, “This is Mrs. Tan.”
And my mother was standing beside me, whispering loudly, “Why he don’t send me cheek already two week long.”
And then, in prefect English I said, “I’m getting rather concerned. You agreed to send the check two weeks ago, but it hasn’t arrived.”
Then she talked more loudly. “What he want? I come to New York tell him front of his boss.” And so I turned to the stockbroker again, “I can’t tolerate any more excuse. If I don’t receive the check immediately, I am going to have to speak to your manager when I am in New York next week.”
The next week we ended up in New York. While I was sitting there red-faced, my mother, the real Mrs. Tan, was shouting to his boss in her broken English.
When I was a teenager, my mother’s broken English embarrassed me. But now, I see it differently. To me, my mother’s English is perfectly clear, perfectly natural. It is my mother tongue. Her language, as I hear it, is vivid, direct, and full of observation and wisdom. It was the language that helped shape the way I saw things, expressed ideas, and made sense of the world.
