I clearly remember my mom telling me to drink milk every day—one glass in the morning and another at night. I also remember loving it while my sister thought quite the opposite—she would surreptitiously pour her milk into the sink or water the plants with it! I guess I should thank my mom for making us drink a lot of milk, so rich in calcium(鈣), during those important years.

   Today, calcium shortage is one of the main concerns of women in their 30s or even early 20s. The great fear is that when we reach our 50s or 60s, osteoprosis(骨質(zhì)疏松癥)will set in. That is why you can see a lot of advertisements for products supposedly containing a lot of calcium.

   Because calcium is not that easy to acquire from the food we normally eat, busy women these days should take calcium supplements(補充物). There are a lot of different forms of these---calcium carbonate(碳酸鈣)，oyster(牡蠣)shell or bone-meal-based calcium supplements.

   You have to be careful when choosing which kind to take. This is because calcium is not easily absorbed by the body. So the fact that you are taking supplements doesn’t mean that the body is actually benefiting from them. Different supplements may have different instructions on dosage(劑量)and manner of intake. You can ask your doctor to help you determine which supplement is the best for your needs.

From what the author’s mother did we may infer that___________________.

A. her children had osteoporosis

B. she knew her children would benefit from milk

C. she must have suffered from osteorosis

D. she didn’t like her daughter who didn’t obey her order

Based on the passage, which of the following is NOT true?

   A. The author’s sister will suffer from osteoprosis when reaches her 50s or 60s

   B. Many businessmen have already been selling products supposedly containing calcium.

   C. We can’t get enough calcium only from food we eat every day

   D. Women as young as their 20s should be concerned about calcium shortage

What does the underlined word “surreptitiously” in the first paragraph probably mean?

   A. Honestly           B. Frankly           C. Secretly          D. Curiously                                

We may infer from the last paragraph that____________________.

   A. what one chooses as a calcium supplement might not work

   B. one shouldn’t take in calcium without the permission of a doctor

   C. the more calcium supplements one uses, the more calcium one can take in

   D. it is dangerous to use calcium supplements without the guidance

Four people in England back in 1953, stared at Photo 51,It wasn’t much—a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed –the shape of DNA The discovery brought fame and fortune to scientists James Watson, Francis Crick, and Maurice Wilkins. The fourth, the one who actually made the picture, was left out.

Her name was Rosalind Franklin.”She should have been up there,” says historian Mary Bowden.” If her photos hadn’t been there, the others couldn’t have come up with the structure.” One reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholars doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitors

At Cambridge University in the 1950s, Watson and Click tried to make models by cutting up shapes of DNA’s parts and then putting them together. In the meantime, at King’s College in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflection the shape.

But Wilkins and Franklin’s relationship was a lot rockier than the celebrated teamwork of Watson and Crick, Wilkins thought Franklin was hired to be his assistant .But the college actually employed her to take over the DNA project.

What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return, “Mere inspection suggested that she would not easily bend. Clearly she had to  go or be put in her place.”

As Franklin’s competitors, Wilkins, Watson  and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel Prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin, Watson wrote his book laughing at her. Crick wrote in 1974 that “Franklin was only two steps away  from the solution.”

No, Franklin was the solution. “She contributed more than any other player to solving the structure of  DNA . She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the “Dark Lady of DNA”, Franklin is finally coming into the light.

1.What is the text mainly about?

A. The disagreements among DNA researchers.

B. The unfair treatment of Franklin.

C. The process of discovering DNA.

D. The race between two teams of scientists.

2.Watson was angry with Franklin because she     .

A．took the lead in the competition            B．kept her results from him

C．proved some of his findings wrong          D．shared her data with other scientists

3.Why is Franklin described as “Dark Lady of DNA”?

A. She developed pictures in dark labs.

B. She discovered the  black X-the shape of DNA.

C. Her name was forgotten after her death.

D. Her contribution was unknown to the public.

4.What is the writer’s attitude toward Wilkins, Watson and Crick?

A．Disapproving.      B．Respectful.        C． Admiring.         D．Doubtful.
