There’s a lot we know about eggs: they are great for breakfast and you can cook them in different ways. One topic of debate, however, is why brown chicken eggs usually cost more than white ones. According to Sharman Hickman, the director of Community Outreach and Education for Hickman’s Family Farms, genetics (基因学) not nutrition determines the eggshell color and thus the egg’s price.

The chicken breed (品种) and their genetics decide whether or not hens have pigment (色素 ) genes, which coat the egg and result in a colored shell during the egg-laying process. Although all eggs start out white in color, shell color can range from white to brown and even blue in some rare breeds, Hickman adds. Breeds such as the Leghorn chicken lay white eggs, while the Orpington lays brown eggs and the Ameraucana produces blue eggs.

Hickman notes that the Leghorn breed is the most efficient egg-laying hen, making it a popular choice for farmers. Hens that produce colored eggshells, however, tend to be larger and require more feed and energy to create that painted layer. Since those breeds cost more to feed, their eggs are more expensive.

Although eggs sometimes look different and are priced differently, it’s impossible to know

their nutritional make-up from the shell color alone, according to Malina Linkas Malkani, media spokesperson for the Academy of Nutrition and Dietetics. “Choosing between brown and white eggs is a matter of personal preference,” she says. “But it’s important for people to know that the color of the eggshell has nothing to do with the egg’s nutrient content or shell thickness.”

What does affect the nutrient content is the specific diet the hen is on, according to Malkani. For example, hens fed with a diet with omega-3s and vitamin D produce eggs that are higher in those specific nutrients. No matter what your preference is, don’t judge an egg by its shell color.

1.Which of the following is one of the arguments about eggs?

A.Which eggs are difficult to break.

B.How eggs can be cooked healthily.

C.Why colored eggs are more expensive.

D.What the best time to eat eggs should be.

2.What makes the eggshell color different?

A.The hen’s breed. B.The size of the hen.

C.The color of the eggs inside. D.The length of the laying process.

3.Why do farmers love the Leghorn breed more?

A.They lay brown eggs. B.Their eggs are larger.

C.Their eggs sell better. D.They are productive.

4.What can we learn from Malkani’s words in the last paragraph?

A.It takes efforts to test eggs’ nutrition.

B.It’s meaningless to study an eggs color.

C.Personal preference matters a lot in choice-making.

D.An egg’s nutrition is closely related to the hen’s feed.

Doctor are known to be terrible pilots. They don't listen because they already know it all. I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn't realize then, but becoming a pilot makes me a better surgeon. I loved flying. As I flew bigger, faster planes, and in worse weather. I learned about crew resource management (机组资源管理), or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.

I first read about CRM in 1980. Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot He was so busy because of the bad turn, he had forgotten to put the landing gear (起落架) down. He was a better pilot - and my boss - so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness and said, "We need to put the landing gear down now!" That was my first real lesson in the power of CRM, and I've used it in the operating room ever since.

CRM requires that the pilot/ surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn't overreact, which might prevent fellow doctors from voicing opinions again. So when I'm in the operating room, I ask for ideas and help from others. Sometimes they're not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from ”landing gear up”.

1.What does the author say about doctors in general?

A. They like flying by themselves.

B. They are unwilling to take advice.

C. They pretend to be good pilots.

D. They are quick learners of CRM.

2.The author deepened his understanding of the power of CRM when_______.

A. he saved the plane by speaking up

B. he was in charge of a flying task

C. his boss landed the plane too late

D. his boss operated on a patient

3. In the last paragraph”landing gear up” probably means ______.

A. following flying requirements.

B. overreacting to different opinions.

C. listening to what fellow doctors say

D. making a mistake that may cost lives

4.Which of the following can be the best title for the text?

A.CRM: A New Way to Make Flying Safe

B. Flying Makes Me a Better Doctor

C. The Making of a Good Pilot

D.A Pilot-Tumed Doctor
