Eggs-perimenting with eggs
What can you do with eggs other than eat them?
Naked Eggs
What does an egg look like without its shell? You may be picturing the white and yolk in a bowl after cracking it, but that isn’t the only way to remove the shell.
Materials: an egg, white vinegar, a bowl, a spoon
Directions: Fill a bowl with one cup of vinegar. Add the egg to the bowl, and wait at least 24 hours. When you check it after a day, you’ll notice some bubbles on the egg and a residue (残留物) in the water. Use the spoon to gently remove the egg from the bowl. Dump out the old vinegar, and add a cup of fresh vinegar. Return the egg to the bowl, and wait another 24 hours. When you remove the egg this time, the shell should be completely dissolved. What remains will be the contents of the egg.
Walking on Eggshells
Can Eggs hold the weight of your entire body?
Materials: six cartons (硬纸盒) of eggs, a garbage bag
Directions: Place the garbage bag on the floor to make any necessary clean up easier. Place the cartons of eggs into two rows of three. Make sure all the eggs are pointing in the same direction— either all pointy end up or all rounded end up. Step onto the first carton of eggs carefully. Make sure your foot is as flat as possible and that you are distributing your weight evenly. If you’re careful, you will succeed. Eggs are actually incredibly strong. The arch shape at the top and the bottom of the egg allows pressure to be distributed evenly over the egg. If you were to place the eggs on their sides instead, you’d be likely to wind up with a gooey (胶粘的) mess.

【推荐1】Measles (麻疹), which once killed 450 children each year and disabled even more, was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine (疫苗). But the disease is making a comeback, caused by a growing anti-vaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, compared with 189 for all of last year.
The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates are very high, as they still are in the nation as a whole, everyone is protected. This is called “herd immunity”, which protects the people who get hurt easily, including those who can't be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn't work.
But herd immunity works only when nearly the whole herd joins in. When some refuse vaccination and seek a free ride, immunity breaks down and everyone is in even bigger danger.
That's exactly what is happening in small neighborhoods around the country from Orange County, California, where 22 measles cases were reported this month, to Brooklyn, N.Y., where a 17-year-old caused an outbreak last year.
The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who refuse to take that risk selfishly make others suffer.
Making things worse are state laws that make it too easy to opt out (决定不参加) of what are supposed to be required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption(豁免), sometimes just by signing a paper saying they personally object to a vaccine.
Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does enough to limit exemptions.
Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinions? Not good enough. Everyone enjoys the life-saving benefits vaccines provide, but they'll exist only as long as everyone shares in the risks.
What is the purpose of the passage?
A.To introduce the idea of exemption. |
B.To discuss methods to cure measles. |
C.To stress the importance of vaccination. |
D.To appeal for equal rights in medical treatment. |
