There are many ways to cook an egg.
What's the best way to boil an egg? Scientists in Italy think the answer is “periodic（周期的）cooking”.
In cooking， we often talk about two parts of the egg. One is the yolk（蛋黄）and the other is the egg white. They have different nutrients（营养）and need different temperatures for cooking. So， it is difficult to cook both parts just right once and for all.
Scientists first ran tests on a computer. They found that changing the water from hot to warm again and again was a good way. It may help the yolk and egg white reach their perfect temperatures at different times.
Then， the scientists tried the new way on real eggs. They put the eggs in boiling water（100℃）， and moved them to 30℃ water every two minutes. They kept doing this for 32 minutes， and then cooled the eggs under running water. The eggs tasted wonderful. The egg white was very soft and the yolk was creamy.
OTHER ways of boiling eggs
● Hard-boiling： Eggs stay in boiling water for 10 to 12 minutes. It makes the egg rubbery（有弹力的）.
● Soft-boiling： Eggs sit in boiling water for 4 to 6 minutes. The yolk is still a little runny（流动的）by the end.
● Sous vide（低温慢煮）： Eggs stay in warm water between 60℃ and 70℃ for at least an hour. It makes both the yolk and egg white creamy.
1. What are the two parts of an egg mentioned in the article?
The two parts are the yolk and the egg white.
2. How long did the scientists cook the eggs in their new way（periodic cooking）?
They cooked the eggs for 32 minutes.
3. Why is it difficult to cook both the yolk and egg white perfectly at the same time?
Because the yolk and egg white have different nutrients and need different temperatures for cooking.
4. Compare the soft-boiling way and the periodic cooking way. How are they different in looking result?
In soft-boiling， the yolk is a little runny. In periodic cooking， both the egg white and yolk become soft and creamy.
5. Do you think what is the best way to boil an egg in the passage? Give a reason.
(合理即可)I think periodic cooking is the best way because it gives a perfect result.
