One day, you open the fridge and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She wants to cut off the moldy part and eat the rest. Is it safe to do this?

Mold (霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad and it’s not safe to eat. If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains water inside. And the water inside allows mold to easily grow below its surface. Bacteria (细菌) can also grow along with it.

But it’s easy to clean mold from hard food. The mold can’t grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold to clean it. It’s OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, throw it away.

Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillium (青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat and they’re quite delicious as well.

So, if the food is not the special cheese, stop your mother from eating it!

文章大意:本文讲述了校长如何通过与学生一起进餐来了解学生饮食喜好并改善学校食堂饮食。

【推荐2】Wu Yue, a 14-year-old student at a Junior High School in Hangzhou, usually has lunch with his classmates in their dining hall. But one day, a newcomer, the school headmaster, joined them at the same table. They talked about the food that the dining hall offered and had a nice chat.

Wu is not alone. Many students across China have the chance to eat with their headmasters. The government issued a notice on food safety and nutrition (营养) management in schools, asking headmasters from kindergarten to high school to have meals with students. The rule took effect (生效) on April 1st.

Many schools now have seats for school managers when they eat with students in the dining hall. After talking with them, the managers have to write reports and make suggestions to dining hall workers. Many students were asked about the food that they liked most. To their surprise, their favorite dishes appeared in the dining hall later. “It’s not just about the food. It makes me feel that I have a say in school,” explained one student. “My ideas are valued.”

Some headmasters regard these mealtime conversations as their main chance to communicate with students. And they notice that some students prefer meat to vegetables. “We are thinking about how to improve the dining hall’s dishes and provide students with a healthy diet,” one headmaster said. As students become more familiar with the school managers, they begin to express their own points of view.

“It’s important to understand students’ requirements. Our practice shows the school’s sense of responsibility,” another headmaster said.

1. Who is the newcomer to have lunch with students at the dining hall?
A.The new student.B.The school teacher.C.The school headmaster.
2. When did the rule take effect?
A.On April 1st.B.On March 1st.C.On January 1st.

A.They have to write reports and make suggestions to dining hall workers.
B.They have to play games with students on the playground.
C.They have to help the dining hall workers do some cleaning.
4. According to paragraph 4, what are the school managers thinking about?
A.How to improve their dining hall conditions.
B.How to provide students with a healthy diet.
C.How to communicate with the parents.
