閱讀下面短文，根據(jù)短文內(nèi)容回答問題。

Recently, more and more people pay attention to eating healthily. Some food additives(添加劑) are used to make different kinds of foods. Some of them can make the food more delicious and some of them can make it colorful. But lots of chemicals are used to produce what we eat every day.

Sudan red is a kind of chemical that factories used it to dye cloth, make the shoes brighter. But some people produced salted duck eggs with it . However, it isn’t a kind of food additive. The food made from Sudan red makes it easier to cause cancer. Melamine(三聚氰胺) is another kind of chemical that are banned(禁止). It’s white crystal(晶體), which was discovered by a German chemist called Sustus Von Liebig in 1834. Melamine can be used to make paper, medicine and woods, ect. But nobody can imagine that some people used it as a material of milk powder(粉末). Because of melamine, it’s reported that 4 babies died and more than 50 thousand babies are affected since 2008. Sanlu, a famous milk powder factory was closed. What’s worse, milk powder with melamine appeared in 2011 again. Problems of food safety, for example, poisonous rice, lean meat powder(瘦肉精) and plasticizers(塑化劑) are becoming more and more serious.

Fortunately, lots of laws have been made to make the solution(解決方法) better. We think we will eat more healthily in the future.

1.Can the food additives make the food colorful and more delicious?

2.What is Sudan red?

3. When was melamine discovered?

4.請將劃線句子翻譯成漢語。

5.為了保證食品安全，避免類似事件發(fā)生，請你用英語給負(fù)責(zé)食品安全的相關(guān)部門提出建議（只需一條即可）。
