"I think you are just telling me a story," the spider said with a smile. "Oh no, it is true," the little bug said. "All the stalks will be knocked down, and the corn will be gathered up. You will be killed by the giant machines if you stay here." "I don't believe you," the spider said as she ate the little bug for lunch.

It helps them grow strong because it is rich in protein , calcium and vitamins. Milk can also help you sleep better because it calms you down. But remember to drink milk with care. Find out how old the milk is. Make sure it is fresh and hasn't gone bad. Don't drink milk when your stomach is empty. Eat some bread or corn at the same time. That'll help you take in more protein and vitamins. Doctors say teens need at least 500ml of milk a day. That's two or three cups. Milk-drinking started long ago, as early as 6,000-8,000BC. At that time people started to keep cows, sheep and goats to get their milk. Of course what you drink today isn't that fresh from the cow. People cool the fresh milk down to 40C to stop the bacteria growing. In factories, milk is pasteurized to stop it growing bad. After disinfections and packaging, it goes to the supermarkets. Yoghourt also comes from milk. People make some special bacteria to change the taste of milk and make the nutrients in it easier for people to take in. Maybe that's why it's getting more popular with people! Question: When you drink milk , you'd better _ . Options: A: find out when the milk was produced B: make sure it's fresh and hasn't gone bad C: not drink milk when your stomach is empty D: do all of the above
