Different vitamins are found in different foods. Then which food should be eaten to keep us healthy? Let’s look at some important vitamins for the answer.

       Vitamin A helps to protect skin from becoming dry. It is also helpful to the eyes. Without vitamin A, you cannot see well in darkness. Vitamin A is found in animal liver and the yellow part of eggs. Sweet potatoes, carrots and other dark-coloured fruit and vegetables have something that body can change into vitamin A.
       Vitamin B changes food into energy and helps the heart and nerve system to work smoothly. Vitamin B also helps to produce red blood cells.Without it, we will be weak and will not grow. It is found in grains and other foods like beans, nuts, meat and fish.
       Vitamin C is needed for strong bone and teeth, and for healthy blood vessels. It also helps wounds to cure quickly. The body stores little vitamin C, so we must get it everyday in foods like oranges, tomatoes and cabbage.
       Vitamin D increases the level of calcium in the blood. Calcium is needed for nerve and muscle cells to work normally, as well to build strong bones. Fish liver oil has vitamin D. In some countries, milk producers add vitamin to milk so that it will be good for children.

【推荐1】Don’t Cry, Mom


One day, when I walked into the kitchen, I saw my mom crying. “Mommy, what happened? Why are you sad?” I asked.

Mom smiled at me. “I have tears in my eyes,” she said. “But I am not sad.”

“I am cutting onions, as you can see.” Mom said.

“Onions have a strong chemical that hurts our eyes. But don’t worry. Our body is amazing. It senses the danger of this chemical and sends tears to our eyes to get rid of it. Tears protect our eyes from danger.”

That is interesting! I learned something else too. All animals cry to protect their eyes. But humans are the only animals that cry when they are sad.

I love learning about my body. It all seems to work perfectly! The more I learn about it, the more amazed I am.

文章大意:本文主要介绍了早起的好处。

【推荐2】Some people like to get up early, but some do not. In fact, it is really good for us to get up early every day.

Maybe those who don’t like getting up early will not believe this, but it is really true. Scientists made a survey(调查)in about at least one thousand people, and then they found that early rising(早起)people had less disease than late rising people, and early rising people also look healthier than late rising people, and so on.

So we may know early rising is helpful in more than one way. First, it helps to keep us healthy. We all need fresh air. But air is never so fresh as early in the morning. Besides, it is useful to do morning exercises or play sports in the early morning.

Secondly, early rising helps us in our studies. In the morning we usually learn more quickly and find it easier to understand what we learn.

Thirdly, early rising can give us a plan of our work for the day. We cannot work well without a good plan.

Fourthly, early rising gives us enough time to get ready for our work, such as to wash our hands and faces and eat our breakfast.

Late risers may find it difficult to form the habit of early rising. They have to make an effort(努力)to do so. As the English proverb says, “Early to bed and early to rise makes a man healthy, wealthy and wise.”

1. Early rising people are usually ________ than late rising people.
A.fatterB.thinnerC.healthierD.cleverer
