Abraham Lincoln was born in Kentucky in 1809. His mother died when he was ten years old. Later, his family moved to Illinois and his father remarried. The family was poor, so they had to struggle just to live. In Illinois, there were neither teachers nor schools, but Lincoln’s stepmother encouraged him to study. He learned to read and write while working on the farm.
At twenty-one, Lincoln left home. He soon received a law license and became a lawyer. People trusted him and began to call him “Honest Abe”.
During the following years, he took a more active part in polities. Soon he was not only a highly respected lawyer but also a well-known politician. He was elected the sixteenth president of the United States in 1860, and in the next year the Civil War broke out.
The Civil War was between the southern states that wanted to leave the Union and form their own country, and northern states that wanted to keep all the states as one country. The southern states wanted to keep the laws that allowed them to own slaves. Both the northern states and President Lincoln wanted to get rid of those laws. On April 9, 1865, the Civil War ended and all slaves were set free.
Less than a week later, on April 14, 1865, Abraham Lincoln was shot at the Ford Theater in Washington D.C. He died the next day from his wounds.

Keep More Food on the Table
It’s said that in some parts of the world, people are facing the problem of hunger. So what can we do to help them? Here are some suggestions:
Cook from the fridge
Start with the fresh foods. If you have some in the fridge, use them first. Make a meal with what you have got instead of running out to the supermarket for something else.
Learn to read the labels
“Best-before” and“use-by” dates are more important. Learn to know the different periods of foods and know how to cook them in the right way. For example, black bananas are proper for baking, fresh vegetables are good in soups, and bread that is not fresh can be turned into small pieces.
Use the freezer(冷冻室)
The freezer can keep foods fresh until you are ready to cook them, and store the cooked foods until you’re ready to eat them. It’s also the best place for the remaining food. Mark the date of the food nearby, so it’s easy to find the foods you need to eat first and you will never leave them there for too long.
Shop with a list
Plan meals ahead of time so that you know exactly what to buy. Doing this helps reduce food waste because it’s possible to buy too much of a certain food and then forget to eat or cook it later.
