【題目】

Do you have a vegetable garden? Have you ever w【1】 a seed sprout and grow and fruit until it became the tomato on your plate? If you go to school in the US, there's a good chance you have.

At the moment, nearly 20 percent of schools in the US have vegetable gardens that are planted and cared for by students. Later, even more schools will have gardens and more US kids will know the p【2】of growing food in their school vegetable gardens.

Much of the growing interest in planting comes from First Lady Michelle Obama's “Let's Move” project. The First Lady wants to i【3】children's nutrition（營養(yǎng)）in the US-and she began her project by planting a garden at the White House with the help of some local kids. The kids were more i【4】in eating vegetables from their garden than in eating fast food. This gave the First Lady an idea.

Because so many US kids eat breakfast and lunch at school，the food should be healthy and good. Why not let kids grow the food for their o【5】cafeterias（食堂）？Mrs. Obama's plan gives money to schools to start their gardens，and more school gardens are sprouting up every day.

Students also use the i【6】from their gardens to study science and math，and they paint pictures of their gardens in art class. Many students choose to work in the garden instead of playing on the playground during their noon b【7】. Sound like fun？Ask your teacher if there's room for a garden at your school，too.

【題目】

Sometimes we forget that many things we use every day were not always there. They had to be i【1】. Someone had to have an idea. Then they had to do a lot of experiments with the idea until it worked well. Here are few you might like to read about:

In Maine, the northeast of the U. S., winters are long, windy and cold. Every winter, Chester Greenwood's ears got so cold that they turned colors. When he was 15, Chester got ice skates for his birthday. He wanted to go skating. The cold wind and his frozen ears soon sent him running home. The next day, Chester tied a scarf around his ears. It was w【2】, but too uncomfortable. Then he got a GREAT IDEA.

Chester made two oval loops out of wire. He asked his grandmother to sew covers on the ovals Then she connected the ovals with another wire. The ovals fit over his ears. Chester had invented earmuffs! They saved his ears and made him rich. People in Maine found another way to r【3】 Chester. December 21th, the first of winter, is Chester Greenwood Day.

Sometimes inventions happen by chance. As a boy. Thomas Alva Edison was called Al. When he was 12 years old, he got his first j【4】. He sold newspapers and candies on the train. One day on the job, he bravely s【5】 a boy from being run over by a train. The boy's father worked a telegraph. Al asked how to run a telegraph. Not only did Al learn the telegraph, but he made a better one. It was one of his earliest GREAT IDEAS

Edison's new telegraph made a lot of money. Later，he became the first person to o【6】and run an invention business. He was good at that，too. We could thank Thomas Edison every day. He had many，many GREAT IDEAS such as bulbs，movie cameras，and batteries. Edison is the one who invented more things than a【7】else in the world.

So，who knows？You might invent something some day！
