Like all insects, ants have six legs. Each leg has three joints(關(guān)節(jié)). The legs of an ant are very strong so they can run very quickly. If a man could run as fast for his size as an ant can, he could run as fast as a horse. Ants can lift 20 times their own body weight.

The life of an ant is usually 45～60 days. Ants use their antennae(觸角) not only(不但)for touch, but also(而且) for smell. The head of an ant has a pair of large , strong jaws(顎). The jaws open and shut sideways like a pair of scissors(剪刀). Grown-up ants cannot eat hard(硬) food. Instead they have the juice that they get from pieces of food. They throw away the dry part that is left over. An ant has two stomachs. One stomach holds the food for itself and the other is for food to be given to other ants. Like all insects, the outside of their body is hard..

Each ant group has at least one or more queens(蟻后). The job of a queen is to lay eggs and worker ants look after them.

Worker ants look after the young, protect(保護(hù)) the nest(巢) from unwanted visitors and look for food. At night worker ants move the eggs and baby ants deep into the nest to protect them from the cold. During the daytime, worker ants move the eggs and babies to the top of the nest so that they can be warmer. Each group of ants has its own smell. In this way, visitors can be made out at once. If a worker ant has found where the food is, it leaves a special smell so that the other ants in the group can find the food. Ants are clean and tidy insects. Some worker ants are given the job of taking the waste from the nest and putting it outside in a special rubbish dump(堆)!

I will never forget the very moment that caused me to leave my gift behind because I wanted the gift that my older sister Maria had.

My family was spending a week at the beach. One morning, Maria went to the beach early, but I stayed behind to finish a drawing of a seashell. After finishing the drawing, I walked to join Maria. She was a top gymnast (體操運(yùn)動(dòng)員). Her show was perfect as she wheeled along the beach. The beauty of that sight froze me, and I decided immediately that I too would become a gymnast like her.

I knew that I had never been very good at sports. However, when I told my parents I wanted to take a gymnastics class, they agreed with me in surprise. The next week, I went to a beginners’ class.

   If only my parents had talked me out of this misguided plan! Five minutes into the first class, it was clear that I didn’t have the gift of a gymnast. But I kept at it.

   During this time, drawing and painting—which had been my two favorites—all but left my mind. It must have been hurting for my family as they watched my hopeless efforts. I blindly decided to be like Maria. I just would not give up.

   At the same time, on the advice of Ms. White, my art teacher, I hurriedly handed in my seashell drawing for an art contest in our town. One night as I was having a hard time practicing, the phone rang. It was Ms. White. “Alice, you won the contest!” she said loudly.

 “Really?” was all I could reply.

“Yes,” Ms. White said. “They’re going to give you a prize. And that’s not all. The winner is also accepted into Wildale’s Summer Fine Arts Institute.” I couldn’t believe what I heard. Only a handful of young artists were accepted each summer.

That night I didn’t go back into the living room to continue practicing. Gymnastics was Maria’s gift, not mine. It had taken me a while, but I realized that I had a gift of my own.

1.Alice wanted to be a gymnast because ________.

A. she had been good at sports                  B. her sister’s show was perfect

C. she hated drawing and painting               D. her parents wanted her to do so

2. How did Alice feel about learning gymnastics at last?

A. Satisfied.           B. Worried.             C. Hopeful          D. Regretful.  

3. From the story, we can infer that ________.

A. Alice’s parents disagreed with her choice of gymnastics

B. Alice did not realize her gift in drawing and painting at first

C. Alice spent a hard time preparing for the art contest in the town

D. Alice couldn’t believe the news that she got the prize for painting

4. What does the writer want to tell us according to the passage?

A. We should value our own gifts.           B. It takes time to find one’s gifts.

C. We could develop different gifts.        D. It’s never too late to show our gifts.
