Read the article and select the best answer. Article: DNA is the whole "map" of the human body. It is something that all human have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own. People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called "genes" in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They're written in the DNA with a special language. In 1961, another two scientists found the first "word" that they could understand in that language. It shows how DNA tells the cell to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one "word" means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do. Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more "words" and and find out more information, we will use it in the wrong way, just to make people more attractive, or stop sick people getting jobs. Question: When did Mr. Mendel discover why we look the same as other people in our family? Options: A: In 2000 B: In 1961. C: In 1953 D: In 1860

Read the article and select the best answer. Article: Sometimes I really doubt whether there is love between my parents. Every day they are busy trying to earn money in order to pay the high tuition for my brother and me. They don't act in the romantic way that I read in books or I see on TV. In their opinion. "I love you" is too luxurious for them to say. Sending flowers to each other on Valentine's Day is even more _ . Finally my father has a bad temper when he's very tired from the hard work, it is easy for him to lose his temper. One day, my mother was sewing a quilt. I silently sat down beside her and looked at her. "Mom. I have a question to ask you." I said after a while. "What?" She replied, still doing her work. "Is there love between you and Dad?" I asked her in a very low voice. My mother stopped her work and raised her head with surprise in her eyes, She didn't answer immediately. Then she bowed her head and continued to sew the quilt. I was very worried because I thought I had hurt her. I was in a great embarrassment and I didn't know what to do. But at last I heard my mother say the following words: "Susan," she said thoughtfully. "Look at this thread. Sometimes it appears, but most of it disappears in the quilt. The thread really makes the quilt strong and durable . If life is a quilt then love should be a thread. It can hardly be seen anywhere or any time, but it's really there. Love is inside."
