题目内容

Science and technology have advanced at such a rate that cloning has now become a reality. The possibility of cloning humans is a serious subject and raises moral questions. In my opinion, cloning is useful for research into cures for disease. However, I think that it needs to be done with warning and carefully controlled by governments.

Research into cloning and stem cell (干细胞) production is chiefly aimed at finding new treatments for currently incurable illnesses. While this would improve the quality of life for many, not enough is understood about what effects cloning would have on the world in the future. This is primarily because we do not understand enough about the results of cloning and both the physical and psychological effects that it is likely to have on cloned individuals and on the rest of the world.

Furthermore, it is thought that a cloned individual would be unlikely to survive birth and would suffer from complications (病发症) resulting from changed organs (器官). There are also quite serious moral subjects as well as a risk. Those who are against cloning would argue that scientists have no right to play God and to destroy the natural processes. Producing embryos (胚胎) for the purpose of harvesting stem cells for research presents significant questions about the nature and status of the embryo being produced. It may also make us question whether getting rid of it after use reduces the value we place on human life.

1,3,5

In conclusion, I do not agree that research into cloning using human embryos should continue. This is not only because it may reduce the value we place on human life, but also because not enough is known about the results. However, I do think that if there is a way to produce stem cells using cloning which does not put human life at risk, then governments should continue to support it.

I chose to study in Madrid because I had a desire to learn Spanish. My first impressions of Madrid were incredible. It was before the New Year that I arrived in Madrid for the first time. While traveling to my Spanish friend’s house in a taxi, I appreciated the buildings along the road which were different from those of my own country.
There are an incredible number of restaurants and bars from all over the world. If you are really into sightseeing, I hope you have rechargeable batteries for your digital camera, because one week really isn’t enough time to see everything here including a number of art, science, and historical museums as well as parks, buildings, and amazing landscapes.
What I liked best about life in Madrid was the fact that if you were frustrated with schoolwork and wanted to have some fun, you can easily go out. The nightlife never seems to stop and the people are all very friendly. You can meet people and practice Spanish while having fun at the same time.
What I liked least was the fact that many people smoked in the streets. Also, coming from the US, I was used to having a big breakfast every morning, but while living with an actual Spanish family, I wasn’t really satisfied with the food in the morning.
I think I have definitely become more independent since I came back from Spain. Living in a big city like Madrid I found that it is necessary to plan ahead and to make a schedule (时间表) for future. There is so much to see, not just in the Spanish World, but in the European World as well.

At the middle school level, there are many academic clubs in which students can participate. Students can choose clubs that focus on an area of interest.
Mathcounts Club
Mathcounts tries to increase excitement towards mathematic achievement. It hopes to provide students with the foundation for success in science, technology, engineering and mathematics careers. Schools select individuals and teams to participate in competitions. Local competitions are held in February with winners progressing to state competitions and then on to the national level. Mathcounts works to challenge student math skills, develop self-confidence and give rewards for their achievements.
Envirothon
The Envirothon program focuses on natural resources knowledge and exposes students to diverse environmental issues, ecosystems, and topography. The ecology field competition for five-member middle school teams offers competitions in wildlife, soils, forestry, current environmental issues and aquatics. Students work and learn in middle school clubs and can compete at the local and state level.
Future Problem Solvers
Future Problem Solvers is an academic club that uses a six-step process to solve problems that may happen in the future. Students who are in the talented and gifted program, who like to “think out of the box,” or who enjoy thinking about futuristic problems may like this club. Teams comprised of four students read future scenes and write up solutions in a booklet using the six-step process. Teams that score high enough can go to the state competition and then to the international competition.
Builders Club
Builders Club is open to any middle school student who wishes to perform community service. Each Builders Club is co-sponsored by a Kiwanis club and the middle school. The members learn by doing, and they learn organization, teamwork, and leadership. Builders Clubs can sponsor a "Teacher of the Year" program, provide a recycling collection point, organize canned food and clothing drives to support local shelters, adopt a resident at a local senior citizens home, adopt a highway, tutor, etc.
Middle school academic clubs offer students a place to explore interests or talents. The clubs they join in middle school can help guide choices in high school and beyond.

2009 is the year of what? Yes, it is the year of the Ox. But do you know that 2009 is also the year of the telescope? This year the world celebrates the 400^th anniversary of Galileo Galilei’s observations of the universe through an astronomical telescope. In 1609, the Italian scientist first pointed a “Dutch perspective glass” at the night sky and made discoveries that changed mankind’s conceptions of universe.

In honor of Galileo’s discoveries, the United and the I International Astronomical Union have declared 2009 to be the Inter national year of Astronomy (IYA2009)

IYA2009 is a yearlong celebration of astronomy. Its goal is to spread knowledge of astronomy’s contributions to society and culture and to inspire more interest in astronomy and science, especially among young people. The theme of the celebration is “The Universe, to Discover.”

One interesting objective of the IYA is to encourage more diversity in the field of astronomy and physics. IYAS organizers hope that the yearlong celebration of astronomy will inspire more females and underrepresented minorities to purse careers in science. An event that will help further that goal is 100 Hours of Astronomy (100HA) that will fall on April. This event aims to have as many people as possible look through a telescope. From April 2^nd to 5^th, millions of people worldwide will peer through telescopes to catch their first glimpse of the universe, just as Galileo did 40 years ago. Sidewalk astronomy events will give city-people an excellent opportunity to see the moon, the planet Saturn, and other objects in position for early evening observations.

Organizers hope that the activities of IYAA will “promote a greater appreciation of the astronomy.” So join the fun. Look through a telescope this year!

60. What does the article mainly talk about?
