On June 26th, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own. Now we can read some of this “map”, and so we can find out more about how our bodies work.
People have been trying to understand the human body for a long time. In 1860, Gregory Mendel discovered that there is a special reason why we look the same as other people in our family. It is because of small things called “genes” that we have in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are really messages written in the DNA with a special language.
In 1961, Marshall Nirenberg and Johann Matthaei found the first “word” that they could understand in that language, showing how DNA tells the cell to build its parts. This meant that one day we would be able to read all the messages that a human body gets from its parents’ bodies. Scientists have now found all the words in DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help save people from several diseases. 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 people who are very ill. Other people worry about that when we learn more words and find out lots of other information, we still use it in the wrong way, just to make people more attractive, or stop sick people getting jobs.
1.Could Francis and Craig read the “map” of DNA in 2000?
2.Why do we look like our parents?
3.When was the first “word” of DNA discovered?
4.What can the doctors do if we understand some messages in DNA?
5.What does the writer tell us in the last paragraph?

Planes have changed the world in the last hundred years. But this great change began with two ordinary people.
Orville and Wilbur Wright were two brothers. 1. .They were good at making bicycles, but planes were their real interest.
At that time, people knew how to build and fly gliders. But nobody could build a plane with an engine and fly it. The plane builders had two main problems: 2. . And the planes always crashed when they tried to take off.
The Wright brothers read about these problems in newspaper, and they decided to look for answers. They made small model planes in the bicycle shop and they built a wind tunnel(风道) to test the models. They also built real gliders. 3. .
On December17th, 1903, Orville and Wilbur pulled The Flyer onto a flat sandy beach. The plane weighted 275 kilograms. It had a petrol engine and two wooden propellers(螺旋桨). Two bicycle chains connected the propellers to the engine. 4. .The brothers threw a coin into the air to see who should fly first. Orville won. He climbed onto the plane and started the engine.
5. .Wilbur ran along beside the plane. And then the plane took off! It flew for only 12 seconds, but someone took a photograph, and the plane flew into the history books.
A. There was a wind about 30 kilometers per hour on that cold day B. Finally, they built a plane with an engine called The Flyer C. They could not make the wings strong enough D. They had a bicycle shop in Ohio, USA E. The Flyer began to move into the wind |
According to a new scientific research, we are rapidly going close to major climate change and the effects on the environment could be quite serious. Geographers predict that climate zones could completely disappear within the next eighty years. Where will crops be grown if this happens? When the climate changes a lot, polar regions will get colder and tropical regions will get even hotter. As a result, where will animals be forced to move on the earth?
Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes(飓风) will not only increase but may also become stronger. If the changes come too quickly, animals and plants may not be able to adapt(适应) right away and could disappear from the earth.
According to Science Daily, a new study predicts that, by the year 2100, many of today’s familiar climates will be taken place by climate unknown in today’s world. It is urgent that we reduce the risks of far-reaching results for the whole world. The planet itself has been showing signs of change. In 2004, a huge tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands more died in China in another big earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was destroyed seriously and became ruins in 2010 by another big earthquake.
Not long ago, scientists discovered ice melting(融化) in west Antarctica(南极洲). This is very worrying because temperatures in this area have remained rather constant(不断的) and actually even lower at time. Melting occurs when temperatures increase and since temperatures have remained, the ice should not be melting. However, satellite data(数据) shows melting around west Antarctica.
Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously expected. At this point, it doesn’t matter what is causing it, but rather, what can be done about it. On the other hand, our world is getting more and more unstable(不稳定) every year. Natural disasters(灾难) are becoming more frequent(频繁的) and serious.
However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connections between these. No one knows anything for sure at this point because there is simply not enough data.
1.What’s the writer’s attitude toward the climate changes?
A. We should observe the great changes of the climate carefully.
B. We must connect with other planets to prevent the climate changes.
C. We should try our best to do something against the climate changes.
D. We need to discover what causes the climate changes first of all.
2.What does the underlined word “tropical” mean?
A. cold and dry B. cool and wet
C. hot and wet D. warm and dry
3.What can be inferred from the passage?
A. Collecting more data will help us to solve the problem.
B. The climate will be much better than we have expected.
C. Earthquakes can be avoided in a few years’ time.
D. The ice in west Antarctica will stop melting in the future.
4.What’s the passage mainly about?
A. It tells us how to protect the environment of the earth.
B. It talks about the bad effects of the climate changes.
C. It shows us how to prevent diseases from spreading.
D. It describes what we should do with the earthquakes.
Sarasota, Florida teen band The Garbage-Men is performing on the stage. The band has five members. They are Jack Berry, Ollie Gray, Harrison Paparatto, Austin Siegel and Evan Tucker. The five teens are making music from waste. The Garbage-Men band’s instruments are made from recycled things. The guitars are boxes. A horn(号) is made from pipes. The keyboard is formed from old bottles.
The band started about two years ago. Jack Berry who was in eighth grade at the time decided to make a playable, home-made guitar, after some trial-and-error(反复试验), he ended up building it from a cereal box, a yardstick and toothpicks. After Jack showed his creation to his friend Ollie Gray, Ollie had the idea to form a band using other home-made instruments as a way to improve recycling. “We want to show people there is more to recycling than throwing things away in the bin.” Jack, 16, told TFK. “You can actually reuse materials.”
The Garbage-Men plays at local events around Sarasota, including festivals, farmer’s markets and community fundraisers. Typically, the teens will set up on the street and perform popular songs from the 1960s, including classic Beatles tunes and crowd favorite “Wipe Out,” by The Surfaris. In between sets, they talk about recycling and offer tips for how to help the environment. While they perform, Jack’s little brother Trent, 11, gives out flyers(宣传单) about recycling and helps sell the band’s CDs and other musical products.
The band donates(捐赠) the money from sales to charity. They have raised more than $2,500 for Heifer International. The organization gives farm animals, seeds and agricultural(农业的) training to people in poor countries to help end poverty and hunger. “It’s a good, sustainable-development (持续发展的)charity,” Jack says, “By donating one animal, you help the whole community.”
The band, all tenth graders, tries to play a show every week. They’ve also played on a Tampa, Florida radio station and auditioned(试演) for America’s Got Talent. The teens hope to eventually take their shows on the road by touring in other states. “Music is a really good way to get a good message across to people because it’s really accessible(可接近的),” Jack says. Their instruments may be rubbish, but their message isn’t.

Do you want to spend a holiday in space? Dennis Tito, a businessman, has become the world’s first “space tourist”. He went on a 10-day visit to the International Space Station. He paid 14 million pounds for his journey. A year later, Martin, a musician from an American band, wanted to do the same. He was only 22 years old and probably very rich too. He had to go for a lot of training to see whether he was fit enough to travel. He is still waiting for his holiday of a lifetime.
Many people believe that this is only the start of something new. We made interviews among teenagers from around the world and the following is what they said about space travel.
“It’s a great idea. I hope space travel will be common in about 50 years’ time. I’d really love to do it and I think Mr. Tito was very lucky.” (Kate from Australia)
“I would like to see our beautiful Earth from space. There are lots of secrets to explore in space and I would go into space if I could.” (Ben from China)
“I think space travel is really bad for the environment. Maybe in the future they will make a cleaner way of travelling but until they do, I don’t want to go. We should look after our own planet first.”(Richard from Canada)
“It must be very boring and dangerous to sit in that small space shuttle(舱). I’d rather take a plane and go to another place on earth.” (Lisa from the UK)
So, as you can see, many of our teenagers had different opinions. Whether you like it or not, space travel is going to become an important thing in the future. We are looking forward to hearing your opinions.
