For some people, it’s easy to get dressed for work. Pilots and police officers, for example, don’t have to make decisions about their work clothes. They wear uniforms to work every day.

     For many office workers, however, it is more difficult to choose clothes for work. They do not wear uniforms to the office. Also, many organizations are changing their dress codes. They are allowing their employees to wear casual(隨意的) clothes to work.

     The change to casual work clothes began in the 1990s. At first, many companies in the United States allowed employees to wear casual clothes on one day of the week—Friday. Friday became “Casual Friday” or “Dress-down Friday”. Today, however, many companies are allowing their employees to wear casual clothes every day of the week.

Some studies show that people are producing and achieving more when they are wearing comfortable clothes. Some companies also like the casual dress code because they don’t need to buy special clothes for work. They can save money this way.

      Unfortunately, a casual dress code can also cause problems. Sometimes employees think they can wear anything. Many companies have rules about casual clothes. They list the kinds of clothes that are not “business-casual” clothes. Blue jeans, sandals, and sportswear are examples of clothes that are usually too casual for the office.

At 9 a.m. on October 15, 2003, our country launched (發(fā)射) its first manned (有人的) space-ship, Shenzhou V, into space at Jiuquan Satellite Launch Center in Gansu Province. It took Yang Liwei and his spaceship about 21 hours to circle the earth 14 times. Yang Liwei is China’s first astronaut. He comes from Liaoning Province, and he has been an air force pilot(飛行員) since 1983. He was chosen from 14 pilots after many difficult tests.

The life of an astronaut is hard to imagine for many people. To put on a space suit takes 15 minutes with the help of others. Sleeping in space is not easy, either. He has to sleep in a special sleeping bag on the wall because there is no gravity. Yang can eat chicken and rice. It’s especially made to eat in space but it doesn’t taste nice.

“I’m feeling very good in space, and it looks wonderful here,” said Yang, “I have looked at our beautiful earth and I have recorded all that I have seen here.”

China has become the third country in the world to send a person into space after the former Soviet Union(前蘇聯) and the United States. China is now planning its next launch. Shenzhou VI will be into space within(在……之內) the next years, it may take three astronauts. We are all proud of our motherland.

It is easy for us to tell who our family members are, but do plants recognize(識別) their own family? Some do, scientists say, according to a report by Science News in early 2010.
Guillermo P. Murphy and Susan Dudley are two plant scientists from McMaster University in Hamilton, Canada. They did a few experiments with Jewelweeds, a kind of flower that grows in wet, shady spots. They found that the flowers seem to know their own flower family. In their experiments, Murphy and Dudley planted jewelweeds in pots with either siblings or strangers.
When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response(反應)suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food. Jewelweeds usually grow in the shade, where sunlight is not enough.
When jewelweed seedlings(幼苗)were planted with siblings, they grew a few more branches than they usually would if they were alone – but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete.
According to the Science News report, Jewelweeds are not the first plants that plant scientists have studied for family recognition. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach – where it may be hard to get fresh water. In that experiment, the scientists found that when sea rockets were planted with siblings, they tolerated each other. But when they were planted with strangers, the sea rockets reacted by working extra hard to grow lots of roots.
Dudley says this just because sea rockets, on the beach, get plenty of sun but struggle for water – so when they’re threatened, they compete for water. Jewelweeds have plenty of water but have to compete for sunshine, so they grow more leaves.
