IS EXPLORING SPACE

A WASTE OF TIME AND MONEY?

Countries around the globe are spending billions of dollars and lots of time on various space missions, whether to Mars or other planets much further away. Some people argue that we should stop wasting time and money exploring space. Instead, we should feed the world’s poor and find immediate solutions to other problems, such as pollution and fatal diseases. However, others feel this is a shallow view which fails to realise how exploring space helps us.

Firstly, exploring space has already made a difference in the fight against world hunger. It has directly resulted in the many satellites that now orbit Earth. A number of the satellites record data on land and weather patterns. Then the data is transmitted to scientists on Earth. After careful analysis, the scientists can provide useful recommendations and advice for farmers. As a result, space-based science has helped farming in its efforts to grow enough food to feed Earth’s increasing population.

Secondly, space exploration has already promoted technological improvements that benefit us all. High-end products around the world are made to a higher standard now because of advanced technology which was first created to meet the requirements for space exploration. For example, space technologies have helped the research and development of different types of new material. They have also helped companies make better heart monitors and other machines that doctors regularly use. Today, space technologies are widely used in all kinds of industries, and everyday products such as GPS, memory foam pillows, and smartphone cameras are changing our lives.

Finally, sending astronauts into space has helped people to think about the world’s problems and even to find ways to solve them. Seeing pictures of our planet as an island in a black sea made people realise that our planet’s resources are limited. In order to provide for such a rapidly increasing population, scientists are trying to find other planets that could one day be our new home. The greatest attention at present is on Mars because it is closer to Earth. In the future, humans may live on both planets.

In closing, exploring space provides the world with many different benefits. Therefore, it should continue so as to provide new and better solutions to people’s short-term and long-term problems.

5 . Brooke wanted a toy and some sugar cookies. So the 6-year-old asked Alexa to get them. Alexa wasn’t her mom or babysitter. It was a voice-activated (声控的) home helper powered by artificial intelligence (AI). Alexa comes with the Amazon Echo device (回波装置). And it made Brooke’s wishes come true. After being reported on TV, Alexa devices in many listeners’ homes woke up and tried to order toys!

Alexa isn’t the only AI willing to order up treats for you. Apple Homepod has Siri, Google Home has its Assistant, and the upcoming (即将来临的) Galaxy Home device will have Bixby. People who own these devices use them mainly for listening to music, checking the weather, and setting timers. According to a report from The Information, people don’t often do voice shopping. They do it mainly to order simple things like paper towels. But many experts predict a boom (繁荣) in voice shopping in the near future.

Convenience is the main benefit of voice shopping. You can shout out an order as soon as you think of it, even if you’re cooking or driving. Besides, people who are unable to use a keyboard or mouse can shop without help.

But voice shopping has its disadvantages. Unwanted things aren’t the biggest problem. It’s usually very easy to cancel an order or return items. The surprising thing is that these assistants are always listening. They have to be able to respond when you want them. So they listen for “Alexa” or “OK Google” or another command. When they hear it, they start recording the conversation. Some have worried about what happens to these recordings. Should companies be allowed to use them to learn about people’s shopping habits? What if someone hacks (非法侵入) the device? What if someone hacks smart TVs to turn them into spies that listen all the time?

9 . Miles was born in Alton, a city on the Mississippi River in Illinois on May 26,1926. Miles’s father was a dentist, while his mother was a music teacher. Miles had a good childhood, catching fish and riding horses with his older sister and younger brother. He was known as a naughty boy in school.

He recalls his story, “By the age of 12, music had become the most important thing in my life.” His mother, a violinist herself, dearly wanted her son to play the violin. But brass(铜管乐器) was Miles’s calling, and he remembers arguments between their parents as his dad overruled his mom to fight his son’s corner. He received his first trumpet(喇叭) in 1935 and began weekly music lessons with his father’s friend Mr Elwood, his lifelong teacher.

Talking about his schooldays, Miles said that Mr Buchanan was the biggest influence on his life. He was the person who took Miles all the way into music at that time. He wanted to be a musician that he had dreamed.

When he was 16, Miles met his girlfriend,Irene Birth.Although she was a beautiful young woman in many ways,it was her easy-going character that attracted Miles. At the weekends,Miles and Irene would take the bus over the Mississippi River to St Louis to watch movies and go dancing. Although Miles was too shy to really enjoy dancing, he always felt confident when he danced with Irene.

When he turned 17, she persuaded him to ask for a job in his band. It worked. Joining the band was a breakthrough for Miles, and marked the time when he first began to write and arrange music.

10 . One year, a college in the United States announced that it would offer a lot of money for the pure white marigold (金盏花). The high reward attracted so many people, but in nature, besides golden, the marigold is brown, and it is not easy to get the white one. So after they were excited for a time, many people had forgotten the announcement.

One normal day after 20 years, the college received a letter and 100 seeds of pure white marigold. It was an old woman of over 70 years old. Some experts in the college doubted it, but in order not to let her down, those seeds finally took root (根) in the earth. The miracle appeared after one year; the field was covered by pure white marigold.

Therefore, the old woman who was always unknown to the public became a new focus.

The old woman was a flower-lover. When she read the announcement 20 years ago, she got very excited like others. But her eight children were totally against her decision. After all, a woman who never knew the seed genetics (遗传学) couldn’t complete what the experts could never do, so her thought was only a day dream.

Still, the old woman didn’t change her mind and went on working. She planted some of the most common seeds and took good care of them. A year later, when the marigold came out, she chose one faintest (最暗淡的) from those golden and brown flowers and got the best seed. The next year, she again grew them and chose...Day after day, year after year, through many seasons, the old woman’s husband died, her children flew far, a lot of things happened in her life, but only the wish to grow the pure white marigold took root in her heart.

Finally, after 20 years on the day we all know, in the garden she saw a marigold, which was nearly white, but as white as silver or snow.

A problem even experts couldn’t deal with was solved by an old woman who didn’t understand genetics. Was it a miracle (奇迹)?

To take root in the heart, even the most common seed can grow into a miracle!
