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.

2 . TikTok has pushed a new safety update to its app that allows parents to take more control of their teenager’s accounts, as social media companies come under increasing pressure to make their platforms safer for children.

The company said that its Family Pairing now enables parents to turn off comments on their children’s videos entirely or limit them to friends only. Parents whose accounts are linked to their kids will also be able to set their accounts to private ones, turn off the search function for content or users, and limit who can see which videos their children have liked.

The Family Pairing lets parents see how long their children are spending on TikTok each day and limit the content they can see.

TikTok allows children to register (注册) and create an account if they’re over the age of 13. All they need to do is provide their date of birth. However, because TikTok doesn’t require registrants (注册人) to prove their identities, some children under 13 have registered by lying about their age, according to U.K. regulator Ofcom (英国通信管理局)

Alexandra Evans, head of child safety public policy for TikTok in Europe, told CNBC that Family Pairing has “put itself in parents’ shoes”since it was launched. “If we’re thinking of it as a toolbox, we want to offer more tools,” she said on a video call ahead of the announcement.

3 . Many people like to explore the Internet. Exploring the Internet is one of the most important activities of the day. The Internet brings the outside world closer to people’s homes. Some people say the world is smaller than before because of the Internet.

What’s going on in other countries? How do people live in faraway places? Is there a good sports game somewhere? What’s life like in the deepest part of the sea? If you want to answer all these questions, just come to the Internet. Of course, people can also learn through reading or listening to the radio. But with the Internet they can learn better and more easily. A lot of information can be collected at a great speed.

Can we go shopping without leaving home? Can we see a doctor without going to the hospital? Can we study without going to school? All these things seemed to be impossible, but now they have become true.

The Internet helps us to open our eyes. The Internet also helps to open our minds. The Internet often gives us new ideas. In a word, it helps us in many ways. Great changes have taken place in our life since the use of the Internet.

4 . Use Phones Respectfully

You probably spend more time on your smartphone than any other possessions. You take it everywhere—to school, to meals, and even to the bathroom.     1     But we have to learn to use our phones respectfully or at least without offending others around us. Here are some tips for smartphone usage. Take a look.  

Use “do not disturb” instead of “vibrate (振动)”.

Loud vibrations in your trousers are disturbing. People can hear your phone vibrate or not, depending on how violently it vibrates.     2    

Tell others what you’re doing.

Sometimes, you will be in a situation where you need to use your smartphone.     3    If you don’t, people will think that you’re either interacting with someone else or just getting bored.  

    4    

Respect others’ privacy such as text messages and e-mail senders by not letting what they type appear on the home screen of your phone when you receive a new message. While you’re at it, use a password to make sure the information stays between you.

Ask permission to swipe (滑动).

When people hand you their phone to look at a photo, this doesn’t mean you can look through all of their photo albums.     5    

From London’s Trafalgar Square to major cities across Britain, tens of thousands of British people have joined Chinese communities    1     (welcome) the arrival of the Chinese New Year.

In Manchester there was a Dragon Parade,    2     (lead) by a very breathtaking 54-meter long dragon, ending in Chinatown    3    people could enjoy a wide range of Chinese food and enjoy a spectacular fireworks show.    4     (celebrate) also took place in Liverpool, Birmingham, Lake District, Durham, Edinburgh, Leeds and Newcastle.

Academic Dr. Wu Kegang said, “ The Chinese New Year event in Britain is now     5    (impress) than ever and it is growing every year”.

On arrival in Britain 26 years ago from Guangdong, south China,    6     first thing Wu noticed was that Chinese New Year was celebrated    7    (main) in towns and cities with big Chinese communities. “You would go to London Chinatown and join your countrymen to celebrate,    8     to Chinatowns in places like Liverpool and Manchester for events almost only held for Chinese people,” Wu recalled.

“    9     is different now, is that we are seeing local communities all over the country taking part alongside their own Chinese populations,” he said. “ It is clear to me that the event will continue to grow in Britain where Chinese New Year    10    (earn) its place in the calendar of events so far.”

7 . New technology rules the whole world now. But I still remember when I was a child, I did not have a cell phone or a computer because it was not necessary at all in those days. The internet was not popular, and the touch screen technology was unknown.

At this time here in the US smartphone are really a need, especially for young and business people. There are many applications really useful like maps, dictionaries, e-mails and games.

For me, I use my smartphone to check the weather and to look for something on the internet and of course to keep communicating through calls and texts. Besides, I like music applications, GPS and Facebook.

Many tests have discovered that cell phones cause damages to us because they send out radioactive(具有放射性的) waves to our bodies and this could cause cancer.

Psychologists say that these devices can affect behavior and I believe everyone knows it is harmful to the eyes if we are sitting for a long time in front of computer. However, it seems to be difficult for us to give up, even if we know how bad it is for our health. The use of technology becomes more and more important in our lives.

I think the use of technology has brought us unimaginable things. If we use technology correctly, I am sure it would be possible to decrease the damage to our bodies.

Keep in mind that it is important not to focus only on technology, but to spend time with our families and people close to us.

Today’s festivals have a wide     1     of origins, including the seasons of the year, famous     2    , important events, and religions. The     3     festival is one of the most popular festivals and is celebrated in many cultures. Customs play a     4     role in festivals,   but they can change over time. For example, many Chinese cities no longer allow     5     during the Spring Festival, as they can increase air pollution. These days, festivals are becoming more     6    , with people spending more money on gifts. Festivals    7     people’s wishes, beliefs, faiths, and attitudes towards life. People are     8     to spend time with family, and to relax and enjoy life.
