Although I didn’t have any interest in being a school bus driver, I became one. Many years later, I was still working on the school bus. There are so many good reasons. Firstly, the talk brought me different kinds of information. I also got to hear all the family secrets of the newcomers. I have a toy bear who was a great comforter(安慰者) for the little ones. The kids got to look after him on the trip to school and he waited patiently for them to get on for the trip home. 
Our bus would often pass a place where we could see some alpacas (羊驼) in front of a farm house. Little Michael would cry excitedly from the seat, “Look, Miss! Look at the camels!” He used to put his head out of the bus window. When I warned him that a little insect would come into his nose if he wasn’t careful, he smartly gave up the habit.
I remember a little girl got on the bus one morning 5 years ago and sobbed(抽泣) all the way to school. We arrived at the school gate. As she waited to get down the bus, she threw her arms around my neck and cried that her grandfather had died the night before.
A school bus driver needs to keep one eye on the road and the other on the mirror to watch what the little ones are doing down the back.
Now, it’s important to think how many lives I’ve been responsible(负责的) for, and how many kilometers I’ve driven in order to get my passengers home safely during the 20 years. I’ve enjoyed it, but it’s time to rest and park my school bus.When did the writer begin to be a school bus driver?

Many objects in the universe are invisible ，but they send radio waves．The radio telescope *thus appeared，and it is considered one of the greatest inventions in the twentieth century．Reber built the world's first radio telescope in 1937．Ryle and Hewish developed radio telescope systems for the location of weak radio sources，and they shared the Nobel Prize for Physics in 1974．
A radio telescope is usually made up of：
•One or more antennas to collect the radio waves．Most antennas are made in the shape of a dish to collect and reflect *the radio waves to the sub﹣reflector，in the same way as a curved mirror focuses visible light to one point．
•A receiver and amplifier to receive the radio waves from the sub﹣reflector，and make these weak radio waves strong enough to be recorded and turned into electronic signals *．To make an amplifier sensitive enough，it is usually cooled to very low temperatures（e．g．as low as ﹣270℃）．
•A recorder to keep a record of the electronic signals．Most radio telescopes today keep the signals to the computer's memory disk for astronomers to analyze later．
Radio wavelengths are much longer than those of visible light．and the radio waves from deep space are always weak．To catch these waves，radio telescopes usually have huge antennas．The sizes of most antennas in use today are around 50 to 300 metres in diameter． The antenna of FAST in Guizhou，China，the latest and largest radio telescope in the world，is 500 metres in diameter，as large as the size of 30 football fields．
To avoid interferences， and keep the telescopes sensitive，radio telescopes are built in places where there are no human radio waves or electronic signals．For example，FAST is 5 kilometres away from the closest village and 25 kilometres away from the nearest town．
Radio telescopes create pictures of the sky，not in visible light， but in radio waves．This is extremely useful，because there are objects that can't be seen，objects that we wouldn't even know were there without radio telescopes．

Have you ever jumped on a trampoline？ Today many people use it for exercise．
Back in the 1980s，researchers found that jumping on a trampoline was a good way to help astronauts regain their strength．Actually，trampolining has many advantages．It helps bones*and muscles*grow and improves your balance by stimulating *the inner ear．It is especially useful for increasing flow of the lymphatic system，which helps your body get rid of harmful toxins．Trampolining has benefits similar to those of running，but without too much stress on knees and ankles．
If you would like to start trampolining，you may first need to ask a doctor to make sure it's a safe activity for you．It's easy to find an inexpensive trampoline， but it should be well﹣made and strong enough to support your weight．To avoid accidents，some trampolines have a safety net around them．Remember： whenever you are on a trampoline，be careful not to jump near the edge of it．
Here are a few exercises for beginners；
•High Knee Lift．Raise one knee at a time．Lift your knee higher than you usually do when you are running．
•Star Jump．Jump into the air and spread your arms and legs into a star shape．As you gain more confidence，practice more difficult levels：
•Tuck Jump．At the top of your jump， bring the knees to the chest*，with the arms holding the legs．
•Pike Jump．Jump high，bring the legs up，and point the toes *forward．Touch your toes with hands．
There are many more exercises you can try．Happy trampolining!

Tourism （旅游业）is one of the world's largest industries． Many countries depend heavily on tourism as an important part of their economy（经济）， while other countries﹣such as some of the smaller Caribbean island nations﹣are almost completely dependent on tourism．
Despite its economic advantages，tourism has disadvantages， too． While countries spend millions attracting tourists， they are also under the pressure that tourism brings．
One of the biggest problems is environmental． The building of roads and hotels can quickly destroy those very beautiful places． Development on wetlands，for example， influences wildlife； forests disappear as they are cleared to make way for buildings and to provide fuel （燃料）． In addition， the tourist industry also puts a huge pressure on water people need． In dry Mediterranean areas， tourists use almost twice as much water as local people when swimming in the pool．
Tourism is also responsible for producing plenty of waste． Cruise ships in the Caribbean produce a lot of rubbish﹣more than 70，000 tons each year． It even has an influence on places far away like the Himalays，the word's highest mountain， which has more than 100 tons of rubbish sitting on it．
In spite of those problems， tourism can be good for communities and the environment． The park﹣entrance fees（费用）are paid for the protection of places of interest or the animals． What's more， tourism brings people closer to nature， and can give them a better understanding of the environment and the result of destroying it．This leads to pressure on local governments to protect these beautiful areas，and can result in the protection of endangered plants and animals． Also， it can provide people with more opportunities to find jobs in the tourist industry．
Although tourism has many advantages， it clearly has a bad influence as well． The challenge for local and national governments is to manage tourism so that communities can benefit economically， and yet at the same time， make sure that the tourist areas are kept for all to enjoy．

Brooke wanted a dollhouse 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 home assistant powered by AI（人工智能）．And it made Brooke's wishes come true． A few days later， much to her parents' surprise， a﹩170 dollhouse and four pounds of cookies showed up． They ate the cookies and gave away the dollhouse to a local hospital．And that's not the end of the story． When a news reporter told the story of what happened on TV， Alexa devices（设备）in many listeners' homes woke up and tried to order dollhouses!
Alexa isn't the only AI willing to serve you． Apple HomePod has Siri， Google Home has its Assistant， and the upcoming Galaxy Home device will have Bixby． People who
have these devices use them mainly for listening to music， checking the weather， and setting timers． According to a report from The Information， nowadays voice shopping is rare． But many scientists predict
a boom（增长）in voice shopping in the near future． Is that a good thing？
▲． You can shout out an order as soon as you think of it， even if you are cooking，cleaning， or driving． In addition， people with disabilities who are unable to use a keyboard or mouse can shop without any help．
But voice shopping has its disadvantages． Unwanted dollhouses aren't the biggest problem． It's usually very easy to cancel an order or return products． The thing that worries some people 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 order． When they hear it， they start recording the conversation． Some have worried about what happens shopping habits？ And what if someone hacks（入侵） the device？ The CIA found a way to hack smart TVs to turn them into spies that listen all the time． Others could do the same with any smart device．
