When my brother and I were children, we spent a few weeks each summer in the countryside with our uncle. He was a geologist and loved to go on long walks to find stones to add to his collection at the university. More often than not, we followed him.
One day, we left early and this time, our uncle gave us two backpacks. "You can help me carry the samples, " he explained.
Sure, why not? The whole day, we walked around the countryside, and every now and then,our uncle put stones in our bags.We were a bit surprised that sometimes he also took some stones out from our bags, but thought he had just found better samples.
We reached the house in the late afternoon. The backpacks were so heavy that we were really tired out when we put them on the ground. Yet our uncle's backpack was half-empty.
"Why did you give us so many stones? " we asked. "I didn't. You did, " he said, waiting for a while before continuing. "You did not know it, but made you go through a little attitude test today."
"What do you mean an 'attitude test'?" we wanted to know.
"It is something someone once did to me. You see, I listened to every word you said. And whenever you complained about anyone or anything, I added a stone to your bags. And whenever you talked about something in an attitude of positive thinking, I took out a stone. And now look at your backpacks.
We did. They were full. "I hope you remember this little attitude test. You see, your negative thoughts are like stones. You carry them in your mind just like those stones in a backpack. The more negative thoughts you have, the heavier your mind is. So look at those bags and start paying attention to what you say and how you say things."
This little lesson was one of the most important I ever had. And I remember my uncle with great love for teaching us one of the most important lessons in life—the power of attitude.

________________________
If you look at the top of your phone ,you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" of your mobile network.But these symbols will become things of the past after 5G fully arrives.
On March 30th, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported.Shanghai has also become the first city in China to start testing 5G networks.Monaco became the first country in Europe to use a next-generation 5G mobile phone network based on technology from Chinese company Huawei.
It sounds obvious, but it’s important to understand just how much faster 5G is compared to current 4G speeds. 5G will not only be many, many times faster than your existing connection, it will be greatly faster than the broadband connection you have at home.
Now, 4G takes about 100 to 200 milliseconds* to send and receive data.But 5G will get it down to 1 millisecond or less.This big change will not only make our mobile Internet faster. It can be used in many other ways as well.
For example,5G will help to make self-driving cars safer.Today's self ﹣ driving test cars have one problem ﹣ lag.When the car"sees"an obstacle*, it sends this information to a data center and receives instructions. However, it takes time to send and receive this information. With this kind of lag, the cars might crash because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer,according to CNN.
5G could also be used to power the Internet of Things (IOT). This refers to a large online network that connects all things and people.Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your fridge could automatically* place an order online for eggs when it finds that there are no eggs left inside.
All in all, 5G will shape every type of technology that it touches. And you won't have to wait too long for that to happen. Though we’ve seen a lot of positive progress just in the last year, we still have a long way to go before 5G is anywhere near as common as 4G is right now.
1.From Paragraph ②, we can know that _______.
A.5G is widely used in Shanghai
B.it took lots of efforts to test 5G
C.China and Monaco is working on its 5G networks
D.5G would make it possible to take videos
2.The underlined word "lag" probably means " _______" in Chinese.
A.延迟 B.迷路 C.暂停 D.耗电
3.The fridge is mentioned to _______.
A.describe the importance of IOT
B.encourage people to try the new product
C.introduce how to use the Internet of Things
D.show 5G would make IOT more powerful
4.Which of the following would be the best title of the passage？
A.Can 5G Go Far？
B.How is 5G Changing Our Life？
C.5G is on the Way
D.China is Leading the World in 5G

There are lots of great watery wonders in the world, but some are disappearing.
The Dead Sea
At 430 meters below sea level, the Dead Sea is Earth's lowest point on land. It is popular for its wonderful buoyancy*. The high salt content makes swimming more like floating.
Now the Dead Sea is actually dying. People are using water from the Jordan River, which takes water away from the Dead Sea. Since 1930, its surfing area has reduced by almost 40 percent.
Venice, Italy
With waterways instead of streets. This "Floating City" has attracted visitors for centuries. But no visit to Venice is complete without a ride on one of its famous gondolas, human powered water taxis. Water creates Venice. But water will also kill the city.
Built on soft earth, Venice has slowly been sinking for centuries. Now, with
rising sea levels caused by human activities, it's sinking faster. The city may disappear in the next 100 years.
Great Barrier Reef
Covering more than 2,300 kilometers of Australia's northeast coast, Great Barrier Reef is the world's largest reef ecosystem, and an ideal place for scuba divers*. Thousands of colorful coral and fish make homes in the blue sea water. It's like a big underwater party!
Sadly, the party might be over soon. The reef is dying. Human activities are
changing the weather. Warming ocean water kills the coral, and this causes problems up the food chain. The reef system might be gone by 2030.
