Space tour is not all about rockets—large space balloons can do it too! The company HALO Space in Spain completed the first test flight of its balloon in December, 2022. This means another company joined the competition of making space tour a reality.
During the test flight, the balloon reached an altitude of 37 kilometers where passengers would be able to look at the Earth from the blackness of space, according to Daily Mail. When the flights are available, the company aims to carry 3,000 passengers on 400 trips every year.
How does a space balloon work? The balloon is usually filled with helium or hydrogen, which are both much lighter than air, and it flies up.
According to NASA, the balloon is filled with the amount of gas that will give it enough lift to get off the ground and rise. As it rises, the gas inside the balloon grows larger.
The balloon stops when the density of the gas inside and the air outside is about the same, it begins to fall down as gas goes out slowly.
So the whole trip is not intense. The Space Perspective in US says that the trips are about relaxation. The balloon rises slowly at 12 miles (about 18.3 kilometers) an hour, and it takes about two hours to get to the 37 km altitude. It also takes another two hours to go back to the land.
Since its successful test flight in June 2022, Space Perspective Company started selling tickets for spaceflights in 2024—and it has already sold out. The company now buys ships to turn them into “floating spaceports”, reported Daily Mail. By lifting the balloon from ships on the sea, there will be more chances to enjoy the tour, such as flights at sunrise and sunset.

【推荐1】The Outback is a large desert (沙漠) area of Australia. Very few people live there and temperatures can be very high-about 50℃ in summer! Read the advice before you go there.
Do’s Take enough water. There are few places for you to find water in the Outback. You can live for many days without food but not without water! Use sunblock (防晒霜).

You should also tell friend or your family where you are going and when you are planning to get there. |
Don’ts Don’t depend on your phone. Some of the areas in the Outback are very far and there is no signal (信号). Don’t worry too much about snakes.

【推荐3】We are told to travel the world, discover new things and meet new people. But there is one problem. Even paying for a bed for the night makes you feel as if broadening your minds requires plenty of money — and for students, that is not always possible.
The words “youth hostel” (青年旅舍) for your parents might mean smelly dormitories (寝室)with six strangers, or having to pay for messy towels, and dirty pillows. However, youth hostels nowadays — especially the ones in China — are wonderful.
In Chengdu, my friend and I were served free coffee and the people working there gave us suggestions of the best ways to visit the pandas and the best hotpot restaurants in Sichuan.
In Yangshuo, I made friends with a German and two Americans. We rented bikes from our hostel owner and rode around the city. When it rained, the hostel owner lent me his raincoat. One night the housekeeper cooked us a great meal of homemade Chinese dishes.
Never did I pay more than 50 yuan for a bed. Sometimes, even though I had booked a “dormitory”, I ended up in a private room by myself. Because these are “youth hostels”, you can meet lots of students like yourself, all of whom want to get the most out of a small budget (预算).
The best two websites for finding and booking hostels are www.hostelbooker.com and www.hostelworld.com. Not only do they allow you to organize everything online, they also give each hostel a score depending on how the guests feel when they remain there.
Travel the world, discover new things, and meet new people — all for the price of a cup of coffee? Just choose the city and now you go!

Most students go to school by bus in America. It’s common to take the subway to school in some cities. But in small towns or cities, it is still popular to walk to school.
In America, the school bus has the same color—yellow. It’s very convenient(便利的)because it can take students right to their schools. It can also give students time to talk with their friends. However, the school bus is usually slow and doesn’t come on time.
The subway, in many cities, can get around quickly. However, it’s not the cheapest and is crowded during the rush hour. Another disadvantage of the subway is that the stops are not so close to the school, and students have to walk a long way or take a bus from the subway stop to school.
For many students, who live close to school, walking is the best. It’s free and good exercise. But if your schoolbag is full of books, or the weather is too bad, it’s not a pleasant way to walk to school.

【推荐2】If you go to London you will see a lot of buses and cars on the road. You’ll also see lots of bikes because more and more people travel by bike. Why?
There are a lot of reasons for this. First, it is very cheap to buy a bike. And then people have to wait for a bus for half an hour. Finally, after you get on the bus, there are so many other buses and cars on the road that the bus moves very slowly.
I traveled to work by bus for about four years. l often arrived at work late and felt tired. Then one day, about two years ago, a friend of mine said, “I go to work by bike every day. Please come and join me.” “But my bike is old, and there are so many buses and cars on the road. I’ll feel frightened.” I answered. “You needn’t feel afraid. If you follow me and we ride slowly, you will be fine,” he said.
The next day I bought a new bike. Although we went slowly, we arrived at work soon. It took 40 minutes to go to work by bus, but only half an hour by bike.
Now I like riding a bike to work. I ride very slowly but I arrive at work quickly. I’ve saved a little money and I feel healthy. Many people think my idea is good and maybe you can see more bikes on the roads in London.

【推荐3】Many people like to take a trip by plane, but I don’t like it because an airport (机场) is usually far from the city. You have to get there early and wait for hours for the plane to take off (起飞) and it’s often late. You can’t open the windows. You can’t choose the food. Planes are fast, but it still takes you hours to go out of the airport and into the city.
I like traveling by train. I think trains are safe. The stations are usually in cities. When you are late for a train, you can catch another one. You can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time.
I also like cars. You can start your trip when you want to, and you don’t need to get to a railway station or a bus stop. Also you can carry many things with you in a car. But sometimes there are too many cars on the road.

In 1994, a Japanese Masahiro Hara invented the Quick Response code(QR 二维码)as a way to increase the amount of information that could be stored on a paper label. Before this, one-dimensional(1D) barcodes had already been used since 1974 when the first barcode(条形码) was scanned in a supermarket in USA. The first barcodes consisted of two parts: the barcode and the 12-digit number. But the two-dimensional (2D) code made by Mr. Hara can hold as much as 7,000 digits or 4,000 characters of text, including all Japanese characters. Many books have QR codes on their back cover which provide information such as the price, the author and the publisher.
Around 2006, Wang Yue and his team developed the Hanxin Code which can also encode Chinese characters. Short Hanxin Code, instead of long Chinese names, are now widely printed on the large quantity of shoes on trucks and ships. In 2014, Wang Yue's company produced its first self-service QR code reader -- the Smart Box. Now it has become the most popular offline payment in China.
QR codes can be easily read with any mobile phone that has a camera. So they are now widely used in factories and supermarkets, on various tickets and restaurant cashier tables. On 14 February, 2020, a QR code called 'Health Code' is used in Hangzhou for people to quickly report their health status. Firstly, find an app named Alipay and scan the QR code included. Secondly, provide your name, phone number and ID number. Thirdly, answer some questions about your health status and whereabouts. Then you will get the 'Health Code' with different colour, green for "being healthy". Only with an updated green code, you may be allowed to enter or leave Hangzhou. On 21 February, 2020, a QR code is also used by Ms. Tang to inform her students about the course arrangement.

【推荐1】Do you have good friends? Do you sometimes feel so close to them that they are like family to you?
It turns out that this isn’t just an expression. A study by Yale University has found that you and your friends have more genes (基因) in common than strangers do. Researchers looked at the genes of 1,932 people and compared them in pairs of unrelated friends and strangers. They found that friends have 1% of genes that match.
“1% of genes may not sound like much to the layperson (外行), but to geneticists (遗传学家) it is a larger number,” Professor Nicholas Christakis of Yale University told Discovery News. In fact, this is the same amount of genes you share with your fourth cousins, those who have the same great-great-great grandparents as you.
So do you happen to become friends with people who share your genes? Not at all. In fact, it is evolution (进化) that brings you together.
“People who share certain genes also share skills and have similar likes and dislikes,” researchers said. In ancient times, it was important that people who were alike stayed together. For example, people who had a similar susceptibility (易感性) to the cold were more likely to help each other build a fire, giving them a better chance to stay alive.
Researchers also found that among all the genes studied, those producing a change in sense of smell were the most similar in friends.
This is probably because people who smell things in the same way are more easily drawn to similar environments. For example, people who like the smell of coffee may hang out at cafes (咖啡馆) more often and as a result are more likely to meet and become friends with each other.
With their findings, the team has developed an interesting test called the “friendship score”. It can help tell how big the chances are that two people will be friends by studying their genes.
So, here is a question for you: would you like to take this test and know in advance (提前) who your friends are going to be, or would you still prefer to learn about it by yourself and let time be the judge?
1. From the passage, we know that friends _______.A.look like our cousins | B.share 1% of genes with us |
C.feel close to our family | D.can help us when we feel cold |
A.study how ancient people dealt with the cold |
B.predict that similar environments lead to friendship |
C.prove that it is evolution that brings friends together |
D.explain why ancient people gave each other chance to keep alive |

【推荐2】Nowadays we spend a lot of time on our smart phones every day. Many of us have become so reliant on them. However, it is bad for us to use them too often.
A study shows that smart phone owners usually start to use their phones early in the morning. They check personal emails and WeChat. And before they get out of bed, many people often check the weather, read the news, and send a message or two to friends. After getting up, they often take photos of food, themselves and even whatever they can see with their phones. They share their photos with their friends. The research finds that users pick up their phones more than l,500 times to do different tasks in an average (通常的) week. And they are on their phones for three hours and sixteen minutes a day. That is to say, people use their phones for almost one full day each week.
It takes much time to use phones and it’s also bad for our health. Many people stay up late to play with phones. Surely, it will influence (影响) our sleep. Without using the phones, many people will feel sad. Many owners also find they use their phones without realizing they’re doing so.
