The earliest maps were probably drawn in the Middle East. Some of these maps have1and they show us the people at that time thought the earth flat(平的).As time went by, the pictures became more detailed and maps were more2made. Later on, ancient Greeks(希腊人)used their3of math and science to make maps. Greek maps tell us the Greeks knew the world was 4.

    From simple pictures, mapmaking has turned into a science. Maps are made5 surveying(勘测)land. In the1900s, people around the world started to share information to make6maps. With the help of the photographs taken from the sky and space, maps are now more exactly made than ever.7the world is always changing, we will always need new maps.

    There are many types of maps, but almost all use8and pictures to describe what a place is like when the map is made. A map usually tells what the pictures 9. Some maps may show the whole world. A road map will help you know the10from one place to another. Other maps may use pictures to show the temperature and population in different places.

The Long March 5 Y3 is China's strongest rocket.

    China's biggest and most powerful carrier (运载) rocket roared (轰鸣) into space on Dec 27, 2019. The Long March 5 kicked off its mission (任务) at the Wenchang Space Launch Center in Hainan.

    The 57-meter-tall rocket, known as the Long March 5 Y3, is the tallest, strongest and most technologically sophisticated (技术复杂的) rocket in China. Since it is much bigger than China's other Long March rockets, people call it "Fat 5". The rocket is able to carry spacecraft (航天器) weighing up to 25 tons – roughly the weight of 16 midsize cars – into low-Earth orbit (近地轨道), China Daily reported. This payload capacity (有效载荷) is about 2.5 times greater than that of any other Chinese rocket.

    During the December launch, the Long March 5 successfully sent the Shijian 20 experimental satellite into orbit. At more than 8 tons, it is the heaviest and most advanced communications (通信) satellite built by China.

    The launch also tested key technologies that will be used to take the Chang'e 5 probe (探测器) to the moon, according to the China National Space Administration.

    The success of the Long March 5 launch was hard-earned. The rocket's first launch was carried out in November 2016 at the Wenchang center. A second mission took place in July 2017 at the same site, but failed to send a satellite into orbit. According to project leaders, in the two years since that failure, the rocket's research team held more than 600 seminars (研讨会) and carried out at least 1,000 experiments and tests to improve the rocket.

    "Compared with the Long March 5 Y2 that was used in the failed second mission, the new one has about 200 technical improvements, including changes to the engine design," Li Dong, the rocket's chief designer (总设计师), said to China Daily.

    The future missions of the Long March 5 will include a trip to Mars, taking back moon samples (样本), and placing parts of a manned (载人的) space station into orbit. 

    English playwright Arthur Wing Pinero said, "Where there's tea, there's hope." Similarly, a Chinese saying goes that "Firewood, rice, cooking oil, salt, sauce, vinegar and tea are the seven necessities to begin a day."

    Tea is, without doubt, welcomed all over the world. According to Statista, a German website for statistics (数据), global tea production reached about 5.8 million tons in 2018. It has become the most consumed beverage (饮品) in the world – after water, of course.

    According to the UN, tea is much more than just a hot drink. It's a big part of many cultures around the world. You probably know that people in China use top-grade tea to show respect when receiving important guests. Meanwhile, the British tradition of afternoon tea is an important part of that country's identity. Making Malaysia's pulled tea has become a sort of art form, where drinkers take pride in its entertainment aspects.

    Apart from its cultural significance (意义), tea is also a medicine, used from ancient times to modern day. "Tea is cold and lowers the fire," Chinese Ming Dynasty herbalist Li Shizhen once said. The health benefits of tea are still being discovered today: preventing heart disease, obesity and cancer have all been linked to drinking green tea, according to the National Center for Biotechnology Information in the US.

    Hot or cold, bagged or loose-leaf, tea is more than a drink – it's a social custom and also a magic medicine, a link to the past and a way of life.

    Maybe a lot of thin people will be worried about their health if the inside fat matters.

    Some doctors now think that the inside fat around important organs like the heart or liver could be as dangerous as the outside fat which can be noticed more easily.

    "Being thin doesn't surely mean you are not fat," said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have tested nearly 800 people with MRI to create "fat maps" showing where people store fat.

    According to the result, people who keep their weight through the food they usually eat rather than exercise are likely to have major deposits (堆积物) of inside fat, even if they are thin.

    Even people with normal Body Mass Index (体重指数) scores can have surprising levels of fat deposits inside. Of the women, as many as 45 per cent of those with normal BMI scores (20 to 25) actually had too high levels of inside fat. Men were nearly 60 per cent.

    According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the stomach first, but at some point, the body may start storing it elsewhere.

    Doctors are unsure about the exact dangers of inside fat, but some think it has something to do with heart disease and diabetes (糖尿病). They want to prove that inside fat does harm to the body's communication systems.

    The good news is that inside fat can be easily burned off through exercise or even by improving your eating habits. "If you want to be healthy, there is no other way. Exercise has to be an important part of your lifestyle," Bell said.

It's 8：00 am. A new term(学期)begins. This is the first class. 

Betty's new teacher comes into the classroom. She is a nice girl. "Good morning, boys and girls. Welcome to Class 3, Grade 7. I'm your English teacher—Helen Miller. You can call me Ms Miller or Helen. I'm from London and my phone number is 8336 001. I hope you like me. " 

"I like you, Helen，"one girl says. "My name's Kate King. I'm from Oxford. My phone number is 8975 002. " Then Kate gives a red flower to Ms Miller. 

"Helen, I love you，"one boy says. "I'm Dave Black from Cambridge. My phone number is 8790 041. "And Dave gives a red flower to Ms Miller, too. 

After that, two girls stand up and say, "We like you, too, Ms Miller. " Helen is surprised (惊讶的) to see them. They look the same. "We're twins from Liverpool，"one girl says. "I'm Lucy Brown and she is Lily Brown. Our phone number is 8790 032. " Then Ms Miller gets two red flowers again…
