The periodic table of elements is a common sight in classrooms,campus hallways and libraries. The mode periodic table arranges the elements by their atomic numbers and periodic properties(周期性). Several scientists worked over a century to assemble the elements into this format. 

In 1789,French chemist Antoine Lavoisiertried grouping the elements as metals and nonmetals. Forty years later,German physicist Johann Wolfgang Dobereiner observed similarities in physical and chemical properties of certain elements. He arranged them in groups of three in increasing order of atomic weight and called them triads,observing that some properties of the middle element,such as atomic weight and density,approximated the average value of these properties in the other two in each triad. 

A breakthrough came with the pu blication of a revised list of elements and their atomic masses at the first international conference of chemistry in Karlsruhe,Germany,in 1860. They concluded hydrogen would be assigned the atomic weight of 1 and that the atomic weight of other elements would be decided by comparison with hydrogen. For example,carbon,being 12 times heavier than hydrogen,would have an atomic weight of 12. 

In 1869,Russian chemist Dmitri Mendeleev created the framework that became the moder periodic table,leaving gaps for elements that were yet to be discovered. Mendeleev predicted the properties of some undiscovered elements and gave them names such as"eka-aluminum"for an element with properties similar to aluminum. Later "eka-aluminum"was discovered as gallium. 

German chemist Lothar Meyer produced a version of the periodic table similar to Mendeleev's in 1870. He left gaps for undiscovered elements but never predicted their properties. The Royal Society of London awarded the Davy Medal in 1882 to both Mendeleev and Meyer. The later discovery of elements predicted by Mendeleev verified(证实)his predictions and his periodic table won universal recognition. In 1955 the 101st element was named mendelevium in his honor. 

On UNESCO website,it wrote,"The Periodic Table of Chemical Elements is more than just a guide or catalogue of the entire known atoms in the universe;it is essentially a window on the universe,helping to expand our understanding of the world around us. "

(1)、What is the breakthrough at the conference in Germany?
A、The atomic weight of carbon was calculated by scientists. B、A brand-new periodic table was published at the meeting. C、The elements in the table were rearranged by the properties. D、The atomic weight of elements was quantified based on hydrogen.
(2)、How did Mendeleev contribute to the modem periodic table?
A、He made it more complete. B、He made it easier to understand. C、He was the first to arrange the elements by atomic masses. D、He discovered many new properties of some known elements.
(3)、What is the significance of the discovery of the periodic table?
A、It is a window into chemistry. B、It is a helper to learn about history. C、It is a guide to exploring the microworld. D、It is a description of school curricula's history.
(4)、How is the text developed?
A、In order of the elements' importance. B、By following the time order. C、In order of scientists' achievements. D、By making comparisons.

    Most kids go to school during the day and come home to their families or caregivers at night.Sometimes kids can't go home every night so they board or live at school during term-time.

    Whatever the reason for going to boarding school, living with a group of people is very different from living with your family.You have to learn to get on with others, be responsible for looking after your own stuff and follow the rules that are there to make everyone's life pleasant and safe.

The following are some tips from boarders.

    "Remember that the other new students are probably as shy as you are.If you don't talk first and try to make friends, it may not happen."

    "Don't hold things back inside you.The more you talk, the easier it gets.You can talk to older boarders as well as adults.They understand what you are feeling—they've been through it too."

    "Be respectful of others' space and give them privacy.Having people around all the time means you don't get much time to yourself."

    "Join in sports and other afterschool activities.You'll meet lots of new people who are interested in the same things as you.And keeping busy will help you get over feeling homesick."

    "If you are a weekly boarder or go home most weekends it can be harder to make friends, so see if you can organize to stay in for a weekend."

    "Make friends with non-boarders too.It's good to visit someone's home sometimes."

    "Boarding has its ups and downs, you get homesick and sometimes the food is not that great but most of the time it is like being in one big family.You make friends that you know you'll keep for the rest of your life."

    Now Glen doesn't like to think what might have happened had he and his best friends, Ray Wightman and Chris Johnson, picked their usual path along a rocky outcrop-the faster route to Johnson s home on Triangle Mountain. They were heading there after school that day-April 14, 1999-to play street hockey in Johnson's driveway. There were other lucky twists, too: not stopping at the shops to get a cola« as they usually did; hearing the strange cry.

    It was 3:30 pm. The three teens were laughing and talking when suddenly they heard a strange cry coming from the ditch(沟渠) across the road. Crossing to take a look, they found an Adidas gym bag sitting deep in the icy water. They climbed down the steep bank and pulled the bag from the water, expecting to find abandoned cats or dogs inside. Instead, the boys found a trembling newborn girl. Wrapped in an old blanket, wearing a thin nightshirt, she was almost blue, her lips shaking from the cold and her crying.

    The boys couldn't have been more astonished. They knew this one needed to get warm and dry, although they didn't know much about babies. Ray dug through his gym bag and wrapped her in a T-shirt. “We didn't know what to do,” said Glen. “I didn't think any of us had really held a baby before.” So the three stood beside the ditch, dumbfounded, taking turns to hold the baby to their chests to keep her warm.

    “We knew it was no use walking up to Ray's house, because his mum was working and no one would be home. We figured we'd have a better chance just staying by the road and flagging down someone.” So they stood there and waited.

    A car drove by and the boys caught the driver's attention, telling her that they had found a baby. The woman then drove off to get help. When the police and ambulance came 20 minutes later, the teens were told the baby was probably two or three hours old and had perhaps been in the ditch for an hour or more. They were also told that they had saved her life and that given 10-20 minutes more in the cold water, she probably would be drowned.

    Traveling abroad for leisure is becoming more and more popular for Chinese. The UK is high up in the list of places that the Chinese want to visit. There is a sense of mystery about the UK: it's often the images of England's green parks, countryside and Victorian houses that people point to as an alternative to polluted, overcrowded cities such as Beijing and Guangzhou.

    The capital is viewed as modern and dynamic, while being filled deep with history. When asked what other images are thought of by the UK, the reply is often "the Queen, tea and Oxbridge". So what's stopping them actually coming? Sebastian Wood, the British ambassador in Beijing, has described the UK as a "fortress", and while this is perhaps an exaggeration (夸张), Britain does have a reputation as a country that is harder to access.

    The main problem for Chinese tourists is obvious. Although visa applications are now completed online, visitors are still required to visit one of 12 UK centers across the country for a face-to-face interview and fingerprinting. If you don't live near one of these centers already, you'd have to travel some distance to get there.

    Another problem is also to be mentioned. If travelers from China visit the UK, they also want to cover as much ground as possible. But the UK is not included in the Schengen visa, which allows access to a host of 26 European countries such as France and Germany. So it makes the former seem less worth it.

    There is also the issue of cost:£47 for a Schengen visa, £82 for the UK. On top of this, the UK is viewed as stricter in its handling of visas compared with the rest of Europe, fed by urban legends of rejected applications. In the end, the decision comes down to one question: Is Britain worth a visit?

    When I was about twelve, I headed to a restaurant for dinner with my family. It was winter, and on that night, the wind was really blowing hard.

    As my mom and I headed to the restaurant from our car, a girl about my age and her mother came up to us. They asked if we had any spare change (零钱). My mom right away asked where they lived. They pointed to an old car in a parking lot across the street. The girl said there were six of them living in that car. My mom said she had something to do after handing the people a few dollars. She sent me inside the restaurant with my dad and my three siblings (兄弟姐妹). But she didn't come. Later, I found out she had gone home and put all the food in our cupboards (食橱) into a few bags. Then, she brought that food over to the car and handed the bags to the family. I wasn't there when that happened, but I can only imagine the joy it brought to those people.

    A few days later, when I actually found out about what she had done, I asked her why she helped those people. She told me that they were not lucky. I remember the face of that girl who had asked us for change. She was the same age as me, yet we looked so different.

    Here I stood, dressed in almost new clothes, headed to eat in a restaurant and then back home to the bedroom I shared with my younger sister. I remember thinking that the other girl didn't have any food to eat and she was heading back to a cold car shared with five other people.

    After painting this picture in my mind, I understood why my mom had done what she did. I will never forget what she did that night, and how she taught me one of the best lessons I ever learned.

Gardening 380 Kilometers above Earth Astronauts have to go through physical, psychological, and technical training. They also go through training in how to care for plants. These "astronaut gardeners" share their work and living space with plants.

Taking seeds and plants along on a trip isn't a new idea. As space trips become longer, it will be necessary to grow food in space. {#blank#}1{#/blank#} Because of this, it's not practical to send everything needed for a long journey, only to be used once and thrown away.

Plants can serve many uses on a space journey. They can provide more fresh things. {#blank#}2{#/blank#} Also, plants can help to make air quality better because they produce oxygen. They can improve the quality of the air inside the spacecraft—the only air the astronauts can breathe.  {#blank#}3{#/blank#} Due to the lack of gravity in space, the oxygen that the plants produce stays around the plants. This can actually kill them, so fans are needed to circulate the air. Without gravity, roots don't "know" to grow down, leaves don't "know" to grow up, and water doesn't easily travel up the roots to the leaves. {#blank#}4{#/blank#} Besides, soil is too heavy to send to space, and special liquid gels (胶) are used to help plant growth.

Scientists are also working on the plants themselves. They are trying to make plants grow more rapidly and grow with less water and light in space, and they are looking for ways to make plants more resistant to disease. {#blank#}5{#/blank#} Imagine that deserts may one day provide lots of fresh food for local people, saving transportation costs. Similarly, plants that are resistant to disease could provide an important food supply. With the world's population now at seven billion (十亿) people, our astronaut gardeners may help discover ways to feed those billions.

A. Every plant grown in space must have several uses.

B. However, there are challenges with growing plants in space.

C. Such methods may result in improvements back here on Earth.

D. The cost of taking anything into space is about $22,000 per kilogram.

E. Specialized containers are being developed to help the plants grow correctly.

F. Astronauts will welcome the addition of fruits and vegetables to their diet of dry foods.

G. Currently all oxygen is taken aboard in tanks and then caught again so it can be reused.
