A girl became a volunteer in the activities of Deathbed Care, which meant visiting and taking care of a patient suffering from an incurable disease with days numbered.

    The girl was assigned to look after an old man suffering from cancer whose children lived abroad. Their living conditions were not satisfactory while the old man had a lot of savings. She was expected to comfort him and keep up his spirits.

    Every Saturday the girl came on time to keep him company, telling him stories. When he was having an intravenous drip (静脉滴注), she would help massage his arms. The doctor found the patient much improved mentally. The old man began to involve himself actively in the medical treatment and he seldom shouted at others.

    But something that happened made the doctor uneasy and puzzled. Each time the girl left, the old man would give her some money. The doctor did nothing to interfere (干涉), unwilling to offend the old man. A month later the old man showed evident signs of decline after suffering coma (昏迷) a few times.

    When rescued from the latest coma, the old man told the doctor his last wish, “I have deep sympathy for the girl. Will you be kind enough to help her finish her studies？”

    But the doctor knew that her family was well­off and she had no difficulty pursuing her studies.  Sometimes she even came to the hospital in her father's car.

    When the girl came at the weekend after the death of the old man, the doctor told her the bad news. She was very sad and burst into tears. Then she handed $ 500 to the doctor, saying, “The old man had all along thought I came to do the job because of poverty. He gave me money so that I could continue my schooling.” Now he got the answer to the puzzle. In the last period of his life, the old man found it a real pleasure to be able to help a girl badly in need.

    In 1917 Orville Wright predicted that “the aeroplane will help peace in many ways —in particular I think it will have a tendency to make war impossible.” Earlier in 1904, American journalist John Walker declared, “As a peace machine, the value of the aeroplane to the world will be beyond computation.” This wasn't the first grand promise of technology. In that same year Jules Verne announced, “The submarine(潜艇) may be the cause of bringing battle to a stoppage.”

    Alfred Nobel, sincerely believe his dynamite(火药) would be a war obstacle: “My dynamite will sooner lead to peace than a thousand world conventions(公约).” Similarly, when Hiran Maxim, inventor of the machine gun, was asked in 1893, “Will this gun not make war more terrible?” he answered, “No, it will make war impossible.” Gugliemo Mareconi, inventor of the radio, told the world in 1912. “The coming of the wireless time will make war impossible, because it will make war ridiculous.” General James Harbord, chairman of the board of RCA in 1925, believed, “Radio will serve to make the concept of Peace on Earth, Good Will Toward Men a reality.”

    David Nye, a historian of technology, adds to the list of inventions imagined as abolishing war forever and leading to universal peace the hot-air balloon, poison gas, land mines and laser guns.

    It is not that all these inventions are without benefits—even benefits toward democracy（民主）. Rather, it's the case that each new technology creates more problems than it solves. “Problems are the answers to solutions,” says Brian Arthur.

    Most of the new problems in the world are problems created by previous technology. These problems are nearly invisible to us. Every year 1.2 million people die in automobile accidents. The technological transportation system kills more people than cancer. Global warming, environmental poisons, nuclear terrorism, and species loss, are only a few of the many other serious problems troubling people.

    If we embrace(拥抱) technology we need to face its costs.

    A “Gap Year” is a period of time when a student takes a break before going to university. It is often spent travelling or working. It can give young people useful learning experiences and new skills.

    Gap years are popular with European and Australian students, but remain less popular in America. However, in recent years, more and more American students are preparing for college by taking a gap year. The advantages of taking a gap year are as follows：

Learn about the World and Yourself

    Although you don't have to go abroad to experience gap years, most gap year students catch the chance to travel abroad. You are able to work out who you are and what you are for. The experiences of different cultures offer you interesting lessons. You can learn more about the world and get to know yourself better.

 Face Challenges and Have Fun

    A gap year is not only a time to take a vacation, but also a time to face challenges. Gap year students usually work, volunteer or take service projects. You have to learn how to get along in the real world. This process isn't always easy, but it is an important part of growing up. Only in this way can you enjoy life and have fun.

Save Money and Improve Your College Admission Chances

    There's a common thought that gap years are only for rich students, but it's not true. Actually, taking a gap year can save your money. Gap year students often take a part-time job. Besides, at the end of a gap year, students are much more likely to know what to study in college. Clear learning goals ran keep the students working hard instead of wasting time and money playing.

    Imagine an admission officer trying to admit (录取) only one between two students. Both of them are excellent and have high grades. However, one student has much practical experience or has volunteered in his vacation. Who do you think the admission officer will choose?

    China has become the first country to successfully land a spacecraft on the far side of the moon. The Chang'e-4 probe (探测器) has also made the first lunar landing since 1972. It has the task of exploring the side of the moon that never faces the earth. The dark side of the moon is older and has a thicker surface than the visible side. It takes the moon as long to go around on its own axis (轴) as it does for one complete orbit around the Earth.

    The Chinese probe landed in a huge crater 2500 km in diameter and 13 km deep. The crater is one of the oldest parts of the moon and our solar system.

    Scientists hope to learn more about the geology of the far side of the moon. The craft has two cameras on board which will send images back to earth. It will also attempt to send signals to distant regions of space, something that cannot happen on earth because of too much radio noise.

    Chang'e-4 also has instruments on board to examine minerals as well as a container with seeds which will try to create a miniature (微型的) biosphere (生物圈).

Communication with the spacecraft is not easy. Images and other data must be transmitted to a separate satellite because no direct communication with the earth is possible.

    For China the Chang'e-4 mission is an important achievement, because the country has successfully done something no other nation on earth has. It wants to become a leading power in space exploration and has announced plans to send astronauts to the moon and set up its own space station.

An international team of astronomers used a database combining observations from the best telescopes in the world {#blank#}1{#/blank#} (detect) the signal from the active supermassive black holes of dying galaxies（星系） in the early universe. The {#blank#}2{#/blank#} (appear) of these active supermassive black holes is related to changes in the host galaxy. This means a black hole could have far reaching effects {#blank#}3{#/blank#} the evolution of its host galaxy.

The Milky Way Galaxy {#blank#}4{#/blank#} we live includes stars of various ages, including stars still forming. But in some other galaxies,{#blank#}5{#/blank#} (know) as elliptical（椭圆的） galaxies, all of the stars are old and about the same age. This indicates that early in {#blank#}6{#/blank#} (they) histories elliptical galaxies had a period of rich star formation that suddenly ended. Why this star formation stopped in some galaxies {#blank#}7{#/blank#} not others is not well understood. One possibility is that a supermassive black hole disrupts（瓦解） the gas in some galaxies,{#blank#}8{#/blank#} (create) an environment unsuitable for star formation.

To test this theory, astronomers look at distant galaxies. Due to the limited speed of light, it takes time for light to travel across the void of space. The light we saw last night from an object 10 billion light years away {#blank#}9{#/blank#} (travel) for 10 billion years to reach Earth. Thus the light we see today shows us what the galaxy looked like when the light left that galaxy 10 billion years ago. So looking at distant galaxies is like looking back in time. But the longer distance also means that distant galaxies look {#blank#}10{#/blank#} (small), making study more difficult.
