Nowadays, advertisements can be seen everywhere. They have made a really bad  I{#blank#}1{#/blank#}on people for various reasons. First of all, their constant  {#blank#}2{#/blank#}(出现)on different media disturbs people's normal life. Besides, the skillful methods are used so {#blank#}3{#/blank#}(频繁地)to cheat consumers that they have great difficulty d{#blank#}4{#/blank#}useful information from lies. However, despite the s{#blank#}5{#/blank#}mentioned above, advertisements do play an important role in our daily life. With different products being developed everyday, advertisements make it more {#blank#}6{#/blank#}(方便的）for consumers to get necessary information and make comparisons, thus purchasing the best goods. What's more, public service advertisements, or PSAs, provide people with e{#blank#}7{#/blank#}about health, safety, or any other problem that affects public welfare. By dealing with widespread s{#blank#}8{#/blank#}concerns, they lead us better lives. {#blank#}9{#/blank#}(因此), instead of blaming advertisements all the time, we have to admit that they are indeed b{#blank#}10{#/blank#}to each person as well as the society.

    We think that life in Chinese high school is an adventure in which we have to survive mountains of homework and all kinds of exams. Yet would it be{#blank#}1{#/blank#}(surprise) if I tell you that high school life in the US is almost as stressful and demanding as it is in China?

    In US high school, everything{#blank#}2{#/blank#}(record) into your studying document, including your grades on quizzes, tests and final examinations. Failing{#blank#}3{#/blank#}(turn) in your homework on time will directly affect your grade for a certain course. Perhaps contrary to{#blank#}4{#/blank#}we used to think of the US high school students, they pay more attention to their{#blank#}5{#/blank#}(academy) performance to try to get into a distinguished university.{#blank#}6{#/blank#}, they'll be disappointed after graduation from high school.

    Like university students, US high school students have the{#blank#}7{#/blank#}(free) to choose the courses that most interest{#blank#}8{#/blank#}(they). Even a ninth grader can sit{#blank#}9{#/blank#}the same classroom as twelfth graders. But this also means he or she has to work very hard, because the teacher will not treat him or her differently just because he or she is a few years{#blank#}10{#/blank#}(young).

    A Frenchman went to a small Italian town {#blank#}1{#/blank#} stayed with his wife at the best hotel there. One night, he went out for{#blank#}2{#/blank#}walk alone. It was late and the small street was dark and{#blank#}3{#/blank#}(quietly). Suddenly he felt someone behind him. He turned his head and saw an Italian young man {#blank#}4{#/blank#}walked past him quickly. The man was nearly out of sight when the Frenchman suddenly found that his watch was {#blank#}5{#/blank#}(go). He thought that it must be the Italian who had taken his watch. He decided {#blank#}6{#/blank#}(follow) him and get back the watch. Soon the Frenchman caught up with the Italian. Neither {#blank#}7{#/blank#}  them understood the other's language. The Frenchman frightened the Italian with his fist(拳头) while {#blank#}8{#/blank#} (point) at the Italian's watch. In the end, the Italian gave his watch to the Frenchman. When he returned to the hotel, the Frenchman told his wife what had happened. He was {#blank#}9{#/blank#} (great) surprised when his wife pointed to the watch on the table. Then he{#blank#}10{#/blank#}  (realize) that by mistake he had robbed the watch and it was the Italian's.

    When foreigners negotiate, or register in certain areas of China, they may be {#blank#}1{#/blank#}(surprise) at Chinese's special fondness and preference for seals. To Chinese, seals are an art of deep cultural roots, {#blank#}2{#/blank#} combines the essence of both calligraphy(书法) and sculpture and inspires generations to study, to appreciate and to collect.

    It is believed that seals came out as early {#blank#}3{#/blank#} 8,000 years ago after our ancestors could make pottery wares(陶瓷)and had private property. They were assumed to make marks on {#blank#}4{#/blank#}(they) own possessions to prevent them from being stolen. When the first dynasty {#blank#}5{#/blank#}(found),the king began to use seals to empower(授权)and to show lordly credits. Only the king's special seal was then called "Xi", {#blank#}6{#/blank#}(represent) the highest authority. The first emperor of China, Qin Shi Huang, had his "Xi"{#blank#}7{#/blank#}(make) out of the invaluable and beautiful jade "Heshi Bi".

    Then the local governments also needed seals for {#blank#}8{#/blank#} same function. Meanwhile, private seals were carved in a variety of lucky {#blank#}9{#/blank#}(character)and vivid animal patterns.{#blank#}10{#/blank#}(gradual). the sphragistics (印章学) came into being.

    It's difficult to say exactly when IWD(International Women's Day) began. It dates back to 1908, {#blank#}1{#/blank#} 15,000 women marched through New York City demanding voting rights, better pay and {#blank#}2{#/blank#}(short) working hours.

    A year later, the first National Woman's Day {#blank#}3{#/blank#}(allow) in the US on February 28, according to an announcement by the Socialist Party of America.

    In 1910, a woman {#blank#}4{#/blank#}(call) Clara Zetkin—leader of the "women's office" for the Social Democratic Party in Germany came up with the idea of International Women's Day. She suggested that every country {#blank#}5{#/blank#} (celebrate) International Women's Day on one day every year to push for their demands.

    A meeting of more than 100 women from 17 {#blank#}6{#/blank#}(country) agreed to her suggestion and IWD was formed. In 1911, it was celebrated for {#blank#}7{#/blank#} first time in Austria, Denmark, Germany and Switzerland {#blank#}8{#/blank#} March 19.

    In 1913, it was decided {#blank#}9{#/blank#}(change) IWD to March 8, and it has been celebrated on that day ever since. The day was only recognized by the United Nations in 1975. It {#blank#}10{#/blank#}(create) a theme (主题) each year for the celebration ever since.

After traveling through space for seven months, China's Tianwen-1 probe has reached Mars and {#blank#}1{#/blank#}(success) entered its orbit on Wednesday — bringing it one step {#blank#}2{#/blank#} (close) to landing on the surface.

Tianwen-1, {#blank#}3{#/blank#}name means "Quest for Heavenly Truth", consists of an orbiter, lander and a six-wheeled rover. The spacecraft {#blank#}4{#/blank#} (launch) last July along with two other international Mars missions, is scheduled to land on the planet's surface in May or June. It is tasked with gathering information about Mars' geological structure, atmosphere, environment and soil, as well as {#blank#}5{#/blank#} (search) for signs of water.

With Tianwen-1, China is the first nation {#blank#}6{#/blank#} (attempt) to send both an orbiter and a rover on its first homegrown Mars mission. {#blank#}7{#/blank#} contrast, NASA sent multiple orbiters to Mars before ever attempting a landing, since pulling off the landing is {#blank#}8{#/blank#}far more difficult task.

The Chinese rover {#blank#}9{#/blank#}(expect) to function for about three months on the planet. It marks a milestone for China's deep-space {#blank#}10{#/blank#} (explore) of Mars, according to the CNSA. China is also planning to launch a permanent space station by 2022, and is looking at sending astronauts to the moon-possibly in the 2030s.
