Research has become both simpler and more complex. It's simpler because, {#blank#}1{#/blank#} you have computer, you can find information you need by searching the Internet. For all you information, you don't have to go to {#blank#}2{#/blank#} library to find the relevant resource and take notes on it. Instead, you can find some sources from the Internet {#blank#}3{#/blank#} print the copies needed. Remember, however, that you should usually consult different types of sources. That is, you {#blank#}4{#/blank#} always rely just on the Internet for you research.

        While findinginformation is easier than ever, at the same time, researching has become {#blank#}5{#/blank#} complex. There is a lot more material available, which means you may be overwhelmed {#blank#}6{#/blank#} the amount of information. You need to learn {#blank#}7{#/blank#} to sort through and find the relevant information for your particular project. Also, {#blank#}8{#/blank#} need to check the accuracy of it.

    Good evening, everyone! It is my honor to be here to share something with you. Today my topic is “Stop {#blank#}1{#/blank#}(choose) merit students(优秀生)”.

    There is no doubt {#blank#}2{#/blank#} choosing merit students may inspire some students to learn from those models, which make many parents happy, for they always attach great importance to their education. However, this way has its {#blank#}3{#/blank#} (weak). As we know, the students are still young, and choosing merit students may be {#blank#}4{#/blank#}(harm) to their mental health by sorting them into good students and bad students. So it {#blank#}5{#/blank#}(obvious) doesn't benefit them in health. At the same time, teachers are always {#blank#}6{#/blank#}(drown) in teaching, thus ignoring their virtue and PE, which does more harm {#blank#}7{#/blank#} good to the growth of students.

As a matter of fact, what is more important is that we should take measures to enter their minds to find {#blank#}8{#/blank#} they are thinking and desiring. Only in this way can we really find an effective method {#blank#}9{#/blank#}(guide) them at school. Everyone may have a balanced {#blank#}10{#/blank#}(develop).

    That's all.

    Thank you for listening!

    The Great Wall of China is more than 6,000 kilometres long. It winds {#blank#}1{#/blank#} (it) way from west to east, across deserts, over mountains, through valleys{#blank#}2{#/blank#}at last it reaches the sea. The Great Wall has a history of over twenty centuries. The first part of it {#blank#}3{#/blank#}(build) during the Spring and Autumn period. During the Qin Dynasty, {#blank#}4{#/blank#}(keep) the enemy out of his empire, Emperor Qin Shi Huang had all the walls {#blank#}5{#/blank#}(join) up. Thus, the Great Wall came into being. The Great Wall is wide enough at {#blank#}6{#/blank#}top for five horses or ten men to walk side by side. Along the wall are watchtowers, {#blank#}7{#/blank#}soldiers used to keep watch. Fires were lit on the towers as a {#blank#}8{#/blank#} (warn) when the enemy came.

    It was {#blank#}9{#/blank#}(extreme)difficult to build such a wall in the ancient days without any modern machines. All the work was done {#blank#}10{#/blank#}hand. Thousands of men died and were buried under the wall they built. The Great Wall was made not only of stone and earth, but of the flesh and blood of millions of men.

    The Moon's near side, the one we all see, has been the target of many robotic and human missions. However, its far side, also {#blank#}1{#/blank#} (call)the dark side because it faces away from the Earth and little {#blank#}2{#/blank#} (know)about it, has never been explored. That changed on Jan.2, 2019, when Chinese spacecraft Chang'e 4 made a soft landing on {#blank#}3{#/blank#} is often referred to as the dark side.

    The landing is {#blank#}4{#/blank#} example of China's growing desire {#blank#}5{#/blank#} (compete)with the American, Russian and European space programs. China also wants to {#blank#}6{#/blank#} (strength)its position as a regional and international power.

    One of the great {#blank#}7{#/blank#} (difficulty)in exploring the far side of the Moon is that it blocks all radio signals, {#blank#}8{#/blank#} (make)it impossible to communicate with the Earth. To overcome this difficulty, in 2017, the Chinese National Space Administration launched a satellite to orbit the Moon and relay the signals. Once a {#blank#}9{#/blank#} (rely)communication path was in place, Chang'e 4 could send back information.

    Chang'e 4 will make astronomical observations and examine the structure and mineral composition of the ground above and below the surface, {#blank#}10{#/blank#} researchers believe will provide insights into the solar system's early days and perhaps even the origin of the first stars.

    When Robert Lee was in primary school, he hated to see his classmates throwing away half-eaten sandwiches after lunch. His parents had taught him and his older brother not to waste food. “They said it was bad,” says Robert, 27.

    While {#blank#}1{#/blank#} (study) finance and accounting at New York University, Robert remembered this lesson and joined Two Birds One Stone, a food rescue club at school {#blank#}2{#/blank#}delivered, five days a week, uneaten pasta, vegetables and other leftovers (剩余食物) from the dining hall to nearby homeless {#blank#}3{#/blank#} (shelter).

    When Robert and fellow club member Louisa Chen entered a college {#blank#}4{#/blank#} (compete), they came up with a slightly different idea for a food rescue non-profit group—{#blank#}5{#/blank#} (it) program wouldn't have a donation minimum, would operate seven days a week, and would be staffed {#blank#}6{#/blank#} (entire) by volunteers.

    Surprisingly, {#blank#}7{#/blank#} idea stood out. Robert and Louisa Chen won the first place. {#blank#}8{#/blank#} the $1,000 prize, they founded Rescuing Leftover Cuisine (RLC) in July 2013. In just the first few weeks, Robert steam delivered a donation of enough noodles and meatballs to feed 20 people in line at a New York City homeless shelter that had run out of food. Only a year into his finance job, Robert gave up his six- figure salary {#blank#}9{#/blank#} (focus) on RLC. So far the organization {#blank#}10{#/blank#} (reach) sixteen cities around the country.
