An exciting landing process of Chang'e-4 lunar probe (月球探测器)was seen through the monitor at Beijing Aerospace Control Center in Beijing,Jan. 3, 2019. It touched down on the far side of the moon at 10:26 a.m. Beijing Time, becoming the first spacecraft soft-landing on the moon’s unknown side never visible from Earth.
China’s Chang'e-4 probe has started the exploration on the far side of the moon thanks to the relay satellite that provides a communication link with ground control. The relay satellite, named Queqiao, meaning Magpie Bridge, after a Chinese legend, was launched on May 21,2018,and became the first communication satellite operating in the halo orbit, nearly 500,000 km from the earth. It can also provide communication for probes from other countries. The relay satellite will also be used for scientific and technological experiments. The maximum distance between the satellite and the Chang'e-4 probe on the far side of the moon is 79,000 km. The satellite processes data from the probe and sends it to Earth.
The satellite can stay in its orbit for a long time due to its relatively low fuel consumption, as the earth’s and moon's gravity balances its orbital moving. While in orbit, it can “see” both the earth and the far side of the moon.
The concept of using a relay satellite in the halo orbit was first put forward by U.S. space experts

C. Researchers. D. Managers.
in the 1960s, but was realized by Chinese space engineers.
Researchers hope to use the cameras on the satellite to record asteroids (小行星)hitting the far side of the moon. To control the cost of the Chang'c-4 probe, the relay satellite was designed to be relatively small, weighing about 400 kg.
Researchers had just 30 months to develop the satellite, putting them under high pressure. To promote public interest in space exploration, the China National Space Administration invited people to write down their wishes for lunar and space exploration, and the relay satellite carries the names of tens of thousands of participants and their messages. 44. What do we learn from the second paragraph? A. The relay satellite was launched on Jan. 3, 2019. B.Chang'e-4 probe was the first communication satellite. C. The relay satellite only explores the far side of the moon. D. The relay satellite can handle data from Chang'e-4 probe. 45. Why was the size of the relay satellite relatively small? A. To reduce the cost as much as possible. B. To make it circle Moon for a longer time. C. To avoid being crashed by other satellites. D. To follow American space experts,advice. 46. What made researchers suffer from great stress? A. Few people interested in the exploration on the moon. B. The relay satellite carrying too much equipment. C. Their lacking enough time to develop the relay satellite. D. People’s never being optimistic about the relay satellite 47. What is the main idea of the text? A. China is a new space power after the USA. B.Change-4 probe lands on Moon’s far side. C. Chinese space engineers make much progress. D. Space exploration is a dangerous challenge. Passage D
Last year marked the 100th anniversary of the end of World War I. There were events around the
7
world in memory of those who died in the conflict. We have picked out three of them in European countries. Let's take a look. Belgium
In a park, the famous Belgian artist Koen Vanmechelen had an exhibition called Coming World, Remember Me. The work consisted of 600,000 individual(单独的)clay sculptures, one for exhibition was a big egg made of clay each person killed during the World War. In the center of the exhibition was a big egg made of clay, symbolizing a new world. UK
In a small town called Aldridge. almost 100 houses in one street were covered with 24,000poppies and statues of sold.
They stood for the men from the area who had been killed in the war. The flowers were chosen because of a poem written by the Canadian doctor John McCrea in1915. They made people think of fields of blood. France
The British artist Guy Denning arrived in La Feuille,a small town in the northwest of France, to stick life-size drawings of soldiers who never came back home. Armed with glue and a brush, Denning stuck his drawings carefully on walls. Before long 112 men, ma.nly young adults, were brought back to mind, if not to life.
48. What do we know about Coming World. Remember Me? A. It's the name of an exhibition. B. It's a film about World War I. C. It's a work standing for peace. D. It's a sculpture made of clay.
49. Why were poppies chosen to symbolize the dead soldiers? A. The British people preferred them. B. They showed the cruelty of war. C. A Canadian doctor suggested them. D. The fields were filled with them.
50. How was the end of World War I marked in France? A. A memorial to the dead soldiers was built.

Technology in education: Current trends
A) Computers and Internet connections are becoming widely available in schools and classrooms. In 1999, 99 percent of teachers in the United States had access to a computer in their schools, and 84 percent had one or more computers in their classrooms. At the same time, Internet connections were also widespread, with 95 percent of schools and 63 percent of classrooms having access. Worldwide, many countries are making the creation and diffusion of information and communications technology (ICT) an important priority. The use of technology to find educational resources
B) In the past, teachers attempting a problem-based curriculum felt the need to limit problems to those for which they had expertise or the local library had resources. Now the World Wide Web brings a seemingly endless amount of information on almost any subject, and it is possible for students to choose topics based on personal interest rather than availability of resources. C) Internet research projects are gaining popularity. In the spring of 1998, 30 percent of teachers surveyed (and 70 percent of those with high-speed Internet connections) reported they had assigned Internet research tasks to their students during the school year. Use of the Internet to gather information for solving problems sometimes resembles a modern version of library research, in which students gather and synthesize information from published reports. Despite the fact that the task seems traditional, the characteristics of this new medium require special skills for students. The sheer volume of information allows students to study almost any topic, but also makes it more difficult to locate precisely the right information from among the thousands, or even millions, of sites. In addition, the ease of publishing materials on the Internet increases the likelihood that students will encounter inaccurate or biased information. As a result, students must learn new strategies for conducting searches and evaluating the information that
9
they retrieve.
D) Students carrying out scientific investigations can use the Internet to make observations and collect data. For example, the fourth and fifth graders in California collected insects and sent them to San Diego State University. Using two-way audio and video connecting the school and the university, scientists guided the students in using an electron microscope to examine their specimens. Technology has made it possible to collect data from places students could never visit. In recent projects, high school students explored the floor of the Monterey Bay by studying the video from remotely operated robots, and middle school students were given time to use the Hubble telescope. Students also use technology to collect data in their schools and communities. For example, using handheld computers outfitted with various types of probes (探测仪), students can monitor the water quality at various locations in nearby streams or lakes. By transmitting their individual readings to a laptop computer in a field laboratory they can quickly graph their data and visually compare readings. The use of technology to summarize and present findings
E) In the past, students memorized and used formulas and models created by others to solve problems. Students often used these formulas, especially in the early stages of learning, with little understanding. In the early 21st century computer tools provide the opportunity for students to construct and test their own models using tools such as spreadsheets (电子制表软件) or concept maps (概念图). This type of instruction deepens students' understanding of abstract concepts and allows these concepts to be taught at an earlier age.
F) Once students have summarized their data and other information, they typically communicate their findings to others. Writing reports is still the most widespread use of ICT, with 61 percent of US teachers assigning students word-processing tasks. In addition to text, students also use computer-created graphics, videos, and animations to communicate their ideas.
G) The teacher is not the only audience for students' presentations. Students frequently expect to present their work to and receive feedback from their peers and the world outside their classroom. Whether they are using presentation software to accompany a face-to也ce
