5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Like most senior high school students in China, Liu Yu, had planned to continue her studies earlier this year to prepare for the upcoming College Entrance Examination.

However, the Ministry of Education (MOE) announced in late January that the spring term     1    (delay) due to the novel corona virus pneumonia(新冠肺炎) outbreak, forcing students     2    Liu to stay at home.

Instead of    3    (fall) behind their original plan, Liu and many others have already begun studying full--time again --- only from home,    4    may have become    5    largest online teaching trial(尝试) the country has ever seen. To go with students' new learning environment, a “cloud platform” was launched on Feb 17 to provide    6    (they) with education resources. For students in remote or rural areas, a television channel by China Education Television started airing    7    (class) on Feb 17 so they can study at home.

However, online teaching and learning has its weaknesses     8    (compare) to studying in a physical classroom. “My motivation(动力)to study is    9     (strong) when my classmates are around me and all working very hard,” Liu Yu said.

According to the MOE, online courses are only temporary measures taken during the epidemic(疫情). When the new term    10    (begin), schools will not replace classroom teaching with online classes.

6 . E-learning

Courses that are taught through the Internet，or online courses，have become popular in many countries.     1     But most show a video of a teacher and students in a classroom. Students watch the video online and take part in online activities. Some courses are free and open to anyone, giving students anywhere the chance to study at any time.

    2     Some schools in Singapore, for example, have tablets and touchscreens instead of books and blackboards in the classrooms. There are also social media platforms to help the students work together on projects, and online “worlds” where the students can interact with each other and the digital environment while completing different tasks.

    3     The teachers are in their home countries and are connected to the Korean classrooms through the Internet. Instead of looking at a screen, the students interact with a robot in the classroom. The robot is controlled by the teacher and can move around the classroom and talk with students. It is unlikely that robot teachers will replace real teachers.     4    

These important examples show us that e-learning can be successful. Thanks to technology, more and more ways of teaching and learning are being developed.     5    

However, one thing is for sure-there has never been a more interesting time to be a student.

A．There are different kinds of online courses.

B．Students are more likely to take part in a real class.

C．Other kinds of e-learning are being tested around the world.

D．Nobody knows what the classroom of the future will look like.

E．But like online learning environments, they can be useful tools.

F．In South Korea, some students are taught English by teachers abroad.

G．E-learning will surely replace the real classroom learning in the near future.

7 . Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.

As technology grows, many university instructors are finding ways to guide online learning platforms into their classrooms. Programs such as Blackboard, WebCT and Moodle allow teachers to post reading assignments, PowerPoint presentations, lecture notes and quizzes for students to complete outside of class. While posting lessons online can be friendly to students' communication styles and easily accessible, they also cause disadvantages.

One disadvantage is that it may encourage students to depend on technology in the classroom. Instead of physical textbooks, many now bring cellphones to access materials during class discussions. While electronic devices can be valuable learning tools, they also can lead to distractions from learning, such as social networking and online games. It is extremely difficult for students being exposed to multiple electronic tasks to focus or remember key information.

A second disadvantage is that online lessons open up potential for cheating. Many instructors require students to complete quizzes, post within discussion groups or submit major assignments online. As a result, there are some students having someone else complete their assignments. A contributing factor is that online assignments are best suitable for those self-motivated, self-directed students. Students who struggle with organization and completing assignments may find it easy to cheat online.

In spite of these disadvantages, educators can take steps to make sure students use online lessons responsibly. If instructors are uncomfortable with electronic devices in the classroom, they can require students to print out assignments and readings to reference during sessions. To prevent cheating, teachers can use online assignments as a supplement to traditional in-class work, or create open-ended assignments rather than using assignments like multiple-choice quizzes that have only one right answer. Being familiar with what the platform looks like from a student perspective also can help instructors avoid potential pitfalls.
