Do you like to have any online classes? It is becoming 1 to take classes at home during the early 2020. All you need is a computer or a cellphone. However, most students don't seem to like online classes. A 2 shows that only 33% of over 1,500 students from 10 cities would take such classes.

Many students said it was difficult to focus(集中) on 3 while taking online classes. Lian Ruohan, 15, at the Affiliated High school of Peking University, said, "There are no real classmates sitting near me; no real teachers watching me. I can easily surf the Internet or do 4 things if I want to. It's harder to be always focused."

In order to avoid that, Lian will prepare a lot before classes to make sure she will learn 5 in class. She also pushes herself to communicate(沟通) with teachers about difficulties. She often 6 or answers questions while taking online classes.

Wen Jiayi, 14, at the Yucai Middle School, thinks online interaction(互动) isn't 7. "I have few chances to communicate with the online teachers, and they don't really get to know me. When I don't hand in homework, all I get is only a short telephone 8 instead of real care," she said.

However, Lian thinks online classes still have many 9. "It saves time and money compared to(和……相比较) taking official classes. Also, if I can't 10 some part of a lesson, I can watch it again to make it clear."

    Near the village, there is an old famous temple. Some people want to build a new house where the temple now stands, because they can find no other area to build them, while others disagree with them. They meet to decide how to solve the problem. Here are their opinions about it.

The expert wants to protect the temple and believes that there are some interesting things buried in the ground. If it is destroyed or moved, people may never learn about how people lived in the past.

The businessman thinks that the houses should be built. History is important, but we must think about the future. The village needs development and building new houses will offer jobs to hundreds of people.

Villager A says, "We should build the new houses because we need houses to live in."

Villager B says, "We should protect the temple because it can attract many tourists to come for a visit. If the temple is destroyed or moved, we will lose a lot of business."

The village leader thinks that he has a duty to make life better for the villagers. They need jobs and new houses. He also thinks the cultural site (遗迹) is important and they should be careful with it as well.

The Terracotta Warriors, one of the eight wonders of the world, have enjoyed international fame. Located in Xi'an in northwest China's Shaanxi Province, they are warriors of the first-ever emperor in1China or Qin Shi Huang in Chinese, Ying Zheng.

Even though I knew they are life-sized sculptures (雕塑), I was still2 when I saw them. I was lucky enough to3 the pit (深坑) and take a close look at them for the first time.

They were made around 2, 200 years ago. When I first got down into the pit, the sculptures scared me4some of them lacked body parts.

I was told that the Terracotta Warriors are not easy to preserve (保存;保护) for over thousands of years. But to my surprise, they were actually5 in color when they were first discovered. However, the color fell off6after being exposed in the air.

The difficulty of preservation is one of the reasons why they have stopped7out other pits. Although the Terracotta Warriors are breathtaking, they are only part of the Mausoleum (陵墓) of the First Qin Emperor.

Shen Wenxi, an expert and museum librarian of the Chinese Academy of Social Sciences, told me there's an even grander area8 man-made mountains, rivers and seas inside the emperor' s underground palace.

However, there is no plan to dig them until there are perfect9of protecting and preserving them. Experts are still busy restoring the relics (修复文物) that were10in the 1970s.

Gardening is a popular activity all around the world. But what about people who do not have the space to garden? Not to worry! Today, we will give you information about growing beautiful window boxes. 

Location and safety

Window boxes are not just for the outside edge of the window, they can also sit on other places such as, walls, porches, or front steps. This window box can be on the front steps to a home and the owners can entered their window boxes. 

But safety first: People do get killed by falling window boxes. Make sure your window boxes are safe so they will not come down in a storm. If you feel your window box could be unsafe, you can have an indoor window box.

Light and water

Before you choose plants, check your window box location for light and rain. Window boxes dry out faster than in-ground plants, so they need more water. And if a window box is close to a wall or other structure, it may not get enough rainwater. 

Even if all your windows get little sun, do not give up. You can get a great look using plants that love the shade. Many shade-loving plants like spiderworts and verbenas，have leaves in beautiful colors and interesting shapes. 

The "wow" factor

What gives some window boxes their "wow" factor while others are just so-so? Create a theme! This is a central idea for the plants. For example, you may have a window box that is all cactuses or all edible plants. Or you could select only purple violets or green basil, then you'll have a color-themed window box. 

Besides having a theme, upkeep is also important. You should cut off anything dead, water your window boxes often and change things a lot.
