It was sunny last Saturday. Mr. Black {#blank#}1{#/blank#} his children to the zoo. When they {#blank#}2{#/blank#} there, they saw many people and animals.

The children went to the lake first. There they saw many fish {#blank#}3{#/blank#} in it. Jane was really happy, "Look, how beautiful the fish are! I hope I can swim {#blank#}4{#/blank#} them." Then they went to the bird garden. There were different {#blank#}5{#/blank#} of birds in it. These birds were not {#blank#}6{#/blank#} when people were near them. Mr. Black bought some bird food for the children {#blank#}7{#/blank#} them. The children were very happy. After {#blank#}8{#/blank#} many hours in the zoo, the children were hungry. Then Mr. Smith took them to a {#blank#}9{#/blank#} for lunch. The food was expensive {#blank#}10{#/blank#} very delicious. All in all, they had a great day.

It's early in the morning and the alarm clock has already rung several time. You have to pull yourself out of bed and rush to school because you're afraid of being late for school.

As a school student, this is probably a common experience for you. But thanks to new rules, students in Zhejiang and Heilongjiang provinces can now stay in bed longer than before.

On Feb 23, the Zhejiang Department of Education announced (宣布) a new rule that asks primary schools to start school later. According to the rule, start times could be different among different grades, with students in Grade 1 and 2 starting no earlier than 8:30 am.

A similar guideline (指导方针) was announced by the education department in Heilongjiang Province on Feb 24. Students from all primary and junior high schools in the province have been required (要求) to arrive at school no earlier than 8 am.

According to a 2016 study by the Zhejiang Department of Education, half students in Grade 4 slept nine hours or more a night, while the enough sleep time for primary students in 10 hours.

"I welcome the new rule so much. It is such a wonderful rule that gives my son enough time for breakfast, which is necessary for his health and growth", a mother named Xu Li said. She is from Hangzhou and his son is in Grade 1. These changes have received much praise as they make students get enough sleep and enough time for breakfast.

Pushing back school times isn't unique (唯一的) to China. In the United States, schools in at least 21 states began to start school later in 2017, as studies have shown that later school start times could be good for students' development.

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."

Computers make people's lives really easy. People can use their computers for working, {#blank#}1{#/blank#} (shop), or playing games. Laptop (笔记本) computers make people's lives even {#blank#}2{#/blank#} (easy) as people can take laptops anywhere. They can work, shop, or play games any place {#blank#}3{#/blank#} any time. {#blank#}4{#/blank#} there is a problem with laptops. People can {#blank#}5{#/blank#} (burn) by them!

People who sit with laptops on {#blank#}6{#/blank#} (they) legs for hours and hours have noticed they get dark marks on their legs. The hot laptop is toasting the skin. {#blank#}7{#/blank#} (doctor) have noticed more people show up with "toasted skin syndrome (综合症)". The marks are not {#blank#}8{#/blank#} (danger), but they look strange because they are just in one spot on people's legs.

Companies that make computers tell people not {#blank#}9{#/blank#} (let) warm computers touch bare skin for a long time. Wearing pants and putting a laptop's case under the laptop is {#blank#}10{#/blank#} (usual) enough to protect one's skin from the computer's heat.
