ChatGPT, an AI chatbot tool (聊天工具), has quickly become popular since it came out in late 2022. It can do a lot of things such as chatting, doing translations and even writing codes for a computer program. While it has surprised the world, it has also caused both excitement and worries in teaching and learning.

According to a survey covering over 1, 000 students and 100 educators, about 89% students said they used it to help with homework. About 48% said they used it to finish home tests. And over 50% used it to write an article. 34% of the educators said ChatGPT should not be banned (禁止) in schools and universities. But 66% thought students could not use it.

Now, some universities and schools in New York City have already banned the use of ChatGPT. They are really afraid that the tool could make it easier for students to cheat (欺骗) and be used to spread wrong information. Besides, they think the tool does not build creative-thinking and problem-solving skills, which are important for lifelong success.

However, some people think banning ChatGPT is not smart. Instead of simply banning it, using it can free teachers and students from the simple work so that they can do more creative work. To avoid (避免) cheating, instructions on how to use it in a right way should be given.

【小题1】ChatGPT is a ____________ AI chatbot tool today.
【小题2】According to the survey, over half of students use ChatGPT to __________________.
【小题3】In New York, some ________________ have stopped students from using ChatGPT.
【小题4】From paragraph 3 and 4, we know people have ___________ about stopping using ChatGPT.
【小题5】Do you want to use ChatGPT in your life? Why or why not?

The Internet nowadays opens a wide world to people, including teenagers, but many parents worry that their children may meet with something unhealthy when searching online. In order to solve this problem, a new search engine for children called Kiddle has appeared.

Search results are filtered (过滤), so only safe websites are shown and descriptions are written in simple language. Searches with bad words are shut off, too.

Kiddle uses the same colors as Google in its logo and a similar design on its homepage, too—with an extra robot picture.

The top three Kiddle search results show safe websites and pages written specially for kids, and those websites and pages are well chosen and checked by Kiddle developers.

The fourth to seventh results will be safe and trusted websites that are not written specially for kids, but have content written in a simple way. These results are also chosen and checked.

Results on the eighth and onwards pages are safe and famous websites that are written for adults. They provide expert content, but are harder for kids to understand.

Unlike on Google, most results appear along with large thumbnail pictures (缩略图) to make it easier for children to find what they are looking for. For example, when searching for “meow meow”. Google produces pages for information about a drug (毒品) that has “meow meow” as its nickname (绰号), but Kiddle lists information only about cats, even with some cat cartoon pictures.

The company explained, “Websites which appear in Kiddle search results satisfy family—friendly requirements, as we filter websites with unhealthy content.”

It’s important to teach children to create strong passwords(密码),and to remind them that passwords mustn’t be shared with anyone, not even best friends.
_______________________________________________________________.
It’s wise to use the whole keyboard to mix a password with letters, numbers and symbols.A password of 14 characters or more may be much safer.
The following tips will tell you how to create a strong and safe password:
Tip 1: Think of a sentence that is easy to remember, but difficult to guess.For example: “ My son Peter is five years old and my daughter Tina is one year old.” The whole sentence is so long that it can’t be a password, so what you can do is to use the first letter of each word to make a new password that seems to be meaningless.That is “mspifyoamdtioyo”.
Tip 2: Make the password more difficult to guess by mixing big and small letters.One way to do this is to use big and small letters one after another.In this way this new password will be “MsPiFyOaMdTiOyO”.
Tip 3: Still using the sentence above, you can also add numers that are meaningful to you.As a result, the new password will be “Mspi5yOaMdTi1yO”.
Tip 4: Add punctuation(标点符号)and symbols to make the password much stronger.You may use symbols, numbers and punctuation to replace some letters which look similar.For example: “MsPi3y0@MdTi!y0”.(o="0," a="@," 1=!)
