Nowadays WeChat is more and more popular. I often talk to my English friends on WeChat, which helps me speak English     1    (well) than before. And I can read lots of news on WeChat that can make me     2    (find) out what's going on around my daily life. Some news also makes me become more careful. Sometimes I feel WeChat is like     3     mirror that helps me see something     4    (clear).

But now, WeChat brings me some trouble,     5    . Some friends put photos of the real things on WeChat to tell what they sell is really good. I'm angry about these advertisements(广告),     6     some of them may not be true. Just as the saying     7    (go), “Seeing is believing.” I know some people are cheated(欺骗) by some news easily. Even some news always asks us     8    (send) it to others. This makes     9    (I) uncomfortable.

In fact, I'm thinking about never using     WeChat on my phone again, because using it   too much is bad    10     my eyes.

Recently Google has announced a series of new artificial intelligence (AI) (人工智能) tools designed to help users in organizing emails and creating business writings and meetings. These tools display important AI development progress in recent years. The tools are built by putting a great d    1     of data (数据) into machine learning computer systems. The data trains the AI systems to develop skills and produce human-like results.

The technology received w    2     attention last year after a company called Open AI announced a free writing tool called Chat GPT. That tool can quickly produce human-quality writings. Experts (专家) say s    3     systems may bring great changes to many different industries and jobs. Now some companies are a    4     to test Google’s new tools in their development and business activities.

Like Chat GPT, Google’s AI tools are designed to create completely written texts f    5     many different purposes. For example, an office worker could enter some keywords of a kind of text they want. The tools could then create a full marketing email, training materials or a business plan in a while. Google sees the system being able to o    6     an “AI Helper” to help human workers in real time. Google wants to have its AI change the work of lawyers, scientists, teachers and more.

However, Google says it keeps developing AI products of high quality. That is why the company is inviting groups of “trusted testers” to use its AI tools r    7     than widely selling its new products. Google’s new AI tools are the company’s l    8     move to fight for business. Companies l    9     Microsoft and Meta are also working on products about AI.

Technology experts have w    10     that while the new AI tools can produce human-like writings, the systems can also make mistakes. Last month, Bard, Google’s new AI tool designed to give a better online search, made a mistake and caused a $100-billion drop. Microsoft users said the company’s new AI tools produced unfriendly and rude results.
