New rules and behavior standards (行为规范)for middle school students came out in March. Middle school is going to use a new way to decide who the top students are. The best students won’t only have high marks. They will also be kids who don’t dye (染) their hair, smoke or drink. The following are some of the new rules.

Tell the truth. Have you ever copied someone else’s work on an exam? Don’t do it again! That’s not something an honest student should do. If you have played computer games for two hours in your room, don’t tell your parents you have done homework.

Do more at school. Good students love animals and care for other people. April is Bird-loving Month in China. Is your school doing anything to celebrate? You should join! That way, you can learn more about animals and how to protect them. When more people work together, it makes it more fun for everyone.

Have you ever quarreled with your teammates when our basketball lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others, not only yourself.

Be open to new ideas. Have you ever thought that people could live on the moon? Maybe you’ll discover Earth Ⅱ someday. Don’t look down on new ideas. Everyone’s ideas are important. You should welcome them, because new ideas make life better for everyone.

Protect yourself. Has someone ever taken money from one of your classmates? Don’t let it happen to you. If you have to go home late you should let your parents know.

Use the Internet carefully. The Internet can be very useful for your studies. But some things on the Internet aren’t for kids, so try to look at Web pages that are good for you. You can use the Web for fun or homework. Can’t you find any good Web sites for children? Here some:http://kids.eastday.com/http://www.chinakids.net.com/http://www.cycnet.com

It wasn’t that long ago that TV advertising was the center of big companies with bigger budgets hoping to raise awareness and interest of their brands (品牌).

But the explosive (骤增的) growth of Connected TV (CTV) ruined the traditional model. Yes, major well-known names are still booming on television, but new brands of all backgrounds can unlock the benefits of TV, no matter their size or spend. That’s certainly a well-proven story. Still, one important question remains: Who are these brands that are redefining (重新定义) TV advertising?

The truth is just about every company can now be a TV advertiser. Brands were often locked out unless they unwillingly accepted late-night programs or struggling networks, well-known names hoping to measure standards that go beyond brand awareness, direct — to consumer (DTC) businesses with TV dreams and a digital advertising budget, or business — to business brands in need of changing.

So why are brands pouring to CTV? Because that’s where the audiences are. In fact, eMarketer estimates that 213.7 million viewers are watching CTV every month.

Ad dollars are following that viewership (观众人数): 41 of brands are rescheduling their social budgets toward CTV. And as the list of streaming platforms (直播平台) with or planning to include advertising grows (HB) Max, Hulu, Peacock, Disney+, and Netflix, more dollars are likely to follow.

But making the jump to CTV isn’t all about budget. Brands have been slow to do it due to a long lack of TV experience, concerns about responsibility, and an uncertainty around how to approach the enormous medium creatively and effectively.

There are still a lot of questions surrounding this new range of opportunity. So, let’s get up close and personal with three brands to understand why they’ve made the jump into CTV and finally, how they became successful CTV advertisers.

Professors at the University of California San Diego have developed microrobots, which can be a potential treatment for life-threatening cases of bacterial pneumonia, a serious disease affecting lungs and making breathing difficult. In mice, the microrobots safely removed pneumonia-causing bacteria in the lungs and resulted in 100% survival while untreated mice all died within three days after infection.

The microrobots are made of algae (藻类) cells whose surfaces are covered with substances that are filled with antibiotics (抗生素). The algae provides movement, which allows the microrobots to swim around and make antibiotics go directly to more bacteria in the lungs, helping absorb bacteria and clear them of infected cells. This give the microrobots the ability to reduce bacterial infection, which in turn makes them more effective at fighting lung infection.

The work is a joint effort by engineering professors Joseph and Zhang Liangfang. Together, they have pioneered the development of tiny drug-delivering robots that can be safely used in live animals to treat bacterial infections in the stomach and blood. Treating bacterial lung infection is the latest in their line of work.

“In the traditional treatment, sometimes only a very small number of antibiotics will get into the lungs. That’s why many current antibiotic treatments for pneumonia don’t work as well as needed,” said Victor Nizet, a co-worker of Joseph and Zhang “Based on these mouse data, we see that the microrobots could potentially improve the use of antibiotics to kill bacteria and save more patients’ lives.”

The work is still at the proof-of-concept stage. The team plans to do more basic research to understand exactly how the microrobots interact with the immune system (免疫系统). Next steps also include studies to confirm the effectiveness of the microrobot treatment before testing it in larger animals and eventually, in humans. “We’re pushing the boundary further in the field of targeted drug delivery,” said Zhang.
