On Aug 27, 2020, Zhao Minghui, an associate professor at Qingdao Agricultural University’s College of Life Science, posted a “seeking marriage” notice online looking for a nine-month-old mate (配偶) for     1    (he) lab’s cat.

In the post, he described the cat     2    a volunteer of cell cloning technology, as well as an English speaker. As for the    3     (require) of the partner, the post said that healthy British long-haired cats who can speak with a London accent would be put on the top of the candidates list.

A research team, led by Zhao, cloned the cat for scientific study using a technique known as cell nuclear transfer. It is a special cat, the first one     4    (appear) at a domestic university cloning lab.

The clone, born on Dec 24,    5    (refer) to as Ping’an, meaning peace and safety. Over the past nine months, the cat     6     (grow) into the period of young adulthood    7     it is ready to mate. To today, three outstanding British long-haired cats have been selected. Zhao’s team    8     (accurate) get cat fertilized eggs at a special period of time by using the pre-established technology to collect early embryos (胚胎). The technology provides     9     important means to lay the theoretical basis for producing larger animal models of human diseases and studying the pathogenesis of diseases, thus     10    (promote) drug development.

2 . I’m Naomi Shah, and today I’ll be talking to you about my research involving indoor air quality and asthmatic（哮喘） patients. 1.6 million deaths worldwide. One death every 20 seconds. People spend over 90 percent of their lives indoors. And the economic burden of asthma go beyond that of HIV and tuberculosis（肺结核） combined.

Now these statistics had a huge impact on me. I started researching, and I soon found that indoor air pollutants were the main causes. But soon after, I developed a novel mathematical model that essentially measures the effect of these environmental pollutants（污染物） on the lung health of asthmatic patients.

I have a volunteer subject in the audience today, Julie. And all of Julie’s data has been pre-entered into my interactive software model. So Julie’s going to her doctor’s office to get treated for her asthma. And the doctor has her sit down, and he takes her peak breath flow rate. I’ve entered it up into the interactive software model. I’ve also entered in her age, her gender and her height. Any users just clicked on “lung function report” and it’ll take them to this report that I created. When the doctor sees this , maybe he would say, “Wow, we need to give her steroids（类固醇), medication and so on.”

But I want everyone here to reimagine a world where instead of prescribing steroids and medication, the doctor turns to Julie and says, “Why don’t you go home and clean out your air cleaner. Clean out the air dusts in your home, in your workplace, in your school. Stop the use of incense and candles. And if you’re remodeling your house, take out all the carpeting and put in hardwood flooring.” Because these solutions are natural, these solutions are sustainable, and these solutions are long-term investments -- long-term investments that we’re making for our generation and for future generations.

So I’m very passionate about this research and I really want to continue it and expand it to more diseases besides asthma, as well as more pollutants. To know more relationship between them is my main task. But before I end my talk today, I want to leave you with one saying. And that saying is that genetics loads the gun, but the environment pulls the trigger（扳机）.

3 . Can we “design” a baby like we design a handbag? It may sound crazy, but a “designer baby” could be possible now. Of course, at the same time, there are both agreements and disagreements with it.

The “designer baby” idea comes from the research that allows scientists to make changes to human DNA and genes. Usually, it is done when the baby is still just an embryo (胚胎). By doing that, scientists hope that “designer babies” will less possibly be born with some certain serious illnesses.

During the 21st century, the idea became so popular that the research developed very quickly. Now, it has been firstly used to help born babies with their illnesses. One example of this is that Dr. Adrian Thrasher of University College London was able to save a 1-year-old child from leukemia (白血病) with the help of it. People learned that it was not only illnesses they could change, but also a baby’s gender and looks. A well-known event happened in 1996. An American couple, Monique and Scott Collins, decided to use this research to help them choose the gender of their next baby. They wanted to have a baby girl for they have had three sons. Moreover, people could also decide babies’ eye color, hair color and even things like height or how sportive babies will be.

Some people argue that it is not ethical (道德的) to design babies like designing a bag. It is strongly against the nature’s rules. Besides, it may not have any bad influence on the baby now, yet no one knows what will happen to him and his children after many years.
