Gender is just one factor when it comes to safe driving, along with others such as age, and even the time of day people drive. One study shows that both genders have a greater accident risk when driving at night, but males still have a higher risk at all times of the day. Driving quality also changes based on location, too, as some states are more dangerous than others. Data from the National Highway Traffic Safety Administration shows that Wyoming, Mississippi, and Montana have high accident death rates, without regards to gender. It goes to show that everyone should learn and practice safe driving habits instead of worrying about who drives better.

C. While driving in the daytime, male drivers have a greater accident risk than female drivers.

D. Many studies have shown that females are better and safer drivers than males.

26. What does the underlined word "variables" in Paragraph 4 possibly mean?

A. factors B. varieties C. phenomena D. consequences

27. From which column of a newspaper is the passage probably taken?

A. Science B. News C. Culture D. Traffic

Six months after a Chinese scientist was widely condemned for helping to make the world's first gene-edited babies, he remains out of public view, and new information suggests that others may be interested in undertaking the same kind of work outside the United States.

A clinic in the United Arab Emirates city of Dubai emailed scientist He Jiankui to seek training in gene editing, Stanford University bioethicist Dr. William Hurlbut said ahead of a speech Tuesday at the World Science Festival in New York.

Hurlbut, whose advice He often sought, said He told him that scientists from multiple countries and families with inherited health problems had messaged support and interest in altering the genes of embryos（胚胎）to prevent or treat disease. Hurlbut gave The Associated Press the email the Dubai clinic sent to He in December but decided to hide the clinic's name.

"It reveals what eagerness there is out there to use this technology" and the need "for some sort of practical governance" of it, Hurlbut said.

Jennifer Doudna, a University of California, Berkeley, co-inventor of the CRISPR gene-editing tool that He used, said that she also has heard of others who want to edit embryos.

"I think they're entirely credible," she said of such reports. Doudna, who was also a speaker at the New York festival, said the field needs to focus on setting specific principles for how and when such work should proceed.

"The technology is frankly just not ready for clinical use in human embryos," although research should continue, she said. Doudna is paid by the Howard Hughes Medical Institute, which also supports AP's Health and Science Department.

Scientists and policy leaders have been debating how to set international standards or controls since He claimed in November that he had altered the genes of twin girls at conception（怀孕）to try to help them resist possible future infection with the AIDS virus.

Editing embryos is outlawed in many countries because it risks damaging other genes, and the DNA changes can be passed to future generations. Many scientists have condemned He's work, and attention has fallen on other scientists who knew or strongly suspected what He was doing.

28. What is the email the Dubai clinic sent to He Jiankui probably about?

A. Expectation of gene editing training. B. Inherited health problems.

C. Eagerness to use the technology. D. Practical governance in need.

29. Why does Doudna think that there is need to put governance on gene-editing?

A. Because there is decreasing eagerness to use the technology of altering the genes of embryos.

B. Because the clinic use of the technology in human embryos is still in inadequate preparation.

C. Because the evidence showing people's need of the technology is just completely unbelievable.

D. Because some scientists or doctors may use the technology with the aim of making profits.

30. What can we infer from the passage?

A. He Jiankui used to held consultations with Hurlbut on gene editing.

B. It's still illegal to edit the genes of embryos in many countries.

C. How to set international standards or controls over gene-editing is still in heated debate.

D. Doudna assisted He Jiankui by providing a tool to alter the genes of twin girls at conception.

31. Which of the following can be the best title of this passage?

A. He Opens a New Age in Genetics

B. The First Gene-edited Babies in the World

C. A New Method of Preventing diseases

D. Gene-edited Babies Debate Continues
