1 . Teen Dating（青少年约会）can be fun if you are aware of its pros and cons(优缺点) and are also aware of the ways to protect yourself. There are a couple of suggestions you would like to know before you are out for dating.
Do not go out for dating with somebody whom you have seen only a few times and does not know much about him or her.
Before leaving on a date, know the exact plans for the evening and make sure a parent or friend knows these plans and what time to expect you home. Let your date know that you are expected to call or tell that person when you get in.
Similarly, if you leave a party with someone you do not know well, make sure you tell another person you are leaving and with whom. Ask a friend to call and make sure you arrive home safely.
No matter how good the person appears to you, trust your inner instincts (直感). If a situation makes you uncomfortable, try to stay calm and think of a way to remove yourself from the situation without letting your date realize what is going on in your mind.
Be aware of your decreased ability to react under the influence of alcohol or drugs and keep yourself in control when out for a date.
Always stay firm, straightforward and clear in your relationships, thoughts, decisions and judgments. Never let a doubt come to your mind or face when out for dating. If you are firm and clear in your communication, your date will always be careful in dealing with you.
You should think ahead about ways to be safe if you are in a dangerous or potentially dangerous relationship. Adults, like parents, teachers, counselors, can be trusted in such cases.

2 . The structure of DNA plays an important role in medicine and biology. But you may not know that its founder is a female scientist and goes through a lot on her way to make scientific research. Rosalind Franklin was born in London, England on July 25, 1920. On April 16, 1958, at age 38, she died from cancer. Franklin was responsible for much of the research and discovery work that led to the understanding of the structure of DNA.
Franklin was interested in science and attended one of the few girls' schools in London that taught physics and chemistry. When she was 15, she decided to become a scientist. Her father was decidedly against higher education for women and wanted her to be a social worker. Franklin's aunt decided to support her and she agreed to pay for her full schooling. Within weeks, Franklin's aunt got her mother to support her going to college also. Months later, Franklin's aunt and mother got her father to agree with it. Franklin was very excited that she was going to college and did a good job in her study.
After her graduation from college, Franklin started her research on DNA. However, there were so many quarrels in her life because Franklin and her research partner did not get along. Franklin and her partner's arguments set them back on the study of DNA quite a bit. At the time they were working against another pair to find the story of DNA. Because of Franklin and her partner's fights, another pair found the structure of DNA first and won the Nobel Prize for it four years after Franklin died. Many scientists felt sorry for her early death and thought that the winners had stolen her research about DNA.
1. We can learn from the text that Franklin ________.| A．died in her early thirties | B．was a really lucky scientist |
| C．didn't get along with her father | D．achieved a lot in the study of DNA |
| A．Franklin's father agreed to pay for her college education |
| B．Franklin's aunt loved her than others |
| C．it was not easy for Franklin to go to college |
| D．it has been Franklin's dream to be a scientist since she was a child |
| A．Franklin's scientific research was not easy |
| B．Franklin first found the structure of DNA |
| C．Franklin's partner had no interest in DNA |
| D．Franklin had enjoyed a peaceful life |
| A．How DNA Was Found? | B．DNA and Good Education |
| C．The Life of a Woman Scientist | D．Should Girls Study or Not? |
3 . American billionaire Elon Musk has demonstrated a technology designed to use a computer chip inside the head to control the brain. During a video demonstration on Friday, Musk provided details about the system, called Neuralink.
Musk says he hopes the technology can be used to treat neural disorders and help spinal injury victims regain body movement. Musk also believes the system could be used in the future to improve intelligence to help humans keep up with supercomputers and artificial intelligence (AI) technology.
During the show, Musk showed off a model of the Neuralink device. It is about 23 millimeters wide. It is designed to be implanted into a person's skull. Small wires would connect the device directly to the brain.
The Neuralink system is currently being tested in pigs, with plans to seek government approval for human testing sometime in the future.
A pig named Gertrude was also shown during the show. Musk explained that Gertrude had a Neuralink chip inside its head. The device is meant to record nerve activity in the pig's nose and mouth.
Musk said the company had three pigs, each with two chips. He described the animals as "healthy, happy and indistinguishable from a normal pig." Musk said the company was able to predict with "high accuracy" a pig's leg movement on a running machine using data from the chip.
Musk noted that Neuralink first wants to use the device on people with severe spinal cord injuries to help them talk and move using their brain waves. He said he is hopeful that, in the long term, those people could regain "full-body motion."
Some neuroscientists not linked to the company said the presentation suggested Neuralink had made great progress with the technology. However, they warned that many more studies will be needed to test the long-term success of such devices.
1. What good can the Neuralink device do to the disabled?| A．Making them think clearly. |
| B．Treating their diseases successfully. |
| C．Having them keep up with supercomputers. |
| D．Helping them to move again. |
| A．Normal. | B．Active. | C．Nervous. | D．Intelligent. |
| A．it has been a great success. |
| B．it will succeed very soon. |
| C．it has a long way to go. |
| D．It needs support from new theories. |
| A．There Will Be Great Progress in Brain Science. |
| B．Musk Shows Technology Linking Computer to Brain. |
| C．Three Pigs Are being Tested Instead of Human Beings. |
| D．The Disabled Will Receive Better Treatment in the future. |
