21、Women who own cats are more likely to have mental health problems and kill themselves because they can be infected by a common parasite(寄生虫) that can be caught from cat litter(猫砂), a study has found.
Researchers found women infected with the Toxoplasma gondii (T. gondii) parasite(刚地弓形虫), which is spread through contact with cat waste or eating undercooked meat or unwashed vegetables, are at increased risk of attempting suicide.
The study involved more than 45,000 women in Denmark. About a third of the world's population is infected with the parasite, which hides in cells in the brain and muscles, often without producing symptoms.
The infection, which is called toxoplasmosis(弓形虫病), has been linked to mental illness, such as schizophrenia(精神分裂症), and changes in behavior.
The study's senior author Doctor Teodor Postolache, an associate professor of psychiatry(精神病学) at the University of Maryland School of Medicine in the United States, said, "We can't say with certainty that T. gondii caused the women to try to kill themselves, but we did find a predictive association between the infection and suicide attempts later in life that deserves additional studies."
Doctor Albert Reece, vice president of medical affairs at the University of Maryland, said, "T. gondii infection is a major public health problem around the world, and many people don't realize they're infected. "
Dr Postolache is a leading expert on suicide neuroimmunology(神经免疫学). Suicide is a critically important mental health issue. About one million people commit suicide and another 10 million attempt suicide worldwide each year. We hope that this type of research will one day help us find ways to save many lives that now end too early in suicide."
Dr. Postolache's research team at the University of Maryland was the first to report a connection between T. gondii and suicidal behavior in 2009. He is cooperating with researchers in Denmark, Germany and Sweden to confirm and investigate the way leading to this association.
The T. gondii parasite thrives in the intestines(肠) of cats, and it is spread through their waste. All warm-blooded animals can become infected through contact with it. Humans can become infected by changing their infected cats' litter boxes, eating unwashed vegetables, drinking water from a polluted source, or by eating undercooked or raw meat.
Not washing kitchen knives after preparing raw meat before handling another food item also can lead to infection. Pregnant women can pass the parasite directly to their unborn babies and are advised not to change cat litter boxes to avoid possible infection.
Babies don't produce antibodies to T. gondii for three months after they are born, so the antibodies present in their blood represented infection in the mothers. The scientists studied Danish health patients to determine if any of these women later attempted suicide, including cases of violent suicide attempts which may have involved guns, sharp instruments and jumping from high places.
The study found that women infected with T. gondii were one and a half times more likely to attempt suicide compared to those who were not infected, and the risk seemed to rise with increasing levels of the T. gondii antibodies.
Dr Postolache noted limitations to the study, such as the inability to determine the cause of the suicidal behavior.
The findings were published online in the Archives of General Psychiatry.
【1】The common way which is less likely to be infected with the disease is ________.
A. to eat unwashed meat or undercooked vegetables
B. to clean a place where a cat once lived for a time

D. Becoming bad tempered.
【3】What can be inferred from the passage?
A. Women have a higher risk to be infected by the parasite than men.
B. The result of the research may help the scientists to find ways to stop suicide in advance.
C. The scientists will continue their research into the possible connection.
D. The risk of being infected seems to rise with the decreasing levels of the antibodies.
【4】Which of the following statements would probably be the best title of the passage?
A. Why are women more likely to commit suicide?
B. Women should keep away from cats
C. Ways found to deal with women's mental problems

22、Whether you are hoping to relax or you are looking forward to staying active in vacation, seeking out great hikes is a good choice. If you are planning a trip to southern California, or you live in San Diego, now it is time to search for new hiking trails (路线). Here are some of the most popular hikes in San Diego.
Cedar Greek Falls
For this hike, you’ll hike from the Cedar Creek Falls to the Devil’s Punch Bowl, which is a pool at the base of Cedar Greek Falls. It can really heat up in the summer, and it is hard to hike, so be sure to pack lots of water and protein-filled snacks.
Cuyamaca Peak (顶峰)
The peak is in Cuyamaca Rancho State Park, and you’ll see plenty of snow-capped trees if you do this hike in the winter. There are 37 trails in the state park, but you’ll want to stick to Azalea Glen Loop. It’s a difficult sever mile hike that will bring you right to Cuyamaca Peak.
Cowles Mountain
It is well known that Cowles Mountain is the highest point in San Diego—so it’s worth visiting for the fact that you can see Mexico from the peak. The three-mile hike is quite difficult. If you are willing to wake up before the sun, Cowles Mountain is a beautiful spot to watch the sunrise. It's one of San Diego’s most popular hikes, so starting early might also help avoid the crowds.
Swami’s Beach
Take the trail from Swami’s Beach to Cardiff Beach and you will experience impressive ocean views and the smooth sound of waves crashing onto the sand. As an easy out-and-back hike, the path is accessible (可进入的) from Swami’s Beach and is about three miles in total.

23、Thomas Mayfield had a major problem to solve in his fifth-grade classroom.
“I’m not good at adding. I don’t know how to regroup or borrow. I’m not good at subtracting (减法). Or I don’ t know my facts yet, and I’ m a fifth-grader, ” Mayfield’ s students used to tell him. The 42-year-old maths teacher from Fort Worth, Texas, knew it was important to try something new, especially because most of his students were also struggling outside of the classroom. “Single parent homes, parents put in prison, low financial stability-a lot of misfortunes that were going on, ” he said.
To reach students in a way that was familiar and inviting, he brought rap music to the classroom. Mayfield played an instrumental beat to a rap song. He got his students excited. Then they started to rap about decimal(十进位)point places. “Let’ s start with the tenths. Like a dime to a dollar, there’s 1 out of 10. Then we move to the hundredths, one part out of many. One out of 100, we call that a penny. . . “ rapped Mayfield and students.
Pareece Morehouse, one of Mayfield’s former students, is now in tenth grade and loves old-school rap. Before Mr. Mayfield’s class, Morehouse didn’t like maths and struggled with it. But pairing the difficult subject with music was game-changing for her.
“I can recall myself at home doing homework and just singing the song in my head, helping me understand, ” Morehouse said. “It was really a great way to help me make it through maths. ”
“Students will produce work if you reach them where they are and take notes on what they’re interested in, whether that’s music, art or sports. It’s important to use things that resonate (共鸣)with them, ” said Mayfield.
【1】What led Thomas Mayfield to try something new in his teaching?

24、Agatha Christie used to go out at night. She will never forget the night when she met a robber many years ago.
That evening, she was invited to a birthday party which lasted till 2 o'clock in the morning. Without company, Agatha walked home along the quiet street. Suddenly from the shadow of a dark building, a tall man with a sharp knife in his right hand ran out at her. “Good morning, lady,” the man said in a low voice, “I don't think you wish to die here!”“What do you want?” Agatha asked.
“Your earrings (耳环). Take them off!”Agatha suddenly had a bright idea. She tried to cover her necklace with the collar (衣领) of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground.

26、Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
Plan for Domino Effects on Sustainability Goals
Climate change is causing ever-more-extreme events, from storms and droughts to floods and violent windstorms, and these risks interact across many environmental and social systems. A heatwave can spark forest fires, which lead to air pollution. Drought-wrecked harvests can result in food-price unpredictability.
Yet these domino effects are barely considered in most countries’ strategies for achieving the United Nations Sustainable Development Goals (SDGs) by 2030. Many countries that are working hard to reach these goals insufficiently consider the impact of extreme weather. Take Germany as an example. Its 2018 strategy on sustainable development runs to 60 pages yet the word ‘disaster’ appears only once. There is no analysis of the consequences of an increase in such events.
Although many people are now aware that climate change is making fires, floods, heatwaves and storms more frequent, more severe or both, this knowledge isn’t changing policy or research enough. Part of the problem is perception. Future disasters feel unreal to decision-makers, as we’ve experienced with so many governments’ lack of pandemic preparedness, despite years of warning that something similar to COVID-19 was a case of when, not if. Other obstacles are inadequate national and international governance, and communication challenges. The research community has not yet provided effective guidance.
As a consequence, many efforts to achieve the SDGs will, like a house of cards, fall at the first shaking. Our global efforts need to be much more vigorous to the changing and interconnected nature of risk in a warming world.
What now? Researchers must create models that are more understandable and useful to policymakers. When possible, SDG targets and indicators should be redesigned to capture weakness to heatwaves, fires, droughts, floods, hurricanes, mudslides and more. And politicians need to be convinced to invest in precautionary measures and adaptation.
