1 . Having lived in California until 1970, my family has felt a number of earthquakes. We have been fortunate, however, to have suffered no bodily harm or property damage.
There is a website that lists all California earthquakes recorded from 1769 to the present. The site lists the dates and times as well as the magnitude(震级) and the exact location of any quake that measured more than 6.0.
There are only a few quakes that stand out in my memory and, luckily, none is shown in the website. So, my personal experience with earthquakes might be considered insignificant.
There are three earthquakes that are difficult to forget. The first one was in 1955 and our oldest daughter was walking with me in our backyard in Redwood City in California. As the shaking became stronger I held her to me with one arm as I held on to one of our fruit trees with the other. All three of us (my daughter, I and the tree) shook for two or three minutes that to us felt like hours.
The second one was in 1963.Our entire family was visiting Disneyland in Southern California. The earth started to shake just as we were beginning to walk from our hotel toward the famous landmark.
My third experience with an earthquake was a lonely one in California. It was in my sixties and I was alone in an old church.As the building started to shake, I quickly headed for the door to go outside. I remember I said a little prayer—something like, “Help me get out of here in time, Dear Heavenly Father”. Minutes later, I was safe outside.

2 . With low or no-carbohydrate diets rising in popularity in recent times, the potato is now regularly overlooked in favour of other vegetables. In fact, research literature has previously indicated potatoes may have a detrimental effect on health, such as increasing the possibility of developing Type2 diabetes(糖尿病).
However, new research done by Edith Cowan University (ECU) has shown while potatoes may not have all the same benefits as some other vegetables, such as lowering risk of Type 2 diabetes, health issues associated with potatoes may actually be due to how people are preparing them and what they’re eating them with.
A recent analysis of this study led by Dr Nicola Bondonno from ECU’s Nutrition and Health Innovation Research Institute found people who consumed the most vegetables were 21 percent less likely to develop Type 2 diabetes than those who consumed the least amount of vegetables. PhD candidate Pratik Pokharel carried out work on the analysis and said while potatoes didn’t have the same impact on Type 2 diabetes, they also didn’t have any negative effect.
“In Denmark, people consume potatoes prepared in many different ways. In our study, we could distinguish between the different preparation methods. When we separated boiled potatoes from mashed potatoes(土豆泥), fries or crisps, boiled potatoes were no longer associated with a higher risk of diabetes: They had a zero effect,” said Pokharel.
“In our study, people who ate the most potatoes also consumed more butter, red meat and soft drinks-foods known to increase your risk of Type 2 diabetes,” said Pokharel. “We should separate potatoes from other vegetables in regard to messaging about disease prevention but replacing refined grains such as white rice and pasta(意大利面食)with potatoes can improve your diet quality because of fibre and other nutrients found in potatoes.”

3 . Here are some fantastic parks in San Antonio.
Brackenridge Park
The park was first established in 1899 and has been popular with both locals and visitors ever since. Towering trees and peaceful riverbanks will greet guests along the park’s paths, and the facilities include playgrounds, museums, a miniature train, a Japanese tea garden, and one of the oldest golf courses in the city.
Friedrich Wilderness Park
In the park, you’ll find about 10 miles of paved(铺过的)and unpaved trails(路线), with a little something for everyone. From rocky climbs to deep canyons, and enchanting forests to open views, there’s no shortage of natural beauty. The area is nationally famous for birdwatching.
San Antonio Missions National Historical Park
The park is the state’s only one on the list of UNESCO World Heritage Site. It covers quite a large area, so it’s best to make it a full-day or at least a half-day trip so you can be sure to cover everything. While the Alamo is a separate attraction, you will get to enjoy the architectural wonders of Mission Concepcion, Mission San Jose, Mission San Juan, and Mission Espada. They’re all connected by a hike and bike trail, with plenty of stops along the way to picnic, climb trees, and refill water. Admission is free!
Eisenhower Park
Just a 20-to 30-minute drive from the city center, the park puts the best landscapes in the Texas Hill Country on full display, holding 6 miles of hiking trails, both paved and unpaved. Explore dried creek beds, look out over plunging canyons, and enjoy full views of San Antonio down below. You can also find playgrounds for the little ones, picnic tables, and barbecue facilities.

4 . Spending time outdoors has long been linked (联系) to better health. Gardening goes beyond just beautifying outdoor spaces—it can have a deep effect on our physical and mental (身心上的) health.
Gardening involves physical activity that works all the main muscle (肌肉) groups, which is helpful for overall health. “Activities such as digging, planting, weeding and harvesting require movement and can help to improve strength,” said Clayton, CEO of an online lawn care company. “Performing these activities regularly can help burn calories, and keep a healthy weight.”
Beyond burning calories and building muscle, lots of studies have shown that gardening can improve the immune system (免疫系统). The Centers for Disease Control and Prevention (CDC) recommends that people get at least 150 minutes of exercise each week, and gardening is listed as a suitable activity. Doing garden work for that time each week can reduce the risk of obesity, high blood pressure and heart disease. Additionally, spending time outdoors makes us get close to natural sunlight, which is important for vitamin D synth.
Gardening provides a chance for social connection, too. It can be a shared activity among family members, friends or neighbors, building relationships and a sense of belonging.
Gardening also offers cognitive (认知的) benefits. It excites the senses, improves focus and encourages problem-solving and creativity. It provides a chance to learn about plants, ecosystems and the environment, developing a deeper understanding and appreciation for nature.
1. What is Clayton’s attitude towards gardening?| A．Supportive. | B．Doubtful. | C．Unclear | D．Uncaring. |
| A．It improves focus. | B．It is a waste of time. |
| C．It can keep a body in shape. | D．It helps to reduce the risk of diseases. |
| A．It contributes to creativity. | B．It encourages problem-solving. |
| C．It builds relationships between people. | D．It improves people’s awareness of safety. |

5 . There’s no doubt that football is the global sport. Though basketball, tennis, and other sports are popular too, nothing comes close to football. Being played in every country in the world, football provides dozens of superstars. The numbers are greater when compared to any other sport, and this drives the popularity of football up. Have you ever wondered when the sport started and became popular?
Football has its origin (起源) in China and has a history of more than 2,000 years. However, modern football originally appeared in Britain in the 19th century. Folk football matches had been played before in many cities and towns, but never on a professional level.
Football became a winter sport game played in different schools. The rules were carried out by each school, and this made it difficult for players to play an official game with each other. It all changed in 1849 at the University of Cambridge that invented a set of standard rules known as the Cambridge rules of football. From that moment, a new star sport was born.
By the early 20th century, football had spread all across Europe. In 1904, FIFA was set up. There are seven original members, including France, Denmark and Spain, FIFA became the governing body for many associations in Europe.
England’s international success improved the popularity of the sport in the country. The league (联赛) in Britain was set up in 1992. From the 1990s, it became a truly impressive piece of football organization, becoming the world’s top football league in the process.
Football is obviously the most popular sport in the world. It is impossible for any other sport to take its place, especially with leagues spending billions of pounds every year to stay in the focus.

8 . Database maintenance (数据库维护) is an activity designed to keep a database running smoothly. A number of different systems can be used to build and maintain databases. Databases are used to maintain a library of information in a well-organized, accessible format (格 式).They usually are not static (静态的),because changes are constantly being made as material is added, removed, and moved around. Over time, this can cause the database to start to go wrong. Database maintenance is used to keep the database clean and well-organized so that it will not lose functionality.
One important aspect of maintaining a database is simply backing up the data so that, if anything happens, there will be another copy available. Some database systems actually do this automatically and then send the backup to another location every day, every week, or within any other set period of time. Backups are usually not enough, however.
Database maintenance includes checking for signs of corruption in the database, looking for problem areas, and checking for any detail in the database that might signal a problem. The goal is to keep the database operating smoothly for users, so that ideally they never need to think about maintenance issues. A database that is not maintained can become slow, and people may start to experience problems when trying to access records.
The maintenance of databases is generally performed by people who are comfortable and familiar with the database system and the details of the particular database, although some maintenance tasks can be performed by people who do not have experience. Numerous textbooks are available with information about database management, including how to maintain databases properly. It is also possible to take courses to learn about different database systems and how to care for databases. People can also earn certifications in specific systems which indicate a high level of competence.

9 . In the struggle to survive the ever hotter deserts of California, there are winners and losers. Among the losers are desert birds, whose populations have fallen among the heat stress of climate change. The winners, it turns out, are small burrowing mammals（穴居哺乳动物）, which take refuge from the sun underground. Researchers noted that the stable mammals populations formed a striking contrast to the extremely bad condition of birds.
But why? Birds had a higher evaporative（蒸发）heat loss. Birds were more exposed to the effects of warming, so they had higher energy costs to maintain their body temperature. However, mammals were able to reduce their body temperature by using burrows during the day.
Temperatures have risen about 4 degrees Fahrenheit on average across the area studied, but the heat affects birds and small mammals differently. As part of the study, scientists modeled each species' body temperature and cooling needs under different desert conditions. To calculate that, they measured the conductivity（传导率）of the animals' fur or feathers, and used information on their heat reducing behaviors.
The models showed that in the fight against climate change, there was not a level playing field for furred and feathered desert animals. Cooling costs—or the resources needed to maintain stable body temperature—were about 3. 3 times higher for birds than they were for small mammals, the study reported.
Small mammals have shown this remarkable stability. It's really quite interesting that, in the same region, with the same level of climate change, these two species have responded very differently to the changes taking place. Insights into the status of different species can help scientists take steps to protect them, such as increasing fire prevention in high desert areas, and enhancing water sources in those areas. The study also demonstrates that climate change is already reshaping the California desert
