1 . Acid rain is very harmful to the environment because it makes living things die. Acid rain affects life in the water as well as life on the land. It is even worse in the water because the fish need the water to breathe. When the water gets polluted, the fish get sick and end up dying.

All rainwater contains some level acidity. Acidity is measured by PH, which stands for potential of hydrogen(氢). The PH scale measures the amount of acid in a substance. PH is measured on a scale from 0 to 14, with 7 being neutral(中性的). The lower the number is on the PH scale, the more acidic that substance is. Normal rainwater has a PH of 5. 6. When the PH level of rainwater goes below 5. 6, it is considered acid rain.

All of the sea life will die when the water becomes too acidic. For example, all fish will die when the water goes below a PH of 4. 5. Most of the frogs and insects that live around the water will also die when the water reaches a PH of 4. 5. When the water has a PH of 5. 5, all of the bottom-dwelling bacterial decomposers(分解体), animals that eat the remains of the food that other animals don’t want, will begin to die. When these decomposers die, they will leave the under-composed food on the bottom. This will make the water dirty and polluted. All fresh water shrimps(虾) will die when the water has a PH of 6. 0. Aquatic plants will grow the best when the water has a PH between 7. 0 and 9. 2. If the acid rain problem gets worse. all of the sea life will eventually be gone.

1. What can we know about acid rain?

2 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

The Zuo zhuan, generally translated as Zuo Tradition, is     1     ancient Chinese narrative (叙述) history that is considered as a commentary on the ancient Chinese chronicle (编年史), the Chunqiu—the Spring and Autumn period (770-476 BC). The Zuo zhuan focuses mainly on political, social and military     2     (event) of China’s history. It explains its historical background, and contains much rich and lively     3     (describe) of the Spring and Autumn period history and culture. The Zuo zhuan has more Chinese sayings and idioms     4     any other classical work, and its simple flowing style came to be held as a model of elegant classical Chinese. It was, for many centuries, the primary text through     5     the Chinese gained an understanding of     6     (they) ancient history.

Although the Zuo zhuan     7     (regard) as “a masterpiece of great historical narrative” for a long time, its early textual history is largely     8     (know) and its author has been widely debated. The “Zuo” of the Zuo zhuan’s title was     9     (traditional) believed to refer to one “Zuo Qiuming”—a figure of the 5th century BC thought     10     (be) a blind student of Confucius—but there is little actual evidence to support this. Modern scholars now generally believe that the Zuo zhuan was originally an independent work finished during the latter half of the 4th century BC that was later rearranged as a commentary to the Chunqiu.

4 . Chou doufu is a fermented (发酵的) tofu with a strong smell but good flavour. The street snack is usually sold at night, served out of a small bowl and toothpicks (牙签) to pick it up.     1    .

Chou dou fu was invented by a man named Wang Zhihe during the Qing Dynasty. He studied to become a local officer, but tried and failed many times. Every time he left his hometown to take the exam in the capital city, he would end up using all of his money for travelling and be left with nothing to buy food.     2    , Wang Zhihe decided to make a living in the capital city while preparing for the next year’s exam.

His family back home was wealthy from their tofu factory business.     3    . He bought some simple tools to make it in order to sell it on the street. During that time, the summer heat was causing the fresh tofu that he didn’t sell to become moldy (发霉).     4    . He decided to cut the tofu into smaller pieces, dry them in the sun and then pickle (腌渍) them with salt. They were stored in a jar until autumn came. The moment he opened the jar, he was hit with the special smell of fermented tofu that had become grey.     5    , so he sent them to the neighbors who found that they enjoyed the dish, too. From then on, chou doufu has become a famous street snack.

6 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Once upon a time, there was a boy who always enjoyed listening to his mother’s story about the statue (雕像) standing beside their house.

The statue’s name was Miriad, who was the symbol of kindness. People who walked by the statue showed their respect through bowing (鞠躬) in front of Miriad’s statue. It became a tradition in their village that everyman who died due to helping others would be honored as Miriad, and would be remembered by all the people.

One night, the boy asked his mother how Miriad gained his respect from all the people in this village. “He was just a simple man,” his mother said. “He helped people selflessly, thinking others first.” “Well, I can also do that,” the boy proudly told his mother. His mother continued, “That is the reason why people made Miriad a statue, for you child to copy and not to forget.”

One morning, the boy saw a little girl crying under an apple tree. “Why do you cry?” the boy asked. “I was trying to get myself some fruit from this apple tree and suddenly I fell down from it,” the little girl explained. “Let me do it for you,” the boy said. He started to climb up the tree and picked as many apples a she could. After a while, the boy jumped down from the tree and gave all the apples to the little girl.

7 . Hidden in the trees, behind the leaves, look closely and you’ll see eyes staring back at you. This is SlothBot, a robot inspired by the famously slow animal-sloth (树獭).

For the next several months, visitors to the Atlanta Botanical Garden will be able to observe the testing of the new high-tech tool in the battle to save some of the world’s most endangered species. Researchers are testing the SlothBot near the Garden’s popular Canopy Walk.

Built to take advantage of the low-energy lifestyle of real sloths, SlothBot demonstrates how being slow can be ideal for certain applications. Powered by solar panels and using innovative power management technology, SlothBot moves along a cable strung between two large trees as it monitors temperature, weather, carbon dioxide levels, and other information in the Garden’s 30-acre midtown Atlanta forest.

“Slowness is a design principle of SlothBot,” says Magnus Egerstedt, professor and chair in the Georgia Institute of Technology’s School of Electrical and Computer Engineering. “That is not how robots are typically designed today, but being slow and energy-efficient will allow SlothBot to stay in the environment to observe things we can only see by being present continuously for months, or even years.”

About three feet long, SlothBot’s imaginative 3D-printed shell helps protect its motors, gearing, batteries and sensing equipment from the weather. The robot is programmed to move only when necessary, and will locate sunlight when its batteries need recharging.

“The most exciting goal we’ll demonstrate with SlothBot is the union of robotics and technology with conservation,” says Emily Coffey, vice president for conservation and research at the Garden. “We do conservation research on endangered plants and ecosystems around the world, and SlothBot will help us find new and exciting ways to advance our research and conservation goals.”

“SlothBot could do some of our research remotely and help us understand what’s happening with pollinators(传粉者), interactions between plants and animals,   and other phenomena that are difficult to observe otherwise," Coffey adds.

1. What do the researchers expect SlothBot to do?

A．Guard the garden.	B．Attract visitors.
C．Protect real sloths.	D．Help endangered species.

2. What does the underlined word “That” in paragraph 4 probably refer to?

A．SlothBot.	B．Slowness
C．A design principle.	D．A low-energy style.

3. What can we know about SlothBot?

A．It always stays still.	B．It can pollinate the plants.
C．Its shell provides protection for itself.	D．Its design will be used to study the ocean.

4. What may be the best title for the text?

A．A Slow-moving Sloth Begins Life in a Garden

B．A New Robot Helps Raise Endangered Animals

C．A New Study Aids Conservation Efforts in Atlanta

D．A Conservation Robot Slowly Monitors Endangered Species

9 . Last year, Mia McCarthy and Chase Robbins, both college students in the Iovine and Young Academy of USC(University of Southern California), were sitting around at 11 pm when they started craving for candy. The pair immediately ordered from DoorDash (a takeaway app) to settle the sweet tooth. After carefully tracking the driver for 45 minutes, the driver cancelled the delivery. This moment made them realize there had to be a quicker way for customers to order snacks without driving to a grocery store.

McCarthy and Robbins then set up their app — Handle, a service that delivers snacks, drinks, ice cream and household necessities to the USC area within 15 minutes. They spent the summer of 2021 exploring the process of starting a business. “We were trying to push things forward so fast that we started to hate weekends because no one else was working so we couldn’t contact suppliers,” Robbins said.

The major difficulty they faced was to figure out what strategy made the most sense for ordering and customer convenience. They decided the best choice was to hire engineers to build a fully functional app.

Although they made a lot of preparations, the app crashed on the night of its official launch in late August, letting McCarthy and Robbins feel hopeless. Even so, they didn’t give up. Robbins spent the following 10 days coding the app so that the team could ensure success for their second launch. Mia’s artistic background, combined with Robbins’ engineering background, allowed them to work well together. “It was really hard and emotionally challenging,“ McCarthy said. “I’m really glad that we were able to make it.”

The early days of the business were nothing but difficult. McCarthy and Robbins delivered orders, worked on marketing and spoke with suppliers to improve the products the store was selling. They now have an entire group of deliverers working from 4 pm to 1 am daily, delivering thousands of products to people in the surrounding campus community.

A．The app Handle didn’t come easy.	B．Robbins is more capable than McCarthy.
C．McCarthy and Robbins often felt hopeless	D．I’s easy to give up when staring a business

4. Which of the following words best describe Mia McCarthy and Chase Robbins?

A．Kind and curious.	B．Determined and hard- working
