1 . A solar tree is a structure like a tree that generates solar energy using photovoltaic panels (太阳能光伏板). It helps solve an urgent global challenge: Replacing greenhouse gas-emitting energy sources like oil and gas with renewable energy. But the power generation potential of solar trees is relatively limited, and their primary purpose is to raise public awareness about renewable energy by getting people to notice and interact with solar energy in new ways.

Solar trees generally have a firm metal, plastic, or stone base that extends up and out into “branches” on which solar panels are mounted. Beyond this basic structure, there is great diversity in the design of solar tree units. The solar tree’s photovoltaic “leaves” absorb sunlight, converting it into electricity that is conducted down through the trunk-like central pillar of the structure to an inside battery. Many designs feature rotating (旋转的) panels that can move throughout the day in order to obtain the greatest amount of sunlight.

Solar trees help power homes, businesses, and public services. They can create shade to help reduce the urban heat island effect and provide shelter in severe weather such as rainstorms and heatwaves, creating greater urban adapting ability in the face of climate change. They also enhance public spaces, providing charging stations, and powering streetlights.

In comparison to other kinds of ground-mounted solar panel devices, solar trees don’t require much land. They make solar energy generation possible in areas with little land that can’t support vast solar arrays, as well as places that lack sufficient rooftop space for panels. However, solar panels are much cheaper than solar trees at present and have far greater energy generation capacity. Therefore, present solar tree designs often serve as a extra source rather than as a primary energy source.

At present, solar trees aren’t designed as large-scale solar projects, which limits their ability to contribute to the low-carbon energy transition. Still, their varied designs are appealing. This makes solar trees effective at displaying and thereby educating people about solar energy, and promoting a business or organization’s commitment to renewable energy.

2 . For most people traveling abroad, their first choice is probably to make a beeline for (直奔) tourist sights. For me, I find lots of joy in grocery (食品杂货店) shopping on holiday.

As a vegetarian (素食主义者), finding restaurants that meet my needs is not always easy abroad.     1     The first thing I do, after dropping my bags off, is to go to a grocery store. That enables me to cook breakfast in the morning without walking around for hours trying to find “vegan breakfast” near me.

The variety of foods attracts me every time I travel somewhere new. In Malta, I found the most delicious chocolate-filled cakes, a product I would struggle to find even in the UK.     2     I was so delighted that I could enjoy such an unexpected treat. Another surprise was their selection of ice cream available even in the smallest grocery stores.

    3     Looking for smoked tofu and corn pancakes turns into quite a mission whenever I visit Cluj-Napoca in Romania. There is usually only one variety of smoked tofu, sold in a very small tub (食品盒) and only in the cafeteria section.     4     That is because they are never available at the smaller ones.

Grocery shopping on holiday sounds unusual. But it means being involved in the day-to-day lives of a country’s citizens. I can pretend I am a local and put myself in their shoes. I can watch kids begging their parents for sweets, an international experience that needs no language, or watch couples pick up snacks and drinks for a party on a Friday night.     5    

A．I ended up eating these every day for breakfast.

B．The challenge of finding food is interesting, too.

C．So I always make sure to book a place with a kitchen.

D．Grocery shopping was a vital part of the holiday experience.

E．It’s an act of understanding people as much as of buying food.

F．Corn pancakes always require a trip to the bigger grocery store.

G．By wandering around in a new country, I start to see what they value.

3 . Why Cooking Meals at Home Benefits More Than Just Your Wallet

When hunger strikes, the convenience of entering a fast-food restaurant or ordering takeout can be terribly attractive.     1     However, when it becomes a routine, your waistline, your wallet and your health can be badly affected. Here are four reasons to make cooking at home your option.

· It’s cheaper.

You could spend $100 at a fancy restaurant for one dinner, while the same amount of money could buy you groceries for a week. When you shop smart and get creative, you needn’t spend more than $1 on breakfast, $2 on lunch and $4 on dinner to purchase wholesome, healthy foods. Here’s how:     2    

· It may reduce your exposure to certain chemicals.

The most surprising benefit of cooking at home can decrease the amount of harmful chemicals you’re exposed to.     3     Common in takeout and fast-food packaging, those chemicals have been associated with many diseases. Food packaging can also contain other damaging compounds (化合物).

·You can better estimate calories.

    4     That is why people tend to consume extra calories when dining away from home. On the contrary, you have complete control over the food materials when you cook in your own kitchen. Choosing fiber-packed vegetables and meat containing less fat will help keep your calories under control. So will the way you cook your food. Rather than frying, choose roasting.

·    5    

Many chefs use a lot of salt while cooking. While salt can make food tastier, too much of it is linked to serious health issues like heart disease and high blood pressure. At home, you can control the quantity of salt on your plate by seasoning food in other ways, like using lemon juice. The same goes for sugar. You can use smaller quantities of natural sweeteners like honey to add sweetness to your food. Too much added sugar is linked to some diseases as well.

A．You can reduce added salt and sugar.

B．Eating out can make calorie counting tricky.

C．Buy in large quantities and stick to store-brand items.

D．Salt and sugar are both essentials in cooking delicious foods.

E．Relying on food away from home occasionally is totally acceptable.

F．People are always too engaged in their work to cook at home personally.

G．People cooking at home have lower levels of dangerous chemicals in their bodies.

4 . How to prepare for a test

In your school, tests maybe an important part of your regular classroom work.     1     If taking a test worries you, the good news is that there are many easy ways for you to prepare before it. Here’s how to get started

Make a plan

    2     This might mean committing to studying for 30 minutes for a few afternoons the week before the test. Or maybe you have more time on the weekends and want to plan extra study time then. Whatever you decide, circle out the time on your calendar so you remember.

Be organized

Studying for a test will be easier if you organize your notes and handouts ahead of time for each of your classes.     3     Consider using a separate folder (文件夹) for each subject. You can keep them at home, at school and in your backpack.

Focus on the right material

If you have learned a lot of material, first ask your teacher what information will be on the test. Use the study guide handed out by your teacher to help you figure out what you need to focus on most.     4     You may go through your notes and write key concepts on a flash card to test yourself. If there is something that confuses you, mark it and ask your teacher later.

Use smart strategies

As the day of the test approaches, be sure to get plenty of sleep the night before. When you sit down to take the exam, spend a few minutes to go through the entire test. You can start by answering the first question.     5     Finally, if you finish the test before the exams ends, go back and review all your answers to check for any mistakes. You’ve got this!

A．The correct answer may come to you later

B．Next, decide how you want to review the material

C．They are used to ensure students’ grasp of the material studied

D．You don’t want to lose focus during the test due to lack of sleep.

E．Once you have a test date, schedule your study time appropriately.

F．However, working on easier questions in a later section is a good choice.

G．This way, the information will be there for you when you need to review it.

5 . In 1665, Johannes Vermeer, one of the greatest painters in Netherlands, completed his masterpiece “Girl With a Pearl Earring.” On an April day 357 years later, Janine Strong slowed her bike to stop, paused her fitness app, and watched as the snaking line of her cycling route drew the shape of Vermeer’s masterpiece over the streets of Brooklyn.

Ms. Strong creates what has come to be known as “GPS art” — a practice that uses the Global Positioning System mapping capabilities of modern phone apps to create digital drawings with an athlete’s route. It has grown with the widespread availability of satellite tracking for use by ordinary people. In fact, the idea has been around since before the popularity of smartphones for fitness like Strava released in 2009.

In 2003, The New York Times Magazine told of how Jeremy Wood got the idea for GPS art. Mr. Wood said while he was using a GPS tracker on a flight and the plane flew in a holding pattern above Heath-row Airport, he was attracted by the pattern appearing on his Garmin GPS device. In recent years, technology has advanced enough to create visual maps in real time using a phone or smart watch.

“I get bored cycling on the same path in the same streets,” Ms. Strong said. “Creating GPS art gives me more reasons to hit the pavement, which makes cycling a lot easier. I always have a big smile on my face when it works out and I upload it and it’s done,” she added. “It’s a very satisfying feeling.”

To complete her digital vision of “Girl With a Pearl Earring,” she biked almost 50 miles around southern Brooklyn, carefully checking Strava to make sure each turn, circle, and straight line was achieving the shape of earring and head covering of Vermeer’s original.

1. What can we infer about Janine Strong in paragraph 1?

A．She tests a fitness app.	B．She is an innovative cyclist.
C．She likes pearl earrings.	D．She is a painter of some note.

2. What information can we get about GPS art?

A．It is rarely used by common people.	B．It arose after the popularity of fitness apps.

6 . For Sandra, the teachers who stuck in her mind were the ones that gave her their time and effort and really prepared her for her future.    1    In this way she hoped to provide that same, high quality education for young people and give something back.

She saw herself as a teacher who helped students and gave them love for what they had to do, whether they wanted to do it or not.    2    One of them was that a GCSE student who simply aimed to get a D at the very beginning later achieved an A in his RE exam. Every time when hearing such news, she was just smiling with pride. No one knew how much she had done for such a day.

    3    She always said to them, “Ignore that goal, and put yourself at the goal you want to achieve. Even if you are not good at your subject, it doesn’t mean that you’re going to get a D. I believe you’re going to get something far greater.”

Giving students that push to get better grade made a great difference to them. When they got it, the result was just amazing.”    4    You’ve helped them with something that’s going to make their lives much easier and better,” she explained.

Based on this teaching concept, Sandra focused on making each student a better “himself”. And what’s more, she has been among one of her former teachers and really has given something back. She once received a huge bunch of flowers with a card in it, writing, “Dear Sandra, you’ve given me the time and energy to help me get what I needed.     5    ”

A．She kept encouraging her students

B．It is useful to make friends with students

C．Her encouragement turned out to be of great use

D．It makes you feel like you’ve done your job so well

E．It is you and your teaching style that make it possible

F．So she chose to train as a teacher after college graduation

G．Looking back, there were many moments to make her proud

7 . About 600,000 people die of heart attacks at home each year. And the survival rate (存活率) of out-of-hospital heart attacks is much lower than those that happen at the in-hospital setting.

Pumpstart, a program created by students at Boston University School of Medicine (BUSM) which is meant to teach hands-only CPR (心脏复苏术) to the general public, is effective in both teaching high school students a life-saving skill and providing medical students with a chance to take part in public health and medical education after several surveys.

High school students in the Boston area who joined in the Pumpstart program completed pre-/post surveys. The pre-surveys were carried out before they watched a 60-minute training session (培训课程) on hands-only CPR. And the post surveys were done after the training session. Medical students also completed surveys judging their comfort in learning CPR both before and after they took part in the program. The high school students reported huge improvements in CPR skills following their training from Pumpstart. And it was reported that the medical students had higher confidence levels regarding their abilities to answer questions about CPR and helping new medical students to better understand the training sessions after they joined in Pumpstart.

“Getting the general public to feel comfortable performing CPR is important to overall improved survival from heart attacks,” explained Anita Knopov, a fourth-year medical student at BUSM. “Using educational resources provided by the city medical center and offering training to inner-city high school students allow medical students to serve as both educators and experienced people in CPR within the community, while making high school students interested in the healthcare field (医疗领域). That’s what Pumpstart does.”

Knopov believes Pumpstart can serve as a model for other organizations and can have a long-term (长期的) public health influence as the bystander CPR continues to be one of the most useful factors in out-of-hospital (医院之外) heart attack survival. “Although Pumpstart is offered only in Boston, we hope that our work may stimulate the development of similar programs in other areas. And in that case we can use lots of new ‘Pumpstarts’ in other regions.”

1. What is the main purpose of Pumpstart?

A．To change people’s lifestyle.

B．To train students to be healthy

C．To improve CPR skills of the public.

D．To provide medical care for communities.

2. What does Paragraph 4 imply?

A．Pumpstart improves students self-confidence

B．Pumpstart performs CPR for people independently.

C．Pumpstart obviously reduces the risk of heart attacks

D．Pumpstart encourages students to work in the healthcare field

3. What does Anita Knopov think of the program?

A．Pretty useful.	B．Widely popular
C．Partly confusing.	D．Fairly interesting

4. What does the underlined word “stimulate” in the last paragraph mean?

A．Check	B．Prevent
C．Encourage	D．Slow

9 . Chinese astronauts conducted a science lecture to millions of students on Dec. 9, 2021 from the Tiangong space station. The three astronauts, Zhai Zhigang, Wang Yaping and Ye Guangfu, showed life in space and conducted experiments in microgravity.

It was the first lecture of the Tiangong Class, China ’s first extraterrestrial (地球外的) lecture series. Its goal is to popularize space science.

“The laboratory of the space station has many conditions that the Earth laboratory does not have, such as the environment of weightlessness and radiation, ” said Wen Xin, a professor at Nanjing University of Aeronautics and Astronautics. He said that important jobs for astronauts in the space station include cell observation and maintaining plant life.

In the lecture, Ye demonstrated experiments related to cell growth in a weightless environment. He compared the growth and shape of cells in artificial gravity and zero-gravity to study their changing principles in space.

Another experiment in the space lecture was shown by Wang Yaping. She illustrated how a paper flower “bloomed” on the surface of water in Tiangong space station. She explained that the surface tension of water is magnified (放大) in space due to zero gravity.

One of the examples of surface tension on Earth is that some insects can “walk” on water. They use surface tension to “stand” instead of falling through water.

Surface tension plays a key role in product development. Researchers around the world are measuring surface tension to improve the quality of their products, according to Biolin Scientific, a science company. Paints are tailored to stick better on the surfaces they are applied to. Surface tension also has impacts in drug development.

Although the astronauts are thousands of miles away, their research does influence our life. Shi Yi, a teacher at the Beijing No. 101 Middle School, told China Daily that the space lecture was “an eye-opening experience that would arouse students’ interest in science”.

1. What makes the space laboratory special?

A．It is operated by a professor.

B．It has a unique experiment environment.

C．It broadcasts experiments to students.

D．It promotes cell growth.

2. What can we learn through Ye’s cell experiment in space?

A．The rules of cell growth.	B．The secret in a weightless environment.
C．The conditions of cell growth.	D．The differences between the universe and the earth.

3. What can we say about surface tension?

A．It can speed up flower blooming.	B．It is related to product quality.
C．Paints have an influence on it.	D．Drugs are used to measure it.

4. Which of the following is the best title of the passage?

A．Special Laboratory Environments	B．Examples of Surface Tension
C．Learning from Space	D．Lectures about Cells
