The example of a foreign teacher who volunteered to help fight the wildfires in Chongqing's Beibei District with other local residents has touched many.
In the unbearable heat and drought conditions，multiple wildfires hit parts of Chongqing.On Sunday night，a forest fire broke out and spread in Beibei District.The local government issued an urgent call for volunteers with certain skills and experience，such as chain saw（链锯）operation，to join in the firefighting.Chain saws were used to create fire barriers.
"I was happy to help，" said Francis Stonier，a professor in a university. "I used to cut trees around my yard and neighborhood and had volunteered many times in the US in the past."
Stonier found a translator-50-year-old He Wu，a foreign language professor-who also signed up to fight fires.Soon after arriving at the volunteer area，the pair were assigned to one of the chain saw groups-examining and adjusting chain saws.
"Stonier is responsible and focused，and is doing a really good job，" said He，adding that Stonier checked each chain saw carefully，to see if it was too tight or too loose. "Wherever I went，the volunteers and local residents gave me a big thumbs-up.It was an unforgettable experience，" Stonier said.
Thanks to the joint efforts of fire and rescue workers，as well as volunteers and residents，the scaring wildfire in Beibei had been put out as of Thursday night.
"It was great to see such an outpouring of help in the extreme heat，" Stonier said，noting that he was impressed with the number of locals who came to help.Motorcyclists gave up their jobs to transport materials and people up and down the mountains.Others gave their time to carry heavy supplies，prepare and serve meals or help organize.

Carbon dioxide emissions from transportation are now thought as the top source of green-house gases.One of the most effective ways to reduce your carbon footprint is to reconsider how much，and how often，you travel.
Going car free for a year could save about 2.6 tons of carbon dioxide，according to a study from the University of British Columbia.How can you stop using a car？Try taking a train，bus or better yet，riding a bike.
But let's be realistic.You will likely need to use a car this year.So，when you do，here are some tips to make your trip more climate-friendly.Driving efficiently can help to reduce emissions.Go easy on the gas and brakes and drive like you have an egg under your foot.Regularly service your car to keep it more efficient.Keeping your tires pumped correctly can reduce emissions.Low tire pressure will hurt your fuel economy.Air conditioning and frequent city driving can make emissions go up So cut down on these as often as possible.Use cruise control（定速巡航）on long drives-in most cases，this can help to save gas.Don't weigh your car down with extra things that you don't need on your trip.
Fly often？Taking one fewer long round-trip flight could reduce your personal carbon footprint significantly.If you use public transportation often and fly less，your carbon foot print might still be relatively sustainable，but if you drive and fly a lot，your emissions will be higher.If you can't avoid flying，you can them by donating money to sustainable projects，such as supplying efficient stoves to rural homes，or projects which help farmers deal with crop waste environmentally.
8. What does the author think of going car free？ ______
A. Efficient. B. Costly. C. Impractical. D. Reliable.
9. Which can be adopted to save fuel of your car？ ______
A. Maintaining your car properly.
B. Using cruise control in the city.

D. Getting rid of all the necessary loads.
10. What does the underlined word "offset" in paragraph 4 mean？ ______
A. Put up with. B. Team up with. C. Set foot in. D. Make up for.
11. Which is the best title for the text？ ______
A. Lower carbon footprint in transportation
B. How to reduce your carbon footprint
C. Reduce carbon footprint by all means
D. How to save fuel when driving cars

Chinese astronauts have successfully grown rice seedlings（幼苗）aboard the Tiangong space station and this experiment may offer key insights into how astronauts can grow food to support long—term space missions，experts said on Monday.This experiment is the first to produce the complete life cycle of the plant，which begins with a seed and ends with a mature plant producing new seeds.
The breakthrough was conducted in the Wentian space laboratory，which was launched into orbit on July 24，2022.Three astronauts were conducting the experiment smoothly and testing the plants according to the plan.
"The rice seedlings are growing very well，" said Zheng Huiqiong，a researcher of the task，adding that the experiment also contained seedlings of a small flowering plant often used by scientists to study mutations（变异）. "The astronauts will keep monitoring the plants，and if is successful，they will collect the newly produced seeds and bring them back to Earth for further studies，" she noted.
The flowering stage is crucial for plant reproductive development. "We want to investigate how microgravity can affect the plant flowering time and whether it is possible to use the microgravity environment to control the related process，" she said.
Since the 1980s，China has been taking seeds of rice and other crops to space to help them mutate and produce higher yields once they were planted on Earth.But growing rice in orbit is a different challenge due to the tough conditions of space such as microgravity and lack of air.
Rice has been a main food for astronauts since the early days of space exploration.Freeze—dried chicken and rice was the menu for the Apollo 11 mission，which carried the first humans to land on the moon in July 1969.
"But if we want to land on and explore Mars，bringing food from Earth is not enough to provide for the astronauts' long journey and mission in space.We have to find a food source for long term space explorations，" Zheng added.
12. What's the significance of Chinese recent space rice experiment？ ______
A. It enables human beings to move to another planet.
B. It helps people get a better idea of the human life cycle.
C. It inspires more other countries to do space explorations.
D. It makes it possible to carry out long—term space missions.
13. What does the underlined word "it" in paragraph 3 refer to？ ______
A. The mutation. B. The experiment.
C. The exploration. D. The space mission.
14. Why have crop seeds been brought to space since the last century？ ______
A. To promote genetic changes and increase crop harvest.
B. To figure out how to create an earth—like environment.
C. To study the impact of microgravity on crop growth.
D. To develop new crop species with strong ability to adapt.
15. Where is the text most probably from？ ______
A. A medical report. B. A fashion magazine.
C. A science newspaper. D. A history book.
