31.Which is the best title for the text?A.How to save fuel when driving carsB.How to reduce your carbon footprintC.Reduce carbon footprint by all meansD.Lower carbon footprint in transportationDChinese astronauts have successfully grown rice seedlings()aboard the Tiangongspace station and this experiment may offer key insights into how astronauts can grow food tosupport long-term space missions,experts said on Monday.This experiment is the first toproduce the complete life cycle of the plant,which begins with a seed and ends with a matureplant producing new seeds.The breakthrough was conducted in the Wentian space laboratory,which was launchedinto orbit on July 24,2022.Three astronauts were conducting the experiment smoothly andtesting the plants according to the plan."The rice seedlings are growing very well,"said Zheng Huiqiong,a researcher of thetask,adding that the experiment also contained seedlings of a small flowering plant often usedby scientists to study mutations ()"The astronauts will keep monitoring the plants,andif it is successful,they will collect the newly produced seeds and bring them back to Earth forfurther studies,she noted.The flowering stage is crucial for plant reproductive development."We want to investi-gate how microgravity can affect the plant flowering time and whether it is possible to use themicrogravity 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 themmutate and produce higher yields once they were planted on Earth.But growing rice in orbit isa 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.Freezedried chicken and rice was the menu for the Apollo 11 mission,which carried the first humansto land on the moon in July 1969."But if we want to land on and explore Mars,bringing food from Earth is not enough toprovide for the astronauts'long journey and mission in space.We have to find a food sourcefor long-term space explorations,"Zheng added.32.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.【高二英语第6页（共10页）】·23-134B·
