1、2024年步步高高考英语大一轮复习(新人教版)选择性必修第一册选择性必修第一册Unit 1People of Achievement.阅读理解ABanff National Park is home to an amazing wildlife population.But the busy TransCanada Highway that cuts through the park is a hazard to the lovely animals.To address the problem,Banff first put up wildlife fencing on either sid
2、e of the highway to discourage animals from entering the busy road.Then,since 1996,six wildlife overpasses and 38 underpasses have been opened to help the animals cross the highway in safety.I was fortunate to visit Banffs Red Earth Overpass with Trevor Kinley,the project manager of Parks Canada.He
3、told me that so far,they had documented 10,000 safe animal crossings on this overpass alone.“Some animals have learned how to use the crossings much more quickly than others.Black bears are the fastest learners,followed by deer.Wolves and lions take the longest to work out how to use them,”Kinley sa
4、id,laughing.“But those animals that are slower to adapt are usually more capable and determined to figure out the safest way to cross those overpasses and underpasses.”There is some criticism(批评) that channeling so much wildlife into a few bridges and tunnels is like making a trap for the animals,of
5、fering big animals an easy meal on either side.“But research has shown that this is not the case,”Kinley assured me.“There are no more killings around the crossings than anywhere else in the park.”Walking over the TransCanada Highway and then walking underneath through one of the tunnels,I was amaze
6、d to see the fresh tracks of black bears,wolves,deer and many kinds of smaller animals.Somehow,I was so happy to see all these animal footprints,knowing that all this wildlife was passing safely under and over the longest road in Canada.Hopefully,the success of the wildlife crossings in Banff will c
7、ontinue to inspire similar solutions around the world,where human pressure on wildlife continues to grow.1Which of the following best explains the underlined “hazard”in paragraph 1?AShelter. BMessage.CAnswer. DDanger.2What does Trevor Kinley say about those wolves and lions?AThey are stupid animals.
8、BThey are cautious learners.CThey are very dangerous.DThey are good at adapting.3What are the critics worried about?AThere are too many bridges and tunnels.BMany animals will not use the crossings.CMore killings might happen at the crossings.DIllegal hunting might be encouraged in the park.4How does
9、 the author feel at the end of the visit?AConcerned. BDisappointed.CShocked. DDelighted.BPlants dont have ears or a central nervous system,but new research out of the University of Missouri has demonstrated that they might still have the ability to “hear”More specifically,plants have been shown to e
10、xhibit an immune response to the mere sound of a hungry insect.For the study,researchers played the sound of a caterpillar chewing to a group of plants,which caused slight vibrations(振动) on the plants leaves.The plants were able to recognize these vibration patterns as danger,and responded by mounti
11、ng the appropriate immune response.In other words,it appears that plants can “hear”themselves being chewed on.Researchers assume that plants achieve this remarkable ability thanks to proteins that respond to pressure found within their cell membranes.Vibrations cause pressure changes within the cell
12、,which can change the behavior of the proteins;however,additional study will be required to confirm or deny this theory.Once researchers identify the exact mechanisms at play in this process,it could lead to advances in crop protection.Farmers could potentially learn to use sound to cause a plants n
13、atural chemical defenses against insect threats,rather than turning to poisonous chemicals.“We can imagine applications of this where plants could be treated with sound or genetically engineered to respond to certain sounds that would be useful for agriculture,”said study author Heidi Appel.The stud
14、y adds to the growing list of ways that plants have been shown to sense their environments.They are not the boring organisms that many people assume they are.For instance,some plants are able to communicate with each other and signal upcoming danger to their neighbors by releasing chemicals into the
15、 air.Plants can respond to light (think about sunflowers) and temperature.Some can even respond to touch,such as the Venus flytrap(捕蝇草),which snaps shut when an insect stimulates its hairs.5Why did researchers carry out the study?ATo find out if plants can react to sounds.BTo learn how plants recogn
16、ize dangers.CTo discover if plants can shake their leaves.DTo see how plants improve immune systems.6Whats the potential use of researchersdiscovery?ATo remove insects.BTo protect crops.CTo treat plant diseases.DTo produce chemicals.7What does the author intend to tell us in the last paragraph?ATher
17、e are more plants than we know.BLots of secrets about plants remain unclear.CPlants fit in well with their environments.DPlants are more active than we think.8What can be the best title for the text?ACan Plants“Talk”with Each Other?BHow Do Plants Make Use of Sounds?CCan Plants“Hear”Themselves Being
18、Eaten?DHow Do Plants Defend Themselves Against Attacks?CThe Tiangong space station is a space station being constructed by China.The construction of the station is based on the experience gained from its pioneers,Tiangong1 and Tiangong2.The first module(舱),the Tianhe core module,was launched on Apri
19、l 29,2021,followed by multiple crewed and uncrewed missions and two more modules to be launched by 2022.According to China Manned Space Agency(CMSA),which operates the space station,the purpose and missions of Tiangong space station are listed as:breakthroughs in key technologies such as permanent h
20、uman operations in orbit,longterm autonomous spaceflight of the space station,life support technology and development of technology that can aid future deep space exploration.The Tianhe Core Cabin Module(CCM) provides life support and living quarters for three crew members and provides guidance and
21、navigation(导航) for the station.The module also provides the stations power.The station is equipped with a small kitchen for food preparation and the firstever microwave oven in the spaceflight,so that astronauts can always have hot food whenever they need.120 different types of food,selected based o
22、n astronauts preference,are stored aboard.Chinas intention to build its own space station was amplified(增强) after NASA refused Chinese participation in International Space Station in 2011.On February 22,2017,CMSA and Italian Space Agency(ASI) signed an agreement to cooperate on longterm human spacef
23、light activities.The agreement holds importance due to Italys leading position in the field of human spaceflight with regard to the creation and development of the International Space Station and it shows Italys increased expectations of Chinas developing space station program.Tiangong is also expec
24、ted to host experiments from many other countries.9What do we know about the Tiangong space station?AIt aims to build a core module.BIts construction has been finished.CSelfcontrolled flight is impossible.DIt can further assist space exploration.10What is paragraph 3 mainly about?AFood stored aboard
