Charrier said they're encouraging citizens to try electric cars that can travel about 70 kilometres before the batteries need recharging Hundreds of officials from towns and cities across North America have called to ask about Leaf Rapids'historic by-.law(地方法规)that banned plastic bags last April..The town was getting so many calls that it posted the by-law on its website.

Leaf Rapids'move also caused threats()of legal action from the CPIA(Canadian Plastics Industry Association)."It's our opinion that Leaf Rapids'actions are illegal," Association spokeswoman Cathy Circo said."But nothing has come of it,"Charrier added. Circo noted that Leaf Rapids has only a half-dozen stores so its ban would be difficult to follow elsewhere

Research led by the University of Kent,UK,found that destruction of their living environments,and the subdivision (of large farms into smaller ones,are the biggest dangers. "This is because there is a higher risk of human activities and hunting in areas where there are more farms;a greater pressure on natural resources through increased cutting trees and livestock farming(畜牧业);and even competition for food from animals kept as pets,”said Dr Nicol s G Ivez,who is now a lecturer at the Pontificia Universidad Catolica de Chile

Research led by the University of Kent,UK,found that destruction of their living environments,and the subdivision (细分) of large farms into smaller ones,are the biggest dangers. “This is because there is a higher risk of human activities and hunting in areas where there are more farms;a greater pressure on natural resources through increased cutting trees and livestock farming (畜牧业);and even competition for food from animals kept as pets,” said Dr Nicol s G lvez,who is now a lecturer at the Pontificia Universidad Católica de Chile
More than two-thirds of Chile's rainforests have been lost over 25 years.However,through a series of questionnaires camera-trap data and remote-sensed pictures the researchers found that the guina is adaptable to forest loss in a surprisingly way. They say large,intensive agricultural areas are actually suitable for the guina and should not be looked on as poor quality habitats."This is because there are many unfarmed areas that provide shelters.food resources and suitable conditions for taking care of young,"they say. Another threat is illegal killing by humans.The cat is thought little of in the countryside over fears that it will kill chickens.Questionnaires showed that 10%of farmers had killed a guina in the last decade. "This suggests that illegal killing is much less of a threat to their survival than the subdivision of farms,"said Prof Zoe Davies,from the Durrell Institute of Conservation and Ecology (DICE)at the University of Kent. 28.Which characteristic is unique to the guinas? A.They are as big as the pet cats. B.They live only in South America. C.They are endangered wild animals. D.They prefer to living in the rainforests. 答案B 解析推理判断题。根据第一段中的The wildcat lives only in central and southern Chile and in a long narrow area of Argentina.”,并结合常识可推断出B项正确,因为智利和阿根廷都属于南 美洲。 29.Why do people in the countryside have a custom of killing guinas? A.Because people want to take more land form guinas. B.Because guinas are thought to bring bad luck to people. C.Because guinas are considered pests as they can steal chickens. D.Because guinas are looked on as evils as they can spread diseases. 答案C 解析细节理解题。根据第六段叙述可知,农村地区的人对山原猫持负面看法是因为这种猫经 常捕食他们饲养的鸡。 30.What does the underlined word"habitats"in paragraph 5 refer to? A.The suitable foods that an animal mainly lives on. B.The obvious reasons why an animal is actually in danger. C.The terrible factors that affect animals'safety and health D.The natural environments where an animal normally lives 答案D 解析词义猜测题。结合该词所在的句意可知,大型集约化的农田实际上是适合山原猫生活 的.故此不能将其看作是山原猫的劣质的栖息地.因为这里有许多未开垦的区域为山原猫提供 屁护和食物.故habitat意为“栖息地”。 31.What conclusion does the research show about the guinas? A.They are able to survive near human settlements on agricultural lands. B.Large agricultural lands are not suitable for the guinas to survive in. C.Guinas prefer the agricultural lands to traditional rainforests. D.Guinas need to develop new skills to adapt to the change of climate. 含案A 解析推理判断题。根据第四、五段的叙述可知,山原猫已经很好地适应了其栖息地的变化, 在人类居住地附近的农田里能生存下来。 D We're often reminded of the importance of preserving the planet as we see it for future generations-and children at St Oswald's CE Primary School Chester certainly agree.

Nine-year-old Isobel Kelleher from the school’s Hummingbirds class thinks adults need to take note.“Sometimes they can be busy and I don’t think they think they can make a
difference.but if everyone does a little bit it all adds up."she tells HuffPost UK."We started looking at plastic pollution in our oceans and the things like plastic bags that are polluting them," she says."Fish can eat the plastic and they can die,or we might even eat the fish ourselves. Mr Timms,Isobel's teacher,has been leading a new project at the school which lets children loose creatively to raise awareness of the need to be more environmentally friendly.The entire Hummingbirds class,which is made up of 9-and 10-year-old pupils,has been busy writing poems and creating online video advertisements to warn adults about the serious situation of our oceans and wildlife. Mr Timms thinks children have an important role to play in teaching us how to take care of the things around us."We sometimes overlook how much we can really learn from children,"he says."It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic,and to recycle more,and even stopping them using plastic straws.' Mr Timms is proud of his Hummingbirds class."The message that they would like to send to the world is simple:stopping this isn't someone else's job,and it won't be OK if we just leave it” 32.What can we infer about adults according to Isobel Kelleher? A.They just pretend to be busy. B.They haven't done their part well. C.They can do nothing to stop pollution. D.They have started to care about the ocean. 答案B 解析推理判断题。根据第二段内容,尤其是第一句Nine-year-old Isobel Kelleher from the school's Hummingbirds class thinks adults need to take note.”可知,学校“蜂鸟班”里9岁的 Isobel认为成年人需要注意环保问题,由此可推知,成年人在环保问题上做得不够好。故选B 项。 33.What is the purpose of the school's new project? A.To help adults to learn more about their kids. B.To persuade students to stop using plastic bags C.To teach students how to write poems creatively. D.To remind adults to be friendly to the environment 答案D 解析细节理解题。根据第三段中的to warn adults about the serious situation of our oceans and wildIife可知,“蜂鸟班”的学生们一直忙着写诗和制作在线视频广告,提醒成年人关注海洋和 野生动物的危险处境.由此可知,该项目旨在提醒成年人要注意环保问题。故选D项。 34.Why does Mr Timms mention parents in paragraph 4? A.To attract people to support his work. B.To have adults care about education. C.To show the effects of the project. D.To prove kids are creative in teaching. 答案C 解析推理判断题。根据第四段中的"It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic,and to recycle more,and even stopping them using plastic straws..”可知,真的很难相信有家长说孩子们要求他们停止使用塑 料,要求他们回收更多的塑料,甚至阻止他们使用塑料吸管,由此可推知,该段提及家长旨在说 明该项目对成年人的影响。故选C项。 35.What is the best title for the text? A.An Inspiring School Project B.An Appeal to Stop Using Plastic C.Serious Situations of Our Planet D.Adults'Ignorance of the Environment 答案A 解析主旨大意题。第三段第一句Mr Timms,,Isobel's teacher,.has been leading a new project at the school which lets children loose creatively to raise awareness of the need to be more
