Here are 4 attractive places worth your visit.ChurchillChurchill is a town with the nickname "Polar Bear Capital of the World”, where tourists can safely view polar bears from special vehicles in the autumn and winter. Thousands of beluga whales, which move into the warmer waters of theChurchill Riverduring July and August, are a major summer attraction. Churchill is also a destination for bird watchers from late May until August.Niagara FallsNiagara Fallsis a group of three waterfalls, crossing the border betweenCanadaand theUnited States. The largest of the three is Horseshoe Falls, also known asCanadian Falls. Niagara Falls illumination（彩灯）is a must for any visitor! Every night of the year, the three waterfalls are illuminated in color1 s creating an attractive scene that can be viewed from near and far.VancouverVancouverisCanada's third-largest city, always named as one of the top five worldwide cities for its comfortable environment and quality of life.Vancouverhas an active nightlife scene, whether its food and dining, or bars and nightclubs. From mid-June to early July, the Vancouver International Jazz Festival features 300 concerts, including a free opening Downtown Jazz Weekend.OttawaThe capital ofCanadais situated on the banks of theOttawa Riverand has a lot ofEnglish buildings in it. It is a beautiful city which has the Parliament buildings on the banks and English influenced houses and parks around. There are museums and art galleries that will give you a complete knowledge of the English culture there. It is really the heart ofCanada. So if you are a history and art loverOttawais the best choice for your visit inCanada.1. If you want to watch birds, which place will you choose to visit?A. Churchill.B.Niagara Falls.C. Vancouver.D.Ottawa.2. What is the best season for visitingVancouver?A. Spring.B. Summer.C. Autumn.D. Winter.3. What doNiagara FallsandVancouverhave in common?A. They are both famous for natural scenery.B. The best visiting time are both at nights.C. They are both located inCanadaentirely.D. The tickets there are both free at weekends.BWe all know that a healthy lifemeans getting both plenty of exercise and enough good-quality sleep, but reality often gets in the way. The new research indicates that doing enough exercise could make up for some of the unhealthy impacts of bad sleep. While the health benefits of exercise and sleep are nothing new, it's the relationship between them that is interesting in this particular study — it could even give doctors another option to suggest for patients dealing with sleep problems.“We found those who had both the poorest sleep quality and who exercised the least were most at risk of death from heart disease, stroke, and cancer,” says epidemiologist Bo-Huei Huang, from the University of Sydney in Australia.Participants were grouped into three levels of physical activity (high, medium or low) and were also given a sleep quality score from 0-5 based on the amount of shut-eye they got, how late they stayed up, insomnia, snoring and daytime sleepiness.Those with the highest risk of dying from cancer or heart disease during the study period were those with the worst quality sleep and who didn't meet the WHO recommended guidelines for exercise. That risk went down for people with poor quality sleep but who did meet the exercise guidelines.In the case of all forms of cancer, for example, those at the unhealthiest end of the sleep and exercise scale had a 45 percent higher risk of dying from cancer than those with good sleep scores who kept physically active. However, that risk just about disappeared for those who didn't score well on sleep but did score well on physical activity.For now it's not clear why more exercise might make up for poor sleep, as far as our health goes. It could be that the increased activity iscounteractinginflammation (炎症), or reducing irregularities in glucose metabolism, suggest the researchers.“Considering that physical activity is perhaps more modifiable than sleep, our study offers people morehealth incentives to be physically active.” says population health researcher Emmanuel Stamatakis, from the University of Sydney.4. This research is of particular interest in that ________.A. it’s in this study that exercise is known to be beneficial to sleep.B. this study offers people more health treatments to be physical active.C. it could enable doctors to cure patients of their sleeping condition.D. the relationship between exercise and sleep is updated in this study.5. Which of the following statements istrueaccording to the passage?A. Those who had the poorest sleep quality were most at risk of death from heart disease.B. Those scoring lowest on sleep and exercise scale were more likely to die from cancer.C. There’s no risk of cancer for those who didn't sleep well but did score well on physical activity.D. It's evident that in terms of health more exercise could make up for poor sleep.6. What does the underlined word in Paragraph 6 mean?A. interactingB. increasingC. preventingD. causing7. Where can this passage most probably be taken from?A. A research findings reportB. A medical examination reportC. A poor sleep study reportD. A physical activity study reportCTexas has been one of the most restrictive gun-rights states in America.Thanks to a new law,however,the state will be one of the most relaxed,to the degree that police are discouraged from even asking about someone's guns. And if they do, they may not have much power to do anything if the person refuses to show a license.To be sure, the law is strict in its own way,offering a model for regulation. Under the law, open-carry citizens have to be licensed, a process that includes safety and shooting tests. They also have to show no prior psychological problems, and they have to be at least 21 years old.It is true that gun violence dropped sharply after restrictive laws were put in place in countries like Great Britain and Australia. However,the US public seems more interested than ever in weapons and the power they convey,despite gun control groups' concern over the increase of violence. Most states in America have steadily expanded gun rights since the end of a 10-year assault(攻击)weapons ban in 2004. Black Friday this year saw the biggest gun cache(贮存)ever purchased in one day.Considering those trends,there's a heated debate about whether the new Texas law is a model piece oflegislation(立法)for a changing America,or a walking disaster just begging for trouble. As the law doesn't provide any punishment for those who refuse to show a license to a police officer, critics fear that officers may find it tough to handle potentially deadly situations. After all, armed citizens will no longer be considered suspicious, even though a lot of people might be alarmed by the sight. Most police in Texas have been told to not engage gun carriers unless they are doing something questionable or appear drunk.For sure,New Year's Day will be an exciting one for Texas gun owners. What's not yet known is how the rest of Texas will respond.8. All of the following are required in the new Texas law for open carry EXCEPTA. age limitB. mental conditionC. online registrationD. gun-operating skills9. What is mainly talked about in Paragraph 3?A. The reason for putting forward the new Texas law.B. The present situation of gun possession in America.C. The impact of the assault weapons ban in 2004.D. The inaction of the US government as to gun control.10. What do critics think the new Texas law will probably lead to?A. Heavier workload for policemen.B. Disrespect for officers.C. Lack of trust among citizens.D. Difficulty in crime prevention.11. What is the author's attitude towards the new Texas law?A. Negative.B. Cautious.C. Indifferent.D. Approving.DA dog spentthe lastfour years of his life waitingat a crossroad in the Thai city ofKhon Kaenas if waiting for someone. People originally thought the dog had been abandoned, but then realized that he looked healthy, sopeople asked around about him. It turned out that the dog had indeed been spending most of his time around that crossroad, but a woman had been coming round regularly to bring him food and water.One day, while photographing the dog everyone called Leo, a reporter met the woman who had been taking care of him.

近日，中国农业科学院植物保护研究所粮食作物害虫监测与控制创新团队创新性的将氧化石墨烯作为农药的增效剂，显著地提高了农药的生物活性。
相关研究成果以封面文章在线发表在《环境科学：纳米（Environmental Science: Nano）》上。
氧化石墨烯（GO）是一种碳基纳米材料，已应用在医学、环境科学等领域，在植物保护领域的应用鲜有报道。
该研究选取对农业生产上为害较为严重的鳞翅目昆虫亚洲玉米螟为模式昆虫，以生产上常用的农药吡虫啉、高效氟氯氰菊酯和杀虫单为代表性农药，详细探究了GO对农药的增效作用及增效机制。
该研究通过静电作用将三种农药负载到GO上形成GO-农药的复合物，可有效地提高农药对亚洲玉米螟的生物活性。
GO对农药的增效机制分为3种，一是GO 尖锐的片层结构可机械地损伤昆虫的体壁，造成昆虫迅速失水；二是损伤的体壁为农药对昆虫体壁的穿透提供新的通道；三是吸附了农药的GO可沉积到玉米螟的体壁上，提高了农药的利用率。
该研究得到中国农科院创新工程、国家重点研发计划项和国家玉米产业技术体系专项资金的资助。
