1、江苏省江苏省苏州市苏州市 2022-2023 学年学年高高二二第一学期期中考试英语第一学期期中考试英语模拟模拟试题试题 一、阅读理解一、阅读理解 (共两节,满分(共两节,满分 40 分)分) 第一节(本题共 15 小题; 每小题 2 分, 满分 30 分) 阅读下列短文,从每题所给的 A、B、C、D 四个选项中,选出最佳选项。 (A) Scientists say they have developed a system that uses machine learning to predict when and where lightning will strike.Researchers
2、report the system is able to predict lightning strikes up to 30 minutes before they happen within a 30-kilomcter area. Lightning is a strong burst of electricity in the atmosphere. Since it carries an extremely powerful electrical charge,it can cause very deadly results. European researchers have es
3、timated that between 6,000 and 24,000 people are killed by lightning worldwide each year.For this reason,climate scientists have long sought to develop methods to predict lightning. The system tested in the experiments uses a combination of data from weather stations and machine learning methods. Th
4、e researchers developed a prediction model that was trained to recognize weather conditions that were likely to cause lightning. The model was created with data collected over a 12-year period from 12 Swiss weather stations in cities and mountain areas. The data, related to four main surface conditi
5、ons: air pressure, air temperature, relative humidity(湿度) and wind speed,was placed into a unique machine learning algorithm (算法) , which compared it to records of lightning strikes. Researchers say the algorithm was then able to learn the conditions under which lightning happens. The researchers te
6、st-ran the system several times. They found that the system made predictions that proved correct almost 80 percent of the time. It can now be used anywhere, the Swiss Federal Institute of Technology said in a statement. The researchers plan to keep developing the technology in partnership with a Eur
7、opean effort that aims to create a lightning protection program.The effort is called the European Laser Lightning Rod project. Scientists working on the project are experimenting with a laser technology that could someday control lightning activity, transferring lightning charges from clouds to the
8、ground, They hope that such technology can one day be used as protection against lightning strikes. Possible uses could be at stations, airports or places where large crowds gather. ( )1.Why was the system developed? A.To keep track of lightning deaths. B.To meet peoples curiosity about lightning. C
9、.To protect people from lightning strikes. D.To take advantage of the energy of lightning. ( )2.What is special about the system? A.It collects data samples from around the world. B.It involves the use of a machine learning algorithm. C.It was test-run several times before being put into use. D.Its
10、success owes greatly to a European effort. ( )3.What will the researchers do in the next stage? A.Prevent the formation of lightning. B.Get lightning striking under control. C.Inspire the study of a laser technology. D.Raise the accuracy of lightning prediction. (B) One of the most outspoken support
11、ers that I know of women and girls is actually a man. As co-founder of the ONE Campaign, my friend Bono spends a lot of time speaking out against global poverty. Together, were working to get out a simple, powerful message: poverty is sexist. Women and girls are more likely to be in poverty, less li
12、kely to get an education and more likely to suffer bad health. And when they are born into poverty, it is much more difficult for them to lift themselves and their families out of it. Why? One reason is that breaking out of poverty takes time-and that is a resource women around the world are short o
13、f. On average, women spend about twice as much time as men in doing the unpaid work that makes life possible for everyone, like cooking, washing, cleaning, shopping and caring. In developing countries, the gap is even much bigger. As a result, women have no time to finish their education, learn new
14、skills, open a business develop personal relationships or even go to the doctor. They dream of creating a better future for their children, but they cannot spare the hours to put those dreams that they have into action. The fact that the potential of so many women and girls is going unrealized is a
15、sad thing- but it is also an opportunity for us. We need to recognize, reduce and redistribute the burden of work that is holding them back because if women have time to invest in themselves and their ideas, they could transform the world. ( )4.According to the author, what makes it more difficult f
16、or women to climb out of poverty? A. Sexist prejudice. B. Heavy burden of housework. C. Impossible dreams. D. Bad health. ( )5.The phrase “the gap” in Paragraph 3 most probably refers to the difference in . A.the time women and men spend on their housework B.the space women and men need for their pr
17、ivate life C.the income women and men earn each year D.the dream women and men have about their children ( )6.What seems to be the authors attitude toward reducing female poverty? A. Casual. B. Doubtful. C. Optimistic. D. Unconcerned. ( )7.Which of the following might be the best title for the text?
18、 A. Why poverty is sexist. B. What global poverty is. C. How to reduce female poverty. D. How to break down sexist prejudice. (C) As temperatures drop, leaves begin to turn for us to enjoy glorious autumnal colors. When temperatures rise again in spring, the growing season for trees starts again. Th
19、roughout the warmer months, trees take carbon dioxide from the atmosphere and store it, releasing oxygen as a byproduct. This is the process of photosynthesis (光合作用).The more photosynthesis, the more carbon is locked away. Carbon dioxide is a major driver of climate change, so the more is taken out
20、of the atmosphere by plants, the better. With the warmer climate leading to a longer growing season, some researchers have suggested more carbon dioxide would be absorbed by trees and other plants than in previous times. But a new study has turned this theory on its head. The researchers, led by Deb
21、orah Zani at the Swiss Federal Institute of Technology, studied the degree to which the timing of colour changes in autumn tree leaves was determined by the growth of the plant in spring and summer. Traditionally, temperature and day length were accepted as the main factor determining when leaves ch
22、anged colour and fell, leading some scientists to assume that warming temperatures would delay this process until later in the season. However, in a new study about deciduous (落叶的)European tree species, researchers recorded how much carbon each tree absorbed per season and how that finally affected
23、when the leaves fell. They found that as the rate of photosynthesis increased, leaves changed colour and fell earlier in the year. In a world with increasing levels of carbon in the atmosphere, these new findings imply that warmer weather and longer growing seasons will not allow deciduous trees to
24、take in more carbon dioxide. The studys predictive model suggests that by 2100, when tree growing seasons are expected to be between 22 and 34 days longer, leaves will fall from trees between three and six days earlier than they do now. ( )8. In which column of a newspaper is the passage likely to a
25、ppear? A. Education. B. Economy. C. Nature. D. Tourism. ( )9. The underlined part “turned this theory on its head in Paragraph 2 can be replaced by A. changed the theory completely B. raised questions about this theory C. stressed the significance of the theory D. provided some evidence for the theo
