Reading comprehension of climate in Hainan Island

(1) Hainan Island has a low latitude and gets a lot of solar radiation in winter, so it is warm in winter. The average temperature in Leng Yue (1) is above 16 degrees. Xisha, Zhongsha and Nansha Islands in the south are warmer. Although the winter wind blows to the island, its strength is very weak. Affected by this, the temperature in all parts of the island decreased to varying degrees, and the cooling range decreased from north to south. The cold wave occasionally goes south, and the cooling rate increases, but the duration is not long. Especially due to the blocking of the central mountain, the temperature in the south of the island has not changed much, and the monthly average temperature in Sanya is still above 20 degrees.

(2) In summer, due to the strong solar radiation, the island is generally hot. In the hottest month (July), the average temperature is between 25 and 29 degrees, and the central mountainous area is relatively cool. Due to the influence of summer monsoon and south wind direction from the ocean, there is no heat in most areas in summer. It is also said that it rains continuously in summer and the weather is cool. The extreme maximum temperature is generally higher than 38 degrees, which is already 40 degrees. Records of 3 degrees usually appear in April and May. In June and July, due to the control of subtropical high or the influence of downdraft of typhoon front, there will also be sultry weather. But at other times of the day, except at noon, you can feel the joy and coolness from the wind and the sea.

(3) The annual precipitation in Hainan Island is 1500-2000mm, with abundant rainfall. Except for the semi-humid area in the west, most areas are humid. The precipitation of the whole island is obviously different in rainy season and dry season, wet year and dry year. Precipitation is concentrated in summer and autumn, and the rainfall in April-65438+1October accounts for 80%-90% of the whole year. The precipitation types are mainly convective rain and typhoon rain, and there are many heavy rains and extremely heavy rains with high intensity. But there is less precipitation in winter and spring. The annual precipitation varies greatly, and the wet year is often 2? 3 times, even more than 5 times in southwest China.

(4) There are tropical storms (wind force 8-9), severe tropical storms (wind force10-1level) and typhoons (wind force1level or above) in Hainan Island every year. According to statistics, two storms and typhoons land on Hainan Island every year. Seven times, up to six times a year. In recent years, the impact of wind disasters on Hainan Island has decreased.

17, choose one of the following two small questions to answer. (4 points)

(1) Please summarize the main features of Hainan's climate in concise language according to the above four paragraphs.

A:

A friend of yours is far away in the north. Recently, he called and said that he wanted to travel to Hainan after the senior high school entrance examination this summer, but he heard that it was hot day and night on the island in summer and wanted to back down. Please call him back, explain the actual situation to him, and combine the climate characteristics of Hainan in summer described in paragraph (2) above to mobilize him to travel. You said:

18, what is the central sentence in paragraph (3) that best reflects the characteristics of precipitation in Hainan Island? Please copy the central sentence. ( 1)

A: Yes.

19, a large number of data are cited in the above selections, which shows that what role does this play in expression? (2 points)

A: Yes.

Reference answer:

17, choose one of the two questions.

(1) There is no severe cold in winter, no intense heat in summer, abundant precipitation and frequent wind disasters. Or: it's warm in winter and hot in summer, with more precipitation and more wind disasters. Or: a tropical monsoon climate with high temperature and rain.

This question is 4 points. In addition to the tropical monsoon climate, other answers should have four elements (one element in each paragraph): winter, summer, water and wind. The interpretation of each element is 1.

(2) For example, the summer temperature in Hainan is high and the solar radiation is strong. However, due to the influence of summer monsoon, most areas are not very hot, and because it is cloudy and rainy in summer, the weather is still cool, so the central mountainous areas are even cooler. Although it is very hot outside at noon, the sea breeze blows in the morning and evening, taking away the heat, and the day is still cool and pleasant. My friend, welcome to Hainan in summer!

This question is 4 points. According to the difference of language expression and reasoning, the scores are 4, 3, 2, 1, 0 respectively.

18, the precipitation of the whole island is obviously different in rainy season and dry season, wet year and dry year.

Account 1. A: If there is abundant rainfall, you will get 1 point.

19, enumerating figures makes the explanation more accurate and specific, enhances the scientific nature of the explanation and makes people more credible.

This question is 2 points. One of the accurate and scientific keywords will get 2 points.
