Ask the geography master to answer, and the master will answer the geography question

1) Lhasa is located on the Qinghai-Tibet Plateau, with low latitude, high terrain, thin air, large daily temperature difference, strong solar radiation during the day, which promotes warming, and weak atmospheric inverse radiation at night, which promotes cooling. The annual range is small, in summer, the high altitude makes the temperature low, and in the winter, the low latitude makes the sun not low. So the answer is c.

2) I is Lhasa, because Lhasa has the most sunshine in autumn, and in summer, because of rainfall, the sunshine is less than in spring, autumn and winter.

Sunshine City, "Lhasa's Sunshine Hours"; It is also easier to judge that Chongqing is located in the Sichuan Basin, which has many rainy days and little sunshine. So the answer is c.

3) The temperature is judged to be the highest in Hainan, so Hainan is, Chongqing is impossible to be below zero, so it is Chongqing, it is Lhasa that has been judged, the largest annual temperature difference is Urumqi, and the sunshine hours Lhasa Hainan Urumqi Chongqing, so the answer is d.

5 c 6 c 7 d

5. Lhasa is located on the Qinghai-Tibet Plateau, due to the high terrain, thin air, weak atmospheric weakening and thermal insulation, small annual difference, low temperature in summer, reading the map to judge that it is in line with C.

6. Lhasa is a city of sunshine, with large sunshine hours but low latitude; In the summer, the more north the day is longer, Urumqi is higher than Lhasa, deep inland, sunny days, sunshine is strong, so it is Urumqi, Lhasa, Chongqing (located in the Sichuan Basin cloudy and rainy days, less sunshine), choose C.

7. Mobilize existing knowledge to judge in combination with the map: the temperature Hainan Chongqing Lhasa Urumqi, the sunshine hours Lhasa, Hainan Urumqi Chongqing, so the correct combination is 4

Your answer to question 17 is wrong, the answer should be A.

Analysis: The shortest shadow of a day in a certain place is 12 noon locally. Therefore, according to 1 p.m. Beijing time, it is 12 o'clock in the place, and the time is judged to be one hour later than Beijing time.

Because it is our country, north of the Tropic of Cancer, the sun is due south when it is 12 o'clock in a certain place.

When Beijing time is 15 o'clock and local time is 14 o'clock, the angle of the sun's deviation from due south is about (14 12) 15°=30°, so the angle of the sun from due south is about 30°; and the sun rises in the east and sets in the west; At 14 o'clock the Sun should be located due south and west, so Figure A is correct. If it's c, you can see that the sun is east of due south.

18 questions, using the sun to identify the direction, the main principle is to use the sun at noon due south or north, and then according to the specific time of the sun position and the angle difference between the sun at noon due south to determine the direction. Therefore, it is important to be able to find whether the sun is due south or north at noon, 1 and 3 are well determined, 1 is the sun is due south at noon all year round, and 3 is due north at noon. 4 Near the equator, if there is direct sunlight, at noon, the sun is neither due south nor due north.

So it is impossible to judge the direction. 3 Situation, near the equator, the sun is due east at sunrise at sunrise and the sun is due west at sunset. For other dates, the offset is not large.

Sentence-by-sentence analysis.

17 The first sentence is about an hour away from Beijing.

In the second sentence, three o'clock is actually two o'clock in the place.

The rest can watch episode 76 of "Conan".

18. Since the sun goes back and forth between the north and south lines, it is impossible to judge (1), (2), (4) or wrong when it is shining directly.

3) When not direct shooting.

It is recommended that if there are five or three, you can take a good look.

17.At 13 o'clock Beijing time, 12 o'clock local time, the sun is located in the southward direction at noon, at 15 o'clock in Beijing time, and at 14 o'clock local time, the angle of the sun deviating from the southward direction is about (14 12) 15°=30°, so the angle of the sun from the southward direction is about 30°; and the sun rises in the east and sets in the west; At 14 o'clock the Sun should be located due south and west, so Figure C is correct.

18.Suitable for mid to high latitudes, when the sun is close to the east or west at 6 o'clock at sunrise or 6 o'clock at sunset.

Analysis] Plastic film will cause white pollution, harm crop roots, and have the effect of "heat preservation, moisturizing, and soil retention", which will hinder the migration of soil moisture. It is conducive to the increase of soil temperature and water retention.

Analysis] The easterly isotherm in the central part is densely distributed and closed, and is located in the Taiwan Mountains, so the main factor affecting the annual average temperature distribution in this region is topography.

Analysis】 The terrain is flat, located on the leeward slope of the summer monsoon in the Taiwan Mountains, and the annual precipitation is relatively low.

Analysis] Camphor trees are suitable for distribution in slopes and valleys with low altitude, gentle slope and good light conditions.

Analysis] When the cold current of California passes through the warm sea near California at the middle and low latitudes, the temperature decreases and the water vapor condenses to form sea fog.

Analysis] The strong wind is conducive to the dissipation of fog, and the Mediterranean climate zone is controlled by the subtropical high in summer, and the wind is small. In winter, it is controlled by the prevailing westerly winds and the winds are stronger.

Analysis] S City (San Francisco) has a Mediterranean climate, which is mainly controlled by the subtropical high in summer.

12. A Analysis] This question takes the fiscal policy implemented in China as the background, and takes the moderate fiscal deficit as the starting point to test students' understanding of the active fiscal policy. Fiscal deficit means that the country's fiscal expenditure is greater than fiscal revenue, and the state expands fiscal expenditure to form aggregate social demand in the market, thereby promoting economic growth and stimulating production. The reduction in the tax burden in item B is not the result of the fiscal deficit and is therefore excluded; Item c is not related to the topic and is discarded; Item D is incorrect, increasing the total social supply is to expand fiscal revenue, which is also inconsistent with the question, so the correct answer to this question is A

13、d。From the key information that "many network companies have also invested heavily in the research and development of smart phones, and the smart phones with built-in network products are introduced to the market", it can be seen that the purpose of network companies to produce mobile phones is to extend their industrial chain and improve their comprehensive competitiveness. Item A is absolute, the profit margin of the production of smartphones is not necessarily higher than that of other industries; Items b and c are not reflected in the material.

Question 7 chooses a because the shadow of the flagpole only faces due east or west, which means that the sun rises due east and sets in the east on that day, which can only be the spring and autumn equinox, because if the sun shines directly on the northern hemisphere, the global sun rises northeast and sets northwest (except for the polar day and night), the sun shines directly on the southern hemisphere, and the global sun rises southeast and sets southwest, and the situation in the figure can only be direct to the equator. The noon shadow length of the place is 0, indicating that the place is on the equator. The longest shadows in a place during the day should be at sunrise and sunset, when the sun is at its most oblique.

Therefore, the place is sunrise at 7:20 Beijing time, and the equatorial sunrise time is 6 o'clock local time throughout the year, according to which it can be calculated that the place is 20° west of 120°E longitude, which is 100°E. To sum up, choose A.

Question 8 Option C According to the above question, the symmetry point of the ground should be 0°, 80°W, and the only one that meets this requirement is C, the Amazon estuary is near the equator, but the longitude is about 50°W.

Question 9 Option d There is no geostrophic deflection force at the equator, so no cyclone can be generated. Equatorial rainfall is basically convective rain.
