问题 材料分析题

阅读图文资料,完成下列各题。

葡萄的糖分含量越高,酿制出的葡萄酒酒精度越高。葡萄生长过程中,特别是成熟的光照及昼夜温差与其糖分积累呈正相关。图a中甲、乙两地均为优质葡萄产地。图b为乙地典型的葡萄种植园景观。世界上酒精度最高(16.2度)的优质葡萄酒就是使用乙地及其附近所产的葡萄酿制而成的。

(1)分析甲地有利于种植葡萄的地形、气候条件。

________________________________________________________________________________________________________________________________________________________________

(2)分析乙地葡萄种植园地表鹅卵石堆积的原因。

________________________________________________________________________________________________________________________________________________________________

(3)简述乙地气候类型和特点,并说明气候条件以及葡萄种植园地表鹅卵石对葡萄生长的影响。

________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

答案

(1)甲地位于(南北向的)河谷中,灌溉(和排水)条件好;(北纬45°附近)葡萄生长季节日照时间长,光照充足;葡萄成熟季节昼夜温差大,利于糖分积累。

(2)乙地位于(罗讷河)河流出山口附近。河流出山口前,穿行于峡谷,水流急,可携带砾石;河流出山口后,流速变缓,携带的砾石首先在此处堆积。

(3)乙地(临地中海)为地中海气候;冬季温和多雨,夏季炎热干燥。葡萄生长季节光照、热量充足。鹅卵石利于保持土壤水分(利于地表水下渗,防止土壤水分蒸发);鹅卵石白天(受到太阳辐射)增温快,夜间降温也快,增大气温的日较差,利于葡萄的糖分积累。

A desert is a very dry land where there is hardly any rain. In the day, it can be so hot that you could fry an egg on the ground. But during the night it is sometimes so could that water would turn into ice.

Many desserts are covered in sand. But some have mountains, rocks, or lakes that have dried up in the heat. The Great American Dessert has cliffs(悬崖) that have been made into amazing and beautiful shapes by the wind. The Sahara Desert in Africa is mostly sand. The Australian Desert has red sand.

Sometimes it does not rain for a whole year in the desert. But there is water deep under the ground and some plants have roots that go very deep to find it. Other plants have roots that spread out(延伸) a long way so they can suck up the rain as soon as it falls.

One desert plant is the cactus, which has long, spreading roots. The cactus stores water inside its hard skin. This skin protects it from heat and cold.

Camels are a bit like cactus plants! They store water too—inside their bodies. They have special fur which protects them from the sun during the day and keeps them warm at night.

Some other animals live in deserts, too. They have to be very good at seeing and hearing because most of them only come out at night. This is why many desert animals have extra big eyes or ears.

A desert fox has bigger ears than a normal for. A gerbil has huge eye, so that it can see at night. It stays cool in the day by staying underground, like most desert animals.

Some people live in the desert but they always make their homes near an oasis. An oasis is where water comes from an underground river. Near an oasis, people can grow lots of plants and keep animals.

Life is hard in the desert, for people, animals and plants. But desert people like to live there.
