【题目】B
Many areas of cropland in Bangladesh(孟加拉国) are becoming unfit for farming. The land is becoming salty. It is a big problem for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.
Farmers in the country are learning to grow vegetables in so-called "vertical gardens." The soil in these gardens is better because heavy rains have removed much of the salt.
A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain.
The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.
Villagers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This "vertical tower" measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12-$13 to build.
The village of Chandipur is in southwestern Bangladesh. Pumpkins and other gourds(葫芦) grow on vines on top of small homes. The vegetables get the food they need from soil placed in containers on the ground.
Shobitha Debna is a 35-year-old farmer in the village. Her garden space is very small. But she is able to grow hundreds of kilograms of vegetables each season.
She says she grows gourds, including pumpkin, as well as green beans, red amaranth, beets, carrots, cauliflower and more.
Ms. Debna depends on the vegetables to earn money. She makes a few dollars a day.
This kind of farming is new in Chandipur. But it may spread across the country.

B. more and more land is used for planting trees
C. the land is becoming salty
D. there is too much rain
【2】Why the soil in vertical gardens is better_______?
A. because there is much less salt in the soil
B. because there is much salt in the soil
C. because there is enough water in the soil
D. because there is many nutrients in the soil
【3】From paragraph 4, we can learn that_______?
A. vegetables with long roots grow in the sides of the containers
B. vegetables with short roots grow out of the small holes in the sides of the containers
C. vegetables with short roots grow on top of the container
D. vegetables in vertical gardens are not productive
【4】Ms. Debna grows many kinds of vegetables EXCEPT________.

【解析】文章主要讲的是孟加拉国农民使用创新方法来种植农作物。孟加拉国的许多耕地正在变得不适合耕种，耕地的盐碱化很严重。孟加拉国人正在使用一种叫做“垂直花园”的方法来种植农作物。
【1】C 细节理解题。根据第一段“The land is becoming salty.”可知，孟加拉国的耕地盐碱华严重，越来越多的土地正在变得不适合耕种。
【2】A 细节理解题。根据第二段“The soil in these gardens is better because heavy rains have removed much of the salt.”可知，大雨冲走了垂直花园里的土壤中的盐分。
【3】B 推理判断题。根据第四段“small holes into the sides of the containers. This permits vegetables with short roots a place to grow.”可知，村民在容器的侧面开一些小洞，这样有利于短根蔬菜生长。
【4】D 细节理解题。根据“she grows gourds, including pumpkin, as well as green beans, red amaranth, beets, carrots, cauliflower and more.”可知，Ms. Debna种的有葫芦、南瓜、红苋菜、甜菜、胡萝卜和花菜等，文中没有提到黄瓜。
【5】C 推理判断题。根据最后一段“This kind of farming...may spread across the country.”可知，这种新型的种植方式有可能在孟加拉国全国范围内得到推广。A项是文中的原话，不是推理出来的结论。
