Most
of Bangladesh is at or below sea level. Rising seawater linked to climate
change has severely affected the country. High water from storms in coastal
areas also adds salt to soil. The land is becoming salty. Crops are less
productive and many areas of cropland in the country are becoming unfit for
farming. These are big problems for the small country. More than 155 million
people live in Bangladesh. Growing crops is the most common way Bangladeshis
support themselves.
To
find a way out，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 (排水).
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.
The
farmers 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.
36．What is mentioned as a big problem for Bangladesh？
A．Severe climate conditions. B．Too many people to support.
C．Lack of enough fresh water. D．Reduced crop productivity.
37．Which mainly makes vegetable growing in vertical gardens successful？
A．Places in the soil for roots. B．Heavy rains kept in the soil.
C．The good soil with little salt. D．Brick pieces added to the soil.
38．What does the underlined word "they" in Paragraph 3 refer to？
A．Bricks. B．Fertilizers. C．Villagers. D．Containers.
39．What can we infer about the vertical tower？
A．It is off the ground.
B．It drains very improperly.
C．It uses bamboo for containers.
D．It is unfit for growing vegetables.

Organic
food is very popular. It is also expensive. Some organic food costs, twice as
much as non-organic food, but new parents and pet owners are willing to pay up
to 200% more for organic food. However, there are people who think it is a
waste of money.
There
is one main difference between organic and non-organic food. Organic farms do
not use agricultural chemicals, such as pesticides. In many countries organic
foods have special labels. These guarantee that the products are natural.
Some
people think organic means locally grown. Originally this was true. Over time
organic farming became more difficult. The demand for organic food grew larger
than the supply. Small companies had to sell out to large companies. There
weren't enough organic ingredients (原料), such as grain and
cattle. This made it difficult for many organic companies to stay in business. Today,
many large companies have an organic line of products.
Is
organic food more nutritious This is part of the debate. Many farmers and
consumers believe it is. They think agricultural chemicals cause health
problems such as cancer. Many health professionals disagree. Few studies prove
that organic foods prevent health problems. Health specialists worry more about
bacteria, such as E. coli and salmonella. These can get into contact with
organic and non-organic food. Doctors recommend washing produce very carefully.
Handling meat carefully is important too.
Most
people agree that naturally grown food tastes better. Is tastier food worth the
extra money This is a matter of opinion. Whether it is healthier or not may
require more research. However, organic consumers argue it is better to be safe
than sorry.
40．What is probably the major concern of organic food consumers？
A．Price. B．Safety. C．Freshness. D．Variety.
41．What is the doctors' suggestion？
A．Grow your own food. B．Reduce the use of pesticides.
C．Make sure the food is clean. D．Buy large companies' products.
42．Which of the following do most people agree on organic food？
A．It tastes better. B．It is easier to grow.
C．It contains more fat. D．It is more nutritious.
43．Where does this text probably come from？
A．A recipe book. B．A chemistry paper.
C．A medical report. D．A health magazine.

【解析】【分析】本文是一篇说明文，“农作物产量减少”是孟加拉国的一个大问题。为了找到出路，这个国家的农民正在学习在所谓的“垂直花园”里种植蔬菜。
【点评】本题考点涉及细节理解，代词指代和推理判断三个题型的考查，是一篇科技类阅读，考生需要准确捕捉细节信息，并根据上下文的逻辑关系，进行分析，推理，从而选出正确答案。
36．考查细节理解。根据第一段中的“Crops are less productive and many areas of cropland in the country are becoming unfit for farming. These are big problems for the small country. ”可知，“农作物产量减少”是孟加拉国的一个大问题。故选D。
37．考查细节理解。根据第二段中的“The soil in these gardens is better because heavy rains have removed much of the salt. ”可知，盐分少的好土让垂直花园的蔬菜种植成功。故选C。
38．考查代词指代。根据第三段中的“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(排水). ”可知，垂直花园很容易建造。村民们用好土和天然肥料装满容器。他们把容器放在砖上，这样它们就离地了。他们在土壤中加入砖块来帮助水流和排水。由此推知划线词they指代的是“容器”。故选D。
39．考查推理判断。根据最后一段中的“The farmers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This 'vertical tower' measures more than a meter wide. ”可知，“vertical tower”其实是更大更宽的containers。再根据第三段“They put the containers on bricks so they are off the ground. ”表明容器是远离地面的，因此推断“vertical tower”同样远离地面。故选A。
