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.

(1)、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.
(2)、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.
(3)、What does the underlined word "they" in Paragraph 3 refer to?
A、Bricks. B、Fertilizers. C、Villagers. D、Containers.
(4)、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.

    A new argument has been put forward as to whether penguins are disturbed by the presence of tourists in Antarctica.

    Previous research by scientists from Keil University in Germany monitored Adelie penguins and noted that the birds' heart rates increased dramatically at the sight of a human as far as 30 meters away. But new research using an artificial egg, which is equipped to measure heart rates, disputes this. Scientists from the Scott Polar Research Institute at Cambridge say that a slow moving human who does not approach the nest too closely, is not viewed as a threat by penguins.

    The earlier findings have been used to partly explain the 20 per cent drop in populations of certain types of penguins near tourist sites. However, tour operators have continued to insist that their activities do not adversely(不利地)affect wildlife in Antarctica, saying they encourage non-destructive behavior in tourists, and that the decline in penguin numbers is caused by other factors.

    Amanda Nimon of the Scott Polar Research Institute spent three southern hemisphere summers at Cuverville Island in Antarctica studying penguin behavior towards humans. “A nesting penguin will react very differently to a person rapidly and closely approaching the nest,” says Nimon. “First they exhibit large and prolonged heart rate changes and then they often flee the nest leaving it open for predators(掠夺者)to fly in and remove eggs or chicks.” The artificial egg, specially for the project, monitored both the parent who had been 'disturbed' when the egg was placed in the nest and the other parent as they both took it in turns to guard the nest.

    However, Boris Culik, who monitored the Adelie penguins, believes that Nimon's findings do not prove his own research invalid. He points out that species behave differently – and Nimon's work was with Gentoo penguins. Nimon and her colleagues believe that Culik's research was methodologically(方法论上)defective because the monitoring of penguins' responses needed catching the birds and fitting them with heart-rate transmitters(发射器). Therefore, argues Nimon, it would not be surprising if they became stressed on seeing a human subsequently.

Three Feet From Gold

    Darby's uncle was caught by the "gold fever" in the gold—rush days, and went west to dig and grow rich. After months of labor, he was rewarded by the discovery of the shining ore (矿石). He needed machinery to bring the ore to the surface. So, with the "strike", he returned home. And with the help of Darby, he borrowed a lot of money. After buying the machinery and having it shipped, Uncle and Darby went back to work the mine.

    The first car of ore was mined. And the returns proved they had one of the richest mines in Colorado! Down went the drills! Up went the hopes of Uncle and Darby!

    Then something happened! The vein (矿脉) of gold ore disappeared! They drilled on, but all in vain. Finally, they decided to quit and sold the machinery to a junk man for a few hundred dollars. The junk man called in a mining engineer to look at the mine and do a little calculating. The engineer's calculations showed that the vein would be found just three feet from where the Darbys had stopped drilling! The junk man took millions of dollars in the vein, because he knew enough to seek experts' advice before giving up.

    Most of the money which went into the machinery was borrowed through the efforts of Darby, who was then a very young man. The money came from his relatives because of their faith in him. He paid back every dollar of it, although he was years in doing so.

    Long afterwards, Mr. Darby made another discovery that desire can be changed into gold. This discovery came after he went into the business of selling life insurance. Remembering that he lost a huge fortune, for he stopped three feet from gold, Darby profited by the experience in his chosen work, saying to himself, "I stopped three feet from gold, but I never stop because men say 'no' when I ask them to buy insurance."

    Darby sold more than million dollars in life insurance annually. He owes his "stick-ability" to the lesson he learned from his "quit-ability" in the gold mining business.
