Scientists used to explore(探测)on the surface of the ocean. Now they are exploring below the surface,too. They want to know about ocean water and the plant and animal life deep in the ocean.
In 1934 the scientist William Beebe dived 3000 feet below the surface in a hollow steel ball. In 1935 August Piccard dives 10300 feet. In 1960 his son Jean dived to a depth of 35800 feet.
All these early dives were deep. But the divers could not stay down for very long. They had to come back up to the surface after a few seconds. Scientists needed to stay down longer to study life below surface. Gradually they succeeded. Cousteau,a Frenchman,was able to keep men down to a depth of 26 feet for one month and to a depth of 90 feet for a week.
Now scientists are developing even better equipment. With this new equipment,men can stay below the surface for days or even weeks. In 1962 Cousteau set up a researeh station 35 feet below the surface. Then in l964 he set up another starion on the ocean floor of the Red sea. This was the first undersea station to operate without help from the surface.
Many countries are now studying undersea living. The former Soviet Union has an undersea laboratory in the Crimean Sea. The United Srates has a laboratory 50 feet down on the ocean floor off the Virgm Islands. In 1970 five men lived there for two weeks. Then a team of five women scientists stayed in the laboratory. Next Came other teams of men. All were there to explore the ocean depths and to make plans for the use of its resources. Scientists hope to find enough mineral,vegetable,and animal wealth. there to provide food for the entire world.

The income gap between China's rural and urban residents(居民) has continued to widen during the past few years in spite of rapidly rising rural incomes, Agricultural Minister Sun Zhengcai said here on Wednesday.
The income ratio(比率) between urban and rural residents was 3.28:1 in 2006, against 3.23:1 in 2003, said Sun in his report on the promotion of building a new countryside in 2007. Sun also said the net income of rural residents in different regions also varied widely. The income gap is only one of several problems in rural areas, according to Sun's report. While listing the achievements in rural areas in recent years, Sun believed that rural development still followed behind urban development.
"We have bigger pressure to ensure the supply of major agricultural products such as grain," he said. "China's urbanization(都市化) has been speeded up and more rural residents have gone to urban areas," he said.
"In this case, more agricultural producers become farm produce consumers, which created more pressure for supply," he said.
Another problem facing China's agricultural development is inadequate application of science and technology.
"Only 30 percent of scient ific and technological achievements have been applied to agricultural production, which is 40 percentage points lower than developed countries," he said.
Despite increased government spending in rural areas, the infrastructure(基础下部组织) is still poor and easily hit by disasters.
According to Sun, the government spent 431.8 billion yuan ($59.15 billion) on agriculture, rural areas and farmers this year, an increase of 80.1 billion yuan over the previous year.
China set aside 11.38 billion yuan to promote a new rural cooperative medical care system and 27.98 billion yuan to support the new compulsory education mechanism in rural area to ensure that all citizens shared the fruits of China's reform and opening-up, Sun said.
68．Which of the following is TRUE according to the text?
A．Because of the rapidly rising rural incomes, the income gap between China's rural and urban residents will disappear this year.
B．The net income of rural residents in different regions is the same.
C．The government has taken measures to develop the economy in the rural areas.
D．Beca use of the rapidly rising rural incomes, the supply of major agricultural products is enough.
69．Can you infer the meaning of the underlined words in paragraph 5?
A．be made full use of B．be made little use of
C．be not made full use of D．be made good use of
70． How much is spent on agriculture, rural areas and farmers the previous year?
