Passage 1
California has been facing droughts for many years, with certain areas even having to pump freshwater hundreds of miles to their distribution system. The problem is growing as the population of the state continues to expand. New rearch has found deep water rerves under the state which could help solve their drought crisis. Previous drilling of wells could only reach depths of 1,000 feet, but due to new pumping practices, water deeper than this can now be extracted (抽取). The team at Stanford investigated the aquifers (地下蓄水层) below this depth and found that rerves may be three times what was previously thought.
It is profitable to drill to depths more than 1,000 feet for oil and gas, but only recently in California has it become profitable to pump water from this depth. The aquifers range from 1,000 to 3,000 feet below the ground, which means that pumping will be expensive and there are other concerns. The biggest concern is the gradual tting down of the land surfa
ce. As the water is pumped out, the vacant space left is presd by the weight of the earth above.
Even though pumping from the depths is expensive, it is still cheaper than desalinating (脱盐) the ocean water in the largely coastal state. Some desalination plants exist where possible, but they are costly to run and can need constant repairs. Wells are much more reliable sources of freshwater, and California is hoping that the deep wells may be the answer to their vere water shortage.
One problem with the sources is that the deep water also has a higher level of salt than shallower aquifers. This means that some water may even need to be desalinated after extraction, thus increasing the cost. Rearch from the study of groundwater has just been published. New estimates of the water rerves now go up to 2,700 billion cubic meters of freshwater.

Passage 2
What will the future school look like is difficult to make clear, but most experts(专家) agree that the school will be electronic in the future.
春节作文英语“Prent-day schools will no longer exist in the next century,” says a report in The Age. “At that time, future schools will become community-style centers, which run ven days a week, 24 hours a day.” At the same time, computers will surely become a central part of the school in the future.
According to The Age, the distant learning will be popular and students will listen to teachers on computers. Going into classrooms on their computers, students will study at
any time, which is very easy for them. However, it is necessary for students to go to the actual school in order to develop some social skills.
The Seashore Primary School is an imaginary school in the future created by the Education Department of Australia. At this school, all the teachers and students have laptop computers. Teachers check messages and call students back on a special telephone system and students u telephones to arch for information or speak to their experts who teach their lessons. Besides, all the lessons are related to all sorts of subjects and all the students have their own learning plans created by teachers.
As one headmaster says, a laptop computer is students' library, data storage(数据存储)as well as the bridge to a wider world. Technology has changed the emphasis of future learning. Thus, we'll pay more attention to the learning of kids rather than the teaching.
1. According to the report in The Age, students in future schools will.
A. mainly study online B. study at a t time
玩具房C. have no teachers D. never go to actual school
嗜书如命的意思2. The example of the Seashore Primary School is given to show.

A. telephones are important in Australia
B. how future schools will work
C. every student needs a learning plan
D. students enjoy getting in touch with teachers
3. What does the underlined word “emphasis” in the last paragraph mean?
