I've been writing for most of my life. The book Writing Without Teachers introduced me to one difference and one practice that have greatly helped my writing processes. The difference is between the creative mind and the critical mind. While you need to use both of the creative mind and the critical (批判) mind to reach a finished result，they cannot work in parallel (平行_k.&s~5*u，并行) no matter how much we might like to think so.

　Trying to criticize writing on the fly is possibly the single greatest trouble with writing that most of us meet. If you are listening to a 5th grade English teacher correcting your grammar while you are trying to capture a fleeting（稍纵即_k.&s~5*u逝的）thought, the thought will die. If you catch the fleeting thought and simply share it with the world in raw form, no one is likely to understand. You must learn to create first and then criticize if you want to make writing the tool for thinking as it is.

　The practice that can help you overcome your learned bad habits of trying to edit as you write is what Elbow calls“free writing”. In free writing, the goal is to get words down on paper non-stop，usually for 15-20 minutes. No stopping, no going back, no criticizing. The aim is to get the words flowing. As the words begin to flow，the ideas will come from the shadows and let themselves be captured on your notepad or your screen.

　Now you have raw materials that you can begin to work with using the critical mind that you’ve persuaded to sit on the side and watch quietly. Most likely，you will believe that this will take more time than you actually have and you will end up staring blankly at the pages as the deadline draws near.

　Instead of staring at a blank start and filling it with words no matter how bad they could be，stop halfway through your available time and rework your raw writing into something closer to the finished product. Move back and forth until you run out of time and the final result will most likely be far better than your current practices.

When the author says the creative mind and the critical mind“cannot work in parallel”in the writing process，he means _______.

A. no one can be both creative and critical

B. they can’t be regarded as equally important

C. they are in constant conflict with each other

D. one cannot use them at the same time

What usually prevents people from writing on is _______.

A. putting their ideas in raw form B. attempting to edit as they’re writing

C. ignoring grammatical problems D. trying to capture their fleeting thoughts

What is the chief purpose of the first stage of writing？

A. To organize one’s thoughts logically. B. To choose an appropriate topic.

C. To get one’s ideas down quickly. D. To collect many more raw materials.

In what way does the critical mind help the writer in the writing process？

A. It refines(improves) his writing into a better shape.

B. It helps him to come up with new ideas.

C. It saves the writing time available to him.

D. It allows him to sit on the side and observe.

British scientists are breeding a new generation of rice plants that will be able to grow. in soil con??taining salt water. Their work may enable abandoned farms to become productive farms once more.

Tim Flowers and Tony Yeo, from Sussex University’s School of Biological Sciences,. have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pairs have recently begun a three-year programme, funded by the Biotechnology and Bio??logical Sciences Research Council, to establish which genes enable some plants to survive salty condi??tions. The aim is to breed this capability into crops, starting with rice.

It is estimated that each year more than 10 million hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts(防碍生长) plants. The problem is caused by several factors. In the tropics, mangroves that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation often causes problems when water is evaporated by the heat, leaving, salt deposits behind.

Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive.

To overcome these problems. Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants’ growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resul??ting seeds are ready to be considered for commercial use.

Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food for the poorer countries of the world.

4. Which of the following statements about Flowers and Yeo is true?

A. They are students at Sussex University. B. They are rice breeders.

5. Which of the following is NOT mentioned as a cause of the problem discussed in the passage?

A. Natural barriers to sea water have been destroyed.

B. The water table has gone down after droughts.

C. Sea level has been continuously rising.

D. Evaporation of water leaves salt behind.

6. The word "affect" in Paragraph 5 could be best replaced by________.

A. influence B. effect C. stop D. present

7. The attitude of the author towards the research project is________.

A. positive B. negative C. suspicious D. indifferent
