Ⅰ.阅读理解
Three experimental fields of seawater rice were harvested in China on Wednesday, a further step toward its future practical use.Also known as saline alkali tolerant rice (耐盐碱水稻), the seawater rice is designed to grow in seaside flats or other areas with high salt content and has been developed by experts through crossbreeding (杂交) and other technologies.
One type of seawater rice growing in Qingdao's Chengyang district, Shandong Province，produced 3.9 metric tons (公吨) per hectare (公顷), experts announced.Once widely planted in large areas, the output could be much higher.
The Qingdao Saline Alkali Tolerant Rice Research and Development Center, led by renowned Chinese agricultural scientist Yuan Longping, was established several years ago.It set itself a three year target of developing a kind of salt resistant rice capable of producing 4.5 tons a hectare, which would guarantee growers the minimum acceptable level of profit.The average rice output in China is 6.75 tons a hectare.
Planting in the experimental field in Chengyang district and five other plots of saline alkali land started at the end of May.The five other plots were in Dongying, Shandong Province；Wenzhou, Zhejiang Province；Yan'an, Shaanxi Province；Kashgar, the Xinjiang Uygur Autonomous Region；and Daqing, Heilongjiang Province.The sites represent actually every type of saline alkali land in China and researchers aim to grow different kinds of rice able to cope with different climate, salinity and soil structure conditions.
The test crops in Kashgar and Daqing were also harvested on Wednesday.In Kashgar, the output reached more than 7.5 tons per hectare, according to experts' tests, much higher than expected.The harvest in Kashgar was satisfactory.The result means it is possible to plant such salt resistant rice in southern Xinjiang in the future.Xinjiang has about 2 million hectares of saline alkali land that have the potential to be planted with salt resistant rice, and if it is widely planted it will generally improve rice production in the region.
The seawater rice grown in Daqing only produced 3.1 tons per hectare.A live video on Shandong TV showed growers appearing a little disappointed by the result, as they hoped the experts' efforts would increase production greatly.The water and soil conditions of the site were not ideal, and the PH level was extremely high.
语篇解读：本文是一篇说明文。文章主要介绍了在中国的三块试验田的“海水稻”喜获丰收，这是其在未来的实际应用中又前进了一步。
1．Which is the main feature of seawater rice according to the text
A．It has a shorter growing period.
B．It is a kind of highly productive crop.
C．It can grow in the soil with high salt content.
D．It is the combination of many technologies.
解析：选C 细节理解题。根据第一段中的the seawater rice is designed to grow in seaside flats or other areas with high salt content可知，海水稻的主要特点是可以种植在含盐量高的土壤里。
2．How much rice does a farmer harvest at least to meet the cost
A．3.9 tons a hectare.
B．4.5 tons a hectare.
C．6.75 tons a hectare.
D．7.5 tons a hectare.
解析：选B 细节理解题。根据第三段中的producing 4.5 tons a hectare, which would guarantee growers the minimum acceptable level of profit可知，每公顷4.5吨的产量对种植者来说是最低的收益保障。
3．The researchers chose the experimental fields according to ．
A．the distance between them
B．the type of the soil and climate
C．the local governments' support
D．the local agricultural conditions
解析：选B 细节理解题。根据第四段最后一句可知，研究人员选择试验田的依据是气候、土壤的盐度和土壤结构。
4．What can we infer about the seawater rice from the last paragraph
A．The seawater rice is not fit for all kinds of saline alkali soils.
B．It is impossible for the seawater rice to have a good harvest.
C．Growers from Shandong Province were a little disappointed by the result.
D．The output of the seawater rice grown in Daqing is the lowest.
解析：选A 推理判断题。根据最后一段最后一句可知，海水稻并非适合所有的盐碱地。

Ⅲ.概要写作
阅读下面材料，根据其内容写一篇60词左右的内容概要。
Most people expose themselves to swimming situations according to their levels of skill and comfort.The same might be true as you assess your comfort level with different academic environments in search of a good college which fits you best.Just as you might figure out the temperature and depth of the water before venturing in, before you apply, you need to investigate the academic environment of a college and your ability to “keep your head above water” if admitted.
When looking at academic rigor (严谨) as an indication of “fit”， you are likely to find that you have the capacity to “get the job done” academically in a range of college environments.In other words, you are not likely to have difficulty with the “water” itself.You will fit best, however, at colleges and universities where your ability and preparation enable you to rise to new levels of challenge.Your goal should be to find academic environments where your levels of ability and preparation will enable you to achieve well as you stretch yourself intellectually.
The best sources of insight regarding your preparedness to meet the academic standards of various colleges and universities are your high school teachers, because they are familiar with your capabilities, and they can offer invaluable advice about identifying the colleges where you will find the best academic programs for you.
Assuming you are able to find appropriate academic environments, then you should be smart about choosing where to apply.Choose colleges and universities where you can be most competitive based on your skills and preparation.Whether you compete in the pool or on the stage or in the classroom, you have the best chance of finding success when your skills prove your capacity to do the work and you are competitive with those around you.Put yourself into competition at universities where you fit best and enjoy the success that is bound to come your way as a candidate.
参考范文：
Like finding a comfortable environment to swim, choosing a college with suitable academic environment is very important for students.(要点1) Students' goal should be finding academic environments to which they can adapt as well as challenging themselves.(要点2) Seeking advice from high school teachers is a good idea as they know their students well.(要点3) After finding out the environments, students should apply to universities at which they are competitive and can achieve success.(要点4)
