【题目】
【1】关于东北地区地理环境的叙述，不正确的是
A．东北地区包括黑龙江、吉林、辽宁三省
B．山环水绕、沃野千里是东北地区自然环境的基本特征
C．东北地区自南向北跨暖温带、中温带、寒温带
D．东北地区的降水量自东南向西北递减
【2】东北平原今后农业发展的方向应该是
A．尽快开发未垦荒地，扩大粮食播种面积
B．大规模退耕还湿地，停止粮食生产，建立自然保护区
C．全面退耕还渔，变种植业主导产业为水产业主导产业
D．推进农业向规模化、专业化和生态化方向发展，建设绿色食品基地
【答案】
【1】B
【2】D
【解析】
试题分析：
【1】东北地区还包括内蒙古东部，A项错误。东北地区自南向北跨暖温带、中温带、寒温带，降水量自东南向西北降水呈减少趋势，南北差异大，故C、D项错误。东北地区西有大兴安岭、北有小兴安岭和黑龙江、东有长白山地和乌苏里江、图们江、鸭绿江等具有山环水绕的特征，松嫩平原、三江平原黑土分布广，具有沃野千里的特征。故B项正确。
【2】本题考查农业可持续发展的途径。循环经济以环境无害化技术为手段，以提高生态效益为核心，以环境友好方式利用经济资源和环境资源，实现经济活动的生态化。循环经济在农业中主要表现为生态农业。生态农业将农业生产和生态平衡纳入协调一致的轨道。它模拟自然生态系统的结构和功能，形成经济上和生态上的良性发展。所以本题选择D选项。

Researchers in China and the United States have developed a new cataract(白内障)treatment with cells that has restored vision in babies in a trial and may eventually be used in adults.
The treatment- by doctors and staff members at the University of California, San Diego School of Medicine and Sichuan and Sun Yat-sen universities in China-was published in March 9 edition of the scientific journal Nature.
A cataract is a clouding of the normally clear lens(晶体)of an eye. Typical cataract operation involves the removal of the cloudy lens and the insertion of an artificial one. The new operation has been tested in animals and during a small, human trial. It resulted in fewer complications(并发症)than the current harmful operation, and in regrown lenses with superior visual function in all 12 of the baby cataract patients who received the procedure.
A congenital cataract- lens clouding that occurs at birth or shortly after- is important cause of blindness in children. In the new research, Kand Zhang, head of ophthalmic genetics at US San Diego’s Shiley Eye Institute, and his colleagues relied on the regrown potential of endogenous(同源的)stem cells.
According to Zhang, endogenous stem cells are different from other stem cells that are typically grown in a laboratory, transplanted into a patient, and can have risks of immune（免疫的）rejection, infection or cancers. Zhang told CBS News, “We invented a new operation to make a very small opening at the side of a cataractous lens bag, remove the cataract inside, allow the opening to heal, and promote potential lens stem cells to regrow an entirely new lens with vision.”
The human trial involved 12 babies under the age of 2 who were treated with the new method, while 25 babies received thee standard operation care.. The latter group experienced a higher incidence of pos- operation danger, early- onset eye high blood pressure and increased lens clouding. The scientists reported fewer complications and faster healing among the 12 babies who has the new procedure.
【1】What is the text mainly about?
A. The concept of the cataract
B. A new cataract treatment with stem cells
C. Bad effects of post-operation in the cataract
D. The reasons why the cataract comes into being
【2】Which of the following best describe the new cataract treatment according to the passage?
A. Convenient B. Comfortable C. Cheap D. Safe
【3】What can we learn about the new cataract treatment?
A. It has more risks
B. It may be used widely
C. It has been put into practice widely
D. It can only restore vision in babies
【4】What does the underlined word “congenital” in the fourth paragraph mean?
A. Born B. Strange C. Serious D. Dangerous.

A garden that’s just right for you
Have you ever visited a garden that seemed just right for you, where the atmosphere of the garden appeared to total more than the sum(总和) of its parts? 1 . But it doesn’t happen by accident. It starts with looking inside yourself and understanding who you are with respect to the natural world and how you approach the gardening process.
● 2
Some people may think that a garden is no more than plants, flowers, patterns and masses of color. Others are concerned about using gardening methods that require less water and fewer fertilizers(肥料). 3 . However, there are a number of other reasons that might explain why you want to garden. One of them comes from our earliest years.

Grandma’s rose garden and Dad’s vegetable garden might be good or bad, but that’s not what’s important. 4 —how being in those gardens made us feel. If you’d like to build a powerful bond with your garden, start by taking some time to recall the gardens of your youth. 5 then go outside and work out a plan to translate your childhood memories into your grown-up garden. Have fun.

Five secrets to living a sunshine life
Don’t avoid or ignore negativity.
In order to conquer and overcome the negativity, it must be acknowledged. You are in control of your environment and if these negative situations keep making an appearance, it’s up to you to handle them.
Take care of yourself and your needs.
In order to live a powerful and meaningful life, you must love yourself. 1 And this will be reflected in your thoughts and emotional state of mind. Love yourself fully in order to love others fully.
2
Determine what is worth your time and effort and what is not. If situations are bad and beyond repair, it’s time to let go. Are there relationships or friendships that remain damaged but you know are worth the time? 3 Do what you can to find love in situations where it may have been absent in the past.
Give.
Give our time, energy, love and sometimes money to others. 4 So if you can, don’t hesitate to do it.
Focus on things that make us smile, laugh and feel good.
This one is pretty simple. 5 That is, do more of what makes you happy! I truly believe happiness may not come as easily as we wish. In order to go through work and boring responsibilities, we have to actively pursue and engage in beautiful acts of love and kindness. So let’s have a try.
