　　2014年高考英语考试已经结束，新一轮的高考复习又将开始。面临2015年高考，考生应该如何复习高考英语这个考试科目呢?新东方在线高考网汇总整理《高三英语知识点：复习题阅读理解篇10》，供2015年高考考生参考。

　　Japanese doctors have used thin sheets of tissue from people’s cheeks to repair damaged corneas(角膜). A team from Osaka University transplanted thin layers of cheek cells onto the eyes of four patients with a rare and painful eye condition, reports BBC online. Patients whose vision had been cloudy could see well afterwards, and the “new corneas” remained clear more than a year after the operation.

　　Doctors can also take cells from a healthy eye and grow them in a dish to produce a new cornea, or they can transplant corneas from donors. But these techniques may not work when both eyes are too badly damaged by accident or disease.

　　The team hope their work may help solve the problem and lead to other types of grow-your-own tissue transplants. The cornea is the clear layer of cells on the surface of the eye. It can be damaged by trauma(外伤) or by a range of diseases.

　　The team worked with four patients who had a painful condition that caused cloudy corneas and dry eyes. Often the eye can regenerate cornea cells but none of the four patients had this ability. The researchers took a 3 mm-wide square of tissue from inside the mouth(cheeks) and grew it into q thin layer in the lab. They used a special low-temperature technique to separate a very think sheet off each batch(组). They then laid that onto the patient’s eye. The cell layers stuck onto the eye and developed into tissue that looked and acted like a healthy cornea.

　　However, long-term follow-up and experience with a large series of patients are needed to assess the benefits and risks of this method. “Yet, it does offer the potential of treating severe eye diseases that are resistant to standard approaches,” said the head of the research, Kohji Nishida.
