河南专升本专业英语真题
Do you always forget things? A new research suggests you might need more outdoor activity and exposure to sunlight to improve your memory. Scientists at the University of Science and Technology of China found that moderate LTV exposure enhances learning and memory by promoting a novel glutamate (俗氨酸盐)bio-synthetic pathway in the brain. The discovery was recently published in the academic journal, Cell.
Xiong Wei, lead scientist of the research, said moderate exposure to the sun has many benefits, including promoting the synthesis of Vitamin D and treatment of many skin diseases.
Scientists also found that sunlight will affect the neural system. Moderate exposure might help lift your spirits and improve cognitive functions. However, the deep-level mechanism between sunshine and the neural system is still unclear.
Combining research methods in cell biology and neuroscience, researchers discovered that being exposed to the sun might greatly increase the content of a chemical substance called UCA in the blood of animals. UCA enters nerve cells in the brain, and transforms into glutamic acid by a series of bio-metabolic enzymes. The glutamic acid is released in the nerve endings of the motor cortex and hippocampus, a brain region vital to memory and learning, said Xiong Wei.
The research will play an important role in understanding the working mechanism of the brain and pathogenesis of relevant diseases.
1.What is the passage mainly about?
A.The ways to improve your memory.
B.The advantages of moderate UV exposure.
C.The reason why people always forget things.
D.The mechanism between sunshine and the neural system.
2.which of the following is NOT the benefit of moderate exposure to the sun?
A.Helping lift your spirits.
B.Treating all skin diseases.
C.Improving cognitive functions.
D.Promoting the synthesis of Vitamin D.
3.We can know from the passage that 4tthe motor cortex and hippocampus” (Para. 4) is______.
A. nerve cells
B. the neural system
C. a chemical substance
D. a portion of our brain
4.Which of the following statements about UCA is RIGHT according to the passage?
A.We can't find UCA in the blood of human beings.
B.Being exposed to the sun might greatly decrease UCA.
C. CA is a kind of chemical substance in the blood of animals.
D. UCA enters nerve cells in the blood, and transforms into glutamic acid.
5. What can we learn from the recent research?
A.Outdoor activities can enhance one’s learning and memory.
B.The mechanism between sunshine and the neural system is clear to us.
C.The research will help us understand the working mechanism of the brain
D.The motor cortex and hippocampus is not important to memory and learning
参考答案
1. 【考点】主旨大意题。
【精析】B 文章第一段为背景+观点的写作手法，观点：moderate LTV exposure enhances learning and memory by promoting a novel glutamate (俗氨酸盐)bio-synthetic pathway in the brain.即为文章主旨句，可得出答案选 B。
2. 【考点】事实细节题。
【精析】 B 从 oderate exposure to the sun has many benefits, including promoting the synthesis of Vitamin D and treatment of many skin diseases 得出，适当晒太阳可以治疗“很多”皮肤病，并不是所有，所以答案选 B。
3. 【考点】词义猜测题。
【精析】D 从 The glutamic acid is released in the nerve endings of the motor cortex and hippocampus, a brain region vital to memory and learning, said Xiong Wei.可看出所猜词后的插入语是对前面关键词的解释说明 a brain region vital to memory and learning,是对于记忆和学习非常重要的一个区域，所以得出答案运动皮层和海马体是大脑的一部分。
4. 【考点】事实细节题。
【精析】 C 从 being exposed to the sun might greatly increase the content of a chemical substance called UCA in the blood of animals. 得出 C 是正确的。A 属于无中生有，B 应该是增加，D 应该是大脑不是血液。
5. 【考点】推理判断。
【精析】C 从最后一段可得出 C 是可以推断出来的，A 应该是适当的暴露在紫外线之下，并不是户外活动可以。B 无中生有，文中没有说。D 正话反说，应该是重要的。
