4. 范文背诵
Short-sightedness Among Chinese Students
In recent years, short-sightedness has become a growing concern among Chinese students. According to surveys, a high percentage of senior high students are nearsighted, and the problem is affecting younger age groups increasingly.
There are three main reasons for this trend. First of all, genetic factors contribute to the problem, as children with short-sighted parents are more likely to develop poor eyesight. Second, heavy study pressure means students spend long hours reading and doing close work, which strains their eyes. What's worse, many students spend too much time on electronic devices and lack outdoor activities, which is a key cause of poor eyesight. Bad reading habits, such as reading in bed, also make the problem worse.
To solve this problem, joint efforts are needed. Schools should improve teaching facilities and encourage more outdoor activities. Students themselves should form good eye habits, take regular breaks and do eye exercises properly. It is believed that with proper measures, we can effectively protect our eyesight and enjoy better eye health.

五、阅读理解
A
Short-sightedness, or myopia, has become a major health problem for Chinese teenagers. Studies show that nearly 80 percent of senior high school students in China are nearsighted, and the number is still rising.
There are several causes of this problem. Genetic factors are one reason — if both parents are short-sighted, their children have a higher risk of poor eyesight. However, lifestyle plays a bigger role. Today's students spend most of their time studying indoors and looking at screens. They have less time for outdoor activities, which is proven to help protect eyesight. Bad reading habits, such as reading in bed or in poor light, also damage eyes.
To solve this problem, schools and families should work together. Schools can arrange more outdoor classes and improve classroom lighting. Students should form good eye habits: take a break every 40 minutes, look at distant objects, and do eye exercises regularly. Most importantly, they should spend more time outdoors in natural light. Protecting eyesight is important for everyone's long-term health.
1. What is the main idea of the second paragraph?
A. Genetic factors cause short-sightedness.
B. Bad habits are the main cause of poor eyesight.
C. There are multiple causes of short-sightedness.
D. Outdoor activities can protect eyesight.
2. Which of the following is NOT mentioned as a cause of short-sightedness?
A. Genetic influence. B. Lack of outdoor activities.
C. Poor eating habits. D. Bad reading habits.
3. What can we learn from the passage?
A. Short-sightedness is only a problem for senior high students.
B. Lifestyle has a greater influence on eyesight than genes.
C. Doing eye exercises is the best way to improve eyesight.
D. The number of nearsighted students is dropping in China.
【答案】1. C 2. C 3. B
【解析】本文介绍了中国学生近视的现状、成因及解决办法。
1. 第二段从遗传、生活方式、用眼习惯三个方面分析近视成因,C 项最能概括主旨。
2. 文中提到遗传、缺乏户外活动、不良阅读习惯,未提及饮食习惯,故选 C。
3. 根据第二段 “lifestyle plays a bigger role” 可知生活方式比基因对视力影响更大,故选 B。
B
Genome editing is a new technology that changes the DNA of living things. It allows scientists to correct, add or delete parts of the genetic material. Many people believe it will bring great advances in medicine.
With genome editing, doctors could treat genetic diseases by changing the faulty genes. It could also help prevent diseases before they develop. For example, scientists could edit genes that make people more likely to get cancer. In the future, this technology might even help solve the problem of antibiotic resistance.
However, genome editing also raises many questions. One big concern is "designer babies" — babies whose genes are edited to have certain advantages. This could lead to unfairness in society. There are also safety risks: wrong changes to genes might cause unexpected problems.
Scientists say that proper controls are needed. Genome editing should be used for medical treatment, not for making "perfect" babies. With careful management, this technology can bring huge benefits to human health.
4. What is the main advantage of genome editing in medicine?
A. It can create designer babies.
B. It can treat and prevent genetic diseases.
C. It can change all human genes.
D. It can solve all health problems.
5. What is the problem with "designer babies"?
A. They may have more diseases.
B. They are not as smart as normal babies.
C. It may cause social unfairness.
D. It is against the law everywhere.
6. What is the author's attitude towards genome editing?
A. It is completely safe and should be widely used.
B. It is too dangerous and should be stopped.
C. It has benefits but needs proper controls.
D. It has more disadvantages than advantages.
7. What is the best title for the text?
A. The History of Genetic Research
B. Genome Editing: Possibilities and Concerns
C. How to Prevent Genetic Diseases
D. Designer Babies: Our Future?
【答案】4. B 5. C 6. C 7. B
【解析】本文介绍了基因组编辑技术的医疗价值、潜在风险及争议。
4. 根据第二段可知基因组编辑可治疗和预防遗传病,故选 B。
5. 根据第三段 “This could lead to unfairness in society” 可知设计婴儿可能引发社会不公,故选 C。
6. 文章既讲了技术的益处,也提到风险,最后提出需要合理管控,故选 C。

Short-sightedness Among Chinese Students
In recent years, short-sightedness has become a growing concern among Chinese students. According to surveys, a high percentage of senior high students are nearsighted, and the problem is affecting younger age groups increasingly.
There are three main reasons for this trend. First of all, genetic factors contribute to the problem, as children with short-sighted parents are more likely to develop poor eyesight. Second, heavy study pressure means students spend long hours reading and doing close work, which strains their eyes. What's worse, many students spend too much time on electronic devices and lack outdoor activities, which is a key cause of poor eyesight. Bad reading habits, such as reading in bed, also make the problem worse.
To solve this problem, joint efforts are needed. Schools should improve teaching facilities and encourage more outdoor activities. Students themselves should form good eye habits, take regular breaks and do eye exercises properly. It is believed that with proper measures, we can effectively protect our eyesight and enjoy better eye health.

五、阅读理解
A
Short-sightedness, or myopia, has become a major health problem for Chinese teenagers. Studies show that nearly 80 percent of senior high school students in China are nearsighted, and the number is still rising.
There are several causes of this problem. Genetic factors are one reason — if both parents are short-sighted, their children have a higher risk of poor eyesight. However, lifestyle plays a bigger role. Today's students spend most of their time studying indoors and looking at screens. They have less time for outdoor activities, which is proven to help protect eyesight. Bad reading habits, such as reading in bed or in poor light, also damage eyes.
To solve this problem, schools and families should work together. Schools can arrange more outdoor classes and improve classroom lighting. Students should form good eye habits: take a break every 40 minutes, look at distant objects, and do eye exercises regularly. Most importantly, they should spend more time outdoors in natural light. Protecting eyesight is important for everyone's long-term health.
1. What is the main idea of the second paragraph?
A. Genetic factors cause short-sightedness.
B. Bad habits are the main cause of poor eyesight.
C. There are multiple causes of short-sightedness.
D. Outdoor activities can protect eyesight.
2. Which of the following is NOT mentioned as a cause of short-sightedness?
A. Genetic influence. B. Lack of outdoor activities.
C. Poor eating habits. D. Bad reading habits.
3. What can we learn from the passage?
A. Short-sightedness is only a problem for senior high students.
B. Lifestyle has a greater influence on eyesight than genes.
C. Doing eye exercises is the best way to improve eyesight.
D. The number of nearsighted students is dropping in China.
B
Genome editing is a new technology that changes the DNA of living things. It allows scientists to correct, add or delete parts of the genetic material. Many people believe it will bring great advances in medicine.
With genome editing, doctors could treat genetic diseases by changing the faulty genes. It could also help prevent diseases before they develop. For example, scientists could edit genes that make people more likely to get cancer. In the future, this technology might even help solve the problem of antibiotic resistance.
However, genome editing also raises many questions. One big concern is "designer babies" — babies whose genes are edited to have certain advantages. This could lead to unfairness in society. There are also safety risks: wrong changes to genes might cause unexpected problems.
Scientists say that proper controls are needed. Genome editing should be used for medical treatment, not for making "perfect" babies. With careful management, this technology can bring huge benefits to human health.
4. What is the main advantage of genome editing in medicine?
A. It can create designer babies.
B. It can treat and prevent genetic diseases.
C. It can change all human genes.
D. It can solve all health problems.
5. What is the problem with "designer babies"?
A. They may have more diseases.
B. They are not as smart as normal babies.
C. It may cause social unfairness.
D. It is against the law everywhere.
6. What is the author's attitude towards genome editing?
A. It is completely safe and should be widely used.
B. It is too dangerous and should be stopped.
C. It has benefits but needs proper controls.
D. It has more disadvantages than advantages.
7. What is the best title for the text?
A. The History of Genetic Research
B. Genome Editing: Possibilities and Concerns
C. How to Prevent Genetic Diseases
D. Designer Babies: Our Future?
