第五部分：阅读理解 (20分)

Directions: 阅读下列两篇短文，并根据文章内容回答后续问题。

Passage A (跨学科：生物科技 + 伦理)

In the realm of genetic engineering, the development of CRISPR-Cas9 has been heralded as a breakthrough akin to the discovery of the microscope. This gene-editing tool allows scientists to make precise, targeted changes to the DNA of living organisms with relative ease and low cost. The potential applications are staggering: from curing hereditary diseases like cystic fibrosis and Huntington‘s disease to engineering crops that can withstand drought and pests.

However, this powerful technology also opens a Pandora’s box of ethical dilemmas. The concept of “germline editing”—making changes to the DNA of embryos that will be passed down to future generations—has sparked intense global debate. Proponents argue that it could eradicate devastating genetic disorders from a family line forever. They envision a future where parents can spare their children and grandchildren from inheriting fatal diseases.

Questions:

1. What is the primary purpose of the first paragraph?
   A. To argue against the use of CRISPR.
   B. To introduce CRISPR and its positive potential.
   C. To compare CRISPR to the microscope.
   D. To explain the technical process of gene editing.
2. The phrase “Pandora‘s box” in paragraph 2 is used to illustrate that CRISPR ______.
   A. is a mysterious and ancient discovery
   B. brings with it many unforeseen problems
   C. contains only negative outcomes
   D. is the ultimate solution to genetic diseases
3. According to the passage, what is the main ethical concern associated with “germline editing”?
   A. The high cost makes it unavailable to the poor.
   B. It could be used for non-therapeutic enhancements, leading to social issues.
   C. It is not effective in treating single-gene disorders.
   D. Scientists are moving too slowly in their research.
4. What can be inferred about the author‘s view on the future of CRISPR?
   A. It should be banned immediately to prevent disaster.
   B. Its development should be guided by careful ethical consideration and regulation.
   C. The benefits far outweigh any potential risks.
   D. Only therapeutic uses in adults should be allowed.

Passage B

Memory is not a single entity but a complex collection of systems. Broadly, we can distinguish between short-term memory (STM) and long-term memory (LTM). STM acts as the brain‘s “scratch pad,” holding a limited amount of information for a short period—like a phone number you just looked up. Classic research by George Miller suggested that the capacity of STM is about seven items, plus or minus two, a phenomenon often referred to as “The Magical Number Seven.”

However, this concept was later refined by psychologists Alan Baddeley and Graham Hitch, who proposed a more nuanced model they called “working memory.” Unlike the passive, temporary storage implied by STM, working memory is an active system. It not only stores information temporarily but also manipulates and processes it to perform complex cognitive tasks such as learning, reasoning, and comprehension. For instance, when you mentally calculate the total cost of items in your shopping cart while comparing prices, you are using your working memory.

Questions:

1. 5. What is the main difference between “short-term memory” and “working memory” as described in the passage?
   A. Working memory has a larger capacity than short-term memory.
   B. Short-term memory is active, while working memory is passive.
   C. Working memory involves both storage and manipulation of information.
   D. Short-term memory is only for numbers, while working memory is for language.
2. The example of calculating the total cost of items in a shopping cart is used to illustrate ______.
   A. the limited capacity of short-term memory
   B. the function of working memory in complex tasks
   C. the difference between the phonological loop and the visuospatial sketchpad
   D. George Miller‘s “Magical Number Seven” theory
3. According to the passage, why might a student struggle with a math word problem?
   A. They lack the mathematical knowledge stored in long-term memory.
   B. The task demands exceed their working memory capacity.
   C. They are not using the central executive part of their brain.
   D. The “Magical Number Seven” prevents them from holding all the words.
4. What is the author’s purpose in writing this passage?
   A. To criticize old models of memory.
   B. To explain a model of memory and its practical implications.
   C. To provide tips on how to improve one‘s memory.
   D. To argue that memory is too complex to study.

第六部分：写作 (30分)

Directions: 请从以下两个题目中任选其一进行写作，字数要求不少于250词。

Option 1: 议论文
In the age of social media, some people argue that online connectivity has weakened genuine human relationships, leading to increased feelings of loneliness and isolation. Others believe that it has strengthened bonds by allowing people to maintain contact across distances and find communities of like-minded individuals.

Discuss both these views and give your own opinion.
