眼镜清洁与保养指南

Cleaning your glasses every day is the best way to keep them clear and avoid scratches. However, many people clean them the wrong way. Here’s a simple guide to help you clean your glasses properly.

First, always wash your hands with soap and dry them with a clean towel. Any lotion (洗液) or oil on your fingers may smudge the lenses (镜片). 

Next, wash your glasses under cool running water. This helps remove dust and small particles that could scratch the lenses. Avoid hot water, as it may damage special coatings on the lenses. 

Then, put a small drop of lotion-free dish soap on each lens. Gently rub both sides of the lenses and all parts of the frame, including the nose pads and temples. Be sure to clean where the lenses meet the frame — dirt often builds up there.

After that, rinse the glasses again. Gently shake them to remove extra water. Then, dry the lenses carefully with a clean, lint-free cloth. A microfiber (超细纤维) cloth is perfect for this. Do not use paper towels, tissues, or your shirt — these can scratch or make the lenses dirty.

Finally, check your glasses under light. If there are any marks, wipe them again with a clean microfiber cloth.

Remember:

Never clean glasses with your clothes, sleeve, tissues, or saliva — these scratch lenses or leave lint.

Don’t use household glass cleaners, as their ingredients harm lens coatings.

To store your glasses, always use a clean case.

Never place them lens-down on tables.

If your lenses are badly scratched — or you simply want new glasses — schedule an eye exam with an eye doctor near you.

By following these steps, you can keep your glasses in great condition for longer.

1.1. What does the underlined word “smudge” probably mean in the passage?

A Polish.

B Remove.

C Repair.

D Dirty.

解析：选D。D 词义猜测题。结合前文“清洁眼镜前要洗手”的背景，可知手指上的洗液或油脂会对镜片产生负面作用。并且，下文主要围绕如何“清洁”和避免“划痕”、“灰尘”展开。因此，“smudge”的意思应是让镜片变脏、留下污渍。故选D。

2.2. What can be inferred about the area where the lenses meet the frame?

A It is the most difficult part to dry.

B It requires special attention when cleaning.

C It is usually made of a different material.

D It should only be cleaned by professionals.

解析：选B。B推理判断题。原文第四段提到“Be sure to clean where the lenses meet the frame—dirt often builds up there.”，即镜片和镜框的连接处容易藏污纳垢，因此在清洁时需要给予“特别的关注”。选项B是合理的推断。故选B。

3.3. What is the main purpose of the “Remember” section?

A To list optional suggestions.

B To promote specific brands.

C To emphasize common mistakes.

D To compare different methods.

解析：选C。C推理判断题。原文的“Remember”部分主要连续使用否定结构（Never.../Don’t...）列出了多个清洁和存放眼镜的错误做法，这些做法正是人们在日常生活中容易犯的常见错误。该部分的目的是通过强调这些常见错误来加强读者的印象，避免不当操作。故选C。
