When you do some minor image editing (修正) on your computer screen, you may make some mistakes, so from time to time you’d click undo (撤消).

There are things in life we cannot undo as easily and completely as we would with our computer files. A wrong turn, a hurtful word said to a loved one, a bad move — these we all commit as we walk our life’s journeys, no matter how careful we are in our steps. Once committed, we can no longer undo many of these mistakes, especially because unlike with our computer documents, each thing we do and say has vast impact as they involve not just us — the file that we are working on — but also others, the unopened files and computer programs in our system.

So I guess our life’s mistakes are not like our pencil scrawls (潦草书写) that can be effectively corrected with an eraser, or errors on our computer works that can be undone with an undo button. But there are effective and reliable tools we can use—APOLOGY and FORGIVENESS. Simply click the APOLOGY button when you have committed a mistake that has hurt a loved one and the words “I’m Sorry” will flash on the other person’s screen. But, you have to be truly sorry and you must be prepared not to commit the same mistake again for your APOLOGY to work. Sincerity is definitely a necessary part.

When someone clicks the APOLOGY button and the words “I’m sorry” flash on your screen, all you have to do is click back the FORGIVENESS (原谅) button. It means that you have wholeheartedly accepted the other person’s APOLOGY. But not only that. You also have to click it when someone has sent you back the message “It’s okay. Forget about it.”. It means that you are also forgiving yourself for your mistake; that you won’t keep feeling so bad having committed it.

And lastly, don’t forget to keep clicking the SAVE button. Going through the whole process of editing—of doing and undoing, of apologizing and forgiving — is useless if you fail to save the LESSON for future use. Let the saved file be a reminder of the healing process you once went through to make yourself better; for you not to forget the lesson; and for others to access and learn from.

1.Which of the following is TRUE?

A. However careful we are, we still make mistakes in life.

B. Things we do and say can affect computer programs in our system.

C. We can undo life’s mistakes if we are careful enough.

D. An eraser is an effective tool for our computer works.

2. The APOLOGY button should be clicked when ________.

A. one wants to make the computer work perfectly

B. one’s mistakes won’t influence others any more

C. one is actually saying “I’m sorry”

D. one won’t make the same mistake again

3.What does the underlined word “it” in Paragraph 4 refer to?

A. The UNDO button.                      B. The APOLOGY button.

C. The SAVE button.                          D. The FORGIVENESS button.

4.We need to click the SAVE button in life because ________.

A. we want to go through the whole process of editing

B. we need to learn a lesson from the past mistakes

C. we want to make the healing process faster

D. we need to use the computer properly

高一英语单项填空简单题查看答案及解析

Blue light before bedtime can make it harder to sleep, and the screens on phones, computers, and televisions send out plenty of blue light. This is all true. But if you're focused on blue light as a major problem affecting your sleep or your eye health, it's time to look at it from another aspect.

As Philip Yuhas, a professor of vision, writes at The Conversation, blue light isn’t a uniquely technological evil. It's part of sunlight, and your eyes are exposed to plenty of it all the time. You ' re fine. There are studies in mice that have found blue light can damage their eyes, but mice are nocturnal creatures (夜行动物) whose eyes are different from ours. The pigments (色素) and the lenses (晶状体) of our eyes actually block blue light fairly well--so in a sense, we already have built-in blue blocking protection

Adding more protection isn't likely to help though. You can buy glasses and screen filters (滤光片) that block blue light, but Yuhas points out they are probably a waste of money: these products do not block out much blue light. The leading blue-blocking anti-reflective coating, for example, blocks only about 15% of the blue light that screens send out. You could get the same reduction just by holding your phone another inch from your face.

The American Academy of Ophthalmology doesn't recommend blue-blocking products, either. Instead if you're concerned about your eye health or your ability to get to sleep on time, you already know what to do:

Put the screens away at bedtime. Read a book or find something else to do. While you're using screens take a 20-second break every 20 minutes to look at something 20 feet away ( the "20-20-20 " rule ). If you get dry eyes when you look at screens for a long time, use eyedrops labeled artificial tears.

1.What do people think of blue light generally?

A.It is a necessary part of sunlight. B.It is magical and rare.

C.It is the major factor affecting sleep. D.All electronics send out blue light.

2.What did the studies in mice find?

A.Mice can see clearly in the dark. B.Our eyes actually block blue light well.

C.Eyes can be long exposed to blue light. D.Blue light can damage mice's eyesight.

3.What can we know about blue-blocking products?

A.They block only 15% of the blue light. B.Few have much effect on the blue light.

C.They can prevent much harmful lights. D.They are thought highly of by experts.

4.What could be the best title for the text?

A.How can Blue Light Be Prevented? B.Why does Blue Light Make Sleeping Hard?

C.Are Blue-blocking Products Necessary? D.What will Blue Light Affect Actually?
