At some point in elementary school, your science teacher may explained to you that there are 365 days in a year because that's how long it takes for Earth to complete one full journey around the sun. What they might not have explained, however, is that it's not exactly 365 days—it’s actually closer to 365. 2421 days.
So, if we want our calendar year to begin right when Earth begins a new turn around the sun, we have to account for roughly an extra quarter of a day each year, or one day every four years. History.com reports that the Egyptians had already been doing this for a while before Europe finally caught on in 46 BC, when Roman Emperor Julius Caesar and astronomer Sosigenes put their heads together to come up with what we now call the Julian calendar, which includes 12 months, 365 days, and an additional ''leap day'' every four years on February 29.
But rounding 0.2421 up to 0.25 each year created an issue, because it didn't quite add up to a full day every four years—and that tiny difference meant that after 128 years, the calendar year ended up starting a day before Earth had completed its journey around the sun. By the 14th century, the calendar year was starting 10 days before Earth finished its orbit.
In 1582, Pope Gregory XIII sought to correct the error by suggesting that we simply skip a leap day every so often. His Gregorian calendar, which we still use today, rules that we skip the leap day during years which can be evenly divided (被整除) by 100 but not by 400. For instance, the year 2000 included a leap day because it can be divided by 100 and 400; the year 2100, on the other hand, will not include a leap day, since it's evenly divided by 100, but not by 400.
Gregory XIII’s correction to Caesar's overcorrection is itself a bit of an under-correction, so we'll probably need to reevaluate our leap day design again in about 10,000 years.
1.What do the underlined words ''put their heads together'' in paragraph 2 mean?
A.Come across each other. B.Bump their heads together.
C.Compete against each other. D.Combine their efforts.
2.According to Gregorian calendar, which year may include a leap day?
A.2100. B.1600.
C.1800. D.2020.
3.What can we learn from the passage?
A.Emperor Julius Caesar was also an astronomer.
B.Today's calendar exactly agrees with the sun's turning.
C.The 10-day early start in calendar will always exist.
D.The Gregorian calendar is not yet the most accurate.
4.What's the purpose of this passage?
A.To point out a mistake made by your science teacher.
B.To explain how long Earth makes a trip around the sun.
C.To explain in detail why the leap day is needed.
D.To explain the reason why we need a calendar.

It may help you to know that there is no such thing as a perfect speech. At some point in every speech, every speaker says something that is not understood exactly as he has planned. Fortunately, such moments are usually not obvious to the listeners, why? Because the listeners do not know what the speaker plans to say, they hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser. When such moments occur, don’t worry about them. Just continue as if nothing happened.
Even if you do make an obvious mistake during a speech, that doesn’t really matter. If you have ever listened to Martin Luther King’s famous speech—“I have a dream”, you may notice that he stumbles over his words twice during the speech. Most likely, however, you don’t remember. Why? Because you were fixing your attention on his message rather than on his way of speech-making. People care a lot about making mistakes in a speech because they regard speech-making as a kind of performance rather than as an act of communication. They feel the listeners are like judges in an ice-skating competition. But, in fact, the listeners are not looking for a perfect performance. They are looking for a well-thought-out speech that expresses the speaker’s ideas clearly and directly. Sometimes a mistake or two can actually increase a speaker’s attractiveness by making him more human.
As you work on your speech, don’t worry about being perfect. Once you free your mind of this, you will find it much easier to give your speech freely.
1. The underlined part in the first paragraph means that no one will _________.
A. be smarter than you
B. do better than you
C. notice your mistakes
D. know what you are talking about
2.You don’t remember obvious mistakes in a speech because _________.
A. you find the way of speech-making more important
B. you don’t fully understand the speech
C. you don’t know what the speaker plans to say
D. you attention is on the content
3.It can be inferred from the passage that _________.
A. one or two mistakes in a speech may not be bad
B. giving a speech is like giving a performance
C. the listeners should pay more attention to how a speech is made
D. the more mistake a speaker makes, the more attractive he will be
4. What would be the best title for the passage?
A. How to Be a Perfect Speaker
B. How to Make a Perfect Speech
C. Don’t Expect Mistakes in a Speech
D. Don’t Expect a Perfect Speech
