Water skiing
Water skiing is an exciting water sport that can be a ton of fun. You will get to have a happy and joyful adventure every time you go out on the water. 1. However, once you start, water skiing is a sport you can enjoy whenever you have a boat and enough flat water.
2. Every water skier needs water skis—these are different from snow skis and they also differ depending on the size of the skier and the experience level of the skier. 3. You will need to find at least two people to go with you on your water skiing adventure. You and everyone you go with will have more fun if the friends you go with also want to water ski. You need a boat, naturally. 4.
For your first time water skiing, you may want to either take a lesson from an expert or find a friend that has experience and is willing to teach you. 5. The observer rides in the boat, but watches the water skier for any signals and helps the driver know when to start and stop.
A.It’s no hard task to learn.
B.It takes a little patience to learn.
C.Of course, no one can water ski alone.
D.Once prepared, a skier can start the game on his own.
E.You will also need a water skiing cable and a life jacket.
F.Before you start water skiing, there are a few supplies you’ll need.
G.Of your two helpers, you need one to drive the boat and one to observe.
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.
Unconfident children can improve their performance in math tests simply by saying nice things to themselves, a study suggests.
A total of 212 fourth to sixth graders, aged between 9 to 13 years old, took part in the research. The children completed a math test in two parts. At the end of the first half, researchers asked the first group of kids to talk to themselves about the amount of effort they would put into the second half of the test before carrying on. The children quietly told themselves: ''I will do my very best. '' Another group was told to consider their ability, by repeating the phrase: ''I am very good at this. '' The children were instructed to write down their given phrase, and repeat it to themselves while working on the problems, particularly when they found the work challenging. The rest of the children acted as the control group, and weren't required to say anything. A few days before completing the test, all the kids completed a survey on how they viewed their own and others' abilities.
Compared with kids who didn't do what is known as self-talking, those with low self-confidence who spoke about the effort they'd make did better in the second half of the test. The data led the researchers to conclude children who struggle with negative thoughts about their competence could improve their achievements in school by telling themselves they will put effort into a task.
However, the team said they did not find the same result among children with low self-confidence who spoke to themselves about ability, for self-talk about effort is the key. Meanwhile, they pointed out the findings may not relate to children of other ages, and more research is needed to explore this.
1.How was the research conducted?
A.By telling students to talk about their effort. B.By comparing three groups of students.
C.By instructing students to repeat phrases. D.By telling students not to say anything.
2.What conclusion did the researchers draw?
A.Students may benefit from talking about effort.
B.Students should talk about effort in the tests.
C.Students can benefit from talking about ability.
D.Self-talking helps all students do better in tests.
3.We can infer from the last paragraph that the research team is _________.
A.careless B.cautious
C.stubborn D.competitive
4.In which section of a newspaper may this text appear?
A.Entertainment. B.Health.
C.Education. D.Sports.
