Question 2: I rented a house a few days ago and found clocks hanging on the walls of every room, no matter the living room, dining room or bedroom. What does it mean to look up at the back of the clock? It seems that your landlord is a very picky person. He is probably afraid that renting it to others will bring bad things and that his property will be taken away by you. Therefore, this is just a guess.
Question 3: The idiom "Looking up to see happiness" as opposed to looking up to see happiness is not an idiom. There is only one idiom that contains "looking up":
Meet frequently.
This is a good example.
Explain the metaphor of meeting frequently.
The origin of Zhou Libo's The Storm Part I: "We, a countryman, look up but don't look down. Always your brother's. "
Idioms with complicated structures
Used as predicate, object and attribute; Used in spoken English
Synonym bow your head and see it.
For example, Chapter 5 of Huo Da's * * *: "Look up and see. You are all from the jade shop. How can I sweep you out and kill them all? "
Question 4: Should "looking up at happiness" be placed above or below "happiness"? 50 points is really posted on it, otherwise you can't look up, you can only bow your head. Moreover, custom should be an image. Going out to see happiness originally refers to magpies, which should be in the branches. In this case, the plan is inferior.
Question 5: What does this couplet mean? The exact "height" of Mount Everest will not be announced until August this year.
The so-called height is actually relative. The height of Mount Everest is relative to the sea level. In China, the average sea level of the Yellow Sea measured by Qingdao Tide Station is zero, because the surveyors already know the precise elevation of Lasi County relative to this point, so the height of Mount Everest only needs to be measured from Lasi. In the first half of the survey, the traditional accurate leveling method is still used, that is, a datum point is erected every tens of meters, the height difference is measured with a level, and the height difference is accumulated station by station to calculate the accurate figure, so that it is counted until the foot of Mount Everest.
Since the foot of Mount Everest, the surveyors have changed the measurement method. They chose six relatively flat measuring points between 5200 meters and 6300 meters above sea level, which is convenient for setting up instruments and seeing the summit of Mount Everest.
After the summit team successfully erected the beacon at the summit, the surveyors of these six measuring points used laser rangefinders to send lasers to the summit. After being reflected by the prism on the summit beacon, the straight-line distance and horizontal elevation angle between the measuring points and the summit can be measured, and then the height difference between the summit of Mount Everest and these points can be calculated by using the pythagorean theorem in geometry and other basic principles. This survey method is called "trigonometric leveling", and the height of Mount Everest in China 1975 is 8848. 13m, which is the adopted method. This is the most widely used one in the world at present.
In order to make the height of Mount Everest measured this year more accurate, while using this method, the surveyors also adopted the modern GPS satellite measurement method.
Chen Xianjun, senior engineer of Geodesy Department of National Basic Geographic Information Center, said: "GPS antenna can directly measure the coordinates of the summit by receiving satellite data. At the same time, this coordinate itself contains the amount of elevation. This accuracy is compared with the classical method as a new technical means to ensure the accuracy of our measurement of the altitude of Mount Everest. "
Both of these methods can calculate the distance from the summit of Mount Everest to the zero altitude of China, but the thick snow on the summit of Mount Everest is countless. Accurate measurement of snow depth is an important part to improve the measurement accuracy this time. 1975, the altimeter used a pole inserted in the fragrant snow to measure the depth of ice and snow. This method is prone to errors due to strength, angle, frozen layer and other reasons. This year, China took radar detectors to measure the depth of snow and ice at the peak for the first time, and the obtained data was more accurate.
No matter which measurement method is adopted, there will always be errors in the measured height due to temperature, air pressure, gravity and other reasons, and it is necessary to eliminate the errors through complicated calculations. This calculation process will probably take more than a month, and then the data will be reviewed, so the exact "height" of Mount Everest will not be announced until August this year at the earliest.
Relevant research shows that Mount Qomolangma, the world's highest peak, is still full of vitality, moving tens of millimeters horizontally to the north every year and "growing up" by nearly 10 mm.
1975, the high activity of Mount Everest was measured for the first time in China, and the result was 85438+03m.
Question 6: Lao She looked up at happiness. In the essay "Looking Up at Happiness", she went from a drunken life in the Mid-Autumn Festival to a bleak and desolate youth. There are three times of drunkenness of "non-Yang Guifei" and comedy details like "Wang Xizhi is at my home", but when the dreamland of "looking up at happiness" finally appears, the sad atmosphere reaches * * *. In the layout of the full text, the image of "looking up to see happiness" is also a satire and self-mockery of the actual state of mind of "I", which makes the sadness and banter of this essay muddy. This gentle humor mixed with bitterness and sadness was the main state of Lao She for a long time.
Question 7: What does it mean to look up and see spiders at night? Spiders are generally called K-sons. Looking up to see a spider means looking up to see happiness. There must be something happy.
Question 8: What does it mean to look up to happiness?
