Olympiad math questions, please tell me, can you!

1.Every plum tree is a poem. (Figurative, and metaphorical.) The most important feature of metaphor is the appearance of words such as "is, become".

2.Bright, I look up to you, and I will bow down to you. (This is an extremely bizarre figure of speech called "call.") That is, to call directly to the person or thing that is not in front of you, and to talk to it).

3.It is convinced that dark clouds cannot hide the sun,—— yes, they cannot cover it! (Repeatedly.) There's nothing to say about it)

4.I fell, but the flowers and plants raised their heads, straightened their waists, and smiled. (Anthropomorphism in analogy.) There's not much to say) either

Upstairs, it's really not a philosophical question. Should run to the literature section and ask.

1. Metaphor. 2. Call.

4. Anthropomorphism. These people in front of them all answered, but few people saw the mystery in the third one.

The third is a metaphor, using the sun and clouds as a metaphor for the difficulty of success.

Metaphor. 2.Bright, I look up to you, and I will bow down to you.

Personification. 3.It is convinced that dark clouds cannot hide the sun,—— yes, they cannot cover it!

(Repeatedly.) 4.I fell, but the flowers and plants raised their heads, straightened their waists, and smiled. Personification.

1 Parable. 2 Anthropomorphism.

3 Ask. 4. Anthropomorphism.

I think: 1. Parable.

2. Symbolism. 3 Ask.

4. Anthropomorphism.

1.Exaggeration.

2.Science fiction.

3.Illustrate.

4.Hallucination.

There is a problem with the data in this question, and then remove the highest score and the lowest score, and the average score should be in the middle of the last two values, assuming that the lowest score is.

The highest score is: The difference between the highest score and the lowest score is 4*(

Normal 5 minutes to drive 75 meters, 30 minutes to drive, 5 minutes to repair, the back of the road 15 minutes to complete, the delay of 75 meters of road to 15 minutes.

Within the bell, 75 15 = 5, so it is 5 meters faster than the original.

I won't be able to answer the third question.

Per column: 424 4 = 106 people.

Troop length: (106-1) m.

The queue passes through the rostrum, and the distance is equal to the length of the queue plus the length of the rostrum, which is:

84 + 20 = 104 meters.

It takes to walk through the rostrum: 104 25 = minutes.

A did it for 5 days and B for 9 days.

Solution: Let the total workload be 1, then the efficiency of A is 1 20, and the efficiency of B is 1 12, and if A is done for x days, then B is done for 14-x days.

1 20 * x + 1 12(14-x) = 1 x = 5 then A did 5 days and B did 9 days.

A x day B 14-x days.

x/20 +(14-x)/12=1

3x+70-5x=60

2x=10x=514-5=9

A: 5 days for A and 9 days for B.

Solution: Let each departure, the distance between the two cars is unit 1, the speed of the vehicle is a, the walking speed is b, and the bicycle speed is 3b, then: 1 (a-b)=10......（1）

1/(a-3b)=20……（2）

From (1): a-b=1 10

From (2): a-3b=1 20

1)*3-(2)get:2a=5 20=1 4a=1 8

That is, the interval between departures = the interval distance speed = 1 1 8 = 8 minutes.

10 minutes!

Because the same bus uses 10 points to drive pedestrians first, and then 10 points to drive people, then after he catches 10 minutes, the pedestrian also passes 10 minutes, and the next car comes again, according to this judgment, it should be 10 minutes!

56 days. Bright locust spring crack.

The total number of projects is 1, Team A completes x every day, and Team B completes Y every day. According to the title, there are:

63x+28y=1

48x+48y=1, x and y can be found.

The second team needs to be completed by Z Tian Jing Senyou, then:

42x+zy=1, substituting x,y into it can find z=56 days.

Assuming that the total amount of work in the project is x, then the efficiency of team A is x 10 and the efficiency of team B is x 30

Let's assume that the two teams share Y days. According to the title, during the joint training period of the two teams, team A worked for y-2 days, and team B worked for y-8 days, y>=10

The equation (x 10)*(y-2)+(x 30)*(y-8)=x is divided into x, 3*(y-2)+(y-8)=30, so 4y-14=30, y=11

So it took 11 days to complete.

Set up a day of repair, and B took a break for x days. Limb laughing eggplant.
