Tolstoy's reading comprehension of Shark is urgent. Explanation 1. Swim fast, skilled and sensitive.

The children are smart and the old gunner is decisive.

When encountering setbacks and difficulties, we should think calmly.

A simple function problem! Urgent ... thank you for your help! The abscissa of b is x= 1 and the ordinate y=2x=2, that is, B( 1, 2).

One coordinate is (0,3)

Let the analytical formula be y = kx+b.

3=0+b

2=k+b

Get b = 3, k =- 1.

That is, y=-x+3.

Be anxious, ask the computer expert. Error 65 1: Error 65 1 is a prompt code under WIN7 system, which is equivalent to error code 678 1 under XP system. Error 65 1: The remote computer is not responding. Generally, there may be a broadband cat or a problem with the line, which causes the broadband cat to be out of sync, or the equipment in the operator's computer room or the computer system. 2. Check the status of broadband cat. Whether there is a DSL or LINK light on all the time (different brands of cats have different English signs), the DSL or LINK light on the broadband cat indicates the communication status between your broadband cat and the equipment in the operator's computer room, and it should be on normally. If it doesn't light up, there is probably something wrong with your telephone line. It is recommended that you call the operator's customer service phone directly for repair. Usually it will be processed in one or two working days.

It's urgent. it's urgent Girlfriend's birthday I folded 999 paper cranes! What should I write in my greeting? Gifts also depend on the needs of both parties. When a friend gives a birthday present, he should give the other person what he wants. If it is just a gesture, it is not worth paying too much. Sometimes elders give us gifts on holidays, which actually meet their psychological needs, but what they give is not what we really need.

Personally, I think that your sending 1000 paper cranes is purely your own idea, which is inconvenient for the other party to accept. What you sent is totally rubbish. In this case, I think you can only think for yourself and try to meet your psychological needs like gifts from your elders. If possible, try it and see if you can impress each other.

I hope you can seriously consider it. If the other party doesn't need these paper cranes, I suggest you don't make garbage for the other party. After folding for so long, you have finished this production, and you are addicted to it. Let yourself handle it. The Spring Festival is coming soon. You might as well have a try and see if these paper cranes you folded can sell some money.

If these paper cranes are from the other party, I think you should do more processing and string them with beautiful ropes, so that the other party can hang them in the room, so that birthday parties can also play a practical role and can also be used to decorate the room during the Chinese New Year.

Speaking of which, my method has also come out. String paper cranes one by one, so that you can carry a string of paper cranes on your shoulders, give them to each other, or sell them. This is a good method.

Only 200 words is enough for the beautiful scenery of the countryside ~ ~ When you visit the green mountains and green waters, when you bathe in the sun and rain, when you walk under the stars, when you have a rest in the grass and wild flowers ... I think no one will be surprised by the masterpieces created by nature.

I also visited many places in my memory, including the steep Huangshan Mountain, the beautiful Guilin, and ... But that trip to Jiuzhaigou completely surprised me.

Jiuzhaigou can be described by more than one word "beauty"-there are quaint plank roads, colorful forests, green lakes, misty clouds, majestic snow-capped mountains, unique or peculiar waterfalls ... Oh, yes, there are Tibetan stockyards full of ethnic customs ... Perhaps, having any of them is a beautiful scenery.

Before, we heard that Tibetans called the lake here Haizi-the son of the sea, which is true. When I first saw the lake in Jiuzhaigou, I really took it as blue lagoon, the son of the sea, which was worse than the blue ocean. However, after all, it is a lake, which is much smaller than the boundless sea. No wonder Tibetans call the lake here Haizi! Walking on the plank road near the water's edge, when you look around, the blue lake water and the color of the colorful forests on the surrounding mountains form a strong sense of layering. The color of the tree is green, dazzling red, simple dark green and elegant yellow ... Seeing the wonderful combination of the color of the lake and the colorful forest, I can't help but be grateful to nature, the grace of nature, and the wonderful visual enjoyment that nature has brought us!

In addition to the blue water color, Haizi has another feature-clarity. The lake is deep, even as deep as 103 meters, but it feels only one meter deep-because you can easily see the bottom of the lake, and the fish at the bottom of the lake are either "motionless" or "dead". Some people even muttered: "It is said that there is no fish when the water is clear, but why are all the fish here so happy?" What's more, he recited Chairman Mao's poem: "There are countless beautiful people in the mountains and rivers, and heroes are bent over." Yes, in Jiuzhaigou, who will not be impressed by the creation of nature? Who wouldn't be grateful to nature?

After reading all kinds of Haizi, I still feel something is missing. After thinking about it, I suddenly found that there seems to be some lack of vitality here. All the scenery and colors here are beautiful, gorgeous and dazzling, but after all, they are still life, lying quietly, making people unaware of the slightest vitality. With such a desire to find some vitality, I kept looking around, but I didn't find the vitality in my heart. So, I took a few steps forward, hoping to make new discoveries. For an instant-when my eyes crossed a mountain, I saw a reed in front of me. I blinked-I didn't read it wrong, but generally speaking, reeds grow below 800 meters above sea level, but Jiuzhaigou's altitude reaches 3000 meters. Why do reeds grow on such a plateau? Besides, why do the reeds grow taller and taller here?

Yes, the plateau is undoubtedly a harsh environment for reeds, but these reeds did not shrink back and gave up this place-they chose to adapt to the environment, chose to bravely challenge their living environment, chose to face the reality, and chose to rely on their own efforts to prove that reeds can also grow at an altitude of 3000 meters or even higher! As a result, they succeeded, successfully growing on this plateau, even higher and bigger than those reeds settled on the flat land.

Walking on the plank road, I can't help but be impressed by this group of tenacious reeds. In my eyes, they are not just a group of reeds-in my eyes, they symbolize the indispensable spirit and tenacious will of today's people. Perhaps, if a person can be like this reed, not succumb to the harsh living environment, face the reality and have a tenacious will, then he will be as successful as this reed on the plateau!

With this understanding, I can't help but feel more grateful to nature, not only because it brings us visual enjoyment, but also because nature gives me inspiration in life.
