Rubella: The disease is usually fever, and the body temperature is not too high. 1-2 days later, a reddish rash appeared on the face and neck skin, which quickly spread to the whole body within 24 hours, but most of the palms and soles had no rash. Confirmed patients should receive isolation treatment. Spring is the season of high incidence of respiratory infectious diseases.

Etiology includes cricopharyngeal muscle movement disorder, neuromuscular disease and local injury, and the pathogenesis is probably related to the dysfunction of pharyngeal muscle or upper esophageal sphincter, such as abnormal hypertension, hypotension or relaxation of cricopharyngeal muscle. The results show that the scores of somatization, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, terror, paranoia, psychosis and additional symptoms in the experimental group are higher than those in the domestic norm, and there are significant differences, indicating that hysterical hysteria patients do have serious emotional disorders, which are related to more psychosocial stress. At the same time, due to the lack of correct understanding of the disease, patients often regard the symptoms of throat discomfort caused by bad mood, nervousness, fatigue or physical weakness as organic lesions, and repeatedly seek medical treatment for various examinations. This kind of medical treatment behavior itself strengthens the role of patients in & rdquo, and on the basis of the original symptoms, it increases psychological or iatrogenic bad hints, causing tension, fear and pessimism. , further aggravate the symptoms and form a vicious circle.
4. Basketball rules and basic knowledge
If you want to play basketball well, you can't just practice it by yourself. If you are a novice, you must always practice in actual combat. The more you play in actual combat, the faster your basketball skills will improve, especially playing 3-on-3 at half-time. In addition, field experience is also an important part of playing basketball well, and it should also be honed in actual combat.

Don't be afraid of hardship. Because basketball relies on real skills, no pains, no gains. Don't be afraid to play badly. If you don't cooperate well, you won't dare to throw it. What basketball fears most is timidity. Throw it when you have the chance. If there is a gap, you will suddenly. I believe that no one who claims to be a master is a master since playing basketball. When you are a rookie, you should play with confidence. You should have your own style. The most important thing is to dare to fight. It doesn't matter how many times you shoot it. It doesn't matter if you can't participate. The key is to fight hard on the court and be passionate about basketball.

Hehe, play with your own characteristics. When practicing, don't be too fancy. Should be practical and beautiful. Speed is a very important link. I'm not asking you to practice 100 meters. As long as you start fast enough, you need good lower limb strength and ball control skills. It doesn't need much. You just need to practice. If you are already an expert, you just want to improve your skills and tactics. You don't need to look at the heels on it. According to your own position, your body will establish a fixed system for effective training. As long as you persist every day, you can improve. It is difficult to make progress at this stage. Besides, you need some fierce confrontation. I won't say it's useless. This is my own experience. I hope it helps you. Today's basketball is tense, and * * * is full of charming charm.
It should not only have speed, but also have height; Not only should the attack be sharp, but also the defense should be solid; Not only must there be tacit collective cooperation, but also superb personal skills. Therefore, only a team with all-round and balanced development can cope with the increasingly fierce competition and defeat its opponents. In the unpredictable basketball kingdom, basic skills are still crucial.
A solid basic skill is an indispensable condition for becoming a basketball star. Skilled personal skills are the basis of all tactical cooperation.
"Flying man" Jordan said: "Basic skills are the most important part of my nba game, and any achievements I have made can be attributed to my basic skills. No matter what you want to do or how you want to do it, if you want to do your best, you can't ignore basic training. "
Anyone who wants to learn basketball and show his talents on the court can only achieve his goal by starting from the most basic dribbling, shooting, breakthrough and defense, working hard step by step and paying hard sweat.

Pay attention to the offensive cooperation of the whole team, and expect possible offensive cooperation and opportunities in their own position.
2. Try to observe the situation of each potential receiver and defender in advance. 3. Pass the ball in place, pass the ball over, and try to pass the ball to others. Generally pass the ball to the position where the partner is far away from the defender.
4. Learn to pass the ball with both hands. Often when defenders pay attention to defending strong players, it is more effective to pass the ball with weak hands. 5. Pass the ball in time.
Problems that should be paid attention to when catching the ball. : 0 1 1: 1. Within the range of our team's tactical requirements, actively seek for the ideal angle of catching the ball forward or with the ball.
2, should be combined with the signal required by the passer and clear passing position, to be able to control a wider range of catching (especially inside players) to give the passer a sense of security. 3. Cooperate with the next attack as soon as possible while catching the ball.
At the moment of catching the ball, we should use the inertia of the ball to make it "stick" in our hands. Problems that should be paid attention to in shooting.
: 0 14: 1, you must first know your distance and angle from the shooting. 2. Judge the situation of the defender.
3. Be sudden and grasp the shooting opportunity. 4. Try to follow the rhythm you are used to.
5. It's better to rebound and shoot. 6. Focus on shooting actions and shooting targets.
7. I firmly believe that I can hit the basket. Problems that should be paid attention to when dribbling: 0 12: 1. Always keep the ball within your control. 2. Hold your head high, observe the situation on the court at any time, and pass the ball purposefully. 3. Keep away from the defenders' dribbling.
You should learn to dribble with both hands. 5. Try not to dribble when you can pass the ball.
6. Don't dribble to the area where players gather and stay away from the sideline and corner area. 7. To master the rhythm in dribbling, there should be not only changes in direction, but also changes in speed.
8. Don't stop dribbling when there is no good chance to pass the ball, so as not to be caught by the other side or cause a 5-second violation, especially when pressing. Problems that should be paid attention to when holding the ball to break through.
: 0 18: 1. When you break through with the ball, you should combine it with shooting and passing. 2. Defenders with quick response and flexible movement can use fake actions more, while defenders with slow response and poor mobility can use breakthrough start to break through defenders.
3. The center of gravity before the breakthrough should be low and stable. 4. Dare to cling to the defender and make reasonable physical contact when breaking through.
Precautions for defense: 005: Under normal circumstances, the defender should stand on the side with the ball between the opponent and the basket, and the position and distance of the defender must be adjusted in time according to the transfer of the ball. For opponents who are close to the ball, they should take oblique defense when facing the opponent's side ball.
For opponents who are far away from the ball, they often take a flat defense facing the ball. The defender must walk in front of the attacker to make the defense destructive and aggressive.
The main principle of defending the center is to minimize the center's catching the ball in the lower part of the restricted area and destroy its contact with the peripheral players. For the center in the lower part of the penalty area, forward defense should be adopted if necessary (the body is close to the center's front, his legs are crouched, and he is ready to jump up and interrupt the opponent's lob at any time). It is very difficult for a center who is a big threat to rely on individual defense, so we must pay attention to cooperating with defense.
