Are you a shy person? Does the thought of having a conversation make your stomach turn? That’s OK. Everyone is a little shy. This article may help you overcome (克服) your shyness.
1. This seems clear – the best way to meet people is to actively look for places out where you can meet people! Go to the dance party at your school or the Christmas get-together. Try to meet at least one person by the end of the night.
2. Even though this may sound strange – stand in front of a mirror or close your eyes, and then imagine yourself talking to someone – it is very helpful.
3. Making new friends is a great way to overcome shyness. Although that may sound useless, it really isn’t.
4. For example, if you like art, you can consider painting something for a party. It will be easier to make you feel comfortable. On the other hand, don’t be afraid to discover some new interests.
5. Take a moment to look at yourself. Are you the kind of person who wears dark clothes? This makes you very unapproachable (不可亲近的). Wear brighter clothes. Go from wearing black, brown, and blue to wearing green, yellow and oranges. Remember, you don’t always have to change your look. You can just simply make your expression more friendly. Let people know that it’s OK to talk with you.
Harmful microbes (微生物) like bacteria (细菌), viruses (病毒) and other germs (病菌) are pathogens (病原体). They may enter your bodies and make you ill. The immune system (免疫系统) is the body’s defence (防卫) system that protects you from illness and disease caused by the pathogens.
The immune system is made up of non-specialized defences such as skin, tears and the acidic juice produced by the stomach, keeping you from the pathogens. It also has some highly specialized defences, which are different kinds of immune cells (细胞), grouped into phagocytes (噬菌细胞) and lymphocytes (淋巴细胞). Phagocytes are a type of white blood cell. They are swimming around in your blood stream, always on the lookout for antigens (抗原) —the pathogens that have entered your bodies. Whenever they see one, they will eat it. However, some antigens are hard to find and kill. Then lymphocytes, which are also white blood cells and the main types are B cells, T helper cells and T killer cells, will be the killers of the sneaky antigens. B cells, T helper and T killer cells work together to find and kill these antigens. B cells produce substances, called antibodies, which stick to the antigen. When that happens, it will tell the T helper cells to come over and either: 1. help the B cells kill the antigen, or 2. call the phagocytes or T killer cells to move in for the kill. Once a B cell or a T cell attacks an antigen, they create cells to “remember” it. Those “memory cells” hang out in your blood and if they see the same antigen again, they quickly recognize (识别) it so your immune system can act faster at killing it.
The immune system is more powerful than you probably imagine. Scientists from the University of Pennsylvania recently took immune cells from three patients with leukemia (白血病), then genetically changed them into “serial killer” cells to attack cancer cells. The study was small but the results were ground-breaking. The modified immune cells increased at least 1,000 times in the body and killed all the cancer cells. Therefore, more “memory cells” were created.
The immune system can be developed. Eating lean protein food (beef, beans) and food rich in vitamins A, C and E (sweet potatoes, carrots)，taking a 30-minute walk every day and reducing your stress levels, will help you achieve it.
1.The immune system can _________.
A. keep you from antibodies. B. protect you against antigens.

D. Phagocytes, B cells, T helper and T killer cells work together.
3.After a B cell or a T cell attacks an antigen, they create _________.
A. phagocytes B. lymphocytes C. memory cells D. serial killer

A. Less antigens can be killed by the immune system
B. The immune system can be changed into the “serial killer”
C. White blood cells act less quickly in the immune system
D. The immune system can be made more powerful
