As we all know, smoking is harmful to health. When smoking, most of cigarette smoke is inhaled into the lungs, and a small part enters the digestive tract with saliva. Some harmful substances in smoke stay in the lungs, and some enter the blood circulation and flow to the whole body. Under the synergistic effect of carcinogens and cancer promoters, normal cells are destroyed, which can form many diseases such as cancer, hypertension, coronary heart disease, stroke, peptic ulcer, chronic bronchitis and emphysema.

Research shows that if a husband smokes and a wife doesn't smoke and often lives together in a family, the wife's chance of developing lung cancer in the future is higher than that of her husband's wife who doesn't smoke 1 to 3 times. The more the husband smokes, the greater the chance that the wife will get cancer. If someone smokes at home, children at home are prone to bronchitis and pneumonia.

The social harm caused by smoking cannot be underestimated. Cases of fires caused by unlit cigarette butts caused by littering and ignition are frequently reported in newspapers. The most typical case is the forest fire in Daxing 'anling in May of 1987. The fire caused a total loss of 6.910.30 billion yuan. Afterwards, it was found that two of the fires were ignited by three "smokers".

From the above reasons, it tells us that quitting smoking is the only and most effective decision for people all over the country and even the world to improve their health, improve the environment and reduce social harm. The key to quitting smoking is understanding, determination and perseverance. So, dad, for love, for family, for the health of yourself and others, I hope you can put out your cigarette butts and let my mother and I breathe fresh air. I hope you will be firm, overcome all difficulties and take action at once-quit smoking! Okay？

Remember that persistence is victory!

There is no fixed method for writing, but there are rules. We say that "it is better to believe in books than to have no books", and writing a composition in a rigid and dogmatic way will inevitably lead to no real progress. Everything in the world is a process of "easy poverty leads to change, change leads to communication, and general rules last for a long time", and there is no rule out. A lot of practice has proved that excellent compositions always have several things in common, such as unique conception, excellent selection of materials, or brilliant literary talent. Mastering these points will undoubtedly help us get good grades in our composition. No matter how big it is or how detailed it is, it gives some rules and decrees. With these instructions, students will take fewer detours.

Reading is absorption and writing is output. Just as calligraphy needs to be pasted first and painting needs to be sketched, so learning composition should start with imitation. You should be familiar with 300 Tang poems, and you can sing even if you can't write poems. Excellent articles with high quality are always the most critical part of a composition book. Effectively absorb these excellent articles, internalize them into your own things, and produce high-quality compositions. The superiority of composition is no longer a dream!

Without debate and discussion, there will be no progress. Different people will have different ideas after reading the same article. Be generous, actively listen to different opinions, reflect in doubt, grow up in reflection, and don't be narcissistic.

Who doesn't want their composition to be attractive! To tell the truth, if your composition is attractive, then your composition is very successful. In other words, to achieve the effect of "attraction", that is the biggest problem in writing, which needs constant thinking and attention. No matter how well you write, even if you have become a great writer, this problem is still a problem. Here, I want to say that if you want to attract others, you must first attract yourself, touch yourself and make yourself feel particularly interesting. If what you say, the people you write and the things you describe are not new to you, I think your composition is impossible to attract people.

I wish every student can write a good composition!

Tobacco smoke contains at least three dangerous chemicals: tar, nicotine and carbon monoxide. Tar is a mixture of several substances, which will be concentrated into a viscous substance in the lungs. Nicotine is an addictive drug, which is absorbed by the lungs and mainly acts on the nervous system. Carbon monoxide reduce that ability of red blood cells to deliver oxygen to the whole body.

A person who smokes 1.5 to 20 cigarettes a day is more likely to develop lung cancer, oral cancer or laryngeal cancer, which is 1.4 times higher than that of non-smokers.

Smoking is the main cause of chronic bronchitis and emphysema, and chronic lung disease itself will increase the risk of pneumonia and heart disease, and smoking will also increase the risk of hypertension.

Pinyin is as follows:

Chinese pinyin x and y ā n y ǒ u hà i ji à n k ā ng

Ps: When spelling Pinyin, we should always pay attention to the following questions.

1) Don't confuse the front nasal sound with the back nasal sound. Such as in and ing, en and eng.

2) Don't confuse flat tongue sounds with sticky tongue sounds. Such as children and delay, thinking and the world.

4) Words with tone sandhi, such as "178", should be marked according to the original tone, and the tone sandhi should be changed when reading. For example, "one" is originally a sound, but it should be pronounced as a second sound.
