【题目】At the beginning of every year we promise ourselves we will live a healthier life, and exercise more. The year tarts with the best of intentions, but many times we are unable to keep up with very high goals. Good news is that a healthy lifestyle is achievable and it's all about making small changes that make a difference.

News on healthy lifestyles says that the key is moderation and consistency. There are so many health and well-being products out there in the market promising many things. And although many may be true, select carefully.

The basics of a healthy lifestyle is maintaining a balanced diet and doing regular exercise. By eating well, it means really to make sure you include plenty of vegetables and fruit preferably in season in your diet, avoid fried and junk foods and foods high in sugar as well as processed foods. Eating fresh homemade meals rather than ready-made meals which are high in salt and sugar is always the better option. Reducing alcohol intake, drinking plenty of water and supplementing your diet with healthy snacks like nuts and seeds.

For external care choose natural skin care products and hair care oil. Natural beauty care involves using natural moisturizers like Argan oil, Coconut oil and Sweet Almond oil. These nourish the skin far more than counter creams full of chemicals. Skin reflects what we put inside of us, so a healthy diet with plenty of greens and healthy protein will make your skin brighter.

Of course exercise is essential but the key is regular and consistent exercise. So walking three times a week for 45 minutes is much more beneficial than a binge workout once a week.

【题目】A

Amyotrophic lateral sclerosis(ALS) (肌萎缩性侧索硬化症) is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary(随意的) muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.

A-myo-trophic comes from the Greek language. "A" means no or negative. "Myo" refers to muscle, and "Trophic" means nourishment--"No muscle nourishment." When a muscle has no nourishment, it "atrophies" or wastes away. "Lateral" identifies the areas in a person's spinal cord where portions of the nerve cells that signal and control the muscles are located. As this area degenerates it leads to scarring or hardening ("sclerosis") in the region.

As motor neurons degenerate, they can no longer send impulses to the muscle fibers that normally result in muscle movement. Early symptoms of ALS often include increasing muscle weakness, especially involving the arms and legs, speech, swallowing or breathing. When muscles no longer receive the messages from the motor neurons that they require to function, the muscles begin to atrophy (become smaller). Limbs begin to look "thinner" as muscle tissue atrophies.

What Types of Nerves Make Your Body Work Properly?

The body has many kinds of nerves. There are those involved in the process of thinking, memory, and of detecting sensations (such as hot/cold, sharp/dull), and others for vision, hearing, and other bodily functions. The nerves that are affected when you have ALS are the motor neurons that provide voluntary movements and muscle power. Examples of voluntary movements are your making the effort to reach for the phone or step off a curb; these actions are controlled by the muscles in the arms and legs.

The heart and the digestive system are also made of muscle but a different kind, and their movements are not under voluntary control. When your heart beats or a meal is digested, it all happens automatically. Therefore, the heart and digestive system are not involved in ALS. Breathing also may seem to be involuntary. Remember, though, while you cannot stop your heart, you can hold your breath-so be aware that ALS may eventually have an impact on breathing.

Although the cause of ALS is not completely understood, the recent years have brought a wealth of new scientific understanding regarding the physiology of this disease.

While there is not a cure or treatment today that halts or reverses ALS, there is one FDA approved drug, riluzole, that modestly slows the progression of ALS as well as several other drugs in clinical trials that hold promise.

Importantly, there are significant devices and therapies that can manage the symptoms of ALS that help people maintain as much independence as possible and prolong survival. It is important to remember that ALS is a quite variable disease; no two people will have the same journey or experiences. There are medically documented cases of people in whom ALS burns out, stops progressing or progresses at a very slow rate.
