第4课时　Assessing Your Progress & Video Time 　[见学生用书P27] Ⅰ.阅读理解 A Healthy，shiny hair is an attainable goal for many people.What you eat can bring luster and strength back to your hair.A balanced diet filled with so­called superfoods like certain fruits and oils treats your hair from the inside out. Oils The omega­3 fatty acids in eggs，walnuts，and fatty fish like salmon help make hair shiny.These oils can also be obtained through some vegetable oils or flaxseed(亚麻籽)oil，but are found in higher amounts in oily fish and eggs.The protein in these foods also helps hair grow strong and healthy.Also found in eggs are B12 and biotin，both of which are essential for healthy skin，nails，and hair. Avocado Avocados contain high amounts of vitamin E．Only 2 ounce of a medium­size avocado contains 8 percent of your daily recommended intake of vitamin E．If you don't like to actually eat avocado，you can make an avocado mask to put on your hair.Vitamin E helps to keep your hair colour bright and prevents split ends. Coconut Oil The medium­chain fatty acids in coconut oil are used differently by your body than other saturated fats.An added benefit of coconut oil is its ability to make your hair shiny and healthy.Use coconut oil to cook your chicken or seafood，add it to your salad，or put it directly on your hair as a mask.Coconut oil's anti­fungal agents also help protect against and treat dandruff and other scalp problems. Vitamin C Fruits Fruits high in vitamin C，such as oranges，peaches，pineapples，strawberries，and kiwi—help maintain healthy hair and fight against free­radical damage from the environment to protect your hair against pollutants.Make sure to eat lots of fruits high in vitamin C．You can also apply the juices of these fruits directly to your hair by mixing it into your shampoo. 语篇解读：本文是一篇应用文。文章主要介绍了四种对头发有好处的物质，文章还介绍了获取这些物质的方式以及使用方法等信息。 (　B　)1.According to the passage，eggs contain a lot of essential nutrients needed by healthy hair EXCEPT ______.
