内质网对包括膜的生物发生、囊泡运输和蛋白分泌在内的很多细胞功能都很关键，它是一个由管状结构构成的互联的网络，遍及真核细胞。这一特定结构的维持机制尚不清楚，尽管依赖于GTP水解的同型膜融合已知是内质网的生物发生和维持所必需的。现在，用果蝇所进行的一项研究表明，被称为Atlastin的一种GTP酶(在遗传性痉挛性截瘫中发生突变的人类Atlastin 1的一个同源分子)是同型膜融合所必需的，因而也是内质网形成所必需的。本段文字主要强调( )。

A．内质网的维持机制

B．Atlastin在内质网形成中的重要性

C．内质网对于细胞功能的重要作用

D．内质网的结构

任务型读写。
     阅读下面短文,根据所读内容在表格中的空白处填入恰当的单词,
每个空格只填一个单词.
     Many students eat their breakfasts on the way to school or in the dinning-room.  But some of them
don't really know how to eat well when eating out.
      Here is some important advice.  The first is to eat less fast food.  The most obvious harm of eating
too much fast food is weight gaining because of too much fat.  Young people and adults are at risk of
disease related to weight.  Too much fast food can drag your body down.  French fries, for example,
were recently found to contain much more acrylamide(丙烯酰胺) than other food.  This may cause
cancer.  Actually, deep fried food all contains acrylamide.  So don't eat it too often.
     Soda is another thing you should watch out for.  Cokes and other sodas contain a lot of sugar and
can slow down a person's calcium absorption, so it's best to drink as little soda as possible.
     Food in the dinning-room may not be as tasty as fast food, but it's actually easier to make healthy
choices.  Human bodies need variety.  You can have a dinner that balances lean proteins, vitamins and
complex carbohydrates(碳水化合物).  In other words, a meal with fish or meat, vegetables and some
bread or rice will provide you with most nutrients that the body needs.
     Some snacks, on the other hand, will help keep you going until your next big meal.  It is natural for
teenagers, especially boys, to feel hungry during school time.  Don't forget to take some foods, like
whole-grain biscuits or low-fat milk in your school bag.
