A constantly doing memory work
B making frequent adjustments
C going through specific training
D taking part in various mental activities
注:考第三段末句。
Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. The idea is not necessarily to learn to memorize enormous amounts of information, says James Fozard, associate director of the National Institute on Aging. Most of us dont need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness. Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
23. The findings of James and other scientists in their work _________.
A remain a theory to be further proved
B have been challenged by many other experts
C are practised by the researchers themselves
D have been generally accepted
注:第三段首句中的theory等同于findings。
原来我们的海洋是这样的,我们的海鸥是这样的,我们的生活却是这样的蓝天,白云,碧海以及划过天际的白色海员——海鸥。
是什么让海水不再蓝,是什么让海鸥不再起飞?那是我们人类的创作啊??!贪婪的人们为了自己的利益,透支着美好的未来,破坏着环境。殊不知,我们的环境是如此的脆弱,经不起再多的摧毁。当黑色的石油遍布海洋,腐蚀着各种生物,生活失去了原有的颜色,这难道就是我们的环境吗?这就是我们想要的未来吗?
“东方”替我们践行着环保的理念,用着过激行为保护这环境,却被人们所不接受。这难道还不难引起世界上每个人的深思吗?试想:如果我们每个人能够在生活中,尽自己的能力去多做一点,我们的生活难道不会更好吗?答案毋庸置疑,为什么不拯救一下频临灭绝的生物,改善一下我们生活的环境,更重要的是拯救我们人类自己,打造一个美好的未来。
每个人都要加入到环保行动中,加大环保的宣传,加强环保的意识,为身边的人树立一个好榜样,让灵魂更加的高尚。社会上此时此刻还在制造污染,破坏环境的企业,请睁大眼睛,看看你头顶的'蓝天,深吸一下空气,但愿那些遭受毒手的生物能够唤醒你们的良知。自以为高明的掩饰这些破坏环境的行为,在别人眼里,在你的心里,都清如明镜。 让天更蓝一点,水更清一点,树更绿一点,世界更美一点。大家行动起来吧,我们的家园就只有一个,仅仅一个而已,我们伤不起,也不
能够伤害。每人付出一点点,就会有一个美丽的家园,也会有一个个美丽的笑容。
