试题分析:本文主要叙述了保护视力的重要性以及保护视力的几个具体方法。
【1】B本段的标题是Schedule yearly exams安排每年都检查眼睛。横线下一句:Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check.可知专家建议父母亲在6-12个月的时候就带着孩子去进行眼部检查。也就说眼部检查要尽可能地早进行。故B正确。
【2】C长时间地在强烈的阳光下,都会伤害到我们的眼睛。所以不管是什么季节,我们都要佩戴太阳镜,因为太阳镜可能会保护我们的视力。故C项符合上下文串联。
【3】G本段的标题是Give your eyes a break.让眼睛休息。本段第一句三分之二的美国人花7个小时的时间使用电脑或者电子产品。没有让我们的眼睛得到休息,这样频繁地使用会增加我们眼睛疲劳的危险。故G项符合上下文串联。
【4】A [来源根据本段第一句As part of a healthy diet, eat more fruits and vegetables each day.可知要多吃蔬菜等绿色食品,对我们的眼睛是有好处的。故A项符合段落大意。
【5】F很多人都佩戴隐形眼镜等,但是在使用中总是没有按照使用说明,这也让他们的眼睛处于危险之中。那么我们要采纳医生的建议,合理使用这些设备。故F项符合上下文。
【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Winter begins in the north on December 22nd.People and animals have been doing what they always do to prepare for the colder months, Sqzeirrels, for example, have been busy gathering nuts from trees.【1】They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut(黑胡桃)trees【2】The black walnut tree is also a central part of some hardwood forests.Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student nowat the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels.Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places.【3】So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring.Red squirrels, however, store large groups of nuts above ground.【4】But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century. The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade(涌入)Indiana.【5】
