【分析】
本题为英语词汇适当形式填空题,需结合句子结构、语法规则及固定搭配变形:1. 定冠词the后需接名词,所给词different为形容词,需转换为名词且用复数;2. 由并列结构的more可知,需用little的比较级;3. many后接可数名词复数,similar需转换为名词复数;4. 数词800后接可数名词复数;5. 涉及固定搭配expect sb to do sth。
【解析】
1. 定冠词the后接名词,different的名词形式为difference,此处指两个婴儿间的差异,应用复数,故填differences;
2. 由后文的more可知,此处需用little的比较级less,对应“更少的垃圾食品”,故填less;
3. many修饰可数名词复数,similar的名词形式为similarity,此处表示“相似点”,应用复数,故填similarities;
4. 数词800后需接可数名词复数,metre的复数为metres,故填metres;
5. 固定搭配expect sb to do sth(期望某人做某事),此处需用动词不定式,故填to exercise。
【答案】
1. differences 2. less 3. similarities 4. metres 5. to exercise
