Ⅰ.单句语法填空
1．(2019·北京卷)Nervously facing challenges，I know I will whisper to myself (I) the two simple words “Be yourself”．
解析：考查反身代词。whisper to oneself为固定短语，表示“低声对自己说”，故填myself。
2．(2018·全国卷Ⅰ)If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give it/running a try.
解析：根据句意可知，此处表示“我们都应该尝试着跑跑步”，故填代词it，指代上文的running，此处也可直接填名词running。
3．(2018·全国卷Ⅲ)When the gorillas and I frightened each other, I was just glad to find them (they) alive.
解析：人称代词作宾语时，要用其宾格。空格前面是动词find，空格处应用宾格，故填them，指代上文的gorillas。
