Answer 1

分析 这个科学家很伤心．在她走回沙滩的时候，她很担心海洋生物．当她到达的时候，她看见一群当地的小学生正拿着垃圾袋收集塑料瓶．他们用了整整一个下午在清理沙滩．她很开心．当她跟老师交谈的时候，学生都围过来听．他们脸上洋溢着快乐，呼喊着："我们必须为保护环境做点儿事情！""很对！"科学家说，她脸上挂满了微笑．

解答 50．D 由后文的转折连词But可知，前后的内容是相反的，后面是让她感到惊喜的场景，因此可推知在去沙滩的路上，她心里很担忧，因此此处为worried about．
51．B 此处需表达的是看到前面的情景，科学家心里充满了快乐，需用到短语be filled with，因此答案为B．
52．A with后面加名词，表示伴随，smiles为名词，前面用形容词修饰，可知为A，A为形容词，bright．
53．C right为形容词，需由副词修饰，可推知为C或者E，一般不用E来修饰right，表达"很对"，可以用exactly修饰，故答案为C．
