一、语法填空常考点
1．(2021·浙江1月高考)In a study of 33 years of trends in Body Mass Index(体重指数)across 200 countries, the scientists found that people worldwide are getting heavier and that most of the rise is due to gains in BMI in rural areas.
2．(2020·新高考全国卷Ⅰ)They kept their collection at home until it got too big until they died, and then it was given to a museum.
解析：or 根据句意“他们把收藏品保存在家中直到收藏数量过大或者他们去世”可知，应填入表示选择关系的并列连词or。
3．(2019·全国卷Ⅱ)I work not because I have to, because I want to.
解析：but 句意：我工作不是因为我不得不工作，而是因为我想要工作。not ...but ...为固定结构，表示“不是……而是……”。
4．(2016·四川高考)It was time for her to have a new baby, it was also time for the young panda to be independent.
解析：and 根据语境可知，“It was time for ...”和“it was also time for ...”之间是并列关系，故用and连接。
