问题    As someone who researches generational differences, I find one of the most frequent questions I’m asked is "What generation am I in?"
   If you were born before 1980, that’s a relatively easy question to answer: the Silent Generation【C1】______ born between 1925 and 1945; baby boomers were born between 1946 and 1964; Gen X followed (born between 1965 and 1979).
   Next【C2】______ millennials, born after 1980. But where do millennials end, and when does the next generation begin? Until recently, I (and many others) thought the last millennial birth year would be 1999 — today’s 18-year-olds.
   【C3】______, that changed a few years ago, when I started to【C4】______ big shifts in teens’ behavior and【C5】______ in the yearly surveys of 11 million young people that I analyze for my research. Around 2010, teens started to spend their time【C6】______ differently from the generations that【C7】______ them. Then, around 2012, sudden shifts in their psychological well-being began to appear. Together, these changes pointed to a generational cutoff around 1995, 【C8】______ meant that the kids of this new, post-millennial generation were already in college.
   These teens and young adults all have one thing in common: Their childhood or adolescence【C9】______ with the rise of the smartphone.
   A 2015 survey found that two out of three U.S. teens owned an iPhone. 【C10】______ this reason, I call them iGen, and as I explain in my new book "iGen: Why Today’s Super-Connected Kids are Growing up Less Rebellious, More Tolerant, Less Happy — and Completely Unprepared for Adulthood", they’re the first generation to spend their adolescence with a smartphone.
   What makes iGen different? Growing up with a smartphone has【C11】______ nearly every aspect of their lives. They spend so much time【C12】______ the internet, texting friends and on social media — in the large surveys I analyzed for the book, an average of about six hours per day — that they have less leisure time for【C13】______ else.
   That includes【C14】______ was once the favorite activity of most teens: 【C15】_____with their friends. Whether it’s going to parties, shopping at the mall, watching movies or aimlessly【C16】______ around, iGen teens are participating in these social activities at a【C17】______ lower rate than their millennial predecessors.
   iGen shows another pronounced break with millennials: Depression, anxiety, and loneliness have shot【C18】______ since 2012, with happiness declining.
   The teen suicide rate increased【C19】______ more than 50 percent, 【C20】______ did the number of teens with clinical-level depression. [br] 【C19】
选项 A、at
B、to
C、by
D、for
答案 C
解析 此处考查介词by的用法。百分比前面用介词by表示“增加了”，用to表示“增加到”。这句话的意思是：青少年的自杀率增加了50％以上。自杀率不可能增加到50％，所以C为正确选项。
