From the time each of my children started school, I packed their lunches. And in each lunch I packed, I included a note. Often written on a piece of small paper, it might be a thank-you for an unusual moment, a reminder of something we were happily expecting, or a bit of encouragement for the coming test or sporting event.

    In early grade school they loved their notes. But as children grow older they become self-conscious（有自我意识的）, and by the time he reached high school, my older son, Marc, informed me he no longer enjoyed my daily notes. Telling him that he no longer needed to read them but I still needed to write them, I continued until the day he graduated.

    Six years after high school graduation, Marc called and asked if he could move home for a couple of months. He had spent those years well, graduation from college, completing two internship（实习）in Washington, D.C., and finally, becoming a technical assistant in Sacramento. However, he had lived away from home except for short holiday visits. With his younger sister leaving for college, I was especially happy to have Marc back. Since I was still making lunch for his younger brother, I packed one of Marc, too. Imagine my surprise when I got a call from my 24-year-old son, asking about his lunch.

    “Did I do something wrong? Don't you love me any longer, Mom?” he asked.

    “Of course I love you, dear!” I laughingly said. “What's wrong?”

    “My note, Mom,” he answered. “Where's my note?”

    With air pollution making much difference to many of Chinese cities, parents are calling for the installation(安装) of air cleaners in classrooms. There has been much debate over whether air cleaners should be used in China's schools. Some parents have donated cleaners to their children's classrooms, while others raise money together to make the purchase(购买). “Our school bought air cleaners last year. We did a little fund raising, with each parent throwing in several hundred for that,” said one parent.

    However, the idea of installing air cleaners for all the classes has been refused by some schools. Liu Liangcheng, vice-principal of Beijing's Taipinglu Primary School, says installing air cleaners bought by parents may lead to problems. “We have refused air cleaners bought by parents before, as there are clear and strict rules against educational fees. We can't just break the rules here. And without standard guidance (指示) from local authorities(权威部门), it is hard to decide on the brand of the cleaner, installation and even safety of the device(设备).”

    Moreover, experts say air cleaners can cause other health problems. Deng Gaofeng who works for the China Academy of Building Research says. “ In the classroom, if we keep windows and doors closed, the concentrations (浓度) of CO₂ will double from 1,000 PPM to some 2,000 PPM. According to national safety standards, the highest level should not be more than 1,500.” In addition, experts say air cleaners on the market are mostly designed for homes or offices. Evaluation(评估) is needed to know whether they are suitable in classrooms.

    It seems whether air cleaners should enter China's schools is an ongoing question. It still requires a more detailed plan.

    Read the passage carefully and answer the questions according what you've read.

    The Book Thief was written by the Australian author Markus Zusak and it has been his most popular work. Published (出版) in 2005, it has become an international bestseller and been translated into several languages. In 2013, it was adapted into a film of the same name.

    Are you wondering who the“book thief”is? It was Liesel Meminger, a 12-year-old girl living in Germany during World War II. While the Nazis were creating horrors (恐怖) all around, Liesel came across something that she couldn't give up: books. She stole books that belonged to the mayor's (市长的) wife, as well as books that the Nazis wanted to destroy.

    A Jewish man named Max inspired Liesel's love for books. Liesel's family hides Max in their house. He developed a close relationship with Liesel and taught her to read in secret. Soon, Liesel realized the power of words. She not only stole books, but also wrote her own stories.

    “It is not the kind of story that has you crying one moment and laughing the next,” as The Guardian reported. Instead, the sadness of Liesel's story interests you. It makes you realize that such kinds of things have happened to many other people. And it makes you think a lot.
