one language”. Some take on the task of learning a second language alongside their children. 36 Depending on your home situation, this can require a lot of planning, effort and persistence (坚持) on your part. You’d better use all of the resources at hand. While having back-and-forth conversations with native speakers is the most effective, there are lots of other ways. 37 Watching a favorite show or reading an interesting book in the non-dominant (非主导的) language can make learning enjoyable. You may also find
classes and schools that teach in the language you want your children to learn.
38 Travel is one way to engage your kid in everyday situations that are meaningful and real. Exposure to the language in its real context can significantly boost a child’s interest in and understanding of the language. But time abroad is not a requirement for real interactions. 39 For example, your son can use Spanish when playing with his Spanish-speaking cousins.
While you can always change the language learning plan if the path you’re on isn’t working, you shouldn’t get too discouraged when things aren’t happening as quickly as you might expect. 40 Language learning is a progressive and long-lasting process, and breakthroughs may come in unexpected ways and at different times for each individual.
Know there’s a lot happening under the surface.
Provide authentic opportunities for speaking practice. C．Individuals have different levels of fluency in each language.
D．Introduce TV programs, songs and books in both languages to children. E．And others use a mix of strategies to expose their kids to both languages.

【解析】解：时间内，三个物体的位移与时间均相等，则三物体的平均速度相等，故A错误；
B.根据题意，由运动学公式，整理可得，结合图像可得，，汽车停下来的时间，经过3s汽车的位移为，故B正确；
C.根据加速度的定义式有，则有可知，丙图中阴影面积表示时间内物体的速度变化量，故C错误；
D.物体做匀加速直线运动，根据位移公式有，变形可得，结合图像则有，解得，故D错误。
故选：B。
甲图中，分析时间内三物体的位移关系，再判断平均速度关系；乙图中，根据位移一时间公式求位移大小；丙图中，图线与时间轴所围的面积表示速度变化量；丁图中，根据变形得到与t的关系式，结合图像的斜率求加速度大小。
对于图像问题，关键是能够根据已知的公式推导出纵坐标与横坐标的关系式，分析图像的斜率、截距、面积等方面的意义，然后作出正确的判断。
