小李与小王同学帮助实验老师整理化学药品时，发现分别放在两个试剂瓶中的两片用砂纸磨得光亮的银白色金属未贴标签．到底它们是哪种金属？两位同学首先对这两种金属X和Y的金属活动性顺序进行实验探究．

（1）进行猜想：

1小李猜想：活动性X大于Y．

2小王同学猜想：活动性Y大于X．

（2）设计实验方案，进行实验、获得知识．完成如下实验报告，并回答下列问题：

①实验步骤	②实验现象	③结论
_________________________ _________________________ _________________________ _________________________ _________________________	金属Y表面无明显变化，金属X的表面有气泡冒出． 将燃着的木条放在装金属X的试管口，气体燃烧．	_________________________ _________________________ 小王的猜想：（填“正确”或“不正确”）

（3）上述实验之前，实验老师只知道X、Y是银、铁中的一种，则根据实验结果说明Y就是______．实验室急需一定量的Y粉末，小李认为可用现有的X金属粉末和Y的盐溶液、蒸馏水等药品，配以必要的仪器来制得急需的Y粉末，原因是（用反应的化学方程式表示）：______．

     The survey showed that the top choice for both parents and teens was to go out for a family meal. This is

ideal for those who don't have much time to spare because the occasion can be made to feel special while the

whole family can stay together for a couple of hours or less. Make sure that everyone has a say in where they'd

like to eat. In case you don't go to one person's suggested restaurant this time then avoid disputes by suggesting

you to there another day.

     The second favorite choice for spending quality time was to go on a family holiday. This can be one of the

most effective ways to engage with your teen in a fun and relaxing setting away from the distractions (使人分

心的事) of normal daily life. What's more, you'll return home with shared memories to cherish forever.

     If you're looking for something slightly less expensive and time-consuming than a holiday, plan a day trip

instead. Day trips were considered by more teenagers than parents. in the survey as a good way to spend quality

time. Unsurprisingly, more teens than parents also said that they'd like to go to a theme park. But if the thought

of roller coasters and long queues leaves you feeling uncomfortable, perhaps consider a day out to another town

or city, going shopping or catching a movie at the cinema instead.

     If you've got a sporty teen, try taking part in physical activity with him. Whatever it takes to get your blood

pumping, having fun will be well worth it. Although if you're rather athletically challenged, try something a bit

more sedate, like bowling (保龄球). Also, energetic and curious teens often enjoy outdoor activities, such as

camping, so why not put yourself to the challenge and see where the spirit of adventure takes you both?

     But don't worry if the thought of such exertion (努力) makes either of you break out in a cold sweat. Time

spent one-on-one at home just enjoying each other's company can be equally-if not more-valuable as any other.
