- BCan changing battery materials solve the serious safety problem?正解
- CCan applying reused materials arouse people’s safety awareness?
- DCan reorganizing the application materials help pass the safety review?
04According to the video, the innovations of the aluminum battery made by Dr. Yang and his team are turning heads around the globe. What does the phrase “turning heads around the globe” mean?
- ADr. Yang and his team are turning their heads and circling a globe.
- BThe innovations of the aluminum battery scare people away.
- CThe battery is too big to move on to the stage, so people cannot see it.
- DTheir surprising results capture people's attention around the world.正解
05A battery is made of four key components: an anode, electrolyte, separator, and a cathode. The anode and cathode exchange ions via liquid electrolyte, generating electricity.

06After watching the video, Cathy wants to share what she just learned with her friends. However, she cannot recall this part. Please help her fill in the blanks.The Industrial Technology Research Institute invented aluminum batteries for three reasons. Number one, to use renewable energies to prevent the worsening of ______________. Number two, renewable energies are ______________. As a result, storage methods are necessary. Number three, because of the design of existing batteries, the cost of using renewable energy is extremely ______________. Moreover, some existing batteries are toxic or pose safety concerns.
- Aglobal warming / unstable / high正解
- Beconomic recession / steady / expensive
- Cglobal warming / stable / high
- Deconomic recession / unsteady / cheap
07Which sentence best describes the picture?
- ABefore people use the aluminum battery, it needs to be cut open first.
- BAlthough the aluminum battery is cut open, it can even keep running without safety concerns.正解
- CWhen using the aluminum battery, we need to wear rubber gloves due to its toxicity.
- DBefore getting rid of the aluminum battery, we need to cut it open and pour out the contents.
08Aluminum batteries can recharge rapidly. Because they are produced by pairing up a graphitic-foam cathode with an aluminum anode, they can be charged in 60 seconds. This discovery opens up a world of possibilities for batteries.
- ○正解
- ╳
09The production cost of aluminum batteries was very high in the early stage of their development, so mass production was impossible. However, after Dr. Yang’s team started to produce some of the electrolytes themselves, they markedly reduced the production cost. As a result, aluminum batteries have become fairly price-competitive compared to lithium batteries.
- ○正解
- ╳
10Aluminum batteries are not recyclable and toxic. This is because they are made of aluminum. There is scarce aluminum on earth, and it cannot be recycled and reused. Moreover, aluminum is a toxic material. Therefore, using aluminum batteries is not a good way.
