People have believed for many centuries that animals can predict (预测) earthquakes. In fact, we can look back to a number of     1     (record) from the ancient Greeks (古希腊). They noticed that animals acted     2     (strange) in the hours before earthquakes. Even now people talk about dogs     3     won’t stop barking and cats going into hiding     4     an earthquake happens. Besides, strange behaviors (行为)     5     these aren’t limited to pets. People have also reported seeing chickens stop laying eggs, bees leaving     6     (they) beehives (蜂巢), and big groups of fish     7     (die) in the hours before a       8     (nature) disaster hits.

The     9     (true) is that we aren’t sure whether animals might be able to sense earthquakes before they happen. However, one thing is for sure that more research       10     (carry) out to find out the answer. Animals may be the key to predicting earthquakes before they happen and help save many lives. That’s what we want.

There was a serious rain in Henan in July, 2021. The rain caused floods in many areas. A lot of people suffered (受苦) by the flood. Then how can we protect     1     when there is a flood? The following tips may help you.

When you are at home, keep windows and doors closed and turn     2     the gas switches (开关). Get some food and swimming circles around you.     3     the rain water enters the room, immediately cut off the power supply to prevent the rain water from electrifying (电击) and wounding people.

If you are outside, do not stay under trees or large billboards (广告牌) close to power supply lines (电源线). The area above the second floor is     4     safer. And avoid standing on the bridges, especially on rivers. Floods in rivers may wash away bridges. In thunderstorm (雷雨) weather, it is better not to answer and dial mobile phones outdoors. The mobile phones can also cause thunder and hurt people. And you should leave the public transport facilities (设施) as soon as possible. Buses, subways, taxis and even high-speed railways may be stopped. Subways stopped underground and buses in low-lying areas are very     5    .

When you drive     6     rainy days, reduce (减少) the speed gradually (逐渐地) from     7     to low. When the streets are full of rain water, slow down your car and drive more     8    . If the vehicle stalls (熄火) in driving, get off the vehicle and wait for rescue. Never stay in the car all the time.
