The thought of a natural disaster can be【小题1】(frighten). But you can prepare your family for it with some simple steps. Below are some common【小题2】(measure) of preparing for disasters.

Have enough ways to get warnings. There【小题3】(be) different ways to receive a warning of a disaster. The common ones include using the television, phone, etc. To avoid missing the warning, you’d better make sure you have at least three ways to receive the warning.

Decide how to make family members communicate. Come up with【小题4】communication plan in case you are【小题5】(separate) in a disaster. Provide each member of the family with a phone, for example. And make a contact card for each family member so they have the phone numbers and addresses【小题6】they may need.

Choose【小题7】least two meeting places. Do it in case all of your family members can’t   reach a designed meeting place. Choose one place in your neighborhood or close to your home as well as one that’s out of town. Consider【小题8】(meet) at the closer place first in a disaster. And keep the out-of-town place as a backup.

Run practice drills (演习). It’s important【小题9】(practice) what to do in case of a natural disaster,【小题10】(especial) if you have children. Each year, you’d better organize a practice drill for a possible disaster. And try to let all the family members take part in it.

The National Weather Service (NWS) reported that the Tittabawassee River was at least ten 【小题1】 (foot) above flood level, and still rising. Under the growing pressure of the water, the Edenville dam and the Sanford dam broke on 19, May, 2020.

The flooding has covered many roads and bridges in Midland County. For 【小题2】( safe) , so far the Michigan National Guard 【小题3】( help) in moving around 11,000 people in the nearby towns of Edenville, Sanford, and Midland from their homes.

Midland is home to the Dow Chemical Company, 【小题4】 raises other worries. The company has large chemical tanks in Midland which, if【小题5】(flood),could release(释放)dangerous chemicals into the river.       

For decades, Dow released dangerous chemical pollution into the Tittabawassee River.【小题6】a result, there is an area farther downstream that is【小题7】(heavy) polluted. The chemicals there have settled into the mud on the river bottom and in the areas along the river. The area was supposed【小题8】 (clean) up next year. Now there are concerns that the strong flood waters could make the【小题9】(harm) chemicals come out and release them back into the river. This could cause serious problems, and would make any cleanup far 【小题10】difficult.

A desert doesn’t sound like the most promising place to plant a tree. Yet, since 1978, China【小题1】 (plant) at least 66 billion of them across its desert northern territories, hoping to transform its sandy dry land and yellow dunes 【小题2】 a Great Green Wall.

Ian Teh 【小题3】(record) this amazing undertaking while traveling through northern China last year. His expansive photographs show workers tending young trees, blasting them with water and 【小题4】(fill) irrigation tanks. “Planting trees sounds great on paper, 【小题5】 you can feel doubtful,” Teh says. “But when seeing in person, it was impressive.”

The tree-planting strategy is a massive attempt to help fight desertification. 【小题6】 (rough) a million square miles of China—a quarter of the country—【小题7】(cover) in sand. Drought, deforestation, overgrazing and other【小题8】 (problem) threaten an additional 115,000 square miles, fueling very cruel and 【小题9】(violence) sandstorms that regularly blast cities like Beijing and Dunhuang. Many scientists are feeling doubt that planting trees will make a difference in 【小题10】 long run. But China’s State Forestry Administration claims the measure has reduced sandstorms by 20 percent and desertification by nearly 5,000 miles in recent years.
