Students can easily create sandstorms for the science project. Place a little flour（面粉）in a clear plastic box with a hole at one end. Blow into the hole gently to get the flour to fly off the surface of the box. The flour may stay in the air for a long period of time. The more flour you blow into the air, the longer time it will take for all the particles（颗粒）to fall down. The same happens in dust storms or sandstorms. Another experiment is to take a glass of water and place a few drops of milk into the water. The milk will separate as it makes its way to the bottom of the glass. The milk will stand for sand moving through the atmosphere. 

The deserts of the world are always producing sandstorms. You can keep track of these storms and make storm predictions using the NTOMS which tracks dust and smoke patterns worldwide. For the project, the students can help predict the sandstorm patterns and how the dust from the storm will travel. Choose a place, such as the Sahara, and track the dust as it reaches the Caribbean or even the United States. 

Depending on the area, a student may be able to collect dust from another continent（大陆）. Use the Naval Website to track sandstorms in your area. Place a piece of glass outside to collect dust and other particles from the air. One should place the glass in areas off the ground, such as on an outdoor table, to protect it from being stepped on and broken. Watch the particles carefully under a microscope（显微镜）and study the difference between sand particles and dust ones. Sand particles will have sharper, clearer edges under the microscope.

 

1. What's the usage（用处）of flour in the experiment?

A. To clean a plastic box easily.

B. To show how the sandstorm comes into being（形成）.

C. To find out how long it stays in the air.

D. To blow it into the box through a hole.

2. The underlined word “it” in the first paragraph refers to “____________”.

A. experiment B. water

C. milk D. glass

3. From the passage, we can know that the NTOMS can_____________.

A. produce sandstorm in the deserts

B. watch the movements of dust

C. predict what the weather is like

D. prevent the sandstorm happening

4. Which of the following is the best title for this passage?

A. Making a table top sandstorm

B. Producing sandstorms in the deserts

C. Sandstorms making for students

D. Sandstorm projects for students

 

【答案】1. B 2. C 3. B 4. D

【解析】本文介绍了学生可以做的有关沙尘暴的研究实验，通过相关的技术和系统，学生们可以帮助预测沙尘暴的模式以及来自沙尘暴的灰尘将如何传播。

1. 推理判断题。根据“Place a little flour（面粉）in a clear plastic box with a hole at one end. Blow into the hole gently to get the flour to fly off the surface of the box...The same happens in dust storms or sandstorms”，可知，通过做面粉的这个实验，了解到沙尘暴是如何形成的，故选B。

2. 词义猜测题。根据“The milk will separate as it makes its way to the bottom of the glass”，可知，当牛奶进入玻璃杯底部时，它会分离，所以it指代“milk”，故选C。

3. 推理判断题。根据“You can keep track of these storms and make storm predictions using the NTOMS which tracks dust and smoke patterns worldwide”，可知，NTOMS可以追踪世界范围内的沙尘和烟雾模式，即注意沙尘的运动轨迹，故选B。

4. 最佳标题。通读全文可知，本文介绍了学生可以做的有关沙尘暴的研究实验，故选D。
