To help the environment, many Americans have made the change from paper and plastic bags to reusable grocery bags. But a report by a Florida newspaper says that reusable grocery bags sold by some supermarkets contain high levels of lead(铅). Lead is a metal that can be harmful to humans, especially young children, Now, Senator Charles Schumer is asking the US government to investigate(调查) the use of lead in reusable shopping bags.
“When our families go to the grocery store looking for safe and healthy foods to feed their kids, the last thing they should have to worry about is poisonous bags.” Schumer said, “A quick investigation will allow everyone to make informed, timely decisions.”  Schumer added.
Lead in the bags is not likely to rub off (因摩擦而粘在……上面)on food. But over time, paint on the bags can chip and the bags can wear out. When this happens, lead can be released(释放).
The Tampa Tribune newspaper said certain bags sold at Publix and Winn-Dixie supermarkets had lead levels that were a concern to health officials. The affected bags were found in Florida. But Publix has more than 1,000 stores in Alabama, Florida, Georgia, Sough Carolina and Tennessee. Publix says that all of its bags are under current laws about lead content, but that they have asked the makers of the bags to reduce the lead levels in the product.
The bags with the highest levels of lead had fancy designs and many pictures. Plain reusable bags without decoration were found to contain little lead. Consumers worried about lead levels in reusable bags can change to cloth or string bags. Paper bags are also a good choice, since paper can be recycled(回收).
Since 2007, Publix supermarkets have sold more than 13 million reusable bags. The store says because shoppers have made the change to reusable bags, it has saved more than 1 billion paper and plastics bags.
【小题1】 The shopping bags containing high levels of lead ______.

A．have been reported by a newspaper

B．have been stopped by the government

C．have stopped people from using reusable bags

D．have caused serious health damage to customers

【小题2】From Schumer’s words we can learn that ______.

A．reusable bags do little harm to kids’ health

B．people have shown much concern for the reusable bags

C．people will be informed of the facts about the reusable bags

D．people should refuse to buy things from supermarkets

【小题3】It can be inferred from the text that Publix might believe that the bags they sold are ______.

A．dependable

B．convenient

C．harmful

D．popular

【小题4】Customers are advised to choose bags ______.

A．with colorful designs	B．with fancy pictures
C．made of plastic	D．made of paper

An Experiment

Materials: Newspaper, ‘ACE’ hardware ruler (1/8 “think”), a flat table.

Purposes: We’ll show that there is air pressure pushing on us, from every direction while we’re on this Earth.

Procedure:

First put a thin ruler on a flat table with a little

less than half of it hanging off the edge of the table

(see the drawing below). Next place a sheet of newspaper

over the ruler flat against the table. Make sure to have

as little air as possible under the paper so that the fold line of the newspaper is at the ruler. Then quickly strike the end of the ruler hanging off the edge of the table. If you strike it quick enough, the ruler will break near the table edge.

What’s going on?

The Earth is covered in a layer of air that is nearly 80 miles thick and at sea level (the bottom) exerts or ‘pushes’ hard almost 15 pounds of pressure per square inch. That means that a full sheet of newspaper laid out flat has nearly 9,300 pounds of air above it.

When you break the ruler above, you are able to break it because of the 'heavy' air pushing down on the paper while you quickly strike the ruler. At first the table is pushing back on the paper, and if you move the ruler quick enough, other air around the edges of the paper can't get under the paper fast enough, so you are trying to lift that 9,300 pounds with the ruler! Some air gets under the paper, but not enough, so the ruler breaks.

1．By doing the experiment, we may realize         .

         A．that air exits everywhere

         B．why there are directions

         C．that we live with air pressure

         D．how air helps on the earth

2．How many steps are there in this experiment?          .

         A．2         B．3         C．4         D．5

3．The underlined word “exert” probably means       .

         A．cover completely                 B．advocate actively      

         C．influence gradually    D．press heavily

4．The ruler breaks under a quick strike mainly because of          .

         A．the air pressure on the newspaper  B．the heavy weight of the newspaper

         C．the heavy weight of the flat table     D．the strong power used on the ruler
