3 . The milk carton, made from layers of paperboard and plastic first, appeared in 1952 and soon replaced glass bottles. They were far lighter, could be piled and distributed more easily, and more significantly, they were found to have 78 percent less of an impact on the climate than glass bottles. The Tetra Pak cartons, with a layer of aluminum foil(铝箔) that allowed heat –treated milk to remain fresh, followed in 1961.

However, every technology has drawbacks and those of plastics are becoming painfully obvious. Landfills are stuffed with bottles and cartons, and trillions of pieces of plastic float in the world's oceans.

Carton makers are far from the only contributions to the ballooning volumes of packaging waste. In some ways, they're encouraging recycling. However, it is not universal even in Europe, only 47 percent of materials from the 37 billion cartons, made for European countries in 2016 were recycled.

Cartons are also stuck in a broader paradox(悖论): as economy advances, people tend not only to recycle more but also to consume more. Croatia’s overall recycling rate for packaging in 2016 was 55 percent, compared with Germany’s 71 percent, but the average German produced four times as much packaging waste as the average Croatian.

In theory, cartons are fairly recyclable. When pulped （打成浆） in liquid, their various layers are separated into paper, plastic and metal. All of them can then be turned to other uses. In practice, recycling is currently unfeasible for cartoons, because a cotton is carefully bonded and constructed often with a plastic lid and a straw fixed to the side.

This means carton makers need to do more to make their products not only useful but also sustainable. This involves stronger links with recycling factories and waste companies to ensure that containers they pump into the world are returned and reused. In the long term, they face a huge technological challenge to get to what Tetra Pak says is its ultimate aim -- to construct cartons entirely out of renewable materials.

4 . Lead has proved to be a useful metal.     1     It goes into car batteries and also helps make bright pigments, used to paint walls, metal work and toys.

    2     In the worst cases it causes comas（昏迷）and death. More often its effects are slow but harmful. Research shows that lead is a threat to little babies, who are most likely to take in dust and paint chips that contain lead. Their brains can be easily harmed.     3    

The dangers of lead have long been known. American banned it from paint 40 years ago, and by the late 1990s leaded petrol had been stopped gradually in almost all rich countries. But the effects continue to exist.     4     The situation is more alarming in the poor world, where the use of lead-based paints is spreading. As people in Asia and Africa become richer, they start to decorate their homes, but the paint they use, even from pots labeled "lead-free" often contains it.

It is neither difficult nor expensive to stop using lead.     5     And industrial use is no exception, because the contamination （污染物）spreads and industrial paint inevitably finds its way into the consumer market. Yet only four sub-Saharan African countries have formally placed bans and local factories are often unaware of the harm that lead causes.

A．Yet lead is also a poison.

B．It turns up everywhere.

C．All countries should ban lead in paint.

D．Half a million American children are diagnosed with lead poisoning.

E．There is no excuse for poor countries to repeat the mistake of rich ones.

F．Taking some simple precautions can help protect you and your family from lead exposure.

G．But only years after exposure are the results apparent in lower IQ and learning disabilities.
