It is believed that raisins (葡萄干) were discovered in the Middle East, where they were treasured. Any food that wouldn't spoil in the hot sun was very valuable. Prehistoric drawings in France show that raisins have been enjoyed in southern Europe for thousands of years. 1. In 1000 B.C. the Jews paid their taxes with raisins. Two jars of raisins in ancient Rome could buy one slave boy. 2.
In North America, the original mistake of leaving grapes to wither (枯萎) on the vine was not the only time raisins accidentally became popular. In the 1870s many people were growing grapes in California. 3. Most Americans had never heard of raisins at that time. In September, 1873 a severe heat wave struck the area. Before the growers could pick all their grapes, they withered on the vine. The grapes were lost. One grower took the dried grapes to a grocer in San Francisco. 4. The new accidental raisins grew into a major industry in California. Today almost all the raisins eaten in the United States are grown in California. California produces a third of the world's raisins.
5. Raisins also provide potassium, magnesium, calcium and certain B vitamins. Without added preservatives (防腐剂), raisins will stay fresh, delicious and nutritious if kept in a cool place. Raisins are tiny, portable and above all delicious.
A. They have been used for necklaces and as religious symbols.
B. Raisins are children's favorite snacks.
C. The grapes were either eaten as fresh fruit or were made into wine.
D. The grocer was unwilling to buy the dried grapes.
E. Raisins are high in iron, which is important to children's growing bodies.
F. Roman doctors believed raisins could cure anything from mushroom poisoning to old age.
G. The grocer's customers discovered that raisins made a delicious treat.
Blue Planet II's latest episode (情节) focuses on how plastic is having a destructive effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, oceans are drowning in plastic.
Though it seems that the world couldn't possibly function without plastics, plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s, the same decade that plastic packaging began gaining popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.
We put all these plastics into the environment, but we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.
And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning in the same breath as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don't have to remake our planet energy system.
This is not a problem where we don' t know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag-when taken collectively, these choices really do make a difference.

A.The plastics pollution research is too difficult.
B.Plastics have produced less pollution than coal.
C.Plastics have gained popularity too fast for science to catch up.
D.The world couldn't possibly function without plastics.
2.How did the author support his opinion in Paragraph 3?
A.By citing quotes from leading experts. B.By making a comparison and contrast.
C.By listing examples from his own experience. D.By presenting solid statistics.
3.What does the author intend to tell us in the last paragraph?
A.We reap what we sow. B.The shortest answer is doing.
C.All things are difficult before they are easy. D.Actions speak louder than words.
4.What is the main idea of the passage?
A.The oceans become choked with plastic. B.Ocean plastic is a global issue.
C.Blue Planet II has left viewers heartbroken. D.Plastics gain in popularity all over the world.
