The plants grown by Wageningen University researchers in Mars-like soil back in March have been analyzed and the results are excellent: at least four of the crops do not contain harmful heavy metal levels and are perfectly safe to eat, the University researchers report.

If you’ve seen The Martian, you can remember how much Matt Damon got done living off of his poo-powered crop of potatoes. It just goes to show how important it is for a long-term colony to be able to grow their own food locally. We’ve taken one step closer to that goal in March, when Netherlands’ Wageningen University reported that they’ve managed to grow ten different crops in Mars-like soil.

However, growing food doesn’t do us much good if eating it kills us, and researchers were worried that these crops contained dangerous heavy metals like lead or cadmium(镉) from the martian soil. But future colonists are delighted, as lab analysis of the crops determined that at least four of them are safe to eat.

Led by ecologist Wieger Wamelink, the team tested radishes, tomatoes, rye, and peas. They looked at cadmium, lead, aluminium(铝), nickel(镍), copper, chrome(铬), iron, arsenic(砷), manganese(锰), and zinc(锌) contents in the plants, and didn’t find any in dangerous levels. In fact, some of these vegetables have lower levels of heavy metals than those grown in regular potting soil. The plants were also tested for vitamins, alkaloids(生物碱), and flavonoids(类黄酮), with good results. While there are six more crops to test, Wamelink himself said that the results up to now are “very promising.”

“Growing food locally is especially important to our mission of permanent settlement, as we have to ensure sustainable food production on Mars. The results of Dr. Wamelink and his team at Wageningen University & Research are significant progress towards that goal,” said Mars One co-founder and CEO Bas Lansdorp in a press release.

A crowdfunding campaign is underway (and will be until the end of August) to fund the test of the remaining crops, potatoes included. If all the crops test out safe, with concentrations of heavy metal the FDA and the Dutch Food Agency consider as safe, Wamelink’s team will host a “Martian dinner” at the Wageningen greenhouse.

But I’ve seen the movie. Stay clear of the potatoes.

1.Which of the following is true according to the passage?

A. Four crops grown in martian soil have been tested safe to eat, with no heavy metals in.

B. The ability to grow food locally can ensure the permanent stay on Mars.

C. The team temporarily lack money to test the remaining six crops.

D. A “Martian dinner” will be hosted after all the remaining crops have been tested.

2.What is Bas Lansdorp’s attitude towards the research results?

A. Neutral.        B. Indifferent.        C. Unfavorable.        D. Praiseful.

3.The author writes the passage in order to _________.

A. prove that it is practical to grow crops on Mars in the future

B. show crops grown in martian soil are safe for people to eat

C. point out the importance of growing food locally for long-term settlement

D. report the recent research findings of the possibility of growing food on Mars

While bees hopping from one flower to another is vivid to watch, having bees disturbing a backyard barbecue certainly isn’t. They may seem like pesky creatures to get rid of, but there are quite a few things you may not know about bees, especially the impact they have on our livelihood.

The main purpose of bees, particularly honey bees, is to help pollinate the plants around them. According to the Department of Entomology at Pennsylvania State University, pollinators (such as bees) help to fertilize plants, which results in “the formation of seeds and the fruit surrounding seeds”. Pollinators are necessary for three-quarters of our major food crops, including fruits, vegetables, and nuts. An estimated 300,000 species of plants need pollinators. That’s around 80 to 95 percent of plant species. Without pollinators, the number of crops we have will take a serious hit.

Other pollinators can help out with this process including butterflies, beetles, and flies. Even some birds and bats can be pollinators. However, bees of various species are known for being natural pollinators for plants.

Unfortunately, for years there has been an alarming decline of bees around the globe. The University of Vermont published a study stating that 23 percent of the wild bee population declined between 2008 and 2013. 139 counties in parts of California, the Pacific Northwest, the Midwest, west Texas and the Mississippi River valley have taken the worst hit in wild bee declines. Since 39 percent of U.S. croplands rely on pollinators for their crop including those beloved apple orchards and pumpkin patches in the fall, we are facing a serious threat.

By taking care of the bees, our world is able to benefit in terms of agricultural income and nutritious food supply. You may not be able to make a huge change on an industrial level, but as someone with a landscape of your own, why not help save the bees?

1.What is the best title for the passage?

A.Bees Is Disappearing?

B.How You Can Save Bees?

C.How Bees Help Pollinate the Plants?

D.Why You Shouldn’t Kill Bees in Your Yard?

2.What is the main purpose of bees?

A.To provide delicious honey.

B.To disturb backyard barbecue.

C.To get rid of some pesky creatures.

D.To help pollinate the plants around them.

3.Why does the author list the numbers in Paragraph 2?

A.To show the diversity of plant species.

B.To show how we depend on plants.

C.To prove the importance of pollinators such as bees.

D.To make a comparison between plants which need pollinators and which don’t.

4.Why does the author say “we are facing a serious threat”?

A.Because the bee population has decreased sharply.

B.Because lots of wild bees have been hit by people.

C.Because many people are attacked by wild bees.

D.Because the croplands have produced less crops in the fall.

In the reign of Queen Elizabeth, two plants were brought to England, for the first time, by Sir Walter Raleigh, both of which are now very much used—the tobacco-plant and the potato. Sir Walter had sailed across the seas to America, in search of new lands; and he brought back both these plants with him.

When he was in America, he had seen the Indians smoke, and before long he acquired the habit himself. He became extremely fond of smoking, and frequently indulged in the practice.

When he returned to England, he was sitting by the fire one day, and began to smoke. In the middle of his smoking, the door opened, and in came his man-servant. Now this man had never in his life seen any one smoke, and did not know that where was such a plant as tobacco. So, when he saw the smoke coming from his master’s mouth, he thought that he was on fire!

But very soon the old servant got used to seeing people with smoke coming out of their mouths; and all the young nobles of the court began to smoke because Sir Walter did so.

At first, people did not like the potato at all: nobody would eat it. Yet Sir Walter told them how useful it would be. The potato, he said, could be made to grow in England. He told them that, when the corn-harvest failed—which it often used to do—people need not starve if they had plenty of potatoes.

Queen Elizabeth, who was a very clever woman, listened to what Sir Walter said, and had potatoes served up at her own table. There the grand people who dined with her majesty were obliged to eat them. But they spread a report that the potato was poisonous, because it belongs to the same order as the deadly nightshade(龙葵属植物) and many other poisonous plants. So, in spite of all that the Queen could do, no one would eat potatoes, and they were left for the pigs.

The people did not find out their mistake till many years afterwards when the French king Louis XVI asked his people to eat them. And people began to find out how good and wholesome they were. The potato was more and more liked; and now there is hardly any vegetable that is more highly esteemed.

1.What do we know about Sir Walter?

A.He introduced the tobacco-plant and the potato to England.

B.He went to America in order to do research on plants and animals.

C.He was forced to smoke by the Indians in America during his stay there.

2.People were afraid of the potatoes at first because ___________.

A.the Queen refused to eat them herself

B.they were used as poison by the Indians

C.they were long used as food for the pigs

D.they belong to the poisonous nightshade

3.What can we learn from the text?

A.Both the tobacco plant and the potato were native to France.

B.Young nobles in England refused to smoke for the terrible smell.

C.It was not easy to grow corn back in the age of Queen Elizabeth.

D.The English people were the first to accept potatoes as tasty food.

4.What conclusion can we draw from the two stories?

A.Only those who are willing to take risks can succeed in the end.

B.They are lots of new plants on the earth that can be used as food.

C.All people are afraid to try things that are new and strange to them.

D.The upper class had huge influence on the way people lived in the past.

Genetic modification (基因改良) dates back to ancient times, when humans influenced genetics by selectively breeding organisms (培育生物) according to an article by Gabriel Rangel, a public health scientist at Harvard University. When repeated over several generations, this process leads to great changes in the organisms.

Dogs were likely the first animals to be purposefully genetically modified, with the beginnings of that effort dating back about 32,000 years, according to Rangel. Wild wolves joined our hunter-gatherer ancestors in East Asia, where the aggressive canines were kept in the household and bred to become docile and easier to get along with. Over thousands of years, people bred dogs with different desired character and physical characteristics, eventually leading to the wide variety of dogs we see today.

The earliest known genetically modified plant is wheat. This valuable crop is thought to have originated in the Middle East and northern Africa in the area known as the Fertile Crescent, according to a 2015 article published in the Journal of Traditional and Complementary Medicine. Ancient farmers selectively bred wheat grasses beginning around 9000 B. C. to create improved varieties with larger grains and hardier seeds. By 800 B.C., the cultivation (培养) of improved wheat had spread across Europe and Asia. The continued selective cultivation of wheat resulted in the thousands of varieties that are grown today.

Corn has also experienced some of greatest genetic changes over the past few thousand years. The main crop was changed from a plant known as teosinte, a wild grass with tiny ears and only a few seeds. Over time, farmers selectively bred the teosinte grasses to create corn with large ears bursting with seeds.

Beyond those crops, many of the fruit and vegetables we eat today, including bananas, apples and tomatoes, have experienced several generations of selective raising, according to Rangel.

In 1973, researchers also modified bacteria to be used as drugs. In 1982, human insulin (胰岛素) made from genetically engineered bacteria, became the first genetically engineered human drugs approved by the FDA.

1.What does the word “docile” in paragraph 2 most probably mean?

A.Gentle. B.Loyal. C.Smart. D.Ambitious.

2.How did the ancient farmers try to improve wheat?

A.Through selective cultivation. B.By editing its genes constantly.

C.Through mixture with teosinte. D.By planting it in large numbers.

3.What can we infer about genetic modification?

A.It is rarely seen in daily life. B.It was quite difficult to accept.

C.It is hardly influenced by humans. D.It played a role in medical field.

4.From which section of a newspaper is the text most probably taken?

A.Health. B.Lifestyle. C.Science. D.Agriculture.
