A new study shows that rising levels of planet-warming gases may reduce important nutrients（营养物质）in food crops
Researchers studied the effects of carbon dioxide on rice， In the experiment， scientists grew 18 kinds of rice in fields in China and Japan．They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century．Rice grown under high carbon dioxide conditions had，on average，13 t0 30 percent lower levels of four B vitamins and 10 percent less protein（蛋白质）The crops also had 8 percent less iron and 5 percent less zinc than rice grown under normal conditions However， vitamin E leveLs increased by about 13 percent on average．
The researchers said the effects of planet-warming gases would be most sevcre for the poorest citizens in some of the least developed countries．These people generally eat the most rice and have the least complex diets．That includes abour 600 million people in Indonesia， Cambodia，Myanmar，Bangladesh，Laos and other nations，mainly in Southeast Asia．
Other studies have shown that higher temperatures from climate change and weather extremes will reduce food production．But scientists are finding that rising levcls of carbon dioxide and other planet-warming gases threaten food quality．
Earlier studies showed that wheat，rice，field peas and soybeans grown under high carbon dioxide conditions all had Iower levels of protein and mincrais．Scientists predicted that almost 150 million people might be at risk of having too little protein or zinc in their diet by 2050．
The new study suggests a way to lower the nutritional harm of climate change．That is to grow different forms of rice that can adapt to higher carbon dioxide levels．
1.Growing rice under high carbon dioxide conditions may____．
A. increase iron in the rice
B. make it less nutritious
C. cause losses of Vitamin E
D. make it more delicious
2.How can people reduce the nutritional harm of climate change？
A. By importing rice from China and Japan．
B. By taking other kinds of food instead of rice．
C. By avoiding eating rice from Southeast Asia．
D. By growing rice suitable for the environment．
3.What’s the author’s purpose of writing the text？
A. To infom readers what nurrients food crops contain．
B. To call on people to care for the planet they live on．
C. To share the results of some studies on people’s diets．

A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love (早恋) may bring stress for young people and can lead to depression . The study shows that girls become more depressed than boys, and younger girls are the worst of all.
The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study, even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won’t tell that to their parents.
Dr Marian Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendships and a strong sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.
Parents should watch for signs of depression -- eating or mood changes -- and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity (成熟) gives us a chance to avoid its bad side effects.
1.Which of the following is more likely to have depression?
A. Young people who have a strong sense of selfishness.
B. Young girls who always hide their feelings and opinions.
C. Young boys whose parents watch for their behavior.
D. Careless parents whose children are deep in love.
2.What can be inferred from the passage?
A. The older a woman is, the less likely she seems to lose herself in romance.
B. Lacking love can lead young people to grow up more quickly.
C. Early love makes young people keep close to their friends and parents.
D. Parents should help their children to be aware of the signs of depression.
3.What’s the author’s attitude towards puppy love?
A. Confused. B. Disinterested.
C. Scared. D. Disapproving.
4.What’s the main idea of the passage?
A. Puppy love may bring young people depression.
B. Parents should forbid their children’s love.
C. Romance is a two edged sword for adults.
D. Romance is good for young people

A new pollen (花粉) study showed that drought was responsible for the extinction of civilizations more than 3,000 years ago during the Bronze Age.
The reason behind why the civilizations in and around modern-day Israel suddenly broke down more than 3,000 years ago has remained a mystery up until now. A new pollen study by Tel Aviv University researchers finally solved this Bronze Age mystery.
Prof. Israel Finkelstein showed that owing to serious climate changes, the entire world of the Bronze Age crumbled in a short period of time. The discovery was made on the basis of a high-resolution analysis of pollen grains taken from sediments (沉淀物) beneath the Sea of Galilee and the western shore of the Dead Sea.
Prof. Finkelstein received support from the European Research Council to conduct research aimed at reconstructing ancient Israel. Researchers of the part of the project that dealt with climate change extracted (提取) about 60 feet of samples of gray muddy sediment from the center of the Sea of Galilee in northern Israel. They had to drill through 1,000 feet of water and into 65 feet of the lake bed and were able to recover evidence dating over the past 9,000 years.
“Pollen is the most enduring organic material in nature,” explained Dr. Dafna Langgut, a pollen researcher who carried out the actual work of sampling. “These grains tell us about the plants that grew near the lake in the past and therefore prove the climatic conditions in the region.”
Researchers noted a sharp decrease in Mediterranean trees like oaks and pines in the Late Bronze Age. According to study experts, this could be because of repeated periods of drought. The droughts may have resulted in long famines, forcing people to migrate from north to south.
1.The underlined word “crumbled” in Paragraph 3 means _____.
A. settled B. changed
C. established D. disappeared
2.Prof. Finkelstein conducted the new pollen study to _____.
A. earn some money
B. recreate ancient Israel
C. learn more about local plants
D. discover the ancient civilizations
3.By conducting the study, scientists found _____.
A. Mediterranean trees were rare in the Early Bronze Age
B. climate change was to blame for the lost civilization
C. people in the Late Bronze Age starved to death
D. droughts were rare during the Bronze Age
4.The text is most probably taken from _____.
A. a travel magazine B. a history textbook
C. a newspaper report D. an agricultural book
