While walk my dog this morning, I happened to see a heartwarming sight. A mother was rushing towards her car with her children’s schoolbags. Behind her was two children crying at the top of their voices. They barely moved their foot. Instead, they were too busy crying or seeking for attention. After the mother had been placed the schoolbags in the car, she ran towards her children with her arms widely open. She smiled as she approached them, held one in her left arm, the another in her right and carry them both to the car. The children's tears changed to laughter in flash.
Seeing this, I was moved by tears because of the mother's strength and love for her children.
In March 2017, about 25 people 1.（invite）to a kitchen in San Francisco, California, for a tasting event. On the menu? Fried chicken grown in a lab by scientists from Memphis Meats.
The company makes meat by 2.（safe）extracting（提取）cells from animals such as chickens, ducks, and cows. Then 3. feeds the cells nutrients（营养物）.Those cells grow, 4.（form）muscles, which are meat. Memphis Meats is one of several companies in the world making lab-grown meat. Why do they produce lab-grown meat?
Producing meat with 5.（tradition）methods requires lots of cows. And cows give off a gas that traps heat in the atmosphere, which contributes 6. climate change. Raising cows takes up space, too. But lab- grown meat production requires fewer cows and less land. The cells taken during one extraction can make 7.（much）meat than "any single animal could ever produce”.
Lab-grown meat is not yet sold in supermarkets. Before that can happen, it will need to be affordable. The 8. （one）lab-grown burger, 9.（produce）in 2013 by Mosa Meat, cost over $300,000 to make. Costs are dipping. But they can't yet compete with regular ground beef, 10. is about $4 a pound.

It's free and requires no equipment. Besides, the scenery can be amazing. It's no wonder running is among the world’ s most popular sports. Research suggests running can significantly improve your health. 1.
Running just once a week, or 50 minutes a week, reduces the risk of death at a given point in time. 2. This is good news for those who don't have much time on their hands for exercise. But it shouldn't discourage those who enjoy running longer and more often. We found even "hardcore" running (for example, every day or four hours a week) is beneficial for health. Nor do the benefits necessarily increase by running at high speeds. We found similar benefits for running at any speed between 8 and 13 km/h. It might be that running at your own "most comfortable pace" is the best for your health.
3. Running may lead to overuse injuries. These occur as a consequence of repeated mechanical stress on the tissue without enough time for recovery. Sudden death is also likely to happen during exercise, though, this occurs very rarely.
Therefore, for beginning runners, start slow and gradually increase the pace, duration and weekly frequency. Set your aim at 50 minutes a week or more, and run at a comfortable speed.
If you don't like running alone, consider doing it along with others. 4. It can be hard to start running, but it shouldn't be too hard. 5. There are more than 800 other interesting sports to choose from. The benefits of many other sports (such as swimming, tennis, cycling and aerobics) are comparable to the ones found for running.
A.If you don't like running, don't force it.
B.However, keep it in mind that there are risks as well.
C.It also indicates you needn't run fast or far to gain the benefit.
D.It can increase your motivation and provide a fun social experience.
E.Running may help you live longer but more isn't necessarily better.
F.The benefit doesn't seem to increase or decrease with higher amounts of running.
G.Doing it in many sessions spread across the week brings much more benefits.
Australian consumers in Adelaide are taking part in a study to help realize the potential for edible（可食用的）insects as a food industry. Consumers' attitudes are being put to the test at Adelaide Central Market with an offering of roasted crickets and ants, mealworm cookies and cricket energy bars.
Researchers want to further probe consumers' attitudes towards edible insects, and evaluate taste preferences and consumers5 willingness to buy such products. In an earlier online survey of 820 Australian consumers, the researchers found that 20% had tried edible insects. Of those surveyed, 46% said they'd be willing to try a cookie made from insect flour.
" In the earlier survey, consumers said they were most likely to try flavored or roasted insects and least likely to want to try cockroaches or spiders," Dr Crump says. "In this taste test, we've chosen products that consumers are most likely to react positively towards―apologies to anyone keen to try a cockroach or spider. The samples we'll be offering consumers provide a good spread of the available insect products in Australia' s marketplaces, some of which may be more acceptable than others."
Dr Crump says the research will help guide the development of an edible insect industry. In Australia, edible insects remain a new agricultural industry. Consumer research is needed to improve consumer acceptance of edible insects, so as to realize their potential as an alternative protein（蛋白质）source.
Professor Kerry Wilkinson says edible insects could play a role in global food security. "Problems such as climate change, increasing global population, shortage of agricultural land and rapidly changing consumer preferences are common, particularly in developing countries where there is an increasing demand for high quality animal protein," he says. "These food security problems will only be overcome by a change in food consumption habits. Edible insects could provide one solution. We want to look at ways of overcoming barriers to insect consumption in Australia.
1.What does the underlined word "probe" in paragraph 2 most probably mean?
A.Explore. B.Influence. C.Describe. D.Compare.
2.Why have the researchers chosen certain insect products for the taste test?
A.Because they are richer in protein than other insects.
B.Because it is not difficult to flavor or roast them.
C.Because they are widely acceptable in Australia.
D.Because they are probably to consumers' taste.
3.In Kerry Wilkinson's opinion, how can consumers help remove food security problems?
A.By taking in less animal protein.
B.By changing their eating habits.
C.By expanding agricultural land.
D.By controlling their appetite.
4.What can be the best title for the text?
A.Insects Make Food Security No Longer a Problem
B.Could Edible Insects Help Global Food Security?
C.Edible Insects Prove an Alternative Protein Source
D.What Counts Most When It Gomes to Edible Insects?
