    Scientists are debating how to limit their newly-discovered power to change genetic structure (结构). Scientists already modify the genes (基因) of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes, small flying insects, that carry the Zika virus. They might also be able to permanently remove species (物种) of plants and animals that are damaging to other species.

    In a report published last week, the U. S. National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released (释放) into the wild.

    Sixteen biologists, ethicists (伦理学家) and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms (生物体) from the laboratory into nature.

    Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction (繁殖).

    Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country's borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet.

(1)、What possible advantage does gene control in wild animals and plants have?

A、Changing the Zika virus permanently. B、Getting rid of damaging species forever. C、Having the changed genes in their next generations. D、Making all the species more productive and stronger.
(2)、As for genetically changed wild animals and plants, what are scientists worried about?

A、They may become weaker or die out. B、They may be more productive than before. C、They may cause damage to their living habitat. D、Their genes may spread to later generations.
(3)、Which of the following is true according to the passage?

A、Scientists are certain what exact results gene modification leads to. B、Gene modification can benefit some farm animals and agricultural plants. C、Scientists won't modify any genes before they make the final decision. D、Gene modification will be encouraged in more creatures in the near future.
(4)、The article is mainly intended to ________.

A、appeal against research on gene control B、show how to change genetic structure C、inform us of power and danger of gene control D、give the reason why gene modification is necessary

    To help the environment, many Americans have made the change from paper and plastic bags to reusable shopping bags.But a report by a Florida newspaper says that reusable shopping bags sold by some supermarkets have high levels of lead(铅), which can be dangerous to humans, especially young children.Now, there's a call for a rethink about the use of reusable shopping bags.

     “When our families go to the store looking for safe and healthy foods, the last thing they should be worrying about is a bag,”Charles Schumer, a government official said.“Quick and complete research will allow everyone to make right decisions.”

    The newspaper bought more than a dozen bags sold at Publix supermarkets from Florida supermarkets to test them for lead.The results showed that certain bags had lead levels that worried health officials.Some bags had enough lead in them to be considered dangerous waste if people were to throw the bags out with other rubbish.Lead in the bags is not likely to move onto food.But over time, paint (油漆) on the bags can break off and the bags can wear out.When this happens, lead can be freed.

    The affected (受影响的) bags were found in Florida.But Publix has more than 1,000 stores across America.Publix says that its bags don't break any laws about lead levels, but that they have asked the makers of the bags to reduce(降低) the lead levels in them.

    The bags with the highest levels of lead had beautiful designs and many pictures.Plain reusable bags without them are found to have little lead.People worried about lead levels in reusable bags can turn to cloth.Paper bags are also a good choice, since paper can be reused.

    E-reading and e-books are slowly conquering the world. Compared to traditional paper books, e-books in some schools and universities attract more interest because the information flow seems much easier to manage and comes in a greatly higher quantity.

    Japan is known for the reform-minded attitude towards the gadget(精巧装置)world and for the fact that it is one of the first countries that encouraged in the educational system the emailing of homework.

    The digital textbook looks like the logical step in the world of learning. It is natural but it is also completely untraditional.

    The plan of the largest publishing companies to get in line with the trend is to save a large quantity of paper and make the kids become interested in learning using a cool gadget. Many USA universities and colleges have made students be used to the procedure of downloading the courses and of course the procedure involves interactive software and also the chance of using the computer.

    The traditional education system is still unwilling when it comes to giving up books. The standard approach of information taught out of a book and Shakespeare read out of an old school novel makes studying English as traditional as it can be.

    In a world where kids would rather see the movie than read a book, the digital age has brought along a completely different flavor to reading. Bringing that flavor in school will make teaching a greener and also a completely different matter.

    There are some differences between American English and British English. Some differences are quite interesting.

    When my friend Lily from London used the word “larder”, I didn't know what it meant. Realizing I didn't follow her, she used another word. I finally knew she wanted to find something to keep some food. The next word came up when we were planning a lunch date. She jotted down the date and time in her diary, while I marked my calendar. If she called me on the phone, she would ring me up. But if the line was busy, she would say the line was engaged.

    Most times, I can know what Lily means. Last week, she regretted sending her boys to watch an early morning tennis game without their fleeces. I thought that she meant without their jackets or something like those. Other times, we have to ask each other. She recently told me a funny tale about a woman who was pissed. I wondered what had made the lady angry. It turns out that pissed means drunk.

    Here is one more example. My British friend Jane was filling out a ticket at the grocery store recently. She asked the young man if he had a rubber. When she noticed he didn't follow her, she quickly asked for an eraser, which, in England, is often called a rubber.

    In order to communicate well with the British, we Americans should learn some words that the British use differently. And I think people who learn English as a second language should also realize that there are differences between American English and British English.

    She will face the challenges of riding a bike to school or not being able to climb the monkey bars during playtime. But little Ella Peggie, who was born without her left arm, will get an extraordinary opportunity to share a life-changing bond with her new beloved pet, three-legged puppy.

    When her mother, Brooke Hodgson, saw the one-year-old puppy named Snowy, she knew instantly it would be the perfect companion for her one-year-old daughter. “My heart skipped a beat when I saw Snowy online, ”Ms. Hodgson said. It took just three days for the puppy, who recently had surgery to remove a 1eg, to find a new home after she was sent to the animal shelter last week.

    “I knew she was going to be perfect for Ella—they share the same age so they both have a long life of friendship ahead of them. I just know that Snowy is going to increase her confidence when she is growing up. It's going to be great for Ella when she realizes she's different or when she's having a bad day, she will see the resemblance and know that she's not alone. ”

    Ms. Hodgson has been touched by the relationship between the pair since the lively puppy became the latest addition to the family. And she believes the caring puppy will be by Ella's side through the highs and lows of her life. Ms. Hodgson said, “Every morning Snowy looks for Ella first before she runs to anyone else. It's quite a unique link. I'm just thankful that I was able to give her this dog. I just can't wait for them to get even closer. Not many people are able to do this for their children so we're very lucky to have Snowy. I can't even explain how I feel fight now. ”The young mother said Snowy, who was welcomed into the family just a week ago, has been playing a very special part to Ella's life as well as her three-year-old brother Blake and her father, Stewart Peggie.
