【题目】Green invaders are taking over America. Not invaders from space, but plants! You might not think of plants as dangerous, but in this case they are threatening nature’s delicate food chain.

The invaders are plants brought here from other countries to make gardens and yards look pretty. Ever since people started to arrive on America’s shores, they have carried along trees, flowers, and vegetables from other places. Now there are so many of those plants, they are crowding out the native plants that have lived here since before human settlers arrived.

And that’s a problem, says Dr. Doug Tallamy. He’s insect expert at the University of Delaware. He explains that almost all the plant-eating insects in the United States are specialized, which means they eat only certain plants. Monarch butterfly caterpillars(幼虫),for example, dine on milkweed. If people cut down milkweed and replace it with another plant, the butterflies will not have the food source that they need to survive.

But the trouble doesn’t stop there. When insects can’t get the right plants to eat and they die off, then the birds don’t have enough bugs for their meals. Tallamy points out that almost all migrating birds depend on insets to feed their young.

“We cannot let the plants and animals around us disappear.” says Tallamy, “The way to preserve them is to give them food to eat. But when we plant non-native plants, we are clobbering the food chain, because then we don’t have the insects the birds need to live.”

Fewer of the right plants mean fewer bugs, and fewer bugs mean fewer birds. And that’s bad for the Earth, because we need a variety of living things to keep the planet healthy and beautiful.

The good news is, garden centers sell native plants. “Just Google ‘native plants’ and your location, and you can find out which plants really belong where you live,” says Tallamy

2According to Dr.Tallamy, which of the followings about the insects in the US is NOT true?

A.Almost all the plant-eating insects in a place eat certain plants.

B.Monarch butterfly caterpillars can’t survive without milkweed.

C.If insects can’t eat the right plants, they will find another one.

D.The insects’ death will greatly affect the migrating birds’ survival

3The underlined word “clobber” in Paragraph 5 is closest in meaning to _________.

5What is the best title of the pass age?

A.Green invaders——local living things

【题目】Consumer electronics once again topped the list of the most wanted gifts this holiday season. “Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money buying at least one technology product; definitely a solid vote of confidence for technology.” Steve Koenig is with the Consumer Electronics Association. He says the group’s latest research also shows that Americans this year are spending more on technology products.

“Here in 2012, $252 on average–the technology spend for consumers this year.” From tablet computers to smart phones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. “It’s kind of hard to make a decision.”

Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of CNET.com. The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple’s biggest competitors is the Google Nexus 7. It starts at $199.

“The hardware inside is more powerful than what’s in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple’s maps.” Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. “If you just want to read books and surf the Internet, you don’t really need to get an iPad Mini, but if you want the largest group of apps that’s where the iPad and Apple’s ecosystem shines the most.”

Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through Wi-Fi. This makes it easy for users to email or upload photographs directly from the camera. “You can literally take a picture, upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things.”

Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems. The newest ones work with any device that has Bluetooth technology, including smart phones, laptops and tablets.

With the growing popularity of Internet shopping, many consumers will visit a store first to look at a product, and then go online to find it at a lower price. Stores like Best Buy understand that and they want to stay competitive.

“We have something called the perfect match promise which means if you buy a certain device and you find it cheaper within 30 days we’ll go ahead and price match that for you.” Elman Chacon said.

【题目】UCLA scientists report for the first time on the only known frog species that can communicate using purely ultrasonic(超声)calls, whose frequencies are too high to be heard by humans. Known as Huia cavitympanum, the frog lives only on the Southeast Asian island of Bomeo(婆罗洲).

Ultrasounds are high-pitched sounds more than 20 kilohertz(kHz) in frequency, which exceeds the upper limit of sounds detectable by humans and is far higher than the 5 to 8 kHz frequencies most amphibians (两栖动物),reptiles and birds are capable of hearing or producing. Key parts of the ear must be specially adapted to detect ultrasounds.

The frogs can hear sounds up to 38 kilohertz, the highest frequency that any amphibian species has been known to hear, the scientists report. Humans can hear up to about 20 kHz and typically talk at 2 or 3 kHz.

While most of the more than 5,000 frog species worldwide have eardrums that are flat on the side of the head, Huia cavitympanum has eardrums recessed in the side of the skull, similar to mammals.

Peter Narins, UCLA distinguished professor of physiological science and of ecology and evolutionary biology, and Victoria Arch, a UCLA graduate student in ecology and evolutionary biology, spent several nights in the remote area where the frogs live.

" We had very little information suggesting that they would be in this location," said Arch, lead author of the study. " We found them our first night out. "

The study was published on April 29 in the online journal PLOS ONE, a publication of the Public Library of Science, and is available at
http://dx. plos. org/10. 1371/journal, pone. 05413.

【1】 Huia cavitympanum mainly live __________.

A. in all over the world

B. in many parts of China

D. only on the certain countries' marsh

【2】 This kind of new-found frog can hear each other with up to __________ kHz ultrasounds.

A. 2-3 B. 5 -8

C. more than 20 D. 38

【3】 If people can hear ultrasounds as frogs do, they should __________.

A. hear as frogs do carefully

B. have a pair of good enough ears like frogs

C. concentrate their energy on them

D. turn them into common sounds

【4】 According to the passage we can infer that __________.

A. the result of study is concluded not easily

B. some scientists have done a lot of work for the result

C. all the frogs have the ability with 38 kHz frequency

D. this kind of frogs is as important as animals

【5】 This passage probably appears __________.

A. on the newspaper B. on the textbook
