The evolution of the first animals may have oxygenated（供氧）Earth's oceans. New research

led by the University of Exeter challenges the long held belief that oxygenation of the atmosphere and oceans was a precondition for the evolution of complex life forms.

The study, published in the journal Nature Geoscience, builds on the recent work of scientists in Denmark who found that sponges（海綿動物）一the first animals to evolve一require only small amounts of oxygen.

Professor Tim Lenton of the University of Exeter, who led the new study, said: "We argue that the evolution of the first animals could have played a key role in the widespread oxygenation of the deep oceans. This in turn may have facilitated the evolution of more complex, mobile animals."

Critical to determining oxygen levels in the deep ocean is the balance of oxygen supply and demand. Demand for oxygen is created by the sinking of dead organic material into the deep ocean. The new study argues that the first animals reduced this supply of organic matter一both directly and indirectly.

Sponges feed by pumping water through their bodies, "digesting" the tiny particles of organic matter, and thus helping oxygenate the shelf seas that they live in. By oxygenating more of the bottom waters, the first animals actually increased the removal of the essential nutrient phosphorus（磷）in the ocean. This in turn reduced the productivity of the whole ocean ecosystem, lowering oxygen demand and thus oxygenating the deep ocean.

A more oxygen-rich ocean created ideal conditions for more complex mobile animals to evolve, because they have a higher requirement for oxygen. These included the first predatory（肉食的）animals with guts（內(nèi)臟）that started to eat one another, marking the beginning of the type of food webs we are familiar with today.

Professor Simon Poulton of the University of Leeds, who is a co-author of the study, added: "This study provides a possible mechanism for ocean oxygenation without the requirement for a rise in atmospheric oxygen. It therefore questions whether the long-standing belief that there was a major rise in atmospheric oxygen at this time is correct. We simply don't know the answer to this at present, which is ultimately key to understanding how our planet evolved to its current habitable state. Geochemists need to come up with new ways to explain oxygen levels on the early Earth."

1.The underlined word "facilitated" in Para. 3 is closest in meaning to＿＿．

A. prevented B. promoted C. interrupted D. witnessed

2.From paragraphs 4 to 6, we can infer that＿＿．

A. phosphorus can keep the productivity of the ocean ecosystem

B. complex animals consume the same amount of oxygen as sponges

C. the sinking of dead organic material into the deep ocean produces oxygen

D. the existence of the first animals marks the beginning of modern food webs

3. From the last paragraph, we can learn Pro. Simon Poulton believes that＿＿．

A. their study gives a new explanation for the high oxygen content in the air

B．oxygen increased greatly in the air as the first animals oxygenated the oceans

C. their study answers the question of how the earth evolved to the present state

D. ocean oxygenation does not necessarily require a rise in atmospheric oxygen

4.The main purpose of the passage is to＿＿．

A. present the view that the first animals played an active role in oxygenating oceans

B. introduce two opposite opinions on how the first animals oxygenated oceans

C．a(chǎn)nalyze how atmospheric oxygen stepped up the evolution of oceanic animals

D. explain how oceanic oxygen determines the amount of atmospheric oxygen

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 smartphones, 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 smartphones, 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.

1.According to Brain Tong, ________.

A. the Apple’s iPad Mini is more suitable for enthusiastic readers

B. the hardware in iPad Mini is more advanced than that in Nexus 7

C. Nexus 7 has fewer apps than iPad Mini

D. iPad mini is more eco-friendly

2.If you’ve discovered that a certain device you bought at Best Buy is more expensive than one at another store, ________.

A. you are sure to get double the amount you paid

B. you can return the device and get your money back

C. the store will return the price differences

D. the store will lower the price within 30 days

3.Which of the following would be the best gift for a cab driver?

A. Smart cameras.B. Streaming media boxes.

C. Wireless speaker systems.D. Tablet computers.
