If you have a bad habit of losing things, a new device that can be connected to any item that you might lose may be the way to solve your problem. The Tile, a small square linked up to your iPhone or iPad via Bluetooth, lets you see how close you are to the missing item, within a 50-to 150-foot range . If the item goes out of your phone’s 150-foot range, it can still be detected (發(fā)現(xiàn)) on other smartphones with the same app.

When you log into the app on your phone, it shows you, with green bars that increase or decrease, how far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost item — a dog, for example, or a stolen bike — goes out of your own phone’s 150-foot Bluetooth range, you can set it as a “l(fā)ost item”. If any of the phones with the Tile app comes within the range of your lost item, a message will be sent to your own phone, reminding you of its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it.

Since the Tiles use Bluetooth rather than GPS, they never run out of battery or need to be charged, and they last for one year before needing to be replaced. The app, which will come into the market this winter, works with iPhone 5S, iPhone 6, iPad Mini, iPad 3rd and 4th generation, and iPod 5th generation.

A. find your missing items

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

Winter begins in the north on December 22nd.People and animals have been doing what they always do to prepare for the colder months, squirrels, for example, have been busy gathering nuts from trees. 1.

They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut(黑胡桃）trees. 2. The black walnut tree is also a central part of some hardwood forests.

Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student nowat the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels.Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. 3. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground.

4. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century. The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade（涌入）Indiana. 5.

A. Gray squirrels are native to Indiana.

B. But they seldom remember where they buried every nut.

C. Red squirrels bury nuts in a different way.

D. The black walnut is the nut of choice for both kinds of squirrels.

E. Jake Goheen calls them a sign of an environmental problem more than a cause.

F. Scientists are worried that they will drive away the gray squirrels.

G. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.

科目：高中英語(yǔ) 來源：2016屆江蘇揚(yáng)州中學(xué)高三上10月月考英語(yǔ)試卷（解析版） 題型：閱讀理解

Wikipedia is a free-access, free content Internet encyclopedia(百科全書), supported and hosted by the non-profit Wikipedia Foundation. Wikipedia is ranked among the ten most popular websites and is considered the Internet’s largest and most popular general reference book. Now, Wikipedia is becoming Wookiepedia as scientists hope the informative website will help us reach out to intelligent life forms. So aliens can learn about the human race.

Astronomers would like to beam (播送) the entire contents of Wikipedia into space in the hope of contacting aliens. They want to send messages to hundreds of star systems and planets 20 light years away using radio telescopes. The Search for Extraterrestrial Intelligence Institute, in California, wants to use powerful radio telescopes to try to reach Chewbacca and his mates in a galaxy（銀河系）far away.

The plans will be discussed by astronomers at the weekend as some scientists fear the reply from ET might not turn out to be friendly. Institute scientist David Black said, “One question is if there are dangerous creatures we might be drawing their attention to ourselves. Another is if we go ahead, what message should be sent? There could be many civilizations out there，but if they are all listening and no one is broadcasting or responding, then nothing will happen.”

Professor Stephen Hawking, who has warned that intelligent aliens probably exist and we should keep a safe distance from them, is among those. “If aliens visit us, the outcome would be much as when Columbus landed in America which didn’t turn out well for the Native Americans,” he said.

Signals from Earth’s radio and TV broadcasts have been heading out in space for some 60 years reaching around 5,000 stars.

1.What does the underlined word those in the fourth paragraph refer to?

A. aliens from space

B. astronomers sending signals

C. scientists for the plans

D. scientists against the plans

2.What has Prof. Stephen Hawking warned?

A. intelligent aliens would probably land in America.

B. the plans will be in vain and nothing will happen.

C. none of the civilizations would reply.

D. aliens would bring disasters to the human race.

3.Which can be the best title?

A. Wikipedia, the most popular website

B. Wikipedia to be beamed into space

C. Wikipedia, aliens’ best friend

D. Wikipedia to result in a disaster
