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 (发现) 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 “lost 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.

1.The Tile app can help you 　　 .

A. find your missing items

B. use your phone more wisely

C. save your phone’s battery power

D. connect something to your phone

2.Which of the following is TRUE according to the passage?

A. The Tile needs to be charged after a year of use.

B. One smartphone can only be linked up to one Tile.

C. The Tile cannot work when linked up to a phone without Bluetooth.

D. A missing item can’t be found if it goes out of the needed range.

3.What does the second paragraph mainly tell us?

A. What the Tile app is.

B. How the Tile app works.

C. The advantages of the Tile app.

D. Why the Tile app was invented.

4.Where does this passage probably come from?

We ended up putting off our trip to Disney so we could visit Aunt Loretta.

I tried to talk Mom into letting us do something normal, like going to a water park for the day, but she didn't want to hear it.　 She said that spending a lot of time together in the car would be a " bonding"　 experience for the whole family.

How would you feel if moving to a new town meant losing track of your friends? What if the only way of getting news from faraway friends was writing letters that took ages to be delivered? 1. Thanks to advances in technology, how we make friends and communicate with them has changed significantly.

Nowadays, we can move around the world and still stay in touch with the people that we want to remain friends with. Social media tools let us see what our friends are up to and maintain friendships. 2.

The digital age also enables us to find people who share our interests, such as collecting model cars or playing an unusual instrument. Whatever our hobbies, the Internet can connect us with others who also enjoy doing them, even if they live on the other side of the world.

But when you “friend” people online, does this mean that they really are your friends?

3.

If people always exchange true personal information online, then yes, these friendships can be real and meaningful. But we need to keep in mind that what we see on social media is often not the whole truth about a person.

On social media sites, people tend to post only positive updates that make them appear happy and friendly. But smiling photos can hide real problems. 4. A young person could be old; a woman could be a man; we could even be sharing our information with criminals.

5. Although technology has changed the way we acquire friends, the meaning of friendship and our longing for friends remain the same. As Aristotle said, no one would choose to live without friends, even if he had all other goods.

A.It depends.

B.All you need is a Wi-Fi connection.

C.It’s a problem that’s getting a lot of coverage.

D.This was how things worked not very long ago.

E.Remember the saying: on the Internet, nobody knows you’re a dog.

F.But that doesn’t mean that a higher percentage of people feel lonely now.

G.But this doesn’t mean that we should throw the baby out with the bathwater.

Did you know that people who live in different parts of China have different habits and preferences？

For example， people from southern China prefer to eat vegetables， while people from north China like to eat meat． But what causes these differences？

According to a new study published in the journal Cell in October， gene variations （基因变异） might be responsible for these differences， Xinhua reported．

In the study， researchers from Chinese genome-sequencing （基因组测序） firm BGI collected genetic information from 141，431 Chinese women． The women came from 31 provinces and consisted of 36 ethnic minority groups．

The researchers found that there are six gene frequencies that are different among people from both northern and southern China． They found that natural selection has played an important role in the ways that people living in different regions of China have evolved， affecting their food preferences， immunities （免疫性） to illness and physical traits （特点）， the New York Times reported．

The researchers reported that a variation of the gene FADS2 is more commonly found in northern people than it is in southern people． It helps people metabolize （新陈代谢） fatty acids （脂肪酸）， which suggests a diet that is rich in meat． According to Xinhua， this is due to climate differences． Northern China is at a higher latitude， which means it's cold and dry throughout the whole year． This weather is difficult to grow vegetables in． Therefore， northerners tend to eat more meat．

The study also found differences in the immune systems of both groups． Most people in southern China carry the gene CR1， which protects against malaria （疟疾）． This is because malaria was once quite common in southern China． In order to survive， the genes of people in the south evolved to fight against this disease． However， people in the south are also more vulnerable to certain blood-borne illnesses， as they lack the genes to stop them．

Genes can also cause physical differences between northerners and southerners． Most northerners have the ABCC11 gene， which causes dry earwax （耳屎）， less body odor and fewer sweat secretions （分泌）， The New York Times reported． These physical differences are also more beneficial to living in cold environments． Southerners are less likely to have this gene， as it did not evolve in their population．

1.What's the new study mainly about？ ______

A. The genes of Chinese minority groups．

B. Habits of people from different regions of China．

C. Differences in the genes of people from different parts of China．

D. Physical differences between northerners and southerners．

2.A variation of the gene FADS2can help our body ______ ．

A. store fat B. digest meat

C. fight disease D. control body temperature

3.The underlined word "vulnerable" in Paragraph 7 is closest in meaning to ______ ．

A. unprotected B. uninterested

C. generous D. responsible

4.Compared with people in south China， most northerners ______ ．

a．are immune to malaria

b．catch blood-borne illnesses easily

c．have less body odor

d．sweat less frequently

A. ab B. bc

C. bd D. cd

Engineers in Upstate New York have invented a folded paper device that looks like a decorated art project. But don't be fooled. This is actually a paper-based battery. No, it doesn't look like any of those metal batteries running flashlights or smartphones. In these systems, the battery can be printed on a page. The battery 's power consists of living bacteria.

Paper electronics are simple to make and inexpensive, notes study leader Seokheun Choi, an engineer at Binghamton University. They need no electrical outlet to recharge. They just need more bacteria, which can be found everywhere — including dirty water.

“ Most batteries use chemicals to generate electricity. Substituting bacteria can be an advantage,” Choi says.“They are cheap and self-repairing.” What paper-based batteries won't do is generate much power. They do, however create enough to run small devices in faraway or dangerous places — such as a battlefield . They might also find use in medicine . For instance, they might power tiny sensors, such as the types used to measure blood sugar.

This invention is based on an observation made more than a century ago — that microbes （微生 物） produce electricity as they digest food. Scientists refer to the bio-batteries based on this principle as microbial fuel cells. A fuel cell generates electricity like a regular battery. But a regular battery stops producing electricity when its inner chemical reactions stop. A fuel cell uses fuel that can be refilled. In this case, bacteria serve as the fuel. By refilling more microbes, as needed, scientists can keep these fuel cells running.

Lab tests have shown that the new battery can produce a current. Now, Choi and his team are looking at ways to increase the power. They're studying different shapes and materials for the anode and cathode （正负 极）. They're also looking for the best ways to combine batteries for more power. The beauty of the paper devices is that you can simply fold them to connect them. And they surely will be a trend in the near future.

1.What makes the paper-based batteries different from other batteries?

A.They are mainly used to run smartphones.

B.They use bacteria to generate electricity.

C.They are used to decorate small devices.

D.They take a much shorter time to recharge.

2.What can the paper-based batteries do?

A.Power tiny devices. B.Lower blood sugar levels.

C.Produce much electricity. D.Change chemicals in the paper.

3.What is the fourth paragraph mainly about?

A.The application of the new battery.

B.The characteristics of the paper batteries.

C.The intention to invent the device.

D.The working principle of the invention.

4.What is the author's attitude towards the development of the paper-based batteries?

A.Defensive. B.Optimistic.

C.Doubtful. D.Ambiguous.
