April will bring a new product - the Apple Watch - into the market. Last week, the watch was firstly introduced by Tun Cook, Apple's CEO. The price of the watch will differ from $349 to $1,099, depending on its size, strap and whether it is a sports or regular style.
Apple engineers and designers have put in a lot of thought and hard work into creating this "small screen" on your wrist(手腕). The "sensor" on the screen not only detects your finger, but knows the difference between when you are tapping, and when you are pressing harder.
The watch also has "hal)tic feedback(触觉反馈)". You can send personal messages to your friend - such as drawing a star or a special sign with your fingers, or tapping the watch, say 3 times, and your friend will receive those taps on their wrist. Besides telling the time, the watch will use bluetooth' to connect with your iPhone and show calls or text messages that come in.
According to Tim Cook, the watch may open up a whole new area of applications that we had never thought of. Some car factories like BMW have developed an app that allows its car owners to open their cars with the watch. A Hotels' app may allow you to open the door to your hotel room without worrying about losing the smart-card. And finally, even airlines are jumping in - passengers may be able to simply wave their wrist to check into their flight.
The biggest use of the watch, however, is as your personal fitness coach. The watch can measure your pulse (heartbeat) using a sensor at the bottom of the watch. It also has the same "accelerometer" as your iPhone, so it knows when you are moving, and also how much you are walking or running, It will remind you if you have been sitting for too long without much activity.

If you get into the forest with your friends, stay with them always. If you don’t, you may get lost. If you really get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you by staying in one place.
There is another way to help your friends or other nearby people to find you. Give them a signal (信号) by shouting or whistling (吹口哨) three times. Any signal given three times is a call for help.

They give you two shouts, two whistles, or two gun-shots (枪声). When someone gives you a signal, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a little house---cover up to the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.
What should you do if you get hungry or need drinking water? You would have to leave your little house to look for a river. Don’t just walk away.

If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.
“Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),” he said. “You are actually going beyond language and have a better understanding of different ideas.”
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.
The main subject talked about in this passage is ________.

A．science on learning a second language

B．man’s ability of learning a second language

C．that language can help brain power

D．language learning and maths study

The underlined word “bilingual” probably means _______.

A．a researcher on language learning

B．a second language learner

C．a person who can speak two languages

D．an active language learner

We may know from the scientific findings that ________.

A．the earlier you start to learn a second language, the higher the grey matter density is.

B．there is no difference between a later second language learner and one who doesn’t know a second language

C．the experience of learning a second language has bad effect on people’s brain

D．the ability of learning a second language is changing all the time

In the last two paragraphs, the author wants to tell us that _________.

A．learning a second language is the same as studying maths

B．early learning of a second language helps you a great deal in studying other subjects

C．Italian is the best choice for you as a second language

D．you’d better choose the ages between 2 and 34 to learn a second language
