Each year, millions of people go abroad to work, study or travel. It's a great way to find out what life is like in another part of the world! You're probably hoping to make new friends and learn about the culture in your host country¡ªeverything from attitudes and beliefs to social customs and popular foods. But constantly having to deal with new situations can be frustrating, even stressful.

Homesickness, stress, fear and confusion are all symptoms of "culture shock". At first, you may feel like getting on the plane and heading home. It's OK to have those feelings, and the following are some tips to help you handle the challenges that you will face.

Don't expect to be perfect. You may feel frustrated that you have culture shock, especially since you probably spent so much time preparing for your trip. No matter how much information you read, or how well you speak the host language, it is natural to feel overwhelmed sometimes. If you give yourself some time, things will gradually get easier.

Have an open mind. While it's certainly OK to feel frustration or confusion in your new surroundings, try not to form an opinion about the new culture too soon. Don't think of the host culture as better or worse, just different¡ªyou'll be more willing to try new things.

Participate. This is obvious, but everybody needs to be reminded. Just watching life go on around you isn't good enough. You really need to try things for yourself. Don't worry about making a mistake; people in your host country will generally be very understanding and willing to help if you have questions.

Your study abroad experience is a unique and special time in your life¡ªone that you'll never forget. If you follow our suggestions, you'll be able to handle it well, and have a wonderful time. Good luck!

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 (ËÉÊó), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.

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 (ºÚºúÌÒ) trees. The black walnut is the nut of choice for both kinds of squirrels. 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 now at 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. But they seldom remember where they buried every nut. 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. Professor Swihart calls ¡°death traps for seeds¡±.

Gray squirrels are native to Indiana. 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 Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.

1.The study done by Rob Swihart and Jake Goheen is to ________.

A. find out the living conditions for squirrels

B. learn squirrels¡¯ influence on black walnut trees

C. do something to get rid of squirrels

D. save the forests in the American state of Indiana

2.The difference between gray squirrels and red squirrels mainly lies in ________.

A. the way they gather the walnut

B. the time they have winter sleep

C. the place they have winter sleep

D. the place they store the walnuts

3.When Professor Swihart says ¡°death traps for seeds¡±, he actually means that ________.

A. red squirrels eat more nuts than gray squirrels

B. gray squirrels and red squirrels will have severe fights

C. nuts above the ground will not develop into plants

D. seeds can be traps for other animals in the forest

4.According to the passage, which of the following is true?

A. The black walnut is equally attractive to both gray and red squirrels.

B. Gray squirrels do more harm to the forest than red squirrels.

C. Red squirrels and gray squirrels have helped the spread of walnut trees.

D. The cleaning of forest land benefits red squirrels directly.

Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It¡¯s awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.

It may sound risky, so many teens stay within their own social circles to find rides, and don¡¯t branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.

¡°I think the digital connection of young people is really important, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they¡¯ve been very used to sharing,¡± said Juliet Schor, a sociology professor at Boston College.

The sharing economy got big during the recession (¾­¼ÃË¥ÍË), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, ¡°The symbol of freedom isn¡¯t the car any more because there¡¯s technology out there connecting you to a car.¡±

According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver¡¯s license compared to six in ten today. So it¡¯s not that surprising that on my 16th birthday I wasn¡¯t rushing to get a license but an iPhone.

¡°Driving, for young people, does mean they have to disconnect from their technology, and that¡¯s a negative. So if they could sit in the passage side and still be connected, that¡¯s going to be a plus.¡± Schor continued.

To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.

1.The American teens prefer to possess an iPhone as a birthday gift because ______.

A. it is most fashionable and cool B. they are bored with driving cars

C. they are fond of being connected D. it is much cheaper than a car

2.We can learn from the text that ______.

A. Twitter is a website for teens to make friends and achieve goals

B. ridesharing can be seen as a sign that people still count on each other

C. drwing cars for teens means a plus and connecting with technology

D. having a car and cost-sharing symbolize more freedom for the author¡¯s mother

3.Professor Juliet would agree that ______.

A. young people will sit waiting to be contacted by reading a passage

B. sharing economy is bound to be responsible for the recession

C. young people tend to share a car with strangers by means of Twitter

D. being connected via technology comes first for young people

4.The best title for the passage is probably ______.

A. Twitter, an Awesome Website B. Cars or iPhone

C. Teens Use Twitter to Thumb Rides D. Cool Teens on the Go

How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the U. S.

For some parents, the Internet can seem like a jungle, filled with danger for their children. 1. With good guides, some education,and a few precautions(Ô¤·À´ëÊ©), the wilds of the Internet can be safely navigated(º½ÐÐ). ¡°Kids have to be on-line. If we tell our kids they can¡¯t have access (»ú»á) to the Internet, we¡¯re cutting them off from their future,¡± said an expert.

Most kids have started to use search engines. 2. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. 3. But this can¡¯t be wholly reliable(¿É¿¿), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet.

4.

A few other tips

¡ñ Don¡¯t put the PC in a child¡¯s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.

¡ñ Ask your child what he or she has been doing and about any friends they make on-line.

¡ñ 5.

¡ñ And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

A. The most popular way to limit access would be to use what is known as a ¡°content screener(¹ýÂËÆ÷)¡±.

B. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go.

C. Tell your child not to give on-line strangers personal information, especially like address and phone number.

D. But jungles contain wonders as well as dangers.

E. Tell your child not to talk to any strangers.

F. Another way is that mum or dad is nearby when the child is surfing(ä¯ÀÀ) the Internet.

G. And also parents can help the child in trouble.

Imagine looking at something and being able to move it just by using your brain!That is exactly what the new technology called BrainGate can do ¡ªwith the help of a robotic arm,anyway.

BrainGate is the idea of Professor John Donoghue and his team of researchers at the Brown Institute for Brain Science,USA. BrainGate is attached directly to the brain. First of all,gold wires are put into the part of the brain that controls movement. These are then connected to a small computer chip(оƬ) . When the person thinks about different movements,this creates electrical signals,which are picked up by the chip. After this,the signals that are created by the brain are sent back to a computer,which changes the signals into movements. Finally,the computer uses the robotic arm to carry out these movements. BrainGate can already be used to write an e-mail or play computer games,just by brain power.

The technology has already cost millions of dollars to develop and when it is available for use,it will probably cost thousands of dollars per person. There are still many challenges ahead for Donoghue and his team. They are currently planning a mini wireless version,which will allow people to be connected to the computer at all times. Donoghue also dreams of using this technology to help disabled people who can't move their arms or legs. He plans to connect BrainGate directly to their own paralysed limbs(̱»¾µÄ¸ì²²»òÍÈ) .This will mean that the person can control their own body again,without relying on a robotic arm.

This research is attracting the military's (¾ü·½µÄ) attention as well. However,it is easy to understand why scientists might be concerned about how thought-controlled machines could be used by the military.

1.What does the underlined word ¡°These¡± refer to?

A. Movements. B. Thoughts.

C. Brains D. Wires.

2.What is one of BrainGate's disadvantages?

A. It needs improvement. B. It produces few movements.

C. It is too expensive. D. It is difficult to control.

3.How will Donoghue help disabled people?

A. By developing a wireless version.

B. By replacing their limbs with robotic ones.

C. By making BrainGate smaller.

D. By attaching BrainGate to their bad limbs.

4.What does the military think of thought-controlled machines?

A. They could lead to disasters. B. They would face fierce competition.

C. They could be useful. D. They would be in mass production.
