Be careful what you say around your dog. It might understand more than you think.

A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).

In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.

In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.

The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked

out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.          

Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.

It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!

Do you want to see the effects of global warming? Then head north. Recent studies indicate that the North Pole could be underwater during the summer in less than 10 years, instead of coated in thick sea ice. But seeing the Arctic terrain （地带） up close isn’t easy, unless you’re handy with a dogsled. Steger is going to take all of us there．

Steger, 64, is a great polar explorer. He was the first person to make a dogsled trip to the North Pole, and is also a devoted environmentalist who was early to ring the alarm bell on global warming.

Steger is about to lead a team of six young adventurers on a 1, 400-mile, 60-day-long dogsled trip across Ellesmere Island, in the Canadian Arctic. The sea ice in that region should still be frozen. “We want to take our audience to the front lines of global warming, ” says Steger. The team will be uploading videos, stories and photos to the website global warming 101.com as they march along, allowing armchair adventurers and kids in classrooms to follow their progress day to day.

Steger’s team will include some already-famous young explorers. Sam Branson, 22-year old, is an experienced Arctic traveler. Also on the journey will be 27-year-old Norwegian Sigrid Ekran. Last year Ekran become only the second woman in history to win Rookie （新秀） of the Year for the Iditarod Sled Dog Race.

What they will see may be surprising. Even Steger doesn’t know exactly what to expect. Climate change has already reshaped the geography of the Arctic. “Within a decade or less, it’s going to be impossible to reach the North Pole by dog team, without flotation （漂浮）, ”says Steger.

60．We can learn from Paragraph 1 that                ．

A. climate change happens only in the far north

B. the effects of climate change are obvious in the Arctic terrain

C. climate change is going to be the biggest issue facing human race

D. climate change is the result of pollution

61．It can be inferred that the aim of the dogsled trip is to                   ．

A. encourage young people to explore the Arctic        

B. present the Arctic terrain to geography classes

C. study the cause of climate change in polar region

D. raise awareness of the damage that climate change is causing in polar regions

62．Which of the following statements about Steger’s team is TRUE?

A. Sam Branson, a member, is skilled at travelling in the Arctic.

B. Steger, the leader is a great environmental expert.

C. Ekran, a member, is the second woman to have reached the North Pole.

D. All the members are experienced Arctic explorers.

63．Why does Steger NOT know what they will see during their trip?

A. Because it will be the first time for him to go that far north.

B. Because the sea ice in that region should still be frozen.

C. Because the geography there has changed due to warmer temperatures.

D. Because they will go there by boat instead of by sledge.

In America, when the eighth graders leave the middle school, they are often worried about moving to the high school. It is a hard time for them，but it can be an exciting one as well. To make it easier, students need to get familiar with their school.

    Even though they’ve done this already in the middle school, it’s still important to find where their classrooms are. Most schools take students to the high school for a visit at the end of their eighth grade year. And, most schools also have a freshman (新生) speech for parents and students before the first year begins. Sometimes the main office will give away a map of the school. This can help students and parents to find different places in the school.

    One way to know your high school more and make new friends is to join a club or play a sport．Schools often offer chances to join different clubs and sports. Fall activities begin in August before the first day of school. If you are not interested in sports, there are clubs for any interest, such as drama, dance, chess, photography, community service, etc. These clubs allow students from different grades. By joining an activity, students can find new friendships, not to mention improving their chances in future college applications(申请). The school office will have a list of activities offered at the school and information on how to join them.

    What’s more, to have a great start to a high school year, students can write down some of their worries, and ask for help from teachers and school workers.
