Scientists say they now have proof to support the old-fashioned advice that it's best to sleep on a problem. They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day.
Lead researcher Bob Stickgold at the Harvard Medical School said, "Sleep helps us draw rules from our experiences. It's like knowing the difference between dogs and cats even if it's hard to explain."
The US research team studied how well students remembered connections between words and symbols (象征) , reports New Scientist. They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept. They found that people were better able to remember lists of related words after a night's sleep than after the same time spent awake during the day. They also found it easier to remember themes (主题) that the words had in common. But they forgot around one in four more themes if they had been awake. Prof. John Groeger, of Surrey University's Sleep Research Centre, said, "People have been trying for years to find out what the purpose of sleep is, as we know that only certain parts of it have a restorative (有助恢复的) value. " "We form and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with it all."The phrase" to sleep on a problem" in Paragraph 1 most likely means to______.
| A．pay full attention to a problem | B．wait until later for a decision |
| C．sleep to forget a problem | D．have difficulty sleeping |
In the study by the US research team, students were asked to______.
| A．put together words of similar meanings |
| B．remember words and their meanings |
| C．show their knowledge of words |
| D．make up lists of related words |
Which of the following may be easier to remember?
| A．Themes learned right before the test |
| B．Rules from personal experience |
| C．Words learnt before a good sleep |
| D．Ideas stored together in the brain |
What may be the importance of the research?
| A．It shows sleep may help us manage information |
| B．It helps find out the common themes of word |
| C．It tells us that more sleep can improve health |
| D．It proves the value of old-fashioned advice |
If you're wondering what the top things people do on their Hawaii vacations (besides enjoying the magnificent Hawaii beaches)，look on further.
Whether you're here to see an incredible Hawaii volcano or you want to laze on a beach at a top resort in Kona , Hawaii, knowing ahead of time what you want to do will help you make the most of your trip to Hawaii.
Volcanoes National Park
Most visitors to Hawaii want to see lava from an active Hawaii volcano, and the big island does not disappoint when it comes to this. Spreading out over333,000 acres, the Hawaii Volcanoes National Park takes up a large portion on the southern part of the Big Island. Mauna Loa, rising at 13,677 feet, is easily the largest dormant volcano in the world. Kilauea volcano is where you can see the lava flows (溶岩流）and terrible volcanic landscapes. You can spend days hiking and camping in the Hawaii volcano park, since over half of it is set aside as wilderness. Kona Coast
The Kona coast, on the west side of the Big Island，is home to the top resorts on the big island and the popular Kona vacation rentals. The Kona ar-ea enjoys great weather all year round, in addition to other activities like deep-sea fishing and snorkeling ,making this a popular place for Hawaii beaches. You can also take a tour of the coffee farms that produce the world famous Kona coffee, which is organic and all natural. Kona vacation rentals are popular because many of these look out over the Pacific Ocean, and are close to excellent beaches. Whether your Hawaii vacation includes Hawaii beaches, staying at a resort or booking one of the Kona vacation rentals, this area is one of the best of all islands to stay. Iao Valley
Iao Valley's beauty has inspired Hawaiians to gather here to honor the agriculture god, Lono , during an annual festival called the Makahiki festival. For over a hundred years visitors have been coming to the valley to enjoy the scenic beauty of this lush (青葱的）valley. There are trails in the park, so you can see the best scenery of the cloud-covered valley.

Without proper planning, tourism can cause problems. For example too many tourists can crowd public places that are also enjoyed by the inhabitants of the country. If tourists create too much traffic ,the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country's economy. It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the wealth and happiness of local inhabit-ants.
Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer.
On the other hand, if there is not enough tourism ,people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports, first-class roads, and other support facilities (配套设施）needed by tourist attractions. For example，a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel will lose money.
Building a hotel is just a beginning. There must be many other support facilities as well，including roads to get to the hotel, electricity, sewers (下水道）to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost. Which of the following do you think has been discussed in the part before this selection?
| A．It is extremely important to develop tourism. |
| B．Building roads and hotels is important. |
| C．Support facilities are highly necessary. |
| D．Planning is of great importance to tourism. |
The underlined word “inhabitants” (in Paragraph1) probably means “__________”
| A．citizens |
| B．passengers |
| C．population |
| D．tourists |
Too much tourism can cause all these problems EXCEPT __________
| A．a bad effect on other industries |
| B．a change of tourists' customs |
| C．over - crowdedness of places of interest |
| D．pressure on traffic |
It can be inferred from the text that __________.
| A．the author doesn't like tourism developing so fast |
| B．local people will benefit from tourist attractions |
| C．other parts of a country's economy won't benefit from tourism much |
| D．we can't build too many support facilities |
