One basic kind of mum is the garden mum. The other basic kind is the florist mum. The garden mum is better able to handle different growing conditions.
There are many varieties of mums. The decorative mum is often seen in gardens. Another popular type, the quill mum, has long, straight petals（花瓣）like a tube or needle.
Chrysanthemum blooms can be white, yellow, gold, red or other colors. The plants often grow one meter high.
The soil for chrysanthemums should be kept moist but well drained so it does not get too wet.
Newly-planted mums should be watered two or three times a week, depending on conditions. Plants established in the ground may do well just with normal rainfall.
Mums grow best in full sunshine. They produce colorful blooms when days get shorter and nights get longer. The life cycle of the plant depends on the amount of daylight. This is why experts advise against placing mums near night lights or street lights. The light may interfere with their normal growth cycle. The plants may develop buds too soon.
In climates where temperatures fall below freezing, plant mums at least six weeks before the first frost. That way, the plants will be well established for cold weather.
Some gardeners say the most beautiful presentation comes from planting mums close together. But be sure to leave enough space to let air flow between the plants. If not, there may be a greater chance of disease.
To get more blooms, gardeners pinch（掐）back the branches when new growth has reached fifteen centimeters. Squeeze about five to seven centimeters off each branch. Pinch it again when a branch grows another twelve to fifteen centimeters. Stop the pinching about one hundred days before you want the plants to bloom.
小题1: What has a great effect on the life cycle of the mum?
| A．The conditions of the soil. | B．The amount of daylight. |
| C．The amount of rainfall. | D．Cold weather. |
| A．To make mums grow thick. | B．To get more blooms. |
| C．To prevent mums from falling ill. | D．To let air flow between the plants. |
| A．Growing mums has a very long history and all the people in the world like making tea with mums. |
| B．Mums can grow one meter high and the closer they are planted, the higher they grow. |
| C．Though planting mums close together can make them look more beautiful, enough space should be left. |
| D．The petals of mums are long and straight and the more water mums get, the more quickly they grow. |

The following are taken from these books. You will find much more information about these hotels in the books.
Kakslauttanen Hotel
It is the home of the famous Igloo（冰屋）Village with the unique glass and snow igloos and the world’s largest snow restaurant. In addition , their guests can enjoy the winter activities including watching the Northern Lights visible generally from late August to late April. Guests can sample the peace of sleeping in snow. Their glass igloos are fantastic for lying on your bed at night, watching the Northern Lights in the warm. You can enjoy cold or warm night sleep as required.
Art Hotel in Ronda
Beautifully situated in the oldest paved street of Ronda and surrounded by historic buildings, Art Hotel is decorated with original and historical artwork and atmospheric lighting. There is lots of fun and funky touches, e. g. lights and birds nesting in old basketballs, wall murals（壁画）of Michael Jackson , car tyres converted to occasional tables.
During your stay, all drinks, breakfast and the use of all facilities are included in the price of the room.
Otter Creek Tents
The tents are separated from the rest of the world by a quiet salt-water creek. A coconut plantation dating back to 1886, the secret location preserves the privacy and peace of guests, with the salt water of the creek keeping even the mosquitoes away.
Each tent sleeps 2 in a four-poster double bed and has a western style toilet and bathroom with running water and hot shower. The tents use the dining facilities of the charming “Elsewhere” beach houses and enjoy over a mile of the pristine（处于原始状态的）beach where one can still see the footprints of fishermen , and during the season , possibly the prints of sea turtles.
The Original Icehotel
“Imagine a hotel built from thousands of tons of snow and ice, and rebuilt every winter”--that is ICEHOTEL in northern Lapland, Sweden.
This is the original ICEHOTEL, first created in the early 1990s. It has become the global ambassador for this genre and now licenses ICEBARs around the world too. With 80 ＋ rooms, the property is a huge undertaking to be rebuilt every year, and their expertise inspired other similar properties in North America and elsewhere.

Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用). Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip (硅片) with catalysts (催化剂). Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell (电池), which uses those two materials to produce electricity, located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card, scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Docera at a conference of the American Chemical Society.
An artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf, by contrast, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf prorotype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera’s recent discovery of several powerful new, inexpensive catalysts. These catalysts make the energy transformation (转换) inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available; that is, it doesn’t need pure water. This is important for some countries that don’t have access to pure water.
With the goal to “make each home its own power station” and “giving energy to the poor”, scientists believe that the new application could be widely used in developing countries, especially in India and rural China.
小题1:Which of the following order correctly shows how the artificial leaf is used to produce electricity?
a. artificial leaves split water into hydrogen and oxygen
b. the hydrogen and oxygen gases are stored in a fuel cell
c. the artificial leaves are put in water
d. the fuel cell uses hydrogen and oxygen to produce electricity
| A．cbad | B．cabd | C．bcad | D．cadb |
| A．They are inexpensive but unstable. |
| B．They are as efficient at carrying out photosynthesis as natural leaves. |
| C．They can work only in pure water. |
| D．They need several catalysts to help them work efficiently. |
| A．build-up more power stations in the world |
| B．provide cheaper energy for developing countries |
| C．offer people in developing countries access to pure water |
| D．gain a deeper understanding of the photosynthesis process |
| A．Introduction to the history of artificial leaves. |

The psychologist Jean Piaget (1896-1980) has been credited with making a major breakthrough in this area when he put forward his idea that children were not actually less intelligent than adults, rather they just thought in a different way. Preciously the development of children right from birth through to adulthood was an area that was almost completely neglected. In fact very little work was done in this area. However, interest in this field has now developed to the point of being one of the most debated of all the areas of psychology.
Despite popular belief that factors such as genetics or personal characteristics are the only determining factors that influence a youth’s behavior, this is not in fact the case. In reality, development actually includes many more factors than those contained within an individual. Factors such as environment, which can include social relationships and the surrounding culture, also play important roles. Relationships with both peers and adults will no doubt affect how children think and learn, and therefore develop. These relationships can include those that are found not only within families but also in schools and peer groups.
Culturally speaking, this factor will contribute greatly to how children develop their personality concerning the values they end up holding (perhaps for a lifetime) as well as how they view such things as traditions and customs.
Nowadays, psychologists have agreed that a child’s psychology is both unique and highly complex. However, there are debates on many different points in this field and many viewpoints exist.
小题1:The word “neglected” underlined in Paragraph 2 can be replaced by “______”.
| A．ignored | B．destroyed | C．developed | D．explored |
| A．Popular belief about child psychology. |
| B．The role families play in a child’s development. |
| C．Factors that affect a child’s development. |
| D．The importance of relationships to a child. |
| A．introduce an important psychologist. |
| B．give a brief introduction to child psychology. |
| C．compare some of the areas of psychology. |
| D．explain the development in psychology. |
Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 infants aged nine months to 36 months. The babies were allowed to choose from seven toys. Some were stereotypically boys" toys - a car, a digger, a ball and a blue teddy. The rest were girls’ toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded.
Of the youngest children (nine to 14 months), girls spent significantly longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two-and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents’ view on which toys were more appropriate for boys or girls, and the children’s choice.
Dr Brenda Todd said: “Children of this age are already exposed to much socialization. Boys may be given ‘toys that go’ while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts（本能）, while girls prefer warmer colors such as pink, the color of a newborn baby.”
小题1:Baby boys and girls have different toy preferences probably because .
| A．baby boys are much more active |
| B．baby girls like bright colors more |
| C．their parents treat them differently |
| D．there is a natural difference between them |
| A．Nine-month-old baby boys don’t play with dolls at all. |
| B．Two-year-old baby girls sometimes play with cars and balls. |
| C．The older the babies are, the more obvious their preference is. |
| D．Parents should teach their babies to share each other’s toys. |
| A．Adults purposely influence their babies preference. |
| B．Babies’ preference isn’t affected by social surroundings. |
| C．Baby boys preferring to moving toys will be good at hunting. |
| D．Baby girls preferring warmer colors will be warm-hearted. |
| A．science | B．health | C．education | D．entertainment |
Charter schools are self-governing．Private companies operate some charter schools．They are similar in some ways to traditional public schools．They receive tax money just as other public schools do．Charter schools must prove to local or state governments that their students are learning．These governments provide the schools with the agreement called a charter that permits them to operate．
Charter schools are different because they do not have to obey most laws governing traditional public schools．Local, state, or federal governments cannot tell them what to teach．Each school can choose its own goals and decide the ways it wants to reach them．Class size is usually smaller than in traditional public schools．
The Bush Administration strongly supports charter schools as a way to re-organize public schools that are failing to educate students．But some education agencies and unions oppose charter schools．One teachers" union has just made public the results of the first national study comparing the progress of students in traditional schools and charter schools．
The American Federation of Teachers criticized the government"s delay in releasing the results of the study, which is called the National Assessment of Educational Progress．Union education experts say the study shows that charter school students performed worse on math and reading tests than students in regular public schools．
Some experts say the study is not a fair look at charter schools because students in those schools have more problems than students in traditional schools．Other education experts say the study results should make charter school officials demand improved student progress．
小题1:If a private company wants to operate a charter school, it must______．
| A．try new methods of teaching | B．prove its management ability |
| C．obey the local and state laws | D．get the government"s permission |
| A．Doubtful | B．Supportive. | C．Subjective． | D．Optimistic． |
| A．More students choose to attend charter schools． |
