Eight percent of Sweden’s energy supply, for example, is presently coming from wood bark and pulp remainings, Sweden intends to raise this percentage by more intensive harvesting of waste food lying around in forests, and through the planting of so-called energy forests of fast-growing trees such as willow and birch.
Brazil is frequently pointed to as a nation with a major successful investment (投资)in energy coming from grains: it presently runs 330,000 automobiles on a water and alcohol (酒精) mixture, replacing 10 percent of its previous oil supply. Brazilian representatives (代表) at the conference said they wish to double this in five years, with a final goal of total replacement. Most of the cars are built at the factory to use the mixture, while older models are changed through low-cost government programs.

In their experiment, 5 healthy 6-month-old infants from middle-class families viewed slides showing eight pairs of white male faces and eight pairs of white female faces. Each pair, displayed for 10 seconds, consisted of one attractive and one unattractive face, as previously judged by a group of male and female college students. An experimenter viewed the young participants on a video monitor and recorded the direction and duration of each infant’s gaze.
The 35 boys and 25 girls looked longer at both male and female faces judged as attractive, the researchers found.
Their second study of 6-month-old involved 15 boys and 25 girls, mostly white, who saw eight pairs of slides showing an attractive and an unattractive black female, as previously judged by both white and black college students. Again, the babies looked much longer at attractive faces.
Finally, 19 boys and 20 girls, all 6 months old and almost all of them white, viewed eight pairs of slides showing the faces of 3-month-old boys and girls previously rated as attractive or unattractive by college students. Attractive baby faces drew signficantly longer looks, the psychologists report.
Further studies must explore whether infants take attractive faces as “best examples” of a face, the investigators claim Langlois and a coworker recently reported that attractive faces may possess features that approximate the mathematical average of all faces in particular population.

3.What can be inferred from the passage?
A.All babies, white or black, tend to share with the college students the preference for attractive faces.
B.White babies prefer white faces to black ones.
C.Babies tend to get interested in the attractive faces of the opposite sex.
D.Beauty has something to do with a person’s age, race and sex

This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.
Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored (赞助) this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.
The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person"s actions. They realized that each of them can make a difference.

— Teaching Your K-12 Students to Type in 20 Minutes a Day
Typing is fast becoming an important skill in our world. Making this skill available to your students is very important. Just 20 minutes of the following activities per day will give your students the finger strength and keyboard knowledge they need to be ready to include typing in their learning programs.
Step 1 Knitting (编织): You can try various styles until you find the one that best suits your students’ abilities. Finger knitting is a great way to start! It helps students focus on finger strength. Knitting with needles is a little more challenging but will suit some older students. The more practice the fingers get the stronger they will become.
Step 2 Key board games: It helps your students become familiar with the keyboard. Students as young as four years old can practice finger placement, letter sounds and names using the keyboard of computers.
Step 3 Clay modeling: Many children develop the ability to be quick and skilful with their hands through creating clay models. The creative nature of this activity keeps children engaged for long periods of time. It helps keep fingers strong and supple.
Step 4 Lego (拼装玩具) building: Little fingers become strong when children pull apart little Lego time and time again. Because of the fun nature of this activity it helps build and does a lot to reinforce the ability to arrange things into an order — another important aspect in typing.
Choose an age-appropriate, interactive and engaging typing program. All students are different and with firm finger skills typing can be easily learned in 20 minutes a day with the use of a mixture of these different approaches.
小题1:All the following steps can make one’s fingers stronger EXCEPT ____.
A.Step4 | B.Step3 | C.Step2 | D.Step1 |

B.Different students have different results after following the activities listed. |
C.Only one activity can be used in a typing program for specific students. |
D.Firm finger skills are important for learning to type. |
With t he drought (干旱) continuing, the country is set to be forced to use purified (净化的) waste water for drinking, even though there is great opposition to the measure.
Queensland has become the first state to introduce the policy after a warning from its premier .
"I think in the end, because of the drought, all of Australia is going to end up drinking recycled purified water," said Peter Beattie.
"These are difficult decisions, but you either drink water or you die. There"s no choice. It"s liquid gold, it"s a matter of life and death."
Beattie said Australia"s second largest state would become the first to use recycled water for drinking.
Water is recycled in Britain and parts of northern Europe along with the US and Israel.
But Australians have never liked the idea.
To try to change the way Australians think, Prime Minister John Howard and Environment Minister Malcolm Turnbull have adhered to Queensland"s move.
"I am very strongly for recycling and Mr. Beattie is right and I agree with him completely," Howard said.
“Australian cities, all now facing water shortages because of the worst drought on record, must start to use recycled water.” added Turnbull, "All of our big cities have to widen the range of water sources to include sources which are not dependent on rainfall."
小题1:What is the text mainly about?
A.Continuing drought forces Australians to drink recycled sewage |
B.Australians face the choice of life and death |
C.Premier Beattie is worried about his people’s health |
D.We should avoid drinking recycled water to keep healthy |
A.Nobody disagrees to the idea of drinking recycled purified water |
B.Australia"s second largest state has become the first state to introduce the policy |
C.No other countries but Australia decide to drink recycled water |
D.The drought is the worst one in the droughts recorded in Australian history. |
A.Australians have never like drinking purified waste water |
B.Australians should develop more water sources to live through the hard time |
C.Australians can’t depend upon rainwater , which is not suitable for drinking . |
D.Australian government has no ability to solve the problem of water shortage |
A.disliked | B.gone against | C.supported | D.doubted |
A.he gives orders to drink purified waste water |
B.It is painful for him to see his people drink recycled sewage |
C.If the decision is made, people won’t survive the drought |
D.It’s up to you to either make a life or death decision |
Now I am sure that you know which schools are considered the best in the country. So I will tell you about which states I believe are the best to live in.
California is a nice state. Northern California specifically has very good weather. Los Angeles in southern California is another story though. Life in LA is full of excitement and fast, and sometimes—dangerous. As for me, I enjoyed the history and culture. The weather is not as perfect as California, but it is still quite nice. My favorite area of America is the Mid-west. Middle America, I think, is home to the true American sense of values. In addition, there are many good universities there.
Also, you need to think about your likes and dislikes and then research the various states. You like sunshine and hate snow? Then you probably won’t like the Midwest or even the Northeast. Open space, nature and peace and quiet? Then you should stay away from America’s larger cities. Are you interested in government? Then Washington D.C. is the only place for you. Whatever you decided put some thought into it. The place you live could be the difference between a great study abroad experience and a state of great suffering on earth.
