1 . The number of buses, taxis and other transportations on Kenya’s roads is growing every day.
Now, the country’s first electric-powered motorbike is being made. The motorbike is designed(设计)to cut down on pollution. It’s much cheaper so that most of people can afford it.
Most motorbikes used in Kenya depend on gas as fuel(燃料), but not this new motorbike. Its energy comes from sunlight.
Three university students developed the new motorbike. It receives the sun’s energy, stores it in batteries(蓄电池)and uses it to charge(充电)the electric motorbike.
Robert Achoge is one of the student inventors. “Our hope is that by the fifth year, we will be able to cover the whole Kenya with the electric motorbike in order to improve the environment and provide affordable transport.”
The students have set up a fueling station for the motorbikes in Nairobi. Riders can charge the motorbikes in the station. The small battery can run for 70 kilometers when they’re fully charged. Once the power is used up, the motorbike has to return to the fueling station while another charged battery is connected to the motorbike. The US African Development Foundation is providing some money for two solar-powered charging stations in the Kenyan port of Kisumu.
Each motorbike costs about $700. One motorbike rider says the new motorbike costs less to ride than motorbikes running on traditional fuel. “When talking about buying fuel, there is no need. It’s basically good for everyone. Even though you won’t carry quite a heavy load, you can go with it anywhere.”
A Nairobi dealership is selling the motorbikes. Businessman Kennedy Kusimba hopes they will become popular. “We also know they are more reliable, compared to the gas-powered motorbikes. They are more useful and they will last longer.”

9 . Some students study hard by cup after cup of coffee, what is more, the test stress(压力)almost makes them crazy(疯狂). But when you want to review as many books as possible to be ready for your test, don’t forget your health. After all, if you’re sick during your tests, every effort(努力)might be useless. Here are some tips on food, drinks and sleeping for you.
Food and drinks
The most important thing to remember about eating and drinking is to do just that: eat and drink. Never try to work when you are very hungry. Always do your homework before you get too tired.
1) Eat healthily and regularly
A banana or orange with some yogurt will fill you up better than junk food. Don’t break your food habits too much. Eat a healthy breakfast, lunch, and dinner at the same time you always do. Don’t eat take-out and junk food.
2) Drink more water
Drink water, and then drink some more. Nothing else will help your mind keep clear and keep your energy(能量)levels high. Sugary(含糖的)soft drinks will do badly for your health. You can also add some fruits like lemon to your water.
3) Drink less coffee and energy drinks
Caffeine(咖啡因)is so popular. Everyone could refresh(振奋)himself by using a cup of coffee, but drinking too much will make you uncomfortable, can’t sleep well.
Sleeping
All of that studying during finals week will be for nothing if you don’t get enough sleep.
1) Make sure about sleep time
Don’t wait until late in the evening, or the homework will seem much harder than it really is.
Arrange(安排) your time properly(合适地)before final exams. You know your body, your study habits, and your finals schedule(时间表), so make a plan according to these.
2) Take a rest
Relax yourself after an hour’s work. Put your head down or lie down and set an alarm for half an hour to get some quick power sleep to add(增加)energy.
3) Keep your environment(环境)relaxing
Play some light music to help yourself fall asleep and give your body enough rest.

10 . Why are dogs our best friends. Maybe because they can understand our words much better than we thought, according to a study in Hungary. It found that dogs understand not only what we say, but also how we say it.
“The results were very exciting and very surprising.” Said the researcher Attila Andies, from Eotvos Lorand University in Budapest.
For the study, the researchers first trained 13 dogs for months. The dogs had to sit quietly inside machine, so that the researchers could check their activity.
Then the researcher put headphones on dogs and played people’s voice to them. There were four different voice. Some were positive words,such as “well down”, or neutral(不带感情色彩的) words like “however”. The words were also in different tones(音调). Some were positive and some were neutral.
Brain scans(扫描)showed that the dogs could recognize(辨认)words, as well as the tone of words, much like people do. The positive words with a positive tone brought the stronger activity in their brain’s reward centers(反应中枢).
“It shows that for dogs, a nice phrase can work very well as a prize, but it works best if both words and tones match.” Said Andies.
They also found that dogs deal with meaningful words with the left side of the brain and tones with the right. Human brains work in the same way.
It gave us a new understanding of language,said Andies. That is, not only do humans understand the meaning in words, other species(物种)do too.
