【题目】 Being a successful high school student requires both patience and motivation. Unfortunately, there are often many things that can make your success difficult. Here are some tips which can help you become a successful high school student.

Remember that school is important. It’s important to have fun and have lots of extra-curricular activities, but school study should always be your top priority (优先的事物). 1

Get involved at your school. You don’t have to be a superstar or a cheerleader to do this. 2 These may include current events, such as the basketball game held last Friday or attending school events like dances and variety shows.

Find a club to develop your interests. Not being an athlete is not an excuse for not having something to do after school. 4 Music? Join a band. If you’re not into any of your school’s clubs, advise your principal to start a new one. Most likely he / she will say yes.

Focus on yourself. Don’t compare yourself with others. 5 Every day you should only try to make yourself better, instead of worrying about how the girl sitting in front of you has nicer clothes or is getting better grades, etc. Ten years from now, this won’t matter.

【题目】 Natural selection is the process by which one type of animal within a species thrives because of certain characteristics that make it more likely to live than others in its group. The history of the peppered moth(灰蛾)is an example of the natural selection process.

In 19th century England, certain types of peppered moths were able to better blend(融合)into their surroundings. During that time period, great changes were happening in Great Britain. The Industrial Revolution was part of this change, and with it came air pollution. Natural selection often takes hundred or even thousands of years to occur. For the peppered moth, this process occurred comparatively quickly.

At the beginning of the Industrial Age, most peppered moths in England were light-colored and covered with black markings, although a few moths had dark-colored wings. Because the light-colored moths blended into the light-colored bark on the trees, they could not be easily seen by birds that would eat them. As the air grew more polluted, however, tree trunks became covered with soot(烟煤)and became darker. The light-colored moths became easy for birds to see against the dark tree trunks. Since the dark-colored moths now had the advantage, their numbers grew. Within 50 years, the peppered moth went from being mostly light-colored to being mostly dark-colored.

In the 20th century, the air cleared up, and the peppered moth population changed again. As tree trunks lighted due to less soot in the air, light-colored moths once again had an advantage. Their numbers increased as soot levels declined. Depending on their environment, the coloration of the moths helped them to be “naturally selected” to survive.

1In 19th century, what was one of the causes of great changes in Great Britain?

A.The surroundings.B.The Industrial Revolution.

C.The natural selection.D.The peppered moth.

2What can we infer about the peppered moth’s natural selection process?

A.The length of time was unusual.

B.The soot levels in England did not affect it.

C.The color of peppered moths changed at random.

D.It was a good example of environmental protection.

3What’s the difference between light-colored and dark-colored moths?

A.Dark-colored moths were originally easy to see on trees.

B.Both kinds of moths preferred the dark-colored trees.

C.Birds failed to see light-colored moths.

D.The color of moths was unimportant.

4Which would most likely happen if soot darkened England’s trees again?

A.Birds would eat fewer moths.

B.Moths would not be able to stay alive.

C.Light-colored moths would disturb people’s life.

D.The population of dark-colored moths would increase.

【题目】 Humans and elephants don’t always get along. In Africa and Asia, elephants damage infrastructure (基础设施), farmers’ crops, and natural habitat critical for other species. If an elephant becomes a problem, humans may kill it. So local people and conservationists are trying to find better ways to keep elephants away from sensitive places. Now, researchers think they have a good tool to stop elephants: honeybee pheromones (信息素).

“Elephants hate being stung () in the trunk, so it’s an extremely sensitive organ. Imagine being stung in your nose by a bee, and multiply that a few thousand times.” said Mark Wright, a professor of entomology at the University of Hawaii at Manoa.

Kenyan farmers have long known that if they hang live beehives around their farms, they will repel elephants. “The problem is logistical, how do you manage hundreds of thousands of hives, if you have a huge area to protect? And then the idea came up to look at the alarm pheromones, which are chemicals that the bee release to launch an attack on something that’s damaging the hive.” Because elephants have a highly developed sense of smell, Wright and his team thought they might be able to use the bees’ alarm signal to affect elephant behavior.

So the researchers tested out a synthetic blend (合成混合物) of chemicals that imitates honeybees’ alarm pheromones. In Greater Kruger National Park in South Africa, the team hung white socks treated with the synthetic mixture as well as untreated control socks around an elephant watering hole, and then observed the animals’ behavior. “Elephants are really curious organisms, they’ll walk along and see something like a sock hanging on a branch in the environment, and they’ll inspect it. And if it’s not treated with the alarm pheromones, they’ll pick it up, throw it around, try to taste it, things like that. And in the case of the treated ones, we found that they would show immediate signs of unease or uncertainty, and they’d eventually back off from them. Very seldom would they go to pick them up and play with them.” The study is in the journal Current Biology.

1What will the researchers do to prevent elephants from damaging human’s habitat?

A.Kill them.B.Scare them away.

C.Apply honeybee pheromones.D.Rebuild a new ecosystem.

2What does Mr. Wright think of Kenyan farmers’ method if it’s applied to a huge area?

A.Scientific.B.Flexible.C.Awesome.D.Impractical.

3Why did the researcher conduct the study?

A.To confirm what they thought.

B.To attract the elephants’ attention.

C.To preserve the elephants’ habitat.

D.To test out honeybee’s alarm pheromones.

4What’s the main idea of the text?

A.Elephants and humans don’t get along well.

B.Honeybee pheromones can keep elephants away.

C.Elephants have a highly developed sense of smell.

D.Honeybees release pheromones to launch attacks.
