Part II 提高部分
一、阅读理解
Wildlife faces threats from habitat destruction, pollution and other human actions. Although protecting wildlife can seem difficult at times, even small actions in your own neighborhood can help protect many different animals. As the saying goes, "Think globally and act locally." You can protect wildlife for future generations.
Create wildlife-friendly areas in your backyard. When choosing your lawn and landscaping, choose native plants that can provide food or living places for native wildlife. This will also help cut down on pollution. Add bird or bat houses to your yard or garden to attract these species and offer places to them to live in.
Avoid disrupting (扰乱) the natural ecosystem in your area. Non-native plants or animals can destroy habitats, particularly if there is no natural predator (捕食性动物) to keep the species in a certain amount. They can kill or disturb native plants that provide food and living places for wildlife.
Practice a greener lifestyle. By saving water and fossil fuels, you will be helping to protect the wildlife around you. Take public transportation when you can, turn off electric devices when you’re not using them, take shorter showers and keep your heat at or below 20℃ during the winter. Become knowledgeable about what can cause global warming, which disrupts migration patterns and habitats.
Buy products that are wildlife friendly. Avoid products that are made from threatened or endangered animals. Keep in mind that some endangered animals are killed by traps, or hunters who are after other wildlife within the same habitat.
Talk to or write to policymakers about protecting wildlife. Write letters to a local newspaper. Discuss ways to help animals with friends and family members.
Limit the family size. Population growth is one of the major factors in habitat destruction. By living in established city limits and limiting the family size to around two children per family, the earth’s population will stabilize (稳定) and native habitats can be protected.
1.What's the main idea of the first paragraph
A.It is impossible to protect wildlife.
B.You can protect wildlife by taking small actions.
C.Protecting wildlife needs ideas rather than actions.
D.Humans are big threats to wildlife in fact.
2.What should we do to protect wildlife
A.Stop non-native plants and animals destroying the natural ecosystem.
B.Know more knowledge about wildlife.
C.Increase the number of the population in the world.
D.Write letters about animals to your friends.
3.Which of the following can be taken as a greener lifestyle
A.Planting native trees in your backyard.
B.Keeping the water above 20℃ when you are bathing.
C.Taking a bus when you are going out.
D.Only eating vegetables.
4.What’s the best title for the text
A.Why global warming affects wildlife
B.Whether we are friendly to wildlife
C.What makes wildlife endangered
D.How we can protect wildlife
二、七选五
How to get better pictures of wildlife
Go on nature observation
Animals make rewarding subjects for photography but are uncooperative models. ______1____. Observation will tell you which flowers attract the most bees, which trees are most popular among birds, and which ponds are frequented by frogs, allowing you to set up your camera at a site that has a good chance of success.
Become a part of the landscape
Rural animals are very likely to be frightened if approached by a person, ruining not only the chance for a great photograph, but also the likelihood of them returning to the same spot again. _____2_____ . By contrast, urban animals are more habituated (习惯的) to humans and will probably ignore you if you stay still for long enough.
_____3_____
Choosing one species to concentrate on is a great way to push yourself. Pick a species that is accessible in your local area, even if it is not the most attractive of creatures. Remember, you’re looking to create great images, not bad images of great animals. Getting to know that species well will improve your field craft skills, and telling its story will naturally suggest different images to try.
Don't be a fair- weather photographer
Shooting in the middle of the day while the light is bright is pleasant, but rarely produces the best images. _____4_____. Getting out after dark also brings other rewards. Many animals are more active at night, and newer cameras with high ISOs are making night photography more accessible than ever. _____5_____. See rain as an opportunity to get creative with reflection, as well as documenting behavior you wouldn’t see on a dry day.
A. Focus on one species
B. Remember to use your urban setting
C. Even the wet weather shouldn’t keep you indoors
D. To create great images, it pays to learn about their habits

G. Therefore, it' s better to choose a secret location and wait for the wildlife to come to you.

Save Cute Pandas
Not only is the giant panda a rare animal in China but also one of the rarest animals on the earth. As more and more habitats are being destroyed and most of the bamboo has been cut down, it is becoming more and more difficult for giant pandas to find food for themselves. So they are becoming extinct. To save giant pandas, our government has set up some nature reserves. But more funds and attention are needed to carry out this important rescue project.
