1. B - bloom earlier (nở sớm hơn)
2. D - toward the poles and up mountainsides toward higher elevations (về phía các cực và lên các triền núi tới những nơi cao hơn)
3. A - species
4. C - the melting ice in the Arctic
5. D - 20 to 50 percent of species could become extinct. (20 đến 50% các loài có thể tuyệt chủng)
6. A - they may be endangered (chứng có thế gặp nguy hiểm)
7. B - easily damaged
8. D - the slow death of coral reefs, (cái chết từ từ của những rặng san hô)
9. A - the rising amount of carbon dioxide entering the ocean. (Sự tăng lượng khí C02 trong không khí ảnh hưởng đến đại dương và tăng nồng độ axit trong nước)
10. B - Effects of global warming on animals and plants (Ảnh hưởng của sự nóng lên toàn cầu đối với động vật và thực vật)
Giải thích:
1. Plants and animals will find it difficult to escape from or adjust to the effect of global warming, Scientists have already observerd shifts in the lifecycles of many plants and animals, such as flowers blooming earlier and birds hatching earlier in the spring.
2. With further warming, animals will tend to migrate toward the poles and up mountainsides toward higher elevations.
3. Species living in unique ecosystems, such as those found in polar and mountaintop regions, are especially at risk because migration to new habitats is not possible.
4. For example, polar bears and marine mammals in the Arctic are already threatened by dwindling sea ice but have nowhere farther to go.
5. Some scientists have estimated that 20 to 50 percent of species could be committed to extiction with 2 to 3 Celsius degrees of further warming.
6. Some species and even entire ecosystems, such as certain types of forest, many not be able to adjust quickiy enough and may disappear.
7. A, very large: rộng lớn
B, easily broken: yếu ớt
C, rather strong: khỏe
D, pretty hard: khá khó
8. Warmer ocean temperatures can cause coral to “bleach”, a state which if prolonged will lead to the death of the coral.
9. Also, increasing carbon dioxide in the atmosphere enters the ocean and increases the acidity of ocean waters
10.
Plants and animals will find it difficult to escape from or adjust to the effect of global warming.
With further warming, animals will tend to migrate toward the poles and up mountainsides toward higher elevations.
Projecting species extinction due to global warming is extremely difficult.
Ocean ecosystems, especially fragile ones like coral reefs, will also be affected by global warming.
