10、ge 1 Amazing Facts about Blue WhalesBlue whales are the largest creature ever to have lived on Earth. Here are some amazing facts and figures about these incredible creatures.How much does a blue whale weight?Female blue whales weigh more (190,000kg) than males (150,000kg). At around 2,700kg newborn

11、 blue whale weighs about the same as an adult hippopotamus(河马). The heart of a blue whale can weigh 450kg.How long does a blue whale live?The oldest known blue whale was around 110 years old; however, up to 90 years old is thought to be more normal.What does a blue whale eat?Despite their enormous(h

12、uge) size, they feed on tiny shrimp-like crustaceans called krill (磷虾)(as many as 40 million every day) which they scoop(舀) up in huge mouthfuls and sieve(筛) from the water using their baleen(鲸须).They have loud, deep voices and can communicate with other whales hundreds of miles away. The sound they

13、 make can reach up to 188 decibels (anything over 120-130 is painful for humans). Only the sperm whale(抹香鲸) makes a louder sound.The tongue of a blue whale weighs as much as an elephant and is so big a whole football team could stand on it.Most blue whales migrate(迁徙) to cold waters to find food and

14、 to warmer waters to breed. Females usually give birth to a calf(幼鲸) once every two or three years after a gestation(怀孕) period (pregnancy) of up to 12 months.A blue whale calf can drink 250 litres of its mothers milk every day. It is weaned(断奶) after around six months.The major blood vessel(血管) of

15、a blue whales heart is so big that a baby could crawl(爬行) through it.During their four-month migration, they eat very little, surviving mostly on reserves of blubber(鲸脂).Although hunting blue whales has been banned(禁止) for a long time, they are still an endangered species with an estimated(估计) world

16、wide population of 10,000 - 25,000.Passage 2 Major Threats to Blue WhalesWhaling(捕鲸) may have stopped but many other human activities still threaten their existence.The main threats .Hunting though they are not currently hunted, whalers are constantly pushing for reprieve(延缓) and pose a constant ris

17、k, trying to conduct so-called sustainable(可持续的) hunting. Pirate whaling is also a threat.Pollution increasingly troubled by the build-up of toxic(有毒的) chemicals from plastic, litter and oil spills(泄漏) in their systems, the health and fertility(生育力) of large whales could be seriously made up of poll

18、ution.Noise pollution blue whales rely on sound to navigate(导航) and communicate. Noise from military sonar(声纳), oil and gas drilling(钻) and exploration and shipping can seriously disrupt(打扰) them and even cause them to strand(浅滩).Fishing nets and gear(渔网渔具)- trawl nets are pulled by boats, static ne

19、ts hang in the water; both catch everyone and everything in their path and are a massive threat to blue whales.Vessel strikes(船只撞击) the number of boats on the ocean is increasing all the time. Though they are large, blue whales are relatively slow and are vulnerable(脆弱的) to strikes by many kinds of

20、vessels.Irresponsible whale watching their size and fame make blue whales very popular with whale watchers, but unfortunately in some parts of the world boats are getting too close and interfering(扰乱) with their lives and natural behaviours.Passage 3 How China Protects Giant Pandas - Pandas Now NOT

21、Endangered!The government has adopted a three-pronged approach to promote the survival of the giant panda as a wild animal species:1. Habitat Protection - 13 Giant Panda Nature Reserve AreasThe most important work to save the giant panda is to protect their habitat. Without this, pandas could only s

22、urvive in captivity(圈养).To protect giant pandas habitat, China government has set 13 panda nature reserve areas. In the areas,farming fields have been left to grow back as forest. Trees and bamboo have grown well, and habitat are recovering. Also farming practices around the forests have been reduce

23、d or separated from the reserve areas.According to government research in 2015,habitat for giant pandas has grownby about 2,720 km2, (almost the area of Yosemite National Park), compared to in 2003. At 25,770 km2, panda habitat is now almost twice the size of Serengeti National Park.In the reserve a

24、reas,conservation stafflive and work to rescue sick or starving pandas, and to stop smugglers(走私者) from hunting giant pandas.2. Captive Breeding - Research, Education, and Returning to WildIn 1980s, much of the bamboo on the Qionglai Mountains (the giant pandas main habitat area) died. Thus manygian

25、t pandas were starving, and were rescued to Chengdu Zoo.In 1987, to separate the research work, theChengdu Panda Centerwas established for giant panda research. The original six starving giant pandas have bred more than 150 pandas since then!Unlike ordinary zoos or attractions, panda research center

26、s focus onresearch and breeding. There are several panda centers around Chengdu to breed(喂养) pandas, educate people about protecting pandas, and to do research to help save this lovely species.Some research centers, like Dujiangyan Panda Valley,prepare the captive-bred pandas to be introduced into t

27、he wild.3. Laws and Stiff Penalties - Over 10 Years in Jail for Hunting or Smuggling Giant PandasThe giant panda is known as the national treasure of China.

28、and smuggling(走私) of their pelts and body parts, so Chinas government establishedlaws and severe penaltiesto protect giant pandas from hunting and smuggling.Passage 4 Why the Giant Panda was Endangered - Mainly Habitat ReductionThere are many reasons that caused giant pandas to be endangered. But th

29、e main reason wasdisappearing habitat. Habitat reduction (peoples logging and farming practices) Food decreased (bamboo dying off) Low reproductivity (1 cub in 2 years) and low survival rate for panda cubs Poaching(偷猎) and hunting1.Giant panda habitat was reduced gradually by farming and forestry. A

30、s Chinas population increased around giant pandas habitat theforest was cut down by hill farmers.2.Because their habitat was decreasing, giant pandas had to move up to higher mountain areas, which had few bamboo species. When these species declined(下降),giant pandas didnt have enough food.3.Giant pan

31、das only give birth to 1 or 2 cubs at a time. However, especially in a tougher environment, they usually cant raise both. They usually get pregnant(怀孕) every two years at most, but the decreases in their population made it increasingly difficult for females to find a mate, soreproductivity(繁殖力) decr

32、eased.4.After giant pandas were discovered by foreigners in the late 1800s, more werepoached, and many more wereshot for their fur. Though poaching stopped after the 30s due to war and the new regime, locals continued to hunt pandas for food and fur, and smuggling was again rampant(猖獗的) in the 80s.The giant pandas couldnt adapt quickly enough to their environmental changes and human persecution, and were declaredendangered in 1990.第 7 页 共 7 页
