Directions: Read the following passage, and answer the questions according to the information given in the passage.
Elephants and people are in competition for space. In much of Africa, elephants are now put in national parks. Elephants suffered a serious and steady decrease in number in the 1970s.This was the same time when scientists were beginning to learn a great deal about elephants and their behavior. Studies through the 1980s and into the 1990s showed a lot about their sounds and methods of communication.
In Kenya alone, in the 1970s and 1980s, the elephant population decreased from 170,000 t0 25,000. The sharp drop in number was the result of poachers (偷猎者) illegally killing elephants for their ivory. The price of ivory went up from $ 3 a pound to $ 50 to $ 100 a pound. Africa became very attractive to poachers. Bull elephants carried larger tusks (象牙) , so they were more often killed. With males gone and older females killed by poachers as well, there were many young elephants unable to benefit from the wisdom of the older females and matriarchs, who lead the herds.
Kenya took a stand that international trade in ivory was officially forbidden, and $ 3, 000,000 worth of confiscated (没收的) ivory was burned in Kenya. The following year, only 50 elephants were lost to poachers in Kenya instead of 3,000. But Kenya has the fastest growing human population in the world. People throughout Africa won’t tolerate elephants eating their crops and destroying their livelihoods. In South Africa, elephants live behind the fences of national parks. In some parts of Africa, big-game hunters pay a lot of money to hunt elephants. This keeps their numbers down, and the money goes toward conservation. In Kenya, there are some attempts at birth control to keep the elephant population in manageable numbers to reduce conflicts with people.
Faced with a growing human population, elephants are losing the battle for space. It’s unlikely, though, that they will become extinct(绝种的). They will live in natural parks that bring tourists to Africa as well as India and other parts of Asia. The money from tourism will help elephants to survive.What’s the reason for elephant population decrease? ( No more than 8 words)

Write NO MORE THAN THREE WORDS for each answer.
Every person needs energy to go about the day and continue to function correctly. To get this energy, you eat, and your body changes the food into the nutrients and energy you need to survive. Your metabolism (新陈代谢) is directly related to how quickly and efficiently your body creates this energy, and if it takes too long, the food gets stored as fat. A slow metabolism will leave you with less energy and more weight than you probably desire.
Your basal metabolic rate (基础代谢率) is the amount of energy your body consumes while you're resting. When people say they have a slow metabolism, they mean they have a slow basal metabolic rate. Increasing this number is possible through exercise and muscle building.
According to Metabolism-Advice. com, as your age, your basal metabolic rate will lower as your body begins to deteriorate (衰退). At the age of 30, your body will stop producing the high levels of growth hormone it previously produces. Your body senses that it's done growing at 30, so it uses the resources elsewhere. Unfortunately, that means that your muscle will deteriorate more rapidly than before. While you can’t block age's effects or your metabolism, you can fight against it with regular exercise that builds muscle.
Although muscle deteriorates quicker with age, a lack of exercise will hurt your metabolism at any age. The muscle developed during exercise is vital to maintaining a healthy body with a normal basal metabolic rate. Therefore, while cardiovascular(心血管的)exercise will burn fat during the work out, building muscle will wisely allow your body to use more calories to give you healthy energy instead of stored fat.
Another large factor that determines your basal metabolic rate is your eating habits. Metabolism-Advice. com suggests eating small meals every two to three hours. This will make sure that your metabolism is constantly working throughout your day. Another large factor is how healthily you eat. Taking in the required calories for your amount of daily activity will help keep your metabolism from lowering, but taking in too many calories may lead to fat.

A lot of people are afraid spiders（蜘蛛）–even the small ones. But a big tarantula（鸟蛛）is much more terrifying for many. Now, scientists in Sri Lanka have discovered a huge species of tarantula that’s about the size of a person’s face.
The first part of the spider’s scientific name, Poecilotheria rajaei, comes from the Greek words for “spotted”(poikilos) and “wild beast” (therion). Its species name, rajaei, comes from a local police officer who helped the team that discovered the creature. Poecilotheria rajaei has 8-inch long legs, and unusual spots colored gray, pink, and yellow.
Although it is very big, is there a real reason to be afraid of one? Maybe. This tarantula has enough poisonous fluid（毒液）to kill mice and small birds and snakes –but its bite wouldn’t cause the death of most humans.
Poecilotheria rajaei was first seen in 2009, when a villager in Sri Lanka found the body of a male and brought it to Ranil Nanayakkara, co-founder of Sri Lanka’s Biodiversity Education and Research organization.
An examination of the awesome creature proved that it was a type of tarantula scientists hadn’t seen before. So Nanayakkara carefully looked through the Sri Lankan forests to try to find more of the spiders.
It’s still too early to know whether this species is endangered. But researchers fear that the tarantulas’ natural habitat is slowly being destroyed.
“ They prefer old trees, but due to the widespread removal of trees the number has dropped,” Nanayakkara said in an interview.
Tarantulas have eight legs and two body parts. They are different from insects, which have only six legs but three body parts. Tarantulas have hairy bodies and are usually larger than other types of spiders. Some species of tarantulas can live up to 25 years.
While Poecilotheria rajaei is very big, the largest tarantula is the Goliath bird-eater (Theraphosa blondi). Found in the rainforests of South America, its legs can be up to 10 inches long. But don’t worry if you ever see one: Its poisonous fluid isn’t really dangerous to humans.According to the text, Poecilotheria rajaei _______.
