If you travel in New Zealand, you may find some very interesting things. It is called “New Zealand Four Strange Things”.

	Have you ever seen that cows are lined up? New Zealand is so large. It is impossible for people to milk cows by hand. So the farmers trained the leading cow to take the cows to the milking station twice a day. The leading cow has a sensor（传感器）on its head. When it is time for milking, the sensor warns the leading cow to take the lead.
	Horses are mainly raised for viewing（观赏）and racing, so the coat color is very important. Wearing sunscreen（防晒）clothes on horses can avoid the harm from the sun. The clothes on horses are filled with weights that are the same weight of the rider. When the weights are replaced by the rider during the race, “________” just like the sportsman running with sandbags.
	Sheep in New Zealand used to have tails. Because they poop（排便）when they’re born, grass flies are interested in them. Grass flies lay their eggs in the tails of the baby sheep, causing illness and death. Then people tie their tails. As time passes, the sheep become tailless. This improves the survival rate（成活率）.
	New Zealand’s alpacas（羊驼）were introduced from South America. They are quite different from two-humped camels（双峰驼）. An alpaca weighs about 55 kg to 65 kg. Its shape is like a sheep. Only one grown-up male（雄性）alpaca can be found in each group. It is the leading one. Alpacas are gentle, clever and human.
