The Earth tilts(倾斜) when it travels around the Sun. It always keeps the same tilt. When one part of the Earth leans toward the Sun, it gets more sunlight. This place has summer. At the same time, the other part leans away from the Sun. It gets less sunlight and has winter. Spring and autumn come when the Earth is between these two positions. The sunlight is not too strong or too weak. The Earth takes about one year to finish one trip around the Sun. That is why we experience four seasons in a year. Different places have different seasons. The tilt of the Earth, not the distance to the Sun, brings us warm summers and cold winters. ( )1.Many people think seasons come because ______. A. the Earth tilts B. the Earth gets closer to the Sun C. the Sun moves around the Earth D. the Earth has more water ( )2.When a part of Earth leans toward the Sun, it has ______.
