Do we have summer wen the earth gets closer to the sun?

No, summer occurs in various regions of the Earth when those areas are tilted toward the sun, not because the Earth is closer to the sun. The Earth's orbit is an ellipse, but the variation in distance is minimal compared to the effect of axial tilt. This axial tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.
