Entity Framework查询生成大量的子查询，如何避免？求救

        private async Task<QuotationDto[]> GetEntitys(int pageIndex, int pageSize)
        {
            var entitys = await Db.Quotations.Where(x => x.IsDelete == false && x.IsPass).OrderByDescending(x => x.CreatedDateTime).Select(x => new QuotationDto
            {
                ProductName = x.Name,
                Id = x.Id,
                Price = x.YouPrice,
                UserName = x.UserName,
                Address = x.ProvinceText
                + x.CityText
                + x.CountyText
                + x.TownText
                + x.VillageText,
                RangeTime = EntityFunctions.DiffSeconds(x.CreatedDateTime, DateTime.Now)
            }).Skip(pageIndex * pageSize).Take(pageSize).ToArrayAsync();
            return entitys;
        }
