Thank you for your attention!

In nC1.9 Change default.aspx to be
<%@ Page Language="C#" MasterPageFile="~/MasterPages/ThreeColumn.master" AutoEventWireup="true"
    Inherits="NopSolutions.NopCommerce.Web.Default" CodeBehind="Default.aspx.cs"
     %>

At the top of default.aspx it already is that code. It is not work.
So how to make nopcommerce 1.9 to look like that: http://savepic.org/1348459.jpg

Make masterpage for default.aspx to ThreeColumn.master

if you did that already then go to admin section > Configuration > Global Settings > Choose last tab "Other" and find this:

Show mini-shopping cart: CHECK MARK and SAVE CHANGES

now you will be able to see mini shopping cart on your homepage

In order to make mini-shopping cart's position to the left go to ThreeColumn.master page

Inside this section:
<div class="master-wrapper-rightside-3">
        <asp:ContentPlaceHolder ID="cph3" runat="server">
...................
.......

you will see this:  

<nopCommerce:MiniShoppingCartBox ID="ctrlMiniShoppingCartBox" runat="server" />

cut it from there and paste it above inside this section:

<div class="master-wrapper-leftside-3">
        <asp:ContentPlaceHolder ID="cph2" runat="server">

....
