河南省信阳高级中学2018-2019学年高二上学期英语开学考试试卷
I always wondered how people would react if I tried to approach a total stranger for help in a busy place like a street corner or in a noisy mall. I have always hurried past a stranger who tried to catch my attention in a busy place or when I am rushing around.
Yesterday, I was in a busy shopping mall buying a large piece of luggage because I just had the time to do it after many days of planning. After the purchase in one of the large shops, I picked up my phone from my pocket to call my driver waiting in the parking lot but my phone was dead.
I then requested the shop assistant who had just sold me the luggage to ring the number of my driver for me and she replied that it was the shop policy that they cannot use mobile phones while working in the shop.
I got out of the shop onto the busy street in front and approached a young mother with her two kids to make a request. As soon as I said “Excuse me, madam”, she grabbed both her kids and ran. I felt like a kidnapper.
I stood there, wondering how many times I had reacted to strangers like the young mum. I stood there in the busy street with people rushing by, looking at their faces to see if there was a sign of kindness on their faces.
I saw a man pretty shabbily dressed. He seemed to have noticed me and I just stopped him expecting him to rush past. My request escaped the lips. He immediately called the number of my driver and waited till my car came to be sure I was picked up, and he turned around before I could thank him adequately and was gone. I was surprised by his kindness and hope I will do likewise to strangers who try to catch my attention from now on.

Hot Air Balloons
| A hot air balloon is made up of 3 main parts:
The Envelope The actual fabric balloon which holds the air.
The Burner The unit which pushes the heat up into the envelope
The Basket Where the passengers and pilot stand |
The basis of how the balloon works is that warmer air rises in cooler air. This is because hot air is lighter than cool air as it has less mass per unit of volume. Mass can be defined by the measure of how much matter something contains. The actual balloon has to be large as it takes a large amount of heated air to lift it off the ground.
The burner uses propane gas to heat up the air in the envelope to move the balloon off the ground and into the air. The pilot must keep firing the burner at regular intervals throughout the flight to ensure that the balloon continues to the stable. Naturally, the hot air will not escape from the hot at the very bottom of the envelop as firstly, hot air rises and secondly, the floating power keeps it moving up.
To move the balloon upwards, the pilot opens up the propane value which lets the propane flow to the burner which in turn frees the flame up into the envelope. It works in much the same way as a gas grill: the more you open the valve, the bigger the flame to beat the air and the faster the balloon rises.
The “Parachute Valve” at the very top of the balloon is what is used to bring the balloon down towards the ground. It is a circle of fabric cut out of the top of the envelop which is controlled by a rope which runs down through the middle of the envelope to the basket. If the pilot wants to bring the balloon down, he or she simply pulls on the rope which will open the valve, letting hot air escape, decreasing the inner air temperature. This cooling of air causes the balloon to slow its rise.
The pilot can operate horizontally by changing the vertical position of the balloon because the wind blows in different directions at different altitudes. If the pilot wants to move in a particular direction, he or she simply arises and falls to the appropriate level and rides with the wind.
