 Saving energy means saving money. Homeowners and renters know this basic fact, but they often don't know what kinds of adjustments they can make in their homes and apartments that will result in savings.
 For those willing to spend some time and money to reap long-term energy savings, an energy audit is the way to go. An energy auditor will come into your home and assess its energy efficiency. The auditor will pinpoint areas of your home that use the most energy and offer solutions to lower your energy use and costs. Trained energy auditors know what to look for and can locate a variety of flaws that may be resulting in energy inefficiency, including inadequate insulation, construction flaws, and uneven heat distribution.
 There are quicker and less costly measures that can be taken as well. One way to save money is to replace incandescent lights with fluorescents. This can result in a savings of more than 50% on your monthly lighting costs.
 When it's time to replace old appliances, it's wise to spend a bit more for an energy-efficient model, and be sure that you are taking advantage of energy-saving settings already on your current refrigerator, dishwasher, washing machine, or dryer.
 Windows provide another opportunity to cut your energy costs. Caulk old windows that might be leaky to prevent drafts, and choose double-paned windows if you're building an addition or replacing old windows. Most areas of your home or apartment offer opportunities to save energy and money. The results are significant and are well worth the effort.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
 A new British medical instrument is about to change dramatically our ability to recognise disease hidden inside the body. It is called the magnetic scanner, and it gives information about the body which current machines, such as the brain scanner and the more recent body scanner, cannot provide. And unlike existing machines, the new machine does not use X-ray radiation waves, which make it much safer for patients.
 Unlike existing scanners, a magnetic scanner can show the side or the back of a suspect part of the body. Used on, for example, a lung with suspected damage, it can turn the image of the lung to give a series of different views. The image is not simply worked out in the computer's "imagination": the magnetic scanner actually examines every side of the lung. When examining the softer part of the body with existing scanners, doctors frequently have to use a "contrast medium" to make a muscular organ show up to X-ray waves, the usual "contrast-medium" given to patients before a stomach X-ray scan takes place is harmless, but for some brain scans so that it passes into the brain. This is unpleasant and painful and it can be dangerous. The magnetic scanner needs no "contrast medium".
 The new machine can also see in greater detail than ever before. Growths of all kinds show up clearly on the brain and so do the dead patches which are the signs of the disease, multiple sclerosis. Until now patients complaining of double vision or an inability to control their muscles from time to time could be suffering from some much more easily cured disease and a brain scanner could not distinguish between these with certainty. The doctor can now definitely say whether or not cancer of multiple sclerosis is present. Previously, these diseases have been missed and patients have been given false information about their health. The technique is still improving with great speed: pictures produced a couple of years ago look very simple compared with those of today.
Question 44: What does the new magnetic scanner machine do?
A. It sends waves round the diseased part of the body.
B. It can look right through a diseased part of the body.
C. It uses a computer to "imagine" different views of the body.
D. It looks at a diseased part of the body from all directions.
Question 45: The word “it” in line 10 refers to......
A. The muscular organ	B. The brain scan	C. The stomach X-ray	D. The X-ray wave
Question 46: What disadvantage do existing machines have?
A. It is often necessary to use a contrast medium.	B. The contrast recorded are too strong.
C. Patients need an injection before they are used.	D. The X-ray waves are sometimes painful.
Question 47: The machine is useful in identifying the disease multiple sclerosis, because it shows......
A. dark spots in the eyes.	B. damage to muscles.
C. dead areas in the brain.	D. cancer like growths.
Question 48: In what way is the new machine an improvement?
A. The techniques involved can be learned quickly.
B. It can cure some diseases much more easily.
C. It can show all the details of a diseased part of the body.
D. It will never give a double view.
Question 49: "Sclerosis" means......
A. bronchitis.	B. a disease hardening soft parts of the body
 C. tuberculosis.	 D. a disease that causes indigestion.
Question 50: The word “missed” in live 17 is closest in meaning to......
 A. failed to do	 B. notied something is lost
C. felt sad because of the absence	D. escaped from doing
