Pack tightly. Packing loosely wastes precious space and causes clothes to wrinkle.

Use a divider shelf to separate accessories, irregularly shaped items, and shoes from your garmeats.

You may also want to stuff your shoes with underwear or socks so they won't be crushed during your travels.

Suits, dresses, shirts, and blouses should be packed in a plastic dry cleaner bags to limit wrinkling.

Roll pajamas, nightgowns, sweaters, and other casual wear to fill small spaces when possible, BUT don't cram your suitcase full. If you have to force your luggage to close, remove a few items to prevent broken hinges or zippers along the way.

Try the "interweaving method" of packing for your next trip. Drape longer garments such as dresses and pants around the suitcase with the ends hanging over the sides. Then fold shorter items such as jackets, shirts and blouses around the longer garments so that the clothes cushion each other. Placing a piece of tissue paper between each layer of clothing will help prevent wrinkling.

Pack each item one at a time in a clockwise direction. When you have filled the bottom of the suitcase, begin the next layer packing each item in a counter clockwise direction. In this way, you will form. one complete package of your clothes, eliminating wrinkles and securing all of your contents.

Always carry your travel documents, medication, jewelry, traveler’s checks, keys and other valuables in your hand luggage. These items should NEVER be packed in luggage you plan to check.

To avoid travel delays when you depart check with the Transportation Security Administration to verify that the items you are carrying on the plane are allowed onto the aircraft. You'll find a complete list of prohibited items on TSA website.

Which of the following statements is not true according to your reading?

A.Placing a piece of tissue paper between each layer of clothing will help prevent wrinkling.

B.You must stuff your shoes with underwear or socks and other valuables so they won't be crushed during your travels.

C.Pack each item one at a time in a clockwise direction.

D.Check with the Transportation Security Administration to verify that the items you are carrying on the plane are allowed onto the aircraft.

第3题

Ask someone what they have done to help the environment recently and they will almost cert
ainly mention

recycling. Recycling in the home is very important, of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.

The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a third of a

typical household&39;s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.

Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it

for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more

than they need. However, few of them are coming round to the idea that this cannot continue, encouraging

customers to reuse their plastic bags, for example.

But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.

There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary

materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.

What does the underlined phrase "over-consumption" refer to?

A.Using too much packaging

B.Recycling too many wastes

C.Having more material than is needed

D.Making more products than necessary

The author uses figures in Paragraph 2 to show().A.the tendency of cutting household waste

B.the increase of packaging recycling

C.the fact of packaging overuse

D.the rapid growth of supermarkets

According to the text, recycling().A.means burning packaging for energy

B.helps control the greenhouse effect

C.is the solution to gas shortage

D.leads to a waste of land

What can we learn from the last paragraph?A.Needless material is mostly recycled

B.Fighting wastefulness is difficult.

C.People like collecting recyclable wastes.

D.The author is proud of their consumer culture

What can be inferred from Paragraph 4?A.Unpackaged products are of bad quality

B.Supermarkets care more about packaging

C.Other products are better packaged than food

D.It is improper to judge quality by packaging
