Many people like to eat at a favorite restaurant on their birthday. 71 Here are the tips about how to eat for free on your birthday.
Notice promotional (促销的) cards or signs at restaurants for their e-club or online notification of special offers. Sometimes it is called a birthday club. In some cases they ask for your email address and at other times, you register online from your own computer. 72
If you don’t know whether your favorite restaurant has an e-club, look them up online. Just search their name if it’s a chain. Look over the webpage for anything that says SIGN UP or JOIN. It may call it an e-club.
You will receive e-mail advertisements from them. 73 if it asks for birthday and anniversary dates when you sign up, then the restaurant usually will send you a personal coupon and invitation for that event.
Check your e-mail the week leading up to your birthday. All the e-clubs that you signed up for will be sending their invitations.
Read the fine print on all the offers before deciding where to eat on your birthday. Some are only on the exact date. 74 There may be other requirements, like free dessert when you buy an entree (主菜).
Choose the most inviting offer or over several days, take advantage of free dining opportunities. __75
| A．Anyway, look around for these offers and get signed up. |
| B．However, others may be for any time over a two-week period. |
| C．But how can we eat better in a free restaurant? |
| D．It would be an even greater treat if the meal or part of the meal were free. |
F. Often the advertisements will include discount coupons(优惠券).
G. So don’t go to such restaurant.

Before going outside in the morning, many of us check a window thermometer(温度计)for the temperature. This helps us decide what to wear. _____76____. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.
Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.
Both systems use the freezing and boiling points of water as their guide._____77_____ .
The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube._____78______.
First. Take a clear glass juice bottle that has a cap ; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.
______79______.
Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.
______80____.
As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.
|
A．We use and depend on thermometers to measure the temperature of many other things in our daily lives. |
|
B．Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled. |
|
C．Now that you know this rule you can make a thermometer of your own that will work. |
|
D．The water will rise in the straw. As the temperature of the air goes up, the water will |
expand and rise even higher.
E．They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.
F．Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal把..粘住) them together.
G．People use thermometers which are made by themselves when travelling around the
world.
