【题目】

Scientists have discovered a new kind of invisible ink. It’s called water. And all you need for this secret-messaging ink to work is to write with it on a super-hi-tech piece of paper coated with special chemicals. 1 It shows up darker than the surrounding paper under UV(紫外线的) light.

When the message has been read and needs to be hidden again, get out your hairdryer, and blow some warm air on the paper. 2

Using hot air from a hairdryer for 15-30 seconds, you were able to reuse the special paper up to 30 times because the heat reorganized the chemical structure of the paper coating. 3

The invention was made by a group of scientists in China, led by Qiang Zhao of the Institute of Advanced Materials, Nanjing University of Posts and Telecommunications.

Although much of modern communication is digital(数码的), there are still some situations in which it is important to send messages on a piece of paper, such as when the people don’t have Internet. 4 But the problem has always been how to get rid of a message once it has been shown so no one else can read it.

5. To use it, write with the lemon juice on ordinary paper, iron() the paper with a hot iron and the hidden message will appear. The downside(缺点) is that the paper has to be destroyed to hide the message so no one else can read it.

A.How to make the invisible ink? Follow the steps.

B.Invisible inks have long been used to send secret messages.

C.Without the heat, the message stayed visible for up to three months.

D.Previously, the most readily available invisible ink was lemon juice.

E.Shine a UV light on the coated paper and the water message becomes visible.

F.Then the message will be gone and the paper can be reused, which keeps costs low.

G.Putting water on the paper broke up the structure of the chemicals it was coated with.

【题目】Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.

If you can’t seem to catch enough Z’s during the week, you’re not alone. But bad things happen to your body when you’re sleep-deprived, not least of which is weight gain. Well, here’s some good news: Sleeping in on the weekend to make up for sleep lost during the week is 1 with lower body mass index (BMI), according to a study published in the Oxford University Press journal Sleep.

The researchers, a collaboration of scientists based in Boston, Massachusetts, and the Republic of Korean, sought to determine if what they refer to as “catch-up sleep”2 body mass index (BMI) in the general population. To do so, they conducted face-to-face interviews of a random sampling of 2,156 adults, comparing their sleep habits with their BMI scores. The 932 participants who slept in – “catch-up sleepers” (people who sleep longer on the weekend than on weekdays by approximately two hours) had a(n)3 lower BMI than the other subjects. What’s more, every additional hour of catch-up sleep was linked with a decrease in BMI.

As to why sleeping in on weekends can lead to weight loss, one of the study co-authors, Robert Thomas, MD, MMSc, of the Division of Pulmonary, Critical Care and Sleep Medicine, Department of Medicine at the Beth Israel Deaconess Medical Center in Boston,4 Reader’s Digest of the “substantial(大量的) experimental and epidemiological(流行病学的) data that short sleep contributes to weight gain.” He notes, “our best 5 as researchers are that there are balances to be kept, and the body can adjust and 6 within reason. Catch-up sleep allows the basic balance to be maintained.”

Although the study showed significant differences in BMI with the 7 of two or more hours of catch-up sleep, Dr. Thomas points out that there are “substantial individual differences,” such that the benefit we get from those extra hours will vary 8 on how much sleep each of us generally needs. “To determine your optional sleep, you can track the time spent sleeping on nights when there is no need to wake up to an alarm,” suggests Liza Baker, a health coach at Simply Health Coaching. That tells you about how many hours of sleep your body likes to get, since it 9 greatly across the population, from just 4 to 5 hours to 9 to 10 hours.

So can you actually lost weight by sleeping in on the weekend? Only if you’re paying off a sleep 10 from the week, according to the result of this study. It helps if you’re also eating less, Dr. Thomas adds.
