Three Things to Do Before You Are 18
Are you bored with your daily life? Here are some things you should try before you are 18.
★Learn to swim
Seriously, this is so important that it can save your life. If you can’t swim well, you won’t be able to dowater sports like waterskiing, surfing and diving. Even taking a boat trip will be dangerous for you. Make sure you do it.
★Try at least one kind of team sports
Being a good team player is an important skill in life. You can’t just think of yourself, but have to work well with other people. Other advantages of team sports like basketball, football and baseball are that they keep you fit and healthy, and they are also great fun. Teams usually have a good social life too—you’ll go to lots of parties and make many friends.
★Collect something
One of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you could collect things that make you remember what you have done, like cinema tickets for films you have seen or letters from friends. The best way to collect is to have a special album to put your collection in and to write what each thing means to you. That way you won’t forget.
1. The most important reason for learning to swim is that ________.
A. you might feel well
B. it can make you healthy
C. you might easily do lots of things
D. it can save your life
2. The writer tells us that one of the best hobbies is to ________ .
A. collect something
B. do some water sports
C. send letters to your friends
D. play basketball with your friends
23. The passage is mainly about ________before you are 18.
A. good habits to keep
B. skills to have
C. things to do
D. sports to play
B
Have you ever noticed that some people can eat what they want and stay in shape, while others carefully watch what they eat and still put on weight? How annoying! However, scientists are beginning to believe that some people get the ability to stay thin from their parents.
Scientists say that when some people eat, their bodies will naturally store the excess energy from food as fat. These people gain weight if they eat more than they need each day. Meanwhile, other people eat more than they need but their bodies are able to “burn off” the extra food without making fat, so they rarely have weight problems.
To show that this is true, scientists have experimented on laboratory mice. They gave the mice a special diet with a lot of fat. Some mice gained weight while the other mice stayed thin, even though both groups of mice ate the same amount of food and got the same amount of exercise. Scientists concluded that weight gain seemed to be influenced by genetic (基因的) factors. They also believe they have now identified the genes that may cause this tendency. These genes, according to the scientists, get passed down the generations. Armed with this knowledge, they believe it may be possible to develop medicines thatcan target the genes and stop people from gaining weight.
The study of weight gain is becoming more important as the numbers of people who are overweight continues to grow. In theUnited States, over seventy percent of the population have weight problems. This means they are at risk of illness such as high blood pressure and heart disease.
Current medicines for weight control do not work very well because they can have serious side effects, such as heart problems. However, it takes a long time to develop and thoroughly test new drugs. Therefore, despite this breakthrough in the study of weight-loss drugs, scientists and health professionals all agree that currently the best way to control weight gain is to have a healthy, balanced diet and an active lifestyle with daily exercise. This will not only help people avoid becoming overweight, but also help them stay healthy and energetic.
4. According to the scientists, some people ________.
A. are able to stay thin because of genetic factors
B. can eat what they want and stay healthy forever
C. usually keep doing exercise to lose their weight
D. don’t eat anything every day but still put on weight
5. Some people don’t need to worry about weight problems because ________.
A. they eat many vegetables
B. they eat less than others
C. they don’t store any energy from food as fat
D. they can burn off the extra food without making fat
6. What can we learn from the passage?
A. Fewer people will have weight problems in the future.
B. People with weight problems may suffer from heart trouble.
C. We now have good medicine for people with weight problems.
D. The result of the experiments on mice and humans are different.
7. What does the last paragraph imply?
A. Current medicine solve weight problems well.
B. We should exercise regularly and eat properly.
C. Taking exercise every day may cause heart problems.
D. Testing new drugs is hard because of the side effects.
C
Identifying the chemical makeup of pigment (色素) used in ancient documents, paintings, and watercolor1 s is criticalto restoring and conserving the precious artworks. However, despite numerous efforts, scientists had been unable to determine the source of folium, a popular blue dye used to color1 manuscripts (手稿) in Europe during the middle ages — from the 5th to the 15th century. Now, a team of researchers fromPortugalhas finally uncovered the mysterious ingredient responsible for the gorgeous blueish-purple color1 that helped bring ancient illustrations and texts to life.
The research team began byporing overinstructions penned by European dye makers from the 12th, 14th, and 15th centuries. They found what they were seeking in a 15th-century text entitledThe Book on How to Make All the Color Paints for Illuminating Books. However, translating the instructions was no easy task. It was written in the now extinct Judaeo-Portuguese language, and though the source of the dye was traced back to a plant, no name was mentioned.
However, by piecing together suggestions from the text, the scientists were able to determine that the dye was made from the bluish-green berries of the chrozophora tinctoria plant. After an extensive search, the team found a few varieties of the plant growing along the roadside near the town ofMonsarazin southPortugal.
The detailed instructions gave the researchers critical clues — including the best time to pick the berries. “You need to squeeze the fruits, being careful not to break the seeds, and then to put them on linen (亚麻).” The scientist says the detail was important since broken seeds polluted the pigment, producing an inferior quality ink.
The dyed linen, which was left to dry, was an efficient way to store and transport the pigment during ancient times. When needed, the artist would simply cut off a piece of the cloth and dip it with water to squeeze out the blue color1 .
Once the key ingredient had been identified, the researchers began to determine the dye’s molecular structure. To their surprise, they found that folium was not like any other known permanent blue dyes — it was an entirely new class of color1 , one they named chrozophoridin. “Chrozophoridin was used in ancient times to make a beautiful blue dye for painting.” the team wrote in the study. “Thus, we believe that this will not be our final word on this amazing plant and its story and that further discoveries will follow soon.”
8. The primary purpose of the study is to ________.
A. restore and conserve ancient precious artworks
B. determine the substance making up the folium
C. prove the ancient dye-making technique was organic
D. identify which class of color1 folium belongs to
9. The underlined phrase “poring over”in the second paragraph means ________.
A. discussing publicly
B. testing repeatedly
C. passing directly
D. reading carefully
10. What can be learned about the blue dye folium?
A. It was essentially an inferior type of ink.
B. It was the only kind made from wild berries.
C. It could be carried and used easily.
D. It was carefully squeezed from broken seeds.
11. The article is mainly about _________.
A. how the mystery ofa thousand-year-old blue dye was solved
B. why the researchers took the trouble to recreate the dye
C. what needs to be done to make an organic dye from a plant
D. when and where the discovery of the dye was made
D
If there is no difference in general intelligence between boys and girls, what can explain girls’ poor performance in science and math?
It hasbeen suggested that girls do not take math courses, not because they are difficult, but for social reasons.
Girls do not want to be in open competition with boys because they are afraid to appear less feminine (女性的) and attractive (有魅力的).
However, there are still more high-achieving boys than girls when taking math exams. This difference appears to be worldwide. Biological explanations have been offered for this, but there are other explanations too.
Perhaps the difference which comes out during the teenage years has its roots in much earlier experiences. From their first days in kindergarten, boys are encouraged to work on their own and to complete tasks. Facts show that outstanding mathematicians and scientists have not had teachers who gave answers.
Besides, there can be little doubt that teachers of math and science expect their boy students to do better at these subjects than their girl students. They even appear to encourage the difference between boys and girls. They spend more time with the boy students, giving them more time to answer questions and working harder to get correct answers from them. They are more likely to call on boys for answers and to allow them to take the lead in classroom discussion. They also praise boys more frequently. All of this seems to encourage boys to work harder in science and math and to give them confidence that they are able to succeed.
Such a way of teaching is not likely to encourage girls to take many math and science courses, nor is it likely to support girls who do. When it comes to these subjects it seems certain that school widens the difference between boys and girls.
12. Why does the author raise a question in paragraph 1?
A. To find differences between boys and girls.
B. To explain the poor performance of girls.
C. To ask readers a question.
D. To introduce the topic.
13. The text mainly discusses ________ reasons for the difference between boys and girls in scientific achievements.
A. biological
B. personal
C. social
D. historical
14. What does the text say about great mathematicians?
A. Their teachers did not offer answers to them.
B. They started learning math at an earlier age.
C. They showed mathematical abilities in their teenage years.
D. Their success resulted from their strong interest in math.
15. The author would probably agree that ________.
A. boys and girls learn in the same way
B. boys and girls are equal in general intelligence
C. girls are more confident in themselves than before
D. girls should take fewer science courses than boys
第二节（共5小题；每小题2分，满分10分）
阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

选项中有两项为多余选项How much time do you spend sitting every day?___16___Imagine sitting for nearly one-third of your life -to what degree would your health be affected? According to research, if one sits for long periods of time, the risk of diseases like obesity, diabetes and cancer will be greatly increased. A study in Australia even found that by reducing our sitting time to three hours a day, our lifespan(寿命) could be lengthened by two years!___17___ Now ask yourself, “Where do I normally spend long periods of time sitting?”___18___So what can we do to change that? One solution is that our classroom furniture could be changed to allow ourselves more standing time. It might seem absurd, but standing to learn is definitely an idea worth achieving.
To put this idea into practice, we have come up with a new idea-the Two-in-one sitting-standing- desk. How does this new invention work? First, the desk has extendable(可延长)legs so that the height of the desktop can be adjusted according to students' needs.___19___That means students can easily switch between sitting and standing positions. Second, there are two swing bars at the bottom of the desk which allow students to exercise their legs when they feel restless.
Some people might worry that if students are allowed to stand in class, they will be easily distracted(分心) and move around. Yet research shows the opposite to be true. People tend to be more focused if they are allowed to work standing up.___20___It is for this reason that a pair of swing bars have been fixed to turn those restless moments into beneficial exercise without interrupting schoolwork.
If sitting is the new smoking, the Two-in-one standing desk is the way to go for a healthier and more effective classroom.
A. So it's not real hard to explain.
B. It also comes with a high chair.
C. Without doubt, that is at school.
D. Obviously standing is better than sitting.
E. Probably seven to eight hours, or evenmore.
F. Sometimes you need strength of mind to stand up.
G. Of course, it is unfair to ask students to remain ly still for hours.
