The warm colours are red, orange and yellow. Where there are warm colours and a lot of light, people usually want to be active. People think that red example is exciting sociable (善交际的) people, those who like to be with others like red. The cool colours are green, blue and purple. These colours unlike warm colours, are relaxing. Where there are cool colours, people are usually quiet. People who like to spend time alone often prefer blue.
Red may be exciting but one scientist says that time seems to pass more slow in a room with warm colours than in a room with cool colours. He suggested that a warm colour such as red or orange, is a good colour for a living room or a restaurant.
People who are relaxing or eating don’t want time to pass quickly. Cool colours are better for offices of factories as the people who work there want time to pass quickly. Scientist don’t know why people think some colours are warm and other colours are cool.
However, almost everyone agree that warm colours remind (使想起) people of warm days and cool colours remind them of cool days. Because in the north the sun is low during winter, the sunlight appears quite blue. Because the sun higher during summer, the hot summer sunlight appears yellow.

【推荐1】Theme Numbers
Most kids learn how to count on their fingers (手指). However, many people think finger-counting looks a little silly. As kids grow older, their teachers often tell them not to count using their fingers.
But these teachers may be wrong. Scientists now believe it is a great idea for children to count using their fingers. The habit is good for their math study. It’s not hard to see why. By using fingers, an abstract (抽象的) idea becomes easy to understand. Kids then find it easier to work out difficult math problems.
In fact, there is an area (区域) in our brain (大脑) called the “finger area”. In 2015, a group of US scientists made a study about the area. They found the “finger area” became active when students worked on math problems. This is true even when the students don’t use their fingers. If students are good at finger-counting in the first grade, they will be better at math in the second grade. The ability to count by using fingers can decide students’ future grades in math tests. Other studies also showed the finger use is good for math ability (能力). For example, some scientists find pianists (钢琴家) are often good at math.
Unluckily, school teachers don’t think the finger use is important. Few of them ask students to count on their fingers. Maybe it is time for people to have a new understanding of finger-counting. Teachers should help students of any age develop (开发) their “finger area” by using fingers.
1. Why do teachers tell older kids not to count on their fingers?| A．It is too easy. | B．It looks a silly thing. |
| C．It is not good for their brain. | D．It is not helpful for their math study. |
| A．The finger use can’t help with math study. |
| B．Some pianists are good at music and sports. |
| C．The finger area is always active when students study. |
| D．Finger-counting helps students get good grades in math tests. |

【推荐2】Some things just don’t get along well with each other. Take oil and water as an example. You can mix them together and shake as hard as you like but they’ll never become friends...or will they?
What you’ll need:
◆A small soft drink bottle ◆Water ◆Food coloring
◆Two tablespoons of cooking oil ◆Dish washing liquid or detergent（洗涤剂）
Instructions:
Add a few drops of food coloring to the water.
Pour about two tablespoons of the colored water along with the two tablespoons of cooking oil into the small soft drink bottle.
Shake the bottle as hard as you can.
Put the bottle back down and have a look. It may have seemed the liquids were mixing together but the oil will float back to the top after a while.
Add some dish washing liquid or detergent. Detergent is attracted to both water and oil, helping them all join together and form something called an emulsion（乳状液）. This is good to use when washing those greasy（油腻的）dishes. The detergent takes the oil and dirty things off the plates and into the water, yeah!
根据短文内容，判断下列句子的正（A）或误（B），并在答题卡的相应位置将其涂黑。
1. In this experiment（实验）, you need two tablespoons of food coloring.
2. Pour colored water and cooking oil into a soft drink bottle.
3. Dish washing liquid is the key of this experiment.
4. Oil and water cannot be mixed together all the time.
5. You may find this passage in a science book for kids.
【推荐3】When is a dollar worth much more than a dollar? When can a mistake make something worth much more? What gets more valuable with age? Numismatic experts love to discuss these questions!
When most people consider the value of paper money, they take a quick look at the face value. (The face value is the value printed on the money itself.) A numismatic expert takes a much closer look!
Becoming a numismatic expert requires attention to details. There are many words, pictures and numbers on each dollar bill. One thing a numismatic expert will consider when looking at paper money is the type of currency (货币). At the top of most U.S. dollars, you will see the words Federal Reserve Note. On a very small number of bills, you may see the words Silver Certificate. Before 1968, a Silver Certificate could be changed for silver. So don’t spend that bill because it is probably worth more than a dollar.
Next, a numismatic expert is likely to take a look at the serial numbers on the bill. The serial number is printed both on the bottom left and on the upper right of most U.S. dollars. If the serial numbers do not match, the dollar bill is worth much more than a dollar. Bills with certain serial numbers are also likely to be worth more than their face value. For example, a bill with a repeating serial number, such as 5555555 is in high demand. This makes it worth much more than a dollar. A bill with an asterisk (*) before the serial number notes that there was an error before production of the bill. This asterisk often makes the bill more valuable.
If any of the numbers or pictures on a dollar bill are shifted, not printed exactly where they should be, the value of the bill increases greatly, which makes it have a very high collection value. There is much more to learn about numismatics. If you would like to become a numismatic expert, the first step is to take a closer look at the money that passes through your hands. Good luck!
