【推荐1】It might be fun to use your smartphone, but be careful. Too much screen time may be harmful to your health.

First, it is bad for your eyes. A researcher called Sarah Hinkley says the problem comes from the blue light that the screen gives out. Looking at a smartphone for a long time can cause eye strain(劳损), headaches and dry eyes. So it is a good idea to take a break every 15 minutes when you are working at a computer or using a smartphone.

Second, screen use can do harm to children’s brains. A new study shows that using screens too much can affect(影响) how children’s brains grow. If children use screens for more than one hour a day, they might have lower levels of white matter in their brains. White matter is a key to the development of language and reading skills. So it is wise to cut down the time of children using all kinds of screens.

Third, using screens too much will affect your sleep. According to a study, about 95% of the people between the ages of 13 and 64 use electronics before bed, especially the young people under 20. Doctors say that the light from those electronics at night may make you excited before you go to bed. Then it’s hard for you to get enough sleep. So you’d better turn off smartphones, TVs, and all other screens an hour before your bedtime.

To keep healthy, doctors and researchers strongly advise that you shouldn’t use screens for long hours.

【推荐1】The father’s role in the family is important. One researcher says babies who are cared for by their fathers have greater cognitive（认知的）development at one year of age than babies not cared for by their fathers. Another researcher reports that by spending time with their pre-school children, fathers can help to develop children’s language ability. Researchers also point out that for school-age children, fathers are one bridge with the outside world.

Fathers who value（重视）education have children who do better in school than those children whose fathers don’t value education. What’s more, fathers who spend quality time with their children may give their children happy memories which may last a lifetime. While each father is a unique person who educates children in his own style, good fathers have something in common.

Good fathers attend their children’s school activities. They also involve the children in their lives and the adult world by taking them to see the workplace, or by taking them when the car needs to be repaired, etc.

Good fathers expect a great deal from their children, but also accept and support the unique individuals（个体）that their children are becoming.

Good fathers prefer explanations and reasoning to force.

Good fathers know their time with children is really an investment in them.

Being an involved father is good for children and good for fathers. Both children and fathers have the chance for growth and development. Today’s lifestyles are changing. More and more fathers are keeping a balance between their personal life, work, and family time.

【推荐3】How do you feel about nature? After spending hours indoors, do you feel better when you visit your local parks? Most people think that nature is good for our bodies and brains (大脑). However, the number of visitors to Canada’s national parks is getting lower every year. And in countries such as the USA, only 10% of teenagers spend time outside every day. Many doctors feel that this is a problem in the twenty-first century.

As a result, some doctors are studying the connection (联系) between nature and health: one example of this is the work of Dr. Matilda in Sweden. The doctor gave people a math test. During the test, their heart rates (心率) were fast. After the test, one group of people sat in a 3D-virtual-reality (虚拟现实) room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than those people’s in the other group.

The virtual touch with nature helped them feel more relaxed. The natural world allows our brains to rest and slow down, and can trigger positive (积极的) feelings and a sense of peace. Another good example of how nature is good for health comes from Canada. In Toronto, researchers studied 31,000 people living in the city. They found that healthier people lived near parks.

Because of studies like these, some countries and cities want nature to be part of people’s everyday life. In Dubai, for example, there are plans for a new shopping mall with a large garden so shoppers can relax outside with trees, plants and water. In Switzerland, “forest schools” are popular. School children study their subjects in the forests and do lots of exercise outside. And Republic of Korea is another good example. It has new forests near its cities and around 13 million people visit these forests every year. So after building cities for so long, maybe it’s now time to start rebuilding nature.

A．Teenagers’ learning in the 21st century.

B．Visiting local parks.

C．How much time we spend outdoors.

D．The tourism in different countries.

2. After the math test, the heart rates of people who sat in a 3D-virtual-reality room were ________ the heart rates of those who didn’t.

【推荐2】What can drones do? Their many uses include taking pictures from the sky, watching wild animals and sending packages of goods. Now these small flying robots are leading a big change in farming.

With cameras and some data-collecting devices, drones provide us with an eye in the sky. Here are a few of the farming jobs drones can do.

Looking for sick crops

Drones can scan crops using different kinds of light. In this way, they carefully examine the fields and produce detailed pictures that can help us find sickly yellow plants within fields of green. Drones can also check for bacteria that are harmful to crops in the air from a few kilometers away, so that farmers can try to find ways to protect their crops before the bacteria get to them.

Water watch

Most fields aren’t perfectly flat. There might be hills, slopes and holes. After watering, some places may dry out faster. Some spots might not get water at all. Drones can scan the field and make a 3D map. Using the map, farmers can find out which parts of a field are dry or need improvement. This can make sure every crop can get enough water to stay healthy.

Spraying pesticide(喷洒农药)

Different parts of a field might have different heights. Drones can check for this when flying above the land. Then, they change their height and therefore spray the correct amount of pesticide over each part of the field. This way works much better than traditional pesticide spraying. Drones can finish spraying a field up to five times faster than with traditional machinery, according to a study. This can stop insects from damaging the crops in a shorter time.

1. How many farming jobs done by drones are introduced in the passage?

A．3

B．4

C．5

D．6

2. Which of the following use of drones is NOT mentioned in the passage?

A．

B．

C．

D．

3. What advantage of drones is mainly discussed in this passage?

A．Drones can make farmers’ lives easier.	B．Drones can have a clearer look of fields.

【推荐3】The Lantern Festival falls on the 15th of the first month of the lunar calendar. This day is always the first full moon in the New Year. Ancient people also called it Shangyuan Festival. Celebrations and traditions on this day began from the Han Dynasty and became popular in the Tang Dynasty.

Watching the red lanterns is one of the main traditions. Lanterns of different shapes and sizes are usually put on trees, or along river banks on show. It is said that sky lanterns were first used by Zhuge Kongming to ask for help when he was in trouble. Today, when the lanterns slowly rise into the air, people make wishes.

Another tradition is guessing lantern riddles. The riddles are usually short, wise, and sometimes humorous. The answer to a riddle can be a Chinese character(汉字), a famous person’s name, or a place name.

The most important thing is to eat sweet dumplings with different tastes. In northern China, they are called yuanxiao while in southern part they’re named tangyuan. Because making sweet dumplings is like a game or an activity, they are usually done happily by a group of friends or family members.

In old times, the Lantern Festival was also romantic(浪漫的). Watching lanterns gave young people a chance to meet each other. A line from Xin Qiji, a poet during the Song Dynasty shows this:

Hundreds and thousands of times I searched for her in the crowd. Suddenly I turned, and there she stood, in the dim(昏暗的) light.
