When you work long hours and Sundays are no longer a day to rest, feeling overworked can become the new normal. Take sportsmen as examples and do the same yourself, so you’ll know if you’re overworking.
Check your resting heart rate (率). Every day, before you get out of bed, take your pulse (脈搏). Usually your heart rate will stay within a few beats every minute. But when you’re overworked, the rate increases. If your heart rate is up in the morning, get a little more rest or sleep that night.
Check your emotions. Getting angry easily? If you can’t put your finger on a clear reason, there may be something wrong with your emotions. Hoping to change the condition won’t help. The only way out is a break.
Check your weight. If you lose or increase more than 1% of body weight from one day to the next, something is wrong. Maybe yesterday you were too busy and failed to notice you didn’t eat and drink enough. Or maybe you failed to notice that you were eating too much.
小題1:How many ways are mentioned to check if we’re overworking?
A.Two.B.Three.
C.Four.D.Five.
小題2:When should we check our heart rate?
A.In the morning.B.In the afternoon.
C.At noon.D.At night.
小題3:What is the best way to deal with the problem of overwork?
A.Doing more sports.B.Drinking more water.
C.Having more rest.D.Eating less food.

Bikes are popular in the Dutch(荷蘭). In fact, nearly half of all travel in the Dutch is by bike. Now, one Dutch bike designer(設(shè)計(jì)師), Thomas, has taken the country’s interest in bikes by making a school bus bike.
The big bike has eight sets of pedals(踏板) for kids, a driver seat for an adult, and three other seats, comfortably letting little kids for their trip to and from school. The bike even has a motor, which can help with high hills or at times when few kids on it.
So far, Thomas tells Fast Company, he’s sold 25 school-bikes, at a price of $ 25,000 each—less than it would cost to buy a traditional school bus with the same number of seats. Along with the traditional color, the bikes ,are colored yellow so that they can be seen easily.
Thomas says he’s sold school bus bikes to neighboring countries such as Belgium, England and Germany, but so far, the school bus bike hasn’t been sold in the United States. If the U.S. agrees to buy this kind of school bus bike, it could do a lot of good to improve exercise for a young age and help them keep healthy.

小題1:How do people in the Dutch usually go to work?
A.By car.B.By bus.
C.By bike.D.On foot.
小題2:How many seats does the school bus bike have?
A.Three.B.Eight.
C.Nine.D.Twelve.
小題3:The school buses are yellow in the Dutch because _______.

C.yellow is the national color of Dutch
D.it’s the designer’s favorite color
小題4:Which country of the following hasn’t bought a school bus bike?

What will the car be like in the future? Maybe we can sit in a car that can drive itself.
About 40 years ago, scientists from the United States started to develop self-driving cars (無人駕駛汽車). The most famous recent one was made by Google in 2009. There are cameras and radars (雷達(dá)) on the top of the car. They allow the computer in the car to draw a 3D map of the environment. Chinese scientists have also successfully developed a self-driving car. The car made a trip from Changsha to Wuhan.
Is a self-driving car safe? A recent study shows that robots make safer drivers than humans. If only 10% of cars on the street are self-driving, they will save 1,000 lives (生命) every year. If 90% of vehicles (交通工具) are self-driving, 21,700 lives will be saved a year. However, a self-driving car is expensive and each costs about $100,000. So it is impossible to be very popular in the near future.
根據(jù)短文內(nèi)容,判斷下列句子正誤。正確的用“A”表示,不正確的用“B”表示。
小題1:American scientists started to develop self-driving cars in 2009.
小題2:Cameras and computers are on the top of the self-driving car by Google.
小題3:In China, scientists have successfully developed a self-driving car.
小題4:The more self-driving cars there are on the street, the fewer traffic deaths there will be.
小題5:The self-driving cars will be very popular in the near future.

Can you imagine living in the desert for a whole year, watching the activities of a group of busy ants? Deborah Gordon did exactly that. She finally found out that there were four main groups of workers in the ant team: cleaners, haulers(搬運(yùn)工), gatherers and security (安全) ants. Each group did their own job to finish the task of the whole team.
Cleaner ants carried waste food from inside the nest to outside. Hauler ants walked on the top of the nest and cleared rubbish. Gatherer ants went out to find food for the whole team and security ants fought against anyone who wanted to hurt the members of the team.
While she was watching the ants in the desert, Deborah found that the most interesting part was watching the ants dealing with difficulties, such as fighting against other insects that wanted to destroy their nest, or a big fire. At those moments, they would all stop what they were doing and go to help security ants to protect their home.
What do we do when people around us meet difficulties? What have we done to turn our world into a better place? It’s time to think.

A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury (埋葬) it in the garden and wait for it to flower(開花). A biodegradable (生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage users to recycle. Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any poisonous(有毒的)chemicals. British researchers used the new material to develop a phone cover that includes a sunflower seed .When this new type of cover turns into waste, it forms nitrates (硝酸鹽). These feed the seed and help the flower grow. Engineers have designed a small transparent (透明的) window to hold the seed. They have made sure it only grows when the phone is thrown away. “We’ve only put sunflower seeds into the cover so far. But we are working with scientists to find out which flowers would perform best. Maybe we could put roses in next time.” said one scientist.
As phone technology is developing so quickly, people are constantly(不斷)throwing their mobiles away. This means producers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can change this, according to the scientists.
根據(jù)短文內(nèi)容,從題中所給的A、B、C、D四個(gè)選項(xiàng)中,選擇最佳答案。(10分)
小題1: After you have finished using the new type of mobile phone, _______.
A.the phone will do harm to the environment
B.the phone cover will break down easily in the soil you bury it
C.it will be recycled by the producers
D.it can be sent back to the shops.
小題2: Which of the following is wrong about the cover of the new type of phone?
A.It can help the sunflower seed after the mobile phone breaks down.
B.It looks like normal plastics but it can break down.
C.It includes a sunflower seed.
D.It makes sure the seed only grows after the phone is thrown away.
小題3:The new type of phone can reduce the harm to the environment mainly ______.
A.because of the material of its cover
B.because of the sunflower seed
C.because it’s made of no poisonous chemicals
D.because you bury it in the soil after you finish with it
小題4: This type of research is done because ________.
A.the technology that produces mobile phones is changing quickly
B.users are constantly throwing their mobiles away
C.nobody has ever thought of recycling mobile phones
D.producing mobile phones uses a lot of energy, so this has become a very big problem for the environment
小題5:We can guess from the story ________.
A.the new type of mobile phones is already on the market
B.the new type of mobile phones will sell very well

 Scientists have made the world’s first human-sheep----with the body of a sheep and half-human organs(器官). Amazing, but true. The sheep is15percent human and 85 percent sheep. The breakthrough(突破)makes it possible to use animal organs in human bodies in the future. Professor Esmail Zanjani of University of Nevada, US, has spent seven years And over $9 million on the work. Zanjani took stem cells(干細(xì)跑) from the human body and put them into the sheep while it was still in its mother’s body. The stem cells made other cells that grew into organs.

These organs could be used to help people in need of them. There are different opinions about his work, however. Some say that scientists don’t have the right to create new creature(生物).
