【題目】閱讀理解
A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep. But now a study has found it really does help people nod off---if it is milked from a cow at night.
Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.
The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.
Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.
Night milk quickened the start of sleep and caused the mice to sleep longer.
While the effect of cow's milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.
Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.
Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.
(1)According to the text, the mice fed with daytime milk _________.
A.started sleep more easily
B.were more anxious
C.were less active
D.woke up later
(2)Which of the following is true of melatonin according to the text?
A.It's been tested on mice for ten times.
B.It can make people more energetic.
C.It exists in milk in great amount.
D.It's used in sleeping drugs.
(3)What can be a suitable title for the text?
A.Night Milk and Sleep
B.Fat, Sugar and Health
C.An Experiment on Mice
D.Milk Drinking and Health
(4)How does the author support the theme of the text?

B.By stating arguments.
C.By explaining statistical data.
D.By providing research results.

【解析】本文是一篇說(shuō)明文,介紹了晚上喝牛奶和睡眠的關(guān)系。牛奶包含更多的褪黑激素,這種物質(zhì)可以幫助睡眠。

(4)考查細(xì)節(jié)理解。根據(jù)第一段中的“But now a study has found it really does help people nod off—if it is milked from a cow at night.”一項(xiàng)研究表明……;第二段中的“Researchers have discovered that ‘night milk’contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.”研究者已經(jīng)發(fā)現(xiàn)晚上牛奶包含更多的褪黑激素,……;UI及第三段中的“ The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night. ”來(lái)自漢城的研究者……?芍髡呤峭ㄟ^(guò)提供研究結(jié)果來(lái)支持文章主題的。故選D。

Rodney Smith, Jr. started mowing the lawns (割草坪) in Huntsville, Alabama last fall. He used his time between classes at Alabama A&M to reach a goal of mowing 100 yards before winter. Smith has been cutting grass for free to help single moms, the elderly, and the disabled, while teaching the local youth the values that can turn boys into men. “I'm doing something positive. I want boys to follow me and be better than me,” he wrote on his Facebook page.
Rodney is from Bermuda. He says people there help each other and are always friendly. “That's what drives me to help people.”
In May this year, he was getting ready to launch his mowing service for the summer when he heard about a 93-year-old woman trying to cut grass by herself. Smith and a friend showed up to do the job for her.
In November, a local TV station gave him $300, calling it a special gift for his good work. After he received the money, he used it to create the non-profit(非盈利的) service group, Raising Men Lawn Care Service. He also started a page to collect money to buy lawn equipment and other things—including T-shirts with special logos.
After I read about Rodney's story, I told my friends about him. We also planned to mow lawns for single moms, the elderly and disabled in our neighborhood. And I hope more and more young people will join Rodney's service group—Raising Men Lawn Care Service.

【題目】根據(jù)短文內(nèi)容,選擇最佳答案。
Our children and grandchildren may not have a chance to visit many of the most famous places around the world. War, weather, age, traffic and pollution damage these famous places. Looking after these places often costs more than one country can afford.
In the early 1970s, world governments decided that if they joined together, they would be able to preserve our history. If every country paid some money, they said, it would be possible to look after important historic places. Also, if they discovered that a monument needed urgent help, they would have money for repairs. For these reasons, countries around the world united to form the World Heritage Organization in 1972. Today, the organization helps to maintain and restore the most important places from our history.
However, one of the biggest problems for historic places is vandalism. People sometimes enter the sites and destroy or damage the buildings. At some sites, such as Stonehenge(巨石陣)in England, governments have built high fences to protect the site from vandals.
There are many different ideas about how to solve the problem of vandalism. Stone experts say that if guards patrolled the sites, vandals would not be able to get in. Some experts say that if they fixed more television cameras, they would not need so many guards. Other experts say that the best solution is education. If people learned to respect history, they would not destroy or damage it. They would also want to spend money looking after old places. For this reason, the World Heritage Organization helps to spread information about the value of historic sites.
(1)Why did countries all over the world unite to form the World Heritage Organization?
A.It would be able to keep our history.
B.It would be possible to take care of important historic places.
C.They would have money to do some repairs if a monument needed help.
D.All of the above.
(2)Which of the following shows us the action of vandalism?
A.People enter the sites and cause damage to the buildings
B.Governments build high fences to protect the site from vandals
C.Guards patrolled the sites and they fixed more television cameras
D.They collect as much money as they can to preserve the buildings
(3)What's the best way to solve the biggest problem of preserving our history?
A.Every country spends more money looking after these places
B.To form the World Heritage Organization
C.Too many guards are needed to prevent vandals getting in
D.To make people know more about the value of historic sites

【題目】With the summer holiday just around the corner, it seems like everybody is busy planning their vacations. Here are some tips that can help you enjoy your holiday without emptying your pocket:

Travel off-season

Go to your desired destination while the demand is low and take advantage of huge discounts. During the peak season, the hotel and flight prices increase quickly, and you’ll likely spend more of your vacation time standing in line due to the rush of tourists.1

2

Websites can help you find discount hotel rooms. Look for places that do not charge extra for children if they use the existing bedding. Stay with the locals. If you and your family are going to stay for a longer period, renting a small apartment is a good choice.

Eat like a local

Why eat at big chain restaurants when you can experience something new?3During your family trip, try new food where the locals eat. This will not just save money, but also provide you with a new and different experience. For smaller meals and snacks, avoid restaurants and try street food or other takeout.

Don’t hesitate to bargain

Tourist- heavy places are known for overcharging for just about everything. Clothes, travel goodies, souvenirs, etc. are very expensive at these places.4Bargain hard to get the best price.

Choose local transportation

5Instead, take buses, railways or subways, which are always cheaper. If you are planning to stay for a while, you can consider renting a car. Hiring a car is much easier than carrying your bags everywhere if you are moving around a lot.

A. Save on hotels.

B. Surf the Internet while traveling.

C. Therefore, avoid buying anything there.

D. So it’s best to find out when the off-season starts.

E. Planning your meals is another way to reduce your travel costs.

F. For this reason, you shouldn’t feel ashamed to ask for bargains.

G .As a tourist, avoid taking taxis whenever possible, since they are expensive.
