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 cows 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 years

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?

A. By giving examples.

B. By stating arguments.

C. By explaining statistical data.

D. By providing research results.

Section C

Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.

Walking will be banned on escalators as part of a trail designed to reduce congestion(拥堵) at some of the country’s busiest stations.

In the first move of its kind, all travelers will be forced to stand on both sides of escalators on the London Underground as part of a plan to increase capacity(容量) at the height of the rush hour.

A six-month trial will be introduced at Holborn station from mid-April, eliminating the rule of standing on the right and walking on the left. The move, imitating a similar structure in Far eastern cities such as Hong Kong, is designed to increase the number of people using long escalators at the busiest times . It could be expanded across the Tube network in coming years.

According to London Underground, only 40 percent of travelers walk the full length of long escalators, leaving the majority at the bottom as they wait to get on to the ＂standing ＂side.

A three-week trial at Holborn last year found that the number of people using escalators at any time of could be raised by almost a third. Peter McNaught, operations director at London Underground, said: ＂It may not seem right that you can go quicker by standing still, but our experiments at Holborn have proved that it can be true. This new six-month trial will help us find out if we can influence customers to stand on both sides in the long term.＂

Holborn has one of the longest sets of escalators on the Underground network at 23.4 high. Tube bosses claim that capacity was limited because so few people wanted to walk up—meaning only one side was used at all times. Research has shown that it is more effective use of escalators over 18.5 to ban walking.

The previous trial found that escalators at the station normally carried 2,500 people between 8:30am and 9:30am on a typical day, rising to 3,250 during the researching period.

In the new trial, which will be launched from April 18, one of three ＂up＂ escalators will be standing only, with a second banning walking at peak times. A third will remain a mix of walking and standing.

(Note: Answering the questions or complete the statements in NO MORE THAN TEN WORDS.)

1. What is the existing problem with standing on the right and walking on the left?

2. What did last year’s three-week trial at Holborn station prove?

3.The research suggests that walking should be forbidden on escalators that are at least _________ in height.

4. In the new trail, in addition to one escalator banning walking in rush hours, the other ＂up＂ escalators will be used for_________________.

Some people go through life positively. 1. Luckily, you can learn to become positive. If you become more positive, things will become brighter day by day. It’s not because things are any better, but because how you look at them will change. Here are a few things positive people do differently.

They find something to look forward to every day. Whether it’s catching up on a favorite TV show, trying out a new dessert recipe, or having a phone conversation with a friend in another town, these things don’t have to be big. 2. .

3. Joy isn’t so hard to find. You can even find joy in the tiniest things — a funny text from a friend or a beautiful sunny day — because it adds up. Soon, you won’t have to stop and smell the roses because you’ll be smelling them all the time. So learn to enjoy the small things in your life.

They stay busy. Being busy doesn’t mean living under much stress. 4. It means having something to look forward to every day. Start a hobby. Fill your weekends with your hobby. Remember, living your life to the fullest is up to you.

5. When in doubt, choose kindness. Positive people look on the bright side, sure, but they also tend to pay it forward by passing on their positive energy to others. Giving is generous, but it also makes the giver feel even better. Now that’s a win-win. Be kind to others and others will treat you in the same way. And your days will be much better.

A. It means filling your life with good activities.

B. They celebrate small things.

C. They are kind.

D. They do something for fun.

E. Kindness is most important.

F. Having activities to expect will make you happy every day.

G. But not all of us were born to be positive.
