Babies who watch TV are more likely to show late learning development and language at 14 months, especially if they are watching programs aimed at adults and older children, according to a new study, which would probably surprise those parents who leave their babies in front of a TV set.
Babies who watched 60 minutes of TV daily had developmental scores a third lower at 14 months than babies who were watching less TV. Although their developmental scores were still in the normal range, the difference may have been due to the fact that when children and parents are watching TV, they are missing the talking, playing and other communications that are important to learning and development.
This new study, which appeared in the Aechives of Pediatric and Adolescent Medicine, followed 259 lower-income families in New York, most of whom spoke Spanish as their primary language at home. Other studies of higher-income families have also come to the same conclusion: TV watching is not only non-educational, but it seems to slow down babies’ development.
But what about “good” TV, like Sesame Street? The researchers didn’t find any difference when compared to non-educational programs designed for small children, like Spongebob SquarePants. Earlier research by some of the same scientists, most of whom are at New York University School of Medicine’s Bellevue Hospital Centre, has found that parents whose children watch non-educational TV programs like Spongebob SquarePants spend less time reading to their children or teaching them.
At this point, parents reading this will probably be astonished. TV is so often a parent’s good friend, keeping children happily occupied（占时间）so that the adults can cook dinner, answer the phone, or take a shower. But, clearly, this electronic babysitter（保姆）is not an educational aid. It is best to make sure the babies are fast asleep if you have to watch TV.According to the first paragraph, 14-month-old babies who watch TV probably_______.

| D．Lower-income families tend to teach their babies at home |

Carrot juice, because of its many healthy benefits, is commonly called the "magic juice". It has been found that adding carrot juice to people’s diets greatly improves their health. And its delicious taste makes it popular with all members of the family as a beverage.
Carrot juice is one of the richest sources of vitamin A that can be used in the daily diet. Lack of vitamin A can cause dryness and damage to the skin, nails and hair. Drinking carrot juice to increase the vitamin A in the diet is said to be good for many parts of the body, including the bones and teeth.
Drinking carrot juice is thought to be extremely helpful to the liver (肝脏), because vitamin A helps to clean the liver and reduce fat in it. And it is suggested that drinking carrot juice should be done regularly, rather than just from time to time.
Drinking carrot juice is also thought to improve the eyesight because of the vitamin A in the juice. Lack of vitamin A can lead to night blindness, which can be very dangerous, especially when the person is driving a car. An easy way to find out if you are lacking in vitamin A is to walk from a bright room into a dark room. Your eyes may have some trouble in getting used to the change of light if you are lacking in vitamin A.
How can you make carrot juice? Wash some carrots well in cold water. Scrape (刮) them lightly, but do not peel them, as this will take away valuable vitamins and minerals that lie close to the skin. Lack of vitamin A can lead to _____.

UFO stands for "unidentified flying object"(不明飞行物). Many people reported having seen UFOs in the sky. A lot of countries tried to research into them and in 1952 they got the name of UFO.
There were several reports published in the 19th century which were related to UFOs. Denison Daily News in its report of 25th January, 1878 wrote that a farmer, Martin saw a flying object in the sky and it was just like a plate. This was the first time that the word plate had been related to the UFO.
First reports on UFOs came during the World War II. In 1947 the pilot Kenneth Arnold said while he was flying near the Mount Rainer he saw a very bright object in the sky. He told that it was like a plate, too. The information given by Kenneth got lots of attention from the media and people.
Several research organisations gave their reports on the UFOs. They showed direct or indirect physical evidence of UFOs, and sometimes UFOs’ appearance was found in the radar (雷达) screen. Many people try to take video tapes or photos of UFOs as proof. Most UFOs are in plate shape while many UFOs are like cigarettes or half balls.
Many films and TV shows are made about UFOs. There are two famous movies which are created on the topic of UFOs and aliens (外星人), War of the World and Star Wars. UFOs have created a new field in science which is known as Ufology (飞碟学).Which of the following is TRUE according to the passage?

I told my friend Graham, "I often walk two miles from my house to the town centre. Unfortunately, there is a big hill on the way." He replied, "You should say 'fortunately’." He explained that I should be glad for the extra exercise that the hill gave.
I thought he was right. My attitude to the hill has now changed. As I approach the foot of the hill and prepare to climb, I tell myself that this hill will help me lose weight and get fit. This hill is my friend. I have a smile of satisfaction as I reach the top of the hill.

London’s Chinese community dates back to the 18th century, when a small number of Chinese sailors moved to the city to work in Limehouse, east London. As time went by, other Chinese people came to this area and Limehouse began to be known as "Chinatown". At the start of the 20th century, there were just 545 Chinese people in Britain. However, this situation changed greatly after the Second World War. At this time, many farmers in Hong Kong lost their jobs, and decided to move to London. In the 1950s, a small Chinese restaurant opened in central London. Many British people visited it and said that Chinese food was wonderful! Suddenly, Chinese restaurants started opening in every part of the city. Instead of too little work, the new Chinese immigrants (移民) now found that they had too much! Most of the new immigrants enjoyed their lives and the chances they were offered. Many asked their friends and relatives to join them from their hometowns, and a lot of families were reunited again at this time.
As time went by, London’s Chinese community became more and more successful. The sons and daughters of the first restaurant workers, encouraged by their parents, studied very hard at school and university. And most got highly-paid jobs. As a result, increasing numbers of Chinese families left Chinatown and moved to the more expensive places. Chinatown, however, is still as lively as ever, and a must-see for any visitor to London.From the passage, we can learn that the first members of "Chinatown" were _____.

When we donate（捐献） blood, a small amount is usually taken in advance for at least ABO and Rh systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh + or Rh-.
The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances(物质) contained in each type, the four groups must be transfused carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital.
There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The least common is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world.Which of the following shown the correct relationships in blood transfusions?

| A．to put the blood into a container |

| D．to give power to another person |
The writer suggests that the third most common blood type among the Europeans is ______.
