【题目】Spam (垃圾邮件) mail is a fact of Internet life. Some of it carries bad things, but the main problem with spam is that it is unpleasant because it fills your mail box with pointless messages.
Most email programs have built-in filters (过滤器) that will discover unwanted messages and put them into a junk folder (垃圾文件夹). You can make the filter learn what you consider to be spam or block certain senders.
Avoid letting your email address appear on websites—spammers search the Internet for email addresses. Be careful who you give your email address to, and if you need to send out several copies of an email, use blind copy instead to cover the other people’s addresses.
Delete (删除) spam emails without opening them. Signs of possible spam are bad spelling in email headers, strange sender addresses, or emails sent at unusual hours. If you do open a spam mail, never reply to it or click on any pictures it may have.
If you receive an unexpected email pretending (伪装) to come from your bank, credit card company or other suppliers, be very careful. If the email asks you to reply, don’t do it! Instead, call up these places or visit their websites.
Consider setting up a second email address and keep one address for your personal use and another for your online communication.

【题目】Do you find it hard to learn math and history? A recent study carried out by scientists from University of London, may be of help to you. They found that teenagers could get higher marks in math if they studied in the morning and better grades in history if they were taught in the afternoon.
The researchers did a study at a secondary school in Bulgaria over nine years. The results showed that when teenagers had math classes earlier in the day, they scored on average (平均) 7 percent higher in tests than when taught in the afternoon. Lower-ability students did worst when they were studying math in the afternoon.
In history, students taught in the afternoon scored on average 6 percent higher than when they were taught in the morning. However, it doesn’t work for other subjects such as languages or geography.
Velichka Dimitrova, leader of the study, said the findings show that we do better at different times of the day.
“In the morning, our brains are better and fresher, so we are better at doing something that repeats a lot like problem solving, where we require more speed and attention,” Dimitrova told The Telegraph.
“In the afternoon, it seems that this process (过程) slows down. On the other hand, history is better suitable for the afternoon, when we are more creative and open to discussion,” she said.
Subjects such as foreign languages require both memory and repetition (重复), and they also need people to be creative. This is perhaps why the time of day has no influence on learning.
Time-of-day effects such as those are believed to be connected to the body clock. This is the system in our bodies that controls when we need to sleep. Some schools in the US and UK have tried out later school starting times for teenagers, whose body clocks change as they grow into adults.
Dimitrova believes schools should take this chance to improve students’ performance just by changing their timetables.
【1】History is better suitable for the afternoon because ______.
A. it is an easy subject for students to learn
B. we are more creative and open to discussion
C. our brains are better and fresher in the afternoon
D. it’s easier to pay more attention to the work we are doing
【2】It is believed that the time-of-day effects have something to do with a student’s ______.
A. age B. hobby C. body clock D. learning habit
【3】Dimitrova is sure that ______.
A. it is better to learn history and math in the morning
B. changing timetables properly can improve students’ performance
C. different times of a day have some influence on learning languages
D. it makes no difference for lower-ability students to learn math in the afternoon
【4】What is the main idea of the passage?
A. The good advice on managing a school.
B. The importance of learning history and math.
C. The good ways to get higher scores in history and math.
D. The influence of timetables on history and math learning.

【题目】Where did that number come from?
Eleven and Twelve
The reason behind the change in number naming is that eleven comes from the German term ainlif, which translates to “one left”. Twelve follows the same rule. It comes from twalif—“two left”. Why teen is used instead of lif for 13 through 19? There is something sadly lost in history.
911 for US Emergency (急救) Calls
Early phones didn’t use phone numbers—the operator had to connect your call by hand—and this led to the need for an emergency code (信号). But later phone numbers became popular, that changed. In 1967, 911 was chosen as the nationwide emergency call because it was easy to remember and could be quickly dialed (拨) on the phone.
26.2 Miles in a Marathon (马拉松)
The story began with an ancient Greek soldier carrying message from a battlefield (战场) in Marathon to Athens. The modern marathon was born as a flagship event in the first Olympic Games, in 1896, with a distance (距离) of about 25 miles (40 km), as long as the distance from Marathon to Athens. But race organizers for the 1908 Olympic Games in London wanted to add something special. The race began at Windsor Castle and ended at White City Stadium, with runners finishing only after passing the royal (皇室的) box. The distance was 26.2 miles (42.1 km). And since 1924 this distance has been kept in marathon.
28 Days in February
Before using the Gregorian calendar that we use today, one of the first Roman calendars had only 304 days and span>ten months (March through December), with six months of 30 days and four of 31 days. The second king of Rome improved the old calendar. He added 50 days for January and February. To make the new months longer, he took one day from each of the 30-day months, making 56 days to divide between January and February (or 28 days each). Later January was given one more day to add up to 355 days a year, but February still had 28 days. That’s how it became the shortest month and it stayed that way ever since.
【1】Which language do eleven and twelve come from?
A. English. B. German. C. French. D. Russian.
【2】When was the number 911 chosen for US emergency calls?
A. In 1896. B. In 1908. C. In 1924. D. In 1967.
【3】 The marathon distance was made longer at London Olympic Games because ______.
A. the British was a little weak in maths
B. the British didn’t like the Greek story
C. the British loved the royal family very much
D. the British wanted to make the race different
【4】 How many days were there in each month after the king improved the old calendar?
A. 28, 29 or 31. B. 28, 30 or 31.
C. 28, 29 or 30. D. 29, 30 or 31.

【题目】It was once thought that only time could mend a broken heart, but now scientists think taking a couple of aspirin might be the best way to get over a break-up.
Previous studies have shown that people experience feelings of romantic rejection (失恋) in the same way that they experience physical pain. And Psychology Professor Water Michel, of Columbia University, also believes that the psychological pain of ending a relationship is similar to physical pain, and should be treated like any other injury. “When we speak about rejection experiences in terms of physical pain, it is not just a metaphor – the broken heart and emotional pain really do hurt in a physical way," he said. “When you look at a picture of the one who broke your heart, you experience a pain in a similar area of the brain which is activated when you burn your arm. ”
Research shows that people who are given a simple painkiller, like aspirin, are able to handle feelings of rejection better than those given a placebo (安慰剂) .
‘Take two aspirins and call me next morning’ would be a cold-hearted response to a friend’s late-night report of fresh heartbreak, but it has a solid basis in the research.
【1】The aspirin is a kind of _________.
A. wine B. fruit C. dessert D. medicine
【2】According to the passage, maybe taking aspirins can ______.
A. mend a broken heart B. burn your arm
C. make people feel pain D. help people get over a break-up.
【3】The underlined word “those” in Paragraph 3 means ______.
A. pains B. hearts C. people D. areas
【4】The best summary for the passage would be “Broken-hearted? _______________ !”.
A. Just take an aspirin or two
B. Just call me at any time
C. Just wait for a long time
D. Just eat as much as you can
