Question: Read the article and select the best answer. Article: In Wiltshire, England, volunteers are being sought to visit a nature protection area to count the butterflies living there and on surrounding fields. The project is promoted by an environmental protection organisation,which has contributed to improving the living environment for wild animals. Recently, the organisation has issued an appeal to help it observe environmental changes based on the record of butterflies and protect the environment. In the area, the local people have planted many special flowers with the help of the organisation, aiming to see whether these flowers will interest the rare and beautiful butterflies. The Project officer Sarah Marshall says, "It will be a suitable habitat for butterflies. They are great 'indicator species' as they are easily affected by climate changes so they make a brillian early - warning system for the environment." She also points out that volunteers are needed to recourd the number or species of butterflies,and based on the change happening to the butterflies, the hidden environmental problems in the area can be found out in time. The organisation is seeking volunteers to help monitor butterflies from April through to September. They will walk a fixed route and record the different butterflies they encounter along the way.Each visit should take no more than two hours, and each volunteer is expected to visit once a month to count the wildlife. "Staff will provide back up, so if the weather is poor on the day you are to visit(butterflies don't like to fly in the rain, wind or if it's too cloudy) we can have someone else do your job," Sarah points out. No previous experience is necessary as training and support will be provided,but a keen interest is essential.

B: To protect the environment. C: To control butterfly population. D: To expand the area for wildlife.

Question: Read the article and select the best answer. Article: Americans often plan social gatherings on short notice, so don't be surprised if you get invited to someone's home or to see a movie or baseball game without much warning. If the time is convenient for you, surely accept their invitation. But if you're busy, don't be afraid to _ the invitation, perhaps suggesting a time that would be better. Your host won't be shamed. Invitations are usually sent in person or over the telephone. The main exception is for some formal occasions, in which case a written invitation will be mailed. You would normally receive a written invitation to a wedding . For a casual dinner invitation, don't arrive more than 5 minutes early, because your host may still be preparing for your visit. Arriving more than 10 minutes late is considered rude if very few people were invited. If many people were invited, it's OK to arrive a little late, even as much as half an hour late. For example, it's OK to arrive late for a party, for a potluck dinner or for a social gathering inviting a large group of people. If you're invited for dinner, it's proper to bring the host a bottle of wine, a gift basket of fruit, a box of candy , or a bouquet of flowers. Don't bring roses, as men often give roses to women on a date . If you wish to thank the host for his or her hospitality , it's right to call or send a brief written thank-you note the next day. Question: The passage is to tell us _ . Options: A: how to accept Americans' invitations. B: something about American social visits. C: something about American business visits. D: how to make a living in America.
Answer: B

Question: Read the article and select the best answer. Article: Finally, there is some good news for older dads. A new study shows that their children and even grandchildren may get a health benefit because of their older age. It's based on research into something called telomeres--tips on the ends of chromosomes Some previous studies have connected having longer telomeres with better health and longer lives. Telomeres haven't been proven to cause those benefits in the general population, but a number of researchers think they may hold secrets for things like longevity and cancer. As you age, telomeres shorten. However, previous studies have shown that the older a man is when he becomes a father, the longer the telomeres his children tend to have. The new research confirms that and finds it's extended to the grandchildren. That's a cheerier result for older dads than some other studies in recent years that indicate their kids are at higher risk for things like autism Carol Greider of Johns Hopkins University, who shared a Nobel Prize in 2009 for telomere research but didn't participate in the new study, said it's no surprise that the telomere effect would extend beyond children to grandchildren. She also said that since older fathers also tend to pass more potentially harmful genetic mutations , it's "not at all clear" whether advanced paternal age gives an overall health benefit to children. In a statement, the researchers who conducted the study said their study shouldn't be taken as a recommendation that men reproduce at older ages because there's a risk of genetic mutations. Some previous studies of the impact of older fatherhood have been less encouraging. In 2010, for example, at least two big studies confirmed a link to having children with autism. In 2008, a big Swedish study strengthened evidence linking bipolar disorder to older paternal ages. Question: According to the latest study, we know that the older dads are likely to _ . Options: A: have children with autism B: be cheerier than younger dads C: have children with shorter telomeres D: have grandchildren with longer telomeres

D
