小題4:a 
小題5:to
小題6:It
小題7:growing
小題8:that
小題9:ideal
小題10:of

試題分析:
小題1:Carry out是固定用法,意思是進(jìn)行。
小題2:修飾thin,用副詞形式。
小題3:表示現(xiàn)在進(jìn)行的動(dòng)作,且是被動(dòng),故用現(xiàn)在進(jìn)行時(shí)的被動(dòng)式。
小題4:表示泛指,故用不定冠詞a。
小題5:句意:到標(biāo)準(zhǔn)直徑的二十分之一,所以填to。
小題6:這里用作形式主語(yǔ),故用It。
小題7:表示主動(dòng),正在進(jìn)行,故用現(xiàn)在分詞。
小題8:這里含有同位語(yǔ)從句,且引導(dǎo)詞在從句中既不作任何成分,也沒(méi)有實(shí)際意義,故用that。
小題9:修飾名詞,故用形容詞。
小題10:表示……的,用of。

Everyone needs a break, and vacations are not meant for serious study. __小題1:__ The Spring Festival is coming up so this is the perfect time to discuss some great English language literature to take on a long train journey.
Before getting into the recommendations, you need to determine your English reading comprehension level. If you’re at the beginner level, there are two options: reading a children’s book or reading a book that you’ve read in Chinese translation. __小題2:__ If you’re at the intermediate level, popular books like pop fiction, mysteries and thrillers are good options. For advanced readers, classic works of literature or modern prize winners (Nobel, Pulitzer) are good options.
__小題3:__ When I pick up a book I like, even though the first few chapters are really hard to get through, I would try to get accustomed to the language the author uses. Generally, after the first few chapters, things get a lot easier, especially if I get involved in the story.
Another great way to keep yourself motivated is to find a friend who’s interested in reading the same book. You can make goals that you both want to achieve. __小題4:__
Some quick recommendations: Harry Potter, start with the first book and go on from there; the Narnia series; anything by US writer Michael Crichton; and if you like horror, US writer Stephen King is always unusual and fun. __小題5:__ Happy reading! 
A.If you pick a book which is so challenging, it will be too stressful.
B.The most important thing is to pick a book that you’re really interested in.
C.You may also enjoy your reading when hanging out with your family.

E. You can also discuss plot lines or vocabulary issues with each other by SMS or e-mail.
F. Instead, they’re a great way to take a break and enjoy a good book.
G. This will help you get over any unfamiliar words or phrases, since you’re already familiar with the story.
